Key Points

The study aims to investigate how exosomal miR-125b-5p influences endometriosis by targeting specific signaling pathways.
Analysis of exosomal miR-125b-5p levels in endometriosis samples
Assessment of the relationship between miR-125b-5p and PI3K/Akt signaling pathways
Evaluation of the effects on endometrial stromal cell functions such as proliferation and migration.
High levels of exosomal miR-125b-5p correlate with endometriosis severity
miR-125b-5p downregulates PI3K/Akt signaling via VEGF
Inhibition of cell proliferation, migration, and invasion by miR-125b-5p.

Abstract

Exosomal miR-125b-5p was highly correlated with EMs, and it regulates the PI3K/Akt signaling pathways through VEGF to inhibit endometrial stromal cells proliferation, migration and invasion, acting as an important suppressing miRNA in endometriosis pathogenesis.
