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. Keywords: time course
Project description:Enhancer activation is essential for cell-type specific gene expression during cellular differentiation, however, how enhancers transition from a hypoacetylated “primed” state to a hyperacetylated-active state is incompletely understood. Here, we show SET domain-containing 5 (SETD5) forms a complex with NCoR-HDAC3 co-repressor that prevents histone acetylation of enhancers for two master adipogenic regulatory genes Cebpa and Pparg early during adipogenesis. The loss of SETD5 from the complex is followed by enhancer hyperacetylation. SETD5 protein levels were transiently increased and rapidly degraded prior to enhancer activation providing a mechanism for the loss of SETD5 during the transition. We show that induction of the CDC20 co-activator of the ubiquitin ligase leads to APC/C mediated degradation of SETD5 during the transition and this operates as a molecular switch that facilitates adipogenesis.
Project description:Target genes of Fbxl10 during 3T3-L1 adipogenesis was analyzed 3T3-L1 cells overexpressing Fbxl10 using retrovirus system containing LTR promoter were differentiated and RNA was extracted at day 2 of differentiation
Project description:Gene expression profiling of pre-adipocytes 3T3-L1 reveals anti-adipogenic potential to metabolic associated diseases through whole transcriptomic analysis. We evaluated the effects of Tsuruazuki extract on pre-adipocytes 3T3-L1. We performed an untargeted whole-genome transcriptome analysis to explore functionality of Tsuru on 3T3-L1 cells.
Project description:Transcriptional profiling of mouse 3T3-L1 adipocytes. The objective of this study is to explore gene expression profiles of 3T3-L1 adipocytes in response to GDE5 siRNA transfection.
