What was done
This narrative review synthesizes published literature on the role of N6-methyladenosine (m6A) epitranscriptomic modification in the pathophysiology of polycystic ovary syndrome (PCOS). The authors summarize the dynamics of m6A regulatory proteins in folliculogenesis and examine findings from human granulosa cell studies and animal models of PCOS.
What was found
The abstract reports no numerical values or statistical metrics. It qualitatively notes that m6A methylation regulates mRNA stability, splicing, and translation during follicular and oocyte development. It reports that altered m6A methylation patterns and regulatory proteins in granulosa cells and ovarian tissues correlate with impaired oocyte maturation, hyperandrogenism, and increased immune cell infiltration.
Why it matters
It highlights an emerging post-transcriptional epigenetic layer in PCOS, helping explain how environmental and non-genetic factors may disrupt ovarian gene expression and folliculogenesis.
Limits
The review is non-systematic and does not report search methodology, sample sizes, or quantitative effect sizes. The reviewed mechanistic evidence relies primarily on animal models and isolated cell cultures rather than robust clinical outcomes.
