Across TCGA pan-cancer cohorts, TPRG1-AS2 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of TPRG1-AS2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where TPRG1-AS2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types TPRG1-AS2 is over-expressed in tumor.
KIRC, BRCA, and KICH are the cancer types where TPRG1-AS2 tumor–normal differential expression is most reproducible.
