Project description:We have performed an RNA-seq experiment to identify expression and alternative splicing differences between WT and Mbnl3 isoform knockout mice E15 forelimbs. We have also identified and characterized transcriptome wide Mbnl3-binding sites in C2C12 cells and E15 forelimbs. 6 total samples were analyzed: E15 forelimbs from 3 WT and 3 MBNL3 M-NM-^TE2/M-NM-^TE2 female mice (15dpc). For HITS-CLIP, 3 samples each of C2C12 cells, WT E15 forelimbs and Mbnl3 ?E2 forelimbs were analyzed for Mbnl3 binding site analysis.
Project description:Forelimbs were manually dissected from three individual Bcl9/9l-deltaHD1/deltaHD2 mutants and three control littermates, at 10.5 days post coitum. BCL9 and BCL9L are paralogous beta-catenin cofactors involved in the transcriptional machinery of Wnt target genes.
Project description:Sonic hedgehog (Shh) signals via Gli transcription factors to direct digit number and identity in the vertebrate limb. We have characterized the Gli-dependent cis-regulatory network through a combination of whole genome ChIP-on-chip and transcriptional profiling of the developing mouse limb. In this dataset, we include the expression data obtained from dissected mouse forelimbs using a variety of gain- and loss-of-function hedgehog pathway mutants, as well as limbs dissected into responsive (posterior 2/3ds) and non-responsive (anterior 1/3d) Hh tissues. These data are used to obtain 753 genes that are differentially expressed in response to Shh signaling. Keywords: Comparison of genetic samples 28 Total samples were analyzed. We generated the following pairwise comparisons using PowerExpress: Shh<WT; SmoM2>WT; Gli3<WT; Gli3>WT; Ant<Post; Ant>Post. Genes with an FDRM-bM-^IM-$10% and a fold-change M-bM-^IM-%2 were selected. We did not generate pairwise comparisons for a certain combinations with SmoGli3 and Gli3 mutants because data from these arrays contained significant variability. To identify additional genes that were Shh-responsive, we performed the following multiple sample comparisons using an FDRM-bM-^IM-$10% and a posterior probability cutoff of M-bM-^IM-$25%: 1.) Ant<Post and Shh<WT<SmoM2, 2.) Ant<Post and Shh<WT<SmoM2 and Gli3>SmoGli3, 3.) Ant<Post and Shh<WT<SmoM2 and WT>SmoGli3
Project description:This study aims to look at gene expresion profiles between wildtype and Bapx1 knockout cells of the forelimbs in a E12.5 mouse embryo. Instead of looking at the whole forelimbs, only cells expressing Bapx1 were sorted by Fluroscent Activated Cell Sorting (FACS) and subjected to expression profiling by microarray.
Project description:We isolated ca. 500 forelimbs at 10 days post coitum, and performed ChIP-seq using anti-Bcl9 antibodies. Bcl9 is a beta-catenin transcriptional cofactor, therefore it allows the identification of binding sites of the canonical Wnt signalling-dependent transcriptional complex. This experiment allowed to define that, in this developmental context, Bcl9 acts as a beta-catenin dedicated partner. Moreover, it established a series of genome-wide Bcl9 (therefore Wnt/beta-catenin) tissue-specific target loci, thereby assessing the genetic relationship existing between Wnt signaling and other signalling cascades (e.g. the Bmp pathway).
Project description:We wanted to identify differentially expressed genes in wild-type forelimbs and forelimbs briefly exposed to Shh signaling. E10.25 forelimbs were cultured in control media and media containing cyclopmaine (inhibits the Hedgehog pathway) Generated two wild-type (control) and two cyclopmaine biological replicates for RNA-seq UT-Genome and Analysis Facility

Project description:The development of vertebrate extremities is a complex process which requires a highly coordinated network of different transcriptional activities. The homeodomain transcription factor Shox2 is a key player in limb formation controlling neural, muscular and skeletal development. Here, we compared gene expression profiles of wildtype and Shox2 knockout limbs using microarray experiments to identify Shox2 target genes. Forelimbs of E11.5 mouse embryos were dissected and genotyped for RNA extraction. RNA from 3-4 embryos of 2 different pregnancies was used for hybridisation to 2 arrays per genotype (wildtype and Shox2 knockout) and compared.
