Research has demonstrated that the inhibition of ALK4/5 effectively attenuates erastin-induced ferroptosis in HK-2 cells by potentiating Nrf2 signalling pathways (49) Previous studies have indicated that TGFBR1 expression was elevated in ectopic endometrium compared to eutopic endometrium in EMs patients (50). Here, ACVR1B is linked to eosinophilia-myalgia syndrome.
