Upregulated METTL14 in human PCOS granulosa cells drives SLC7A11 m⁶A hypermethylation via a P53 RNA-binding cofactor, destabilizing SLC7A11 and promoting ferroptosis-linked inflammation.
- Why it matters: PCOS involves chronic inflammation and follicular arrest, but the molecular link to granulosa cell death is unclear.
- What they did: The study shows METTL14 is aberrantly upregulated in human PCOS GCs and correlates with oxidative damage, then uses AlphaFold3 modeling to support a METTL14–P53 complex that hypermethylates SLC7A11 mRNA.
- The result: In a DHEA-induced PCOS rat model, genetic ablation of Tp53 breaks this METTL14–P53–SLC7A11 axis, restoring redox balance, suppressing inflammation, and reversing the polycystic phenotype.
