The cloche and spadetail genes differentially affect hematopoiesis and vasculogenesis.
TLDR
The studies demonstrate that the molecular mechanisms that regulate hematopoietic and vasculogenic cells in normal zebrafish have been conserved throughout vertebrate evolution and the clo and spt genes are key regulators of these programs. Expand
Intraembryonic hematopoietic cell migration during vertebrate development.
TLDR
Findings support a hypothesis in which the hematopoietic program of vertebrates is established by variations in homologous migration pathways of extra- and intraembryonic progenitors. Expand
Solar UVB-induced DNA damage and photoenzymatic DNA repair in antarctic zooplankton.
TLDR
It is suggested that increased solar UV may reduce recruitment and adversely affect trophic transfer of productivity by affecting heterotrophic species as well as primary producers. Expand
Cloche, an early acting zebrafish gene, is required by both the endothelial and hematopoietic lineages.
TLDR
Results show that cloche is involved in the genesis and early diversification of the endothelial and blood lineages, possibly by affecting a common progenitor cell population. Expand
A Model for Cleavage Plane Determination in Early Amphibian and Fish Embryos
TLDR
A model to explain cleavage plane geometry in which the length of astral microtubules is limited by interaction with these boundaries, causing length asymmetries is proposed. Expand
Genomic remnants of alpha-globin genes in the hemoglobinless antarctic icefishes.
TLDR
It is proposed that the hemoglobinless phenotype of extant icefishes is the result of deletion of the single adult beta-globin locus prior to the diversification of the clade. Expand
A genomic fossil reveals key steps in hemoglobin loss by the antarctic icefishes.
TLDR
Surprisingly, a phylogenetically derived icefish species, Neopagetopsis ionah, possesses a complete, but nonfunctional, adult alphabeta-globin complex, which is concluded to be a "genomic fossil" that reveals key intermediate steps on the pathway to loss of hemoglobin expression by all ice fish species. Expand
Unexpected beta2-microglobulin sequence diversity in individual rainbow trout.
TLDR
Variation in the beta2m cDNA sequences is mainly at sites that do not perturb the structure of the maturebeta2m protein, showing that the observed diversity of the trout beta2M genes is not primarily a result of pathogen selection. Expand
Molecular and morphological phylogenies of the Antarctic teleostean family Nototheniidae, with emphasis on the Trematominae
TLDR
Four independent molecular data sets were sequenced in order to solve longstanding phylogenetic problems among Antarctic teleosts of the family Nototheniidae and show that the tendencies shown by some trematomines to secondarily colonize the water column are not gained through common ancestry. Expand
Cold Adaptation of Microtubule Assembly and Dynamics
TLDR
It is proposed that cold adaptation of microtubule assembly in Antarctic fishes has occurred in part by evolutionary restructuring of the lateral surfaces and the cores of the tubulin monomers. Expand
