1Notoginsenoside Ft1 acts as a TGR5 agonist but FXR antagonist to alleviate high fat diet-induced obesity and insulin resistance in mice显示文摘Obesity and its associated complications are highly related to a current public health crisis around the world.A growing body of evidence has indicated that G-protein coupled bile acid(BA) receptor TGR5(also known as Gpbar-1) is a potential drug target to treat obesity and associated metabolic disorders.We have identified notoginsenoside Ftl(Ftl) from Panax notoginseng as an agonist of TGR5 in vitro.However,the pharmacological effects of Ftl on diet-induced obese(DIO) mice and the underlying mechanisms are still elusive.Here we show that Ftl(100 mg/100 diet) increased adipose lipolysis,promoted fat browning in inguinal adipose tissue and induced glucagon-like peptide-1(GLP-1) secretion in the ileum of wild type but not Tgr5^(-/-) obese mice.In addition,Ftl elevated serum free and taurineconjugated bile acids(BAs) by antagonizing Fxr transcriptional activities in the ileum to activate Tgr5 in the adipose tissues.The metabolic benefits of Ftl were abolished in Cyp27 al^(-/-) mice which have much lower BA levels.These results identify Ftl as a single compound with opposite activities on two key BA receptors to alleviate high fat diet-induced obesity and insulin resistance in mice.Lili Ding Qiaoling Yang Eryun Zhang Yangmeng Wang Siming Sun Yingbo Yang Tong Tian Zhengcai Ju Linshan Jiang Xunjiang Wang Zhengtao Wang Wendong Huang Li Yang 2021Acta Pharmaceutica Sinica B2021,11,6:10
2Bile acid signaling and bariatric surgery显示文摘The rapid worldwide rise in obesity rates over the past few decades imposes an urgent need to develop effective strategies for treating obesity and associated metabolic complications.Bariatric surgical procedures,such as Roux-en-Y gastric bypass(RYGB)and vertical sleeve gastrectomy(VSG),currently provide the most effective treatment for obesity and type 2 diabetes(T2D),as well as for non-alcoholic steatohepatitis(NASH).However,the underlying mechanisms of the beneficial effects of bariatric surgery remain elusive.Recent studies have identified bile acids as potential signaling molecules involved in the beneficial effects of bariatric surgery.This review focuses on the most recent studies on the roles of bile acids and bile acid receptors Farnesoid X receptor(FXR)and G protein-coupled bile acid receptor 5(TGR5)in bariatric surgery.We also discuss the possibility of modulating bile acid signaling as a pharmacological therapeutic approach to treating obesity and its associated metabolic complications.Jingyan Tian Silvia Huang Siming Sun Lili Ding Eryun Zhang Yanjun Liu Wendong Huang 2017Liver Research2017,1,4:2
