"Angiopoietin-2 (Ang-2) and vascular endothelial growth factor (VEGF) contribute to gastric cancer aggressiveness by up-regulating the expression of proteases. We evaluated the expression and the prognostic significance of angiogenic factors and proteases in 148 patients with R0-resected gastric cancer," scientists in Barcelona, Spain report. "Expression of VEGF, Ang-2, cyclooxygenase-2 (COX-2), urokinase-type plasminogen activator (uPA) and its inhibitor PAI-1, matrix metalloproteinases (MMP)-1 and -9 were assayed by immunohistochemistry.
