In an elegant set of genetic and biochemical experiments reported in this issue of Genes & Development, Bendig et al. (2006)
show that integrin-linked kinase (ILK) is a critical component of the cardiac stretch sensor. Their findings link the cell surface and actin cytoskeleton to central signaling pathways. Here we discuss the significance of this work in light of other recent discoveries on the molecular mechanisms of cardiac stretch sensing.
The heart has the extraordinary capability of responding to physiologic demand by rapidly altering the amount of blood pumped with each heartbeat. Similarly, in response to pathologic conditions, the
