NORBECK, L.; KITTILSON, J.; SHERIDAN, M.A.*; North Dakota State University, Fargo.; North Dakota State University, Fargo.; North Dakota State University, Fargo.: Nutritional Regulation of the Somatotropic Axis of Rainbow Trout (Oncorhynchus mykiss). Previously, we isolated and characterized the mRNAs that encode for major elements of the somatotropic axis of rainbow trout, including two forms of […]

CHRISTIANS, Julian K*; HOEFLICH, Andreas; KEIGHTLEY, Peter D; Simon Fraser University; Ludwig-Maximilians Universitaet; University of Edinburgh: Investigation of the causal gene underlying a quantitative trait locus (QTL) contributing to genetic variation in growth Within all species, many traits show continuous variation between individuals, with phenotype determined by both the environment and a potentially large number […]

BUCHHOLZ, D.R.*; PAUL, B.P.; SHI, Y.-B.; Laboratory of Gene Regulation, National Institute of Child Health and Human Development: Gene-specific changes in promoter occupancy by thyroid hormone receptor during frog metamorphosis: Implications for developmental gene regulation In all vertebrates, thyroid hormones (TH) affect post-embryonic developmental processes. The role of TH receptor (TR) in mediating the TH […]

HYNDMAN, K/A*; EVANS, D/H; University of Florida, Gainesville; University of Florida, Gainesville: Endothelin receptors in the killifish, Fundulus heteroclitus, gill The endothelin (ET) signaling cascade is traditionally viewed as three paracrines, ET-1, ET-2 and ET-3 that bind to two membrane bound receptors, ETA and ETB. Generally, when ETs bind to receptors on vascular smooth muscle […]

SILVER, M.R.*; SOWER, S.A.; University of New Hampshire; University of New Hampshire: Characterization of an ancestral type II GnRH receptor: function and pharmacological profile of the sea lamprey GnRH receptor Neuroendocrine regulation of reproduction in vertebrates is regulated by gonadotropin-releasing hormone (GnRH). GnRH acts on gonadotropes located in the anterior pituitary via its receptor, a […]

MCCORMICK, Stephen D.*; O’DEA, Michael F.; MOECKEL, Amy M.; USGS, Conte Anadromous Fish Research Center, Turners Falls MA USA; Organismic and Evolutionary Biology Program, University of Massachusetts, Amherst USA: Are we missing a mineralocorticoid in fish? Effect of corticoids and receptor inhibitors on salinity tolerance of Atlantic salmon. It has long been held that cortisol, […]

SERRAT, M.A.*; LOVEJOY, C.O.; KING, D.; Kent State University, OH; Kent State University, OH; NEOUCOM, Rootstown, OH: Age- and site-specific decline in IGF-I receptor expression and growth plate activity in the mouse hindlimb The proximal and distal growth plates of the principal long bones do not contribute equally to their longitudinal growth. Most hindlimb elongation […]

Meeting Abstract 53.5  Jan. 6  Identification of a potential ancient skin calmodulin gene from the sea lamprey ZHANG, Ziping*; LI, Weiming; Michigan State University zipingcn@msu.edu The development and structure of integument systems differ significantly between vertebrates and invertebrates. In vertebrates, keratinocytes undergo a complex and Ca2+ dependent differentiation to form a real skin. This process is absent […]

Meeting Abstract 53.1  Jan. 6  Genetic origins of parallel evolution in threespine and ninespine stickleback fish SHAPIRO, M.D.*; SUMMERS, B.R.; BALABHADRA, S.; BELL, M.A.; KINGSLEY, D.M.; Univ. of Utah; Stanford Univ.; Stanford Univ.; Stony Brook Univ.; Stanford Univ. shapiro@biology.utah.edu A longstanding question in the study of parallel evolution is whether the same gene or genes control similar […]
