Bulk RNAseq of Mus musculus Protein Kinase D1 (Prkd1) knock-out adipose tissue in response to thermoneutral and cold exposure stress

Project description:Brown adipose tissue (BAT) has in recent times been rediscovered in adult humans, and together with work from preclinical models, shown to have the potential of providing a variety of positive metabolic benefits. These include improved insulin sensitivity and reduced susceptibility to obesity and its various co-morbidities. As such, its continued study could offer insights to therapeutically modulate this tissue to improve metabolic health. It has been reported that adipose-specific deletion of the gene for protein kinase D1 (Prkd1) enhances mitochondrial respiration and improves whole-body glucose homeostasis. We sought to determine whether these effects were mediated specifically through brown adipocytes using a Prkd1 brown adipose tissue (BAT) Ucp1-Cre-specific knockout mouse model, Prkd1BKO. We unexpectedly observed that upon both cold exposure and beta-3-AR agonist administration, Prkd1 loss in BAT did not alter canonical thermogenic gene expression or adipocyte morphology. We took an unbiased approach to assess whether other signaling pathways were altered. RNAs from cold-exposed control and Prkd1BKO were subjected to RNA-Seq analysis. These studies revealed that myogenic gene expression is altered in Prkd1BKO BAT after both acute (8 hr) and extended (4 day) cold exposure. Given that brown adipocytes and skeletal myocytes share a common precursor cell lineage expressing myogenic factor 5 (Myf5), these data suggest that loss of Prkd1 in BAT may alter the biology of preadipocytes in this depot. The data presented herein clarify the role of Prkd1 in BAT thermogenesis and present new avenues for the further study of Prkd1 function in BAT.

Transcriptional control of thermogenesis by early B cell proteins [RNA-seq]

Project description:Early B Cell Factor 2 (EBF2) is required for brown adipose tissue basal thermogenic gene expression; however, it was unknown whether chronic cold exposure normalized the expression of thermogenic genes in Ebf2 mutant mice. We examined the transcriptome of Ebf2 WT and mutant brown adipose tissue in mice housed at room temperature or one week of cold exposure.

Histone Deacetylase 3 Prepares Brown Adipose Tissue For Acute Thermogenic Challenge [RNA-Seq]

Project description:Brown adipose tissue (BAT) is a thermogenic organ that requires Uncoupling Protein 1 (UCP1) to dissipate chemical energy as heat, to defend core body temperature against hypothermia, and counteract obesity and metabolic diseases1. However, the transcriptional mechanism ensuring BAT thermogenic capacity for survival prior to environmental cold is unknown. Here we show histone deacetylase 3 (HDAC3) is a required transcriptional regulator of BAT enhancers to ensure thermogenic aptitude and survival. Mice with genetic ablation of HDAC3 become severely hypothermic and fail to survive acute cold exposure. UCP1 is nearly absent in BAT lacking HDAC3 and there is marked down-regulation of mitochondrial oxidative phosphorylation (OXPHOS) genes. Remarkably, although HDAC3 canonically functions as a transcriptional corepressor2, HDAC3 functions as a coactivator of the estrogen-related receptor _ (ERR_) in BAT, and loss of HDAC3 leads to robust global down-regulation of ERR±-driven enhancers. HDAC3 coactivation of ERR_ is mediated through deacetylation of PGC-1_ and is required for basal transcription of Ucp1, OXPHOS, and Pgc-1_. Thus, HDAC3 uniquely primes Ucp1 and thermogenic gene transcription to ensure immediate BAT-driven thermogenesis upon acute exposure to dangerously cold temperatures.

Mus musculus brown adipose tissue histone proteoforms

Project description:Histones were isolated from brown adipose tissue and liver from mice housed at 28, 22, or 8 C. Quantitative top- or middle-down approaches were used to quantitate histone H4 and H3.2 proteoforms. See published article for complimentary RNA-seq and RRBS datasets.

Brown Adipose YY1 Deficiency Activates Expression of Secreted Proteins Linked to Energy Expenditure and Prevents Diet-Induced Obesity [BAT]

Project description:Analysis of brown adipose tissue from Yin Yang 1 (YY1) brown fat specific knockout mice fed a high fat diet for 3 months. YY1 deficiency in brown adipose tissue leads to strong thermogenic deficiency. The goal was to identify the genes controlled by YY1 responsible of brown fat defective function.

Human brown and white preadipocyes clonal dynamics predict themorgenic potential and function

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.
