Vertebrates have a unique 3D body shape in which correct tissue and organ shape and alignment are essential for function. For example, vision requires the lens to be centred in the eye cup which must in turn be correctly positioned in the head. Tissue morphogenesis depends on force generation, force transmission through the tissue, and response of tissues(More)
Budding uninhibited by benzimidazole-related 1 (BUBR1) is a central molecule of the spindle assembly checkpoint. Germline mutations in the budding uninhibited by benzimidazoles 1 homolog beta gene encoding BUBR1 cause premature chromatid separation (mosaic variegated aneuploidy) [PCS (MVA)] syndrome, which is characterized by constitutional aneuploidy and a(More)
Medaka is a small egg-laying freshwater fish that allows both genetic and embryological analyses and is one of the three vertebrate model organisms in which genome-wide phenotype-driven mutant screens were carried out (1). Divergence of functional overlap of related genes between medaka and zebrafish allows identification of novel phenotypes that are(More)
The medaka, Oryzias latipes, a small egg-laying freshwater fish, is one of the three vertebrate model organisms in which genome-wide phenotype-driven mutant screens have been carried out. Despite a number of large-scale screens in zebrafish, a substantial number of mutants with new distinct phenotypes were identified in similar large-scale screens in the(More)
In this video, we demonstrate the technique of microinjection into one-cell stage medaka embryos. Medaka is a small egg-laying freshwater fish that allows both genetic and embryological analyses and is one of the vertebrate model organisms in which genome-wide phenotype-driven mutant screens were carried out (1), as in zebrafish and the mouse. Divergence of(More)
