Increased O-GlcNAcylation in colon cancer cells, either by OGT overexpression or OGA inhibition, reduces phosphorylation of AMPK at Thr172, activates mTOR and induces cell growth in vitro in LoVo cell line and in vivo in LoVo cell-derived tumors of BALB/c-nu/nu mice (52). This evidence concerns the gene MTOR and malignant colon neoplasm.
