The main objective of this project was to characterize the spatial and temporal activation of signaling pathways for Ca2+/CaM/CaMKIIδC- and δB-kinases in defined subcellular areas of isolated adult ventricular cardiomyocytes and their influence on the initiation and progression of hypertrophy and heart failure. The project was performed on isolated rat cardiomyocytes and healthy and diseased human cardiomyocytes. This project enabled multidisciplinary collaboration of biologists, molecular biologists, biotechnologists and physicians from Austria and Serbia, which in the future will serve as a basis for the creation of a network of institutions for the development of modern approaches in experimental cardiovascular physiology. Complementarity of methods as well as scientific work and topics under in vivo and in vitro conditions of scientists from Austria and Serbia resulted in improvement of approach to solving problems in the field of cardiovascular physiology.
