Abstract/OtherAbstract:
OBJECTIVE: The present study was designed to explore the roles of MMP-2/TIMP-2 in cardiac fibrosis and to study the effects of benazepril, an angiotensin-converting enzyme inhibitor (ACEI) on cardiac remodelling in streptozotocin(STZ)-induced diabetic rats. METHODS AND RESULTS: Male Wistar rats were randomly divided into three groups: a normal control group (NC), a diabetes mellitus-untreated group (DM) and a diabetes mellitus benazepril-treated group (DB). Diabetes mellitus was induced in the DM and DB groups by intraperitoneal injection of streptozotocin (60 mg/kg). DB rats were treated with benazepril 10 mg/kg/day for 12 weeks by remedial perfusing of the stomach. In the DM group, compared with the NC group, the gene and protein expression of MMP-2 decreased while the TIMP-2 gene and protein expression increased in heart tissues, along with a markedly cardiac collagen deposition.All the above changes were attenuated by benazepril treatment in the DB group. CONCLUSIONS: The imbalance of MMP-2 and TIMP-2 expressions in heart tissues might participate in interstitial fibrosis in diabetic myocardiopathy. Benazepril may ameliorate cardiac fibrosis partly by regulating the MMP-2/TIMP-2 system.
