چکیده مقاله:
Objective(s): Menopause and diabetes obviously increase the risk of cardiovascular disease in women. The aims of the present study were to evaluate the effects of ovariectomy in type 2 diabetes on the histology and expression of miRNA-29, miRNA-133, IGF-1 and Bcl-2 genes and Bcl-2 protein and caspase 3 activity in the hearts of female rats. Materials and Methods: Forty Female Wistar rats were divided into four groups: control, sham, ovariectomized (OVX), and ovariectomized with type 2 diabetes (OVX.D). After the 8-week experiment, the histological evaluation of the heart tissue was performed using H&E staining and PAS analysis, and cardiac expression of miRNA-29, miRNA-133, IGF-1, and Bcl-2 were evaluated using real-time PCR, and Bcl-2 protein and caspase 3 activity were evaluated using Western blot and ELISA. Results: Ovariectomy significantly decreased miRNA-29, miRNA-133, IGF-1, and BCL-2 expression and Bcl-2 protein and increased caspase 3 activity in the heart compared to sham animals group (P

متن کاملExpression of the Mir-133 and Bcl-2 could be affected by swimming training in the heart of ovariectomized rats
Objective(s): The beneficial and more potent role of exercise to prevent heart apoptosis in ovariectomized rats has been known. The aim of this study was to examine the effects of swimming training on cardiac expression of Bcl-2, and Mir-133 levels and glycogen changes in the myocyte. Materials and Methods: Forty animals were separated into four groups as control, sham, ovariectomy (OVX) and o...
متن کاملThe role of microRNA-133 in cardiac hypertrophy uncovered.
Studies of microRNAs (miRNAs) have recently uncovered a new level of intricacy in the regulation of gene expression during organogenesis and pathogenesis.1 miR133, which is enriched in cardiac and skeletal muscle, is involved in cell specification,2 differentiation,3 and development.4 It is also downregulated during cardiac hypertrophy,5–7 which suggested that it may play a role in the underlyi...
