Further, we performed univariate Cox analysis (Supplementary Fig. 2C) on 71 FAGs extracted from TCGA-NSCLC and selected 8 FAGs with p < 0.1 in the results as candidate genes for the Lasso risk regression model (CDKN1A, PHKG2, ACSL3, GLS2, SAT1, FADS2, ACSL4 and NOX1). The gene discussed is GLS2; the disease is non-small cell lung carcinoma.
