Across TCGA pan-cancer cohorts, ASIC2 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ASIC2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where ASIC2 RNA is repressed in tumor relative to normal tissue. In most cancer types ASIC2 is over-expressed in tumor, although a few such as KIRC and READ show the opposite, repressed pattern.
KIRC, READ, and PAAD are the cancer types where ASIC2 tumor–normal differential expression is most reproducible.
