In a separate study, 22 endometriosis-related immune genes emerged from the overlap of 1 116 DEGs, featuring nine immune-related hub genes (BST2, CCL13, CD86, CSF1, FAM3C, GREM1, ISG20, PSMB8, S100A11) and nine ARG hub genes (GSK3A, HTR2B, RAB3GAP1, ARFIP2, BNIP3, CSF1, MAOA, PPP1R13L, SH3GLB2) (16). Here, PPP1R13L is linked to endometriosis.
