TP63 and medical procedure: The consideration of the latter gene set as characteristic of prostatic basal epithelium relies on the facts that many of its member genes are known markers of basal cells of prostate glands and other stratified epithelia, such as those for tumor protein p63 (TP73L), keratin 5 (KRT5), keratin 7 (KRT7) and keratin 14 (KRT14), or laminin beta 3 (LAMB3) [18,19], and that they lack expression of markers of prostate malignancy such as alpha-methylacyl-coenzyme A racemase (AMACR, [20]) and hepsin (HPN, [21,22]).
