Mechanisms for the anti-obesity actions of bofutsushosan in high-fat diet-fed obese mice.

ABSTRACT:

Background

The Kampo medicine bofutsushosan (BTS; Pulvis ledebouriellae compositae; Fang Feng Tong Sheng San) has been used as an anti-obesity treatment in overweight patients. In this study, we assessed the underlying physiological changes induced by BTS in obese mice maintained on a high-fat diet.

Methods

Male ICR mice were fed a 60% kcal fat diet for 5 weeks starting at 4 weeks of age and then fed the same diet with administration of water (control) or aqueous BTS extract (1.0-2.0 g/kg) for 25 days. Body weight, wet weight of isolated white adipose tissue, and obesity-related serum parameters (glucose, lipids, leptin, adiponectin) were measured after treatment. The mRNA expression levels of leptin, adiponectin, and UCP1 in the adipose tissues were determined by quantitative real-time polymerase chain reaction after the first 5 days of treatment.

Results

Bofutsushosan (1.5-2.0 g/kg) significantly decreased total body weight and total wet weight of white adipose tissue isolated from subcutaneous (retroperitoneal) and visceral regions (epididymal, mesenteric, and perirenal). At 2.0 g/kg, BTS also decreased total fat mass, visceral fat mass, and ratio of fat mass to body weight as measured by computed tomography, and significantly decreased epididymal adipocyte size after 14 and 25 days' treatment. Twenty-five days' treatment lowered serum glucose, insulin, leptin, and triglycerides, and reduced homeostasis model assessment-insulin resistance. Alternatively, 2.0 g/kg BTS significantly increased mRNA levels of adiponectin, leptin, and UCP1 in interscapular brown adipose tissue but not epididymal white adipose tissue after 5 days' administration.

Conclusion

In the early administration period, BTS increased mRNA expression levels of leptin, adiponectin, and UCP1 in brown adipose tissues. With longer administration, BTS improved insulin resistance, and subsequently reduced serum levels of leptin and triglyceride in parallel with decreased visceral white adipose tissue volume and adipocyte size.

Project description:Blue honeysuckle (BH, Lonicera caerulea) is used as a traditional medicine in Russia, Japan and China, but is not commonly considered as an edible berry in Europe, USA or Korea. BH has been revealed to decrease serum cholesterol and triacylglycerol (triglyceride or TG) levels through the activation of AMP‑activated protein kinase (AMPK), thus it is expected to be a health functional food and pharmaceutical agent for the prevention of non‑alcoholic liver damage, in addition to effects as a suppressor of hyperlipidemia and as an anti‑obesity agent. In the present study, the pharmacological activity of BH extract (BHe) was observed in high‑fat diet (HFD)‑fed mice. Significant increases in fat pad weight, body weight, fat accumulation (body and abdominal fat density, and thickness of the periovarian and abdominal wall) and serum biochemical levels (aspartate transaminase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, γ‑glutamyltransferase, total cholesterol, low‑density lipoprotein and TG, with the exception of high‑density lipoprotein) were observed in HFD‑fed mice. In addition, increases in adipocyte hypertrophy, the area of steatohepatitis and hepatocyte hypertrophy were observed, whereas decreased zymogen content was identified upon histopathological observation. Increased deterioration of the endogenous antioxidant defense system (liver catalase, glutathione and superoxide dismutase) and hepatic lipid peroxidation was observed. In addition, there were decreases in hepatic glucokinase activity, AMPKα1 and AMPKα2 mRNA expression, adipose tissue uncoupling protein 2 expression, and adiponectin mRNA expression, increases in phosphoenolpyruvate carboxykinase and glucose‑6‑phosphatase activity, hepatic acetyl‑CoA carboxylase 1 mRNA expression, and the expression of leptin, CCAAT/enhancer‑binding protein (C/EBP) α, C/EBPβ and sterol‑regulatory‑element‑binding protein 1c mRNA in the periovarian tissue. Furthermore, non‑alcoholic fatty liver disease (NAFLD) and obesity were significantly inhibited by the continuous administration of BHe for 84 days. These results revealed that BHe may be a promising novel drug or functional food candidate for the treatment of obesity and NAFLD.
