In mice, 3-AR receptors mediate cold-induced thermogenesis (223) and pharmacological activation of 3-ARs acutely stimulate lipolysis leading to two-fold increase in energy expenditure, a dramatic ten-fold increase in insulin levels, and 4050% reduction in food intake (98)

Cell culture studies using adipocytes have shown that NNMT overexpression promotes lipid accumulation and insulin resistance, while NNMT knockdown or inhibition increases NAD+ levels, activates SIRT1, enhances mitochondrial respiration, promotes expression of thermogenic genes including UCP1, and drives white adipocyte browning toward a beige phenotype
