ABSTRACT: Genome-wide analysis of brown adipose tissue gene expression of IL15-depleted mice under normal diet or diet enriched with the beta3-adrenergic agonist CL 316243
Project description:Chronic inflammation is one of the major players in the obesity related metabolic syndrome. However the various inflammatory mediators appear to promote insulin resistance directly or indirectly through their ability to induce the inflammatory cascade. Interleukin-15 (IL-15) is a pro-inflammatory cytokine that is involved in the pathogenesis of different autoimmune diseases such as rheumatoid arthritis, inflammatory bowel disease and type 1 diabetes. We postulated that as a pro-inflammatory cytokine, IL-15 promotes obesity during fat excess by promoting insulin resistance from tissues involved in energy metabolism. We used microarrays to characterize the gene expression profile of the brown adipose tissue of IL-15 mice under normal diet or diet enriched with the beta3-adrenergic agonist CL 316243 Total RNA obtained from adipose tissue of wt- or IL15-KO mice under normal diet or diet enriched with the beta3-adrenergic agonist CL 316243

Project description:We used microarrays to detail the gene expression profile during WAT -beige transition by treatment of beta adrenergic receptor agonist . Stromal vascular fractions (SVF) from mice (n = 3/group) that received vehicle or beta3 adrenergic receptor agonist, CL, treatment were served for RNA extraction and hybridization on Affymetrix microarrays. We are trying to find out angiogenic factors genes dynamics during white adipose tissues (WAT) - beige transition.
Project description:We performed RT-PCR panels analysis of microRNAs expression in exosomes from the serum of wt mice, cold exposed mice or beta3 Adrenergic receptor agonist (CL-316.243) treated mice, and in exosomes from culture medium of mature brown adipocytes with or without cAMP treatment. Several microRNAs were identified as indicator correlated to brown adipocytes activity. The selected microRNAs may become potential biomarkers of brown fat activation in vivo
Project description:Experiment designed to identify differences in gene expression profile in white adipose tissue upon stimulation by beta 3 adrenergic receptor agonist. This series compares 2 groups of C57BL/6J acutely treated with CL-316,243 or Saline for 3 hours.

Project description:A single cell suspension was generated from B3-adrenergic agonist (CL; 1 mg/kg/day) for 4 days and saline mouse SVF, and single-cell mRNAseq libraries were generated with Drop-Seq. A single cell suspension was generated from mouse mature adipocyte nuclei under the following conditions: RT, 24hrs @ 4 °C , 48hrs @ 4 °C, 4days @ 4 °C and B3-adrenergic agonist (CL; 1 mg/kg/day) and single-cell mRNAseq libraries were generated with 10X genomics.
