Nrf2 Pathway Modulation in Hepatic Lipid Metabolism
Summary
The nuclear factor erythroid 2-related factor 2 (Nrf2) serves as a master regulator of hepatic redox balance and metabolic homeostasis. Under conditions of oxidative or electrophilic stress, Nrf2 dissociates from its cytoplasmic inhibitor, translocates to the nucleus and induces the expression of antioxidant and cytoprotective genes such as heme oxygenase-1 and NAD(P)H quinone dehydrogenase 1. Beyond its classical role in detoxification, Nrf2 exerts direct control over lipid handling by repressing lipogenic transcription factors (for example SREBP-1c) while enhancing fatty acid oxidation through upregulation of PPARα and associated enzymes. Crosstalk with energy-sensing kinases, notably AMPK, further links Nrf2 activity to improvements in insulin sensitivity and mitochondrial function. Pharmacological activation of Nrf2 has been shown to attenuate hepatic steatosis, reduce inflammation and mitigate endoplasmic reticulum stress, thereby slowing progression from simple lipid accumulation to steatohepatitis and fibrosis. These multifaceted actions highlight Nrf2 modulation as a promising therapeutic strategy for non-alcoholic fatty liver disease and related metabolic disorders.
