PPIA and non-small cell lung carcinoma: To determine the role of the CypA/xCT axis in the ferroptosis of NSCLC, we performed rescue experiments and found that overexpression of SLC7A11 rescued CypA knockout‐induced ferroptosis, whereas knockdown of SLC7A11 in overexpression CypA cell lines conversely exacerbated ferroptosis (Figure 2J–L).
