The involvement of MMP-2 and MMP-9 in heart exercise-related angiogenesis

2013

Background Little is known about the involvement of matrix metalloproteinases (MMPs) in cardiac vascular remodelling induced by exercise. Our aim was to evaluate and localize MMP-2 and MMP-9’s activities in relation to capillary proliferation in mouse hearts trained for 15, 30 and 45 days. Methods Sixty-three mice were randomly assigned to 7 groups: four control sedentary groups (C0, C15, C30 and C45) and three groups trained by an endurance protocol (T15, T30 and T45). MMP-2 and MMP-9 were examined with zymography and immunostaining analyses. Capillary proliferation was evaluated counting the number of CD31-positive cells. Results Different activity patterns of the latent form of both MMPs…
