Across TCGA pan-cancer cohorts, PACRG-AS2 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of PACRG-AS2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where PACRG-AS2 RNA is repressed in tumor relative to normal tissue. In most cancer types PACRG-AS2 is over-expressed in tumor, although a few such as KIRC and THCA show the opposite, repressed pattern.
KIRC, KICH, and THCA are the cancer types where PACRG-AS2 tumor–normal differential expression is most reproducible.
