ABSTRACT: 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.

Project description:The transcriptomes of immortalized anterior and posterior limb cell lines derived from E10.5 embryos were compared. Total RNA extracted from three E10.5 anterior and posterior limb cell line samples were compared.
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:The study compares two cell populations one where Etv2 is expressed and other lacks Etv2 expression. The cells from wild-type E9.5 hindlimbs , cells from Shh-EGFP E10.5 anterior hindlimbs , EGFP+ cells from Shh-EGFP E10.5 posterior hindlimbs, and EYFP+ cells from Etv2-EYFP transgenic E10.5 hindlimbs and forelimbs were collected and processed
Project description:Purpose: This study seeks to identify SMARCC1-bound regions in the mouse limb. Methods: To identify SMARCC1 bound regions in the limb, we performed Cut&Run on pooled anterior and posterior wild-type forelimbs at E11.5 (43-44s; 3 replicates each) and on whole forelimb pairs at E9.5 (21-24s; 2 replicates). We identified 28,082 SMARCC1-bound regions in the anterior forelimb at E11.5, 42,530 regions in the E11.5 posterior limb, and 10,792 SMARCC1-bound regions at E9.5 (FDR<0.05). Results: We find that SMARCC1 is bound to most limb enhancer regions at late stages (E11.5). Additionally, We find that SMARCC1 is bound to the majority of HH-responsive GLI enhancers at E11.5 but only a small portion of GLI enhancers at E9.5.
