Ko et al. studied the effect of pterostilbene on human oral cancer cells and found that pterostilbene can induce autophagy of oral cancer cells by activating JNK1/2, inhibiting Akt, ERK1/2 and p38, which is expected to be a new drug for the treatment of oral cancer [63]. The gene discussed is MAPK8; the disease is lip and oral cavity carcinoma.
