RRP9

Across TCGA pan-cancer cohorts, RRP9 mass-spec protein differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of RRP9’s most consistent transcriptional readouts.

The strongest signal is observed in colon adenocarcinoma (COAD), where RRP9 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types RRP9 is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.

COAD, HNSC, and LSCC are the cancer types where RRP9 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in RRP9 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
