RNA-seq Analysis of Gs-linked GPCRs expressed in mouse inguinal white adipocytes (iWAT), epididymal white adipocytes (eWAT) and brown adipose tissues (BAT)
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. Overall design: Inguinal white adipocytes (iWAT), epididymal white adipocytes (eWAT), and brown adipose tissues (BAT) were isolated from 16-week-old male C57BL/6J mice consuming regular chow (n=6)
