Across TCGA pan-cancer cohorts, ING1 mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of ING1’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where ING1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ING1 is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.
PDAC, LSCC, and LUAD are the cancer types where ING1 tumor–normal differential expression is most reproducible.
