A significant inverse correlation was observed between changes in VEGF-A protein and miR-16 levels in eutopic endometrial and endometriotic cell cultures from women with endometriosis after treatment with peritoneal fluid (r = −0.525, P = 0.018 and r = −0.733, P = 0.001, respectively) (Figure 4). Here, VEGFA is linked to endometriosis.
