ISSN: 1432-041XKeywords: Key words Homeobox gene ; Brain ; otd/Otx ; otp ; PlanarianSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Homeobox genes such as orthodenticle in Drosophila and its mouse homologues, Otx1 and Otx2, are known to be essential for rostral brain development. To investigate the molecular basis of brain evolution, we searched for otd/Otx-related homeobox genes in the planarian Dugesia japonica, and identified two genes, DjotxA and B, whose expression appears to be restricted to the cephalic ganglion (brain). DjotxA was expressed more medially, in the region containing the termini of the visual axons, and in the visual cells, suggesting involvement in establishment of the visual system. DjotxB was expressed in a discrete region just lateral to the DjotxA-positive domain, but not in the more lateral branch structures, which in turn are characterized by the expression of Djotp, a planarian homeobox gene related to mouse Orthopedia (Otp). In transverse sections of planarians, DjotxA and B expression were observed only at the anterior ends of the stumps, corresponding to the regional pattern of the regenerating brain. Our findings suggest that the planarian brain is composed of structurally distinct and functionally diverse domains which are defined by the discrete expression of the three evolutionarily conserved homeobox genes.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1432-041XKeywords: Cell-ECM interactions ; Hydrozoa Vertebrates ; XenograftsSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Extracellular matrices (ECMs) of phylogenetically very distant organisms were tested for their ability to support cell adhesion, spreading and DNA replication in reciprocal xenograft adhesion tests. Mechanically dissociated cells of the medusa Podocoryne carnea (Cnidaria, Hydrozoa) were seeded on ECMs of polyps and medusa, and on several ECM glycoproteins or entire ECMs from vertebrates. In reciprocal experiments, cells from different vertebrate cell-lines were seeded on ECMs of polyps, medusae and also on electrophoresed and blotted extracts of both types of ECMs. The results demonstrate that medusa cells adhere and spread on polyp and medusa ECMs but do not recognize vertebrate ECMs or purified ECM glycoproteins. Vertebrate cells in contrast adhere, spread and proliferate on ECMs of polyps and medusae. The number of attached cells depends on the cell type, the type of ECM and, in certain cases, on the stage of the cell cycle. Cell adhesion experiments with pretreated ECMs of polyps and medusae, e.g. oxidation of carbohydrate residues with sodium-metaperiodate, or blocking of certain carbohydrate moieties with the lectin wheat germ agglutinin or a carbohydrate-specific monoclonal antibody, demonstrate that ECM carbohydrates are more important for cell-ECM interactions of medusa cells than for vertebrate cells. Furthermore, the experiments indicate that polyp and medusa ECMs contain different components which strongly modulate adhesion, spreading and DNA replication of vertebrate cells.Type of Medium: Electronic ResourceURL:
