| 1 | Network pharmacology analysis to explore mechanism of Three Flower Tea against nonalcoholic fatty liver disease with experimental support using high-fat diet-induced rats显示文摘Objective:Nonalcoholic fatty liver disease(NAFLD)has become a common chronic liver disease that is harmful to human health.Moreover,there is currently no FDA-approved first-line drug for the treatment of nonalcoholic steatohepatitis(NASH)or NAFLD.Traditional Chinese medicine(TCM)is widely used to ameliorate liver diseases,such as the traditional ancient recipe called Three Flower Tea(TFT),which consists of double rose(Rosa rugosa),white chrysanthemum(Chrysanthemum morifolium),and Daidaihua(Citrus aurantium).However,the mechanisms of the action of TFT are not clear.Therefore,this study aimed to elucidate the mechanisms of TFT against NAFLD in high-fat diet(HFD)-induced rats.Methods:This study utilized bioinformatics and network pharmacology to establish the active and potential ingredient-target networks of TFT.Furthermore,a protein–protein interaction(PPI)network was constructed,and enrichment analysis was performed to determine the key targets of TFT against NAFLD.Furthermore,an animal experiment was conducted to evaluate the therapeutic effect and confirm the key targets of TFT against NAFLD.Results:A total of 576 NAFLD-related genes were searched in Gene Cards,and under the screening criteria of oral bioavailability(OB)≥30%and drug-likeness(DL)≥0.18,a total of 19 active ingredients and 210 targets were identified in TFT.Network pharmacology analysis suggested that 55 matching targets in PPIs were closely associated with roles for NAFLD treatment.Through the evaluation of network topology parameters,four key central genes,PPARγ,SREBP,AKT,and RELA,were identified.Furthermore,animal experiments indicated that TFT could reduce plasma lipid profiles,hepatic lipid profiles and hepatic fat accumulation,improve liver function,suppress inflammatory factors,and reduce oxidative stress.Through immunoblotting and immunofluorescence analysis,PPARγ,SREBP,AKT,and RELA were confirmed as targets of TFT in HFD-induced rats.Conclusion:In summary,our results indicate that TFT can prevent and treat NAFLD via multiple targets,including lipid accumulation,antioxidation,insulin sensitivity,and inflammation. | Peixuan Wu Shufei Liang Yanping He Rui Lv Bendong Yang Meng Wang Chao Wang Yong Li Xinhua Song Wenlong Sun | 2022 | Chinese Herbal Medicines2022，14，2： | 2 |
| 4 | Identification,Characterization,and Probiotic Potentials of Lactobacillus pentosus SF-1显示文摘In recent years probiotics have been considered as a potential substitution of antibiotics to control pathogens and treat infectious diseases in aquaculture.In the present study a strain of Lactobacillus pentosus,named as L.pentosus SF-1,was isolated from waters in aquaculture.The species identification of this strain was conducted by 16S rRNA sequence,and the physiological and biochemical characteristics of this strain were assessed.Furthermore,the virulence,antibiotic sensitivity,cell surface characteristics and acid/base-resistance of L.pentosus SF-1 were determined to evaluate the probiotic potentials of this strain.Specifically,L.pentosus SF-1 is sensitive to most common antibiotics,and no hemolysin was generated from it,indicating the safety of this strain to hosts.In addition,L.pentosus SF-1 was able to tolerate the artificial gastric juice at pH 3 for 4 h and the artificial intestinal fluid at pH 6.8 or 8.0 for 6 h.Moreover,the analysis of self-aggregation and the adhesion of L.pentosus SF-1 to organic solvents suggested a high potential of L.pentosus SF-1 to inhabit the hosts,which was confirmed by testing the colonization of L.pentosus SF-1 in germ-free zebrafish.Interestingly,L.pentosus SF-1 displayed a high bactericidal activity against several bacterial pathogens.Consistently,the incubation of L.pentosus SF-1 significantly promoted the expression of antimicrobial components in zebrafish,contributing to the protection of the fish from E.tarda infection in vivo.Taken together,the probiotic strain L.pentosus SF-1 could be applied as anti-infection reagent in aquaculture. | JIAO Lin LIANG Shufei CHU Ruixia WANG Wentao MAI Kangsen LIU Ming WAN Min | 2024 | Journal of Ocean University of China2024，23，2： | 0 |
