Project description:Attainment of a brown adipocyte cell phenotype in white adipocytes, with their abundant mitochondria and increased energy expenditure potential, is a legitimate strategy for combating obesity. The unique transcriptional regulators of the primary brown adipocyte phenotype are unknown, limiting our ability to promote brown adipogenesis over white. In the present work, we used microarray analysis strategies to study primary preadipocytes, and we made the striking discovery that brown preadipocytes demonstrate a myogenic transcriptional signature, whereas both brown and white primary preadipocytes demonstrate signatures distinct from those found in immortalized adipogenic models. We found a plausible SIRT1-related transcriptional signature during brown adipocyte differentiation that may contribute to silencing the myogenic signature. In contrast to brown preadipocytes or skeletal muscle cells, white preadipocytes express Tcf21, a transcription factor that has been shown to suppress myogenesis and nuclear receptor activity. In addition, we identified a number of developmental genes that are differentially expressed between brown and white preadipocytes and that have recently been implicated in human obesity. The interlinkage between the myocyte and the brown preadipocyte confirms the distinct origin for brown versus white adipose tissue and also represents a plausible explanation as to why brown adipocytes ultimately specialize in lipid catabolism rather than storage, much like oxidative skeletal muscle tissue.

Project description:This study predicted flux differences between brown and white adipocytes by integrating the results of extracellular flux analyzers, such as the Seahorse Analyzer, with metabolic modeling. The microarrays of the individuals' preadipocytes were used to support the predictions. These are the same individuals who were assayed by microarray in GSE68544.

Project description:Secreted proteins from adipose tissue play a role in metabolic cross-talk and homeostasis. We performed high sensitivity mass spectrometry-based proteomics on the cell media of human adipocytes derived from the supraclavicular brown adipose and from the subcutaneous white adipose depots of adult humans. We identified 471 potentially secreted proteins covering interesting protein categories such as hormones, growth factors, extracellular matrix proteins and proteins of the complement system, which were differentially regulated in brown and white adipocytes. A total of 101 proteins were exclusively quantified in brown adipocytes and among these were ependymin-related protein 1 (EPDR1). Functional studies suggested a role for EPDR1 in thermogenic adipogenesis. In conclusion, we report substantial differences between the secretomes of brown and white human adipocytes and identify novel candidate batokines that can be important regulators of metabolism.

Project description:Brown adipose tissue (BAT) holds therapeutic potential for obesity and metabolic syndrome via increasing energy expenditure. Both inter- and intra-individual differences contribute to heterogeneity in human BAT and potentially to differential thermogenic capacity in human populations. Here, we demonstrated the generation of brown and white preadipocyte clones from human neck fat and characterized their adipogenic differentiation and thermogenic function. Combining a UCP1 reporter system and gene expression profiling, we defined novel sets of gene signatures in human preadipocytes that could predict the thermogenic potential of mature adipocytes. Knocking out the positive UCP1 regulators, PREX1 and EDNRB, in brown preadipocytes by CRISPRs markedly abolished the high level of UCP1 in mature brown adipocytes. Finally, we showed the ability to prospectively isolate adipose progenitors with great thermogenic potential. These data provide new insights into the cellular heterogeneity in human fat and offer clinically relevant gene targets that mark thermogenically competent preadipocytes.

Project description:Brown adipocytes are specialized for heat generation and energy expenditure as a defense against cold and obesity. Recent studies demonstrate that brown adipocytes arise in vivo from a Myf5-positive, myoblastic progenitor by the action of PRDM16. Here, we identified a brown fat-enriched miRNA cluster mir-193b-365 as a key regulator of brown fat development. Blocking miR-193b and/or miR-365 in primary brown preadipocytes dramatically impaired brown adipocyte adipogenesis whereas myogenic markers were significantly induced. Forced expression of miR-193b and/or miR-365 in C2C12 myoblasts blocked the entire program of myogenesis, and miR-193b induced myoblasts to differentiate into brown adipocytes. Mir-193b-365 was upregulated by PRDM16. Our results demonstrate that mir-193b-365 serves as an essential regulator for brown fat differentiation, in part by repressing myogenesis.
