Effect of deleting PexRAP/ADHAPR in adipose tissue of chow-fed male C57/BL6J mice

ABSTRACT: To investigate the role of PexRAP/ADHAPR in adipose tissue, we use adiponectin-driven Cre recombinase to delete Dhrs7b, the gene which encodes PexRAP/ADHAPR, from all adipose depots. This study assays gene expression in subcutaneous adipose tissue (iWAT) of 8 week old chow-fed male mice.

Whole ganglia RNA sequencing of C57 BL/6J mice

Project description:The study goal is to identify the gene expression profile of iBAT-related ganglia (SG/T1 & T3) and iWAT-related ganglia (T13/L1 & L2). RNA sequencing demonstrated clear separation of gene expression between brown adipose tissue related ganglia (SG and T3) and white adipose tissue related ganglia (T13/L1 and L2). Each sample type also showed clear separation from each other. No significant separation was observed in different genders.

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.

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.

Comparison of white adipose tissue and bone marrow adipose tissue from New Zealand White rabbits

Project description:Microarray analysis of white adipose tissue (WAT) and bone marrow adipose tissue (BMAT) from 22-week-old or 13-week-old male New Zealand White rabbits. From both cohorts, BMAT was sampled from the distal tibia (dBMAT) and the radius and ulna (ruBMAT), while WAT was sampled from the inguinal (iWAT) and gonadal (gWAT) depots. From the 13-week-old cohort, BMAT was also sampled from the proximal tibia (pBMAT). Sufficient RNA could not be isolated from all tissues for all rabbits, so for some rabbits only a subset of tissues is included.

MBOAT7-Driven Lysophosphatidylinositol Acylation in Adipocytes Contributes to Systemic Glucose Homeostasis

Project description:We previously demonstrated that antisense oligonucleotide (ASO)-mediated knockdown of Mboat7, the gene encoding Membrane Bound O-Acyltransferase 7, in the liver and adipose tissue of mice promoted high fat diet-induced hepatic steatosis, hyperinsulinemia, and systemic insulin resistance. Thereafter, other groups showed that hepatocyte-specific genetic deletion of Mboat7 promoted striking fatty liver and NAFLD progression in mice but does not alter insulin sensitivity, suggesting the potential for cell autonomous roles. Here, we show that MBOAT7 function in adipocytes contributes to diet-induced metabolic disturbances including hyperinsulinemia and systemic insulin resistance. We generated floxed Mboat7 mice and created hepatocyte- and adipocyte-specific knockout mice using Cre-recombinase mice under the control of the albumin and adiponectin promoter, respectively. After chow and high fat diet feeding (60% kCal fat), mice were subjected to metabolic phenotyping and tissues to molecular workup and analysis. Here, we show that MBOAT7 function in adipocytes contributes to diet-induced metabolic disturbances including hyperinsulinemia and systemic insulin resistance. The expression of Mboat7 in white adipose tissue closely correlates with diet-induced obesity across a panel of ~100 inbred strains of mice fed a high fat/high sucrose diet. Moreover, we found that adipocyte-specific genetic deletion of Mboat7 is sufficient to promote hyperinsulinemia, systemic insulin resistance, and mild fatty liver. Unlike in the liver, where Mboat7 plays a relatively minor role in maintaining arachidonic acid (AA)-containing PI pools, Mboat7 is the major source of AA-containing PI pools in adipose tissue. Our data demonstrate that MBOAT7 is a critical regulator of adipose tissue PI homeostasis, and adipocyte MBOAT7-driven PI biosynthesis is closely linked to hyperinsulinemia and insulin resistance in mice.

Exercise Training Remodels Inguinal White Adipose Tissue Through Adaptations in Innervation, Vascularization and the Extracellular Matrix

Project description:Inguinal white adipose tissue (iWAT) is essential for the beneficial effects of exercise training on metabolic health. The underlying mechanisms for these effects are not fully understood and here, we test the hypothesis that exercise training results in a more favorable iWAT structural phenotype. Using biochemical, imaging, and multi-omics analyses we find that 11-days of wheel running in male mice causes profound iWAT remodeling including decreased extracellular matrix (ECM) deposition, increased vascularization and innervation. We identify adipose stem cells as one of the main contributors to training-induced ECM remodeling, show that the PRDM16 transcriptional complex is necessary for iWAT remodeling and beiging, and discover neuronal growth regulator 1 (NEGR1) as a link between PRDM16 and neuritogenesis. Moreover, we find that training causes a shift from hypertrophic to insulin-sensitive adipocyte subpopulations. Exercise training leads to remarkable adaptations to iWAT structure and cell-type composition that can confer beneficial changes in tissue metabolism.
