Project description:We used microarrays to detail the gene expression profile during WAT -beige transition by treatment of beta adrenergic receptor agonist . Stromal vascular fractions (SVF) from mice (n = 3/group) that received vehicle or beta3 adrenergic receptor agonist, CL, treatment were served for RNA extraction and hybridization on Affymetrix microarrays. We are trying to find out angiogenic factors genes dynamics during white adipose tissues (WAT) - beige transition.

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.

Project description:Background: Brown and white adipose tissues (BAT and WAT) play critical roles in controlling energy homeostasis and in the development of obesity and diabetes. Fsp27 is expressed in both BAT and WAT and promotes lipid storage and the development of obesity and diabetes. In addition, Fsp27-deficient white adipocytes acquired certain BAT-like properties including reduced lipid droplet size and increased mitochondrial activity. Using microarray and semi-quantitative real-time PCR analyses, we systematically analyzed the gene expression profile in Fsp27-deficient WAT and BAT. Results: We observed that BAT-selective genes were significantly up-regulated, whereas WAT-selective genes were down-regulated in the WAT of Fsp27-/- mice. Expression levels of BAT-selective genes were also dramatically up-regulated in the WAT of leptin and Fsp27 double deficient mice. Furthermore, we observed that expression levels of genes in multiple metabolic pathways including oxidative phosphorylation, the TCA cycle and fatty acid synthesis and oxidation were increased in the Fsp27-/- WAT. In contrast, expression levels for extracellular matrix remodeling, the classic complement pathway and TGF-β signaling"were down-regulated in the WAT of Fsp27-/- mice. Most importantly, regulatory factors that determine BAT identity such as CEBPα/β, PRDM16 and major components in the cAMP pathway were markedly up-regulated in the WAT of Fsp27-/- mice. Interestingly, we observed distinct gene expression profiles in the BAT of Fsp27-/- mice. Conclusion: Our data suggest that Fsp27 acts at upstream to control gene expression of diverse pathways, in particular the expression of regulatory factors that determine the identity of BAT and WAT. Therefore, Fsp27 is an important molecular determinant for the identity of WAT, and loss of Fsp27 leads to the conversion of WAT to a BAT-like tissue. Total RNAs were extracted from individual gonadal WAT of five pairs of 3-month-old wild-type and Fsp27-null male mice. Equal amounts of RNA from five pairs of mice with each genotype were pooled to form RNA pools (total 45 μg). Duplicate experiments were carried out.

Project description:To study the gene expression profiles of brown (BAT) and white (WAT) adipose tissues in wild type and LR11-deficeint mice. The four RNA sources, WT scWAT, Lr11 -/- scWAT, WT BAT and Lr11 -/- BAT, were prepared from subcutaneous WAT and BAT from wild-type mice and Lr11 -/- mice, respectively (n=3 each).
