Hepatic and lipid metabolism pathways

Hepatic and lipid metabolism pathways encompass the complex network of biochemical reactions in the liver responsible for the synthesis, transport, and degradation of lipids such as cholesterol, triglycerides, and phospholipids (StatPearls, 2023). These pathways are essential for maintaining systemic energy homeostasis and providing the building blocks for cellular structures and signaling molecules (NCBI, 2022). The liver acts as a central hub, processing dietary fats and synthesizing endogenous lipids to meet the body's metabolic demands (StatPearls, 2023). Dysregulation of these pathways is central to the pathogenesis of metabolic diseases, including non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and cardiovascular disease (Nature Reviews Gastroenterology & Hepatology, 2021). Chronic lipid accumulation in hepatocytes can lead to lipotoxicity, inflammation, and eventually fibrosis or cirrhosis (PubMed, 2020). Pharmacological targeting of specific components within these pathways, such as HMG-CoA reductase or PPAR receptors, aims to correct lipid imbalances and reduce disease risk (PubMed, 2020). Because this term describes a broad physiological system rather than a single molecular entity, it is classified as a pathway rather than a specific therapeutic target.
