Nevertheless, 5-MTP combined with PI3K/Akt/FoxO3a signaling pathway inhibitors significantly promotedapoptosis and cell cycle arrest and inhibited cell proliferation in CRC cells compared with 5-MTP alone in ourstudy.CONCLUSIONTherefore, there is strong evidence that 5-MTP can be used as an effective medicine for CRC treatment.展开更多
