Project description:Purpose: The goals of this study are to identify GPCRs that are endogenously expressed by high fat diet fed mouse adipose tissue, we subjected RNA prepared from isolated mouse adipocytes (iWAT and eWAT) and BAT tissue to RNA-seq analysis. Methods: Total RNA extracted from mature adipocytes (iWAT and eWAT) and BAT tissue of C57BL/6 mice maintained on high fat diet for 12 weeks were used to construct high throughput sequencing libraries. RNAs with RIN >8 (assessed by the Agilent 2100 Bioanalyzer system) were used to prepare transcriptome libraries using the NEBNext Ultra RNA library prep kit (New England Biolabs). High throughput RNA-sequencing was performed using a Illumina HiSeq 2500 at the NIDDK Genomic Core Facility (NIH, Bethesda, MD). Raw reads were mapped to the mouse (mm9) genome. Results: Our study demonstrated that mouse adipocytes/BAT tissue from HFD-fed mice express several GPCRs.
Project description:Purpose: The goals of this study are to identify Gs-linked GPCRs that are endogenously expressed by mouse adipose tissue, we subjected RNA prepared from isolated mouse adipocytes (iWAT and eWAT) and BAT tissue to RNA-seq analysis. Methods: Total RNA extracted from mature adipocytes (iWAT and eWAT) and BAT tissue of C57BL/6J mice (16-week old males) maintained on regular chow were used to construct high throughput sequencing libraries. RNAs with RIN >8 (assessed by the Agilent 2100 Bioanalyzer system) were used to prepare transcriptome libraries using the NEBNext Ultra RNA library prep kit (New England Biolabs). High throughput RNA-sequencing was performed using a HiSeq 2500 instrument (Illumina) at the NIDDK Genomic Core Facility (NIH, Bethesda, MD). Raw reads were mapped to the mouse (mm9) genome. GPCRs were extracted from the RNA-seq data using R form. Gs-coupled GPCRs were identified using the IUPHAR/BPS Guide to Pharmacology Database (https://www.guidetopharmacology.org/). Results: Our study demonstrated that mouse adipocytes/BAT tissue express several GPCRs that are selectively coupled to Gs, including the V2 vasopressin receptor, the glucagon receptor, and different melanocortin receptor subtypes.

Project description:Obesity has become a global health problem. Brown adipose tissue (BAT), specialized for energy expenditure through thermogenesis, potently counteracts obesity. Recently, BAT is also identified in human adults. We found that Lgr4 homozygous mutant (Lgr4m/m) mice display reduced adiposity and exhibit brown-like adipocytes in their WAT depots with higher expression of uncoupling protein 1 (Ucp1). Furthermore, Lgr4 ablation potentiates brown adipocyte differentiation from stromal vascular fraction (SVF) of epididymal WAT (eWAT) in vitro. We used microarrays to emxamine the gene expression profiles of the brown-like adipocytes differentiated from SVF of wild-type and Lgr4 mutant mice. We identified distinct gene expression profiles of these two groups. To demonstrate Lgr4 ablation can potentiate the differentiation of SVF from eWAT toward brown-like adipocytes in vitro, we isolated SVF from epididymal white adipose tissue (eWAT) of wild-type (WT) and Lgr4 mutant mice. We then plated SVF cells in 12-well plate, and differentiated them to brown adipocytes, followed by RNA extraction and hybridization with Affymetrix microarrays.
