About this Research Topic
Non-insulin-dependent diabetes mellitus (NIDDM), obesity and their associated co-morbidities (heart failure, kidney disease, sarcopenia) are major health concerns in the world today. While numerous mechanisms have been proposed for this epidemic, it is well agreed upon that a lack of chronic physical exertion (exercise) in combination with consumption of a high fat western diet plays a causal role(s). Highlighting the importance of this idea, exercise in combination with diet are still considered front-line treatments for these diseases prior to pharmacological intervention. While exercise has a multitude of effects on different organ systems, an effect common to all tissues is an improvement in mitochondrial function which is pertinent as a loss of mitochondrial function has been noted in these diseases. However, an exact linkage between improved mitochondrial metabolism and insulin sensitivity remains elusive. Fully characterizing this linkage will enable new avenues of treatment for NIDDM and obesity.
This proposed Frontiers Research Topic seeks to identify data supporting a direct casual role of improved mitochondrial function in exercised induced improvements in insulin sensitivity in obesity and diabetes. Therefore, the goals of this proposal are to:
1. to provide a comprehensive overview of the data supporting a relationship between exercise induced improvements in insulin sensitivity and improved mitochondrial function;
2. to highlight the importance of mitochondrial function in metabolic diseases;
3. to present data describing the mechanisms whereby mitochondrial function affects insulin sensitivity;
4. to present data describing new state of the art techniques to investigate these relationships.
The scope of this proposed new Research Topic will be to provide an up to date assessment of the relationship between exercise induced improvements in insulin sensitivity and mitochondrial function, encompassing the areas of exercise physiology, pharmacology and endocrinology.
