ARTICLE HIGHLIGHTS
Research background
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease, for which no effective therapeutic drugs have been approved. Huangqin decoction (HQD), a traditional Chinese medicine, has been widely used to treat liver diseases in clinical practice. Our study confirmed that HQD effectively mitigates high-fat diet (HFD)-induced hepatic inflammation. However, whether HQD has ameliorative effects on lipid metabolism disorders and insulin resistance, as well as the underlying mechanisms, remains unclear.
Research motivation
Convincing evidence for HQD in the clinical treatment of NAFLD is required.
Research objectives
This study aimed to investigate the therapeutic efficacy of HQD on lipid metabolism disorders and insulin resistance and explore the possible molecular mechanisms by focusing on the Sirt1/NF-κB pathway.
Research methods
High-performance liquid chromatography was used to identify the key components of HQD. HFD-induced NAFLD rats and palmitic acid-induced HepG2 cells were treated with HQD to investigate the mitigating effects of HQD on lipid metabolism disorders and insulin resistance. Finally, molecular biology techniques, including western blotting, immunohistochemistry, and immunofluorescence, were applied to explore the protein expression in the Sirt1/NF-κB pathway.
Research results
Ten key components of HQD were identified. The results showed that HQD effectively prevented lipid metabolism disorders in rats and HepG2 cells, inflammatory responses, and insulin resistance. Mechanistic exploration revealed that triggering Sirt1/NF-κB pathway-modulated lipogenesis and inflammation contributed to the favorable effects of HQD, which was further validated by the addition of EX-527 (a Sirt1 antagonist).
Research conclusions
Supported by our previous findings, we strongly believe that HQD is a promising complementary or auxiliary agent for the clinical treatment of NAFLD.
Research perspectives
HQD has been used to treat liver diseases in clinical practice for decades, with positive outcomes. More in-depth and precise research on the molecular mechanisms of HQD could guide and promote the clinical treatment of NAFLD more effectively.
