Description
Bradykinin is a peptide that exhibits natriuretic, antioxidative, vasodilatory, and pro-angiogenic activities. Bradykinin stimulates bradykinin receptors and increases PLC activity, decreasing ENaC open probability, inhibiting distal nephron Na+ transport, and inducing natriuresis. In vitro, bradykinin decreases H2O2-induced senescence, increases activity of superoxide dismutase (SOD), and suppresses DNA damage, ROS production, and NADPH oxidase activity. Additionally, bradykinin increases expression of VEGF and promotes tube formation in prostate cancer cells.
