GALNT7 and colorectal cancer: Given that our IHC analyses revealed an association between GALNT7-High status and increased Tn antigen expression, particularly in dMMR/MSI colorectal cancers (Fig. 3C, F, and K), we hypothesized that upregulated GALNT7 may directly influence glycan expression profiles, particularly by increasing Tn antigen levels on dMMR/MSI colorectal cancer cells, thereby contributing to cellular functions.
