Project description:Premetamorphic Xenopus laevis tadpoles limb bud cells respond to thyroid hormone by proliferation and subsequent differentiation. The goal of this experiment is to identify the genes involved in the TH-induced proliferation pathway in developing tadpole limb bud and compare it to TH-induced proliferation and differentiation program in tadpole brain. Xenopus tadpoles (NF54) were treated with 1 mM methimazole in 0.1 X MMR solution for 1 week to block the endogenous TH production and reduce the TH present in the system of the tadpole. They were then treated with 100 nM T3 in 1 mM methimazole and 0.1 x MMR for another 24h and 48h or without T3 for 48h (control group). Limb buds were dissected at the end of the experiment.

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.

Project description:Detailed information about stage-specific changes in gene expression is crucial for understanding the gene regulatory networks underlying development and the various signal transduction pathways contributing to morphogenesis. Here, we describe the global gene expression dynamics during early murine limb development, when cartilage, tendons, muscle, joints, vasculature, and nerves are specified and the musculoskeletal system of the limbs is established. We used whole-genome microarrays to identify genes with differential expression at 5 stages of limb development (E9.5 to 13.5), during fore-limb and hind-limb patterning. We found that the onset of limb formation is characterized by an up-regulation of transcription factors, which is followed by a massive activation of genes during E10.5 and E11.5 which tampers off at later time points. Among 3520 genes identified as significantly up-regulated in the limb, we find ~30% to be novel, dramatically expanding the repertoire of candidate genes likely to function in the limb. Hierarchical and stage-specific clustering identified expression profiles that correlate with functional programs during limb development and are likely to provide new insights into specific tissue patterning processes. Here we provide for the first time, a comprehensve analysis of developmentally regulated genes during murine limb development, and provide some novel insights into the expression dynamics governing limb morphogenesis. Fifty- one arrays were analyzed, consisting of whole fore-limb and hind-limb bud RNA (experimental) and whole embryo RNA (reference) samples from E9.5 to E13.5 DPC mouse (FVB strain). Embryos were not pooled to generate samples. Each time point has 3 to 5 biological replicates for limb bud samples, duplicates for whole embryos. Comparisons were made between limb bud samples and whole embryo at the same stage, fore-limb samples of different stages, hind-limb samples of different stages, and fore-limb samples compared to hind-limb samples at the same or the next stage.

Project description:Shh signal mediated by Gli family of transcription factors regulates digit growth and patterning in early limb development. Shh expression in the posterior margin of the limb bud defines the zone of polarizing activity. However, much less is know about downstream targets that mediate Shh signal functions. In this dataset, we include the expression data obtained from dissected anterior and posterior halves of mouse limb bud respectively. These data are used to obtain 889 transcripts that were upregulated 1.3 fold or more in the posterior limb bud, and 1189 transcripts that were enriched in the anterior limb bud at 1.3 fold or more.

Two samples were analyzed. We generate pairwise comparisons between anterior and posterior limb tissues. Genes with a fold-change ≥1.3 were selected.

Project description:Proper development of limb bud relies on the concordance of various signals, otherwise limb deformities occur. We report that heterogeneous nuclear ribonucleoprotein K (hnRNPK) is essential for limb bud development. here, we knock out Hnrnpk in limb bud and exert the RNA-seq, ATAC-seq, CUT&RUN-seq, and Hi-C assay using primary limb bud cells to explore the function of Hnrnpk in limb bud development.
