The main objective of this study was to detect the steroidogenic effects of Ang II in bovine theca cells in vitro. Bovine theca cells were obtained from follicles (larger than 10mm of diameter) collected from a local abattoir and submitted to different treatments in a sequence of experiments. In experiment 1, CYP17A1 mRNA profile was evaluated in LH- (10ng ml-1) and Ang II-treated (0.1µM) theca cells. In experiment 2, a dose-response effect of Ang II (0.001; 0.1 e 10µM) plus insulin (100ng ml-1) and LH (100ng ml-1) was evaluated on steroidogenesis of bovine theca cells. Experiment 3 explored the effects of saralasin (an antagonist of Ang II receptors) on steroid production and steroidogenic enzymes regulation in theca cells. After 24 hours, culture media...
