The angiogenesis-associated proteases Plat (tPA) and Dpp4 (DPP4), as well as the membrane serine protease Fap (FAP or seprase), which can be selectively expressed by tumor pericytes42,43, were amongst the serine proteases overexpressed in the QZ1-hi population (Fig. S24). This evidence concerns the gene PLAT and neoplasm.
