RUB researchers find over active enzyme in failing hearts
Date:1/17/2013

the CaM kinase II determines cell stiffness

In further analyses, the research team also showed that a lack or an excess of CaM kinase II affected the stiffness of the muscle cells. Cells without the enzyme were stiffer, cells with the enzyme more flexible. If they added CaM kinase II to cells that were not able to produce the enzyme themselves, these relaxed. In failing human hearts, the team found increased activity of CaM kinase II in comparison with healthy hearts, and thus excessive phosphorylation in the PEVK and N2Bus titin regions. "This seems to alter the mechanical properties of the human heart muscle", says Wolfgang Linke.
