Troxerutin (TXR) is a bioflavonoid with demonstrated cardioprotective properties in various cardiac injury models, including cardioprotective effects in doxorubicin-induced myocardial injury, as well as diabetic myocardiopathy. This study, therefore, investigates whether TXR can mitigate PXT-induced cardiotoxicity and explores the underlying protective mechanisms. Male Wistar rats were treated with either PXT (7.5 mg/kg/week, i.p.) and/or TXR (150 mg/kg/day, oral) for 28 days. TXR restored the histological structure of the myocardial tissues, as well as heart weight and heart index, which were disrupted following PXT treatment. In addition, TXR alleviated PXT-induced elevation of cardiac damage indicators such as Troponin I and CK-MB. Furthermore, TXR counteracted the PXT effect on cardiac iron deposits and mitigated PXT-induced imbalance of redox homeostasis as evidenced by the abridged reactive oxygen species level, raised levels of the antioxidant enzymes glutathione peroxidase-4, catalase and superoxide dismutase, attenuating ferroptosis induced by PXT. Besides, TXR ameliorated PXT-induced endoplasmic reticulum (ER) stress as indicated by reduced ER stress markers C/EBP homologous protein, activating transcription factor-6, and glucose regulatory protein-78. Moreover, TXR hindered apoptosis induced by PXT, as evidenced by its effect on the BAX and BCL-2 expressions. Importantly, TXR did not abrogate the anticancer activity of PXT in cultured human MDA-MB cells. In conclusion, TXR hindered the cardiotoxicity of PXT and showed cardioprotective effects via its inhibitory actions on ER stress, ferroptosis, oxidative stress, and apoptosis.</p>","PeriodicalId":12004,"journal":{"name":"European journal of pharmacology","volume":" ","pages":"178944"},"PeriodicalIF":4.7,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856073","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}

To address this, we have performed both transcriptomic and proteomic large-scale approaches with breast cancer cell line models overexpressing HA-tagged ectopic XIAP (WT, H467A, ΔRING and NLS mutants) in distinct subcellular locations. Nuclear XIAP overexpressing cells (XIAP<sup>NLS</sup>) have been shown enriched for genes implicated in cellular processes other than apoptosis inhibition, such as proliferation, transport, locomotion, migration, cell motility, and protein phosphorylation. Interestingly, the validation analysis has shown differential expression of genes associated with the Wingless-related integration site (Wnt)/β-catenin pathway, as well as the insulin-like growth factor-binding protein 6 (IGFBP6) tumor suppressor gene. IGFBP6 transcript levels have been found reduced in XIAP<sup>NLS</sup>-overexpressing cells, as well as invasive breast cancer patients. Notably, IGFBP6 knockdown modulated long-term cell proliferation and doxorubicin sensitivity in cells overexpressing nuclear XIAP, further suggesting that nuclear XIAP might indirectly target the IGFBP6 pathway to promote chemoresistance. Finally, Wnt signaling effectors were identified in nuclear XIAP interactomes, closely linked to activation of β-catenin transcriptional activity in XIAP<sup>NLS</sup>-overexpressing cells.

Canonical transient receptor potential channel (TRPC) proteins are the crucial constituents of SOCCs.
