- Controlo da secreção e síntese da hormona de crescimento e da prolactina em pituitárias de dourada (Sparus aurata L.) incubadas in vitroPublication . Brinca, Lilia; Power, DeborahO peixe utilizado no presente trabalho, a dourada (Spcnvs aura,a L), é uma espécie importante para a aquacultura ao longo de toda a costa mediterrânea. A hormona de crescimento (GH) e a prolactina (PRL) libertadas pela glandula pituitária deste teleósteo, regulam dum modo fundamental alguns processos fisiológicos particularmente o crescimento.
- Characterization of sea bream (Sparus aurata L.) prolactin and control of release from pituitary glandPublication . Brinca, Lilia; Power, DeborahThe sea bream {Sparus aurata L.) is an important aquaculture species along the Mediterranean coast. Prolactin (PRL) released by the pituitary gland play a central role in controlling several aspects of sea bream physiology. In this study, we examined the effect of several internai and externai factors on the activity of PRL cells in cultured pituitary glands. Sea bream pituitaries were cultured during 18hrs at 21ºC and the hormones present in the culture médium separated by SDS-PAGE. PRL was identified by Western blotting using antiserum directed against chum salmon PRL and quantified by optical densitometry.
