PRELP and neoplasm: Since the expression of PRELP has only been analyzed in some tumor types, like bladder, pancreatic, colorectal, hepatocellular carcinoma and retinoblastoma [30, 36, 38, 41, 67], PRELP expression was determined in different cancers using the two independent databases GENT2–U133Plus2 and GENT2–U133A consisting of 5.487 normal tissues and 35.806 cancer samples.
