We have analyzed the functional role of neuronal calcium sensor-1 (Ncs-1) in zebrafish development. We identified two orthologs of the mammalian NCS-1 gene. Full-length cDNAs encoding zebrafish Ncs-1a and Ncs-1b polypeptides were cloned and characterized. Whole-mount in situ hybridization revealed that ncs-1a mRNA was expressed beginning at early(More)
Hypotension after traumatic brain injury (TBI) worsens outcome. We published the first report of TBI plus hemorrhagic shock (HS) in mice using a volume-controlled approach and noted increased neuronal death. To rigorously control blood pressure during HS, a pressure-controlled HS model is required. Our hypothesis was that a brief, severe period of(More)
We have investigated the role of Na,K-ATPase genes in zebrafish ear development. Six Na,K-ATPase genes are differentially expressed in the developing zebrafish inner ear. Antisense morpholino knockdown of Na,K-ATPase alpha1a.1 expression blocked formation of otoliths. This effect was phenocopied by treatment of embryos with ouabain, an inhibitor of(More)
We have identified and characterized cDNAs encoding a novel zebrafish Na,K-ATPase alpha subunit. The full-length cDNA encodes a 1,023-amino-acid-long peptide which shows greatest homology to zebrafish alpha1 polypeptides. Radiation hybrid mapping localized the new gene (atp1a1a.5) to linkage group 1 in close proximity to the previously identified cluster of(More)
We have used whole-mount in situ hybridization to analyze Na,K-ATPase alpha and beta subunit gene expression in the developing zebrafish ear. Four alpha1-like (alpha1a.1, alpha1a.2, alpha1a.4, and alpha1a.5) and two beta (beta1a and beta2b) subunit genes are expressed in ear beginning at mid-somitogenesis. Each gene exhibits a distinct spatial and temporal(More)
Microstomia is the term used to describe a reduction in the size of the oral aperture that is severe enough to compromise quality of life, nutrition, and cosmesis. Few cases of congenital microstomia have been reported as most microstomia cases are due to burn injuries. We are presenting a case of a neonate who was found to be in respiratory distress with(More)
