The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: cis-Diammine(1,1-cyclobutanedicarboxylato)platinum(II)(SMILESS: O=C1C2(CCC2)C(O[Pt]O1)=O.N.N,cas:41575-94-4) is researched.Recommanded Product: 600-05-5. The article 《Prognostic impact of Schlafen 11 in bladder cancer patients treated with platinum-based chemotherapy》 in relation to this compound, is published in Cancer Science. Let’s take a look at the latest research on this compound (cas:41575-94-4).
The utility of Schlafen 11 (SLFN11) expression as a predictive biomarker for platinum-based chemotherapy has been established for cancers from different histologies. However, the therapeutic relevance of SLFN11 in bladder cancer (BC) is unknown. Here, we examined the clinicopathol. significance of SLFN11 expression across 120 BC cases by immunohistochem. We divided the cases into two cohorts, one including 50 patients who received adjuvant or neoadjuvant platinum-based chemotherapy, and the other including 70 BC patients treated by surgical resection without chemotherapy. In the cohort of 50 BC cases treated with platinum-based chemotherapy, the SLFN11-pos. group (n = 25) showed significantly better overall survival than the SLFN11-neg. group (n = 25, P = .012). Schlafen 11 expression correlated significantly with the expression of luminal subtype marker GATA3. Multivariate analyses identified SLFN11 expression as an independent prognostic predictor (odds ratio, 0.32; 95% confidence interval, 0.11-0.91; P = .033). Conversely, in the cohort of 70 BC cases not receiving platinum-based chemotherapy, the SLFN11-pos. group (n = 29) showed significantly worse overall survival than the SLFN11-neg. group (n = 41, P = .034). In vitro analyses using multiple BC cell lines confirmed that SLFN11 KO rendered cells resistant to cisplatin. The epigenetic modifying drugs 5-azacytidine and entinostat restored SLFN11 expression and resensitized cells to cisplatin and carboplatin in SLFN11-neg. BC cell lines. We conclude that SLFN11 is a predictive biomarker for BC patients who undergo platinum-based chemotherapy and that the combination of epigenetic modifiers could rescue refractory BC patients to platinum derivatives by reactivating SLFN11 expression.
