Across TCGA pan-cancer cohorts, ZPBP2 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of ZPBP2’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where ZPBP2 RNA is repressed in tumor relative to normal tissue. In most cancer types ZPBP2 is over-expressed in tumor, although a few such as LUSC and PRAD show the opposite, repressed pattern.
LUSC, PRAD, and ESCA are the cancer types where ZPBP2 tumor–normal differential expression is most reproducible.
