Gene expression changes in limb buds of Nipbl-haploinsufficient mice

ABSTRACT: Multiple genes are dysregulated in hindlimb buds of Nipbl-deficient embryos. In all, more than 1000 limb bud genes were found to be significantly altered in expression by microarray analysis of E10.5 mouse hindlimb buds. Small changes in expression (mostly decreases) were observed for genes involved in FGF, BMP, and SHH pathways, as well as numerous genes involved in the Wnt/planar cell polarity signaling pathway. Genes involved in the Mediator complex, Cohesin function, and Hox gene expression and functions were also dysregulated in Nipbl deficient limb buds. Microarray analysis using RNA extracted from E10.5 hindlimb limb buds harvested from stage-matched Nipbl+/- (n=12) and wildtype (n=12)

Bhlha9 deficiency effect in limb bud

Project description:Analysis of mouse limb bud (E10.5) lacking the Bhlha9 gene. Bhlha9 knockout mouse shows syndactyly and poliosis in the limb. This microarray results provides insight into the molecular mechanisms underlying Bhlha9 function in the limb development DNA microarray analysis was performed using Affymetrix mouse genome 430 2.0 array. RNA samples were obtained from the whole limb bud of the E10.5 wild-type and Bhlha9 knockout embryos described above. Total RNA (200 ng) was reverse-transcribed and biotinylated using the GeneChip 3â² IVT Express Kit (Affymetrix). The microarray data were summarized using the MAS 5.0 method.

Effects of the Sox17∆50 mutation on SOX17 function in mouse embryonic biliary development

Project description:To determine the role of specific cis-regulatory elements within the Sox17 endoderm-preferential TSS2 promoter, we generated Sox17∆50 mutant animals and surveyed how this mutation altered Sox17 expression. EPCAM+/CXCR4+ endodermal cells were isolated from E10.5 Sox17∆50/∆50 and Sox17+/+ embryos (n = 1 of each genotype). Posterior foregut and midgut regions of embryos were dissected by removal of embryonic head, heart, tail, limb buds, posterior and dorsal body trunk. Sox17+/+ and Sox17Δ50/Δ50 cell samples were labelled with barcodes from 3'CellPlex Kit (10X Genomics) and subsequently pooled together for single isolation, library preparation and sequencing.

Regulation of chondrogenesis in early murine limb mesenchyme by BMP signals

Project description:Numerous studies have established a critical role for BMP signaling in skeletal development. In the developing axial skeleton, sequential SHH and BMP signals are required for specification of a chondrogenic fate in somitic tissue. A similar paradigm is thought to operate in the limb, but the signals involved are unclear. To investigate the nature of these signals we examined BMP action in mesenchymal populations derived from the early murine limb bud (~ E10.5). These populations exhibited a graded response to BMPs, in which early limb mesenchymal (EL) cells (from the distal hind limb) displayed an anti-chondrogenic response, whereas BMPs promoted chondrogenesis in older cell populations. To better understand the molecular basis of disparate BMP action in these various populations, gene expression profiling with Affymetrix microarrays was employed to identify BMP-regulated genes. These analyses showed that BMPs induced a distinct gene expression pattern in the EL cultures versus later mesenchymal limb populations (IM and LT). Mouse embryos at gestational age E10.5 were collected and various portions of the limb were micro-dissected. These led to the generation of three populations of cells, early (EL) limb mesenchymal cells from the distal half of the hind limb, an intermediate (IM) population derived from the distal 1/3 of the fore limb, and a later (LT) population from the proximal 2/3 of the fore limb. Mesenchymal cells were isolated and cultured with and without BMP4 treatment. RNA was extracted from cultures at either Day 0,1 or 2, labelled and hybridized to Affymetrix 430 2.0 microarrays. For each time point, RNA was collected from two biological replicates for each treatment condition.

Transcription profiling of mouse developing hindlimb bud to identify genes controlled by LMX1B

Project description:A control vs. genetic knockout experiment aimed at determining what RNAs are upregulated or downregulated in e11.5 mouse proximal limb tissue lacking the Lmx1b gene. Because Lmx1b is required for dorsal-ventral patterning of the limb, this screen gives insight into what putative downstream targets of Lmx1b contribute to dorsal-ventral patterning. Experiment Overall Design: The proximal portion of e11.5 hindlimb buds (~500um) was used for RNA extraction. Each array was hybridized with pooled cRNAs from both hindlimb buds of three embryos (6 hindlimbs/sample).

A Switch Between Topological Domains Underlies HoxD Genes Collinearity in Mouse Limbs (ChIP-chip)

Project description:During limb development, Hoxd genes are transcribed in two waves: Early on, when the arm and forearm are specified and subsequently, when digits form. While the latter phase is controlled by enhancers centromeric to the HoxD cluster, we show here that the early phase requires enhancers located in the opposite telomeric gene desert. The transition between the two types of regulations involves a functional switch between two distinct topological domains, as reflected by a subset of genes mapping centrally into the cluster, which initially interact with the telomeric domain and subsequently shift to establish new contacts on the opposite side. This transition between two regulatory landscapes generates an intermediate area of low Hox dose developing into the wrist, the transition between our arms and our hands. This intriguing correspondence between genomic and morphological boundaries illustrates the mechanism underlying collinear Hox gene regulation in our developing appendages. Chromatin ImmoPrecipitation on chip (Tiling array): Distribution of H3K4me3 and H3K27me3 in early limb buds at E9.5, E10.5 and proximal late limbs E12.5.

Chip-chip from Mouse E10.5 anterior and posterior immortalised limb cell lines and limb tissue for H3K27me3 antibody and from Mouse E10.5 anterior and posterior limb tissue for Ring1B antibody.

Project description:Anterior-posterior differences in H3K27me3 and Ring1B enrichment over the 5 prime Hoxd genes in E10.5 murine distal forelimbs. Chromatin immunoprecipitation (ChIP) of H3K27me3 together with Ring1B and by ChIP-on-chip analysis demonstrated that over the 5 prime HoxD locus H3K27me3 enrichment is decreased and Ring1B enrichment is sparse in limb cells derived from the distal posterior forelimb bud of E10.5 mouse embryos. Array design includes 2 biological replicates for H3K27me3 in the cell lines and Ring1B in the limb tissue, and 2 biological replicates and 2 dye swap replicates for H3K27me3 in the limb tissue.
