Moreover, CypA drives EMT and ovarian tumor growth and metastasis via a TAF15/STAT5A/miR‐514a‐3p pathway.[30] Although recent studies have established that CypA stabilizes NRF2 to drive lung cancer progression, the mechanisms linking CypA to ferroptosis regulation in chemotherapy‐resistant NSCLC remain unclear.[29] In this study, we identified significant upregulation of CypA in NSCLC tissues and confirmed its tumor‐promoting role. This evidence concerns the gene TAF15 and lung cancer.
