Project description:Brown adipocytes, muscle and dorsal dermis descend from precursor cells in the dermomyotome, but the factors that regulate commitment to the brown adipose lineage are unknown. Here, we prospectively isolated and determined the molecular profile of embryonic brown preadipose cells. Brown adipogenic precursor activity in embryos was confined to Pdgfrα+, Myf5Cre-lineage-marked cells. RNAseq analysis identified Early B Cell Factor-2 (Ebf2) as one of the most selectively expressed genes in this cell fraction. Importantly, Ebf2-expressing cells purified from Ebf2-GFP embryos or brown fat tissue did not express myoblast or dermal cell markers and uniformly differentiated into brown adipocytes. Interestingly, Ebf2-expressing cells from white fat tissue in adult animals differentiated into brown-like (or beige) adipocytes. Loss of Ebf2 in brown preadipose cells reduced the expression levels of brown preadipose-signature genes, whereas ectopic Ebf2-expression in myoblasts activated brown preadipose-specific genes. Altogether, these results indicate that Ebf2 specifically marks and regulates the molecular profile of brown preadipose cells. Embryonic fibroblasts, isolated from dorsal body wall of E14.5 Ebf2(GFP)/+ embryos, were further fractionated based on the expression of PDGFRα and Ebf2 (GFP). Affymetrix microarray analysis was prefromed,to compare the gene expression between PDGFRα+ Ebf2(GFP)- and PDGFRα+ Ebf2(GFP)+ cells.

Total mRNA profiles from Myf5-cre(GFP)+PDGFRα+ and Myf5-cre(GFP)+PDGFRα-Itga7+ cells were generated by deep sequenceing

Project description:The induction of beige/brite adipose cells in white adipose tissue (WAT) is associated with protection against high fat diet-induced obesity and insulin resistance in animals. The helix-loop-helix transcription factor Early B-Cell Factor-2 (EBF2) regulates brown adipose tissue development. We examined the role of EBF2 in beige fat cell biogenesis by comparing transcriptome in wildtype and EBF2-overexpressing mice in the adipose tissue. Four control replicates (wildtype) and four experimental replicates (Fabp4-Ebf2) mice were analyzed

Project description:The helix-loop-helix transcription factor Early B-Cell Factor 2 (EBF2) is required for the differentiation and function of brown and beige adipocytes. The presumptive BAT in Ebf2 knockout (KO) animals has a white-fat like morphology and molecular profile. We examined the transcriptome of WT and Ebf2 KO BAT by high-throughput sequencing.
