Despite its neuroprotective functions, the hippocampal repercussion of the estrogen receptor G protein-coupled estrogen receptor 1 (GPER1) in UE remains uncharted, alongside the prospective involvement of RUNX2. In Silico virtual screening suggested that prunetin (PRU) may activate GPER1 and inhibit RUNX2. To validate these findings in vivo, male Sprague Dawley rats were allocated into five groups: placebo-surgery (PS), PRU-treated PS, untreated UE, PRU-treated UE, and UE pretreated with G-15 (a selective GPER1 blocker) before PRU. Biochemically, PRU significantly restored hippocampal structure and behavioral functions impaired by UE, reduced serum IS levels, and replenished GPER1 expression. Additionally, it suppressed p-AKT, p-GSK3β, RUNX2, TLR4, and NF-κB, while enhancing cell survival by silencing the necroptotic signal (TICAM1/RIPK1/RIPK3/MLKL) and restoring caspase-8. PRU also counteracted mitochondrial dysfunction by downregulating PGAM5 and p-DRP-1. Crucially, these beneficial effects were nullified by G-15, confirming the role of activated GPER1 in mediating PRU's therapeutic effects. Collectively, PRU-induced GPER1 orchestrated neural integrity signal UE/AKT/GSK-3β/RUNX2, inflammatory axis UE/TLR-4/NF-κB, necroptosis pathway (TICAM1/RIPK1/RIPK3/MLKL), preventing mitochondrial dysfunction by suppressing the PGAM5/DRP-1 cue.

This situation calls for exploring new therapeutic options. One promising approach is drug repurposing, which uses existing medications with known effects to identify new anticancer agents. Isotretinoin (13-<i>cis</i>-retinoic acid), a vitamin A derivative typically used to treat severe acne, shows considerable potential as an anticancer agent. Recent studies suggest that isotretinoin has the potential to enhance the efficacy of cancer treatment and contribute to cancer inhibition by targeting specific molecular pathways. This review explores isotretinoin's chemistry, pharmacokinetics, and toxicity, emphasizing its role in cancer treatment through clinical and preclinical studies while elucidating its anticancer mechanisms. Both preclinical and clinical studies have revealed that isotretinoin can effectively inhibit the growth of tumor cells, induce apoptosis, and help regulate cellular differentiation in a range of cancers, including neuroblastoma, glioblastoma, breast, skin, lung, ovarian, cervical, and head and neck cancers. Isotretinoin works against cancer through several mechanisms. It activates retinoic acid receptors (RARs), suppresses oncogenic signaling pathways, and influences gene transcription related to cell cycle control and apoptosis. Moreover, combining isotretinoin with other treatments, like interferon-alpha, chemotherapy drugs, or other targeted inhibitors, can create synergistic effects that improve treatment effectiveness and potentially lessen side effects. Although isotretinoin holds great promise, we still need more research to address its limitations, such as its toxicity, risks during pregnancy, and differing responses in various cancer types. Current research focuses on optimizing isotretinoin-based therapies by refining dosage regimens to maximize efficacy and enhancing formulation strategies for improved absorption and reduced side effects. Ultimately, the use of isotretinoin in cancer treatment demonstrates the potential of repurposing established drugs and paves the way for more accessible and cost-effective cancer therapies.</p></div>","PeriodicalId":128,"journal":{"name":"Archiv der Pharmazie","volume":"358 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144929957","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}

Risk factors such as aging, poor lifestyle, and genetics significantly influence how these diseases progress, with oxidative stress being an important factor in their pathogenesis. Thioredoxin-interacting protein (TXNIP), a redox regulator, has emerged as a crucial mediator in oxidative stress-mediated CVD. TXNIP is a pro-oxidant that disrupts thioredoxin (TRX) antioxidant function and produces a redox imbalance that triggers vascular damage, endothelial dysfunction, and CVD progression. TXNIP has been shown to trigger the release of the proinflammatory cytokines IL-1β and IL-18, by activating inflammatory signaling through the NLRP3 inflammasome. By altering the interaction between TRX and ASK1, TXNIP regulates apoptosis and pyroptosis, which triggers cell death following oxidative stress.
