Urokinase plasminogen activator receptor (uPAR) is a cell membrane glycosylphosphatidylinositol- (GPI-) anchored protein expressed in many cell types, for example, immune cells [92–94], endothelial cells [95], tumor cells [96], tubular epithelial cells [97], and podocytes [98]. This evidence concerns the gene PLAUR and neoplasm.
