SLC7A11 and hepatocellular carcinoma: The heatmap showed an increased expression of CBS, FLT3, and GABARAPL1 in the low RS_Fe group and the increased expression of SLC1A5, SLC7A11, and MT3 in the high RS_Fe group (Fig. 2D), implying that these six genes might act as risk elements impacting the outcome of patients with HCC.
