The discovery of novel, effective treatments is crucial to improving patient outcomes. Flavonoids, a diverse group of polyphenolic compounds found abundantly in fruits, vegetables, and medicinal plants, have garnered significant attention for their anticancer properties, including their potential role in ovarian cancer treatment. This comprehensive review explores the molecular mechanisms underlying the anticancer effects of flavonoids in OC, highlighting their ability to modulate key signaling pathways involved in cell proliferation, apoptosis, invasion, and metastasis. Flavonoids exert their effects through antioxidant activity, inhibition of angiogenesis, and regulation of tumor suppressor genes and growth factors. Additionally, they interact with cellular signaling molecules such as the PI3K/Akt/mTOR, MAPK, and NF-κB pathways, influencing cell survival and death. Notably, flavonoids also enhance the cytotoxicity of chemotherapeutic agents, making them valuable adjuncts in OC therapy. This review further discusses the pharmacokinetics, bioavailability, and potential challenges in the clinical application of flavonoids as therapeutic agents for ovarian cancer. The findings suggest that flavonoids, due to their multifaceted mechanisms of action and relatively low toxicity, hold promise as adjunct or alternative therapies in the treatment of ovarian cancer. Future clinical trials are essential to validate their efficacy and safety in human OC patients.</p>","PeriodicalId":51106,"journal":{"name":"Journal of Steroid Biochemistry and Molecular Biology","volume":" ","pages":"107116"},"PeriodicalIF":3.1,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148892738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emerging evidence identifies chronic hyperactivation of the mechanistic target of rapamycin (mTOR) signalling pathway as a central molecular driver of ovarian aging, promoting excessive ribosome biogenesis, impaired proteostasis, suppressed autophagy, mitochondrial dysfunction, and oxidative stress within oocytes and surrounding cumulus cells. Although rapamycin, the prototypical mTOR inhibitor, has demonstrated promising effects in improving ovarian function and in vitro fertilization outcomes, its teratogenic potential, immunosuppressive properties, metabolic side effects, and prolonged pre-conception washout requirements limit its clinical applicability in fertility management. This review synthesises current evidence on the role of mTOR in ovarian aging and is complemented by an original molecular docking analysis performed by the authors to evaluate the interaction between pentadecanoic acid and the mTOR kinase domain, an endogenous odd-chain saturated fatty acid, as a potential fertility-safe mTOR modulator. A comprehensive review of the literature was conducted using PubMed and related databases, encompassing pentadecanoic acid biochemistry, molecular mechanisms, mTOR signalling architecture, ovarian aging biology, rapamycin pharmacology, and molecular docking studies. Available evidence indicates that pentadecanoic acid activates AMP-activated protein kinase (AMPK), modulates PPAR-α/δ signalling, supports cellular antioxidant defence, and collectively attenuates anabolic mTOR activity while promoting autophagic recycling and metabolic homeostasis. Molecular docking analysis against the mTOR kinase domain (PDB ID: 4JSV) demonstrated that pentadecanoic acid binds within the active site with a binding energy of -4.4 kcal/mol through interactions with key hydrophobic residues, including Leu1936, Ile1939, Tyr2144, Val2227, and Gly2142, whereas rapamycin exhibited a stronger affinity (-10.1 kcal/mol). Unlike rapamycin, pentadecanoic acid is endogenously produced, compatible with pregnancy, and requires no washout period.

Aberrant activation or overexpression of EGFR has been observed in several cancers, including prostate cancer (PCa), and is associated with aggressive tumor behavior and poor prognosis. The development and progression of PCa largely depend on the involvement of androgen receptor (AR) pathways, which are directly related to EGFR signaling. Research indicates that EGFR can affect AR activity, increasing transcriptional activity or promoting ligand-independent activation, which may lead to castration-resistant prostate cancer (CRPC). Furthermore, emerging evidence suggests that estrogen receptors (ERs) may also interact with EGFR signaling in prostate tissue. These may influence tumor growth, interactions with cellular plasticity, and therapy resistance, but their exact mechanisms require further investigation. Identifying and improving treatment strategies for advanced and treatment-resistant PCa requires understanding the interplay between the EGFR, AR, and ER pathways. However, clinical trials have shown limited success in targeting EGFR alone, possibly through compensatory mechanisms via steroid hormone receptors. Therefore, therapies that simultaneously target EGFR and AR/ER activity may be more effective. Continued research into the molecular interplay between these pathways will broaden our understanding of prostate cancer biology and support the development of more personalized and effective treatments.

Bis(monoacylglycero)phosphate (BMP), also known as lysobisphosphatidic acid, is a unique phospholipid concentrated in the endolysosomal compartment, known to regulate vesicle dynamics, lysosomal enzyme activities, intracellular cholesterol trafficking and its oxidative metabolism. Using a validated model of BMP enrichment in murine RAW 264.7 macrophages, we investigated whether BMP could exert protective activity against 7KC-induced damage. Our findings revealed that BMP enrichment provides comprehensive protection against 7KC at the cellular level by preserving cell viability, morphology, and neutral lipid balance. Mechanistically, BMP enrichment prevented apoptosis by maintaining mitochondrial integrity and blocking caspase activation. This was demonstrated by normalized BAX/BCL2 ratios, preserved pro-Caspase-3 levels, and reduced PARP cleavage. Remarkably, BMP enrichment also restored autophagic flux, thereby preventing the pathological accumulation of LC3-II and p62 that characterizes autophagy dysfunction. Enhanced colocalization between LC3 and BMP suggests direct functional interactions in the stress response. Gene expression analysis confirmed that BMP enrichment normalized the transcriptional dysregulation of key autophagy regulators, including <em>Sqstm1</em>, <em>Becn1</em>, and <em>Pink1</em>.

However, the metabolism of primary steroids is not just a way of inactivating and excreting them, but generates a variety of metabolites with different biological properties. In this review, we outline how various active steroid metabolites were discovered, describe some of the ways they are generated, and how they can in a non-classical way act on receptors or alter the activity of steroid metabolizing enzymes, thereby indirectly affecting receptor activities. Examples include the 5α-reduced ring-A metabolites of 11-deoxycorticosterone (DOC) and progesterone that are formed in the brain, act as neurosteroids and exert effects through the GABA-A membrane receptor. Another example is 11-ketoprogesterone that potently activates mineralocorticoid receptors (MR), but not glucocorticoid receptors (GR), and is more potent than its 11β-hydroxylated form, in contrast to glucocorticoids. Moreover, we discuss the microbiome as important source of bioactive metabolites, exemplified by the 11β-hydroxylated 5α-reduced ring-A corticosteroid and progesterone metabolites that were shown as potent 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2) inhibitors. 11β-HSD2 inhibition results in cortisol-induced MR activation, sodium retention and hypertension. Furthermore, microbial 17,20-desmolase activity can convert glucocorticoids to androgens, potentially influencing diseases and therapeutic outcomes. There are still many knowledge gaps regarding bioactive steroid metabolites.
