Abstract

One of the most prevalent metabolic diseases in recent years, type 2 diabetes is now one of the top causes of death globally and a significant risk factor for cardiovascular diseases. Therefore, the goal of this study is to investigate the impact of HIIT exercises on the levels of specific proteins associated with mitochondrial biogenesis and apoptosis in the heart tissue of male Wistar rats with type 2 diabetes. Animals in diabetic groups were given a high-fat diet and an intraperitoneal injection of STZ to cause diabetes. Following confirmation of the induction of diabetes, the exercise groups engaged in an 8-week HIIT exercise program. The current study’s findings show that in the heart tissue of diabetic rats, the creation of diabetes significantly raised P53 protein levels and significantly decreased SIRT1 protein levels. On the other hand, HIIT decreased P53 expression and raised SIRT1.

高强度间歇训练(HIIT)改善糖尿病大鼠心肌肥大和纤维化:P53和SIRT1的作用
2型糖尿病是近年来最普遍的代谢性疾病之一,目前是全球死亡的主要原因之一,也是心血管疾病的一个重要危险因素。因此,本研究的目的是研究HIIT运动对2型糖尿病雄性Wistar大鼠心脏组织中与线粒体生物发生和凋亡相关的特定蛋白质水平的影响。糖尿病组给予高脂肪饮食,并腹腔注射STZ致糖尿病。在确认诱发糖尿病后,运动组进行了为期8周的HIIT运动计划。目前的研究结果表明,在糖尿病大鼠的心脏组织中,糖尿病的产生显著提高了P53蛋白水平,显著降低了SIRT1蛋白水平。另一方面,HIIT降低P53表达,升高SIRT1。

期刊介绍: The Journal of Molecular Histology publishes results of original research on the localization and expression of molecules in animal cells, tissues and organs. Coverage includes studies describing novel cellular or ultrastructural distributions of molecules which provide insight into biochemical or physiological function, development, histologic structure and disease processes. Major research themes of particular interest include: - Cell-Cell and Cell-Matrix Interactions; - Connective Tissues; - Development and Disease; - Neuroscience. Please note that the Journal of Molecular Histology does not consider manuscripts dealing with the application of immunological or other probes on non-standard laboratory animal models unless the results are clearly of significant and general biological importance. The Journal of Molecular Histology publishes full-length original research papers, review articles, short communications and letters to the editors. All manuscripts are typically reviewed by two independent referees. The Journal of Molecular Histology is a continuation of The Histochemical Journal.
