Characteristics of differentiated newly identified adipose precursor cells

ABSTRACT: We have identified proliferative cells in adipose tissue expressing adipocyte specific genes, which were named small proliferative adipocytes (SPA). Comparison of gene expression among stromal vascular cells (SVC), SPA and mature adipocyte (MA) revealed that adipocyte specific genes and several neuronal genes were increased in the order of SVC < SPA < MWA. However, proliferin 2 (PLF) was detected only in SPA. We found that SPA changed to lipid laden cells by incubation with differentiation medium containing insulin/dexamethasone/IBMX. In this study, we investigated the gene expression of differentiated SPA (SPAD) comparing with differentiated SVC (SVCD). Microarrays and real time PCR revealed that uncoupling protein 1 (UCP1) and PLF were strongly expressed in D-SPA. These data suggested that SPA might be able to differentiate into beige cells.

RNA-Sequencing of wild type and UCP1-null beige adipose tissue

Project description:Since brown adipose tissue (BAT) dissipates energy through UCP1, BAT has garnered attention as a therapeutic intervention for obesity and metabolic diseases including type 2 diabetes. As we better understand the roles of classical brown and beige adipocytes, increased beige fat mass in response to a variety of external/internal cues is associated with significant improvements in glucose and lipid homeostasis that may not be entirely mediated by UCP1. We aim to analyze transcriptome of wild type and UCP1-null beige adipocyte to identify the UCP1-independent function.

scATAC-seq of Inguinal Adipose Tissue of UCP1-KO and WT mice.

Project description:Single cell level analysis of transcriptional circuits regulating UCP1-indepednent theremogensis through Lgr6 in inguinal Adipose tissue. We previously identified an increase in Lgr6 gene expression in the beige adipocyte population of UCP1-KO mice and hypothesized its involvement in UCP1-independent thermogensis. Consistent with our previous data the scATAC-seq data reveals that chromatin accessibility at the Lgr6 loci is significantly higher in Ucp1- KO beige adipocytes as compared to WT and the promter is also more accessible in Ucp1- KO beige adipocytes. Other DNA-binding motifs involved in UCP-1 indepedent thermogensis were also analyzed and found to be upregulated in the KO model.

Naa10p Inhibits Beige Adipocyte-mediated Thermogenesis through N-alpha-acetylation of Pgc1-alpha

Project description:We report that both conventional and adipose-specific Naa10p deletions in mice result in increased energy expenditure, thermogenesis, beige adipocyte differentiation and activation. Mechanistically, Naa10p acetylates the N-terminus of Pgc1-alpha and prevents it from interacting with Ppar[gamma] to activate key genes, such as Ucp1, involved in beige adipocyte function.

UCP1-dependent depletion of liver extracellular succinate antagonizes inflammatory pathogenesis

Project description:Non-alcoholic fatty liver disease (NAFLD) is the most prevalent liver pathology worldwide and is intimately linked with obesity and type 2 diabetes. Liver inflammation is a hallmark of NAFLD and is thought to contribute to tissue fibrosis and disease pathogenesis. Uncoupling protein 1 (UCP1) is exclusively expressed in brown and beige adipocytes and has been extensively studied for its capacity to elevate thermogenesis and reverse obesity. Here we identify an endocrine pathway regulated by UCP1 that antagonizes liver inflammation and pathology, independent of effects on obesity. We show that, without UCP1, brown and beige fat exhibit a diminished capacity to clear succinate from the circulation. Moreover, UCP1KO mice exhibit elevated extracellular succinate in liver tissue that drives inflammation through ligation of its cognate receptor succinate receptor 1 (SUCNR1) in liver-resident stellate cell and macrophage populations. Conversely, increasing brown and beige adipocyte content in mice antagonizes SUCNR1-dependent inflammatory signaling in the liver. We show that this UCP1-succinate-SUCNR1 axis is necessary to regulate liver immune cell infiltration and pathology, and systemic glucose intolerance in an obesogenic environment. As such, the therapeutic utility of brown and beige adipocytes, and UCP1, extends beyond thermogenesis and may be leveraged to antagonize NAFLD and SUCNR1-dependent liver inflammation.

Naa10p Inhibits Beige Adipocyte-mediated Thermogenesis through N-α-acetylation of Pgc1α

Project description:We reported that both conventional and adipose-specific Naa10p deletions in mice result in increased energy expenditure, thermogenesis, beige adipocyte differentiation and activation. Mechanistically, Naa10p acetylates the N-terminus of Pgc1α and prevents it from interacting with Ppar to activate key genes, such as Ucp1, involved in beige adipocyte function. We used microarrays to profile the gene expression changes by Naa10p KO in inguinal white adipose tissues (iWATs) derived from mice fed with high fat diet for 15 weeks.

A non-cell autonomous mechanism of beige adipocyte renaissance in subcutaneous adipose tissue

Project description:Two types of UCP1 positive cells-brown and beige adipocytes exist in mammals. Beige adipocytes are very plastic, and can be dynamically regulated by environment.Beige adipocytes formed postnatally in subcutaneous inguinal white adipose tissue (iWAT) lost thermogenic gene expression and multilocular morphology at adult stage, but cold could restore their “beigeing” characteristics, a phenomenon termed as beige adipocyte renaissance. Our results showed that beige cell maintenance and renaissance in adult mice were regulated by cAMP and HDAC4 signaling in white adipocytes non-cell autonomously. Genetic modulations of various components of this cAMP-HDAC4 cascade (e.g. LKB1) led to persistent browning and reduced adiposity independent of thermogenesis. To further study the mechanisms of beige adipocytes maintenance, we performed RNA-seq with samples from inguinal white adipose tissues of WT, AdipoqCre LKB1 F/F, and AdipoqCre LKB1 F/F; HDAC4 F/F mice.Our studies will move the beige adipocyte field forward and attract clinical applications to target beige adipocyte renaissance.

Immortalized clonal brown, beige and white adipose cell lines

Project description:Brown fat generates heat via the mitochondrial uncoupling protein UCP1, defending against hypothermia and obesity. Recent data suggest that there are two distinct types of brown fat: classical brown fat derived from a myf-5 cellular lineage and UCP1-positive cells that emerge in white fat from a non-myf-5 lineage. Here, we report the isolation of “beige” cells from murine white fat depots. Microarray analysis of the differentiated clonal inguinal and interscapular adipocytes in the presence of forskolin (10mM). These samples were profiled using Affymetrix mouse 430 2.0 arrays, 26 samples in total.

Genome-wide mapping of H3K4me1 status in primary adipocytes isolated from wild-type (WT) and Lonp1-knockout (LONP1 AKO) mice

Project description:Mitochondrial proteases are emerging as key regulators of mitochondrial plasticity acting both as protein quality surveillance and regulatory enzymes by performing highly regulated proteolytic reactions. It remains unclear, however, whether the regulated mitochondrial proteolysis is mechanistically linked to cell identity switch such as white-to-beige conversion of adipocytes. We found that disruption of LONP1-dependent proteolysis substantially impairs thermogenic molecular program and cellular respiration in in vitro differentiated primary adipocytes. qPCR analysis showed that expression levels of Ucp1 and other beige adipocyte thermogenic genes were remarkably downregulated in LONP1 AKO adipocytes. We took a deeper dive into the characterization of histone modifications in LONP1 AKO adipocytes using the global enhancer marker H3K4me1 ChIP-Seq. These unbiased ChIP seq data are strong evidence of that LONP1 loss results in decreased H3K4me1 on a broad array of thermogenic genes. These results collectively indicate that LONP1 is crucial to maintain proper epigenetic homeostasis and beige thermogenic gene expression.

Facultative protein selenation controls redox sensitivity, adipose tissue thermogenesis and obesity

Project description:Oxidation of cysteines by reactive oxygen species (ROS) initiates thermogenesis in brown and beige adipose tissues. Cellular selenols, where sulfur is replaced with selenium, exhibit enhanced reactivity with ROS. Here we developed a mass spectrometric method to interrogate incorporation of selenols into proteins. Unexpectedly, this approach revealed facultative incorporation of selenium into proteins that lack canonical encoding for selenium-containing amino acids. Selenium was selectively incorporated into regulatory sites on key metabolic proteins, including as selenocysteine replacing cysteine at position 253 in UCP1. Remarkably, dietary selenium supplementation elevated facultative incorporation into UCP1, elevated energy expenditure through thermogenic adipose tissue, and protected against obesity. Together, these findings reveal the existence of facultative protein selenation, which correlates with impacts on thermogenic adipocyte function.
