Long-term peripheral treatment of immature coho salmon (Oncorhynchus kisutch) with human leptin has no clear physiologic effect.
The effects of long-term peripheral exposure to recombinant human leptin were tested in immature coho salmon under both fed and fasted conditions. We found that high circulating levels of human leptin did not alter growth, energy stores, gonad weight, pituitary content of follicle-stimulating hormone, or plasma levels of insulin-like growth factor-I, insulin, growth hormone, or thyroxine.
