In another study, quantitative RT-PCR-verified endometriosis-specific serum-derived sEV-hsa-miR-26b-5p (downregulated), hsa-miR-215-5p (downregulated), and hsa-miR-6795-3p (upregulated) were found to be involved in the PI3K, MAPK, and protein kinase B (Akt) pathways in a KEGG analysis. Here, AKT1 is linked to endometriosis.
