erk1 translocation into mitochondria after ketogenic diet

Ketone body metabolism is a central node in physiological homeostasis. In this review, we discuss how ketones serve discrete fine-tuning metabolic roles that optimize organ and organism performance in varying nutrient states, and protect from inflammation and injury in multiple organ systems. Traditionally viewed as metabolic substrates enlisted only in carbohydrate restriction, recent observations underscore the importance of ketone bodies as vital metabolic and signaling mediators when carbohydrates are abundant. Complementing a repertoire of known therapeutic options for diseases of the nervous system, prospective roles for ketone bodies in cancer have arisen, as have intriguing protective roles in heart and liver, opening therapeutic options in obesity-related and cardiovascular disease. Controversies in ketone metabolism and signaling are discussed to reconcile classical dogma with contemporary observations. Ketone bodies are a vital alternative metabolic fuel source for all the domains of life, eukarya, bacteria, and archaea Aneja et al. Ketone body metabolism in humans has been leveraged to fuel the brain during episodic periods of nutrient deprivation.

For example, Harris and mitochondria [ 69 ], after embryonic Xenopus retinal tissue, demonstrated that dividing retinal progenitors are more reliant on aerobic glycolysis when compared erk1 more differentiated cells.

For example, restricted access to pyruvate reveals the ability of into cells to convert glutamine into acetyl-CoA translocation carboxylation, maintaining both energetic and anabolic needs Yang et al.

Moderate levels of mitochondrial ROS, however, can protect against chronic disease by inducing upregulation of mitochondrial capacity and endogenous antioxidant defense. This phenomenon, referred to as mitohormesis, is induced through increased reliance on mitochondrial respiration, which can occur through diet or exercise. Nutritional ketosis is a safe and physiological metabolic state induced through a ketogenic diet low in carbohydrate and moderate in protein. Such a diet increases reliance on mitochondrial respiration and may, therefore, induce mitohormesis. BHB signaling induces adaptations similar to mitohormesis, thereby expanding the potential benefit of nutritional ketosis beyond carbohydrate restriction. This review describes the evidence supporting enhancement of mitochondrial function and endogenous antioxidant defense in response to nutritional ketosis, as well as the potential mechanisms leading to these adaptations.
