Journal ArticleDOI
Isolation and characterization of chum salmon growth hormone
Hiroshi Kawauchi,Syunsuke Moriyama,Akikazu Yasuda,Kazuo Yamaguchi,Kunikatsu Shirahata,Junko Kubota,Tetsuya Hirano +6 more
TL;DR: Two molecular forms of salmon growth hormone (sGH), sGH I and II, have been isolated from the pituitary glands of the chum salmon by a two-step extraction procedure subsequent to acid-acetone extraction, suggesting that they may be genetic variants coded on two separate genes.
Journal ArticleDOI
Isolation and partial characterization of a pair of prolactins released in vitro by the pituitary of a cichlid fish, Oreochromis mossambicus
Jennifer L. Specker,David S. King,Richard S. Nishioka,Kunikatsu Shirahata,Kazuo Yamaguchi,Howard A. Bern +5 more
TL;DR: HPLC and radio-HPLC analysis of [3H]leucine pulse-chase experiments reveal that each PRL is secreted in vitro at remarkably high rates and that the two PRLs are released in approximately equimolar amounts, suggesting the coordinate regulation of the secretion.
Journal ArticleDOI
Complete amino acid sequences of a pair of fish (tilapia) prolactins, tPRL177 and tPRL188.
Kazuo Yamaguchi,Jennifer L. Specker,David S. King,Yoshiharu Yokoo,Richard S. Nishioka,Tetsuya Hirano,Howard A. Bern +6 more
TL;DR: The complete amino acid sequences of a pair of tilapia (Oreochromis mossambicus) prolactins (PRLs) were determined and Circular dichroism spectra and hydropathy profiles suggest structural similarity of the two PRLs.

Tetsuro Kuga,Hiromasa Miyaji,Moriyuki Sato,Masami Okabe,Makoto Morimoto,Seiga Itoh,Motoo Yamasaki,Yoshiharu Yokoo,Kazuo Yamaguchi,Hajime Yoshida,Yoshinori Komatsu +10 more
TL;DR: In this article, a novel hG-CSF polypeptide derivatives having an amino acid sequence derived from the amino acid sequences of the human granulocyte colony stimulating factor polyPEptide by substitution of at least one amino acid by a different amino acid and/or deletion or insertion of another amino acid.
Journal ArticleDOI
Isolation of two forms of growth hormone secreted from eel pituitaries in vitro
Mitsuyo Kishida,Tetsuya Hirano,Junko Kubota,Sanae Hasegawa,Hiroshi Kawauchi,Kazuo Yamaguchi,Kunikatsu Shirahata +6 more
TL;DR: Both eGHI and eGHII were equipotent to ovine GH in promoting growth of juvenile rainbow trout and comparison of the partial N-terminal amino acids indicates that sequence 1 to 36 of GHII is exactly the same as 4 to 39 of GHI.
