LOHMANN, Kenneth J.; LOHMANN, Catherine M.F.; University of North Carolina at Chapel Hill; University of North Carolina at Chapel Hill: A Coastal Magnetic Map Used in Sea Turtle Navigation Sea turtles navigate long distances to specific geographic areas used as feeding grounds and nesting sites, but how they do so has remained enigmatic. It has […]

BECKMAN, BRIAN; SHIMIZU, MUNETAKA; GADBERRY, BRAD; PARKINS, PAUL; COOPER, KATHY; National Marine Fisheries Service; University of Washington; University of Washington; National Marine Fisheries Service; University of Washington: Temperature and the relations among plasma IGF-I, 41 kDa IGFBP, and growth in coho salmon. The effects of environmental variation on the IGF-I system and subsequently on growth […]

WOOD, AW; DUAN, C; Univ of Michigan, Ann Arbor: Targeted gene knockdown reveals an important role for insulin-like growth factor binding protein-2 in zebrafish embryonic development The insulin-like growth factor (IGF) system plays a central role in mediating fetal and postnatal growth in vertebrates. The major players in this hormone system are the peptide growth […]

DAVIS, K. B.; PETERSON, B.; HKD-SNARC/ARS/USDA, Stuttgart, AR; CGRU/ARS/USDA, Stoneville, MSLike: Insulin-Like Growth Factor and IGF Binding Proteins in Sunshine Bass Growth of fish is regulated by components of the pituitary-liver-somatic tissue axis. The influence of growth hormone from the pituitary is,in part, to stimulate the liver to synthesize and release insulin-like growth factors (IGF-I […]

PICHA, M.E.*; FRUCHTMAN, S.; NOGA, E.J.; BORSKI, R.J.; North Carolina State University, Raleigh: Increases in insulin-like growth factor-I during compensatory growth in a teleost fish Compensatory growth is an accelerated growth state that exceeds normal rates when animals are alleviated of certain growth-stunting conditions. Little is known of the hormonal control of compensatory growth in […]

DING, J; DUAN, C; Univ. of Michigan, Ann Arbor: IGF binding protein-5 is required for the pharyngeal skeleton formation in vivo IGFBPs are a conserved family of proteins that bind to IGFs and modulates IGF bioactivity. Some IGFBPs may also possess intrinsic biological activities that are IGF-independent. Their in vivo physiological functions of IGFBPs, however, […]

BREUNER, C.W.*; WADA, H.; SHYU, J.; LOVE, O.P.; University of Texas at Austin; University of Texas at Austin; University of Texas at Austin; Simon Fraser University: Corticosteroid Binding Globulin Capacity Responds to Chronic Hormone Treatment but not Acute Stressors There is increasing evidence that corticosteroid binding globulins (CBG) regulate glucocorticoid action in surprising and unpredictable […]

OLSSON, Lennart; ERICSSON, Rolf; Friedrich-Schiller-Universit�t Jena; Uppsala University: Three-dimensional morphogenesis of cranial musculature in lungfishes and amphibians Vertebrate head development is a classical topic that has received renewed attention during the last decade. Most reports use one of a few model organisms (chicken, mouse, zebrafish), and have focused on molecular mechanisms and the role of […]

DAVIDSON, B.J.*; LEVINE, M.S.; Univ. of California, Berkeley; Univ. of California, Berkeley: The way to a chordate�s heart is through its germ cells? Germ line silencing and other factors involved in Ciona intestinalis heart development. We are investigating heart development in the basal chordate Ciona intestinalis. Several cardiac genes, including the sole Ciona ortholog of […]

OAKLEY, T.H.; Univ. of California, Santa Barbara: The eye as a replicating and diverging developmental unit Sparked by new discoveries in developmental genetics, few topics have generated as much debate as eye evolution. This is somewhat surprising because the central controversy is not unique to eyes, but is a general theme of developmental genetics: evolutionarily […]
