Song’s research on non-small cell lung cancer (NSCLC) found that there is ferroptosis in cancer cells treated with cisplatin, and ferroptosis-resistant cancer cells could secrete miR-4443 through exosomes, which increase the expression of FSP1 in ferroptosis-sensitive cancer cells, thereby enhancing the resistance of the cancer cells to ferroptosis [29]. The gene discussed is AIFM2; the disease is cancer.
