Li H, Ma H, Ma J, Qin F, Fan S, Kong S, Zhao S, Ma J. Unveiling the role of RAC3 in the growth and invasion of cisplatin-resistant bladder cancer cells. J Cell Mol Med 2024; 28:e18473. [PMID: 38847477 PMCID: PMC11157678 DOI: 10.1111/jcmm.18473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 05/19/2024] [Accepted: 05/22/2024] [Indexed: 06/10/2024] Open
Abstract
Bladder cancer is one of the most prevalent cancers worldwide, and its morbidity and mortality rates have been increasing over the years. However, how RAC family small GTPase 3 (RAC3) affects the proliferation, migration and invasion of cisplatin-resistant bladder cancer cells remains unclear. Bioinformatics techniques were used to investigate the expression of RAC3 in bladder cancer tissues. Influences of RAC3 in the grade, stage, distant metastasis, and survival rate of bladder cancer were also examined. Analysis of the relationship between RAC3 expression and the immune microenvironment (TIME), genomic mutations, and stemness index. In normal bladder cancer cells (T24, 5637, and BIU-87) and cisplatin-resistant bladder cancer cells (BIU-87-DDP), the expression of RAC3 was detected separately with Western blotting. Plasmid transfection was used to overexpress or silence the expression of RAC3 in bladder cancer cells resistant to cisplatin (BIU-87-DDP). By adding activators and inhibitors, the activities of the JNK/MAPK signalling pathway were altered. Cell viability, invasion, and its level of apoptosis were measured in vitro using CCK-8, transwell, and flow cytometry. The bioinformatics analyses found RAC3 levels were elevated in bladder cancer tissues and were associated with a poor prognosis in bladder cancer. RAC3 in BIU-87-DDP cells expressed a higher level than normal bladder cancer cells. RAC3 overexpression promoted BIU-87-DDP proliferation. The growth of BIU-87-DDP cells slowed after the knockdown of RAC3, and RAC3 may have had an impact on the activation of the JNK/MAPK pathway.

Abstract
Recent progress in adjuvant immunotherapy offers hope for improving disease-free survival in high-risk bladder cancer (BC) and renal cell carcinoma (RCC). This review focuses on key trials such as CheckMate 274 and KEYNOTE-564, which show promising results with nivolumab in BC and pembrolizumab in RCC, including a 30% reduction in progression risk. Pembrolizumab also demonstrated overall survival (OS) benefit in RCC. The review also explores the potential of circulating tumor DNA (ctDNA) as a biomarker for better therapy selection and patient stratification. It emphasizes the need for ongoing research to establish survival benefits and suggests integrating biomarkers and risk stratification to optimize adjuvant immunotherapy in BC and RCC.

Investig Clin Urol 2024; 65:256-262. [PMID: 38714516 PMCID: PMC11076801 DOI: 10.4111/icu.20230389] [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: 11/20/2023] [Revised: 01/17/2024] [Accepted: 01/23/2024] [Indexed: 05/10/2024] Open
Abstract
PURPOSE We evaluated the risk factors associated with failure to complete gemcitabine-cisplatin (GP) neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS In total, 231 patients with MIBC treated with NAC before undergoing radical cystectomy between 2013 and 2022 participated in this study. Logistic regression analysis was performed to assess the relationship between the likelihood of incomplete NAC and clinical and demographic variables, including age, sex, hypertension (HTN), diabetes mellitus (DM), prechemotherapy glomerular filtration rate, clinical T stage, clinical N stage, and body mass index (BMI). RESULTS Of 231 patients, 209 (90.5%) and 22 (9.5%) completed and discontinued the NAC course, respectively. The mean age was 66.13±9.15, 65.63±9.07, and 70.86±8.66 years for the total sample, continuation, and discontinuation groups, respectively (p=0.010). No significant inter-group differences in sex, HTN, height, weight, BMI, pre-chemotherapy glomerular filtration rate, clinical T stage, or clinical N stage were observed. According to the results of the multivariable analysis, age (odds ratio [OR] 1.076, 95% confidence interval [CI] 1.013-1.143, p=0.018) and the presence of DM (OR 2.541, 95% CI 1.028-6.281, p=0.043) were significantly associated with NAC discontinuation. CONCLUSIONS Thus, older age and presence of DM are potential risk factors for GP NAC discontinuation in patients with MIBC. Further studies are required to validate our findings and develop strategies to minimize the rate of GP NAC discontinuation in this population.

Abstract
PURPOSE The current standard of care for muscle invasive bladder cancer (MIBC) is neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC). Previous research has shown under-utilization of NAC for treatment of MIBC, especially among the elderly. Our aim was to stratify NAC use by decade of life and analyze trends in use over time along with recording pathologic downstaging and perioperative outcomes. MATERIALS AND METHODS The National Cancer Database was queried for patients with cT2-4NanyM0 MIBC treated with RC from 2010 to 2016 with urothelial carcinoma. Nineteen thousand nine hundred fifty seven patients met criteria for analysis. We retrospectively analyzed trends in use of NAC, readmission rate, mortality rate, and pathologic downstaging with NAC all stratified by decade of life. RESULTS Of the 19,957 patients treated with RC for MIBC, only 30.9% underwent NAC. There was a statistically significant increase in NAC use across all age groups from 2010 to 2016. Receipt of NAC was associated with decreased age on univariate analysis (P < 0.001) and on logistic regression (OR: 0.617 for age 70-79, OR: 0.221 for age ≥80 vs. age <60; P < 0.001). Patients receiving NAC were more likely to exhibit pathologic downstaging at time of RC (OR: 3.907; P < 0.001), and this trend held for each age group examined. Among patients receiving NAC, the risk of 30 and 90-day mortality was associated with increasing age; however, age was not associated with 30-day readmission for those receiving NAC. CONCLUSION Rates of NAC use prior to RC have increased among all age groups with the lowest utilization rate among the elderly. NAC use was associated with greater pathologic downstaging in all age groups. These data show a promising trend in the uptake of the gold standard for treatment of MIBC; however, the underlying etiology of differing rates of NAC utilization remains to be determined.

Abstract
The pursuit of surgeons and oncologists in fulfilling the inherent desire of patients to retain their urinary bladder despite having muscle-invasive bladder cancer (MIBC) has sparked years of research and multiple debates, given its aggressive nature and the high risk of fatal metastatic recurrence. Historically, several approaches to bladder-sparing treatment have been explored, ranging from radical transurethral resection to concurrent chemoradiation. A less well-established approach involves a risk-adapted approach with local therapy deferred based on the clinical response to transurethral resection followed by systemic therapy. Each approach is associated with potential risks, benefits, and trade-offs. In this review, we aim to understand, navigate, and suggest future perspectives on bladder-sparing approaches in patients with MIBC.

Abstract
Necroptosis, a controlled type of cell death that is different from apoptosis, has become a key figure in the aetiology of cancer and offers a possible target for treatment. A growing number of biological activities, including necroptosis, have been linked to long noncoding RNAs (lncRNAs), a varied family of RNA molecules with limited capacity to code for proteins. The complex interactions between LncRNAs and important molecular effectors of necroptosis, including mixed lineage kinase domain-like pseudokinase (MLKL) and receptor-interacting protein kinase 3 (RIPK3), will be investigated. We will explore the many methods that LncRNAs use to affect necroptosis, including protein-protein interactions, transcriptional control, and post-transcriptional modification. Additionally, the deregulation of certain LncRNAs in different forms of cancer will be discussed, highlighting their dual function in influencing necroptotic processes as tumour suppressors and oncogenes. The goal of this study is to thoroughly examine the complex role that LncRNAs play in controlling necroptotic pathways and how that regulation affects the onset and spread of cancer. In the necroptosis for cancer treatment, this review will also provide insight into the possible therapeutic uses of targeting LncRNAs. Techniques utilising LncRNA-based medicines show promise in controlling necroptotic pathways to prevent cancer from spreading and improve the effectiveness of treatment.

Abstract
Patients with bladder cancer (BCa) frequently acquires resistance to platinum-based chemotherapy, particularly cisplatin. This study centered on the mechanism of cisplatin resistance in BCa and highlighted the pivotal role of lactylation in driving this phenomenon. Utilizing single-cell RNA sequencing, we delineated the single-cell landscape of Bca, pinpointing a distinctive subset of BCa cells that exhibit marked resistance to cisplatin with association with glycolysis metabolism. Notably, we observed that H3 lysine 18 lactylation (H3K18la) plays a crucial role in activating the transcription of target genes by enriching in their promoter regions. Targeted inhibition of H3K18la effectively restored cisplatin sensitivity in these cisplatin-resistant epithelial cells. Furthermore, H3K18la-driven key transcription factors YBX1 and YY1 promote cisplatin resistance in BCa. These findings enhance our understanding of the mechanisms underlying cisplatin resistance, offering valuable insights for identifying novel intervention targets to overcome drug resistance in Bca.

Abstract
Bladder cancer remains a leading cause of cancer death worldwide and is associated with substantial impacts on patient quality of life, morbidity, mortality, and cost to the healthcare system. Gross hematuria frequently precedes the diagnosis of bladder cancer. Non-muscle-invasive bladder cancer (NMIBC) is managed initially with transurethral resection of a bladder tumor (TURBT), followed by a risk stratified approach to adjuvant intravesical therapy (IVe), and is associated with an overall survival of 90%. However, cure rates remain lower for muscle invasive bladder cancer (MIBC) owing to a variety of factors. NMIBC and MIBC groupings are heterogeneous and have unique pathological and molecular characteristics. Indeed, The Cancer Genome Atlas project identified genetic drivers and luminal and basal molecular subtypes of MIBC with distinct treatment responses. For NMIBC, IVe immunotherapy (primarily BCG) is the gold standard treatment for high grade and high risk NMIBC to reduce or prevent both recurrence and progression after initial TURBT; novel trials incorporate immune checkpoint inhibitors. IVe gene therapy and combination IVe chemotherapy have recently been completed, with promising results. For localized MIBC, essential goals are improving care and reducing morbidity following cystectomy or bladder preserving strategies. In metastatic disease, advances in understanding of the genomic landscape and tumor microenvironment have led to the implementation of immune checkpoint inhibitors, targeted treatments, and antibody-drug conjugates. Defining better selection criteria to identify the patients most likely to benefit from a specific treatment is an urgent need.

Abstract
Locally advanced or metastatic urothelial carcinoma (aUC) presents a significant challenge with high mortality rates. Platinum-based chemotherapy remains the established frontline standard of care, and a switch-maintenance strategy with immunotherapy has now emerged as a new standard for aUC patients without disease progression, following initial platinum therapy. Examining the treatment patterns is imperative, given the evolving therapeutic landscape. In this study, we conducted a retrospective medical chart review of 17 Canadian oncologists treating patients with aUC to assess unmet needs in Canadian aUC patient care. Data from 146 patient charts were analyzed, revealing important clinical insights about the management of aUC. A substantial proportion of patients (53%) presented with de novo metastatic disease, which was possibly influenced by pandemic-related care disruptions. Variability was evident in the cisplatin eligibility criteria, with a majority (70%) of oncologists utilizing a 50 mL/min threshold. Most favored four cycles of platinum-based chemotherapy to spare the bone marrow for future therapies and prevent patient fatigue. Notably, some eligible patients were kept under surveillance rather than receiving maintenance therapy, suggesting a potential gap in awareness regarding evidence-based recommendations. Furthermore, managing treatment-related adverse events was found to be one of the biggest challenges in relation to maintenance immunotherapy. In conclusion, our findings provide the first comprehensive overview of aUC treatment patterns in Canada following the approval of maintenance immunotherapy, offering insights into the decision-making process and underscoring the importance of evidence-based guidelines in aUC patient management.

PURPOSE Urothelial cancer accounts for approximately 3% of new cancer cases worldwide, with a high burden of disease in countries with medium and low human development indexes where its incidence and mortality are increasing. The purpose of this consensus is to develop statements on the evaluation and treatment of locally advanced and metastatic urothelial carcinoma that would further guide the clinical practice in Latin America. METHODS A systematic review of the literature was conducted by an independent team of methodologists. Then, a modified Delphi method was developed with clinical specialists from different Latin American countries. RESULTS Forty-two consensus statements, based on evidence, were developed to address the staging, the evaluation (suitability for chemotherapy, risk assessment, and biomarkers), and systemic treatment (first-line and subsequent therapies) of locally advanced or metastatic urothelial carcinoma. The statements made in this consensus are suggested practice recommendations in the Latin American context; however, the importance of a complete and individualized patient evaluation as a guide for therapeutic selection is highlighted. The availability and affordability of support tools for the evaluation of the disease, as well as specific therapies, may limit the application of the best practices suggested. RECOMMENDATIONS Therapeutic decisions need to be tailored to the context-specific clinical setting and availability of resources. Local research is promoted to improve outcomes for patients with this challenging cancer in Latin America.

Cancers (Basel) 2023; 16:125. [PMID: 38201552 PMCID: PMC10778480 DOI: 10.3390/cancers16010125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 12/13/2023] [Accepted: 12/23/2023] [Indexed: 01/12/2024] Open
Abstract
Autophagy-dependent cisplatin resistance poses a challenge in bladder cancer treatment. SIRT1, a protein deacetylase, is involved in autophagy regulation. However, the precise mechanism through which SIRT1 mediates cisplatin resistance in bladder cancer via autophagy remains unclear. In this study, we developed a cisplatin-resistant T24/DDP cell line to investigate this mechanism. The apoptosis rate and cell viability were assessed using flow cytometry and the CCK8 method. The expression levels of the relevant RNA and protein were determined using RT-qPCR and a Western blot analysis, respectively. Immunoprecipitation was utilized to validate the interaction between SIRT1 and Beclin1, as well as to determine the acetylation level of Beclin1. The findings indicated the successful construction of the T24/DDP cell line, which exhibited autophagy-dependent cisplatin resistance. Inhibiting autophagy significantly reduced the drug resistance index of these cells. The T24/DDP cell line showed a high SIRT1 expression level. The overexpression of SIRT1 activated autophagy, thereby further promoting cisplatin resistance in the T24/DDP cell line. Conversely, inhibiting autophagy counteracted the cisplatin-resistance-promoting effects of SIRT1. Silencing SIRT1 led to increased acetylation of Beclin1, the inhibition of autophagy, and a reduction in the cisplatin resistance of the T24/DDP cell line. Introducing a double mutation (lysine 430 and 437 to arginine, 2KR) in Beclin-1 inhibited acetylation and activated autophagy, effectively reversing the decreased cisplatin resistance resulting from SIRT1 silencing. In summary, our study elucidated that SIRT1 promotes cisplatin resistance in human bladder cancer T24 cells through Beclin1-deacetylation-mediated autophagy activation. These findings suggest a potential new strategy for reversing cisplatin resistance in bladder cancer.

Abstract
PURPOSE There is a significant unmet need for new and efficacious therapies in urothelial cancer (UC). To provide recommendations on appropriate clinical trial designs across disease settings in UC, the Society for Immunotherapy of Cancer (SITC) and the International Bladder Cancer Group (IBCG) convened a multidisciplinary, international consensus panel. METHODS Through open communication and scientific debate in small- and whole-group settings, surveying, and responses to clinical questionnaires, the consensus panel developed recommendations on optimal definitions of the disease state, end points, trial design, evaluations, sample size calculations, and pathology considerations for definitive studies in low- and intermediate-risk nonmuscle-invasive bladder cancer (NMIBC), high-risk NMIBC, muscle-invasive bladder cancer in the neoadjuvant and adjuvant settings, and metastatic UC. The expert panel also solicited input on the recommendations through presentations and public discussion during an open session at the 2021 Bladder Cancer Advocacy Network (BCAN) Think Tank (held virtually). RESULTS The consensus panel developed a set of stage-specific bladder cancer clinical trial design recommendations, which are summarized in the table that accompanies this text. CONCLUSION These recommendations developed by the SITC-IBCG Bladder Cancer Clinical Trial Design consensus panel will encourage uniformity among studies and facilitate drug development in this disease.

Effects of Lactate Transport Inhibition by AZD3965 in Muscle-Invasive Urothelial Bladder Cancer. Pharmaceutics 2023; 15:2688. [PMID: 38140029 PMCID: PMC10747642 DOI: 10.3390/pharmaceutics15122688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 07/31/2023] [Accepted: 11/24/2023] [Indexed: 12/24/2023] Open
Abstract
The Warburg Effect is characterized by high rates of glucose uptake and lactate production. Monocarboxylate transporters (MCTs) are crucial to avoid cellular acidosis by internal lactate accumulation, being largely overexpressed by cancer cells and associated with cancer aggressiveness. The MCT1-specific inhibitor AZD3965 has shown encouraging results in different cancer models. However, it has not been tested in urothelial bladder cancer (UBC), a neoplasm where rates of recurrence, progression and platinum-based resistance are generally elevated. We used two muscle-invasive UBC cell lines to study AZD3965 activity regarding lactate production, UBC cells' viability and proliferation, cell cycle profile, and migration and invasion properties. An "in vivo" assay with the chick chorioallantoic membrane model was additionally performed, as well as the combination of the compound with cisplatin. AZD3965 demonstrated anticancer activity upon low levels of MCT4, while a general lack of sensitivity was observed under MCT4 high expression. Cell viability, proliferation and migration were reduced, cell cycle was arrested, and tumor growth "in vivo" was inhibited. The compound sensitized these MCT4-low-expressing cells to cisplatin. Thus, AZD3965 seems to display anticancer properties in UBC under a low MCT4-expression setting, but additional studies are necessary to confirm AZD3965 activity in this cancer model.

Preclinical evaluation of bozepinib in bladder cancer cell lines: modulation of the NPP1 enzyme. Purinergic Signal 2023:10.1007/s11302-023-09975-6. [PMID: 37906424 DOI: 10.1007/s11302-023-09975-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 10/20/2023] [Indexed: 11/02/2023] Open
Abstract
Bladder cancer (BC) is the most common cancer of the urinary tract. Bozepinib (BZP), a purine-derived molecule, is a potential compound for the treatment of cancer. Purinergic signaling consists of the activity of nucleosides and nucleotides present in the extracellular environment, modulating a variety of biological actions. In cancer, this signaling is mainly controlled by the enzymatic cascade involving the NTPDase/E-NPP family and ecto-5'-nucleotidase/CD73, which hydrolyze extracellular adenosine triphosphate (ATP) to adenosine (ADO). The aim of this work is to evaluate the activity of BZP in the purinergic system in BC cell lines and to compare its in vitro antitumor activity with cisplatin, a chemotherapeutic drug widely used in the treatment of BC. In this study, two different BC cell lines, grade 1 RT4 and the more aggressive grade 3 T24, were used along with a human fibroblast cell line MRC-5, a cell used to predict the selectivity index (SI). BZP shows strong antitumor activity, with notable IC50 values (8.7 ± 0.9 µM for RT4; 6.7 ± 0.7 µM for T24), far from the SI for cisplatin (SI for BZP: 19.7 and 25.7 for RT4 and T24, respectively; SI for cisplatin: 1.7 for T24). BZP arrests T24 cells in the G2/M phase of the cell cycle, inducing early apoptosis. Moreover, BZP increases ATP and ADP hydrolysis and gene/protein expression of the NPP1 enzyme in the T24 cell line. In conclusion, BZP shows superior activity compared to cisplatin against BC cell lines in vitro.

Patterns of Utilization and Outcomes of Perioperative Chemotherapy in Patients With Locally Advanced-urothelial Bladder Cancer (LABC)-Real World Data From an Indian Tertiary Care Cancer Center. Clin Genitourin Cancer 2023; 21:e326-e333.

Abstract
AIM Optimal utilization of perioperative systemic therapy in locally advanced bladder cancer (LABC) holds the key in improving the survival outcomes. We aim to analyze the oncological outcomes of clinically locally advanced urothelial bladder cancer patients treated with neoadjuvant (NACT) or adjuvant chemotherapy or without any systemic therapy in the perioperative period of radical cystectomy. METHODS & MATERIAL We retrospectively analyzed the medical records of patients with cancer of the urinary bladder diagnosed between 2012 and 2020. The demographic profile, and the treatment received, was recorded for all patients. Oncological outcomes of the patients based on these variables were analyzed. RESULTS Two hundred and twenty nine (229) locally advanced bladder cancer patients were included in the study. Eighty eight (38%) of them underwent upfront radical cystectomy and 141 (62%) received neoadjuvant chemotherapy (NACT). With a median follow-up of 27 months, the 2-year DFS in either of the groups was 65.4% and 67.1% respectively (P - 0.373). In the multivariate analysis, the pathological lymph nodal status and lymph vascular invasion (LVI) status influenced the DFS. The initial modality of management chosen did not affect the outcome. (HR - 0.688; 95% CI: 0.38-1.21). The commonest reason for not receiving NACT was Cisplatin ineligibility due to malignant obstructive uropathy and a subgroup analysis of this set of patients also did not show any significant difference in 2 year DFS compared to those who received NACT. CONCLUSION A significant proportion of patients with LABC are unable to receive the recommended neoadjuvant chemotherapy and obstructive uropathy is the commonest reason for this in our centre. In our single centre series upfront radical cystectomy followed by adjuvant platinum based therapy had an outcome similar to neoadjuvant chemotherapy in LABC patients, in patients who were unable to receive the same due to various reasons.

Abstract
Key Points Many patients with metastatic urothelial carcinoma are deemed cisplatin-ineligible because of reduced kidney function. Options include split-dose cisplatin or carboplatin. There was no significant association between regimen type and AKI. Alternative regimens were associated with higher risk of progressive disease. There is a need to revisit cisplatin eligibility criteria and develop strategies to optimize cancer treatment for patients with CKD. Background Cisplatin-based chemotherapy regimens remain the optimal first-line treatment for patients with metastatic urothelial carcinoma (mUC). However, many patients are deemed cisplatin-ineligible, predominantly because of reduced kidney function. Other treatment options include split-dose cisplatin, carboplatin, and non–platinum-based regimens. We compared the incidence of AKI and cancer outcomes within three chemotherapy regimens. Methods We conducted a single-center retrospective study of patients with mUC who received first-line chemotherapy from 2005 to 2019. We compared standard gemcitabine–cisplatin (gem-cis) with two alternative regimens: (1 ) gem-cis split-dose regimen (split) with cisplatin divided over days 1 and 8 and (2 ) combination of gemcitabine–carboplatin or single-agent gemcitabine (gem/gem-carbo). The primary outcome was Kidney Disease Improving Global Outcomes–defined AKI. Secondary outcomes included overall survival and progression-free survival. Results We identified 183 patients (98 gem-cis, 32 split, and 53 gem/gem-carbo). Median baseline eGFR in the gem/cis group was 78 ml/min per 1.73 m2 (interquartile range, 66–91), in the split group 64 (48–77), and in the gem/gem-carbo 45 (33–57). There was no significant association between regimen type and incidence of AKI when adjusted for age, Eastern Cooperative Oncology Group, baseline eGFR, hypertension, diabetes, and visceral disease. The adjusted hazard ratios were 1.31 (95% confidence interval [CI], 0.61 to 2.78; P = 0.49) and 0.98 (95% CI, 0.46 to 2.07; P = 0.95) for split and gem/gem-carbo groups, respectively, versus gem-cis. Split and gem/gem-carbo regimens were associated with higher mortality and progressive disease relative to gem-cis with an adjusted hazard ratio of 1.54 (95% CI, 1.02 to 2.33; P = 0.04) and 1.96 (95% CI, 1.31 to 2.95; P < 0.01), respectively. Median progression free survival was 8.1 (interquartile range, 4.6–14.8), 6.1 (4.1–9.3), and 4.4 (2.3–8.6) months in the gem-cis, split, and gem/gem-carbo groups. Conclusions There was no significant difference in the incidence of AKI between the three regimens studied. However, standard gem-cis was associated with improved cancer outcomes. Novel regimens and kidney protective strategies are needed for patients with mUC with kidney disease.

Chen R, Hao X, Chen J, Zhang C, Fan H, Lian F, Chen X, Wang C, Xia Y. Integrated multi-omics analyses reveal Jorunnamycin A as a novel suppressor for muscle-invasive bladder cancer by targeting FASN and TOP1. J Transl Med 2023; 21:549. [PMID: 37587470 PMCID: PMC10428641 DOI: 10.1186/s12967-023-04400-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Accepted: 07/29/2023] [Indexed: 08/18/2023] Open
Abstract
BACKGROUND Bladder cancer is a urological carcinoma with high incidence, among which muscle invasive bladder cancer (MIBC) is a malignant carcinoma with high mortality. There is an urgent need to develop new drugs with low toxicity and high efficiency for MIBC because existing medication has defects, such as high toxicity, poor efficacy, and side effects. Jorunnamycin A (JorA), a natural marine compound, has been found to have a high efficiency anticancer effect, but its anticancer function and mechanism on bladder cancer have not been studied. METHODS To examine the anticancer effect of JorA on MIBC, Cell Counting Kit 8, EdU staining, and colony formation analyses were performed. Moreover, a xenograft mouse model was used to verify the anticancer effect in vivo. To investigate the pharmacological mechanism of JorA, high-throughput quantitative proteomics, transcriptomics, RT-qPCR, western blotting, immunofluorescence staining, flow cytometry, pulldown assays, and molecular docking were performed. RESULTS JorA inhibited the proliferation of MIBC cells, and the IC50 of T24 and UM-UC-3 was 0.054 and 0.084 μM, respectively. JorA-induced significantly changed proteins were enriched in "cancer-related pathways" and "EGFR-related signaling pathways", which mainly manifested by inhibiting cell proliferation and promoting cell apoptosis. Specifically, JorA dampened the DNA synthesis rate, induced phosphatidylserine eversion, and inhibited cell migration. Furthermore, it was discovered that fatty acid synthase (FASN) and topoisomerase 1 (TOP1) are the JorA interaction proteins. Using DockThor software, the 3D docking structures of JorA binding to FASN and TOP1 were obtained (the binding affinities were - 8.153 and - 7.264 kcal/mol, respectively). CONCLUSIONS The marine compound JorA was discovered to have a specific inhibitory effect on MIBC, and its potential pharmacological mechanism was revealed for the first time. This discovery makes an important contribution to the development of new high efficiency and low toxicity drugs for bladder cancer therapy.

Self-polymerized platinum (II)-Polydopamine nanomedicines for photo-chemotherapy of bladder Cancer favoring antitumor immune responses. J Nanobiotechnology 2023; 21:235.

Abstract
Systemic administration of platinum-based drugs has obvious limitations in the treatment of advanced bladder cancer (BC) owing to lower tumor accumulation and uncontrolled release of chemotherapeutics. There is an urgent need for advanced strategies to overcome the current limitations of platinum-based chemotherapy, to achieve maximal therapeutic outcomes with reduced side effects. In this study, self-polymerized platinum (II)-polydopamine nanocomplexes (PtPDs) were tailored for efficient chemo-photoimmunotherapy of BC. PtPDs with high Pt loading content (11.3%) were degradable under the combination of a reductive tumor microenvironment and near-infrared (NIR) light irradiation, thus controlling the release of Pt ions to achieve efficient chemotherapy. In addition, polydopamine promoted stronger photothermal effects to supplement platinum-based chemotherapy. Consequently, PtPDs provided effective chemo-photothermal therapy of MB49 BC in vitro and in vivo, strengthening the immunogenic cell death (ICD) effect and robust anti-tumoral immunity response. When combined with a PD-1 checkpoint blockade, PtPD-based photochemotherapy evoked systemic immune responses that completely suppressed primary and distant tumor growth without inducing systemic toxicities. Our work provides a highly versatile approach through metal-dopamine self-polymerization for the precise delivery of metal-based chemotherapeutic drugs, and may serve as a promising nanomedicine for efficient and safe platinum-based chemotherapy for BC.

Abstract
Gastric cancer (GC) is a prevalent malignancy in the digestive system that poses a serious threat to human health. Anti-silencing function 1B (ASF1B) performs an important role in the progression of numerous tumors; however, its function in GC still requires further elucidation. Using data from The Cancer Genome Atlas, the expression levels of ASF1B in GC tissues were analyzed and a survival curve for high-ASF1B expression and low-ASF1B expression groups was plotted using the Kaplan-Meier method. Reverse transcription-quantitative PCR was performed to evaluate ASF1B expression in GC tissues and cells. Small interfering RNAs targeting ASF1B were transfected into HGC-27 and AGS cells to silence ASF1B expression. Cell viability, proliferation, migration, invasion, and apoptosis in HGC-27 and AGS cells was assessed using cell counting kit-8 assay, colony formation assay, wound healing assay, Transwell assay and flow cytometry, respectively. The protein changes were assessed using western blotting. Gene Set Enrichment Analysis (GSEA) was used to identify ASF1B related pathways. The results demonstrated that ASF1B expression was increased in GC tissues and cells compared with adjacent healthy tissues and normal cells (GES-1), and high expression of ASF1B was associated with poor survival outcomes in patients with GC. Silencing ASF1B inhibited cell viability, colony formation, migration, invasion and cisplatin resistance, while also attenuating the apoptotic capability of HGC-27 and AGS cells. GSEA showed that ASF1B could activate the Myc-targets-v1 and Myc-targets-v2 pathways. Moreover, silencing ASF1B inhibited the Myc pathway-related proteins Myc, minichromosome maintenance (MCM)4 and MCM5. Overexpression of Myc reversed the inhibitory effect of ASF1B silencing on AGS cell proliferation, invasion and cisplatin resistance. In conclusion, the results indicate that knockdown of ASF1B may suppress GC cell proliferation, migration and invasion, and promote cell apoptosis and cisplatin sensitivity by modulating the Myc pathway, thereby offering novel possibilities for reversing cisplatin resistance in GC.

Abstract
Cisplatin is a highly effective chemotherapeutic agent that has been used for more than 50 years for a variety of cancers; however, its use is limited by toxicity, including nephrotoxicity. In this in-depth review, we discuss the incidence of cisplatin-associated acute kidney injury, as well as common risk factors for its development. Cisplatin accumulates in the kidney tubules and causes AKI through various mechanisms, including DNA damage, oxidative stress, and apoptosis. We also discuss the spectrum of nephrotoxicity, including acute and chronic impairment of kidney function, electrolyte disturbances, and thrombotic microangiopathy. We discuss the limited options for the diagnosis, prevention, and management of these complications, along with factors that may impact future therapy with or without cisplatin. We conclude with directions for future research in this expanding and important area.

Abstract
Bladder cancer ranks as the 10th most common cancer type globally, and muscle-invasive disease accounts for approximately 25% of newly diagnosed bladder cancers. Despite definitive treatment, 50% of patients with muscle-invasive bladder cancer (MIBC) develop metastasis within 2 years, leading to death. Perioperative systemic therapy is generally recommended to control local relapse or distant metastasis after surgical resection for patients with MIBC. Cisplatin-based neoadjuvant chemotherapy followed by radical cystectomy is the current standard treatment to improve oncologic control and survival outcomes. Adjuvant chemotherapy is recommended for patients with pathological T3-4 or positive lymph nodes after radical cystectomy if no neoadjuvant chemotherapy was given. Nonetheless, perioperative systemic therapy is not applied widely because of its toxicity, and less than 25% of patients receive cisplatin-based neoadjuvant chemotherapy. Therefore, the development of predictive biomarkers for neoadjuvant chemotherapy efficacy and alternative effective regimens for cisplatin-ineligible patients are important. Furthermore, recently, novel anticancer agents such as immune checkpoint inhibitors and antibody-drug conjugates have proven survival benefits in the metastatic setting, thereby expanding their therapeutic applications to the perioperative setting for non-metastatic MIBC. Herein, we discuss the current status and future perspectives of perioperative systemic strategies for MIBC.

Abstract
In 2020 the number of cases of newly diagnosed urothelial cancer in Germany was approximately 35,000, making urothelial cancer the fifth most common form of cancer in this country in terms of incidence. If systemic recurrence occurs the risk of dying from urothelial cancer is high. For this reason, perioperative concepts that improve the overall survival around curatively intended cystectomy are becoming increasingly more important as part of multimodal concepts for urothelial cancer. In the neoadjuvant setting, platinum-based chemotherapy currently remains the gold standard and can also be used in the adjuvant setting. Recently, immunotherapy has gained in importance for adjuvant treatment. Further innovations, such as the use of immunotherapy in the neoadjuvant setting or combination therapies in both situations can be expected. This article provides insights into the current recommendations and highlights possible new concepts.

Abstract
OPINION STATEMENT Significant advancements have been made in the treatment of locally advanced head and neck cancer, predominantly driven by the integration of concurrent chemotherapy with radiation therapy as a standard of care for many patients. The most heavily investigated chemotherapeutic is cisplatin, yet many patients are ineligible for cisplatin due to the presence of pre-existing medical comorbidities. Moreover, given the toxicity profile of cisplatin, identifying which patients stand to benefit from cisplatin is challenging, which is particularly evident in older patients. Efforts to better risk-stratify patients based on age, performance status, and the degree of pre-existing comorbidities are ongoing and have been increasingly utilized in national clinical trials. In parallel, exploration into alternative systemic agents, including novel targeted therapies and immunotherapies, in cisplatin-ineligible patients are rapidly expanding. Cumulatively, identifying appropriate treatment paradigms in patients who harbor contraindications to cisplatin can not only improve clinical outcomes but also critically mitigate detrimental adverse effects.

Abstract
Objectives To analyze the correlations between the expression and effect of DNA damage repair genes and the immune status and clinical outcomes of urothelial bladder cancer (BLCA) patients. In addition, we evaluate the efficacy and value of utilizing the DNA damage repair genes signature as a prognosis model for BLCA. Methods Two subtype groups (C1 and C2) were produced based on the varied expression of DNA damage repair genes. Significantly differentiated genes and predicted enriched gene pathways were obtained between the two subtypes. Seven key genes were obtained from the DNA damage repair-related genes and a 7-gene signature prognosis model was established based on the key genes. The efficacy and accuracy of this model in prognosis prediction was evaluated and verified in two independent databases. Also, the difference in biological functions, drug sensitivity, immune infiltration and affinity between the high-risk group and low-risk group was analyzed. Results The DNA damage repair gene signature could significantly differentiate the BLCA into two molecular subgroups with varied genetic expression and enriched gene pathways. Seven key genes were screened out from the 232 candidate genes for prognosis prediction and a 7-gene signature prognosis model was established based on them. Two independent patient cohorts (TCGA cohort and GEO cohort) were utilized to validate the efficacy of the prognosis model, which demonstrated an effective capability to differentiate and predict the overall survival of BLCA patients. Also, the high-risk group and low-risk group derived from the 7-gene model exhibited significantly differences in drug sensitivity, immune infiltration status and biological pathways enrichment. Conclusions Our established 7-gene signature model based on the DNA damage repair genes could serve as a novel prognosis predictive tool for BLCA. The differentiation of BLCA patients based on the 7-gene signature model may be of great value for the appropriate selection of specific chemotherapy agents and immune-checkpoint blockade therapy administration.

Abstract
Proliferating cancer cells are able to reprogram their energy metabolism, favouring glycolysis even in the presence of oxygen and fully functioning mitochondria. Research is needed to validate the glycolysis-related proteins as prognostic/predictive biomarkers in urothelial bladder carcinoma (UBC), a malignancy tagged by high recurrence rates and poor response to chemotherapy. Here, we assessed GLUT1, HK2, PFKL, PKM2, phospho-PDH, and LDHA immunoexpression in 76 UBC samples, differentiating among urothelial, fibroblast, and endothelial cells and among normoxic versus hypoxic areas. We additionally studied the functional effects of the HK2 inhibitor 2-deoxy-D-glucose (2DG) in "in vitro" and "in vivo" preclinical UBC models. We showed that the expression of the glycolysis-related proteins is associated with UBC aggressiveness and poor prognosis. HK2 remained as an independent prognostic factor for disease-free and overall survival. 2DG decreased the UBC cell's viability, proliferation, migration, and invasion; the inhibition of cell cycle progression and apoptosis occurrence was also verified. A significant reduction in tumour growth and blood vessel formation upon 2DG treatment was observed in the chick chorioallantoic membrane assay. 2DG potentiated the cisplatin-induced inhibition of cell viability in a cisplatin-resistant subline. This study highlights HK2 as a prognostic biomarker for UBC patients and demonstrates the potential benefits of using 2DG as a glycolysis inhibitor. Future studies should focus on integrating 2DG into chemotherapy design, as an attempt to overcome cisplatin resistance.

Abstract
Neoadjuvant chemotherapy (NAC), which aims to eliminate micrometastatic disease, has been established as the standard of care for patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC). This is based on randomized controlled trials showing a survival benefit of NAC prior to RC compared to RC alone. It was anticipated that a similar survival benefit would also be seen when NAC was given prior to bladder preserving approaches, but the e phase III RTOG 8903 study which explored this concept was reported to be a negative study. However, there are a number of important caveats to be considered. First, the profile of patients opting for bladder preservation has changed from the older, frailer non-surgical candidates, to now also include younger, fitter patients opting for bladder preservation and who are also more likely to tolerate NAC. In recent years, there have also been important advances in systemic chemotherapy, immunotherapy, radiation techniques, and supportive care. As such revisitng the role of NAC prior to bladder preserving approaches in MIBC appears warranted.

Abstract
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series was to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.The systemic treatment for metastatic urothelial carcinoma has evolved over the past decade; however, changes in the first-line setting have remained elusive and dependent on platinum-based chemotherapy regimens. Hoimes et al now present an update on the results of cohort A of the EV-103 phase Ib/II trial combining enfortumab vedotin and pembrolizumab in the first-line setting for patients with cisplatin-ineligible metastatic urothelial carcinoma. The efficacy results in this small, phase I cohort demonstrate an impressive response rate with the majority of patients deriving benefit in tumor control. In conjunction with the results from cohort K of EV-103, recently reported at the 2022 ESMO Congress, there is much anticipation regarding this combination as a future standard of care. However, despite this combination not including a traditional cytotoxic chemotherapeutic, it is still associated with potentially life-altering treatment-related toxicity, most notably rash and peripheral neuropathy, along with the risks of immune-related adverse events, which will need to be carefully calibrated for patients.

Abstract
OBJECTIVES We investigated AB0 blood groups prevalence according to preoperative and pathological tumor characteristics, and their association with oncological outcomes, and renal function decline in a contemporary large cohort of bladder cancer (BCa) patients, who underwent radical cystectomy (RC) at a tertiary referral center. MATERIALS AND METHODS We retrospectively evaluated data of patients with histologically confirmed and clinically non metastatic BCa, who underwent RC between 2014 and 2021 at our Institution. Kaplan-Meier (KM) plots and Cox regression (CR) models tested the relationship between AB0 blood groups and local recurrence-, metastasis-, cancer specific mortality-, and overall mortality-free survival. Logistic regression (LR) models tested the association between AB0 blood groups and renal function decline, defined as an estimated Glomerular Filtration Rate (eGFR) < 60 mL/min, at post-operative day 1, discharge and 6- months of follow-up. RESULTS Of 301 included patients, 128 (42.5%) had group A, 126 (41.9%) had group 0, 28 (9.3%) had group B, and 19 (6.3%) had group AB. Patients with group 0 developed higher rates of muscle- invasive BCa (p = 0.028) with high-grade features (p = 0.005) at last bladder resection, and less frequently received preoperative immunotherapy with Bacillus of Calmette-Guerin (p = 0.044), than their non-0 counterparts. Additionally, these patients harbored more advanced pathologic tumor stage at RC (p = 0.024). KM plots showed no differences among all tested cancer control outcomes between AB0 blood groups (p > 0.05 in all cases). Patients with group AB presented the lowest median eGFR at each time point. In multivariable LR analyses addressing renal function decline, group AB was independently associated with eGFR< 60 mL/min at discharge (Odds Ratio: 4.28, p = 0.047). CONCLUSIONS Among AB0 blood groups, patients with group 0 exhibited the most aggressive tumor profile. However, no differences were recorded in recurrence or survival rates. Group AB independently predicted renal function decline at discharge.

Circular RNA circ_0005667 promotes cisplatin resistance of endometrial carcinoma cells by regulating IGF2BP1 through miR-145-5p. Anticancer Drugs 2022:00001813-990000000-00156.

Abstract
BACKGROUND Circular RNA (circRNA) plays a significant role in cisplatin (DDP) resistance. The purpose of this study was to explore the role of circ_0005667 in DDP resistance of endometrial carcinoma (EC) cells. METHODS The expression of circular RNA circ_0005667, microRNA-145-5p (miR-145-5p) and insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) in DDP-sensitive and DDP-resistant EC tissues and EC cells was determined by quantitative real-time PCR (qRT-PCR). The expression of apoptosis-related proteins, drug resistance-related proteins and IGF2BP1 proteins were detected by western blot. The half-maximal inhibitory concentration (IC50) of DDP was determined using a cell counting kit-8 (CCK-8) assay. For functional assays, cell proliferation, migration, invasion and cell apoptosis were determined using 5-ethynyl-2'-deoxyuridine (EdU) assay, wound healing assay, transwell assay and flow cytometry assay, respectively. The binding relationship between miR-145-5p and circ_0005667 or IGF2BP1 was verified by dual-luciferase reporter assay. A xenograft experiment was applied to clarify the functional role of circ_0005667 in vivo. RESULTS Levels of circ_0005667 and IGF2BP1 were markedly increased, whereas miR-145-5p was downregulated in DDP-resistant EC tissues and cells. The circ_0005667 deficiency could enhance DDP sensitivity, inhibit cell proliferation, migration and invasion and promote cell apoptosis in DDP-resistant EC cells in vitro. Mechanistically, circ_0005667 modulated IGF2BP1 expression through sponging miR-145-5p. In addition, miR-145-5p depletion attenuated circ_0005667 silencing-induced effects in EC cells. The regulation of miR-145-5p in DDP resistance involved low IGF2BP1 expression. In vivo experiments revealed that circ_0005667 silencing could improve the sensitivity of the tumor to DDP. CONCLUSION Circ_0005667 enhanced DDP resistance in EC by elevating IGF2BP1 through sponging miR-145-5p.

Abstract
PURPOSE Bladder carcinoma (BLCA) is the most common urinary tract malignancy and exhibits a poor response to chemotherapy. Protein phosphatase 2A (PP2A) is a serine/threonine phosphatase involved in a wide variety of regulatory cellular processes, including apoptosis and the DNA-damage response (DDR). LB100, a small molecule inhibitor of PP2A, has been shown to act as a chemo-sensitizer in multiple types of cancer. However, the anti-tumor effect and mode of action of LB100 in BLCA have yet to be identified. METHODS In vitro and in vivo experiments were performed to assess the anti-tumor effect of LB100 alone or in combination with gemcitabine. Mass spectrometry (MS)-based phosphoproteomics analysis was used to identify the downstream substrates of PP2A and to explore the mechanism underlying LB100-induced DNA damage and apoptosis. In addition, we established a chemo-resistant BLCA cell line (RT-112-R) by prolonged drug exposure and determined the effect of LB100 in enhancing genotoxicity in BLCA cell lines and xenograft mouse models. RESULTS We found that LB100 is sufficient to induce an anti-tumor response in BLCA cells by inducing DNA damage and apoptosis both in vitro and in vivo. Furthermore, we found that PP2A potentially dephosphorylates p-p21-ser130 to stabilize p21. Inhibition of PP2A by LB100 increased the level of p-p21-ser130, subsequently leading to a reduction in p21 level in a dose-dependent manner. In addition, we found that treatment of LB100 abrogated the G1/S cell cycle checkpoint, resulting in increased phosphorylation of γH2AX in BLCA cells. Moreover, LB100 enhanced genotoxicity in chemo-resistant BLCA cells by inducing DNA damage and apoptosis in vitro and in vivo. CONCLUSION Our findings indicate that PP2A may serve as a potential therapeutic target in BLCA through regulating p21 stability.

Abstract
RATIONALE & OBJECTIVE Patients with chronic kidney disease (CKD) may be at increased risk for cancer. CKD may also be associated with worse cancer outcomes. This study examined cancer incidence and mortality across the spectrum of CKD. STUDY DESIGN Population-based cohort study. SETTING & PARTICIPANTS All adult Ontario residents with data on estimated glomerular filtration rate (eGFR) or who were receiving maintenance dialysis or had received a kidney transplant (2007-2016). EXPOSURE Patients were categorized as of the first date they had 2 eGFR assessments or were registered as receiving maintenance dialysis or having received a kidney transplant. eGFR levels were further categorized as ≥60, 45-59, 30-44, 15-29, and <15 mL/min/1.73 m2; the latter 4 groups are consistent with KDIGO (Kidney Disease: Improving Global Outcomes) CKD categories G3a, G3b, G4, and G5, respectively. OUTCOMES Overall and site-specific cancer incidence and mortality. ANALYTICAL APPROACH Fine and Gray subdistribution hazard models. RESULTS Among 5,882,388 individuals with eGFR data, 29,809 receiving dialysis, and 4,951 having received a kidney transplant, there were 325,895 cancer diagnoses made during 29,993,847 person-years of follow-up. The cumulative incidence of cancer ranged between 10.8% and 15.3% in patients with kidney disease. Compared with patients with eGFR ≥60 mL/min/1.73 m2, adjusted hazard ratios (AHRs) for a cancer diagnosis among patients with CKD G3a, G3b, G4, and G5 were 1.08 (95% CI, 1.07-1.10), 0.99 (95% CI, 0.97-1.01), 0.85 (95% CI, 0.81-0.88), and 0.81 (95% CI, 0.73-0.90), respectively. The AHRs for patients receiving dialysis and who had received a transplant were 1.01 (95% CI, 0.96-1.07) and 1.25 (95% CI, 1.12-1.39), respectively. Patients with kidney disease had higher proportions of stage 4 cancers at diagnosis. Patients with CKD G3a, G3b, and G4 and transplant recipients had increased risks of cancer-specific mortality (AHRs of 1.27 [95% CI, 1.23-1.32], 1.29 [95% CI, 1.24-1.35], 1.25 [95% CI, 1.18-1.33], and 1.48 [95% CI, 1.18-1.87], respectively). The risks of bladder and kidney cancers and multiple myeloma were particularly increased in CKD, and mortality from these malignancies increased with worsening kidney function. LIMITATIONS Possible unmeasured confounding and limited ability to infer causal associations. CONCLUSIONS Cancer incidence in the setting of kidney disease is substantial. Cancer risk was increased in mild to moderate CKD and among transplant recipients, but not in advanced kidney disease. Cancer-related mortality was significantly higher among patients with kidney disease, particularly urologic cancers and myeloma. Strategies to detect and manage these cancers in the CKD population are needed.

Abstract
Cisplatin spearheads the anticancer chemotherapeutics in present-day use although acute toxicity is its primary impediment factor. Among a plethora of experimental medications, a drug as effective or surpassing the benefits of cisplatin has not been discovered yet. Although Oxaliplatin is considered more superior to cisplatin, the former has been better for colorectal cancer while cisplatin is widely used for treating gynaecological cancers. Carcinoma imposes a heavy toll on mortality rates worldwide despite the novel treatment strategies and detection methods that have been introduced; nanomedicine combined with precision medicine, immunotherapy, volume-regulated anion channels, and fluorodeoxyglucose-positron emission tomography. Millions of deaths occur annually from metastatic cancers which escape early detection and the concomitant diseases caused by highly toxic chemotherapy that causes organ damage. It continues due to insufficient knowledge of the debilitative mechanisms induced by cancer biology. To overcome chemoresistance and to attenuate the adverse effects of cisplatin therapy, both in vitro and in vivo models of cisplatin-treated cancers and a few multi-centred, multi-phasic, randomized clinical trials in pursuant with recent novel strategies have been tested. They include plant-based phytochemical compounds, de novo drug delivery systems, biochemical/immune pathways, 2D and 3D cell culture models using small molecule inhibitors and genetic/epigenetic mechanisms, that have contributed to further the understanding of cisplatin's role in modulating the tumour microenvironment. Cisplatin was beneficial in cancer therapy for modulating the putative cellular mechanisms; apoptosis, autophagy, cell cycle arrest and gene therapy of micro RNAs. Specific importance of drug influx, efflux, systemic circulatory toxicity, half-maximal inhibition, and the augmentation of host immunometabolism have been identified. This review offers a discourse on the recent anti-neoplastic treatment strategies to enhance cisplatin efficacy and to overcome chemoresistance, given its superiority among other tolerable chemotherapies.

Abstract
Cisplatin-based neoadjuvant chemotherapy (NAC) followed by radical cystectomy is the standard treatment for patients with muscle-invasive bladder cancer (MIBC). However, the implementation of NAC is lower than desirable mainly due to its limited impact on overall survival, patients' comorbidities and the lack of predictive biomarkers to select those patients most likely to benefit from NAC. In the last decade, improved molecular MIBC characterisation, the identification of potential predictive and prognostic biomarkers as well as the incorporation of new effective therapies with a better toxicity profile, such as immunotherapy, has changed the treatment paradigm for MIBC. Therefore, the main goal for the near future is to introduce these clinical and translational advances into routine clinical practice to personalise treatment for each patient and increase the opportunity to implement bladder preservation strategies. The present review focuses on the current status of NAC in MIBC, unsolved questions and future therapeutic approaches.

Abstract
Background There is a lack of research on the molecular interaction of the enhancers of rudimentary homolog (ERH) in bladder cancer (BC) cells. This study aimed to determine the interacting proteins of ERH in human T24 cells. Methods First, the ERH gene was overexpressed in human T24 cells. Coimmunoprecipitation (co-IP) and shotgun mass spectrometry (MS) analyses were performed to obtain a list of proteins that interact with ERH. Subsequently, bioinformatic analyses with Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and protein–protein interaction (PPI) studies were performed to analyze the ERH-interactive protein list (ERH-IPL). Then, we selected one of the interacting proteins, EIF2α for verification. An immunofluorescence colocalization assay was performed to validate the co-expression of the selected protein, and the binding sites of the two proteins were predicted by ZDOCK technology. Finally, PCR analysis on the downstream molecules of the interacting protein was performed for verification. Results ERH protein was successfully overexpressed in human T24 cells. We obtained a list of 205 proteins that might directly or indirectly interact with the ERH protein by mass spectrometric analysis. The bioinformatic analysis showed that ERH-interacting proteins were related to “ribonucleoprotein complex”, “ATPase activity”, “nuclear speck”, and “translation factor activity, RNA binding”. We further identified one of the key genes, EIF2S1, and confirmed that the corresponding protein EIF2α is co-expressed and may bind with ERH in human T24 cells. The mRNA levels of molecules ATF4 and CHOP were found to be upregulated by ERH. Conclusion ERH protein affects “ribonucleoprotein complex”, “ATPase activity”, “nuclear speck”, and “translation factor activity, RNA binding”. The ERH protein can interact with EIF2α and regulate the EIF2α-ATF4/CHOP signaling pathway in human T24 cells.

Abstract
Background Bladder cancer is one of the top 10 cancers diagnosed in Americans with a median age of 73. This is the patient population that tends to be older with multiple medical conditions, and previously described variability in treatment in the earlier stages of the disease. This study aimed to evaluate the first-line therapeutic choices for older adults newly diagnosed with advanced bladder cancer. In addition, this work evaluated predictors of response as well as the role of events of functional importance in relation to treatment assignment. Methods A population-based cohort study was conducted using the SEER-Medicare database of patients with advanced stage bladder cancer not eligible for curative intent therapy between 2010 and 2013. Patient groups of interest were compared via univariate and multivariate associations. Additionally, a latent class analysis was applied to identify classes with similar features in reference to events of functional importance-events linked to the maintenance or improvement of physical function status. Results Within the sample, we noted that a minority of patients received a standard cisplatin-containing regimen (14.77%) and a majority did not receive any chemotherapy (59.69%). Most patients were over age 75. The adjusted odds ratio of no chemo versus cisplatin in patients aged 76 and older compared to patients 66-75 was 6.61 (4.79-9.13; p < 0.0001). We applied latent class analysis methods to the dataset, and three classes demonstrated very low and moderate levels of functional events in the 12 months prior to a person's first outpatient visit for advanced bladder cancer care. Conclusions Patients with new diagnosis of advanced bladder cancer largely do not receive the recommended first-line systemic therapy of cisplatin chemotherapy, and a significant majority does not receive any treatment. When evaluating the association between class assignment and predictors of chemotherapy use, such as comorbidity and age, patients with "low usage overall" were more likely to receive chemotherapy. Yet even patients who received chemotherapy had some events of functional importance.

Abstract
Emerging studies showed that α-hederin induced autophagic cell death in different cancers via reactive oxygen species. Nevertheless, α-hederin role in non-small-cell lung cancer (NSCLC) remains unknown. So, the aim of this study was to explain whether ferroptosis is a therapeutic strategy to NSCLC, and to explore the effect of α-hederin on NSCLC ferroptosis. Current investigation found that α-hederin inhibited NSCLC cell proliferation, invasion, and migration in vitro and in vivo at toxic doses. The α-hederin treatment also increased NSCLC cell chemosensitivity to cisplatin and promoted ferroptosis and apoptosis at a safe dose. Proteomics, metabolomics, and high-throughput sequencing detection confirmed that α-hederin treatment downregulated glutathione peroxidase 2 (GPX2), and glutathione synthase (GSS) expression suppressed the synthesis of glutathione (GSH), which destroyed the GSH redox system. Eventually, it led to ferroptosis, apoptosis, and membrane permeabilization in NSCLC. Taken together, the study provided molecular data to confirm that α-hederin induced ferroptosis, apoptosis, and membrane permeabilization in NSCLC by destroying the GSS/GSH/GPX2 axis-mediated GSH oxidation-reduction system at a safe and low-toxicity dose.

Abstract
Muscle-invasive bladder cancer (MIBC) is an aggressive disease requiring active management. Neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) is considered the standard treatment paradigm for MIBC patients, which could result in significant perioperative mortality and morbidity, as well as the significant alteration of the quality of life (QOL). Notably, multimodal bladder-preserving treatment strategies have been recommended for highly selected patients. Pathologic complete response (pCR) after NAC is a powerful prognostic indicator of survival for patients with MIBC. Clinical complete response (cCR) is then introduced as a complementary endpoint for pCR to assess disease status preoperatively. Bladder preservation strategy for patients who achieve cCR following NAC is emerging as a new treatment concept. However, the efficiency of the conservative strategy remains controversial. In this state-of-the-art review, we discuss the advantages and limitations of cCR and the feasibility and safety of bladder preservation strategy in highly selected MIBC patients who achieve cCR following NAC. We conclude that a conservative strategy can be considered a reasonable alternative to RC in carefully selected cCR MIBC patients, leading to acceptable oncological outcomes.

Abstract
The rapid development of nanotechnology has generated numerous ideas for cancer treatment, and a wide variety of relevant nanoparticle platforms have been reported. Metal-organic frameworks (MOFs) have been widely investigated as an anti-cancer drug delivery vehicle owing to their unique porous hybrid structure, biocompatibility, structural tunability, and multi-functionality. MOF materials with catalytic activity, known as nanozymes, have applications in photodynamic and chemodynamic therapy. Nucleic acids have also attracted increasing research attention owing to their programmability, ease of synthesis, and versatility. A variety of functional DNAs and RNAs have been applied both therapeutically (gene-targeting drugs for cancer treatment) and nontherapeutically (used as modified materials to enhance the therapeutic effects of other nanomedicines). The combined use of MOFs and functional nucleic acids have been extensively investigated and has been associated with excellent tumor-suppressor activity in various treatment methods. In this review, we summarize the progress in the research and development of tumor therapy based on MOFs and nucleic acid delivery over recent years, focusing on the combinational use of different delivery and design strategies for MOF/therapeutic nucleic acid platforms. We further summarize the strategies for combining MOFs (universal carrier, functional carrier) and nucleic acids (therapeutic nucleic acids, nontherapeutic nucleic acids) and discuss the corresponding therapeutic effects in cancer treatment.

Abstract
OBJECTIVE To determine whether use of neoadjuvant chemotherapy (NAC) is associated with a higher risk of post-operative complications following radical cystectomy (RC) for bladder cancer (BCa). MATERIALS AND METHODS We retrospectively reviewed records of patients undergoing RC for non-metastatic urothelial BCa at 13 tertiary care centres from 2007-2019. Patients who received NAC ('NAC + RC' group) were compared with those who underwent upfront RC ('RC alone' group) for intra-operative variables, incidence of post-operative complications as per the Clavien-Dindo classification (CDC) and rates of re-admission and re-intervention. Multivariable logistic regression analysis was performed to determine predictors of CDC overall and CDC major (grade III-V) complications. We also analysed the trend of NAC utilization over the study period. RESULTS Of the 3113 patients included, 968 (31.1%) received NAC while the remaining 2145 (68.9%) underwent upfront RC for BCa. There was no significant difference between the NAC + RC and RC alone groups with regards to 30-day CDC overall (53.2% vs 54.6%, p = 0.4) and CDC major (15.5% vs 16.5%, p = 0.6) complications. The two groups were comparable for the rate of surgical re-intervention (14.6% in each group) and re-hospitalization (19.6% in NAC + RC vs 17.9% in RC alone, p = 0.2%) at 90 days. On multivariable regression analysis, NAC use was not found to be a significant predictor of 90-day CDC overall (OR 1.02, CI 0.87-1.19, p = 0.7) and CDC major (OR 1.05, CI 0.87-1.26, p = 0.6) complications. We also observed that the rate of NAC utilization increased significantly (p < 0.001) from 11.1% in 2007 to 41.2% in 2019, reaching a maximum of 48.3% in 2018. CONCLUSION This large multicentre analysis with a substantial rate of NAC utilization showed that NAC use does not lead to an increased risk of post-operative complications following RC for BCa. This calls for increasing NAC use to allow patients to avail of its proven oncologic benefit.

Abstract
Aldehyde dehydrogenase 6 family member A1 (ALDH6A1) is a highly conserved member of aldehyde dehydrogenase (ALDHs) family. Recent studies reveal that it broadly involved in tumorigenesis and drug metabolism in kinds of cancer. However, the critical role of ALDH6A1 in bladder cancer progression and cisplatin resistance of cancer cells are still poorly understood. In this study, we researched the significant function of ALDH6A1 in bladder cancer. Our results showed that ALDH6A1 exhibited a decreased expression in clinical bladder cancer tissues and bladder cancer cell lines. Stable ALDH6A1 knockdown not only could promote cell growth and colony formation in bladder cancer cells, but also enhance drug resistance to cisplatin treatment. On the contrary, we found the active transcript factor hepatocyte nuclear factor 4α (HNF4α, NR2A1) by alveriene could upregulate ALDH6A1 expression, significantly inhibit the cell growth and colony formation of bladder cancer cells, and improve cisplatin sensitivity of bladder cancer cells. Together, our results show that ALDH6A1 plays as a tumor suppressor in bladder cancer, which regulated by HNF4a. ALDH6A1 could be a promising diagnostic marker and treatment target in bladder cancer.

Abstract
In the area of non-platinum complexes, various complexes containing gold, copper, ruthenium, and palladium have shown a strong cytotoxic effect on different cancer cell lines. The aim of our study was to examine the cytotoxicity of the Pd(II) complexes (C1-C5) and the corresponding ligands (L1-L5) on the DU-145 prostate cancer cell line. Also, due to its clinical application, the cytotoxicity of cisplatin has been examined. Our findings showed that C1- C5 complexes and cisplatin show dose-dependent and strong cytotoxic effects against the DU-145 cell line in vitro. Furthermore, the results demonstrated that early apoptosis was induced by all five Pd(II) complexes. Also, the results showed that complexes C1, C3, and C5 induced G0/G1 phase arrest on DU- 145 cells. Pd(II) complex C2 induced S phase arrest, while C4 complex induced G2/M phase arrest on cancer cells. Additionally, all tested complexes significantly reduced the amount of antiapoptotic protein Bcl-2. Also, there was a significant increase in the concentration of proapoptotic Bax protein in DU-145 cells treated C1-C5 complexes. The results of our research demonstrated that Pd(II) complexes induced apoptosis via the mitochondrial pathway. Thus, it is crucial to further investigate the cytotoxicity of these Pd(II) complexes in vivo. Complex C2 might be a good candidate for a new generation of anticancer drugs.

Liu Q. Current Advances in N6-Methyladenosine Methylation Modification During Bladder Cancer. Front Genet 2022; 12:825109. [PMID: 35087575 PMCID: PMC8787278 DOI: 10.3389/fgene.2021.825109] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 12/22/2021] [Indexed: 12/14/2022] Open
Abstract
N6-methyladenosine (m6A) is a dynamic, reversible post-transcriptional modification, and the most common internal modification of eukaryotic messenger RNA (mRNA). Considerable evidence now shows that m6A alters gene expression, thereby regulating cell self-renewal, differentiation, invasion, and apoptotic processes. M6A methylation disorders are directly related to abnormal RNA metabolism, which may lead to tumor formation. M6A methyltransferase is the dominant catalyst during m6A modification; it removes m6A demethylase, promotes recognition by m6A binding proteins, and regulates mRNA metabolic processes. Bladder cancer (BC) is a urinary system malignant tumor, with complex etiology and high incidence rates. A well-differentiated or moderately differentiated pathological type at initial diagnosis accounts for most patients with BC. For differentiated superficial bladder urothelial carcinoma, the prognosis is normally good after surgery. However, due to poor epithelial cell differentiation, BC urothelial cell proliferation and infiltration may lead to invasive or metastatic BC, which lowers the 5-years survival rate and significantly affects clinical treatments in elderly patients. Here, we review the latest progress in m6A RNA methylation research and investigate its regulation on BC occurrence and development.

Liu Q. The emerging roles of exosomal long non-coding RNAs in bladder cancer. J Cell Mol Med 2022; 26:966-976. [PMID: 34981655 PMCID: PMC8831985 DOI: 10.1111/jcmm.17152] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Revised: 11/30/2021] [Accepted: 12/14/2021] [Indexed: 12/12/2022] Open
Abstract
Extracellular vesicles (EVs), especially exosomes, have been reported to play essential roles as extracellular messengers by transporting goods in various diseases, while their potential roles in bladder cancer (BC) still remain to be further studied. BC exhibits a high degree of chemoresistance and metastatic ability, which may be affected by cancer‐derived exosomes that carry proteins, lipids and RNA. To date, the most studied exosomal molecular cargo is long non‐coding RNA (lncRNA). Although there is increasing interest in its role and function, there is relatively little knowledge about it compared with other RNA transcripts. Nevertheless, in the past ten years, we have witnessed increasing interest in the role and function of lncRNA. For example, lncRNAs have been studied as potential biomarkers for the diagnosis of BC. They may play a role as a therapeutic target in precision medicine, but they may also be directly involved in the characteristics of tumour progression, such as metastasis, epithelial‐mesenchymal transition and drug resistance. Cancer cells are on chemotherapy acting. The function of lncRNA in various cancer exosomes has not yet been determined. In this review, we summarize the current studies about the prominent roles of exosomal lncRNAs in genome integrity, BC progression and carcinogenic features.

Refining neoadjuvant therapy clinical trial design for muscle-invasive bladder cancer before cystectomy: a joint US Food and Drug Administration and Bladder Cancer Advocacy Network workshop. Nat Rev Urol 2022; 19:37-46. [PMID: 34508246 DOI: 10.1038/s41585-021-00505-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/13/2021] [Indexed: 02/08/2023]
Abstract
The success of the use of novel therapies in the treatment of advanced urothelial carcinoma has contributed to growing interest in evaluating these therapies at earlier stages of the disease. However, trials evaluating these therapies in the neoadjuvant setting must have clearly defined study elements and appropriately selected end points to ensure the applicability of the trial and enable interpretation of the study results. To advance the development of rational trial design, a public workshop jointly sponsored by the US Food and Drug Administration and the Bladder Cancer Advocacy Network convened in August 2019. Clinicians, clinical trialists, radiologists, biostatisticians, patients, advocates and other stakeholders discussed key elements and end points when designing trials of neoadjuvant therapy for muscle-invasive bladder cancer (MIBC), identifying opportunities to refine eligibility, design and end points for neoadjuvant trials in MIBC. Although pathological complete response (pCR) is already being used as a co-primary end point, both individual-level and trial-level surrogacy for time-to-event end points, such as event-free survival or overall survival, remain incompletely characterized in MIBC. Additionally, use of pCR is limited by heterogeneity in pathological evaluation and the fact that the magnitude of pCR improvement that might translate into a meaningful clinical benefit remains unclear. Given existing knowledge gaps, capture of highly granular patient-related, tumour-related and treatment-related characteristics in the current generation of neoadjuvant MIBC trials will be critical to informing the design of future trials.

Abstract
OBJECTIVE This study aimed to assess the survival differences between cisplatin/etoposide versus carboplatin/etoposide chemotherapy regimens in the management of patients with extrapulmonary neuroendocrine carcinomas (NECs). METHODS Administrative cancer care databases in the province of Alberta, Canada, were reviewed, and patients with extrapulmonary NECs (including those with small cell and large cell neuroendocrine carcinomas) who were treated with either cisplatin/etoposide or carboplatin/etoposide, 2004-2019, were reviewed. Kaplan-Meier survival estimates were used to compare the survival outcomes according to the type of platinum agent, and multivariable Cox regression analysis was used to assess the impact of the type of platinum agent on overall survival outcomes. RESULTS A total of 263 eligible patients were included in this analysis. These include 176 patients who received cisplatin/etoposide and 87 patients who received carboplatin/etoposide. Using Kaplan-Meier survival estimates, patients treated with cisplatin had better overall survival compared to patients treated with carboplatin (p = 0.005). Multivariable Cox regression analysis suggested that the following factors were associated with worse overall survival: higher Charlson comorbidity index (HR: 1.17; 95% CI: 1.05-1.30), gastrointestinal primary site (HR: 1.55; 95% CI: 1.12-2.14), stage IV disease (HR: 1.75; 95% CI: 1.28-2.38), and use of carboplatin (HR: 1.40; 95% CI: 1.02-1.92). CONCLUSIONS The current study suggested that cisplatin/etoposide might be associated with better overall survival compared to carboplatin/etoposide among patients with extrapulmonary NECs. It is unclear if this is related to differences in inherent responsiveness to the 2 platinum agents or due to differences in comorbidity burden between the 2 treatment groups.

Abstract
Evidence has shown that patients with bladder cancer are diagnosed at a much older age compared with those with other cancers. Given that co-morbidities and frailty are prevalent in older patients with advanced bladder cancer, they are easily excluded from randomized controlled trials. As little evidence has been available regarding assessment tools for frailty, the management of those patients remains challenging. This weakness is strongly manifested in muscle-invasive bladder cancer. Despite radical cystectomy is the standard of care for bladder cancer, there is an extensive undertreatment of older adult patients with potentially curative muscle-invasive bladder cancer. However, it is also true that radical cystectomy is often unsuitable for vulnerable or frail patients. Bladder preservation using trimodality therapy has been utilized as an alternative option, but the appropriate selection criteria for trimodality therapy remain unclear. Cisplatin-based regimens have been the first choice for advanced disease among eligible patients. Moreover, immunotherapy appears to have similar benefits and tolerability in both older and younger patients. Furthermore, palliative or supportive interventions need to be initiated earlier in patients with metastatic disease. Accumulating evidence suggests that frailty may play a key role in the selection of treatment modalities. Older patients should be considered for standard treatment based on frailty and not chronological age. Moreover, older patients with bladder cancer need to undergo geriatric assessment for proper decision-making.

Abstract
INTRODUCTION AND OBJECTIVES Bladder cancer is primarily a disease of older age and little is known about the differences between patients diagnosed with bladder cancer at a younger versus older age. Our objectives were to compare bladder cancer specific survival in patients aged <50 versus those aged 50-70 at time of diagnosis. MATERIALS AND METHODS The Swedish bladder cancer database provided data on patient demographics, clinical characteristics and treatments for this observational study. Cox proportional hazard regression models were adjusted for appropriate variables. All analyses were stratified by disease stage (non-muscle-invasive bladder cancer and muscle-invasive bladder cancer. Furthermore, we compared the frequency of lower urinary tract infections within 24 months prior to bladder cancer diagnosis by sex and age groups. RESULTS The study included 15,452 newly-diagnosed BC patients (1997-2014); 1,207 (8%) patients were <50 whilst 14,245 (92%) were aged 50-70. Patients aged <50 at diagnosis were at a decreased risk of bladder cancer death (HR = 0.82, 95%CI: 0.68-0.99) compared to those aged 50-70. When stratified by non-muscle-invasive and muscle-invasive bladder cancer, this association remained in non-muscle-invasive patients only (<50, HR = 0.43, 95% CI: 0.28-0.64). The frequency of lower urinary tract infection diagnoses did not differ between younger and older patients in either men or women. CONCLUSIONS Patients diagnosed with non-muscle-invasive bladder cancer when aged <50 are at decreased risk of bladder cancer-specific death when compared to their older (50-70) counterparts. These observations raise relevant research questions about age-related differences in diagnostic procedures, clinical decision-making and, not least, potential differences in tumour biology.
