Across TCGA pan-cancer cohorts, PPP1R3F mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of PPP1R3F’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where PPP1R3F mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types PPP1R3F is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.
PDAC are the cancer types where PPP1R3F tumor–normal differential expression is most reproducible.
