简要总结
The proposed project will examine how exercise counteracts metabolic disorders and type 2 diabetes through regulating gene expression. The project is highly relevant to public health because of the global pandemic of diabetes, obesity, and associated metabolic syndromes as well as the well-known metabolic benefit of physical exercise in correcting these disorders.
详细描述
Exercise is a first-line treatment for type 2 diabetes, and exerts its beneficial effects not only by burning off energy but also by causing prolonged metabolic changes through changing gene expression. Genes are our genetic materials and the expression of genes determines our biology. In our previous study in animals, we identified some factors that drive exercise-induced gene expression changes. Here we would like to address whether the result is also true in human. This work will provide molecular insights into how exercise remodels our metabolism and will potentially find a way to maximize the benefit we get from physical exercise.
The purpose of this study is to determine whether acute exercise activate certain molecular factors in human skeletal muscle. Participants will be asked to undergo an acute bout of aerobic exercise at ~ moderate intensity for about 2 hours. Before and after the exercise, the participants will undergo a muscle biopsy. The muscle tissues will be used for total RNA extraction and RT-qPCR analysis of genes that include but are not limited to de facto JunD/AP-1 target genes and will also be analyzed by Jun D Chip-qPCT to assess binding of Jun D on its de facto target genes.
