03-P096 In vivo analyzes of dystroglycan function during somitogenesis in Xenopus laevis
Dystroglycan (Dg) is a cell adhesion receptor for laminin that has been reported to play a role in skeletal muscle cell stability, cytoskeletal organization, cell polarity, and signaling. Here we show that Dg is expressed at both the notochord/somite and the intersomitic boundaries, where laminin and fibronectin are accumulated during somitogenesis. Inhibition of Dg function with morpholino ant...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولIntegrin Linked Kinase (X-ILK) Function during Embryonic Development and within Adult Tissues of Xenopus laevis
Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...
متن کاملEnhancer of split-related-2 mRNA shows cyclic expression during somitogenesis in Xenopus laevis
Somitogenesis is responsible for production of the segmented body plan typical of vertebrate embryos. The somites are blocks of mesoderm, produced by this process, that give rise to the vertebrae and ribs, the dermis of the skin and all the skeletal muscle of the body. Many genes that regulate somitogenesis have been identified in chick and mouse, whereas considerably fewer are known in Xenopus...

genes that control motor neuron induction, subtype identity, and target specificity. Mice were mutagenized with ENU and outcrossed to an HB9-GFP transgenic reporter line that expresses GFP in spinal motor neurons and their axons. Litters were analyzed by fluorescence microscopy for recessive mutations that affect motor neuron induction and motor axon projection pattern. We have screened 137 F1 ...
