Abstract
The prevalence of chronic kidney disease (CKD) is increasing worldwide, making the disease an urgent clinical challenge. Caloric restriction has various anti-aging and organ-protective effects, and unraveling its molecular mechanisms may provide insight into the pathophysiology of CKD. In response to changes in nutritional status, intracellular nutrient signaling pathways show adaptive changes. When nutrients are abundant, signals such as mechanistic target of rapamycin complex 1 (mTORC1) are activated, driving cell proliferation and other processes. Conversely, others, such as sirtuins and AMP-activated protein kinase, are activated during energy scarcity, in an attempt to compensate. Autophagy, a cellular self-maintenance mechanism that is regulated by such signals, has also been reported to contribute to the progression of various kidney diseases. Furthermore, in recent years, ketone bodies, which have long been considered to be detrimental, have been reported to play a role as starvation signals, and thereby to have renoprotective effects, via the inhibition of mTORC1. Therefore, in this review, we discuss the role of mTORC1, which is one of the most extensively studied nutrient-related signals associated with kidney diseases, autophagy, and ketone body metabolism; and kidney energy metabolism as a novel therapeutic target for CKD.
