The combined treatment of 5-FU and resveratrol in colorectal cancer sensitizes tumor cells to 5-FU, which induces a further increase in oxidative stress related to the inhibition of the AKT and STAT3 proteins [119] known for their oncogenic potential in colorectal carcinomas [120].When resveratrol is combined with forskolin, it has phosphodiesterase 4D inhibitory effects to inhibit AKT/mTOR signaling in colorectal cancer cells [121]. Here, MTOR is linked to colorectal carcinoma.
