Project description:This collection represents whole transcriptome data on human islets.. From this collection of human islets RNA-seq data we aim to identify the difference between gender, age, body mass index (BMI) at a transcriptomic level.

Project description:Obesity is a chronic, complex and multifactorial disease that has reached pandemia levels and is becoming a serious health problem. Intestinal microbiota is considered a main factor that affects body weight and fat mass, which points toward a critical role in the development of obesity. In this sense, probiotic bacteria might modulate the intestinal microbiota and the mucosal-associated lymphoid tissue. The aim of this study was to investigate the effects of L. paracasei, L. rhamnosus and B. breve feeding on the intestinal mucosa gene expression in a genetic animal model of obesity. We used microarrays to investigate the global gene expression on intestinal mucosa after the treatment with probiotic strains.

Project description:Transcriptional Profiling of Insulin Sensitive and Insulin Resistant Samples Sixty two participants at the tail ends of the distribution of insulin sensitivity adjusted for age, gender and natural logarithm of BMI for each ethnic group separately. Individuals at tail ends were well matched for age, gender, BMI, and percent fat, but were different for insulin sensitivity. Participants were of age 20 years to 55 years, body mass index (BMI) between 19 kg/m2 and 42 kg/m2, and had all biopsies obtained in the fasting state.

Project description:The human intestinal microbiota may play a role in the development of overweight and obesity. However, associations between saliva microbiota and body mass index (BMI) have been sparsely studied, although the oral cavity is the major gateway for microbes into the body. The aim of this study was to identify associations between the saliva microbiota and BMI categories in Finnish children aged 9-14 years.

Project description:Significant gut microbiota heterogeneity exists amongst UC patients though the clinical implications of this variance are unknown. European and South Asian UC patients exhibit distinct disease risk alleles, many of which regulate immune function and relate to variation in gut microbiota β-diversity. We hypothesized ethnically distinct UC patients exhibit discrete gut microbiotas with unique luminal metabolic programming that influence adaptive immune responses and relate to clinical status. Using parallel bacterial 16S rRNA and fungal ITS2 sequencing of fecal samples (UC n=30; healthy n=13), we corroborated previous observations of UC-associated depletion of bacterial diversity and demonstrated significant gastrointestinal expansion of Saccharomycetales as a novel UC characteristic. We identified four distinct microbial community states (MCS 1-4), confirmed their existence using microbiota data from an independent UC cohort, and show they co-associate with patient ethnicity and degree of disease severity. Each MCS was predicted to be uniquely enriched for specific amino acid, carbohydrate, and lipid metabolism pathways and exhibited significant luminal enrichment of metabolic products from these pathways. Using a novel in vitro human DC/T-cell assay we show that DC exposure to patient fecal water led to MCS -specific changes in T-cell populations, particularly the Th1:Th2 ratio, and that patients with the most severe disease exhibited the greatest Th2 skewing. Thus, based on ethnicity, microbiome composition, and associated metabolic dysfunction, UC patients may be stratified in a clinically and immunologically meaningful manner, providing a platform for the development of FMC-focused therapy. Fecal microbiome was assessed with Affymetrix PhyloChip arrays from patients with ulcerative colitis and healthy controls.

Project description:To characterize the effect of microbiota on global gene expression in the distal small intestine during postnatal gut development we employed mouse models with experimental colonization by intestinal microbiota. Using microarray analysis to assess global gene expression in ileal mucosa at the critical stage of intestinal development /maturation associated with weaning, and asking how expression is affected by microbial colonization In the study presented here, preweaned and postweaned GF, SPF mouse small intestinal total RNAs were used. Also, 3-week-old gnotobiotic mouse as well as GF mouse small intestinal RNAs were used.
