Project description:Age-related changes in macrophages are thought to underlie deleterious changes in adipose tissue during aging. RNAseq analysis of phagocyte-enriched and -depleted stromal vascular fractions of perigonadal white adipose tissue from young and aged mice revealed age-related differences in gene expression towards identification of adipose tissue macrophage-specific regulation.
Project description:Transcriptome analysis of white adipose tissue and bone (femur of the hind limbs) of the AEA001 mutant mouse. ENU generated mouse lines for osteoporosis. The mutation in the Ednra gene causes big ears and a flat short head. Due to a decreased body mass and a trend towards decreased glucose level white adipose tissue was analysed.
Project description:Excessive fat accumulation is a major risk factor for the development of type 2 diabetes.To determine the mechanisms by wich TP53INP2 regulates adipogenesis, gene expression profile was performed in perigonadal white adipose tissue fromTP53INP2-deficient mice.
Project description:Transcriptome analysis of white adipose tissue and bone (femur of the hind limbs) of the AEA001 mutant mouse. ENU generated mouse lines for osteoporosis. The mutation in the Ednra gene causes big ears and a flat short head. Due to a decreased body mass and a trend towards decreased glucose level white adipose tissue was analysed. Total RNA obtained from 4 male mutant mice was compared to 4 controls.
Project description:To investigate the global gene expression dynamics associated with short-term fasting, we used mRNA-seq to profile the transcriptomes of nine organs obtained from mice subjected to six different STF duration (0, 2, 8, 12, 18 and 22 hours of fasting; n=3 per time point; Fig. 1a). The nine organs profiled were: olfactory bulb (OB), brain (BRN, which includes the telencephalon and diencephalon), cerebellum (CBL), brainstem (BST, which consists of the mesencephalon, pons, and myelencephalon), stomach (STM), liver (LIV), interscapular brown adipose tissue (iBAT), perigonadal white adipose tissue (pgWAT), and posterior-subcutaneous white adipose tissue (psWAT).
Project description:White adipose tissue (WAT) harbors functionally diverse subpopulations of adipose progenitor cells that differentially impact tissue plasticity in a sex- and depot-dependent manner. To date, the molecular basis of this cellular heterogeneity has not been fully defined. Here, we describe a multilayered omics approach to dissect adipose progenitor cell heterogeneity from in three dimensions: progenitor subpopulation, sex, and anatomical localization. We applied state-of-the-art mass spectrometry methods to quantify 4870 proteins in eight different stromal cell populations from perigonadal and inguinal WAT of male and female mice and acquired transcript expression levels of 15477 genes using RNA-seq. Notably, our data highlight the molecular signatures defining sex differences in PDGFR+ preadipocyte differentiation and identify regulatory pathways that functionally distinguish adipose tissue PDGFRb+ subpopulations. The data are freely accessible as a resource at "Pread Profiler. Together, the multilayered omics analysis provides unprecedented insights into adipose stromal cell heterogeneity.
