Across TCGA pan-cancer cohorts, MARK2P5 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MARK2P5’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where MARK2P5 RNA is repressed in tumor relative to normal tissue. In most cancer types MARK2P5 is over-expressed in tumor, although a few such as KIRP and KIRC show the opposite, repressed pattern.
KIRP, KIRC, and THCA are the cancer types where MARK2P5 tumor–normal differential expression is most reproducible.
