Across TCGA pan-cancer cohorts, PLA2G12B mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of PLA2G12B’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where PLA2G12B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types PLA2G12B is over-expressed in tumor, although a few such as CCRCC and LSCC show the opposite, repressed pattern.
CCRCC and LSCC are the cancer types where PLA2G12B tumor–normal differential expression is most reproducible.
