LONDRAVILLE, RL; KINTER, M; University of Akron; Lerner Research Institute, Cleveland Clinic Foundation: Immunopurification of anti-leptin reactive peptide from brain of green sunfish, Lepomis cyanellus We have isolated and sequenced peptides from fish brain that putatively align with mammalian leptins. Leptin is a small (16 kDa) protein hormone that influences fat storage, metabolic rate, onset […]

LI, S.; WAGNER, C. A.; FEI, H.; FRIESEN, J. A.; BORST, D. W.; Illinois State University, Normal: HMG-CoA reductase activity in the mandibular organ of the lobster, Homarus americanus 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the rate-limiting step in vertebrate isoprenoid synthesis. Since the lobster mandibular organ (MO) produces high levels of the sesquiterpene methyl farnesoate […]

SHIMIZU, M.*; HARA, A.; DICKHOFF, W.W.; Nat. Mar. Fish. Ser. and Univ. of Washington, Seattle; Hokkaido Univ., Hakodate, Japan; Nat. Mar. Fish. Ser. and Univ. of Washington, Seattle: Development of a radioimmunoassay for salmon 41-kDa insulin-like growth factor binding protein Insulin-like growth factor binding proteins (IGFBPs) are important modulators of IGF actions controlling IGF availability […]

AMEMIYA, Y*; YOUSON, J.H.; Univ. of Toronto at scarborough, Toronto, Canada; Univ. of Toronto at scarborough, Toronto, Canada: DIVERSITY OF THE STANNIOCALCIN MOLECULE Stanniocalcin (STC) is a homodimeric glycoprotein that was initially recognized as a product of the corpuscles of Stannius (CS) located within the kidneys of the holostean and teleostean fishes. It was later […]

KING, A.J.*; SCHMIDT, M.H.; ADAMO, S.A.; Dalhousie University, Halifax; IWK Health Sciences Centre; Dalhousie University, Halifax: The first use of ultrasound to image cardiovascular and respiratory structures in cuttlefish (Sepia officinalis, class Cephalopoda) Cephalopods have elevated metabolic rates and cardiovascular systems that are surprisingly similar to those of vertebrates. Oxygen transport, however, is constrained by […]

NICKERSON, J.G.*; DUGAN, S.G.; DROUIN, G.; MOON, T.W.; Univ. of Ottawa; Univ. of Ottawa; Univ. of Ottawa; Univ. of Ottawa: The β-Adrenergic Receptor System of the Rainbow Trout – Function and Molecular Biology. Our understanding of the β-adrenoceptor (β-AR) system in fish is based primarily on the use of mammalian-AR specific agonists and antagonists and […]

RIFFELL, J.A.*; ZIMMER, R.K.; Univ. of California, Los Angeles; Univ. of California, Los Angeles: Sex and the single cell: The relationship between flow microenvironment, gamete traits and fertilization success. Fertilization rate is an important factor mediating the production of offspring and, hence, population dynamics. For marine organisms that broadcast their sperm and eggs into the […]

BUCHHOLZ, D.R.*; HSIA, V.; FU, L.; SHI, Y.-B.; National Institutes of Health, Bethesda: In-vivo molecular mechanisms of thyroid hormone receptor during frog metamorphosis Frog metamorphosis is an excellent model to study in-vivo roles of thyroid hormone receptor (TR). Exogenous thyroid hormone (T3) acts as an “on” switch in premetamorphic tadpoles to initiate hormone-induced changes in […]

LEE, W-K; FEZZAA, K; WESTNEAT, M; BETZ, O; DONOHUE, K; Argonne National Laboratory; Argonne National Laboratory; Field Museum of Natural History, Chicago; University of Kiel, Germany; Harvard University: Imaging applications of synchrotron radiation for biomechanics and morphology The advent of third generation hard x-ray synchrotron facilities have greatly enhanced research in many fields. In biology, […]

HALE, ME; KHEIRBEK, MA; PRINCE, VE; Univ. of Chicago; Univ. of Chicago; Univ. of Chicago: Hox gene misexpression generates functional neurons in zebrafish locomotor neural circuits. Startle behaviors of fishes are initiated by neurons with cell bodies in the hindbrain and axons that extend along the length of the spinal cord. Such neurons include the […]
