Across TCGA pan-cancer cohorts, HMGB1P48 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of HMGB1P48’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where HMGB1P48 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types HMGB1P48 is over-expressed in tumor.
LUAD and LIHC are the cancer types where HMGB1P48 tumor–normal differential expression is most reproducible.
