However, probiotic supplementation markedly decreased the intrahepatic lipid accumulation and steatosis histological score, which was associated with the downregulation of sterol regulatory element-binding protein-1 (SREBP1) and acetyl-CoA carboxylase (ACC) mRNA (p < 0.05) and the expression of its protein (p = 0.06). The gene discussed is SREBF1; the disease is steatosis.
