Across TCGA pan-cancer cohorts, C9orf135-DT RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of C9orf135-DT’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where C9orf135-DT RNA is repressed in tumor relative to normal tissue. In most cancer types C9orf135-DT is over-expressed in tumor, although a few such as KIRC and KIRP show the opposite, repressed pattern.
KIRC, KIRP, and KICH are the cancer types where C9orf135-DT tumor–normal differential expression is most reproducible.
