Short-chain fatty acids are important nutrients that regulate milk fat synthesis.They regulate milk syn-thesis via the sterol regulatory element binding protein 1(SREBP1)pathway;however,the details are still unknown.Here,the regulation and mechanism of sodium acetate(SA)in milk fat synthesis in bovine mammary epithelial cells(BMECs)were assessed.BMECs were treated with SA supplementation(SAþ)or without SA supplementation(SA-),and milk fat synthesis and activation of the SREBP1 pathway were increased(P=0.0045;P=0.0042)by SAþand decreased(P=0.0068;P=0.0031)by SA-,respectively.Overexpression or inhibition of SREBP1 demonstrated that SA promoted milk fat synthesis(P=0.0045)via the SREBP1 pathway.Overexpression or inhibition of TATA element modulatory factor 1(TMF1)demon-strated that TMF1 suppressed activation of the SREBP1 pathway(P=0.0001)and milk fat synthesis(P=0.0022)activated by SAþ.Overexpression or inhibition of TMF1 and SREBP1 showed that TMF1 suppressed milk fat synthesis(P=0.0073)through the SREBP1 pathway.Coimmunoprecipitation analysis revealed that TMF1 interacted with SREBP1 in the cytoplasm and suppressed the nuclear localization of SREBP1(P=0.0066).The absence or presence of SA demonstrated that SA inhibited the expression of TMF1(P=0.0002)and the interaction between TMF1 and SREBP1(P=0.0001).Collectively,our research sug-gested that TMF1 was a new negative regulator of milk fat synthesis.In BMECs,SA promoted the SREBP1 pathway and milk fat synthesis by suppressing TMF1.This study enhances the current understanding of the regulation of milk fat synthesis and provides new scientific data for the regulation of milk fat synthesis. 展开更多

Isabel grape(IG)products have high contents of phenolic compounds and fiber recognized for their positive impacts on microorganisms associated with health benefits to host.This study evaluated the effects of goat yogurts formulated with ingredients from IG integral valorization on the growth and metabolism of different probiotic strains,as well as on the population of selected bacterial groups and metabolic activity of human colonic microbiota in vitro.Goat yogurts with IG ingredients(IGI)stimulated the growth of tested Lactobacillus and Bifidobacterium probiotic strains during a 48-h cultivation,as well as decreased the pH values and enhanced the organic acid production.Goat yogurts with IGI increased the population of Lactobacillus spp.and Bifidobacterium spp.during a 24-h in vitro colonic fermentation.A stable Firmicutes:Bacteroidetes ratio close to 1 was found in media with goat yogurt formulations during the colonic fermentation,being similar to the effect caused by fructooligosaccharides.Goat yogurt formulations with IGI caused increased production of short-chain fatty acids and sugar consumption during colonic fermentation.Goat yogurts with IGI should be a valuable strategy for development of novel added-value foods with beneficial effects on gut microbiota and human health. 展开更多

Pancreatic cancer(PC)is one of the most common causes of cancer-associated death worldwide,with a low rate of 5-year survival.Currently,the pathogenesis of PC is complicated,with no efficient therapy.Coronavirus disease 2019(COVID-19)disease caused by severe acute respiratory syndrome coronavirus 2 further exacerbates the challenge of patients with PC.The alteration of gut microbiota caused by COVID-19 infection may impact PC progression in patients via immune regulation.The expression of inflammatory immune mediators such as interleukin(IL)-6,IL-8,and IL-10 has been found to increase in both PC and COVID-19 patients,which is associated with the disease severity and prognostic outcome.Gut microbiome serves as a critical connector between viral infection and PC.It can regulate host systemic immune response and impact the efficacy of immunotherapy.Here,we first demonstrated the features of inflammatory cytokines in both diseases and their impact on disease outcomes.Then,we demonstrated the importance of immunotherapeutic strategies.This includes the immune modulation that targets a single or dual receptors using a single agent or their combinations for the treatment of PC in patients who get infected with COVID-19.Additionally,we explored the possibility of managing the disease by regulating gut microbiome.Overall,modulation of the lung-gut-pancreases axis can boost anti-cancer immunotherapy and reduce adverse prognostic outcomes. 展开更多

The emergence and rapid spread of antimicrobial resistance is of global public health concern.The gut microbiota harboring diverse commensal and opportunistic bacteria that can acquire resistance via horizontal and vertical gene transfers is considered an important reservoir and sink of antibiotic resistance genes(ARGs).In this review,we describe the reservoirs of gut ARGs and their dynamics in both animals and humans,use the One Health perspective to track the transmission of ARG-containing bacteria between humans,animals,and the environment,and assess the impact of antimicrobial resistance on human health and socioeconomic development.The gut resistome can evolve in an environment subject to various selective pressures,including antibiotic administration and environmental and lifestyle factors(e.g.,diet,age,gender,and living conditions),and interventions through probiotics.Strategies to reduce the abundance of clinically relevant antibiotic-resistant bacteria and their resistance determinants in various environmental niches are needed to ensure the mitigation of acquired antibiotic resistance.With the help of effective measures taken at the national,local,personal,and intestinal management,it will also result in preventing or minimizing the spread of infectious diseases.This review aims to improve our understanding of the correlations between intestinal microbiota and antimicrobial resistance and provide a basis for the development of management strategies to mitigate the antimicrobial resistance crisis. 展开更多

Objectives:The goal of this study was to evaluate the modulatory effect of chitosan oligosaccharide-nisin conjugate(CON-C)on intestinal microbiota of human flora-associated(HFA)mice and also reveal its effect towards the high-fat diet(HFD)-induced obesity.Both Chitosan oligosaccharides and nisin showed great potential in modulating the intestinal microbiota,so it is worth to explore whether the modulation effect of chitosan oligosaccharide could be improved by covalently binding with nisin.Materials and Methods:CON-C was prepared by heating the mixed solution of chitosan oligosaccharide and nisin at 80℃ and pH 2.0 for 24h.The structure of CON-C were analyzed by Fourier transform-infrared spectroscopy(FT-IR)and X-ray diffraction(XRD).The CON-C’s anti-obesity effect and modulatory effect toward intestinal microbiota were analyzed using human flora-associated(HFA)mice model.Results:CON-C could alleviated HFD-induced gut dysbiosis,by significantly decreasing the numbers of Bifidobacterium and Lactobacillus/Enterococcus spp.,and increasing the numbers of Bacteroides-Prevotella and Clostridium groups.CON-C could also enriched the most differentially expressed genes through KEGG pathways of biosynthesis of amino acids,two-component system,and ATP binding cassette(ABC)transporters.Conclusions:The improved therapeutic effect of CON-C against HFD-induced obesity has been approved,and hence,CON-C has a great potential to be utilized as a functional food ingredient in reducing body weight. 展开更多
