Across TCGA pan-cancer cohorts, H3P45 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of H3P45’s most consistent transcriptional readouts.
The strongest signal is observed in cholangiocarcinoma (CHOL), where H3P45 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types H3P45 is over-expressed in tumor.
CHOL and LIHC are the cancer types where H3P45 tumor–normal differential expression is most reproducible.
