Across TCGA pan-cancer cohorts, TTTY5 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of TTTY5’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where TTTY5 RNA is repressed in tumor relative to normal tissue. In most cancer types TTTY5 is over-expressed in tumor, although a few such as LUSC show the opposite, repressed pattern.
LUSC are the cancer types where TTTY5 tumor–normal differential expression is most reproducible.
