Across TCGA pan-cancer cohorts, RPH3AL mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RPH3AL’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where RPH3AL mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types RPH3AL is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.
PDAC and LUAD are the cancer types where RPH3AL tumor–normal differential expression is most reproducible.
