The Involvement of Angiotensin Type 1 and Type 2 Receptors in Estrogen-Induced Cell Proliferation and Vascular Endothelial Growth Factor Expression in the Rat Anterior Pituitary

Figure 1

The influence of AT1 receptor antagonist losartan (L), AT2 receptor antagonist PD123319 (PD), and ACE inhibitor captopril (C) on diethylstilboestrol- (DES-) induced increase in number of PCNA immunopositive cells in anterior pituitary of rats. X Β± SEM; βˆ— 𝑃 < 0 . 0 5 versus C (DESβˆ’, control DES-untreated group), βˆ— βˆ— 𝑃 < 0 . 0 5 versus C (DES+, control DES-treated group), LI: labeling index (the number of PCNA-immunopositive cells per 1000 randomly scattered cells of anterior pituitary).
