White Radish polyphenols improve diet-induced obesity by regulating the metabolism of bile acids via gut-liver axis

引用

Food Science and Human Wellness 2024年

作者： xiong Geng Weina Tian Miaomiao Zhuang Rundong Wang Wenting Ma Ran Lin Huayan shang Zhangfu Yu Ronghu Shen Jianrong Li College of Food Science and Engineering， Bohai University Hangzhou Xiaoshan Agricultural Development CO.， Ltd

Natural plant or functional food-derived biologically active ingredients have recently raised considerable interest in their antiobesity effect. However， the antiobesity role of polyphenols of white radish roots remains unknown. This study examined the therapeutic efficacy and underlying mechanisms of polyphenols extract from white radish roots (RPE) on obese mice. RPE administration significantly decreased the weight gain in high-fat diet fed (HFD) mouse models. RPE intervention also increased serum glutathione transferase (GSH-Px) and superoxide dismutase (SOD) levels， and decreased malondialdehyde (MDA)， tumor necrosis factor-α (TNF-α) and lipopolysaccharide (LPS) levels in the HFD-fed mice. The intervention led to an escalation in the proportion of beneficial bacteria (Akkermansia， Clostridia)， and a corresponding decline in the fraction of harmful bacteria (Proteobacteria). According to liquid chromatography-mass spectrometry (LC-MS)-based gut metabolomics， the RPE intervention notably influenced several metabolic pathways， including those involved in protein digestion and absorption， central carbon metabolism related to cancer， and the biosynthesis of steroid hormones. Additionally， RPE treatment led to a reduction in the intestinal microbes possessing bile-salt hydrolase (BSH) activity， whereas increased the expression levels of the bile acid (BA) synthesis enzyme cholesterol 7α-hydroxylase (Cyp7a1). This led to increase hepatic production and fecal excretion of BAs， reduce hepatic cholesterol， and decrease lipogenesis. Treated HDF mice showed mitigation of hepatic steatosis and inflammation through gut-liver axis modulation by RPE interference. These findings together offer a significant understanding of the potential of RPE as an anti-obesity treatment and could assist in developing strategies for weight loss.

利用469份农户调查数据,探究农户购买农业保险对其节水灌溉技术采纳行为的影响,进而剖析农业风险转移效果评价和异质性风险偏好在其中的作用机理。研究显示:农业风险转移与降低工具呈现互补关系,具体表现为农户购买农业保险将直接促进节水灌溉技术的采纳,并将通过提高其农业风险转移效果评价间接促进节水灌溉技术的采纳。此外,道德风险和挤出效应将限制农业风险转移与降低工具互补性的发挥,表现为风险厌恶型农户购买农业保险将降低其采纳节水灌溉技术的可能性。为提高农户的风险抵御能力,需提升农业风险转移工具的保障效果,完善农村的普惠金融服务体系,降低农户采纳农业风险转移与降低工具的资金约束。同时,应协调农业风险转移与降低工具的关系,深入开展指导服务,实现农业保险与节水灌溉技术的协同推广,共同助力乡村振兴。
