Abstract:
Fatty acid (FA) uptake is coordinated across tissues to maintain metabolic homeostasis, yet the mechanisms underlying tissue-specific regulation remain incompletely understood. NRAC has emerged as a nutrient-responsive, tissue-restricted factor enriched in adipose tissue and heart in both mice and humans. Mouse studies show that Nrac is dynamically regulated by feeding, fasting, and obesity in a tissue-specific manner. Recent work further shows that NRAC interacts with CD36 to regulate CD36-dependent FA uptake in adipocytes. Physiological studies support a role for NRAC in adipose lipid handling and systemic FA homeostasis, while human data link adipose NRAC expression to body fat distribution and circulating lipid traits. Together, current evidence identifies NRAC as an emerging regulator of tissue-specific FA metabolism and cardiometabolic health.
