Transcription factor involved in lipid metabolism

Transcription factors involved in lipid metabolism are a diverse group of proteins that regulate the expression of genes controlling the synthesis, storage, mobilization, and breakdown of lipids. Key families include peroxisome proliferator–activated receptors (PPARα, PPARγ, PPARδ), sterol regulatory element-binding proteins (SREBP-1a/-1c), forkhead box proteins (FOXA subfamily), liver X receptors (LXRα, LXRβ), hepatic nuclear factor 4 alpha (HNF4α), carbohydrate response element binding protein (ChREBP) and others. These transcription factors act as nutrient sensors—responding directly to fatty acids or their derivatives—and orchestrate complex gene networks that maintain metabolic homeostasis. They play central roles not only in physiological processes like adipogenesis but also contribute significantly to pathologies such as obesity, diabetes mellitus type II, non-alcoholic fatty liver disease (NAFLD) and cardiovascular diseases. Many are considered therapeutic targets for metabolic disorders; however, their broad biological functions across tissues present challenges for selective drug development without adverse effects.
