ABSTRACT
Objective:
To investigate the impact and its possible mechanism of hydrogen sulfide (H2S) on myocardial collagen remodeling in experimental rats with diabetic mellitus (DM).Methods:
Rat’s DM model was established by intraperitoneal injection of STZ at 40 mg/kg. A total of 40 SD rats were randomly divided into 4 groupsControl group, DM group, DM+NaHS group, in which NaHS worked as exogenous donor of H2S and NaHS control group. n=10 in each group, all animals were treated for 8 weeks. The cardiac collagen deposition was observed by Masson staining, protein expressions of cardiac collagen types I, III, IV and transforming growth factorβ1 (TGF-β1), connective tissue growth factor (CTGF) were examined by Western blot analysis.Results:
Compared with Control group, DM group showed increased protein expressions of cardiac collagen types I and III, up-regulated expressions of TGF-β1 and CTGF, PConclusion:
H2S may improve the myocardial collagen remodeling in experimental DM rats, the mechanism might be related to the down-regulation of TGF-β1 and CTGF expression.
