MT1DP, a lncRNA, enhances erastin‐induced ferroptosis in non‐small cell lung cancer (NSCLC) by downregulating NRF2 through stabilizing miR‐365a‐3p, leading to increased reactive oxygen species (ROS), malondialdehyde (MDA), ferrous iron, and decreased glutathione (GSH). Here, MT1DP is linked to lung cancer.
