Popis: Puerarin, an active ingredient of Pueraria lobata, has a range of pharmacological effects and excellent pharmacodynamic properties. In the present study, the effect of puerarin on angiotensin II-induced aortic aneurysm formation and the potential underlying molecular mechanisms were examined. The results revealed that puerarin significantly suppressed the viability, and induced the apoptosis, of aneurysm-inducing cells in a time- and dose-dependent manner. Furthermore, treatment with puerarin significantly suppressed the production of reactive oxygen species (ROS) and the expression of matrix metalloproteinase-2 (MMP-2) protein in aneurysm cells. Puerarin treatment significantly increased caspase-9 and −3 activity, induced the protein expression of phosphorylated (p)-Jun and inhibited the protein expression of activator protein 1 (AP-1) in aneurysm cells. It was also demonstrated that Puerarin significantly suppressed the reduced nicotinamide-adenine dinucleotide phosphate (NADPH) oxidase activity in aneurysm cells. Therefore, it was demonstrated that puerarin on suppressed the cell growth of angiotensin II-induced aortic aneurysm formation by affecting the rate of apoptosis, the generation of ROS, MMP-2, AP-1 and p-Jun protein expression and NADPH oxidase.
