Across TCGA pan-cancer cohorts, H3P35 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of H3P35’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where H3P35 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types H3P35 is over-expressed in tumor.
LUSC are the cancer types where H3P35 tumor–normal differential expression is most reproducible.
