Identification of genes characteristic of committed preadipocyte fibroblasts

ABSTRACT: In order to identify the molecular mechanisms controlling preadipocyte commitment we derived new sublines of Swiss 3T3 fibroblasts with varying potential for adipogenesis. Swiss 2, Swiss 8, Swiss 9, and Swiss 19 differentiate into fat cells while Swiss 3, Swiss 5, and Swiss 22 have a lower propensity to differentiate into fat cells. The overall goal was to identify genes whose expression in the fibroblast state correlates with the ultimate potential of the cells to undergo adipogenesis 4 preadipose fibroblast cell lines (Swiss 2, Swiss 8, Swiss 9, and Swiss 19 in triplicate or duplicate) were compared to 3 non-adipogenic fibroblast cell lines (Swiss 3, Swiss 5, Swiss 22 in triplicate)

Nature 20100303 7288

The worldwide epidemic of obesity has increased the urgency to develop a deeper understanding of physiological systems related to energy balance and energy storage, including the mechanisms controlling the development of fat cells (adipocytes). The differentiation of committed preadipocytes to adipocytes is controlled by PPARgamma and several other transcription factors, but the molecular basis for preadipocyte determination is not understood. Using a new method for the quantitative analysis of ...[more]

Transcription profiling of mouse 3T3-L1 fibroblasts differentiation during adipogenesis

Project description:3T3-L1 fibroblasts are a commonly used in vitro model for adipogenesis. When induced with hormones, they differentiate into mature fat cells. Here, microarrays were used to study 3T3-L1 adipose differentiation through time. Experiment Overall Design: 3T3-L1 fibroblasts were cultured in vitro and induced to differentiate using standard MDI protocol. At successive time-points, cells were collected, and processed for microarray analysis.

KD of Fibroblast specific TF

Project description:Combinatorial knock down of LHX9, OSR1, PRRX1, TWIST2, fibroblast specific transcription factors and adipogenic induction by medium change induce transdifferentiation from fibroblast to adipocyte. Adipogenesis from meshencymal stem cell (MSC) and human preadipocyte (PreADP) were used for general reference of adipogenesis. 54 Samples total with 3 replicates each of sample and treatment types.

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. Control mice YY1flox/flox versus YY1flox/flox; Ucp1Cre were fed a high fat diet for 3 months

Identification of genes characteristic of primary inguinal or epididymal preadipocyte fibroblasts

Project description:Committed preadipocyte fibroblasts were genetically labelled in transgenic mice by expressing GFP under the control of the locus for Zfp423, a gene controlling preadipocyte determination. These mice are herein referred to as Zfp423-GFP mice. The overall goal was to identify genes differentially expressed between adipogenic GFP+ firboblasts and non-adipogenic GFP- fibroblasts from either inguinal or epididymal fat stromal vascular cultures obtained from Zfp423-GFP mice. Adipose stromal vascular cultures were obtained from inguinal or epididymal fat of 6-8 week-old male Zfp423-GFP mice. GFP+ and GFP- fibroblasts were sorted from fat stromal vascular cultures and then returned to culture. Subconfluent cultures of GFP+ and GFP- cells were compared in triplicate for Affymetrix analysis.

Direct cell conversion from human dermal fibroblast to adipocyte

Project description:To investigate the effect of ZNF395 on adipogenesis, we tested whether ZNF395 enhance cell conversion from human dermal Fibroblast (FIB) to Adipocyte (ADP). PPARG2 was reported as a master regulator and can induce adipogenesis in non-adipogenic fibroblasts. We transduced PPARG2 with or without ZNF395 in FIB with lentivirus. Interestingly, co-transduction of PPARG2 and ZNF395 showed higher occurrence of adipocyte-like cells as compared with PPARG2 alone. Moreover, genes related with lipid metabolic process and lipid transport was significantly up-regulated in combination of PPARG2 and ZNF395. These results suggest that ZNF395 co-ordinate the transcriptional regulatory pathway with PPARG2, necessary for the induction of adipogenesis. Total RNA was obteined from human dermal fibroblast transduced with mock lentivirus vector (FIB_ctrl), PPARG2 (FIB_PPARG2) and co-transduced with PPARG2 and ZNF395 (FIB_PPARG2+ZNF395).

Development of a 3D fatty infiltration platform to model, at higher scale, the impact of LY2090314 compound on fibro/adipogenic progenitor adipogenic drift

Project description:In human dystrophies, the progressive muscle wasting is exacerbated by ectopic deposition of fat and fibrous tissue originating from fibro/adipogenic progenitors (FAPs). In degenerating muscles, the ability of these cells to adjuvate a successful healing is attenuated and FAPs aberrantly expand and differentiate into adipocytes and fibroblasts. Thus, arresting the fibroadipogenic fate of FAPs, without affecting their physiological role, represents a valuable therapeutic strategy for patients affected by muscle diseases. Here, using a panel of adipose progenitor cells including human-derived FAPs coupled with pharmacological perturbations and proteome profiling, we report that LY2090314 interferes with a genuine adipogenic program acting as WNT surrogate for the stabilization of a competent -catenin transcriptional complex. To predict the beneficial impact of LY2090314 in limiting ectopic deposition of fat in human muscles, we combined the Poly-Ethylene-Glycol-Fibrinogen biomimetic matrix with these progenitor cells to create a miniaturized 3D model of adipogenesis. Using this scalable system, we demonstrated that a two-digit nanomolar dose of this compound is effective to repress adipogenesis in a higher 3D scale, thus offering a concrete proof for the use of LY2090314 to limit FAP-derived fat infiltrates in dystrophic muscles.

Coordinated metabolic transitions and gene expression by NAD+ during adipogenesis.

Project description:Adipocytes are the main cell type in adipose tissue, a critical regulator of metabolism, highly specialized in storing energy as fat. Adipocytes differentiate from multipotent mesenchymal stromal cells through adipogenesis. Using RNA-seq we explored the effect of manipulating NAD+ bioavailability during adipogenic differentiation from human mesenchymal stem cells. Cells were harvested either undifferentiated (hMSC) or after days 8 and 16 of adipogenic induction. During adipogenesis, cells were treated with either NAD+ (5 mM), or FK866 (1 nM) or EX527 (50 μM).
