This study aimed to evaluate the potential cardioprotective effects of PARP inhibitors in patients with epithelial ovarian cancer treated with platinum-based chemotherapeutic agents. A retrospective cohort study was conducted using the Health Insurance Review & Assessment Service claims database from January 2007 to July 2022. Eligible patients were those diagnosed with ovarian, primary peritoneal, or fallopian tube cancer who received platinum-based chemotherapy after 2017. Propensity score matching was employed to adjust for potential confounders, and logistic regression and Cox proportional hazards regression analyses were utilized to estimate the odds ratios, hazard ratios, and 95% confidence intervals (CIs) for the occurrence of cardiac adverse events, including myocardial infarction, cardiomyopathy, and heart failure. A total of 7,253 eligible patients were included in the study, of which 233 (3.2%) used PARP inhibitors. After propensity score matching, no significant cardioprotective effect was observed in the PARP inhibitor-exposed group compared to the non-exposed group (adjusted odds ratio, 0.753; 95% CI 0.275-2.059; adjusted hazard ratio, 0.601; 95% CI 0.228-1.584). Although no statistically significant cardioprotective effect of PARP inhibitors was found in this study, there was a directional trend suggesting that patients with gynecologic malignancies treated with platinum-based chemotherapy could potentially benefit from PARP inhibitors. Further research with larger sample sizes and longer follow-up periods is warranted to elucidate the role of PARP inhibitors in mitigating cardiac adverse events in this patient population.</p>","PeriodicalId":14513,"journal":{"name":"Investigational New Drugs","volume":" ","pages":"243-249"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transiently increased blood bilirubin attributable to SCO-101 was observed in 12 cases (55%) and associated with jaundice in three patients. One and two DLTs, respectively, were observed at 150 and 250mg dosing-levels of SCO-101, and the MTD was determined to be 200 mg of SCO-101 daily for 6 days on a bi-weekly schedule together with 80% dose of Gem and Nab.

In A549 lung cancer cells, analysis revealed a significant downregulation of USP46 expression, while TRAF6 levels were notably elevated. These findings were corroborated by Western blotting, which confirmed the altered expression patterns. To further assess the implications of these changes, several experimental assays, including the Cell Counting Kit-8, transwell migration assays, and flow cytometry, were conducted to evaluate cell viability and apoptosis rates. Co-immunoprecipitation experiments demonstrated a direct interaction between USP46 and TRAF6, implicating USP46 in the modulation of TRAF6 ubiquitination, a process that is fundamental to tumor physiology. The results indicated that decreased USP46 expression led to an increase in the levels of the anti-apoptotic protein Bcl-2, while there was a corresponding decrease in key pro-apoptotic proteins such as caspase-3, caspase-9, and Bax. Additionally, the study found elevated levels of phosphorylated AKT and mTOR, which suggest the activation of survival signaling pathways in the cancer cells. These findings collectively suggest that the up-regulated USP46 promotes apoptosis in lung cancer cells through the regulation of TRAF6. Therefore, targeting the USP46/TRAF6 signaling pathway presents a promising therapeutic strategy for lung cancer treatment, potentially offering new avenues for intervention in cancer progression and cell survival mechanisms.</p>","PeriodicalId":14513,"journal":{"name":"Investigational New Drugs","volume":"43 2","pages":"328-336"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many GBM cases develop resistance to TMZ, resulting in a poor prognosis for patients, which underscores the urgent need for novel therapeutic approaches. One promising avenue is the inhibition of histone deacetylase 6 (HDAC6), an enzyme that deacetylates α-tubulin and is increasingly recognized as a potential pharmacological target in cancer. In GBM specifically, HDAC6 overexpression has been linked to poor prognosis and chemoresistance. In this study, we demonstrate that HDAC6 protein levels are elevated in GBM and evaluate the effects of the novel selective HDAC6 inhibitor, WT161, on U251, U87, and T98G cells to assess its potential to revert the malignant phenotype. Our results show a significant increase in acetylated α-tubulin levels, suppression of cell growth, cell cycle arrest at the G2/M phase, and decreased clonogenicity of 2D-cultured GBM cells. Additionally, WT161 acted synergistically with TMZ, induced apoptosis and enhanced TMZ-induced apoptosis. Notably, HDAC6 inhibition resulted in reduced cell migration and invasion, associated with decreased β-catenin levels. When cultured in 3D conditions, WT161-treated T98G spheroids were sensitized to TMZ and exhibited reduced migration. Finally, HDAC6 inhibition altered the metabolome, particularly affecting metabolites associated with lipid peroxidation.
