Project description:Total RNA was extracted using TRI® Reagent (Sigma). cDNA was synthesized by RevertAid™ First Strand cDNA Synthesis Kit with Oligo dT primers (K1622, Fermentas) following manufacturer’s recommendations. PCR reactions were carried out on a DNAEngine® Thermal Cycler (PTC-0200G, Bio-Rad) in 25 μl reaction volume containing 1 μl cDNA, 200 nM primer pairs and components of TaKaRa Taq™ kit (R001A, Takara). All samples were analyzed in triplicate RT-qPCR.mRNAs were extracted using biotinylated poly(dT) oligo, followed by further removing of contaminated rRNA using RiboMinus Transcriptome Isolation Kit (K1550-02, Invitrogen). Then mRNAs were fragmented into 100-200nt length and subjected to immunoprecipitation with m6A specific antibody.The libraries were sequenced using HiSeq2000 (Illumina) in single-read mode, creating reads with a length of 101 bp. Sequencing chemistry v2 (Illumina) was used and samples were multiplexed in two samples per lane. discovery of the binding motif of m6a in normal, FTO deficient and five stages of adipogensis (D-2/0/2/5/10) in Mouse embryo fibroblast 3T3-L1 pre-adipocytes

Project description:In previous study, we demonstrated that adenine could activate AMPK signaling in 3T3 fibroblast. To investigate the changes of transcriptome in differential 3T3 cells by adenine stimulation, we used microarrays to analyze undifferentited annd differentiated 3T3-L1 adipocytes in mRNA levels.

Project description:Using RNA-Seq, we compared the transcriptomes of differentiated 3T3-L1 adipocytes for control and ZFP407-deficient cells Differentiated 3T3-L1 cells were electroporated with control or 1 of 2 Zfp407 siRNAs. Six independent siRNA electroporations were conducted for the control siRNA and 3 independent electroporations were conducted for each Zfp407 siRNA.

Project description:The LIM-domain-only protein FHL2 is a modulator of signal transduction and has been shown to direct the differentiation of mesenchymal stem cells toward osteoblasts and myocytes phenotypes. We hypothesized that FHL2 may simultaneously interfere with the induction of the adipocyte lineage. Therefore, we investigated the role of FHL2 in adipocyte differentiation using pre-adipocytes isolated from mouse adipose tissue and the 3T3-L1 (pre)adipocyte cell line. Here we report that FHL2 is expressed in pre-adipocytes and for accurate adipocyte differentiation, this protein needs to be downregulated during the early stages of adipogenesis. More specifically, constitutive overexpression of FHL2 drastically inhibits adipocyte differentiation in 3T3-L1 cells, which was demonstrated by suppressed activation of the adipogenic gene expression program as shown by extensive RNAseq analyses, and diminished lipid accumulation. To identify the protein-protein interactions mediating this repressive activity of FHL2 on adipogenesis, we performed affinity-purification mass spectrometry (AP-MS). This analysis revealed the interaction of FHL2 with the Nuclear factor of activated T-cells 5 (NFAT5), an established inhibitor of adipocyte differentiation. NFAT5 knockdown rescued the inhibitory effect of FHL2 overexpression on 3T3-L1 differentiation, indicating that these proteins act cooperatively. In conclusion, we present a new regulatory function of FHL2 in early adipocyte differentiation and revealed that FHL2-mediated inhibition of pre-adipocyte differentiation is dependent on its interaction with NFAT5.

Project description:Snail1 is a transcriptional repressor required for a correct embryonic development. In cancer, Snail1 promotes the epithelial to mesenchymal transition in tumorigenic epithelial cells. In this work, we have analyzed the control of Snail1 in the differentiation of the 3T3-L1 cell line derived from murine embryo cells. The activation by snail of 3T3-L1 induced typical markers of cancer-activated fibroblasts as S100A4 or CD44. We generated 3T3-L1 cells stably over expressing Snail1 (3T3L1/Snail1) and control (3T3-L1/control) cells. We used SILAC quantitative approach to identify and characterize protein alterations induced by Snail1. Cells were fractionated in 5 subcellular fractions. The nuclear fraction of the cells was separated by 10% SDS-PAGE. Gels with forward and reverse experiments were stained with Coomassie Blue and cut into 18 slices prior to reduction, alkylation and digestion with trypsin. Tryptic peptides were scanned and fragmented with a linear ion trap-Orbitrap Velos (ThermoScientific). We identified a total of 3108 proteins, with 2572 quantified proteins, and 565 proteins modulated >1.5-fold by Snail1 overexpression. Among them, we found interesting up-regulated proteins associated to early differentiation of adipogenesis (C/EBPβ) and down-regulated proteins implicated in the final stages of differentiation to adipocytes (Fatty acid-binding protein or Fatty acid synthase). We also observed as down-regulated proteins important mediators of PPARγ pathway. We also observed downregulation of proteins implicated in mTOR, SRC and JAK/STAT pathway. We validated these proteomics data by western blot and qPCR in 3T3-L1 cells and other types of fibroblasts with capable to differentiate to terminal mesenchymal phenotypes, as well as in mesenchymal stem cells (MSC). This work provided insight into novel proteins with potential roles in the regulation of differentiation of the 3T3-L1 and MSCs as Nr2F6, ASC-1, Prrx1 or Cbx6. These candidates are down regulated due to the overexpression of Snail1 in 3T3-L1 cells. We next investigated the potential binding of Snail1 to promoter of these candidates. In silico analysis with MatInspector program revealed various putative E-box consensus motifs for Snail1. We performed ChIP and Luciferase assay to validate Snail1 binds to different E-box motifs of our candidates. Additionally, we analyzed the ability to prevent the differentiation to adipocytes of the 3T3-L1 cells using siRNAs. This work provided insight into novel proteins with potential roles in the regulation of differentiation to adipocytes of the 3T3-L1 and mMSC cells as Nr2F6, ASC-1, Prrx1 or Cbx6 controlled by Snail1.
