Human subcutaneous adipose tissue and perithyroid adipose tissue gene expression

ABSTRACT: Different human adipose tissue depots may have functional differences. Subcutaneous human adipose tissue has been extensively studied, but less is known about other depots. Perithyroid (PT) adipose tissue contains not only white adipocytes but also brown adipocytes. The aim of this study was to compare the expression of brown adipocyte containing perithyroid adipose tissue with s.c. adipose tissue.role in the development of obesity. Expression profiling of adipose tissue may give insights into mechanisms contributing to obesity and obesity-related disorders.

Analysis of gene expression patterns in brown adipose tissue

Project description:Brown adipose tissue is a specialized fat tissue involved in heat generation by using a process termed thermogenesis. This ability to convert nutrient energy into heat sets brown adipocytes apart from the more common type of white adipocytes, which are mainly involved in energy storage. Brown adipose depots occur as a large interscapular depot in mice. Brown adipocytes are multilocular, i.e. contain many small lipid-filled vacuoles and uniquely express the uncoupling protein 1. In this study, the gene expression patterns in brown adipose tissue samples of young, healthy mice was analyzed.

Transcriptomics to discover splice variants involved in the browning of adipose tissue

Project description:Adipose tissue is the major depot for energy storage. Recent studies have shown that at least three types of adipocytes can be distinguished depending on their anatomical locations : 1) The classic brown adipocytes, i.e., brown adipose tissue (BAT); 2) The 'brite' (brown-in-white) adipocytes, i.e. inguinal white adipose tissue (iWAT); 3) The 'true' white adipocytes, i.e., epididymal white adipose tissue (eWAT). Two strains of mice (SV129 and C57BL/6J) were used in this study. SV strain is resistant to obesity and latter is prone to obesity. Pre-adipocyte cells were isolated from subcutaneous tissue (iWAT) to create four groups of cell cultures per strain of mouse.

Transgenic expression of BEN, a member of TFII-I family, in various murine adipose tissues

Project description:The white adipose organ is composed of both subcutaneous and several intra-abdominal depots. Excess abdominal adiposity is a major risk factor for metabolic disease in rodents and humans, while expansion of subcutaneous fat does not carry the same risks. Brown adipose produces heat as a defense against hypothermia and obesity, and the appearance of brown-like adipocytes within white adipose tissue depots is associated with improved metabolic phenotypes. Thus, understanding the differences in cell biology and function of these different adipose cell types and depots may be critical to the development of new therapies for metabolic disease. Here, we found that BEN, a determination factor of brown fat function. BEN transgenic mice displayed increased energy expenditure, limited weight gain, and improved glucose tolerance in response to a high-fat diet. These results demonstrate that BEN is a cell-autonomous determinant of a brown fat function and thermogenesis.

Hyaluronan mediates cold-induced adipose tissue beiging

Project description:Adipose tissue beiging refers to a process through which beige adipocytes emerge in classical white adipose tissue depots. Beige adipocytes dissipate chemical energy and secrete adipokines like classical brown adipocytes to improve systemic metabolism, which offers benefits for people with obesity and metabolic diseases. Cold exposure and β3-adrenergic receptor (AR) agonist treatment are two commonly used stimuli for increasing beige adipocytes in mice, but their underlying biological processes are different. Transcriptional analysis of inguinal white adipose tissue (iWAT) has revealed that changes in extracellular matrix (ECM) pathway genes are specific to cold exposure. Hyaluronic acid (HA), a non-sulfated linear polysaccharide produced by nearly all cells, is one of the most common components of ECM. We found that cold exposure significantly increases iWAT HA levels while β3-AR agonist CL316,243 fails to do so. Increasing HA level in iWAT by Has2 overexpression significantly increases cold-induced adipose tissue beiging; in contrast, decreasing HA by Spam1 overexpression, which encodes a hyaluronidase that digests HA, significantly decreases cold-induced iWAT beiging. All of these data implicate a role of HA in promoting adipose tissue beiging that is unique to cold exposure. Given the failure of β3-AR agonists in clinical trials for obesity and metabolic diseases, increasing HA could serve as a new approach to recruiting more beige adipocytes to combat metabolic diseases.

Microarray miRNA expression analysis of white and brown adipose tissue depots from mice exposed to cold or room temperature

Project description:In the last decades, adipose tissue has been defined to play a central role in the control of energy balance. Furthermore, the proven endocrine and thermogenic functions of adipocytes have renewed interest in the study of this tissue, as the activation of non-shivering thermogenesis may hold great potential for the future treatment of obesity and T2D. Cold exposure has defined to activate this process. Here, the miRNA transcriptomic response of epididymal and inguinal white adipose depots (eWAT and iWAT, respectively) as well as that of the interscapular brown adipose depot (iBAT) of C57Bl/6 mice either exposed to 22ºC or 4ºC for the period of 4 days were examined. This in-detail study of the adaptation of each depot to cold exposure has allowed unraveling depot-specific regulatory molecular mechanisms.

Gene expression data of brown-like adipocytes from Lgr4 homozygous mutant SVF

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.

Deep proteome profiling of white adipose tissue reveals marked conservation and distinct features between different anatomical depots

Project description:The two major mammalian adipose tissue depots are subcutaneous adipose tissue (SAT), which is associated with metabolic protection, and abdominal/visceral (VAT), which contributes to metabolic disease. To investigate the molecular underpinnings of these differences, we conducted a comprehensive analysis of the proteomes of adipocytes and whole tissue from these different depots across two different diets in male C57Bl/6J mice.

Effect of exosomes dervied from different adipose tissue on gene expression in 3T3L1 cells under high-low fat diet conditions

Project description:Exosomes derived from adipose tissues (AT-Exos) have been identified as a crucialmedium in the transmission of information from adipose tissue to itself and to other organs, including exosomes derived from inguinal white adipose tissue (iWAT-Exos), visceral white adipose tissue (vWAT-Exos) and brown adipose tissue (BAT-Exos). However, the functional differences in depot-specific AT-Exos under obese conditions remain elusive. Here we reported that AT-Exos participated in regulating adipocyte inflammation and metabolic homeostasis. Notably, vWAT-Exos play a critical role in promoting lipid accumulation and inflammation in the development of obesity. Although both are derived from “energy storage” WAT, the biological effects exhibited by iWAT-Exos are far different from those vWAT-Exos. Especially under diet-induced obesity conditions, iWAT-Exos appeared to be BAT-Exo-like, exhibiting an “energy expending” type. Altogether, our data indicated that AT-Exos from different depots have distinct functions and effects on adipocytes metabolism.
