AKT1 and endometriosis: Studies have shown that activation of the AKT and MAPK/Erk pathways not only promotes the proliferation and migration of endometrial stromal cells in endometriosis [28, 29] but also participates in the progesterone resistance of endometriosis [30], suggesting that the AKT and MAPK/Erk pathways are potential targets for endometriosis treatment.
