Obesity and its complications constitute a substantial burden. Considerable published research describes the novel relationships between obesity gut microbiota communities. It is becoming evident that behave in pivotal role their ability to influence homeostatic mechanisms either benefit or detriment of host health, extent which not fully understood. A greater understanding contribution towards pathophysiology revealing new therapeutic avenues tackle global epidemic. This review focuses on causal associations with obesity, proposed central encouraging development promising prospective methods for manipulation.

Accumulating evidence indicates gut microbiota contributes to aging-related disorders. However, the exact mechanism underlying dysbiosis-related pathophysiological changes during aging remains largely unclear. In current study, we first performed remodeling on old mice by fecal transplantation (FMT) from young mice, and then characterized bacteria signature that was specifically altered FMT. Our results revealed FMT significantly improved natural systemic disorders, particularly exerted hepatoprotective effects, glucose sensitivity, hepatosplenomegaly, inflammaging, antioxidative capacity intestinal barrier. Moreover, increased abundance of A.muciniphila, which almost nondetectable in mice. Interestingly, A.muciniphila supplementation also similar benefits with Notably, targeted metabolomics short chain fatty acids (SCFAs) only acetic acid consistently reversed Then, intervention beneficial actions both Caenorhabditis elegans conclusion, our study demonstrated disorders through its derived acid, suggesting interventions potent stimulative A. muciniphila growth production alternative effective way maintain healthy aging.

Abstract Background and Aims Bile acids are hepatic metabolites have many properties considered to be relevant the pathophysiology of NAFLD. Circulating levels intestinal microbiome‐modified bile acid deoxycholate increased in cirrhosis. Approach Results To further elucidate role microbiota linked progressively severe NAFLD, a multiomic study feces including 16S rRNA sequencing, microbial transcriptomics metabolomics was performed cohort with varying phenotypes Several origin derived from deoxycholic (DCA) (glycodeoxycholate, 7‐ketodeoxycholic acid, dehydrocholic acid) disease activity fibrosis stage. These were expression salt hydrolase, operon (BaiCD) hydroxysteroid dehydrogenases (hdhA) required for DCA downstream metabolite synthesis providing mechanistic basis altered profiles progression.

Background Probiotics play a vital role in treating immune and inflammatory diseases by improving intestinal barrier function; however, comprehensive evaluation is missing. The present study aimed to explore the impact of probiotics on related function, inflammation, microbiota composition. A systematic review meta-analyses were conducted. Methods Four major databases (PubMed, Science Citation Index Expanded, CENTRAL, Embase) thoroughly searched. Weighted mean differences calculated for continuous outcomes with corresponding 95% confidence intervals (CIs), heterogeneity among studies was evaluated utilizing I2 statistic (Chi-Square test), data pooled using random effects meta-analyses. Results Meta-analysis from total 26 RCTs (n = 1891) indicated that significantly improved gut function measured levels TER (MD, 5.27, CI, 3.82 6.72, P < 0.00001), serum zonulin (SMD, -1.58, -2.49 -0.66, 0.0007), endotoxin -3.20, -5.41 -0.98, 0.005), LPS -0.47, -0.85 -0.09, 0.02). Furthermore, probiotic groups demonstrated better efficacy over control reducing factors, including CRP, TNF-α, IL-6. can also modulate structure boosting enrichment Bifidobacterium Lactobacillus.

Recent studies have indicated that gut microbiota-mediated oxidative stress is significantly associated with intestinal diseases such as colorectal cancer, ulcerative colitis, and Crohn’s disease. The level of reactive oxygen species (ROS) has been reported to increase when the microbiota dysregulated, especially several bacterial metabolites are present. Although healthy plays a vital role in defending against excessive stress, disease influenced by ROS, this process controlled immunological responses, DNA damage, inflammation. In review, we discuss relationship between from an perspective. addition, also provide summary most recent therapeutic approaches for preventing or treating modifying microbiota.

Arsenic has been ranked as the most hazardous substance by U.S. Agency for Toxic Substances and Disease Registry. Environmental arsenic exposure-evoked health risks have become a vital public concern worldwide owing to widespread existence of arsenic. Multi-omics is revolutionary technique data analysis providing an integrated view bioinformation comprehensively systematically understanding elaborate mechanism diseases. This study aimed at uncovering potential contribution liver-microbiota-gut axis in chronic inorganic exposure-triggered biotoxicity chickens based on multi-omics technologies. Forty Hy-Line W-80 laying hens were chronically exposed sodium arsenite with dose-dependent manner (administered drinking water containing 10, 20, or 30 mg/L arsenic, respectively) 42 d, followed transcriptomics, serum non-targeted metabolome, 16S ribosomal RNA gene sequencing accordingly. intervention induced serious chicken liver dysfunction, especially severe fibrosis, simultaneously altered ileal microbiota populations, impaired intestinal barrier, further drove enterogenous lipopolysaccharides translocation via portal vein circulation aggravating damage. Furtherly, injured disturbed bile acids (BAs) homoeostasis through strongly up-regulating BAs synthesis key rate-limiting enzyme CYP7A1, inducing excessive total accumulation, accompanied massive primary BA—chenodeoxycholic acid. Moreover, concentrations secondary BAs—ursodeoxycholic acid lithocholic markedly repressed, which might involve repressed dehydroxylation Ruminococcaceae Lachnospiraceae families. Abnormal metabolism turn promoted injury, ultimately perpetuating pernicious circle chickens. Notably, obvious depletion abundance four profitable microbiota, Christensenellaceae, Ruminococcaceae, Muribaculaceae, Faecalibacterium, correlated tightly this hepato-intestinal process Our demonstrates that exposure evokes disruption establishes scientific basis evaluating risk environmental pollutant
