Developmental cis-regulatory analysis of the cyclin D gene in the sea urchin Strongylocentrotus purpuratus.
Cyclin D genes regulate the cell cycle, growth and differentiation in response to intercellular signaling. While the promoters of vertebrate cyclin D genes have been analyzed, the cis-regulatory sequences across an entire cyclin D locus have not. Doing so would increase understanding of how cyclin D genes respond to the regulatory states established by developmental gene regulatory networks, li...
متن کاملCis-regulatory control of the nodal gene, initiator of the sea urchin oral ectoderm gene network.
Expression of the nodal gene initiates the gene regulatory network which establishes the transcriptional specification of the oral ectoderm in the sea urchin embryo. This gene encodes a TGFbeta ligand, and in Strongylocentrotus purpuratus its transcription is activated in the presumptive oral ectoderm at about the 30-cell stage. Thereafter Nodal signaling occurs among all cells of the oral ecto...
متن کاملGenomic cis-regulatory logic: experimental and computational analysis of a sea urchin gene.
The genomic regulatory network that controls gene expression ultimately determines form and function in each species. The operational nature of the regulatory programming specified in cis-regulatory DNA sequence was determined from a detailed functional analysis of a sea urchin control element that directs the expression of a gene in the endoderm during development. Spatial expression and repre...
متن کاملModular cis-regulatory organization of Endo16, a gut-specific gene of the sea urchin embryo.
The Endo16 gene of Strongylocentrotus purpuratus is expressed at the blastula stage of embryogenesis throughout the vegetal plate, at the gastrula stage in the whole of the archenteron and in postgastrular stages only in the midgut. We showed earlier that a 2300 bp upstream sequence suffices to faithfully recreate this pattern of expression when fused to a CAT reporter gene. Here we define the ...
متن کاملAnalysis of cis-regulatory elements controlling spatio-temporal expression of T-brain gene in sea urchin, Hemicentrotus pulcherrimus
In sea urchin development, micromere descendants play important roles in skeletogenesis and induction of gastrulation. We previously reported that the T-brain homolog of sea urchin Hemicentrotus pulcherrimus, HpTb expresses specifically in micromere descendants and is required for induction of gastrulation and skeletogenesis. Thus, HpTb is thought to play important roles in the function of micr...
