Across TCGA pan-cancer cohorts, SYT5 mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of SYT5’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where SYT5 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types SYT5 is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.
PDAC are the cancer types where SYT5 tumor–normal differential expression is most reproducible.
