Across TCGA pan-cancer cohorts, PRXL2CP1 RNA differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of PRXL2CP1’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where PRXL2CP1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types PRXL2CP1 is over-expressed in tumor, although a few such as THCA and LUSC show the opposite, repressed pattern.
HNSC, READ, and THCA are the cancer types where PRXL2CP1 tumor–normal differential expression is most reproducible.
