Differential exudation of polypeptides by roots of aluminum-resistant and aluminum-sensitive cultivars of Triticum aestivum L. in response to aluminum stress
Download1994
Basu, A., Taylor, G. J., Basu, U.
Cultivars of Triticum aestivum differing in resistance to Al were grown under aseptic conditions in the presence and absence of Al and polypeptides present in root exudates were collected, concentrated, and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Upon exposure to...

Endogenous hypothalamic somatostatins differentially regulate growth hormone secretion from goldfish pituitary somatotropes in vitro
Download2003
Davis, P.J., Peter, R.E., Chang, J.P., Graves, C., Smith, S., Rivier, J.E., Yunker, W.Y., Unniappan, S.
Using Southern blot analysis of RT-PCR products, mRNA for three different somatostatin (SS) precursors (PSS-I, -II, and -III), which encode for SS14, goldfish brain (gb)SS28, and [Pro2]SS14, respectively, were detected in goldfish hypothalamus. PSS-I and -II mRNA, but not PSS-III mRNA, were also...

Endogenous melanocortin antagonist in fish: Structure, brain mapping and regulation by fasting of the goldfish agouti-related protein gene
Download2003
Cerdá-Reverter, J.M., Peter, R.E.
Agouti-related protein (AGRP) is a naturally occurring antagonist of melanocortin. In mammals, central AGRP expression is restricted to the arcuate nucleus in which it plays a key role in the control of energy balance by antagonizing melanocortin effects at melanocortin 4 receptors. In goldfish,...

Hypophysiotropic action of pituitary adenylate cyclase activating polypeptide (PACAP) in the goldfish: Immunohistochemical demonstration of PACAP in the pituitary, PACAP stimulation of growth hormone release from pituitary cells, and molecular cloning of goldfish pituitary type I PACAP receptor
Download1998
Shea, W.L.C., Wong, A.O.L., Chang, J.P., Tse, L.Y., Leung, M.Y., Chow, B.K.C.
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a member of the glucagon/secretin peptide family, and its molecular structure is highly conserved in vertebrates. In this study, the functional role of PACAP in regulating GH release in the goldfish was investigated. Using...

Molecular cloning, pharmacological characterization and brain mapping of the melanocortin 4 receptor in the goldfish: Involvement in the control of food intake
Download2003
Schioth, H.B., Cerdá-Reverter, J.M., Peter, R.E., Ringholm, A.
We report cloning, pharmacological characterization, tissue distribution, detailed brain mapping, and role in control of food intake of melanocortin 4 receptor in goldfish (gMC4R). The gMC4R protein has 68% identity with the human ortholog and is conserved in important functional domains....

Sherwood, N.M., Craig, A.G., Park, M., Powell, J.F., Carolsfeld, J., Chang, J.P., Fischer, W.H., Rivier, J.E.
The evolution of GnRH and the role of multiple forms within the brain are examined. Three forms of GnRH were purified from the brain of Pacific herring (Clupea harengus pallasi) and characterized using Edman degradation and mass spectrometry. Two forms correspond with the known structures of...

Primary structure of a novel gonadotropin-releasing hormone (GnRH) in the brain of a teleost, Pejerrey
Download2001
Somoza, G.M., Rivier, J.E., Fischer, W.H., Park, M.K., Chang, J.P., Craig, A.G., Montaner, A.D., Sherwood, N.M.
The neuropeptide GnRH is the major regulator of reproduction in vertebrates acting as a first signal from the hypothalamus to pituitary gonadotropes. Three GnRH molecular variants were detected in the brain of a fish, pejerrey (Odontesthes bonariensis), using chromatographic and immunological...
