Abstract
In vitro evolution and whole genome analysis has proven to be a powerful method for studying the mechanism of action of small molecules in many haploid microbes but has generally not been applied to human cell lines in part because their diploid state complicates the identification of variants that confer drug resistance. To determine if haploid human cells could be used in MOA studies, we evolved resistance to five different anticancer drugs (doxorubicin, gemcitabine, etoposide, topotecan, and paclitaxel) using a near-haploid cell line (HAP1) and then analyzed the genomes of the drug resistant clones, developing a bioinformatic pipeline that involved filtering for high frequency alleles predicted to change protein sequence, or alleles which appeared in the same gene for multiple independent selections with the same compound. Applying the filter to sequences from 28 drug resistant clones identified a set of 21 genes which was strongly enriched for known resistance genes or known drug targets (TOP1, TOP2A, DCK, WDR33, SLCO3A1). In addition, some lines carried structural variants that encompassed additional known resistance genes (ABCB1, WWOX and RRM1). Gene expression knockdown and knockout experiments of 10 validation targets showed a high degree of specificity and accuracy in our calls and demonstrates that the same drug resistance mechanisms found in diverse clinical samples can be evolved, discovered and studied in an isogenic background.

Combination drug screen targeting glioblastoma core vulnerabilities reveals pharmacological synergisms. EBioMedicine 2023; 95:104752. [PMID: 37572644 PMCID: PMC10433015 DOI: 10.1016/j.ebiom.2023.104752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 07/26/2023] [Accepted: 07/27/2023] [Indexed: 08/14/2023] Open
Abstract
BACKGROUND Pharmacological synergisms are an attractive anticancer strategy. However, with more than 5000 approved-drugs and compounds in clinical development, identifying synergistic treatments represents a major challenge. METHODS High-throughput screening was combined with target deconvolution and functional genomics to reveal targetable vulnerabilities in glioblastoma. The role of the top gene hit was investigated by RNA interference, transcriptomics and immunohistochemistry in glioblastoma patient samples. Drug combination screen using a custom-made library of 88 compounds in association with six inhibitors of the identified glioblastoma vulnerabilities was performed to unveil pharmacological synergisms. Glioblastoma 3D spheroid, organotypic ex vivo and syngeneic orthotopic mouse models were used to validate synergistic treatments. FINDINGS Nine targetable vulnerabilities were identified in glioblastoma and the top gene hit RRM1 was validated as an independent prognostic factor. The associations of CHK1/MEK and AURKA/BET inhibitors were identified as the most potent amongst 528 tested pairwise drug combinations and their efficacy was validated in 3D spheroid models. The high synergism of AURKA/BET dual inhibition was confirmed in ex vivo and in vivo glioblastoma models, without detectable toxicity. INTERPRETATION Our work provides strong pre-clinical evidence of the efficacy of AURKA/BET inhibitor combination in glioblastoma and opens new therapeutic avenues for this unmet medical need. Besides, we established the proof-of-concept of a stepwise approach aiming at exploiting drug poly-pharmacology to unveil druggable cancer vulnerabilities and to fast-track the identification of synergistic combinations against refractory cancers. FUNDING This study was funded by institutional grants and charities.

Prognostic and Immunological Potential of Ribonucleotide Reductase Subunits in Liver Cancer. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2023; 2023:3878796. [PMID: 36713030 PMCID: PMC9883104 DOI: 10.1155/2023/3878796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 11/08/2022] [Accepted: 11/30/2022] [Indexed: 01/21/2023]
Abstract
Background Ribonucleotide reductase (RR) consists of two subunits, the large subunit RRM1 and the small subunit (RRM2 or RRM2B), which is essential for DNA replication. Dysregulations of RR were implicated in multiple types of cancer. However, the abnormal expressions and biologic functions of RR subunits in liver cancer remain to be elucidated. Methods TCGA, HCCDB, CCLE, HPA, cBioPortal, and GeneMANIA were utilized to perform bioinformatics analysis of RR subunits in the liver cancer. GO, KEGG, and GSEA were used for enrichment analysis. Results The expressions of RRM1, RRM2, and RRM2B were remarkably upregulated among liver cancer tissue both in mRNA and protein levels. High expression of RRM1 and RRM2 was notably associated with high tumor grade, high stage, short overall survival, and disease-specific survival. Enrichment analyses indicated that RRM1 and RRM2 were related to DNA replication, cell cycle, regulation of nuclear division, DNA repair, and DNA recombination. Correlation analysis indicated that RRM1 and RRM2 were significantly associated with several subsets of immune cell, including Th2 cells, cytotoxic cells, and neutrophils. RRM2B expression was positively associated with immune score and stromal score. Chemosensitivity analysis revealed that sensitivity of nelarabine was positively associated with high expressions of RRM1 and RRM2. The sensitivity of rapamycin was positively associated with high expressions of RRM2B. Conclusion Our findings demonstrated high expression profiles of RR subunits in liver cancer, which may provide novel insights for predicting the poor prognosis and increased chemosensitivity of liver cancer in clinic.

Abstract
Non-muscle invasive bladder cancer (NMIBC) still represents a challenge in decision-making and clinical management since prognostic and predictive biomarkers of response to treatment are still under investigation. In addition to the risk factors defined by EORTC guidelines, histological features have also been considered key variables able to impact on recurrence and progression in bladder cancer. Conversely, the role of genomic rearrangements or expression of specific proteins at tissue level need further assessment in NMIBC. As with muscle-invasive cancer, NMIBC is a heterogeneous disease, characterized by genomic instability, varying rates of mutation and a wide range of protein tissue expression. In this Review, we summarized the recent evidence on prognostic and predictive tissue biomarkers in NMIBC, beyond morphological parameters, outlining how they could affect tumor biology and consequently its behavior during clinical care. Our aim was to facilitate clinical evaluation of promising biomarkers that may be employed to better stratify patients. We described the most common molecular events and immunohistochemical protein expressions linked to recurrence and progression. Moreover, we discussed the link between available treatments and molecular drivers that could be predictive of clinical response. In conclusion, we foster further investigations with particular focus on immunohistochemical evaluation of tissue biomarkers, a promising and cost-effective tool for daily practice.

Abstract
Purpose This study aimed to detect the expression levels of topoisomerase IIα (TOP2A), ribonucleotide reductase catalytic subunit M1 (RRM1),c-erbB-2 (HER2) and excision repair cross complementing group 1 (ERCC1) in non-muscular invasive bladder cancer (NMIBC) and explore the correlation between the expression of these genes and NMBIC sensitivity to pirarubicin or gemcitabine treatment. Materials and methods NMIBC patient tissues and the bladder cancer cell lines BIU-87 and KK47 were selected for the exploration of drug sensitivity in vitro. Immunohistochemistry was used to examine protein expression in tissues. Reverse transcription-polymerase chain reaction (RT-qPCR) and a Western blot assay were used to detect the mRNA and protein levels in cells. The cell IC50 value was evaluated by an MTT assay. Flow cytometry was used to sort the cell subpopulations. Results In the pirarubicin-treated group, the patients with high TOP2A expression experienced lower recurrence rates than those with low TOP2A expression, whereas TOP2A and HER2 co-expression resulted in higher recurrence rates. The patients with low RRM1 expression, especially those with low ERCC1 expression, experienced lower recurrence rates than the patients with high RRM1 expression in the gemcitabine-treated group. Tumour cells with high TOP2A expression were highly sensitive to pirarubicin, and TOP2A+ HER2- cells were more sensitive to pirarubicin than TOP2A+ HER2+ cells. Cells with low RRM1 expression levels were sensitive to gemcitabine, and RRM1−ERCC1- cells were more sensitive to gemcitabine than RRM1−ERCC1+ cells. Conclusion High TOP2A expression or low RRM1 expression could predict the sensitivity of NMIBC to pirarubicin or gemcitabine treatment. HER2 and ERCC1 expression may affect the effect of TOP2A and RRM1, thus affecting the efficacy of chemotherapeutic drugs.

Abstract
OBJECTIVES Abnormal expression of metabolic rate-limiting enzymes drives the occurrence and progression of hepatocellular carcinoma (HCC). This study aimed to elucidate the comprehensive model of metabolic rate-limiting enzymes associated with the prognosis of HCC. MATERIALS AND METHODS HCC animal model and TCGA project were used to screen out differentially expressed metabolic rate-limiting enzyme. Cox regression, least absolute shrinkage and selection operation (LASSO) and experimentally verification were performed to identify metabolic rate-limiting enzyme signature. The area under the receiver operating characteristic curve (AUC) and prognostic nomogram were used to assess the efficacy of the signature in the three HCC cohorts (TCGA training cohort, internal cohort and an independent validation cohort). RESULTS A classifier based on three rate-limiting enzymes (RRM1, UCK2 and G6PD) was conducted and serves as independent prognostic factor. This effect was further confirmed in an independent cohort, which indicated that the AUC at year 5 was 0.715 (95% CI: 0.653-0.777) for clinical risk score, whereas it was significantly increased to 0.852 (95% CI: 0.798-0.906) when combination of the clinical with signature risk score. Moreover, a comprehensive nomogram including the signature and clinicopathological aspects resulted in significantly predict the individual outcomes. CONCLUSIONS Our results highlighted the prognostic value of rate-limiting enzymes in HCC, which may be useful for accurate risk assessment in guiding clinical management and treatment decisions.

Abstract
BACKGROUND Susceptibility to Chronic Myeloid Leukemia (CML) may be modulated by genetic variables. However, the majority of previous investigations have focused on genetically homogeneous populations, resulting in a lack of evidence on how genetic factors may influence the development of CML in miscegenated populations. We analyzed 30 polymorphisms in genes related to DNA repair, folate metabolism, transmembrane transport, xenobiotic metabolism, and pyrimidine synthesis in relation to their potential role in the susceptibility of the individual to CML. METHODS This case-control study included 126 healthy individuals and 143 patients diagnosed with CML from the admixed population of the Brazilian Amazon. The samples were genotyped by real-time PCR and the genetic ancestry analysis was based on a panel of 61 ancestry informative markers. RESULTS The results indicated a protective effect against the development of CML in carriers of the C allele of the rs28399433 (CYP2A6) gene and the CC genotype of the rs3742106 (ABCC4) gene. CONCLUSION Our findings suggest that the rs3742106 (ABCC4) and rs28399433 (CYP2A6) polymorphisms may modulate susceptibility to CML in a population of the Brazilian Amazon region.

Midterm follow-up (3 years) confirms and extends short-term results of intravesical gemcitabine as bladder-preserving treatment for non-muscle-invasive bladder cancer after BCG failure. Urol Oncol 2020; 39:195.e7-195.e13. [PMID: 33268275 DOI: 10.1016/j.urolonc.2020.09.017] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 08/23/2020] [Accepted: 09/19/2020] [Indexed: 01/10/2023]
Abstract
BACKGROUND There is a high demand for bladder sparing therapies in patients who do not respond to bacillus Calmette-Guérin (BCG). OBJECTIVE To report the mid-term results of intravesical gemcitabine in non-muscle-invasive bladder cancer (NMIBC) patients, who failed BCG and who were unwilling to undergo radical cystectomy (RC). MATERIAL & METHODS This is an extended confirmatory open-label, single-arm study, which enrolled consecutive patients who failed BCG or were BCG intolerant and unwilling to undergo the RC (histologically confirmed Tis (CIS), T1 high grade or multifocal Ta high grade of the urinary bladder). Intravesical gemcitabine was administered once a week for 6 consecutive weeks and once a month for 12 months. The primary outcome was disease-free survival (DFS) defined as the lack of tumor on cystoscopy and negative urine cytology. The secondary endpoint was safety, defined according a grading of side effects. overall survival, progression-free survival and DFS were described with Kaplan-Meier method at 12, 24, and 36 months. RESULTS AND LIMITATIONS Overall 46 patients were enrolled. The mean follow-up was 40 months. The DFS was 69.05% at the end of induction phase and 32.69% at 36 months. The progression-free survival at 36 months was 65.38%. The overall survival and cancer specific survival were 66.97% (95% confidence interval 47.25%-80.70%) and 78.71% (95% confidence interval 59.16%-89.66%), respectively. There was no life-threatening event or treatment related death (grade 4 or 5). The most common mild and moderate adverse events reported were urinary symptoms (lower urinary tract symptoms) and fatigue (G1-G2). CONCLUSION Intravesical gemcitabine seemed to represent a valid and safe alternative at 3 years follow-up for patients who failed BCG and were unwilling to undergo RC.

Jacob F, Marchetti RL, Kind AB, Russell K, Schoetzau A, Heinzelmann-Schwarz VA. High-grade serous peritoneal cancer follows a high stromal response signature and shows worse outcome than ovarian cancer. Mol Oncol 2020; 15:91-103. [PMID: 33016563 PMCID: PMC7782088 DOI: 10.1002/1878-0261.12811] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 09/02/2020] [Accepted: 09/29/2020] [Indexed: 11/17/2022] Open
Abstract
In the era of personalized medicine, where transition from organ‐based to individualized genetic diagnosis takes place, the tailoring of treatment in cancer becomes increasingly important. This is particularly true for high‐grade, advanced FIGO stage serous adenocarcinomas of the ovary (OC), fallopian tube (TC), and peritoneum (PC), which are currently all treated identically. We analyzed three independent patient cohorts using histopathologically classified diagnosis and various molecular approaches (transcriptomics, immunohistochemistry, next‐generation sequencing, fluorescent and chromogenic in situ hybridization). Using multivariate Cox regression model, we found that PC is more aggressive compared with advanced‐stage OC independent of residual disease as shown by an earlier relapse‐free survival in two large cohorts (HR: 2.63, CI: 1.59–4.37, P < 0.001, and HR: 1.66, CI: 1.04–2.63, P < 0.033). In line with these findings, transcriptomic data revealed differentially expressed gene signatures identifying PC as high stromal response tumors. The third independent cohort (n = 4054) showed a distinction between these cancer types for markers suggested to be predictive for chemotherapy drug response. Our findings add additional evidence that ovarian and peritoneal cancers are epidemiologically and molecularly distinct diseases. Moreover, our data also suggest consideration of the tumor‐sampling site for future diagnosis and treatment decisions.

Intravesical gemcitabine as bladder‐preserving treatment for BCG unresponsive non‐muscle‐invasive bladder cancer. Results from a single‐arm, open‐label study. BJUI COMPASS 2020; 1:126-132. [PMID: 35474942 PMCID: PMC8988784 DOI: 10.1002/bco2.28] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 05/14/2020] [Accepted: 05/14/2020] [Indexed: 12/14/2022] Open
Abstract
Background There is an unmet alternative medical therapy for BCG unresponsive patients. Objective To report efficacy of intravesical gemcitabine in NMIBC patients, who failed a previous course of BCG, or intolerant, and unwilling to undergo radical cystectomy (RC). Material and methods This is an open‐label, single‐arm study, which enrolled patients showing a failure or were intolerant to BCG and unwilling to undergo the RC. Intravesical gemcitabine was administered once a week for six consecutive weeks and once a month for 12 months. The primary outcome was DFS defined as the lack of a tumor on cystoscopy and negative urine cytology. Secondary endpoint was safety defined according a grading of side effects. OS, PFS, and DFS were described with Kaplan–Meier method at 12 and 24 months. Results and limitations Overall 36 patients were enrolled. The median follow‐up was 27 months. The DFS was 68.75% at the end of induction phase and 44.44% and 31.66% at 12 and 24 months of, respectively. The PFS was 43.75%. The OS and CSS were 77.9% (95% CI 58.78%‐88.92%) and 80.68% (95% CI 61.49%‐90.96%), respectively. There was no life threatening event or treatment‐related death (grade 4 or 5). The most common mild and moderate adverse events reported were urinary symptoms (LUTS) and fatigue (G1‐G2). Conclusion Patients who presented an unresponsive‐BCG recurrent NMIBC and unwilling to receive a RC, could benefit from intravesical gemcitabine as salvage organ‐sparing treatment.
