It is shown that mucin-type O-glycan biosynthesis is an important pathway of colon carcinogenesis through single-cell transcriptomic analysis.27 Additionally, it has been reported that N-acetylgalactosaminyltransferase 7 (GALNT7) is upregulated in prostate cancer and can enhance its proliferation by regulating the O-glycosylation of prostate cancer cells.28 This evidence concerns the gene GALNT7 and prostate carcinoma.
