TLR4 and Insulin resistance: The results showed that the levels of gene and protein catalyzing lipogenesis were increased (SREBP1, ACC1 and FAS), while those catalyzing lipolysis were decreased (ATGL, HSL and ZAG), accompanied by dyslipidemia, insulin resistance and hepatic fat accumulation, and there were higher expression of TLR4 and NF-κB protein and lower expression of ERα protein in liver, and increased serum IL-17 and TNF-α levels in fructose and/or BPA exposed rats compared with controls.
