Across TCGA pan-cancer cohorts, PLEKHM2 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of PLEKHM2’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where PLEKHM2 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types PLEKHM2 is over-expressed in tumor, although a few such as LSCC and LUAD show the opposite, repressed pattern.
CCRCC, LSCC, and LUAD are the cancer types where PLEKHM2 tumor–normal differential expression is most reproducible.
