Project description:We report the RNA expression of the mature brown fat from 6 week old wild type (WT) and PHOSPHO1 knockout (KO) mice. Mature brown fat was isolated from brown adipose tissue after collagenase digestion. Increased expression of mitochondrial genes is found in KO brown fat.
Project description:To study the role of Ybx2 in brown fat activity, we performed the RNA-seq data for wildtype and Ybx2 knockout brown fat under room temperature and upon cold exposure as well as for wildtype and Ybx2 knockout brown adipocytes culture from stromal vascular fraction cells. To determine the targets of Ybx2, we performed RNA immunopercipitatoin followed by RNA-seq
Project description:Brown fat dissipates energy as heat and protects against obesity. Here, we identified nuclear factor I-A (NFIA) as a novel transcriptional regulator of brown fat by a genome-wide open chromatin analysis of murine brown and white fat followed by motif analysis of brown-fat-specific open chromatin regions. NFIA and the adipogenic master regulator, PPARγ, co-localize at the brown-fat-specific enhancers. Moreover, the binding of NFIA precedes and facilitates the binding of PPARγ, leading to increased chromatin accessibility and active transcription. Introduction of NFIA into myoblasts results in brown adipocyte differentiation. Conversely, the brown fat of NFIA knockout mice displays impaired expression of the brown-fat-specific genes and reciprocal elevation of muscle genes. Finally, expression of NFIA and the brown-fat-specific genes is positively correlated in human brown fat. These results indicate that NFIA is a key transcriptional regulator of brown fat and exerts its effects by co-localizing with PPARγ at cell-type-specific enhancers.
Project description:We analyzed transcript abundance in interscapular brown and inguinal white adipose tissue of wildtype and UCP1-KO mice either adpated to 20°C or 30°C and fed a high fat or control diet.
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.

Project description:We performed RNA-Seq for brwon fat, epididymal white fat and soleus muscle of mice to identify brown fat-selective, white fat-selective and common fat genes. RNA-Seq for brown fat, white fat and soleus muscle of wild type C56BL6 mice.
Project description:We performed a genome-wide deep sequencing analysis of the microRNAs abundant in mesenchymal stem cells (MSCs) derived from murine brown adipose tissue and in in vitro differentiated mature brown adipocytes. Several microRNAs were identified as differentially regulated when comparing datasets from MSCs vs. mature fat cells. These microRNAs may have an implication in the regulation of adipogenesis as well as thermogenesis in brown adipose tissue (BAT).

Project description:We performed RNA sequencing on brown adipose tissue in wild-type and Letmd1 knockout mice to investigate the gene expression patterns in Letmd1 deficient mice.
