E3 ubiquitin ligase PELI1 promotes ferroptosis in granulosa cells in PCOS by degrading Fth1

Key Points

• Ferroptosis is significantly increased in granulosa cells upon degradation of Fth1 by PELI1, suggesting a critical role in polycystic ovary syndrome.
• The study shows that elevated PELI1 levels correlate with decreased Fth1 expression in granulosa cells of women with polycystic ovary syndrome.
• Assessment of granulosa cells reveals that E3 ubiquitin ligase PELI1 directly impacts ferroptosis pathways through its activity on Fth1.
• This finding highlights a potential therapeutic target for managing polycystic ovary syndrome, although further research is needed.
