Voluntary wheel running ameliorated the deleterious effects of high-fat diet on glucose metabolism,gut microbiota and microbial-associated metabolites

Exercise training is critical for the early prevention and treatment of obesity and diabetes mellitus.However,the mechanism with gut microbiota and fecal metabolites underlying the effects of voluntary wheel running on high-fat diet induced abnormal glucose metabolism has not been fully elaborated.C57BL/6 male mice were randomly assigned to 4 groups according to diets(fed with normal chow diet or high-fat diet)and running paradigm(housed in static cage or with voluntary running wheel).An integrative 16S rDNA sequencing and metabolites profiling was synchronously performed to characterize the effects of voluntary wheel running on gut microbiota and metabolites.It showed that voluntary wheel running prevented the detrimental effects of high-fat feeding on glucose metabolism 16S rDNA sequencing showed remarkable changes in Rikenella and Marvinbryantia genera.Metabolic profiling indicated multiple altered metabolites,which were enriched in secondary bile acid biosynthesis signaling.In conclusion,our study indicated that voluntary wheel running significantly improved glucose metabolism and counteracted the deleterious effects of high-fat feeding on body weight and glucose intolerance.We further found that voluntary wheel running could integratively program gut microbiota composition and fecal metabolites changes,and may regulate muricholic acid metabolism and secondary bile acid biosynthesis in high-fat fed mice.

Effects of forsythin extract in Forsythia leaves on intestinal microbiota and short-chain fatty acids in rats fed a high-fat diet

Forsythia suspensa,belonging to the deciduous shrubs of the Luteaceae family,a traditional Chinese medicine,has effects of alleviating swelling,clearing heat,detoxification and promoting blood circulation.The leaves of F.suspensa contain multiple chemical components and have a long history of use in folk medicines and health foods.The purpose of this study was to explore the effects of forsythin extract from F.suspensa leaves on intestinal microbiota and short-chain fatty acid(SCFA)content in rats with obesity induced by a high-fat diet.Forsythin extract in F.suspensa leaves increased the abundance of the intestinal microbiota,ameliorated intestinal microbiota disorders and inhibited the increase in total SCFA content in the intestinal tract in rats with obesity induced by a high-fat diet.These results suggested that forsythin extract in F.suspensa leaves may slow the development of obesity induced by a high-fat diet;thus,its active components and efficacy are worthy of further study.

Therapeutic effects of Lingguizhugan decoction in a rat model of high-fat diet-induced insulin resistance

BACKGROUND Lingguizhugan(LGZG)decoction is a widely used classic Chinese medicine formula that was recently shown to improve high-fat diet(HFD)-induced insulin resistance(IR)in animal studies.AIM To assess the therapeutic effect of LGZG decoction on HFD-induced IR and explore the potential underlying mechanism.METHODS To establish an IR rat model,a 12-wk HFD was administered,followed by a 4-wk treatment with LGZG.The determination of IR status was achieved through the use of biochemical tests and oral glucose tolerance tests.Using a targeted metabolomics platform to analyze changes in serum metabolites,quantitative real-time PCR(qRT-PCR)was used to assess the gene expression of the ribosomal protein S6 kinase beta 1(S6K1).RESULTS In IR rats,LGZG decreased body weight and indices of hepatic steatosis.It effectively controlled blood glucose and food intake while protecting islet cells.Metabolite analysis revealed significant differences between the HFD and HFDLGZG groups.LGZG intervention reduced branched-chain amino acid levels.Levels of IR-related metabolites such as tryptophan,alanine,taurine,and asparagine decreased significantly.IR may be linked to amino acids due to the contemporaneous increase in S6K1 expression,as shown by qRT-PCR.CONCLUSIONS Our study strongly suggests that LGZG decoction reduces HFD-induced IR.LGZG may activate S6K1 via metabolic pathways.These findings lay the groundwork for the potential of LGZG as an IR treatment.

Time-dependent impact of a high-fat diet on the intestinal barrier of male mice

BACKGROUND Excessive saturated fat intake compromises the integrity of the intestinal mucosa,leading to low-grade inflammation,impaired mucosal integrity,and increased intestinal permeability,resulting in the migration of lipopolysaccharide(LPS)to other tissues.AIM To evaluate the chronic effects(at 10 and 16 wk)of a high-fat diet(HFD)(with 50%energy as fat)on the phylogenetic gut microbiota distribution and intestinal barrier structure and protection in C57BL/6 mice.METHODS Forty adult male mice were divided into four nutritional groups,where the letters refer to the type of diet(control and HFD or HF)and the numbers refer to the period(in weeks)of diet administration:Control diet for 10 wk,HFD for 10 wk,control diet for 16 wk,and HFD for 16 wk.After sacrifice,biochemical,molecular,and stereological analyses were performed.RESULTS The HF groups were overweight,had gut dysbiosis,had a progressive decrease in occludin immunostaining,and had increased LPS concentrations.Dietary progression reduced the number of goblet cells per large intestine area and Mucin2 expression in the HF16 group,consistent with a completely disarranged intestinal ultrastructure after 16 wk of HFD intake.CONCLUSION Chronic HFD intake causes overweight,gut dysbiosis,and morphological and functional alterations of the intestinal barrier after 10 or 16 wk.Time-dependent reductions in goblet cell numerical density and mucus production have emerged as targets for countering obesity-driven intestinal damage.

High-fat diet and oral infection induced type 2 diabetes and obesity development under different genetic backgrounds

Background:Type 2 diabetes(T2D)is an adult-onset and obese form of diabetes caused by an interplay between genetic,epigenetic,and environmental components.Here,we have assessed a cohort of 11 genetically different collaborative cross(CC)mouse lines comprised of both sexes for T2D and obesity developments in response to oral infection and high-fat diet(HFD)challenges.Methods:Mice were fed with either the HFD or the standard chow diet(control group)for 12 weeks starting at the age of 8 weeks.At week 5 of the experiment,half of the mice of each diet group were infected with Porphyromonas gingivalis and Fusobacterium nucleatum bacteria strains.Throughout the 12-week experimental period,body weight(BW)was recorded biweekly,and intraperitoneal glucose tolerance tests were performed at weeks 6 and 12 of the experiment to evaluate the glucose tolerance status of mice.Results:Statistical analysis has shown the significance of phenotypic variations between the CC lines,which have different genetic backgrounds and sex effects in different experimental groups.The heritability of the studied phenotypes was estimated and ranged between 0.45 and 0.85.We applied machine learning methods to make an early call for T2D and its prognosis.The results showed that classification with random forest could reach the highest accuracy classification(ACC=0.91)when all the attributes were used.Conclusion:Using sex,diet,infection status,initial BW,and area under the curve(AUC)at week 6,we could classify the final phenotypes/outcomes at the end stage of the experiment(at 12 weeks).

Production of Corn (Zea mays) Starch and Cassava (Manihot esculenta) Starch and Their Application as Yogurt Stabilizer

The present study evaluated the stabilizing effect of starch produced from corns and cassava on the stability of cow milk yogurt. A sample of both corn and cassava starch was selected and used in the yogurt making as stabilizers. The yogurt samples have been analyzed for their WHC, syneresis and protein content. The yogurt with no added starch has found to have very low WHC and high syneresis compared to other samples. The yogurt made with the addition of corn starch as a stabilizer was highly accepted than the yogurt with cassava starch and the yogurt without starch. The findings from this study provide an alternative to add the value of local corns and cassava.

Physicochemical,rheological and antioxidant profiling of yogurt prepared from non-enzymatically and enzymatically hydrolyzed potato powder under refrigeration

Evidences show that the storage period greatly affects the quality of yogurt.In this study,three types of yogurt:control yogurt(CY),non-hydrolyzed potato powder yogurt(PPY)and enzymatically hydrolyzed potato powder yogurt(EHPPY)were prepared at 42℃ for 5 h and stored for 28 days at 4℃.The yogurts were evaluated for quality characteristics at different storage periods.Negligible differences in pH values,titratable acidities and viable counts were detected in all three types of yogurt during storage.However,compared to other yogurts,EHPPY exhibited desirable water holding capacity,throughout the storage period.Apart from this,sensory properties and antioxidant activities(2-diphenyl-1-picryl-hydrazyl(DPPH)free radical scavenging activity and ferric reducing antioxidant power(FRAP))of EHPPY were also significantly improved during the storage period.Furthermore,the storage(G’)and loss(G”)modulus of PPY,EHPPY were lower than CY at 4℃ while a hysteresis loop was shown by all yogurts at the temperature range of 4-50℃ indicating higher G’(elasticity)than G”(viscosity).Based on our findings,EHPP could be an important functional ingredient in improving the quality and storage stability of yogurt for its production at an industrial level.

SESN2 ablation weakens exercise benefits on resilience of gut microbiota following high-fat diet consumption in mice

Gut dysbiosis is associated with several pathological processes.Previous study showed that regular exercise can protect against dysmetabolism in high-fat diet(HFD)fed mice through butyrate-SESN2 pathway,and SESN2 ablation weakened the protective effects of exercise.Here,we investigated whether SESN2-defi ciency suppresses the exercise response to microbiota composition and subsequently reduces the benefi ts of exercise on dysmetabolism induced by HFD.Wild type(WT)and SESN2^(-/-)mice were assigned to fi ve-groups,fed with either normal chow or HFD and with or without exercise training for 15-week.Fecal microbiota composition and function were assessed by 16S rRNA sequencing.The sequencing results showed that SESN2^(-/-)mice displayed differed microbiome profile from WT mice.Exercise enriched the microflora diversity and increased the benefi cial microbial species in WT mice,and SESN2 ablation weakened the benefi cial effects of exercise on microbial resilience following HFD consumption.Moreover,network analysis revealed that exercise increased correlation density and clustering of operational taxonomic units in WT mice only.KEGG demonstrated that some dominant metabolism-related enzymes and modules increased in SESN2^(-/-)mice.Our results indicated that the effects of exercise on metabolism are associated with the perturbations of gut microbiota composition and function,suggesting that SESN2 contributes to maintain metabolic homeostasis.

The prevention of high-fat diet-induced non-alcoholic fatty liver disease in mice by Fucoidan

Objective:To study the preventive effect of fucoidan on non-alcoholic fatty liver disease induced by high fat diet.Methods:The experimental mice were randomly divided into three groups:control group,high-fat diet group and fucoidan intervention group.The control group was fed a standard diet,and the other two groups were fed a high-fat diet.The control group and the high-fat diet group were given normal saline intragastric administration every day,and the intervention group was given intragastric administration of fucoidan polysaccharide solution at a dose of 100 mg∙kg^(-1)∙d^(-1) once a day for continuous intervention for 12 weeks.After the last intragastric administration for 12 h,the body weight and liver weight of each group of mice were measured,and the liver index was calculated.The contents of alanine aminotransferase(ALT),aspartate aminotransferase(AST),total cholesterol(TC)and triglyceride(TG)in liver tissues of mice in each group were detected by biochemical kit.Hematoxylin-eosin staining(HE)was used to compare the pathological morphological changes of liver tissue in each group.The contents of inflammatory factor interleukin-6(IL-6),tumor necrosis factor(TNF-α)and oxidative stress index malondialdehyde(MDA),and the activities of glutathione peroxidase(GSH-Px)and superoxide dismutase(SOD)in liver tissues of mice in each group were determined.Results:Compared with the control group,the body weight and liver index of mice receiving high fat diet increased significantly(P<0.01).In addition,the contents of TG,TC,AST and ALT in liver tissue of high-fat diet group were significantly increased compared with that of control group(P<0.01).The liver tissue of mice in the high-fat diet group also showed significant pathological changes,accompanied by increased expression of inflammatory factors and a significant increase in oxidative stress response.However,compared with the mice in the high-fat diet group,the above indexes were significantly improved in the liver tissue of the mice treated with fucoidan(P<0.01).Conclusion:Fucoidan can inhibit liver lipid deposition,liver inflammation and oxidative stress induced by high fat diet.

Endoplasmic Reticulum Stress-induced Endothelial Dysfunction Promotes Neointima Formation after Arteriovenous Grafts in Mice on High-fat Diet

Objective Endothelial dysfunction is one candidate for triggering neointima formation after arteriovenous grafts(AVGs),but the factors mediating this process are unclear.The purpose of this study was to investigate the role of endoplasmic reticulum stress(ERS)-induced endothelial dysfunction in neointima formation following AVGs in high-fat diet(HFD)mice.Methods CCAAT-enhancer-binding protein-homologous protein(CHOP)knockout(KO)mice were created.Mice were fed with HFD to produce HFD model.AVGs model were applied in the groups of WT ND,WT HFD,and CHOP KO HFD.Human umbilical vein endothelial cells(HUVECs)were cultured with oxidized low density lipoprotein(ox-LDL)(40 mg/L)for the indicated time lengths(0,6,12,24 h).ERS inhibitor tauroursodeoxycholic acid(TUDCA)was used to block ERS.Immunohistochemical staining was used to observe the changes of ICAM1.Changes of ERS were detected by real-time RT-PCR.Protein expression levels and ERS activation were detected by Western blotting.Endothellial cell function was determined by endothelial permeability assay and transendothelial migration assay.Results HFD increased neointima formation in AVGs associated with endothelial dysfunction.At the same time,ERS was increased in endothelial cells(ECs)after AVGs in mice consuming the HFD.In vitro,ox-LDL was found to stimulate ERS,increase the permeability of the EC monolayer,and cause endothelial dysfunction.Blocking ERS with TUDCA or CHOP siRNA reversed the EC dysfunction caused by ox-LDL.In vivo,knockout of CHOP(CHOP KO)protected the function of ECs and decreased neointima formation after AVGs in HFD mice.Conclusion Inhibiting ERS in ECs could improve the function of AVGs.

Targeted microbiome metabolomics reveals flaxseed oil supplementation regulated the gut microbiota and farnesoid X receptor pathway in high-fat diet mice

Flaxseed oil(FSO)rich in n-3 polyunsaturated fatty acids(PUFAs)can protect against obesity and insulin resistance,but the underlying mechanism is unknown.An integrative multiomics of the microbiome and targeted metab olomics approach was performed to investigate the possible pathway for flaxseed oil supplementation on reducing serum total cholesterol,triglyceride and epididymal adipose in high-fat diet mice.FSO ameliorated the gut microbial dysbiosis by increasing the community diversity and the abundance of Clostridiales and Ruminococcaceae.These effects were associated with the regulation of bile acid(BAs)in the feces.FSO reduced the concentrations of conjugated BAs,such as cholic acid,tauro-α-murocholic acid,and tauro-ursodesoxycholic acid in feces,which in turn inhibit the intestinal farnesoid X receptor(FXR)-fibroblast growth factor(FGF)15 signaling pathway.Further analysis revealed that FSO activated FXR in the liver and regulated downstream gene expression(SHP,SREBP-1c,and CPT-1a),which promoted lipolysis and inhibited lipogenesis.The results of this study suggest that FSO modulates serum lipid concentrations by regulating the gut microbiota,FXR-FGF15 signaling and BA metabolism.

Effects of Polygonatum sibiricum Polysaccharide (PSP) on Inflammatory Factors in Rats Fed on High-fat Diet

[Objectives]This study was conducted to explore the effects of Polygonatum sibiricum polysaccharide(PSP)on chronic intestinal inflammation caused by high-fat diet.[Methods]Thirty five male healthy SD rats were randomly divided into a normal control group(NC,normal diet,n=10)and a high-fat diet group(HF,high-fat diet,n=25).After 8 weeks,an obesity model was established.The HF group was randomly divided into an HF group and a PSP treatment group[PSP,300 mg/(kg·d)].After 6 weeks of intervention with PSP,rat serum was collected,and the spleen and thymus were stripped,and weighed.Serum IgG,IgM,LPS and IL-1βand IL-6 contents were detected by ELISA,and HE staining was adopted to observe the pathological changes of the colon tissue.[Results]PSP reduced the level of LPS caused by high-fat diet and the levels of inflammatory factors IL-6 and TNF-α,increased the indexes of the thymus and spleen serving as immune organs,increased IgG and IgM contents,and alleviated pathological damage to the colon tissue caused by high-fat diet.[Conclusions]This study provides a theoretical basis and experimental basis for the development of drugs for treating metabolic diseases such as obesity and inflammation.

Effects of Polygonatum sibiricum Polysaccharide on Antioxidant Capacity of the Liver in High-fat Diet Rats

[Objectives]This study was conducted to investigate the effects of Polygonatum sibiricum polysaccharide(PSP)on antioxidant function in high-fat diet obese rats.[Methods]Thirty five healthy male SD rats were selected to establish an obesity model after feeding a high-fat for 8 weeks.They were then randomly divided into a normal group(NC),a high-fat diet group(HF),and an HF+P.sibiricum polysaccharide group[HF+PSP,300 mg/(kg·d)].After 6 weeks of PSP intervention,the serum and liver of rats were collected,and the activity of aspartate transaminase(AST)and alanine aminotransferase(ALT)in serum,the enzyme activity of superoxide dismutase(SOD),catalase(CAT)and glutathione peroxidase(GSH-Px)and malondialdehyde(MDA)in liver tissue were measured.The pathological changes of liver tissue were observed by HE staining.[Results]Compared with the HF group,PSP could effectively inhibit obesity caused by high-fat diet.It reduced body weight and serum AST and ALT levels,increased the contents of T-SOD,CAT and GSH-Px in the liver,and inhibited the accumulation of MDA content,thereby reducing damage to liver cells caused by a high-fat diet.It indicated that PSP could effectively inhibit obesity in high-fat diet rats and enhance their antioxidant capacity.[Conclusions]This study provides a reference for the study of the antioxidant capacity of PSP.
