Published: 1 October 2015
..., embryonic dorsal closure and pupal thorax closure in Drosophila are useful experimental models. We find that Pvr mutants have defects in dorsal midline closure with incomplete amnioserosa internalization and epidermal zippering, as well as cardia bifida. These defects are relatively mild in comparison...

...Ginger L. Hunter; Janice M. Crawford; Julian Z. Genkins; Daniel P. Kiehart We demonstrate that ion channels contribute to the regulation of dorsal closure in Drosophila , a model system for cell sheet morphogenesis. We find that Ca 2+ is sufficient to cause cell contraction in dorsal closure...

... of deafness in mammals. Here we show that the Drosophila myosin XV homolog, Sisyphus, is expressed at high levels in leading edge cells and their cellular protrusions during the morphogenetic process of dorsal closure. Sisyphus is required for the correct alignment of cells on opposing sides of the fusing...

..., we show that Drosophila Fer localises to adherens junctions in the dorsal epidermis and regulates a major morphological event, dorsal closure. Mutations in Src42A cause defects in dorsal closure similar to those seen in dfer mutant embryos. Furthermore, Src42A mutations enhance the dfer mutant...

... between the two cell types of the dorsal appendage primordia. In the embryo, Ed is absent from the amnioserosa during dorsal closure,generating an Ed expression border with the lateral epidermis that coincides with the actomyosin cable present at this interface. In both cases, ed mutant epithelia exhibit...

...Romi Biswas; David Stein; E. Richard Stanley Embryonic dorsal closure (DC) in Drosophila is a series of morphogenetic movements involving the bilateral dorsal movement of the epidermis (cell stretching) and dorsal suturing of the leading edge (LE) cells to enclose the viscera. The Syk family...

... that Src42A is essential for proper cell-cell matching during dorsal closure. Src42A, which is functionally redundant to Src64 , was found to interact genetically with shotgun , a gene encoding E-cadherin, and armadillo , a Drosophila β-catenin. Immunoprecipitation and a pull-down assay indicated that Src42A...
