Across TCGA pan-cancer cohorts, KLK10 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of KLK10’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where KLK10 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types KLK10 is over-expressed in tumor, although a few such as OV and LUAD show the opposite, repressed pattern.
PDAC, OV, and LUAD are the cancer types where KLK10 tumor–normal differential expression is most reproducible.
