OGA and colorectal cancer: O‐GlcNAcylation is well known to be dynamically regulated by OGT and OGA.22 To elucidate the exact mechanism by which O‐GlcNAcylation promotes the development of colorectal cancer, co‐immunoprecipitation (Co‐IP) analysis was performed in SW480 OGT‐Flag overexpressing cells using OGT and O‐GlcNAcylation antibodies (Figure 3C, D).
