Across TCGA pan-cancer cohorts, OR2T3 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of OR2T3’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where OR2T3 RNA is repressed in tumor relative to normal tissue. In most cancer types OR2T3 is over-expressed in tumor, although a few such as KIRP and KICH show the opposite, repressed pattern.
KIRP, KIRC, and KICH are the cancer types where OR2T3 tumor–normal differential expression is most reproducible.
