In addition, miR‐15a‐3p increased the sensitivity of CRC cells to erastin and GPX4 and thus induced ferroptosis.[114] Overexpression of miR‐545 in CRC cells inhibited the expression of MDA, ROS, and Fe2+ and reversed the erastin‐ and RSL3‐induced decrease in CRC cell viability. Here, GPX4 is linked to colorectal carcinoma.
