AMP-activated protein kinase, AMPK, is a conserved cellular energy sensor that responds to reduced cellular energy status and coordinates metabolism by increasing ATP-generating catabolic pathways while suppressing ATP-consuming anabolic processes. In metabolic disease research, the AMPK pathway is experimentally relevant because it regulates hepatic lipid synthesis, fatty acid oxidation, glucose production, skeletal-muscle glucose disposal, mTORC1-linked biosynthesis, autophagy, mitochondrial homeostasis, and whole-body energy balance. The central pathway logic is that energy stress, metformin, exercise-like stimulation, or direct AMPK activators increase AMPKα Thr172 phosphorylation and downstream substrate phosphorylation, including ACC and RAPTOR. Phosphorylation of ACC suppresses lipogenesis and supports fatty acid oxidation, whereas phosphorylation of RAPTOR suppresses mTORC1 signaling and links cellular energy status to growth and protein synthesis control. The pathway is linked
Metabolic Diseases
Metabolic diseases are a group of diseases related to abnormalities in the body's metabolic processes, including diabetes, obesity, hyperlipidemia, etc. These diseases typically involve disturbances in insulin, glucose, and lipid metabolism, leading to elevated blood glucose and lipid levels. Risk factors for metabolic diseases include poor eating habits, lack of exercise, genetics, etc. Approaches to managing metabolic disease include medications, lifestyle changes, and nutritional interventions. Early detection and comprehensive treatment are crucial to prevent complications and improve patient quality of life.
