Project description:We conducted 16S rRNA sequencing analyse on colonic contents to evaluate whether forced loss led to alterations in gut microbiota composition and function.
Project description:Gut microbiota were assessed in 540 colonoscopy-screened adults by 16S rRNA gene sequencing of stool samples. Investigators compared gut microbiota diversity, overall composition, and normalized taxon abundance among these groups.
Project description:A phylogenetic microarray targeting 66 families described in the human gut microbiota has been developped aud used to monitor the gut microbiota's structure and diversity. The microarray format provided by Agilent and used in this study is 8x15K. A study with a total of 4 chips was realized. Arrays 1 and 2: Hybridization with 100ng of labelled 16S rRNA gene amplicons from a mock community sample and 250ng of labelled 16S rRNA gene amplicons from 1 faecal sample. Each Agilent-030618 array probe (4441) was synthetized in three replicates. Arrays 3 and 4: Hybridization with 250ng of labelled 16S rRNA gene amplicons from 2 faecal samples. Each Agilent-40558 array probe (4441) was synthetized in three replicates.
Project description:The gut microbiota plays a critical role in host energy metabolism and immune regulation, yet the temporal dynamics of microbial community responses to acute physiological stressors remain poorly characterized. While exercise is recognized as a modulator of gut microbial composition, the immediate post-exercise shifts in microbial community structure across different genetic backgrounds have not been systematically examined. Here, we present a longitudinal 16S rRNA gene sequencing dataset profiling the temporal dynamics of gut microbiota following acute high-intensity exercise in two widely used laboratory mouse strains. Age-matched male BALB/c and C57BL/6J mice were subjected to a single bout of acute exercise. The colonic content samples were collected to capture early temporal responsesat. Total genomic DNA was extracted from colonic contents and the 16S rRNA V4 region was amplified and sequenced on the NovaSeq6000 platform. This dataset enables identification of strain-specific and conserved exercise-responsive microbial taxa, and supports functional predictions related to energy metabolism and intestinal homeostasis.
Project description:To explore the effects of gut microbiota of young (8 weeks) or old mice (18～20 months) on stroke, feces of young (Y1-Y9) and old mice (O6-O16) were collected and analyzed by 16s rRNA sequencing. Then stroke model was established on young mouse receive feces from old mouse (DOT1-15) and young mouse receive feces from young mouse (DYT1-15). 16s rRNA sequencing were also performed for those young mice received feces from young and old mice.
Project description:Gut microbial profiling of uterine fibroids (UFs) patients comparing control subjects. The gut microbiota was examined by 16S rRNA quantitative arrays and bioinformatics analysis. The goal was to reveal alterations in the gut microbiome of uterine fibroids patients.
Project description:To compare the similarities and differences in species diversity of the gut microbiota between the patients with melasma and healthy subjects. The feces were collected for 16S rRNA sequencing analysis of the gut microbiota.
