Project description:[E-MTAB-366] Transcription profiling by array of chicken embryos at 15 different stages
| PRJNA143263 | ENA
Project description:Transcription profiling of chicken development The experiment were perfomed as a part of our Vertebrate Evo-Devo project. The aim of the project is to compare transcription profiles of normal (unmanipulated, wild-type, whole embryo) vertebrate embryos. Total RNA was collected from wild type G.gallus whole embryos at 15 different stages (Stages:HH1,2,4,6,8,9,11,14,16,19,24,27,32,34,38), and hybridized to the Affymetrix Chicken Genome Array. All the stages contains data from two biological replications. Each staged-samples consists of pooled total RNA from several whole embryos.

Project description:One of the central issues in evolutionary developmental biology is how we can formulate the relationships between evolutionary and developmental processes. Two major models have been proposed: the 'funnel-like' model, in which the earliest embryo shows the most conserved morphological pattern, followed by diversifying later stages, and the 'hourglass' model, in which constraints are imposed to conserve organogenesis stages, which is called the phylotypic period. Here we perform a quantitative comparative transcriptome analysis of several model vertebrate embryos and show that the pharyngula stage is most conserved, whereas earlier and later stages are rather divergent. These results allow us to predict approximate developmental timetables between different species, and indicate that pharyngula embryos have the most conserved gene expression profiles, which may be the source of the basic body plan of vertebrates.

Project description:The purpose of this microarray experiment was to validate the Del-Mar 14K Chicken Integrated Systems Microarray for different chicken tissues and to determine the utility of this chicken cDNA microarray for other closely related and more distant avian species. The Del-Mar 14 K array was constructed from cDNAs amplified from EST clones sequenced from five normalized chicken cDNA libraries derived from neuroendocrine (5,929), abdominal fat (4,800), liver (2,635), skeletal muscle (2,398), reproductive tract (2,008), 387 long (70mer) oligonucleotides and 72 quality control spots. The array contains 17,770 cDNA clones, where protein matches were found by BlastX analysis for 68% of chicken contigs and 46% of singleton sequences represented on the array. A reference RNA design was used for the hybridization of total RNA from four chicken tissues (liver, abdominal fat, breast muscle and hypothalamus) and the cross-species hybridization (CSH) of total RNA from tissue from birds representing four orders of the Class Aves [Galliformes (chicken, Coturnix quail and domestic turkey), Anseriformes (Peking duck), Falconiformes (American kestrel) and Passeriformes (American tree sparrow)]. A reference RNA pool was made from an equal amount of high-quality total RNA extracted from chicken liver, abdominal fat, breast muscle and hypothalamus. Each of the 43 microarrays was co-hybridized with Cy3-labeled cDNA targets from one of the avian tissue samples and Cy5-labled cDNA targets from the reference chicken RNA pool. Loess-normalized data were used to determine the number of cDNAs expressed in chicken tissues and the number of genes (cDNAs) detectable by cross-hybridization with various avian tissue samples. The Cy5-labeled reference samples were used to determine the coefficient of variation across the 43 microarrays. This study shows a remarkably high level of cross hybridization of Cy3-labeled cDNA targets from a wide range of avian species to the Del-Mar 14K microarray, where 38 to 62% of the cDNA probes on the chicken array (genes) were detectable.

Project description:Biological bases for sexual differences in the brain exist in a wide range of vertebrate species, including the chicken. We examined whether sexually dimorphic gene expression in the brain precedes gonadal differentiation. Using the Affymetrix GeneChip® Chicken Genome Array, we identified many female- and male-enhanced genes that are differentially expressed in sex-specific brains from stage 29 chicken embryos. We postulate that these genes have potential roles in the sexual differentiation of neural function and development in chickens.

Project description:4 microarray time series was generated to identify cyclic genes of the segmentation clock in the mouse (2 time series), the chicken and the zebrafish. The right posterior half presomitic mesoderms (PSM) from 20 mouse embryos, 18 chicken embryos and 21 zebrafish embryos were dissected while the contralateral side of the embryo containing the left PSM was immediately fixed to be analyzed by in situ hybridization using a Lfng (fot mosue and chicken) or hes7 (zebrafish) probe to order the samples along the segmentation clock oscillation cycle. Probes were produced from RNA extracted from each of the dissected posterior half PSMs using a two-step amplification protocol and were hybridized to Affymetrix GeneChip MOE430A, MOE430 2.0, Affymetrix GeneChip chicken genome array, or Affymetrix GeneChip zebrafish array.
