Furthermore, treating PCa cells with the O‐GlcNAcylation activator Thiamet G and the OGT inhibitor OSMI‐1, we proved that the addition of Thiamet G led to enhanced AR O‐GlcNAcylation, while OSMI‐1 induced a similar inhibitory effect as OGT knockdown (Figure 5C). This evidence concerns the gene OGT and posterior cortical atrophy.
