Across TCGA pan-cancer cohorts, E2F4P1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of E2F4P1’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where E2F4P1 RNA is repressed in tumor relative to normal tissue. In most cancer types E2F4P1 is over-expressed in tumor, although a few such as LUSC and THCA show the opposite, repressed pattern.
LUSC and THCA are the cancer types where E2F4P1 tumor–normal differential expression is most reproducible.
