One of its core pathologies is ovarian granulosa cell (GC) dysfunction, and ferroptosis, as a novel cell death mode dependent on iron ions and lipid peroxidation, may be involved in the PCOS process, but the exact mechanism is unknown. Plumbagin (PLB) shows potential in PCOS treatment due to its antioxidant properties. The present study aimed to elucidate the molecular mechanisms by which PLB ameliorates mitochondrial dysfunction and ferroptosis in PCOS GCs through the YTH N6-methyladenosine RNA binding protein 1/L-type amino acid transporter 1 (YTHDF1/SLC7A5) axis.</p><p><strong>Methods: </strong>An in vitro model of PCOS was constructed by treating KGN cells with dihydrotestosterone (DHT), and PLB treatment, YTHDF1 knockdown (si-YTHDF1), and SLC7A5 overexpression (pcDNA 3.1-SLC7A5) were intervened respectively. Cell viability was measured by cell counting kit-8. Lactate dehydrogenase (LDH) release, adenosine triphosphate (ATP) level, iron ion, and lipid peroxidation (LPO) content were detected by commercial kits. Mitochondrial membrane potential (MMP) was analyzed by JC-1 staining combined with flow cytometry. Reactive oxygen species (ROS) levels were assessed by C11-BODIPY probe, oxidative stress indicators including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase were measured by kits, and Cytochrome C, Ferritin, mitochondrial transcription factor A (TFAM), glutathione peroxidase 4 (GPX4) and SLC7A5 expression were detected by Western blot. Fluorescence in situ hybridization, RNA immunoprecipitation, and m6A quantitative real-time polymerase chain reaction verified the interaction and translational regulation of YTHDF1 and SLC7A5.</p><p><strong>Results: </strong>DHT treatment significantly decreased KGN cell viability, MMP and ATP levels, increased LDH release, ROS, MDA, iron ions and LPO content, up-regulated Cytochrome C expression, and down-regulated Ferritin, TFAM, and GPX4 expression. Both PLB treatment and YTHDF1 knockdown significantly reversed the above changes, but YTHDF1 overexpression reversed the protective effect of PLB. YTHDF1 co-localized with SLC7A5 mRNA and enhanced its translation through m6A modification. YTHDF1 knockdown reduced SLC7A5 protein levels without affecting mRNA expression. SLC7A5 overexpression weakened the protective effect of YTHDF1 knockdown, resulting in decreased cell viability, deterioration of mitochondrial function, and increased ferroptosis.</p><p><strong>Conclusion: </strong>PLB ameliorates DHT-induced mitochondrial dysfunction and ferroptosis in KGN cells by inhibiting YTHDF1 expression, and its action is dependent on the mechanism by which YTHDF1 regulates SLC7A5 translation through m6A modification. Downregulating YTHDF1 or SLC7A5 significantly enhances GC survival and function.</p>","PeriodicalId":16610,"journal":{"name":"Journal of Ovarian Research","volume":"18 1","pages":"115"},"PeriodicalIF":3.8,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12128246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serum concentrations of hormones including AMH, E2 and FSH, alongside oxidative stress-related biomarkers such as SOD, GSH-Px and MDA, were measured using ELISA. By counting the autophagosomes in granulosa cells using electron microscopy and LC3 immunofluorescence labeling, the degree of autophagy was assessed. Finally, detect the expression levels of genes and proteins related to autophagy.</p><p><strong>Results: </strong>LWDH elevated the ovarian weight and improved the ovarian index in mice with ovarian injury. The LWDH-treated group exhibited considerably lower MDA levels and significantly higher SOD and GSH-Px levels than the CTX group. Meanwhile, the group treated with LWDH reduced the granulosa cells' excessive apoptosis. In addition, the LWDH-treated group exhibited reduced LC3 fluorescence intensity and fewer autophagosome counts in comparison to the CTX group. Similarly, the expression of LC3, an autophagy-related marker, was decreased and p62 was markedly elevated in comparison to the CTX group. These findings suggest that LWDH has a positive protective effect on ovarian injury mice by increasing antioxidant enzyme activity, improving ovarian tissue pathological damage, inhibiting granulosa cell apoptosis, and balancing granulosa cell autophagy. In addition, the expression levels of SIRT1 and PI3K/AKT signaling pathway related proteins in the LWDH treatment group were significantly higher than those in the CTX group, suggesting that LWDH may exert its protective effect by activating the SIRT1/PI3K/AKT signaling pathway.</p><p><strong>Conclusion: </strong>LWDH may suppress granulosa cell autophagy through the activation of the SIRT1/PI3K/AKT signaling pathway, hence enhancing ovarian function.</p>","PeriodicalId":16610,"journal":{"name":"Journal of Ovarian Research","volume":"18 1","pages":"118"},"PeriodicalIF":3.8,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12131483/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
