Core Tip
Core Tip: Colorectal cancer (CRC) is insensitive to radiotherapy and has poor therapeutic efficacy, and there is an urgent need to find new therapeutic targets to prolong patient survival. 5-methoxytryptophan (5-MTP) is a tryptophan metabolite present in both animals and humans. 5-MTP has a wide range of physiological functions such as stabilizing endothelial function, anti-inflammation, and antioxidant to prevent cellular damage. Our study found that 5-MTP combined with an inhibitor of the PI3K/Akt/FoxO3a signaling pathway significantly promoted apoptosis and cell cycle arrest and inhibited cell proliferation in CRC cells compared with 5-MTP alone.
