However, a lot of studies have reported that the inhibition of ferroptosis is ubiquitous in lung cancer cells; for example, xCT (SLC7A11), serine/threonine/tyrosine kinase 1 (STYK1), and iron–sulfur cluster biosynthetic enzyme (NFS-1) have been found to be highly expressed in NSCLC cells (18–20). This evidence concerns the gene SLC7A11 and lung cancer.
