Changes in Metabolites and Microbial Communities in Follicular Fluid Associated With Ovarian Function in Patients With Polycystic Ovary Syndrome

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Based on the integrated analysis of follicular fluid metabolites and microbial communities in patients with PCOS, this study reveals significant dysregulation in the follicular microenvironment. Key metabolites including D‐glucose and 25‐hydroxycholesterol show marked alterations, while microbial communities such as Alicyclobacillus and Terrimonas ...

A Novel Human Cellular System for Studying Normal Aging and for Anti‐Aging Discovery

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
This study introduces a human cellular aging model using placental trophoblasts (hTSC‐STBs) that mimics key aging features like senescence and genomic instability. It aligns with human tissue aging and responds to anti‐aging treatments, offering a scalable platform to screen potential therapies and bridge lab findings to clinical applications ...

Decreased PTGES2 Farnesylation in Granulosa Cells Compromises PGE2‐Dependent Cumulus Expansion and Oocyte Maturation During Ovarian Aging

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
A schematic showing decreased PTGES2 farnesylation in granulosa cells compromises PGE2‐dependent cumulus expansion and oocyte maturation during ovarian aging. In young ovaries, PTGES2 farnesylation of GCs regulates the process of cumulus expansion and oocyte maturation by facilitating PGE2 production.
