Interestingly, SLC7A6 and SLC1A5 have been shown to be targets of driver genes implicated in tumorigenesis, such as c-Myc in breast cancer, lung small cell carcinoma, colorectal carcinoma, glioblastoma, and HCC [40,41,42,43,44,45]. This evidence concerns the gene SLC7A6 and hepatocellular carcinoma.
