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