Furthermore, the addition of glutamine also elevated c-Myc levels in various human cell lines, including HEK293T (human embryonic kidney cells), Caki-2 (human clear cell renal cell carcinoma), HepG2 (hepatoblastoma), A549 (human lung adenocarcinoma), and MCF7 and ZR-75-30 (human breast cancer) cells (Fig. 1C). Here, MYC is linked to clear cell renal carcinoma.
