Establishment of a prognostic gene signature for LUAD patients based on TGF-β signaling-related genes. A LASSO Cox regression was applied to screen the optimal parameter with cross-validation. B The coefficients for each gene during the training process. C The risk score of each LUAD patient in TCGA was ranked in ascending order, survival status, and heat map of 5 TGF-β signaling-related gene expression profiles
