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. This evidence concerns the gene PRELP and cancer.
