ST8SIA3

Across TCGA pan-cancer cohorts, ST8SIA3 mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of ST8SIA3’s most consistent transcriptional readouts.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where ST8SIA3 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ST8SIA3 is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.

PDAC are the cancer types where ST8SIA3 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in ST8SIA3 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
