1. Análise da ação do ACTH e do peptídeo N-terminal da POMC na proliferação, morte celular e na expressão das proteínas de genes de resposta secundária na supra-renal de ratos hipofisectomisados ou tratados com dexametasona. / Analysis of ACTH and the peptide N-terminal POMC in proliferation, cell death, and expression of secondary response genes in adrenal glands of hypophysectomized or dexamethasone treated rats.
Different experimental models have been used to study the trophic action of ACTH in adrenal, which seems to be important in proliferation and cell death in vivo. This hypothesis was tested using hypophysectomized or dexamethasone treated rats, and through IHC we evaluate: 1-the BrdU incorporation in different adrenal cortex zone after i.p. of ACTH, FGF2 or N
