Next, we conducted LASSO Cox regression with the 128 genes and obtained 11 robust genes (KLRB1, GZMH, SLC16A3, IMPDH1, IL15RA, MSC, S100A9, ST6GALNAC4, DAB2, ADA, SLC1A5) that were significantly correlated with the OS of HCC patients from TCGA-HCC dataset. Here, ST6GALNAC4 is linked to hepatocellular carcinoma.
