Project description:The heartM-bM-^@M-^Ys rhythm is initiated and regulated by a group of specialized cells in the sinoatrial node (SAN), the primary pacemaker of the heart. Abnormalities in the development of the SAN can result in irregular heart rates (arrhythmias). Although several of the critical genes important for SAN formation have been identified, our understanding of the transcriptional network controlling SAN development remains at a relatively early stage. The homeodomain transcription factor Shox2 plays an essential early role in the specification and patterning of the SAN. Here, we compared gene expression levels in the right atria of wildtype and Shox2-/- hearts using microarray experiments to identify Shox2 target genes. Right atria of E11.5 mouse embryos were dissected and genotyped for RNA extraction. RNA from 6 embryos and 2 independent pregnancies was pooled per genotype (Wildtype and Shox2 Knockout) and compared.

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.

Project description:The goal of the experiment was to identify genes downstream of the SHOX2 transcription factor during mouse forelimb development. Triplicate Samples were isolated from Shox2 mutants and wildtype/heterozygote limbs at E10.5 and E11.5.

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. Limbs of E12.5 mouse embryos were dissected, fore- and hindlimbs were pooled and genotyped for RNA extraction. RNA from 3 embryos of 2 different pregnancies (in total 6 embryos) was pooled per genotype (Wildtype and Shox2 Knockout) and compared.

Project description:Atria and ventricles exhibit distinct molecular profiles that produce structural and functional differences between the two cardiac compartments. However, factors that determine these differences remain largely undefined. Cardiomyocyte-specific COUP- TFII ablation produces ventricularized atria that exhibit ventricle-like action potentials, increased cardiomyocyte size, and development of extensive T-tubules. We used microarrays to examine the molecular profile of cardiomyocyte-specific COUP-TFII knockout adult atria in comparison with that of normal atria. We extracted RNA from mutant right atria, control right atria and control ventricles from 2 months old adult mice, followed by gene expression profiling using Affymetrix microarrays.

Project description:Genetic and genomic research has greatly advanced our understanding of heart disease; yet a comprehensive map of the protein landscape of living human hearts is still lacking. Here we set out to identify the molecular basis of functional differences between human cardiac chambers by comprehensive protein expression quantification from samples collected in vivo by high-resolution mass spectrometry. Cardiac biopsies of right atria (RA), left atria (LA) and left ventricle (LV) were obtained from seven humans undergoing open chest surgery and analyzed by high-resolution mass spectrometry. We identify hundreds of proteins with a chamber specific expression pattern, supporting the different functional roles of the cardiac chambers, enabling identification of chamber specific drug targets, and offering novel links between genomic data and the mechanisms of disease.
