In HONE-1, NUGC-3 and HepG2 carcinoma cells, tylophorine, which is extracted from Tylophora indica, has been reported to increase the dephosphorylated protein level of eEF2, thereby accumulating the protein level of c-jun and cyclin A, thus arresting the cell cycle at G1 phase [99]. This evidence concerns the gene EEF2 and carcinoma.
