Hypertrophy of cardiomyocytes was induced by AngII, this caused an increase in putrescine, spermidine and total polyamine pool in association with a decreased level of NO. Expressions of eNOS and PKG-I were down-regulated, [Ca2+]i was increased, and expressions of c-Fos and c-Myc upregulated. DFMO reversed these changes induced by AngII.Lin, Y., Liu, J.-C., Zhang, X.-J., Li, G.-W., Wang, L.-N., Xi, Y.-H., Li, H.-Z., Zhao, Y.-J., and Xu, C.-Q. (2010). Downregulation of the ornithine decarboxylase/polyamine system inhibits angiotensin-induced hypertrophy of cardiomyocytes through the no/cgmp-dependent protein kinase type-i pathway.
