Abstract
Copper serves as a co-factor for a host of metalloenzymes that contribute to malignant progression. The orally bioavailable copper chelating agent tetrathiomolybdate (TM) has been associated with a significant survival benefit in high-risk triple negative breast cancer (TNBC) patients. Despite these promising data, the mechanisms by which copper depletion impacts metastasis are poorly understood and this remains a major barrier to advancing TM to a randomized phase II trial. Here, using two independent TNBC models, we report a discrete subpopulation of highly metastatic SOX2/OCT4+ cells within primary tumors that exhibit elevated intracellular copper levels and a marked sensitivity to TM. Global proteomic and metabolomic profiling identifies TM-mediated inactivation of Complex IV as the primary metabolic defect in the SOX2/OCT4+ cell population. We also identify AMPK/mTORC1 energy sensor as an important downstream pathway and show that AMPK inhibition rescues TM-mediated loss of invasion. Furthermore, loss of the mitochondria-specific copper chaperone, COX17, restricts copper deficiency to mitochondria and phenocopies TM-mediated alterations. These findings identify a copper-metabolism-metastasis axis with potential to enrich patient populations in next-generation therapeutic trials.

Abstract
Abstract
Introduction There is a paucity of data on platinum-based chemotherapy in advanced breast cancer (ABC) from developing countries like India.
Objectives The objectives were to analyze the efficacy and safety of platinum-based chemotherapy in patients with ABC.
Materials and Methods This was a retrospective study of 35 patients with ABC who were treated with platinum-based chemotherapy (gemcitabine and carboplatin, [GC]) in a tertiary cancer center in India from August 2015 to November 2019. The inclusion criteria were patients with ABC, who had received palliative chemotherapy with GC. The exclusion criteria were patients who had received less than two cycles of GC and patients who received platinum-based chemotherapy for neuroendocrine carcinoma of the breast.
Results The median age was 45 years (range: 28–68 years). All patients were female (97%) except one male (3%). The histology was ductal carcinoma (77%), mixed (17%), and others (6%). Out of the 12 patients tested for breast cancer (BRCA) gene mutation, six patients had a BRCA mutation. Patients with metastatic and locally progressive disease were 91 and 9%, respectively. The median number of prior lines of systemic therapy for metastatic disease was 1 (range: 0–5). The median number of sites of metastasis was 2 (range: 0–5). Patients with visceral crises were 23%. The median number of cycles of GC chemotherapy received was 6 (range: 2–6). A dose reduction in chemotherapy was done in 74%. The responses among 34 evaluable patients were complete response (11%), partial response (24%), stable disease (41%), and progressive disease (24%). Grade 3 or more hematological and nonhematological toxicities were observed in 69 and 9%, respectively. The median progression-free survival and overall survival were 6 and 8 months, respectively. The 1-year progression-free survival and overall survival were 19 and 34%, respectively. Multivariate analysis showed that patients who had received more than 3 cycles had a better outcome.
Conclusion GC was an active and well-tolerated regimen in ABC regardless of the receptor status. Further prospective randomized studies are warranted to assess the optimal regimen in patients with triple-negative breast cancer.

Abstract
Papillomaviruses dysregulate the G1/S cell cycle transition in order to promote DNA synthesis in S phase, which is a requirement for viral replication. The human papillomaviruses (HPV) E6 and E7 oncoproteins mediate degradation of the cell cycle regulators p53 and Rb, which are two of the most universally disrupted tumor-suppressor genes in all of cancer. The G1/S checkpoint is activated in normal cells to allow sufficient time for DNA repair in G1 before proceeding to replicate DNA and risk propagating unrepaired errors. The TP53 pathway suppresses a variety of such errors, including translocation, copy number alterations, and aneuploidy, which are thus found in HPV-associated tumors similarly to HPV-negative tumors with other mechanisms of TP53 disruption. However, E6 and E7 maintain a variety of other virus–host interactions that directly disrupt a growing list of other DNA repair and chromatin remodeling factors, implying HPV-specific repair deficiencies. In addition, HPV-associated squamous cell carcinomas tumors clinically respond differently to DNA damaging agents compared to their HPV negative counterparts. The focus of this review is to integrate three categories of observations: (1) pre-clinical understanding as to the effect of HPV on DNA repair, (2) genomic signatures of DNA repair in HPV-associated tumor genomes, and (3) clinical responses of HPV-associated tumors to DNA damaging agents. The goals are to try to explain why HPV-associated tumors respond so well to DNA damaging agents, identify missing pieces, and suggest clinical strategies could be used to further improve treatment of these cancers.

Identification of a Hypoxia-Related Molecular Classification and Hypoxic Tumor Microenvironment Signature for Predicting the Prognosis of Patients with Triple-Negative Breast Cancer. Front Oncol 2021; 11:700062. [PMID: 34490098 PMCID: PMC8416750 DOI: 10.3389/fonc.2021.700062] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Accepted: 07/31/2021] [Indexed: 12/31/2022] Open
Abstract
Purpose The hypoxic tumor microenvironment was reported to be involved in different tumorigenesis mechanisms of triple-negative breast cancer (TNBC), such as invasion, immune evasion, chemoresistance, and metastasis. However, a systematic analysis of the prognostic prediction models based on multiple hypoxia-related genes (HRGs) has not been established in TNBC before in the literature. We aimed to develop and verify a hypoxia gene signature for prognostic prediction in TNBC patients. Methods The RNA sequencing profiles and clinical data of TNBC patients were generated from the TCGA, GSE103091, and METABRIC databases. The TNBC-specific differential HRGs (dHRGs) were obtained from differential expression analysis of hypoxia cultured TNBC cell lines compared with normoxic cell lines from the GEO database. Non-negative matrix factorization (NMF) method was then performed on the TNBC patients using the dHRGs to explore a novel molecular classification on the basis of the dHRG expression patterns. Prognosis-associated dHRGs were identified by univariate and multivariate Cox regression analysis to establish the prognostic risk score model. Results Based on the expressions of 205 dHRGs, all the patients in the TCGA training cohort were categorized into two subgroups, and the patients in Cluster 1 demonstrated worse OS than those in Cluster 2, which was validated in two independent cohorts. Additionally, the effects of somatic copy number variation (SCNV), somatic single nucleotide variation (SSNV), and methylation level on the expressions of dHRGs were also analyzed. Then, we performed Cox regression analyses to construct an HRG-based risk score model (3-gene dHRG signature), which could reliably discriminate the overall survival (OS) of high-risk and low-risk patients in TCGA, GSE103091, METABRIC, and BMCHH (qRT-PCR) cohorts. Conclusions In this study, a robust predictive signature was developed for patients with TNBC, indicating that the 3-gene dHRG model might serve as a potential prognostic biomarker for TNBC.

Abstract
Cisplatin is an effective chemotherapeutic agent in facilitating the inhibition of proliferation, migration, and invasion in cancerous cells. However, the detailed mechanism of the regulation by cisplatin of human breast cancer cells is still unclear. This study aimed to investigate the mechanism of kruppel-like factor 2 (KLF2) transcription factor in cisplatin therapy for breast cancer. RT-qPCR was performed to quantify the expression of KLF2 and WEE1 in clinical tissue samples from breast cancer patients and in MDA-MB-231 cells. ChIP assay and dual-luciferase reporter assay were used to analyze the potential-binding sites of KLF2 and WEE1 promoter. Gain- or loss-of-function approaches were used to manipulate KLF2 and WEE1 in cisplatin-treated MDA-MB-231 cells, and the mechanism of KLF2 in breast cancer was evaluated both via CCK-8 assay, flow cytometry, Transwell assay, and Western blot. Further validation of the KLF2 was performed on nude mouse models. Breast cancer tissues and cells showed a relative decline of KLF2 expression and abundant WEE1 expression. Cisplatin inhibited the proliferation, migration, and invasion of MDA-MB-231 cells. Overexpression of KLF2 enhanced the inhibitory effect of cisplatin on the malignant characteristics of MDA-MB-231 cells in vitro. KLF2 targeted WEE1 and negatively regulated its expression, thus enhancing the sensitivity to cisplatin of breast cancer cells as well as tumor-bearing mice. Overall, these results suggest that KLF2 can potentially inhibit WEE1 expression and sensitize breast cancer cells to cisplatin, thus presenting a promising adjunct treatment.

Abstract
Breast cancer (BC) prognosis and therapeutic sensitivity could not be predicted efficiently. Previous evidence have shown the vital roles of CDKN1C in BC. Therefore, we aimed to construct a CDKN1C‐based model to accurately predicting overall survival (OS) and treatment responses in BC patients. In this study, 995 BC patients from The Cancer Genome Atlas database were selected. Kaplan‐Meier curve, Gene set enrichment and immune infiltrates analyses were executed. We developed a novel CDKN1C‐based nomogram to predict the OS, verified by the time‐dependent receiver operating characteristic curve, calibration curve and decision curve. Therapeutic response prediction was followed based on the low‐ and high‐nomogram score groups. Our results indicated that low‐CDKN1C expression was associated with shorter OS and lower proportion of naïve B cells, CD8 T cells, activated NK cells. The predictive accuracy of the nomogram for 5‐year OS was superior to the tumour‐node‐metastasis stage (area under the curve: 0.746 vs. 0.634, p < 0.001). The nomogram exhibited excellent predictive performance, calibration ability and clinical utility. Moreover, low‐risk patients were identified with stronger sensitivity to therapeutic agents. This tool can improve BC prognosis and therapeutic responses prediction, thus guiding individualized treatment decisions.

Abstract
Background This study sought to examine the efficacy and adverse reactions of capecitabine and lobaplatin in the treatment of metastatic human epidermal growth factor receptor 2 (HER-2) negative breast cancer (BC). Methods This retrospective study examined 45 patients diagnosed with advanced HER-2 negative BC. Patients were enrolled in this study from November 2015 to June 2019. The patients received capecitabine and lobaplatin combination therapy. The therapeutic efficacy and side effects were evaluated after at least 2 cycles of treatment. Results Therapeutic efficacy and adverse reactions were evaluated in 38 patients, comprising 12 cases of partial response (PR), 19 cases of stable disease (SD), and 7 cases of progressive disease (PD). Among these, 3 patients required treatment delays or dose reductions for subsequent cycles, and 2 patients discontinued treatment. The overall response rate (ORR) was 31.58% and the disease control rate (DCR) was 81.58%. The ORR and DCR for hormone receptor positive, HER-2 negative (HR+/HER-2−) and triple negative breast cancer (TNBC) patients were 31.82% and 31.25%, and 86.36% and 75%, respectively. The median progression free survival (PFS) was 8 months, 6 months, and 6 months in patients receiving the therapeutics as a first-line, second-line, or third-line and beyond treatment, respectively. The main side effects were myelosuppression, including granulocytopenia, thrombocytopenia, and anemia. Among patients with grade 1 side effects or above, 28 patients (73.68%) had myelosuppression, and 13 patients (34.21%) had gastrointestinal reactions. Further, we investigated the association between side effects and clinical outcomes, and found that PFS was increased in patients with myelosuppression and gastrointestinal reactions. Conclusions Capecitabine and lobaplatin combination therapy was effective and well tolerated among patients with advanced HER-2 negative BC.

Exosomal annexin A6 induces gemcitabine resistance by inhibiting ubiquitination and degradation of EGFR in triple-negative breast cancer. Cell Death Dis 2021; 12:684. [PMID: 34238922 PMCID: PMC8266800 DOI: 10.1038/s41419-021-03963-7] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 06/19/2021] [Accepted: 06/22/2021] [Indexed: 01/07/2023]
Abstract
Exosomes are carriers of intercellular information that regulate the tumor microenvironment, and they have an essential role in drug resistance through various mechanisms such as transporting RNA molecules and proteins. Nevertheless, their effects on gemcitabine resistance in triple-negative breast cancer (TNBC) are unclear. In the present study, we examined the effects of exosomes on TNBC cell viability, colony formation, apoptosis, and annexin A6 (ANXA6)/EGFR expression. We addressed their roles in gemcitabine resistance and the underlying mechanism. Our results revealed that exosomes derived from resistant cancer cells improved cell viability and colony formation and inhibited apoptosis in sensitive cancer cells. The underlying mechanism included the transfer of exosomal ANXA6 from resistant cancer cells to sensitive cancer cells. Isobaric peptide labeling–liquid chromatography–tandem mass spectrometry and western blotting revealed that ANXA6 was upregulated in resistant cancer cells and their derived exosomes. Sensitive cancer cells exhibited resistance with increased viability and colony formation and decreased apoptosis when ANXA6 was stably overexpressed. On the contrary, knockdown ANXA6 restored the sensitivity of cells to gemcitabine. Co-immunoprecipitation expression and GST pulldown assay demonstrated that exosomal ANXA6 and EGFR could interact with each other and exosomal ANXA6 was associated with the suppression of EGFR ubiquitination and downregulation. While adding lapatinib reversed gemcitabine resistance induced by exosomal ANXA6. Moreover, ANXA6 and EGFR protein expression was correlated in TNBC tissues, and exosomal ANXA6 levels at baseline were lower in patients with highly sensitive TNBC than those with resistant TNBC when treated with first-line gemcitabine-based chemotherapy. In conclusion, resistant cancer cell-derived exosomes induced gemcitabine resistance via exosomal ANXA6, which was associated with the inhibition of EGFR ubiquitination and degradation. Exosomal ANXA6 levels in the serum of patients with TNBC might be predictive of the response to gemcitabine-based chemotherapy.

Abstract
Aim: Two poly(ADP-ribose) polymerase (PARP) inhibitors olaparib and talazoparib are approved for patients with germline BRCA-mutated (gBRCAm) HER2-negative metastatic breast cancer. Methods: A Bayesian fixed-effects indirect treatment comparison (ITC) analysis was performed to simulate the comparative efficacy (primary outcome of progression-free survival [PFS]) and safety of PARP inhibitor monotherapy. Results: ITC of data from the OlympiAD (olaparib) and EMBRACA (talazoparib) studies suggested no significant difference in efficacy (PFS) between olaparib and talazoparib. However, there were differences in specific adverse events; patients receiving olaparib had a higher rate of nausea and vomiting, while those receiving talazoparib had a higher rate of alopecia and anemia. Discussion: These data support the benefit of the PARP inhibitor class in gBRCAm HER2-negative metastatic breast cancer.

Abstract
Cisplatin is a chemotherapy drug commonly used in cancer treatment. Tumour cells are more sensitive to cisplatin than normal cells. Cisplatin exerts an antitumour effect by interfering with DNA replication and transcription processes. However, the drug-resistance properties of tumour cells often cause loss of cisplatin efficacy and failure of chemotherapy, leading to tumour progression. Owing to the large amounts of energy and compounds required by tumour cells, metabolic reprogramming plays an important part in the occurrence and development of tumours. The interplay between DNA damage repair and metabolism also has an effect on cisplatin resistance; the molecular changes to glucose metabolism, amino acid metabolism, lipid metabolism, and other metabolic pathways affect the cisplatin resistance of tumour cells. Here, we review the mechanism of action of cisplatin, the mechanism of resistance to cisplatin, the role of metabolic remodelling in tumorigenesis and development, and the effects of common metabolic pathways on cisplatin resistance.

A triple combination gemcitabine + romidepsin + cisplatin to effectively control triple-negative breast cancer tumor development, recurrence, and metastasis. Cancer Chemother Pharmacol 2021; 88:415-425. [PMID: 34043046 DOI: 10.1007/s00280-021-04298-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 05/15/2021] [Indexed: 12/14/2022]
Abstract
PURPOSE Triple-negative breast cancer (TNBC) is an aggressive, lethal, heterogeneous type of breast cancer (BC). TNBC tends to have a lower response rate to chemotherapy and a lower 5-year survival rate than other types of BC due to recurrence and metastasis. Our previous study revealed that a combination of gemcitabine, romidepsin, and cisplatin was efficacious in controlling TNBC tumor development. In this study, we extended our investigation of gemcitabine + romidepsin + cisplatin in controlling TNBC tumor recurrence and metastasis. METHODS We investigated the ability of gemcitabine + romidepsin + cisplatin to control cell survival and invasiveness using cell viability, soft agar colony formation, and transwell invasion assays. We determined the efficacy of gemcitabine + romidepsin + cisplatin in controlling tumor recurrence and metastasis using cell-derived xenograft animal models. We used immunoblotting to study signaling modulators regulated by gemcitabine + romidepsin + cisplatin in TNBC cells and tumor tissues. RESULTS Treatment with gemcitabine + romidepsin + cisplatin reduced the TNBC MDA-MB231 and MDA-MB468 cell survival to ~ 50% and ~ 15%, as well as invasiveness to ~ 31% and ~ 13%, respectively. Gemcitabine + romidepsin + cisplatin suppressed modulators involved in epithelial-mesenchymal transition in an ROS-dependent manner. Controlling tumor recurrence, the Gem plus Rom + Cis regimen (~ 112%) was more efficacious than the Gem plus Cis regimen (~ 21%) in tumor growth inhibition. The Gem plus Rom + Cis regimen efficaciously reduced the development of metastatic nodules to 20% in animals. CONCLUSION The gemcitabine plus romidepsin + cisplatin regimen was highly efficacious in controlling TNBC tumor development, recurrence, and metastasis in animals. The combination regimen should be poised for efficient translation into clinical trials for controlling the recurrence and metastasis, ultimately contributing to reducing mortality and improving TNBC patients' quality of life.

Abstract
Cisplatin is a widely used antineoplastic agent, whose efficacy is limited by primary and acquired therapeutic resistance. Recently, a bladder cancer genome-wide CRISPR/Cas9 knock-out screen correlated cisplatin sensitivity to multiple genetic biomarkers. Among the screen’s top hits was the HECT domain-containing ubiquitin E3 ligase (HUWE1). In this review, HUWE1 is postulated as a therapeutic response modulator, affecting the collision between platinum-DNA adducts and the replication fork, the primary cytotoxic action of platins. HUWE1 can alter the cytotoxic response to platins by targeting essential components of the DNA damage response including BRCA1, p53, and Mcl-1. Deficiency of HUWE1 could lead to enhanced DNA damage repair and a dysfunctional apoptotic apparatus, thereby inducing resistance to platins. Future research on the relationship between HUWE1 and platins could generate new mechanistic insights into therapy resistance. Ultimately, HUWE1 might serve as a clinical biomarker to tailor cancer treatment strategies, thereby improving cancer care and patient outcomes.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC), the most common type of breast cancer, is associated with poor patient prognosis. Platinum-containing chemotherapies are commonly used in the treatment and prevention of advanced TNBC. OBJECTIVES AND METHODS To systematically evaluate the effectiveness and safety of platinum-containing chemotherapies in patients with advanced TNBC, we searched several databases, including PubMed, Medline, Embase, ClinicalTrials.gov, Cochrane Library, CNKI, CBM, and the Chinese Cochrane Center, to collect published randomized controlled clinical studies of platinum-containing chemotherapies for advanced TNBC before November 2020. The meta-analysis was performed using Review Manager version 5.3. To assess effectiveness and safety, dichotomous and continuous variables were assessed using odds ratio (OR) and mean difference (MD), respectively, with 95% CI. RESULTS A total of 1,222 patients with advanced TNBC were enrolled in 11 eligible trials, including 489 patients in the treatment group (platinum-containing) and 447 patients in the control group (non-platinum-containing). We also retrieved information whether a PARP inhibitor was combined with platinum-containing chemotherapy for patients with metastatic TNBC and identified 224 patients who received a PARP inhibitor combined with platinum-containing chemotherapy and 62 patients in the platinum-containing group who did not. The platinum-containing chemotherapy group had a significantly better objective response rate (OR 1.43, 95% CI 1.20-1.71, p < 0.001) and longer progression-free survival (PFS; MD 1.15, 95% CI 0.03-2.28, p < 0.05) than the non-platinum-containing chemotherapy group. However, there was no significant difference in overall survival (OS) of patients with advanced TNBC between the two groups (MD 2.04, 95% CI -0.83 to 4.91, p > 0.05). Related adverse effects of platinum-containing chemotherapies involved gastrointestinal reaction, myelosuppression and liver function damage. Platinum-containing chemotherapies were not associated with an increased incidence of adverse side effects compared with non-platinum-containing chemotherapies, with the exception of nausea and vomiting (OR 2.22, 95% CI 1.10-4.46, p < 0.05). Furthermore, the addition of the PARP inhibitor iniparib to gemcitabine and carboplatin treatment improved the rate of clinical benefit, OS and PFS. CONCLUSIONS Platinum-containing chemotherapy remains a highly recommended therapeutic regimen due to greater effectiveness and tolerance for patients with advanced TNBC.

Abstract
This review focuses on studies of coordination and organometallic compounds as potential chemotherapeutics against triple negative breast cancer (TNBC) which has one of the poorest prognoses and worst survival rates from all breast cancer types. At present, chemotherapy is still the standard of care for TNBC since only one type of targeted therapy has been recently developed. References for metal-based compounds studied in TNBC cell lines will be listed, and those of metal-specific reviews, but a detailed overview will also be provided on compounds studied in vivo (mostly in mice models) and those compounds for which some preliminary mechanistic data was obtained (in TNBC cell lines and tumors) and/or for which bioactive ligands have been used. The main goal of this review is to highlight the most promising metal-based compounds with potential as chemotherapeutic agents in TNBC.

Abstract
The heterogeneity of triple negative breast cancer (TNBC) is reflected in a bizarre response to therapy. Although it is chemotherapy sensitive, the failure is the usual pathway either in local or distance status. With progression in Gene Expression Profile (GEP) and other molecular techniques, TNBC is divided into sub-types with unique pathways. In the current review, we are trying to highlight based on the molecular classification of TNBC and the management based on every type.

A redox probe screens MTHFD1 as a determinant of gemcitabine chemoresistance in cholangiocarcinoma. Cell Death Discov 2021; 7:89.

Abstract
Cholangiocarcinoma (CCA) is a type of solid tumor derived from the bile duct epithelium that features universal gemcitabine resistance. Here, we utilized a gene-encoded ROS biosensor probe (HyPer3 probe) to sort subpopulations with different redox statuses from CCA cells. The isolated HyPer-low subpopulation CCA cells, which exhibited relatively lower cellular ROS levels, exhibited higher chemoresistance to gemcitabine than HyPer-high subpopulation CCA cells in vitro and in vivo. Mechanistically, increased expression of MTHFD1 was found in HyPer-low cells. Knocking down MTHFD1 in HyPer-low cells enhanced cellular ROS and restored sensitivity to gemcitabine. Furthermore, the MTHFD1 inhibitor antifolate compound methotrexate (MTX) increased cellular ROS, and combining gemcitabine with MTX effectively suppressed cholangiocarcinoma cell growth. In summary, the MTHFD1 level mediated the heterogeneous cellular redox status in CCA, which resulted in chemoresistance to gemcitabine. Our data suggest a novel strategy for CCA chemotherapy.

Abstract
Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype that promotes a higher risk of metastasis and cancer reoccurrence. Cisplatin is one of the potential anticancer drugs for treating TNBC. However, the occurrence of cisplatin resistance still remains one of the challenges in fully eradicating TNBC. The presence of cancer stem cells (CSCs) has been proposed as one of the factors contributing to the development of cisplatin resistance. In this study, we aimed to characterize the cellular properties and reveal the corresponding putative target genes involved in cisplatin resistance associated with CSCs using the TNBC cell line (MDA-MB-231). CSC-like cells were isolated from parental cells and the therapeutic effect of cisplatin on CSC-like cells was compared to that of the parental cells via cell characterization bioassays. A PCR array was then conducted to study the expression of cellular mRNA for each subpopulation. As compared to treated parental cells, treated CSCs displayed lower events of late apoptosis/necrosis and G2/M phase cell arrest, with higher mammosphere formation capacity. Furthermore, a distinct set of putative target genes correlated to the Hedgehog pathway and angiogenesis were dysregulated solely in CSC-like cells after cisplatin treatment, which were closely related to the regulation of chemoresistance and self-renewability in breast cancer. In summary, both cellular and gene expression studies suggest the attenuated cytotoxicity of cisplatin in CSC-like cells as compared to parental cells. Understanding the role of dysregulated putative target genes induced by cisplatin in CSCs may aid in the potential development of therapeutic targets for cisplatin-resistant breast cancer.

Abstract
An amphiphilic peptide dendrimer conjugated with gemcitabine (GEM), PEGylated dendron-Gly-Phe-Leu-Gly-GEM (PEGylated dendron-GFLG-GEM), is developed as a nano-prodrug for breast cancer therapy. The self-assembled behavior is observed under a transmission electron microscopy and dynamic light scattering. The negatively charged surface and hydrodynamic size of the amphiphilic nanosized prodrug supported that the prodrug can maintain the stability of GEM during circulation and accumulate in the tumor tissue. Drug release assays are conducted to monitor the release of GEM from this nanodrug delivery system in response to the tumor microenvironment, and these assays confirm that GEM released from the nanocarrier is identical to free GEM. The GEM prodrug can prevent proliferation of tumor cells. The therapeutic effect against breast cancer is systematically investigated using an in vivo animal model. Immunohistochemical results are aligned with the significantly enhanced anticancer efficacy of GEM released from the prodrug. This self-assembled amphiphilic drug delivery nanocarrier may broaden the application for GEM and other anticancer agents for breast cancer chemotherapy.

NLRP3 augmented resistance to gemcitabine in triple-negative breast cancer cells via EMT/IL-1β/Wnt/β-catenin signaling pathway. Biosci Rep 2021; 40:225471. [PMID: 32578856 PMCID: PMC7335831 DOI: 10.1042/bsr20200730] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 05/30/2020] [Accepted: 06/08/2020] [Indexed: 02/06/2023] Open
Abstract
Background: Gemcitabine is widely used in the treatment of breast cancer (BC). However, the resistance to drugs remains a tough concern. The study explored the potential mechanism concerning gemcitabine resistance in triple-negative BC (TNBC) in vitro. Methods: TNBC cells (TNBCC) and gemcitabine-resistance cell lines (GRC) were used. We investigated the sensitivity to gemcitabine responsive to regulation of Nod-like receptor protein 3 (NLRP3) expression in TNBCC in different gemcitabine concentrations. RT-PCR checked NLRP3 mRNA expression and MTT assessed the cell cytotoxicity. Gemcitabine resistance was studied in GRC exposed to 0, 1, 3, 5 nm gemcitabine after GRC were treated with NLRP3 agonist Nigericin sodium salt (NSS) or antagonist CY-09. Epithelial-to-mesenchymal transition (EMT) biomarkers were evaluated via RT-PCR and inflammasome IL-1β, β-catenin content and GSK-3β activity were measured by ELISA methods. Last, we inactivated the signaling and examined the NLRP3, EMT mRNA expression by RT-PCR, IL-1β, β-catenin content and GSK-3β activity by ELISA and cell cytotoxicity through MTT. Results: NLRP3 up-regulation improved cell survival and reduced sensitivity to gemcitabine (P<0.05). NLRP3 had higher expression in GRC than TNBCC. GRC cell viability dropped as the gemcitabine concentration increased. NLRP3 up-regulation added to resistance to gemcitabine in GRC (P<0.05). NLRP3 agonist might induce EMT process, activate wnt/β-catenin signaling and IL-1β, while inactivation of wnt/β-catenin signaling could result in the inhibition of NLRP3, IL-1β and EMT as well as cell viability in GRC (P<0.05). Conclusion: NLRP3 could enhance resistance to gemcitabine via IL-1β/EMT/Wnt/β-catenin signaling, which suggested that NLRP3 antagonist CY-09 might be incorporated into gemcitabine treatment for TNBC.

Abstract
OBJECTIVES To assess the efficacy and toxicity of gemcitabine-based induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) in locally advanced nasopharyngeal carcinoma (LA-NPC). METHODS Both observational studies (OBS) and randomized controlled trials (RCT) were included in the meta-analysis. Systematic online searches were conducted in Web of Sciences, PubMed, Embase, meeting proceedings and ClinicalTrials.gov from the inception to May 25, 2020. The primary endpoint of interest was overall survival. RESULTS five OBSs and 2 RCTs including 1680 patients were incorporated in the analysis. The evidence from the RCTs showed that adding gemcitabine-based induction chemotherapy to CCRT significantly improved progression free survival (hazard ratio (HR): 0.60, 95% confidence interval (CI): 0.40-0.88; P = .010; chi square P = .25; I2 = 24%) and overall survival (HR: 0.47; 95% CI: 0.28-0.80; P = 0.005; chi square P = .49, I2 = 0%) and was related to a higher risk of hematological toxicities. Furthermore, based on the data of OBSs, overall survival (HR: 0.52; 95% CI: 0.31-0.88; P = .02; chi square P = .37, I2 = 6%) was significantly improved in patients treated with gemcitabine-based induction chemotherapy compared to those treated with taxane-based induction chemotherapy. However, the progression free survival (HR: 0.67; 95% CI: 0.45-1.01; P = .06; chi square P = .74; I2 = 0%) showed no significant difference. CONCLUSIONS For LA-NPC patients, adding gemcitabine-based induction chemotherapy to CCRT significantly improved overall survival and progression free survival with a higher risk of hematological toxicities when compared to CCRT alone. Also, gemcitabine-based regimen could be used as an alternative induction chemotherapy regimen to taxane-based regimen in the treatment of LA-NPC.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 84:153492. [PMID: 33640782 DOI: 10.1016/j.phymed.2021.153492] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 01/07/2021] [Accepted: 01/29/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Sulforaphane (SFN) is a naturally occurring organosulfur compound found in cruciferous vegetables such as broccoli, brussels sprouts and cabbage. SFN is known for its multiple therapeutic properties, such as HDAC inhibitory, chemo preventive and anti-cancer effects. Cisplatin (CIS) has limited effect against metastatic triple-negative breast cancer (TNBC). Additionally, CIS impose severe side effects to normal cells, and later TNBC cells develops resistance. Studies suggest that the overexpression of sirtuins (SIRTs) promotes CIS resistance and metastasis by activating epithelial-to-mesenchymal transition (EMT) pathway in TNBC. PURPOSE In view of the above information, we investigated the therapeutic efficacy of SFN, in combination with CIS against TNBC metastasis and CIS resistance. METHODS The anti-cancerous effect of SFN-CIS combination on human TNBC cell lines was demonstrated by utilizing MTT assay and, apoptosis and cell cycle assay followed by FACS analysis. The synergistic effect of SFN-CIS combination on the experimental metastasis was demonstrated by utilizing migration, invasion, chemotaxis, mammosphere and colony formation assay on human TNBC MDA-MB-231 and MDA-MB-468 cells. The role of SIRTs-mediated EMT signaling axis in the metastasis and chemoresistance was investigated by western blotting technique as well as sirtuin activity tests. This was further validated by using Chromatin immunoprecipitation (ChIP) analysis. RESULTS We found that SFN-CIS combination synergistically inhibits cellular growth of MDA-MB-231 and MDA-MB-468 cells. More importantly, SFN was found to protect normal kidney cells from CIS-induced toxicity. Further, SFN-CIS combination was found to synergistically inhibit metastatic-events via significantly altering EMT markers which was further associated with the suppression of SIRTs functions in TNBC cells. ChIP analysis validated that SFN-CIS combination suppresses EMT mechanism through altered chromatin modifications at E-cadherin promoter resulting in its re-expression. CONCLUSION The results of the current study suggests that CIS when supplemented with SFN, inhibits metastasis and stemness potential of TNBC cells by down regulating SIRTs-mediated EMT cascade. Overall this study affirms that, this novel combination could be a promising strategy against SIRT-mediated TNBC metastasis and CIS-resistance.

Abstract
BACKGROUND Kounis syndrome is an acute coronary syndrome that appears in the setting of anaphylactic reaction or hypersensitivity. Many drugs and environmental exposures have been identified as potential offenders, and diagnosis and treatment can be challenging. CASE PRESENTATION A 62-year-old man with recurrent bladder cancer underwent an intra-iliac artery epirubicin injection. After the injection, he developed chest pain and a systemic allergic reaction, with electrocardiographic alterations and elevated troponin-I levels. Emergent coronary angiography showed right coronary artery spasm and no stenosis of the other coronary arteries. This reaction was considered compatible with an allergic coronary vasospasm. A diagnosis of Kounis syndrome was made. CONCLUSIONS Kounis syndrome is common, but a prompt diagnosis is often not possible. This case is the first to suggest that an intraarterial epirubicin injection could potentially be one of its triggers. All physicians should be aware of the pathophysiology of this condition to better recognize it and start appropriate treatment; this will prevent aggravation of the vasospastic cardiac attacks and yield a better outcome.

Abstract
Background Triple negative breast cancer (TNBC) is one of the most biologically aggressive breast cancers and lacks effective treatment options, resulting in a poor prognosis. Therefore, studies aiming to explore new therapeutic strategies for advanced TNBC are urgently needed. According to recent studies, microRNA-124 (miR124) not only inhibits tumour growth but also increases the sensitivity of TNBC to paclitaxel (PTX), suggesting that a platform combining PTX and miR124 may be an advanced solution for TNBC. Results Herein, we constructed a stepped cleavable calcium phosphate composite lipid nanosystem (CaP/LNS) to codeliver PTX and miR124 (PTX/miR124-NP). PTX/miR124-NP exhibited superior tumor microenvironment responsive ability, in which the surface PEG layer was shed in the mildly acidic environment of tumor tissues and exposed oligomeric hyaluronic acid (o-HA) facilitated the cellular uptake of CaP/LNS by targeting the CD44 receptor on the surface of tumor cells. Inside tumour cells, o-HA detached from CaP/LNS due to the reduction of disulfide bonds by glutathione (GSH) and inhibited tumour metastasis. Then, PTX and miR124 were sequentially released from CaP/LNS and exerted synergistic antitumour effects by reversing the Epithelial-Mesenchymal Transition (EMT) process in MDA-MB-231 cells. Moreover, PTX/miR124-NP showed significant antitumour efficiency and excellent safety in mice bearing MDA-MB-231 tumours. Conclusion Based on these results, the codelivery of PTX and miR124 by the CaP/LNS nanosystem might be a promising therapeutic strategy for TNBC.![]()

Abstract
Question Does a paclitaxel-plus-carboplatin (PCb) as adjuvant treatment in women with operable triple-negative breast cancer offer superior benefit compared with a standard-dose CEF-T regimen (cyclophosphamide, epirubicin, and fluorouracil followed by docetaxel)? Findings In this randomized phase 3 clinical trial conducted at 9 cancer centers and hospitals in China and including 647 patients, after a median follow-up of 62 months, 5-year disease-free survival rate was statistically significantly higher in the PCb group compared with the CEF-T group. Meaning Results of this study suggest that a paclitaxel-plus-carboplatin regimen may be an alternative adjuvant chemotherapy choice for patients with operable triple-negative breast cancer. Importance The value of platinum-based adjuvant chemotherapy in patients with triple-negative breast cancer (TNBC) remains controversial, as does whether BRCA1 and BRCA2 (BRCA1/2) germline variants are associated with platinum treatment sensitivity. Objective To compare 6 cycles of paclitaxel plus carboplatin (PCb) with a standard-dose regimen of 3 cycles of cyclophosphamide, epirubicin, and fluorouracil followed by 3 cycles of docetaxel (CEF-T). Design, Setting, and Participants This phase 3 randomized clinical trial was conducted at 9 cancer centers and hospitals in China. Between July 1, 2011, and April 30, 2016, women aged 18 to 70 years with operable TNBC after definitive surgery (having pathologically confirmed regional node-positive disease or node-negative disease with tumor diameter >10 mm) were screened and enrolled. Exclusion criteria included having metastatic or locally advanced disease, having non-TNBC, or receiving preoperative anticancer therapy. Data were analyzed from December 1, 2019, to January 31, 2020, from the intent-to-treat population as prespecified in the protocol. Interventions Participants were randomized to receive PCb (paclitaxel 80 mg/m2 and carboplatin [area under the curve = 2] on days 1, 8, and 15 every 28 days for 6 cycles) or CEF-T (cyclophosphamide 500 mg/m2, epirubicin 100 mg/m2, and fluorouracil 500 mg/m2 every 3 weeks for 3 cycles followed by docetaxel 100 mg/m2 every 3 weeks for 3 cycles). Main Outcomes and Measures The primary end point was disease-free survival (DFS). Secondary end points included overall survival, distant DFS, relapse-free survival, DFS in patients with germline variants in BRCA1/2 or homologous recombination repair (HRR)–related genes, and toxicity. Results A total of 647 patients (mean [SD] age, 51 [44-57] years) with operable TNBC were randomized to receive CEF-T (n = 322) or PCb (n = 325). At a median follow-up of 62 months, DFS time was longer in those assigned to PCb compared with CEF-T (5-year DFS, 86.5% vs 80.3%, hazard ratio [HR] = 0.65; 95% CI, 0.44-0.96; P = .03). Similar outcomes were observed for distant DFS and relapse-free survival. There was no statistically significant difference in overall survival between the groups (HR = 0.71; 95% CI, 0.42-1.22, P = .22). In the exploratory and hypothesis-generating subgroup analyses of PCb vs CEF-T, the HR for DFS was 0.44 (95% CI, 0.15-1.31; P = .14) in patients with the BRCA1/2 variant and 0.39 (95% CI, 0.15-0.99; P = .04) in those with the HRR variant. Safety data were consistent with the known safety profiles of relevant drugs. Conclusions and Relevance These findings suggest that a paclitaxel-plus-carboplatin regimen is an effective alternative adjuvant chemotherapy choice for patients with operable TNBC. In the era of molecular classification, subsets of TNBC sensitive to PCb should be further investigated. Trial Registration ClinicalTrials.gov Identifier: NCT01216111

Abstract
We optimized our previously reported proline-based STAT3 inhibitors into an exciting new series of (R)-azetidine-2-carboxamide analogues that have sub-micromolar potencies. 5a, 5o, and 8i have STAT3-inhibitory potencies (IC50) of 0.55, 0.38, and 0.34 μM, respectively, compared to potencies greater than 18 μM against STAT1 or STAT5 activity. Further modifications derived analogues, including 7e, 7f, 7g, and 9k, that addressed cell membrane permeability and other physicochemical issues. Isothermal titration calorimetry analysis confirmed high-affinity binding to STAT3, with KD of 880 nM (7g) and 960 nM (9k). 7g and 9k inhibited constitutive STAT3 phosphorylation and DNA-binding activity in human breast cancer, MDA-MB-231 or MDA-MB-468 cells. Furthermore, treatment of breast cancer cells with 7e, 7f, 7g, or 9k inhibited viable cells, with an EC50 of 0.9-1.9 μM, cell growth, and colony survival, and induced apoptosis while having relatively weaker effects on normal breast epithelial, MCF-10A or breast cancer, MCF-7 cells that do not harbor constitutively active STAT3.

Abstract
Triple-negative breast cancer (TNBC) is an aggressive breast type of cancer with no expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2). It is a highly metastasized, heterogeneous disease that accounts for 10-15% of total breast cancer cases with a poor prognosis and high relapse rate within five years after treatment compared to non-TNBC cases. The diagnostic and subtyping of TNBC tumors are essential to determine the treatment alternatives and establish personalized, targeted medications for every TNBC individual. Currently, TNBC is diagnosed via a two-step procedure of imaging and immunohistochemistry (IHC), which are operator-dependent and potentially time-consuming. Therefore, there is a crucial need for the development of rapid and advanced technologies to enhance the diagnostic efficiency of TNBC. This review discusses the overview of breast cancer with emphasis on TNBC subtypes and the current diagnostic approaches of TNBC along with its challenges. Most importantly, we have presented several promising strategies that can be utilized as future TNBC diagnostic modalities and simultaneously enhance the efficacy of TNBC diagnostic.

Abstract
MicroRNA-205 (miR-205) is believed to be related to the progress of tumors. HOXD9 has been proved to be expressed abnormally in several kinds of cancers. However, the role of miR-205 and HOXD9 in breast cancer remains unclear. The biological role of miR-205 in breast cancer cell proliferation and chemoresistance was investigated. The expression of miR-205 in clinical tissues and breast cancer cell lines were analyzed using quantitative real-time PCR test (qRT-PCR). Overexpression and knockdown models of miR-205 were established to study cell proliferation and chemotherapy-resistant. Moreover, the potential relationships between miR-205 and HOXD9/Snail1 were measured using qRT-PCR, western blot, and chemotherapy-resistant study. miR-205 was lowly expressed in breast cancer tissues and cell lines. Overexpression of miR-205 could inhibit cell proliferation and chemotherapy-resistance. Moreover, we proved that miR-205 could target the HOXD9-Snail1 axis to suppress triple negative breast cancer cell proliferation and chemoresistance. The activation of Snail1 gene by HOXD9 was also proved in this study. The present study may provide a novel insight for the therapeutic strategies of breast cancer through targeting miR-205/HOXD9/Snail1.

[PMID: 33977814 PMCID: PMC8120541 DOI: 10.1177/15330338211016369] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 04/03/2021] [Accepted: 04/19/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Triple-negative breast cancer constitutes approximately 12%-17% of all breast cancer cases, and >33% of patients develop distant metastases. Systemic cytotoxic chemotherapy is the primary treatment for patients with metastatic triple-negative breast cancer; however, the role of first-line platinum-based chemotherapy in these patients remains controversial. This meta-analysis evaluated the efficacy and safety of platinum-based first-line chemotherapy for patients with metastatic triple-negative breast cancer. METHODS We systematically searched the PubMed, Embase, Cochrane, and Clinical Trials registry databases up to June 1, 2020 to identify randomized controlled trials that investigated platinum-based vs. first-line platinum-free chemotherapy in patients with metastatic triple-negative breast cancer. We used fixed and random effects models to calculate pooled hazard ratios and odds ratios with 95% confidence intervals for progression-free and overall survival, objective response rates, and grade 3 and 4 adverse events. RESULTS Four randomized controlled trials (N = 590 patients) were included. Platinum-based chemotherapy significantly increased the objective response rates from 43.1% to 62.7% (odds ratio 2.34, 95% confidence interval 1.66-3.28, P < 0.001). Three randomized controlled trials (N = 414 patients) reported survival outcomes. Patients administered platinum-based regimens showed significantly longer progression-free survival (hazard ratio 0.55, 95% confidence interval 0.37-0.82, P = 0.004) and a nonsignificant trend toward improved overall survival (hazard ratio 0.76, 95% confidence interval 0.57-1.00, P = 0.05). Only 2 studies reported the rates of grade 3 and 4 adverse events; grade 3-4 thrombocytopenia was more commonly associated with platinum-based chemotherapy (odds ratio 7.54, 95% confidence interval 1.37-41.60, P = 0.02) and grade 3-4 fatigue with platinum-free chemotherapy (odds ratio 0.23, 95% confidence interval 0.08-0.68, P = 0.008). CONCLUSIONS First-line platinum-based chemotherapy was associated with significantly increased objective response rates, longer progression-free survival, and a nonsignificant trend toward improved overall survival in patients with metastatic triple-negative breast cancer at the high risk of grade 3-4 thrombocytopenia.

Comparison of capecitabine-based regimens with platinum-based regimens in Chinese triple-negative breast cancer patients with liver metastasis. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:109. [PMID: 33569411 PMCID: PMC7867954 DOI: 10.21037/atm-20-4590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/06/2022]
Abstract
Background Capecitabine-based chemotherapy (CBC) presents potential value in patients with liver metastasis; platinum-based chemotherapy (PBC) has shown promising benefit in patients with triple-negative breast cancer (TNBC). For TNBC patients with liver metastasis, which treatment strategy is better remains to be further studied. The aim of this study was to report the first real-world data evaluating the efficacy and safety of PBC versus CBC in the first-line treatment in Chinese TNBC patients with liver metastasis. Methods TNBC patients with liver metastasis pretreated with anthracyclines/taxanes in 4 institutions of China between January 2010 and December 2019 were included. Objective response rate (ORR), overall survival, treatment pattern, and toxicity profile were assessed between PBC and CBC groups. Results A total of 59 TNBC patients with liver metastasis were identified. Among these, 33 were treated with PBC and 26 were treated with CBC. The ORR was higher in the CBC group than in the PBC group (57.7% versus 30.3%, P=0.035). Median overall survival was also greatly improved (19.2 versus 14.4 months, P=0.041). Docetaxel/cisplatin was more likely to be used for PBC, and paclitaxel/capecitabine was the main regimen for CBC. Multivariable Cox regression analysis indicated that CBC was an independent predictor for overall survival after adjustment for baseline factors including age, tumor size, nodal status, prior anthracyclines/taxanes use, and tumor grade (odds ratio =0.51; 95% confidence interval, 0.27-0.98; P=0.042). Adverse events were not different except gastrointestinal tract toxicities, hand-foot syndrome and hematologic toxicity. Conclusions For TNBC patients with liver metastasis, capecitabin-based chemotherapy might be more suitable than the platinum-based regimen in the first-line treatment, as measured by objective response rate and overall survival. Further large-scale studies are warranted.

Korean J Intern Med 2021; 36:182-193.

Abstract
BACKGROUND/AIMS Sequential monotherapy is recommended for anthracycline-and taxane-resistant metastatic breast cancer (MBC), but combination chemotherapy is considered in patients with visceral crisis. Cisplatin-doublet chemotherapy is a combination regimen for MBC, but prolonged treatment is challenging because of toxicity. We analyzed the role of single-agent maintenance chemotherapy after cisplatin-doublet chemotherapy for MBC. METHODS From January 2011 to December 2017, 96 anthracycline- and taxane- resistant MBC patients were retrospectively reviewed, and 49 patients with a sustained clinical benefit during the initial 6 cycles of cisplatin-doublet chemotherapy were enrolled for study. Patients were treated with gemcitabine-cisplatin (gemcitabine, 1,250 mg/m2, intravenously [IV], days 1 to 8; cisplatin 60 mg/m2, IV, day 1) or capecitabine-cisplatin (capecitabine 2,500 mg/m2, orally, days 1 to 14; cisplatin 60 mg/m2, IV, day 1) during the induction period. After 6 cycles, 16 patients were switched to single-maintenance treatment (gemcitabine or capecitabine) and the doublet regimen was continued in 24 patients. Survival outcomes (progression- free survival [PFS] and overall survival [OS]) were analyzed. RESULTS Among the 49 patients who showed a clinical benefit during cisplatin- doublet therapy, 24 were maintained on the doublet regimen, 16 were switched to single-maintenance treatment, and chemotherapy was suspended until disease progression in nine patients. The single-maintenance chemotherapy group showed superior survival than the chemotherapy holiday and doublet regimen groups (median PFS 15.43 months vs. 8.37 and 10.67 months, respectively, p = 0.008; median OS 43.67 months vs. 22.17 and 22.33 months, respectively, p = 0.014). CONCLUSION Patients showing a clinical benefit during 6 cisplatin-doublet chemotherapy cycles may have a sustained survival benefit from single-maintenance chemotherapy.

Birinapant Enhances Gemcitabine's Antitumor Efficacy in Triple-Negative Breast Cancer by Inducing Intrinsic Pathway-Dependent Apoptosis. Mol Cancer Ther 2020; 20:296-306. [PMID: 33323457 DOI: 10.1158/1535-7163.mct-19-1160] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Revised: 09/01/2020] [Accepted: 11/30/2020] [Indexed: 11/16/2022]
Abstract
Triple-negative breast cancer (TNBC) is the most aggressive subgroup of breast cancer, and patients with TNBC have few therapeutic options. Apoptosis resistance is a hallmark of human cancer, and apoptosis regulators have been targeted for drug development for cancer treatment. One class of apoptosis regulators is the inhibitors of apoptosis proteins (IAPs). Dysregulated IAP expression has been reported in many cancers, including breast cancer, and has been shown to be responsible for resistance to chemotherapy. Therefore, IAPs have become attractive molecular targets for cancer treatment. Here, we first investigated the antitumor efficacy of birinapant (TL32711), a biindole-based bivalent mimetic of second mitochondria-derived activator of caspases (SMACs), in TNBC. We found that birinapant as a single agent has differential antiproliferation effects in TNBC cells. We next assessed whether birinapant has a synergistic effect with commonly used anticancer drugs, including entinostat (class I histone deacetylase inhibitor), cisplatin, paclitaxel, voxtalisib (PI3K inhibitor), dasatinib (Src inhibitor), erlotinib (EGFR inhibitor), and gemcitabine, in TNBC. Among these tested drugs, gemcitabine showed a strong synergistic effect with birinapant. Birinapant significantly enhanced the antitumor activity of gemcitabine in TNBC both in vitro and in xenograft mouse models through activation of the intrinsic apoptosis pathway via degradation of cIAP2 and XIAP, leading to apoptotic cell death. Our findings demonstrate the therapeutic potential of birinapant to enhance the antitumor efficacy of gemcitabine in TNBC by targeting the IAP family of proteins.

Localized Delivery of Cisplatin to Cervical Cancer Improves Its Therapeutic Efficacy and Minimizes Its Side Effect Profile. Int J Radiat Oncol Biol Phys 2020; 109:1483-1494. [PMID: 33253820 DOI: 10.1016/j.ijrobp.2020.11.052] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 11/09/2020] [Accepted: 11/20/2020] [Indexed: 01/16/2023]
Abstract
PURPOSE Cervical cancer represents the fourth most frequent malignancy in the world among women, and mortality has remained stable for the past 4 decades. Intravenous cisplatin with concurrent radiation therapy is the standard-of-care for patients with local and regional cervical cancer. However, cisplatin induces serious dose-limiting systemic toxicities and recurrence frequently occurs. In this study, we aimed to develop an intracervical drug delivery system that allows cisplatin release directly into the tumor and minimize systemic side effects. METHODS AND MATERIALS Twenty patient biopsies and 5 cell lines treated with cisplatin were analyzed for platinum content using inductively coupled plasma mass spectrometry. Polymeric implants loaded with cisplatin were developed and evaluated for degradation and drug release. The effect of local or systemic cisplatin delivery on drug biodistribution as well as tumor burden were evaluated in vivo, in combination with radiation therapy. RESULTS Platinum levels in patient biopsies were 6-fold lower than the levels needed for efficacy and radiosensitization in vitro. Cisplatin local delivery implant remarkably improved drug specificity to the tumor and significantly decreased accumulation in the blood, kidney, and other distant normal organs, compared with traditional systemic delivery. The localized treatment further resulted in complete inhibition of tumor growth. CONCLUSIONS The current standard-of-care systemic administration of cisplatin provides a subtherapeutic dose. We developed a polymeric drug delivery system that delivered high doses of cisplatin directly into the cervical tumor, while lowering drug accumulation and consequent side effects in normal tissues. Moving forward, these data will be used as the basis of a future first-in-human clinical trial to test the efficacy of localized cisplatin as adjuvant or neoadjuvant chemotherapy in local and regional cervical cancer.

Abstract
Development of new research, classification, and therapeutic options are urgently required due to the fact that TNBC is a heterogeneous malignancy. The expression of high molecular weight cytokeratins identifies a biologically and clinically distinct subgroup of TNBCs with a basal-like phenotype, representing about 75% of TNBCs, while the remaining 25% includes all other intrinsic subtypes. The triple negative phenotype in basal-like breast cancer (BLBC) makes it unresponsive to endocrine therapy, i.e., tamoxifen, aromatase inhibitors, and/or anti-HER2-targeted therapies; for this reason, only chemotherapy can be considered an approach available for systemic treatment even if it shows poor prognosis. Therefore, treatment for these subgroups of patients is a strong challenge for oncologists due to disease heterogeneity and the absence of unambiguous molecular targets. Dysregulation of the cellular miRNAome has been related to huge cellular process deregulations underlying human malignancy. Consequently, epigenetics is a field of great promise in cancer research. Increasing evidence suggests that specific miRNA clusters/signatures might be of clinical utility in TNBCs with basal-like phenotype. The epigenetic mechanisms behind tumorigenesis enable progress in the treatment, diagnosis, and prevention of cancer. This review intends to summarize the epigenetic findings related to miRNAome in TNBCs with basal-like phenotype.

Abstract
Fingolimod represses triple negative breast cancer cells survival in vitro by inducing cell apoptosis. Fingolimod represses triple negative breast cancer progression in orthotopic graft murine in vivo models. Fingolimod represses spleen and liver metastases without affecting lung metastasis in murine in vivo models. In contrast with Cisplatin, Fingolimod is well tolerated in murine in vivo models.
Surgery followed by a chemotherapy agent is the first-line treatment for breast cancer patients. Nevertheless, new targets are required for women with triple-negative breast cancer (TNBC) in order to improve the treatment of this aggressive cancer subtype. Multiple pro-inflammatory molecules including lipid-based substances such as sphingosine-1-phosphate (S1P) promote cancer progression. In this preclinical study, we aim to investigate the efficacy of Fingolimod, an inhibitor of S1P / S1P receptors axis, already approved as an immunomodulator in multiple sclerosis. The impact of Fingolimod was analyzed using in vitro 2D and 3D cell survival analysis and in vivo orthotopic graft models, using mouse and human TNBC cells implanted in immunocompetent or immunodeficient mice, respectively. Resection of the tumor primary mass was also performed to mimic the clinical standard of care. We demonstrated that Fingolimod repressed tumor cell survival in vitro. We also showed in preclinical mouse TNBC models that Fingolimod repressed tumor progression and liver and spleen metastases without apparent adverse effects on the animals. Our data indicate that Fingolimod induces tumor cells apoptosis and thereby represses tumor progression. Globally, our data suggest that Fingolimod merits further evaluation as a potential therapeutic opportunity for TNBC.

Abstract
Background In order to offer optimal treatment approaches based on available evidence, the Commission Breast of the Working Group Gynecologic Oncology (AGO) of the German Cancer Society developed therapy algorithms for eight complex treatment situations in primary and advanced breast cancer. Summary Therapy algorithms for the following complex treatment situations are outlined in this paper: (neo)adjuvant therapy of human epidermal growth factor receptor 2 (HER2)-positive breast cancer; axillary surgery and neoadjuvant chemotherapy; adjuvant endocrine therapy in premenopausal patients; adjuvant endocrine therapy in postmenopausal patients; hormone receptor (HR)-positive/HER2-negative metastatic breast cancer: strategies; HR-positive/HER2-negative metastatic breast cancer: endocrine-based first-line treatment; HER2-positive metastatic breast cancer: first to third-line; metastatic triple-negative breast cancer. Key Messages The therapy options shown in these algorithms are based on the current AGO recommendations updated in January 2020 but cannot represent all evidence-based treatment options. Prior therapies, performance status, comorbidities, patient preference, etc. must be taken into account for the actual treatment choice. Therefore, in individual cases, other evidence-based treatment options not listed here may also be appropriate and justified.

Targeting SKA3 suppresses the proliferation and chemoresistance of laryngeal squamous cell carcinoma via impairing PLK1-AKT axis-mediated glycolysis. Cell Death Dis 2020; 11:919.

Abstract
Spindle and kinetochore-associated complex subunit 3 (SKA3) is a well-known regulator of chromosome separation and cell division, which plays an important role in cell proliferation. However, the mechanism of SKA3 regulating tumor proliferation via reprogramming metabolism is unknown. Here, SKA3 is identified as an oncogene in laryngeal squamous cell carcinoma (LSCC), and high levels of SKA3 are closely associated with malignant progression and poor prognosis. In vitro and in vivo experiments demonstrate that SKA3 promotes LSCC cell proliferation and chemoresistance through a novel role of reprogramming glycolytic metabolism. Further studies reveal the downstream mechanisms of SKA3, which can bind and stabilize polo-like kinase 1 (PLK1) protein via suppressing ubiquitin-mediated degradation. The accumulation of PLK1 activates AKT and thus upregulates glycolytic enzymes HK2, PFKFB3, and PDK1, resulting in enhancement of glycolysis. Furthermore, our data reveal that phosphorylation at Thr360 of SKA3 is critical for its binding to PLK1 and the increase in glycolysis. Collectively, the novel oncogenic signal axis "SKA3-PLK1-AKT" plays a critical role in the glycolysis of LSCC. SKA3 may serve as a prognostic biomarker and therapeutic target, providing a potential strategy for proliferation inhibition and chemosensitization in tumors, especially for LSCC patients with PLK1 inhibitor resistance.

Abstract
BACKGROUND In a previous Cochrane Review, we found that for women with metastatic breast cancer unselected for triple-negative disease, there is little or no survival benefit and excess toxicity from platinum-based regimens. In subgroup analyses, however, we found preliminary low-quality evidence of a survival benefit from platinum-based regimens for women with metastatic triple-negative breast cancer (mTNBC). This review updates the evidence from the mTNBC subgroup analyses in the previous Cochrane Review. OBJECTIVES To assess the effects of platinum-containing chemotherapy regimens with regimens not containing platinum in the management of women with mTNBC. SEARCH METHODS We obtained relevant studies published prior to 2015 and their extracted results from the mTNBC subgroup analysis in the previous Cochrane Review. We searched the Cochrane Breast Cancer Group's Specialised Register, CENTRAL, MEDLINE, Embase, the World Health Organization's International Clinical Trials Registry Platform and ClinicalTrials.gov between 2015 and 27 September 2019. We identified further potentially relevant studies from previous trial reports, systematic reviews, and meta-analyses. SELECTION CRITERIA Randomised trials comparing platinum-containing chemotherapy regimens with regimens not containing platinum in women with mTNBC. Individual trials could compare one or more platinum-based regimens to one or more non-platinum regimens; hence there could be more 'treatment-comparisons' (i.e. platinum regimen versus non-platinum regimen comparison) than trials. Trial participants may have been purposely selected for mTNBC or inadvertently selected as a subgroup. DATA COLLECTION AND ANALYSIS At least two independent reviewers assessed studies for eligibility and quality, and extracted all relevant data from each study. We derived hazard ratios (HRs) for time-to-event outcomes, where possible, and used fixed-effect models for meta-analyses. We analysed objective tumour response rates (OTRRs) and toxicities as binary (dichotomous) outcomes with risk ratios (RRs) used as measures of effects. We extracted quality of life data, if available. We used GRADE to rate the quality of evidence for time-to-event and tumour response outcomes. MAIN RESULTS This review includes 13 treatment-comparisons involving 1349 women from 10 studies. Twelve of the 13 treatment-comparisons were included in one or more meta-analyses. Of the 13 treatment-comparisons, six and eight had published or provided time-to-event data on overall survival (OS) or progression-free survival/time to progression (PFS/TTP), respectively, that could be included in meta-analyses. Ten treatment-comparisons published or provided OTRR data that could be included in meta-analyses. Eight of the 13 treatment-comparisons were from studies that selected participants on the basis of mTNBC status, while the other five treatment-comparisons were from studies that reported mTNBC results as part of subgroup analyses. Analysis of six treatment-comparisons indicated that platinum-containing regimens may have provided a small survival benefit to mTNBC patients (HR 0.85, 95% CI 0.73 to 1.00; 958 women; moderate-quality evidence) with no evidence of heterogeneity (P = 0.41; I2 = 1%). Data from eight treatment-comparisons showed that platinum regimens may improve PFS/TTP (HR 0.77, 95% CI 0.68 to 0.88; 1077 women; very low-quality evidence). There was marked evidence of heterogeneity (P < 0.0001; I2 = 80%). There was also low-quality evidence of better tumour response for platinum recipients (RR 1.40, 95% CI 1.22 to 1.59; 1205 women) with some evidence of heterogeneity (P = 0.01; I2 = 58%). The observed heterogeneity for the PFS/TTP and OTRR outcomes may reflect between-study differences and general difficulties in assessing tumour response, as well as the varying potencies of the comparators. Compared with women receiving non-platinum regimens: rates of grade 3 and 4 nausea/vomiting were higher for platinum recipients (RR 4.77, 95% CI 1.93 to 11.81; 655 women; low-quality evidence) and rates of grade 3 and 4 anaemia were higher for platinum recipients (RR 3.80, 95% CI 2.25 to 6.42; 843 women; low-quality evidence). In general, however, relatively few intervention-comparisons could be included in meta-analyses for adverse events. None of the studies reported quality of life. AUTHORS' CONCLUSIONS For women with mTNBC, there was moderate-quality evidence of a small survival benefit from platinum-based regimens compared to non-platinum regimens. This finding is consistent with findings of a PFS/TTP benefit and improved tumour response from platinum-based regimens. These potential benefits, however, should be weighed against previously identified excess toxicities from platinum-based regimens, particularly regimens containing cisplatin. Further randomised trials of platinum-based regimens among women with mTNBC are required.

Abstract
PURPOSE To evaluate the incidence risk of programmed cell death-1/programmed cell death ligand 1 (PD-1/PD-L1) inhibitor-related alopecia for cancer patients, the meta-analysis was put into practice. METHOD The meta-analysis was designed and put into practice according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. RESULTS After rigorous screening and verification, 22 clinical trials involving PD-1/PD-L1 inhibitors were collected for the final comprehensive analysis. The incidence risk of alopecia for all-grade in the PD-1/PD-L1 group was significantly lower than that in the control chemotherapy group (odds ratio [OR] = 0.01, 95% confidence interval [CI]: [0.01, 0.04], I = 86%, Z = 8.73 [P < .00001]). Similar to the above, the incidence risk of alopecia for grade 3-5 related to PD-1/PD-L1 was obvious lower than the control group (OR = 0.17, 95% CI:[0.05, 0.55], I = 0%, Z = 2.97 [P = .003]). When 7 clinical trials (PD-1/PD-L1 + Chemotherapy vs Chemotherapy) were taken to evaluate the risk of alopecia for all-grade and grade 3-5, no statistically significant results were found. CONCLUSION The incidence risk of alopecia caused by PD-1/PD-L1 is significantly lower than chemotherapy, and there is no statistical significant evidence that PD-1/PD-L1 combined with chemotherapy would increase the incidence risk of alopecia.

Abstract
Liposomes (LPs) as promising drug delivery systems are widely applied in cancer therapy. This study aimed to investigate the effect of glypican-1 (GPC1)-targeted and gemcitabine (GEM)-loaded LP [GPC1-LP (GEM)] on cell proliferation and apoptosis in PANC-1s, as well as on orthotopic pancreatic cancer (PDAC) mice. The GPC1-LP (GEM) and LP (GEM) was prepared, and then the size distribution of GPC1-LP (GEM) was analyzed by dynamic light scattering (DLS). In vitro drug release assay of GPC1-LP (GEM) and LP (GEM) was performed, and the expression of GPC1 in PANC1 cells was detected as well. Next, the effects of free GEM, LP (GEM) and GPC1-LP (GEM) on cell viability, clone number, and apoptosis, as well as the expression of proteins associated with apoptosis were measured in 239T and PANC-1 cells. Furthermore, the body weight and tumor size of orthotopic PDAC mice were evaluated following the treatment of free GEM, LP (GEM) or GPC1-LP (GEM). LP (GEM) and GPC1-LP (GEM) were successfully prepared with a successful GEM release within 24 h. In addition, GPC1 was positively expressed in PANC-1 cells but not 293T cells. These findings provided more insights into the anti-tumor potential for the biomedical application of GPC1-LP (GEM) in PDAC.

Abstract
Abstract Taxanes represented by paclitaxel and targeted therapy including trastuzumab are two common agents for human epidermal growth factor receptor-2 (HER-2)-positive breast cancer patients. Effectiveness, however, usually comes at the cost of many side effects, some of
which are even fatal. Drug-induced interstitial lung diseases (DILDs) comprise a group of drug-induced pulmonary injuries usually caused by using these medications. For DILDs, systemic therapy can be harmful to lung tissues and rapidly threaten the lives of some breast cancer patients. Through
the cases from our hospital and related studies in medical databases, we hope readers can learn a lesson from an angle of multi-disciplinary integration based on clinical practice and pharmacological mechanisms to make anti-cancer agents less harmful and reduce the incidence of DILD in breast
cancer patients during systemic therapy.

Abstract
INTRODUCTION This study aimed to evaluate the cost-effectiveness of cisplatin plus gemcitabine vs. paclitaxel plus gemcitabine as a first-line treatment for metastatic triple-negative breast cancer in China. METHODS The Markov model and partitioned survival (PS) model were used, and the study included three health states over the period of a lifetime. Transition probabilities and safety data were derived from the CBCSG006 trial (cisplatin plus gemcitabine vs. paclitaxel plus gemcitabine in patients who had acquired metastatic triple-negative breast cancer). Cost and utility values were derived from previous studies, the Chinese Drug Bidding Database, and healthcare documents. Sensitivity analyses were performed to observe model stability. RESULTS In the Markov model, compared with paclitaxel plus gemcitabine, cisplatin plus gemcitabine yielded an additional 0.15 QALYs, with an incremental cost of 1976.33 USD. The incremental cost-utility ratio (ICUR) was 12,826.98 USD/QALY (quality-adjusted life year). In the PS model, cisplatin plus gemcitabine yielded an additional 0.17 QALYs with an incremental cost of 2384.63 USD; the incremental cost-utility ratio (ICUR) was 13,867.7 USD/QALY. In the first scenario analysis, in which the 3-year time horizon was used in both arms, the total QALYs in the cisplatin plus gemcitabine group were larger and the costs were lower, indicating that cisplatin plus gemcitabine was superior to paclitaxel plus gemcitabine. In the second scenario, in which the progression-free (PF) utility (during chemotherapy) was 0.76, the PF utility was 0.96, and the post-progression (PP) utility was 0.55, the result obtained with the Markov model showed that the ICUR was 11,063.68 USD/QALY. In the probabilistic sensitivity analysis (PSA) on the Markov model, the probabilities that cisplatin plus gemcitabine would be cost-effective were 48.94-78.72% if the willingness-to-pay threshold was 9776.8 to 29,330.4 USD/QALY. CONCLUSIONS The findings of the present analysis suggest that cisplatin plus gemcitabine might be much more cost-effective than paclitaxel plus gemcitabine in patients receiving first-line treatment for metastatic triple-negative breast cancer in China.

[PMID: 32710659 DOI: 10.1002/cncr.32848] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Revised: 01/25/2020] [Accepted: 02/26/2020] [Indexed: 02/03/2023]
Abstract
With rapid advancement in clinical research, clinical trials on breast cancer in China have made great progress and are increasingly receiving worldwide recognition. Oncologists have been provided with an unprecedented opportunity to conduct clinical trials that offer both advantages and challenges. Investigator-initiated trials (IITs) and trials on domestic innovative drugs are still in the initial stages, with plenty of room to grow. The goal of this study was to systematically review time trends of the changing landscape of clinical drug development in China over the course of the last decade (from 2009 to 2018). The number of clinical trials specific to breast cancer has increased in a span of 10 years, from 36 trials in 2009 to 113 in 2018, and this trend is accompanied by an increase in publications, from 13 in 2009 to 52 in 2015. A total of 593 trials were conducted in breast cancer between 2009 and 2018. The distribution pattern of trial phases shows that phase 2 trials accounted for 34% of the total, followed by phase 3 trials at 21% and phase 1 trials at 20%. Academic trials or IITs were found to be the major sponsors, with 52% of trials being sponsored by them followed by pharmaceutical companies as a secondary sponsor (38%). Additionally, trials on chemotherapeutic agents constituted 50% of the trials followed by trials on targeted therapy (31%). The review provides insight on the effectiveness of the pharmaceutical industry and identify unmet clinical needs of stakeholders. With accumulated experience of Chinese oncologists and increasing support from the Chinese government, greater success could be anticipated in the near future.

Platinum-based chemotherapy in advanced triple-negative breast cancer: A multicenter real-world study in China. Int J Cancer 2020; 147:3490-3499. [PMID: 32588429 DOI: 10.1002/ijc.33175] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Revised: 05/21/2020] [Accepted: 05/25/2020] [Indexed: 11/11/2022]
Abstract
Platinum-based chemotherapy (PBC) has proven benefits in phase III studies for advanced triple-negative breast cancer (TNBC) patients; however, real-world data of large samples from multiple centers are lacking. Our study was to compare the effectiveness of PBC and non-PBC in advanced TNBC patients in multicenter real-world settings. Totally, 495 patients with advanced TNBC receiving PBC (n = 350) or non-PBC (n = 145) at four cancer centers in China between 2003 and 2019 were included. Treatment responses and outcomes were compared between the two groups from first-line to third-line treatment. Of patients with PBC, 249 (71.1%) received PBC from first-line chemotherapy, 86 (24.6%) from second-line and 15 (4.3%) from third-line treatment. In first-line treatment, PBC was superior to non-PBC in objective response rate (ORR, 53.0% vs 32.1%, P < .001) and median progression-free survival (PFS, 8.4 vs 6.0 months, P = .022), whereas overall survival (OS) was similar (19.2 vs 16.8 months, P = .439). When comparing patients receiving non-PBC doublets (n = 221) with those receiving PBC doublets (n = 249), the same trend was observed in ORR (32.6% vs 53.0%, P < .001), median first-line PFS (6.5 vs 8.4 months, P = .041) and median first-line OS(17.8 vs 19.2 months, P = .568). Paclitaxel/docetaxel + platinum was more likely to be used, followed by gemcitabine + platinum. In second/third-line treatment, PBC yielded a similar response and survival compared to non-PBC. Adding PBC in the first-line therapy was better than that in the latter-line of treatment in terms of ORR, PFS and OS (P < .001). Toxic effects of PBC were tolerable and the most common adverse event was neutropenia (38.6%). PBC doublets exhibited superior efficacy and manageable toxicity compared to non-PBC doublets in the first-line treatment for Chinese mTNBC patients.

Abstract
Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer with a heterogeneous genetic profile. Chemotherapy exhibits substantial activity in a small subset of these patients. Drug resistance is inevitable. Major progress has been made in the genetic analysis of TNBC to identify novel targets and increase the precision of therapeutic intervention. Such progress has translated into major advances in treatment strategies, including modified chemotherapy approaches, immune checkpoint inhibitors, and targeted therapeutic drugs. All of these strategies have been evaluated in clinical trials. Nevertheless, patient selection remains a considerable challenge in clinical practice.

Abstract
Development of targeted therapies for triple-negative breast cancer (TNBC) is an unmet medical need. Cisplatin has demonstrated its promising potential for the treatment of TNBC in clinical trials; however, cisplatin treatment is associated with hypoxia that, in turn, promotes cancer stem cell (CSC) enrichment and drug resistance. Therapeutic approaches to attenuate this may lead to increased cisplatin efficacy in the clinic for the treatment of TNBC. In this report we analyzed clinical datasets of TNBC and found that TNBC patients possessed higher levels of EGFR and hypoxia gene expression. A similar expression pattern was also observed in cisplatin-resistant ovarian cancer cells. We, thus, developed a new therapeutic approach to inhibit EGFR and hypoxia by combination treatment with metformin and gefitinib that sensitized TNBC cells to cisplatin and led to the inhibition of both CD44+/CD24− and ALDH+ CSCs. We demonstrated a similar inhibition efficacy on organotypic cultures of TNBC patient samples ex vivo. Since these drugs have already been used frequently in the clinic; this study illustrates a novel, clinically translatable therapeutic approach to treat patients with TNBC.

Abstract
Triple-negative breast cancer (TNBC) remains the most aggressive cluster of all breast cancers, which is due to its rapid progression, high probabilities of early recurrence, and distant metastasis resistant to standard treatment. Following the advances in cancer genomics and transcriptomics that can illustrate the comprehensive profiling of this heterogeneous disease, it is now possible to identify different subclasses of TNBC according to both intrinsic signals and extrinsic microenvironment, which have a huge influence on predicting response to established therapies and picking up novel therapeutic targets for each cluster. In this review, we summarize basic characteristics and critical subtyping systems of TNBC, and particularly discuss newly found prospective targets and relevant medications, which were proved promising in clinical trials, thus shedding light on the future development of precision treatment strategies.

Abstract
Gemcitabine (GEM) resistance in pancreatic adenocarcinoma mediated by the receptor for advanced glycation end products (RAGE) has been demonstrated. Therefore, investigating the safety and the potential of new auxiliary methods for pancreatic cancer treatment is urgent. Ursolic acid (UA), a natural pentacyclic triterpenoid found in apple peels, rosemary, and thyme, has been reported to have anticancer capacity. This study aimed to reveal the underlying mechanisms of UA in cell death and drug enhancement, especially in GEM-resistant pancreatic cancer cells. First, GEM-resistant cells (MIA Paca-2GEMR cells) were established by incrementally increasing GEM culture concentrations. UA treatment reduced cell viability through cell cycle arrest and endoplasmic reticulum (ER) stress, resulting in apoptosis and autophagy in a dose-dependent manner in MIA Paca-2 and MIA Paca-2GEMR cells. High RAGE expression in MIA Paca-2GEMR cells was suppressed by UA treatment. Interestingly, knocking down RAGE expression showed similar UA-induced effects in both cell lines. Remarkably, UA had a drug-enhancing effect by decreasing cell viability and increasing cell cytotoxicity when combined with GEM treatment. In conclusions, UA triggered ER stress, subsequently regulating apoptosis- and autophagy-related pathways and increasing GEM chemosensitivity in pancreatic cancer cells by inhibiting the expression of RAGE.
