Project description:The goals were to investigate differences in gene expression between wild type and Gpr120 knockout mouse interscapular brown adipose tissue
Project description:Brown adipose tissue (BAT) thermogenesis and the browning of white adipose tissue are important components of energy expenditure. An RNAseq-based analysis of the mouse BAT transcriptome led us to identify GPR120 as a gene induced by thermogenic activation. GPR120, a G protein-coupled receptor binding unsaturated long-chain fatty acids, is known to mediate some beneficial metabolic actions of polyunsaturated fatty acids. We show that pharmacological activation of GPR120 induces BAT activity and promotes the browning of white fat in mice, whereas GRP120-null mice show impaired browning in response to cold. n-3 polyunsaturated fatty acids induce brown and beige adipocyte differentiation and thermogenic activation, and these effects require GPR120. GPR120 activation induces the release of fibroblast growth factor-21 (FGF-21) by brown and beige adipocytes and increases blood FGF21 levels. The effects of GPR120 activation are impaired in FGF21-null mice and cells. Thus, the lipid sensor GPR120 constitutes a novel pathway of brown fat activation and involves FGF21.
Project description:To identify transcriptomic differences in interscapular brown adipose tissue depots from HFD-challenged wild-type (WT) vs. Axl KO (whole-body Axl Receptor knockout) mice
Project description:Analysis of GPR120 which play roles for the fatty acid sensor in adipose tissue. Results provide insight into the transcriptional effects caused by the loss of the GPR120 proteins and provide further insight into their functions. GPR120 KO mice and the corresponding wild-type with normal diet(ND) or high fat diet(HFD), were subjected to Affymetrix Mus musculus microarrays. Epididymal adipose tissue and liver were analyzed in triplicates.
Project description:This project includes proteomic data of brown adipose tissue from high-fat diet-induced obese mice versus wild-type mice. WTB reprents the brown adipose tissue from wild-type mice.DIOB reprents the brown adipose tissue from diet-induced obesity mice.
Project description:This project includes proteomic data of brown adipose tissue from mice modeled with Cuprizone 300mg/Kg/Day for one month versus wild-type mice. CB represents the brown adipose tissue from wild type mice. MB represents the brown adipose tissue from mice treated with cuprizone.
Project description:We report the RNA expression of the mature brown fat from 6 week old wild type (WT) and PHOSPHO1 knockout (KO) mice. Mature brown fat was isolated from brown adipose tissue after collagenase digestion. Increased expression of mitochondrial genes is found in KO brown fat.
Project description:We performed RNA sequencing on brown adipose tissue in wild-type and Letmd1 knockout mice to investigate the gene expression patterns in Letmd1 deficient mice.
