mWGS analysis of the fecal microbiota of WT and TCRb-/- mice

(Submitter supplied) The gut microbiota plays an important role in host health. Microbiota dysbiosis has been implicated in the global epidemic of Metabolic Syndrome (MetS) and could impair host metabolism by noxious metabolites. It has been well established that the gut microbiota is shaped by host immune factors. However, the effect of T cells on the gut microbiota is yet unknown. Here, we performed a metagenomic whole-genome shotgun sequencing (mWGS) study of the microbiota of TCRb-/- mice, which lack alpha/beta T cells.

Fecal microbiota transplantation from female donors restores gut permeability and reduces liver injury and inflammation in middle-aged male mice exposed to alcohol

(Submitter supplied) Background: Alcohol misuse, binge drinking pattern, and gender-specific effects in the middle-aged population has been clearly underestimated. In the present study, we focused on understanding gender-specific effects of alcohol exposure on the gut-liver axis and the role of gut microbiota in modulating gender-specific responses to alcohol consumption. Methods: Fifty-two-week-old female and male C57BL/6 mice were fasted for 12 h, and then administered a single oral dose of ethanol (EtOH) (6 g/kg). more...

Unveiling microbial dynamics in lung adenocarcinoma and adjacent nontumor tissues: Insights from nicotine exposure and diverse clinical stages via Nanopore Sequencing Technology

(Submitter supplied) Background: Lung is the largest mucosal area of the human body and directly connected to the external environment, facing microbial exposure and environmental stimuli. Therefore, studying the internal microorganisms of the lung is crucial for a deeper understanding of the relationship between microorganisms and the occurrence and progression of lung cancer. Methods: Tumor and adjacent nontumor tissues were collected from 38 lung adenocarcinoma patients and used nanopore sequencing technology to sequence the 16s full-length sequence of bacteria, and combining bioinformatics methods to identify and quantitatively analyze microorganisms in tissues, as well as to enrich the metabolic pathways of microorganisms. more...

Role of folic acid in regulating intestinal flora and short-chain fatty acids based on in vitro fermentation model

(Submitter supplied) Folic acid deficiency is common worldwide and is linked to intestinal flora imbalance. The intestinal microbial utilization of folic acid based on model animals faces the challenges of repeatability and individual variability. In this study, we built an in vitro fecal slurry culture model deficient in folic acid. We examined the effects of supplementation with different forms of folic acid (5-methyltetrahydrofolate and non-reduced folic acid) on the modulation of intestinal flora. more...

Metagenomic sequencing of adult zebrafish feces after SMZ exposure (Exposure of Danio rerio to environmental sulfamethoxazole may contribute to neurobehavioral abnormalities via gut microbiome disturbance)

(Submitter supplied) The neurotoxic effects and mechanisms of low-dose and long-term sulfamethoxazole (SMZ) exposure remain unknown. This study exposed zebrafish to environmental SMZ concentrations and observed behavioral outcomes. SMZ exposure increased hyperactivity and altered the transcript levels of 17 genes associated with neurological function. It impaired intestinal function by reducing the number of intestinal goblet cells and lipid content. more...

Prebiotic proanthocyanidins inhibit bile reflux-induced esophageal adenocarcinoma through reshaping the gut microbiome

(Submitter supplied) The gut and local esophageal microbiome progressively shift from healthy commensal bacteria to inflammatory-linked pathogenic bacteria in patients with gastroesophageal reflux disease, Barrett’s esophagus and esophageal adenocarcinoma (EAC). However, mechanisms by which microbial communities contribute to reflux-driven EAC remain incompletely understood and challenging to target. Herein, we utilized a rat reflux-induced EAC model to investigate targeting the gut microbiome-esophageal metabolome axis with cranberry proanthocyanidins (C-PAC) to inhibit EAC progression. more...

The effects of periodic restricted feeding on Rhesus Macaques

(Submitter supplied) Dietary restriction has shown benefits in physiological, metabolic, and molecular signatures associated with aging. In mice, periodic dietary restriction, that accompanies cyclical periods of reduced calories, mitigates aging phenotypes, yet the effects of this periodic restriction in higher order, genetically heterogenous mammals, have not been investigated. Reducing caloric intake in middle-aged Rhesus Macaques for four days followed by ad libitum eating for ten days, repeated for six cycles, led to significant changes in body composition, metabolome, and microbiome of the restricted monkeys compared to their ad libitum fed (age and sex matched) controls. more...

Microbiota configuration dictates nutritional immune optimization [16s rRNA-seq]

(Submitter supplied) Mild or transient dietary restriction (DR) improves many aspects of health and aging. Emerging evidence from us and others has demonstrated that DR also optimizes the development and quality of immune responses. However, the factors and mechanisms involved remain to be elucidated. Here, we demonstrate that DR-induced optimization of immunological memory requires co-operation between memory T cells, the intestinal microbiota, and myeloid cells. more...

Estrobolome dysregulation is associated with altered immunometabolism in a mouse model of endometriosis

(Submitter supplied) Microbiome dysregulation affects the estrogen metabolism (estrobolome) profile which in turns affects the immunological response. Estrogen hormone is an essential hormone that regulates the sexual activity in females as well as immune response in both sexes. Endometriosis is one of complicated disorder influnce the fertility of females due to escape of endometrial tissue into peritoneal cavity where the immunotoxicity will be undertaken. more...

Effect of milk fat globules on growth and metabolism in rats fed an unbalanced diet

(Submitter supplied) We assessed the effects of supplementing milk fat globules (MFG) on the growth and development of the skeleton in rats fed a Western unbalanced diet (UBD). The UBD is high in sugar and fat, low in protein, fiber, and micronutrients, and negatively impacts health. The MFG—a complex structure secreted in milk—has a unique proteome and lipidome, and differs significantly from isolated dietary ingredients. more...

The protective role of TLR4 in intestinal epithelial cells through the regulation of the gut microbiota in DSS-induced colitis in mice

(Submitter supplied) Abstract. Background: The cause of ulcerative colitis (UC) is not yet fully understood. Previous research has pointed towards a potential role for mutations in NOD2 in promoting the onset and progression of inflammatory bowel disease (IBD) by altering the microbiota of the gut. However, the relationship between toll-like receptor 4 (TLR4) and gut microbiota in IBD is not well understood. To shed light on this, the interaction between TLR4 and gut microbiota was studied using a mouse model of IBD. more...
