Across TCGA pan-cancer cohorts, H3P28 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of H3P28’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where H3P28 RNA is repressed in tumor relative to normal tissue. In most cancer types H3P28 is over-expressed in tumor, although a few such as KIRC show the opposite, repressed pattern.
KIRC and LUAD are the cancer types where H3P28 tumor–normal differential expression is most reproducible.
