Energetic dependence of NPY-induced LH secretion in a teleost fish (Dicentrarchus labrax)

, : Energetic dependence of NPY-induced LH secretion in a teleost fish (Dicentrarchus labrax). American Journal of Physiology 277(6 Pt 2): R1627-R1634

Fasted juvenile sea bass (Dicentrarchus labrax) were injected intraperitoneally with pig neuropeptide Y (NPY) or NPY + glucose, whereas fed fish were injected with NPY alone. NPY alone or in combination with glucose induced a dose-dependent increase in LH secretion in fasted fish. Similar LH responses to NPY were observed in vitro in dispersed pituitary cells isolated from fed and fasted fish. Injection of NPY + glucose in fasted fish resulted in depletion of glucose.

We investigated whether, upon the integration of multiple copies of adenovirus type 12 (Ad12) DNA into an established mammalian (hamster) genome, the pattern of foreign DNA insertion would remain stable or change with consecutive passages of cells...
