Across TCGA pan-cancer cohorts, STH RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of STH’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where STH RNA is more highly expressed in tumor relative to normal tissue. In most cancer types STH is over-expressed in tumor.
KIRC and BRCA are the cancer types where STH tumor–normal differential expression is most reproducible.
