To investigate whether ferroptosis inducers have anticancer effects on NSCLC cells, the effects of the GPX4 inhibitor RSL3 and the SLC7A11 inhibitor erastin on cell viability were evaluated in various NSCLC cells, as well as in normal bronchus cells, BEAS2-B, using the MTT assay (Table 1). The gene discussed is GPX4; the disease is non-small cell lung carcinoma.
