Across TCGA pan-cancer cohorts, H2AB1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of H2AB1’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where H2AB1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types H2AB1 is over-expressed in tumor.
ESCA and LIHC are the cancer types where H2AB1 tumor–normal differential expression is most reproducible.
