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:Metagenomic sequencing of mice with different treatments: Mice were randomly divided into donor control group (Donor + MRS), constipation model group (STC + MRS), or a Lactobacillus acidophilus treated group (STC + La): A humanized mouse model was established by intragastric administration of fecal bacterial liquid from healthy donors or STC patients on alternate days, followed by continuous administration of Lactobacillus acidophilus in treatment group. Finally, the feces of each group of mice were collected, and the intestinal microbial communities of the mice were analyzed through metagenomic sequencing. 16S rRNA sequencing of mice before and after the use antibiotics: Before and after treating the mice with antibiotics, the mice's feces were collected for 16s rRNA sequencing respectively.
Project description:Infection is a major complication and cause of mortality and morbidity after acute stroke however the mechanisms are poorly understood. After experimental stroke the microarchitecture and cellular composition of the spleen are extensively disrupted resulting in deficits to immune function. We used microarray to determine differentially expressed genes in the spleens of mice after experimental stroke to determine contributers to immunosuppression after stroke. We extracted RNA from spleens from 3 mice 5 d after experimental stroke when we have shown peak disruption to cellular composition and also from spleens from 2 sham-operated control mice for comparison.

Project description:The study investigated the impact of environment on the composition of the gut microbiota and mucosal immune development and function at gut surfaces in early and adult life. Piglets of similar genotype were reared in indoor and outdoor environments and in an experimental isolator facility. Mucosa-adherent microbial diversity in the pig ileum was characterized by sequence analysis of 16S rRNA gene libraries. Host-specific gene responses in gut ileal tissues to differences in microbial composition were investigated using Affymetrix microarray technology and Real-time PCR.
Project description:This study determined the influence of myeloid cell Trim59 deficiency on experimental stroke outcomes and the cerebral proteomic profile using myeloid cell Trim59 conditional knockout (Trim59-cKO) mice, the middle cerebral artery occlusion/reperfusion ischemic model, and a label-free quantitative proteomic profiling technique.
Project description:To explore the inner mechanism of components and combination of Qingkailing inject fluid,compare the gene express and pharmacological pathway after experimental stroke mice.
Project description:Tlx expression is upregulated after stroke, and stroke-induced neurogenesis is blocked when Tlx is inactivated. Tlx overexpression in NSCs leads to massive induction of neurogenesis via stroke, which leads to an improved motor function recovery. Four Tlx overexpressing mice, and 5 wild type mice as control. Technique repeat is done for one of the wild type mouse c1 to validate the quality of the data. Stroke are induced to all the mice by one side stratum ischemia.
Project description:Intermittent fasting is previously reported to exhibit neuroprotection against experimental ischemic stroke. However, the detailed understanding of protection mechanisms are lacking. By observing the overall transcriptomic changes in each timepoint of ischemic stroke would benefit the understanding of underlying active pathways and mechanisms. Here, we conduct experimental MCAO ischemic stroke on mice exposed to different daily intermittent fasting method to compare not only among the ischemic stroke timepoints but also the efficacy of different intermittent fasting interventions. Our current study presented the transcriptomic changes for the first time in specific timepoints of ischemic stroke as well as under the condition of intermittent fasting. A number of neuroprotective mechanisms-related genes were significantly affected by intermittent fasting conditions in differential manners.
