Discussion It is well known that bone loss diseases, such as osteoporosis Cd63 and rheumatoid arthritis, occur as a result of excessive bone resorption and bone remodeling imbalance correlated with increased catabolic processes and increased osteoclast activity [1, 2]. Enhanced osteoclast activity increases expression of MMP-9 which stimulates osteoclast reabsorption and degrades extracellular matrix proteins and collagen type I . This role of MMP-9 is well documented in studies with wild-type mice which showed an excellent correlation between MMP-9 and invasion of osteoclasts into the core of diaphysis . Moreover, studies on animal models also proved that MMP-9 can be a marker for osteoclast activity . Widely used ovariectomized rat model showed a substantial reduction in MMP9 activity lately, observed through gelatin zymography, after pharmacological treatment . Finally, human being tests confirmed the overexpression of MMP-9 in topics experiencing osteoporosis . Predicated on these known information, we hypothesized that smartly designed, managed, 12-week workout program might lead to the inhibition of osteoclasts activity from the downregulation of MMP9 activity. To check this hypothesis, we looked into adjustments in MMP-9 activity before and following the workout program using gelatin zymography like a molecular technique. Inside our study, we’ve tried to judge the response of enzyme activity of serum MMP-9 and TIMP-1 on suitable treatment in postmenopausal osteoporosis, which must include nonpharmacological and pharmacological therapy. Considering the part of bisphosphonates in regulating activation pathways for MMPs generally and in osteoporosis [27, 28], aswell as the need of proscribing sufficient workout program, SB 204990 we had been thinking about the part of supervised workout program in this rules, specifically. We suggested that nonpharmacological and pharmacological real estate agents, working together, could have the capability to modulate MMPs activity in an interval of three months. Studies on serum or plasma levels of gelatinase and their inhibitors showed an early release of MMP-9 after acute exercise of sufficient intensity, while data on TIMP-1 and the other MMPs were more contrasting. Most of the studies dealing with the effects of training indicated a trend toward reduction in blood gelatinase levels, once again more clear for MMP-9 which is in line with our results. The results were related to an anti-inflammatory effect of regular exercise and were more evident when training consisted of aerobic activities . A few data available about resistance exercise suggest opposite effects on gelatinase concentrations [7, 29, 30]. We reported decreased enzyme activity of MMP-9 (Figure 3), as well as increased TIMP-1 in the serum of female patients with postmenopausal osteoporosis, who had been involved in a 12-week exercise program, compared with those who have not got any physical activity treatment. These results point to the statistically significant reduction of the MMP-9/TIMP-1 ratio in EG (Figure 2).
