Examining a previously published dataset of MYC-induced liver tumors30, we confirmed that SLC1A5 and SLC7A5 were induced by MYC and that turning MYC off rapidly abrogated their expression (Fig. 1d), thus indicating that SLC1A5 and SLC7A5 are likely direct MYC targets in liver cancer as shown for colon cancer13. This evidence concerns the gene SLC7A5 and liver cancer.
