Codonopsis pilosula is traditionally used to lower blood pressure. The purpose of our study is to investigate if C. pilosula attenuates AngII plus Leu(27)-IGFII-induced calcium influx and apoptosis in H9c2 cardiomyoblasts. C pilosula significantly attenuated AngII induced IGFIIR promoter activity. Leu(27)-IGFII was applied to enhance the Angll effect. C pilosula also reversed Ca2+ influx, MOMP and apoptosis increased by AngIl plus Leu(27)-IGFIL Molecular markers in IGFIIR apoptotic pathway (IGFIIR, calcineurin, etc.) and IGFIIR-G alpha q association were downregulated by C pilosula. However, p-Bad(Ser136) and BcI-2 were increased. Therefore, C pilosula suppresses Angll plus Leu(27)-IGFII-induced IGFII/IGFIIR pathway in myocardial cells. (C) 2012 Elsevier Ltd.
