Abstract
Prodiginines have been studied extensively for their anticancer activity, however, the majority of the research has focused on prodigiosin. In this study, cycloheptylprodigiosin (S-1) is extracted from marine bacterium Spartinivicinus ruber MCCC 1K03745T, and its anticancer property was investigated. It exhibits remarkable cytotoxicity against a panel of human lung cancer cell lines, with the IC50 values ranging from 84.89 nM to 661.2 nM. After 6 h of treatment, S-1 gradually accumulates on mitochondria and lysosomes. While lower doses of S-1 induce cell cycle arrest, treatment with higher doses results in cell death in apoptotic independent manner in both NCI-H1299 and NCI-H460 cell lines. Interestingly, treatment with S-1 leads to the accumulation of LC3B-II via pathways that vary among different cell lines. In addition to its role as an autophagy inhibitor, S-1 also promotes autophagy initiation as demonstrated by the increment of EGFP fragment in the EGFP-LC3 degradation assay, however, inhibition of autophagy does not rescue cells from death induced by S-1. Mechanistically, S-1 impairs autophagic flux through disrupting acidic lysosomal pH and blocking the maturation of cathepsin D. Moreover, treatment with S-1 enhanced secretion of both pro- and mature forms of cathepsin D, coincident with disintegration of trans-Golgi network. Interestingly, S-1 does not induce ferroptosis, pyroptosis or necroptosis in NCI-H1299 cells. However, treatment of NCI-H460 cells with S-1 induces methuosis, which can be suppressed by Rac1 inhibitor EHT 1864. Our data demonstrate that S-1 is an effective anticancer agent with potential therapeutic application.

Front Oncol 2023; 13:1091488. [PMID: 36923423 PMCID: PMC10009168 DOI: 10.3389/fonc.2023.1091488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 02/09/2023] [Indexed: 03/02/2023] Open
Abstract
Background The current exploration of the tumor immune microenvironment is enthusiastic, but few studies explored the impact of angiogenesis on the immune microenvironment. Immunotherapy combined with anti-angiogenesis therapy has become one of the first-line treatment for lung adenocarcinoma. Our study aimed to explore the reasons for resistance of immunotherapy, and explore markers for immunotherapy combined with anti-angiogenesis therapy. Methods First, by unsupervised clustering of 36 angiogenesis-related genes in lung adenocarcinoma patients from TCGA database, AGS1 and AGS2 groups were distinguished with significantly different clinical outcomes. Secondly, the immune microenvironment and metabolic characteristics were analyzed. Next, we used the GDSC and GEO database to analyze therapeutic responses. Then, through multivariate Cox regression, the hub gene: JAG1, significantly related to prognosis was selected, and further verified by multi-omics data. Finally, we validated that patient with high JAG1 expression had a low immune-infiltrating tumor microenvironment through single-cell transcriptomic data. Results Compared with the AGS1 group, AGS2 showed an immune "cold" phenotype with lower lymphocyte infiltration, and was associated with worse prognoses. At the same time, the immunosuppressive TGF-β response was significantly higher in AGS2. Furthermore, the glycolysis ability of the AGS2 was stronger than AGS1. The expression of JAG1 was significantly higher in the AGS2, and was significantly negatively correlated with the degree of immune infiltration, accompanying with higher glycolytic capacity. The above results indicate that patients with high expression of JAG1 may lead to immunosuppressive phenotype due to its strong glycolytic capacity, thus making immunotherapy resistance. Conclusion Patients with high expression of JAG1 enhanced glycolytic capacity was likely to cause suppressed immune microenvironment. JAG1 may be a marker for resistance of immunotherapy. Combining anti-angiogenesis therapy could be considered to improve the prognosis of those patients.

Abstract
Background This study aimed to evaluate for the first time whether certain genetic and
clinical factors could serve as minimally invasive predictors of survival
and toxicity to platinum-based chemotherapy in advanced lung
adenocarcinoma. Methods The study included 121 advanced lung adenocarcinoma patients treated with
platinum-based dublets until progression or unacceptable toxicity. Response
was evaluated using standard radiological methods and toxicity graded
according to the Common Terminology Criteria for Adverse Events (CTCAE)
v5.0. Genotyping was performed using PCR-RFLP. Statistical significance was
set at P < .05. Results No significant influence of the examined polymorphisms on the occurrence of
high-grade toxicity was detected. However, TP53 72Pro allele carriers were
more prone to nausea (P = .037) and thrombocytopenia (P = .051). Anemia and
neuropathy occurred more frequently in XRCC1 399Arg allele carriers (Pearson
χ2 test, P = .025 and P = .004 respectively). RAD51 135CC carriers were
significantly more prone to neutropenia (P = .027). Conclusions A set of easily determined genetic and clinical predictors of survival and
specific toxicity profiles of platinum-based chemotherapy in advanced lung
adenocarcinoma were determined in this study, which might be useful for the
construction of population-specific, time- and cost-efficient prognostic and
predictive algorithms.

Abstract
Background Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related mortality worldwide. It is advisable to select the appropriate treatment based on characteristics of the cancer such as pathology, mutations, and programmed death‐ligand 1 (PD‐L1) levels. In this study, by remarking squamous NSCLC with low PD‐L1 expression without mutations, we investigated the efficacy and safety of regimens that included molecularly targeted drugs such as immune checkpoint inhibitors (ICIs) through a network meta‐analysis. Methods Databases were searched systematically to identify appropriate articles, in which randomized trials with incurable squamous NSCLC were described. Suitable studies were manually checked by two reviewers. A random model network meta‐analysis was conducted, in which the primary outcome was the overall survival rate. Results We identified 48 studies, which included 16 391 patients. When a platinum + third‐generation cytotoxic agent regimen (platinum regimen) was a reference, the platinum regimen + pembrolizumab (Pemb) yielded the best results in regard to the overall survival rate when compared with chemotherapy (hazard ratio [HR] = 0.57, 95% confidence interval [CI] = 0.36–0.90, p = 0.016) followed by the platinum regimen + nivolumab (Niv) + ipilimumab (Ipi) (HR = 0.61, 95% CI = 0.44–0.84, p = 0.003). However, the efficacy of ICI monotherapy was not statistically different from that of the platinum regimen. Conclusions The combination therapies, which were the platinum regimen + Pemb and the platinum regimen + Niv + Ipi, rather than ICI monotherapy were effective first‐line agents for treating squamous NSCLC with low PD‐L1 levels.

Abstract
Background Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. There is a rank order of the efficacy and safety of treatment options, including immune checkpoint inhibitors (ICIs), bevacizumab (Bev), and cytotoxic drugs. When patients have low programmed death-ligand 1 (PD-L1) expression, there are multiple options for treatment. In this study, we focused on ICI regimens in patients with non-squamous NSCLC with low PD-L1 expression and no driver alterations and assessed the efficacy of the regimens using network meta-analysis. Methods Randomized trials for incurable chemo-naïve non-squamous NSCLC were collected through electronic searches. The data were independently extracted and cross-checked by two investigators. The primary outcome of this analysis was overall survival (OS). A frequentist weighted least-squares approach random-model network meta-analysis was applied. Results Sixty-eight eligible studies and 22,619 patients were identified. Using a platinum + third-generation cytotoxic agent regimen (platinum regimen) as a reference, the platinum regimen + pembrolizumab (Pemb) [hazard ratio (HR) =0.55, 95% confidence interval (CI): 0.34–0.89, P=0.015] showed the best OS, followed by the platinum regimen + nivolumab (Niv) + ipilimumab (Ipi) (HR =0.61, 95% CI: 0.44–0.84, P=0.003) with no heterogeneity (I2=0%, P=0.348). Conclusions The addition of Pemb or Niv/Ipi to platinum-based chemotherapy seems to be a good therapeutic option for non-squamous NSCLC with a PD-L1 tumor proportion score (TPS) of 1–49%.

Abstract
Non-small cell lung cancer (NSCLC) is a major subtype of lung cancer that accounts for almost 85% of lung cancer cases worldwide. Although recent advances in chemotherapy, radiotherapy, and immunotherapy have helped in the clinical management of these patients, the survival rate in advanced stages remains dismal. Furthermore, there is a critical lack of accurate prognostic and stratification markers for emerging immunotherapies. To harness immune response modalities for therapeutic benefits, a detailed understanding of the immune cells in the complex tumor microenvironment (TME) is required. Among the diverse immune cells, natural killer (NK cells) and dendritic cells (DCs) have generated tremendous interest in the scientific community. NK cells play a critical role in tumor immunosurveillance by directly killing malignant cells. DCs link innate and adaptive immune systems by cross-presenting the antigens to T cells. The presence of an immunosuppressive milieu in tumors can lead to inactivation and poor functioning of NK cells and DCs, which results in an adverse outcome for many cancer patients, including those with NSCLC. Recently, clinical intervention using modified NK cells and DCs have shown encouraging response in advanced NSCLC patients. Herein, we will discuss prognostic and predictive aspects of NK cells and DC cells with an emphasis on NSCLC. Additionally, the discussion will extend to potential strategies that seek to enhance the anti-tumor functionality of NK cells and DCs.

Abstract
Hyppocrates constructed the medicines-surgery-energy triangle which includes all therapeutical modalities. Hyperthermic intraoperative chemotherapy (HITHOC) is a synergy-based single stage multimodality treatment encompassing the locoregional manifestation of the systemic malignant process. Pleural space, thermal effect, lavage/irrigation and chemotherapy represent the basic science ports of the network hub: HITHOC. The malignant transformation and process of the pleural surface (and underlying lung) challenges space management and tissue control. Thermotherapy without local chemotherapy is insufficient, similar to the normothermic local irrigation aligned with anticancer agents. The local administration of combined heat-transfer fluid and chemotherapy with or without subsequent surgical removal offers reasonable outcome in extensive primary pleural neoplasms (malignant mesothelioma), advanced (> Stage IIIA) NSCLC, functionally inoperable lung cancer and pleural carcinosis from extrathoracic malignancies. Measured by symptom-free survival and the quality of life, HITHOC in its present form, offers a modest yet fully substantiated solution. HITHOC in combination with the local application of targeted therapy and/or immunotherapy administered in the pleural space are currently under investigation. Additional development including new acting substances, their solvents and the means regarding surgical delivery and anesthesiology techniques are sign posts up ahead. Level 2 evidence are required in order to stepping up the recommendation levels, rewriting protocols and guidelines, in which HITHOC earns its revered position in the decision making process it deserves.

Abstract
BACKGROUND Lung cancer is a leading fatal malignancy due to the high incidence of treatment failure. Dysfunction of the tumor suppressor p53 contributes to cancer initiation, progression, and therapeutic resistance. Targeting MDM2, a negative regulator of p53, has recently attracted interest in cancer drug research as it may restore tumor suppressive function. PURPOSE The present study aimed to investigate the effect of 3,4-dihydroxy-5,4'-dimethoxybibenzyl (DS-1) on targeting MDM2 and restoring p53 function in lung cancer cells. METHODS The efficacy of DS-1 alone or in combination with cisplatin in lung cancer cells was determined by MTT, nuclear staining, and annexin V/PI assay. The expression of apoptosis-related proteins was determined by western blot analysis. To evaluate the role of DS-1 on the stabilization and degradation of p53, cycloheximide chasing assay and immunoprecipitation were conducted, and the active form of p53 was investigated by immunofluorescent staining assay. To confirm and demonstrate the site interaction between DS-1 and the MDM2 protein, in silico computational analysis was performed. RESULTS DS-1 exhibited a cytotoxic effect and sensitized lung cancer cells to cisplatin-induced apoptosis. DS-1 caused a significant increase in the cellular level of p53 protein, while the active form of p53 (phosphorylation at Ser15) was unaltered. DS-1 treatment in combination with cisplatin could enhance activated p-p53 (Ser15) and p53 downstream signaling (Bax, Bcl-2, and Akt), leading to a higher level of apoptosis. Immunoprecipitation analysis revealed that DS-1 decreased the p53-ubiquitin complex, a prerequisite step in p53 proteasomal degradation. Molecular docking simulation further evidenced that DS-1 interacts with MDM2 within the p53-binding domain by carbon-hydrogen bond interaction at Lys27, π-alkyl interactions at Ile37 and Leu30, and van der Waals interactions at Ile75, Val51, Val69, Phe67, Met38, Tyr43, Gly34, and Phe31. Treatment by DS-1 and cisplatin in patient-derivated primary lung cancer cells showed consistent effects by increasing cisplatin sensitivity. CONCLUSIONS Our findings provide evidence that DS-1 is an MDM2 inhibitor and its underlying mechanism involves MDM2 binding and p53 induction, which may benefit the development of this compound for lung cancer treatment.

Abstract
PURPOSE Paclitaxel-platinum chemotherapy is the first-line treatment for advanced non-small cell lung cancer (NSCLC) patients. This study quantitatively evaluated the factors influencing the efficacy and safety of the paclitaxel-platinum regimen to provide the necessary reference for the development of clinical practice and clinical trials. METHODS A literature search was performed using public databases. The parametric survival function was used to analyze the overall survival (OS) time course of patients treated with the paclitaxel-platinum regimen. The random effects model in the single-arm meta-analysis was used to analyze the objective response rate (ORR) and the incidence of grade 3-4 adverse events (AEs) under the predefined subgroups according to race and the regimen. RESULTS A total of 31 studies consisting of 3365 participants were included in the analysis. Race was the most important determinant of efficacy and safety in the paclitaxel-platinum regimen, with the median survival time and ORR in East Asians and non-East Asians being 12.2 months (95% CI: 10.5-14.4 months) and 37% (95% CI: 32-41%) and 8.4 months (95% CI: 6.5-11.0 months) and 28% (95% CI: 25-32%), respectively. The incidence of grade 3-4 AEs such as leukopenia and neutropenia was about three times higher in East Asians compared to non-East Asians. CONCLUSIONS The efficacy and safety of the paclitaxel-platinum regimen can vary between East Asian and non-East Asian populations and between different treatment schedules. The results of this study can provide a reliable and precise external control for the future evaluation of new treatment options for advanced NSCLC.

Abstract
Around 77 new oncology drugs were approved by the FDA in the past five years; however, most cancers remain untreated. Small molecules and antibodies are dominant therapeutic modalities in oncology. Antibody-drug conjugates, bispecific antibodies, peptides, cell, and gene-therapies are emerging to address the unmet patient need. Advancement in the discovery and development platforms, identification of novel targets, and emergence of new technologies have greatly expanded the treatment options for patients. Here, we provide an overview of various therapeutic modalities and the current treatment options in oncology, and an in-depth discussion of the therapeutics in the preclinical stage for the treatment of breast cancer, lung cancer, and multiple myeloma.

Abstract
Human copper transporter 1 (hCtr1) is the main transporter of copper which has been involved as an essential cofactor in biological processes and mechanisms of action for cisplatin and its analogues. Although expression of hCtr1 is present in all tissues that require copper, several studies have showed that levels of expression are highly variable between normal and neoplastic tissues. We evaluated the potential diagnostic of the 64CuCl2-PET/CT in patients with wild type non-small cell lung cancer (NSCLC). Eleven patients were included. Baseline 18F-FDG-PET/CT and 64CuCl2-PET/CT performed before to initiate treatment with platinum-based chemotherapy. 18F-FDG-PET/CT detected a total of 68 lesions in different corporal sites: lung (24), regional lymph node (30), distant non-bone metastases (17) and bone metastases (14). Of total, 73% demonstrated high focal uptake of 64CuCl2-PET/CT: 36% in primary tumor and 27% in lymph-nodes metastases. The detection-rates (DRs) was lower with 64CuCl2 PET/CT compared to 18F-FDG-PET/CT, however, these was not statistically significant (P = 0.108). A complete match was found in 2 patients. All patients were treated with platinum-based chemotherapy. According to RECIST 1.1 and PERCIST 1.0 criteria, most patients with highest uptake 64CuCl2-PET/CT presented partial response (mean 3 cycles) corroborated with 18F-FDG PET/CT. On the other hand, patients with very low uptake or faint uptake have progressive disease (3/16 patients). To our knowledge, this is the first study with 64CuCl2-PET/CT in-human in patients with NSCLC chemo-naïve. Our results may represent that 64CuCl2-PET/CT had a good ability for detect lesions. In addition, the 64CuCl2 uptake is based on the expression of Ctr1 transporters seeking to differentiate between those patients who may benefit from platinum-based therapy. More studies are necessary for confirm these findings.

Abstract
Platinum-taxane combination chemotherapy still represents the standard of care for advanced non-small cell lung cancer (NSCLC) with no targetable driver mutations. However, the efficacy of these drugs has plateaued at 10–14 months primarily due to dose-limiting toxicity, chemoresistance, and metastasis. Here, we explored the effects of withaferin A (WFA) alone and in combination with paclitaxel (PAC) on the growth, proliferation, migration, and invasion of human NSCLC cells. We show that the sensitivity of H1299 and A549 cells to concomitant treatment with PAC and WFA was greater than that of either PAC or WFA alone. Using the combination index and dose-reduction index, we demonstrated that various combinations (1:40, 1:20, 1:10) of PAC to WFA, respectively, were highly synergistic. In addition, PAC+WFA co-treatment synergistically inhibited colony formation, migration, invasion and increased the induction of apoptosis in H1299 and A549 cells. Interestingly, the synergism of PAC and WFA was not schedule-dependent but was enhanced when cells were pretreated with WFA indicating a chemo-sensitizing effect. Importantly, WFA was active against both PAC-sensitive (TS-A549) and PAC-resistant (TR-A549) cells both in vitro and in vivo. Mechanistically, WFA inhibits the proliferation of NSCLC cells via thiol oxidation. The effects of WFA were inhibited in the presence of N-acetyl cysteine and other thiol donors. Taken together, our results demonstrate the efficacy of WFA alone or alongside PAC on NSCLC cells and provide a strong rationale for further detailed testing in clinically relevant models for the development of PAC+WFA combination as an alternative therapeutic strategy for advanced NSCLC.

Abstract
α-Mangostin (MAN) is a bioactive compound isolated from the inedible pericarp of a tropical fruit mangosteen (Garcinia mangostana Linn). It exhibits notable therapeutic potentials on lung cancers, but the underlying mechanisms are still largely unknown. This study was designed to further explore the mechanisms involved in cytotoxicity of MAN on A549 cells. Apoptosis and cell cycle distribution were analyzed by flow cytometry methods. The fluorescent probes DCFH-DA and JC-1 were used to assess the intracellular reactive oxidative species (ROS) and mitochondrial membrane potential statuses, respectively. The regulation of MAN on relevant pathways was investigated by immunoblotting assays. The results obtained indicated that MAN caused significant apoptosis and cell cycle arrest in A549 cells, which eventually resulted in inhibition on cell proliferation in vitro. All these phenomena were synchronized with escalated oxidative stress and downregulation of nicotinamide phosphoribosyltransferase/nicotinamide adenine dinucleotide (NAMPT/NAD). Supplementation with nicotinamide mononucleotide (NMN) and N-acetylcysteine (NAC) efficiently eased MAN-induced ROS accumulation, and potently antagonized MAN-elicited apoptosis and cell cycle arrest. The pro-apoptotic effect of MAN was further confirmed by increased expressions of cleaved caspase 3, 6, 7, and 9, and its effect on cell cycle progression was validated by the altered expressions of p-p38, p-p53, CDK4, and cyclin D1. The immunoblotting assays also demonstrated that NAC/NMN effectively restored these molecular changes elicited by MAN treatment. Collectively, this study revealed a unique anti-tumor mechanism of MAN by provoking ROS production through downregulation of NAMPT/NAD signaling and further validated MAN as a potential therapeutic reagent for lung cancer treatment.

Epidermal growth factor receptor tyrosine kinase inhibitors combined with thoracic radiotherapy or chemoradiotherapy for advanced or metastatic non-small cell lung cancer: A systematic review and meta-analysis of single-arm trials. Medicine (Baltimore) 2019; 98:e16427. [PMID: 31335695 PMCID: PMC6708798 DOI: 10.1097/md.0000000000016427] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 05/24/2019] [Accepted: 06/17/2019] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Preclinical in vitro experiments demonstrated that epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) might have synergistic effect in combination with radiotherapy on Non-small cell lung cancer (NSCLC), but the clinical trials showed inconsistence results in NSCLC patients with EGFR status unknow or mutations. This study aimed to determine if added TKIs to Thoracic radiotherapy (TRT) improve primary disease response rate (RR) and survival outcomes in advanced or metastatic NSCLC. METHODS We searched MEDLINE, EMBASE, and Cochrane Library from January 2000 to December 2017 for eligible studies where patients received concurrent EGFR TKIs and TRT or CRT. Concerned outcomes were primary tumor RR, overall survival (OS), and adverse events (AEs). The meta-analysis was performed using Stata software (version 12.0). Random effects models were used to pool outcomes across studies. Sensitivity analysis was performed to determine if the results would be different. RESULTS We found 16 prospective clinical trials with mature results for meta-analyses. Twelve studies including 446 patients reported the RR and survival outcomes of TRT combined TKIs. The CR, PR, SD, and PD, respectively, were 0.06 (95% CI 0.03-0.09, I = 0%), 0.44 (95% CI 0.38-0.49, I = 64.9%), 0.29 (95% CI 0.24-0.34, I = 78.4%), and 0.15 (95% CI 0.11-0.19, I = 84.2%). One- and 2-year OS, respectively, were 0.52 (95% CI 0.44-0.60, I = 38.8%) and 0.26 (95% CI 0.18-0.33, I = 0%). Four studies including 182 patients reported the RR and survival outcomes of CRT combined TKIs. The pooled CR, PR, SD, and PD, respectively, were 0.12 (95% CI 0.02-0.22, I = 69.1%), 0.41 (95% CI 0.27-0.55, I71.6%), 0.31 (95% CI 0.16-0.46, I = 79%), and 0.14 (95% CI -0.01-0.30, I = 87.8%). Only 1 study reported the survival event rate, 1- and 2-year OS, respectively, were 0.83 (95% CI 0.71-0.94) and 0.67 (95% CI 0.54-0.81). There were not severe adverse events (SAEs) reported either TRT combined TKIs or CRT combined TKIs. CONCLUSION There is evidence, albeit of low quality, that added the TKIs to TRT or CRT may improve RR and survival outcomes in patients with EGFR mutant status unknown advanced or metastatic NSCLC relative to other studies of TKIs alone, TRT alone or CRT.
