Embryonic and larval development of the Drosophila mushroom bodies: concentric layer subdivisions and the role of fasciclin II.
Mushroom bodies (MBs) are the centers for olfactory associative learning and elementary cognitive functions in the arthropod brain. In order to understand the cellular and genetic processes thatExpand
Growth Regulation by Insulin-like Growth Factor-I in Fish
Insulin-like growth factor-I (IGF-I) is a mitogenic polypeptide that plays an essential role in the regulation of development and somatic growth of vertebrates, mainly by mediating growth hormoneExpand
Peptide purification, complementary deoxyribonucleic acid (DNA) and genomic DNA cloning, and functional characterization of ghrelin in rainbow trout.
We have identified ghrelin from the stomach of rainbow trout. Four isoforms of ghrelin peptide were isolated: the C-terminal amidated type of rainbow trout ghrelin (rt ghrelin) composed of 24 aminoExpand
The duality of fish gonadotropin receptors: cloning and functional characterization of a second gonadotropin receptor cDNA expressed in the ovary and testis of amago salmon (Oncorhynchus rhodurus).
We previously isolated a cDNA encoding a gonadotropin receptor (sGTH-R) from amago salmon (Oncorhynchus rhodurus) ovarian follicles. In the present study, we cloned a second gonadotropin receptorExpand
Cloning, functional characterization, and expression of a gonadotropin receptor cDNA in the ovary and testis of amago salmon (Oncorhynchus rhodurus).
A gonadotropin receptor was cloned from amago salmon (Oncorhynchus rhodurus) ovarian follicles. This receptor (sGTH-R) belongs to the glycoprotein hormone receptor family with a large extracellularExpand
Steroidogenic activities of two distinct salmon gonadotropins.
The effects of salmon gonadotropins, GTH I and GTH II, on production of two major steroid hormones in female salmonid reproduction, estradiol-17 beta and 17 alpha,20 beta-dihydroxy-4-pregnen-3-oneExpand
Characterization of melanin-concentrating hormone in chum salmon pituitaries
Many lower vertebrates exhibit colour change in response to the background. A dual hormonal control of colour change by two antagonistic pituitary melanophorotropic hormones was first postulated inExpand
Isolation and characterization of two distinct gonadotropins from chum salmon pituitary glands.
Two distinct gonadotropins, GTH I and GTH II, were extracted with 35% ethanol-10% ammonium acetate, pH 6.1, from female chum salmon pituitary glands, and purified by ion-exchange chromatography onExpand
Purification and characterization of gonadotropin I and II from pituitary glands of tuna (Thunnus obesus)
The duality of teleost pituitary gonadotropins was established in an advanced marine fish, the tuna (Thunnus obesus). Two different molecular forms of gonadotropins, designated tGTH I and tGTH II,Expand
Isolation and characterization of two coho salmon gonadotropins, GTH I and GTH II.
Two gonadotropins, GTH I and GTH II, were isolated from pituitaries of spawning coho salmon (Oncorhynchus kisutch) using sequential extractions with ammonium acetate (pH 9.0) and 40% ethanol,Expand
