[E-MTAB-366] Transcription profiling by array of chicken embryos at 15 different stages

ABSTRACT: 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.

Comparative transcriptome analysis reveals vertebrate phylotypic period during organogenesis.

Irie Naoki N Kuratani Shigeru S

Nature communications 20110101

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 co ...[more]

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.

Sexually dimorphic gene expression in the chick brain at stage 29

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.

Effects of antagonist of retinoid X receptor (UVI3003) on morphology and gene profile of Xenopus tropicalis embryos

Project description:Retinoid X receptor (RXR) plays an important role in the development of vertebrates, and the agonists of RXR are well-known to induce featured malformations in vertebrate embryos. However, there is no information about the teratogenicity of antagonists of RXR in vertebrate embryos. We exposed embryos of amphibian (Xenopus tropicalis) at stages 10/11 to a highly selective antagonist of RXR (UVI3003).

Chicken neural crest and neural plate

Project description:Neural cest cells are a transient stem cell-like population appearing during vertebrate embryonic development. Generation of the cranial neural crest is known to require a balanced combination of FGF and BMP levels. However, it is poorly understood how the functions of such growth factors are controlled in the extracellular spaces. Here we identifiy the extracelluar matrix protein anosmin (Gga.14976.1.S1_at, clone ChEST132d10) as a novel molecule synthesized locally in the cranial neural crest of chicken embryos. Cranial neural folds (NF) and ventral neural plates (NP) were dissected from Hamburger & Hamilton stage 8 (HH8) embryos (80 to 14 embryos, n=4), and total RNA was analyzed using a GeneChip chicken genome arrays (Affymetrix)
