代谢不灵活被定义为在不同能量底物之间切换的能力受损,是胰岛素抵抗和 2 型糖尿病 (T2DM) 的标志。因此,了解适当代谢灵活性的机制是防止代谢疾病发展和生理恶化的关键。影响代谢灵活性的重要下游参与者是线粒体。本综述的目的是描述线粒体代谢如何通过线粒体功能或生物发生的变化来适应有限的营养状况或热量过剩,并定义推动这些变化的机制。总而言之,这应该查明关键的调节点,通过这些点可以在代谢疾病的情况下改善代谢灵活性。
Metabolic inflexibility is defined as an impaired capacity to switch between different energy substrates and is a hallmark of insulin resistance and type 2 diabetes mellitus (T2DM). Hence, understanding the mechanisms underlying proper metabolic flexibility is key to prevent the development of metabolic disease and physiological deterioration. An important downstream player in the effects of metabolic flexibility is the mitochondrion. The objective of this review was to describe how mitochondrial metabolism adapts to limited nutrient situations or caloric excess by changes in mitochondrial function or biogenesis, as well as to define the mechanisms propelling these changes. Altogether, this should pinpoint key regulatory points by which metabolic flexibility might be ameliorated in situations of metabolic disease.
