Across TCGA pan-cancer cohorts, B4GALNT2 mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of B4GALNT2’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where B4GALNT2 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types B4GALNT2 is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
COAD are the cancer types where B4GALNT2 tumor–normal differential expression is most reproducible.
