Alterations in food intake and thyroid tissue content by corticotropin-releasing factor in Tinca tinca.
The present experiments test the effects of intracerebroventricular injections of ovine corticotropin-releasing factor (1 microgram) on food intake, plasma glucose levels and thyroid function at 8 h postinjection in tench. Food intake and thyroid triiodothyronine (T3) content were significantly decreased after CRF treatment. Thyroid thyroxine (T4) content and plasma glucose levels were not modified by this neuropeptide. The present results suggest that CRF plays a role on food intake regulation and thyroid gland activity in tench.
