MTOR and gastric cancer: There is growing evidence that it is significantly associated with tumorigenesis.37, 38 Recent studies have found that DDX5 stimulates the development of gastric cancer by activating mTOR signalling.4 Cross‐regulated colorectal tumorigenesis between mTOR signalling and O‐GlcNAcylation was recently reported.14 Interestingly, in the current study, there was no report that mTOR was modified by O‐GlcNAcylation.
