Matrix metalloproteinases in exercise and obesity

Matrix metalloproteinases (MMPs) are zinc- and calcium-dependent endoproteinases that have the ability to break down extracellular matrix. The large range of MMPs' functions widens their spectrum of potential role as activators or inhibitors in tissue remodeling, cardiovascular diseases, and obesity. In particular, MMP-1, -2, and -9 may be associated with exercise and obesity. Thus, the current...

P 88: Matrix Metalloproteinases in Neuroinflammation

Matrix metalloproteinases (MMPs) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. MMPs have been demonstrated to increase the permeability of the blood–brain barrier (BBB) by degrading the c...

Endurance exercise activates matrix metalloproteinases in human skeletal muscle.

In the present study, the effect of exercise training on the expression and activity of matrix metalloproteinases (MMPs) in the human skeletal muscle was investigated. Ten subjects exercised one leg for 45 min with restricted blood flow and then exercised the other leg at the same absolute workload with unrestricted blood flow. The exercises were conducted four times per week for 5 wk. Biopsies...

Matrix metalloproteinases

What makes an MMP an MMP? They all have a conserved zinc-binding site in their catalytic domain (HEXGHXXGXXH), and the sequence PRCGVPD in the propeptide domain. The cysteine residue serves to anchor the propeptide to the catalytic zinc, suppressing enzymatic activity in a manner that is not unlike a thumb in an open mouth. Release of this interaction results in proteolytic activity. MMPs are a...
