Because obesity-induced UGT expression in mouse liver and the induction was associated with AhR, CAR, PPAR-α, PXR, Nrf2, and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) up-regulation,[10] this may have a significant impact on the metabolism of bilirubin at different stages of hypertriglyceridemia. The gene discussed is AHR; the disease is hypertriglyceridemia.
