SLC7A11 and cancer: Since the SLC7A11-GSH-GPX4 system is a classical intracellular ferroptosis-resistant system and ferroptosis resistance in cancer cells has been shown to be involved in chemoresistance in cancer cells 28, 29, we focused on the effects of miR-141-3p inhibitors on the SLC7A11-GSH-GPX4 system in cancer cells.
