Effects of Insulin-Like Growth Factor-I on In Vitro Final Oocyte Maturation and Ovarian Steroidogenesis in Striped Bass, Morone saxatilis1
Abstract Recombinant human (rh) insulin-like growth factor-I (IGF-I) was more potent than rhIGF-II at inducing in vitro germinal vesicle breakdown (GVBD), a marker for resumption of meiosis, inExpand

Prolonged fasting and cortisol reduce myostatin mRNA levels in tilapia larvae; short-term fasting elevates.
Myostatin negatively regulates muscle growth and development and has recently been characterized in several fishes. We measured fasting myostatin mRNA levels in adult tilapia skeletal muscle and inExpand

Temporal mRNA expression of transforming growth factor-beta superfamily members and inhibitors in the developing rainbow trout ovary.
During mammalian ovarian development transforming growth factor-beta (TGFbeta) superfamily members and their inhibitors are critical paracrine regulators, yet the intraovarian functions of theseExpand

Changes in whole-body thyroxine and triiodothyronine concentrations and total content during early development and metamorphosis of the toad Bufo marinus.
This study describes changes in the thyroid hormones thyroxine (T4) and triiodothyronine (T3) in the toad Bufo marinus during development from early embryonic stages through metamorphosis. Both theExpand

Isolation and characterization of myostatin complementary deoxyribonucleic acid clones from two commercially important fish: Oreochromis mossambicus and Morone chrysops.
In mammals, skeletal muscle mass is negatively regulated by a muscle-derived growth/differentiating factor named myostatin (MSTN) that belongs to the transforming growth factor-beta superfamily.Expand

In vitro actions of insulin-like growth factor-I on ovarian follicle maturation in white perch (Morone americana).
Previous studies of follicle maturation in temperate basses showed that insulin-like growth factor (IGF)-I and -II can induce meiotic resumption, indicated by germinal vesicle breakdown (GVBD), andExpand

Effects of short-term growth hormone treatment on liver and muscle transcriptomes in rainbow trout (Oncorhynchus mykiss).
Although studies have established that exogenous growth hormone (GH) treatment stimulates growth in fish, its effects on target tissue gene expression are not well characterized. We assessed theExpand

Endocrine and orexigenic actions of growth hormone secretagogues in rainbow trout (Oncorhynchus mykiss).
The effects of growth hormone secretagogues (GHSs) on the teleost somatotropic axis are poorly understood, particularly with respect to insulin-like growth factor-I (IGF-I) and the IGF-bindingExpand

Associations between Plasma Growth Hormone, Insulin-Like Growth Factor-I, and Cortisol with Stress Responsiveness and Growth Performance in a Selective Breeding Program for Rainbow Trout
Abstract The National Center for Cool and Cold Water Aquaculture is conducting a selective breeding program to improve the germplasm of rainbow trout Oncorhynchus mykiss for aquaculture. Two linesExpand
