Project description:The purpose of this experiment was to characterize the network of proteins that interact with TIA1, and to investigate whether tau exerts control over TIA1 protein interactions, TIA1 was immunoprecipitated from cortical brain tissue of 10 month-old WT (C57BL/6J), tau-/- and TIA1-/- mice. The specificity of the TIA1 IP was verified by immunoblotting with anti-TIA1 antibody (Fig. 3A), and the resulting TIA1 proteome was examined by mass spectrometry.

Project description:Gut microbiota and their metabolites influence host gene expression and physiological status through diverse mechanisms. Here we investigate how gut microbiota and their metabolites impact host's mRNA m6A epitranscriptome in various antibiotic-induced microbiota dysbiosis models. With multi-omics analysis, we find that the imbalance of gut microbiota can rewire host mRNA m6A epitranscriptomic profiles in brain, liver and intestine. We further explore the underlying mechanisms regulating host mRNA m6A methylome by depleting the microbiota with ampicillin. Metabolomic profiling shows that cholic acids are the main down-regulated metabolites with Firmicutes as the most significantly reduced genus in ampicillin-treated mice comparing to untreated mice. Fecal microbiota transplantations in germ-free mice and metabolites supplementations in cells verify that cholic acids are associated with host mRNA m6A epitranscriptomic rewiring. Collectively, this study employs an integrative multi-omics analysis to demonstrate the impact of gut microbiota dysbiosis on host mRNA m6A epitranscriptomic landscape via cholic acid metabolism.

Project description:Synbiotics are a combination of probiotics and prebiotics which can alter the composition of the gastrointestinal tract evoking beneficial effects throughout the body through the production of a battery of bioactive metabolites. In this study, a synbiotic was used to reduce the behavioral and biochemical symptoms of depression and this nanostring panel was used to decipher where along the gut-brain-axis the synbiotic-derived metabolites were invoking their beneficial effects on the immune system. The synbitoic was composed of two probiotic bacteria (Lactobacillus fermentum ATCC 793 and Bifidobacteria longum ATCC 15707 and a grape -derived prebiotic composed of grape seed polyphenol extract, resveratrol and a concord grape extract. Male mice (C57BL/6) were pretreatment with either nothing (control), BDPP, probiotic or synbiotic and underwent 28 days of chronic unpredicitable stress. After 28 days, animals' behavior reflected an increase in depressive- and anxiety-like behavior, rescued specifically by the synbiotic. This nanostring multiplex analysis reveals both tissue- and treatment-specific effects on immune modulators.

Project description:Eight 8-week-old male C57BL/6J mice were injected with adenovirus expressing Eepd1-Flag (3×10^8/mouse) into multiple sites in their iWAT. Three days later, each mouse was administered 50 mg/kg of myristic acid solution (prepared in 0.1% BSA) via oral gavage. Half of the mice were then exposed to 8°C for 16 hours in a cold chamber, while the other half remained at room temperature (4 mice per group).
