The stretch of cardiac muscle increases developed force in two phases. The first phase occurs immediately after stretch and is the expression of the Frank–Starling mechanism, while the second one or slow force response (SFR) occurs gradually and is due to an increase in the calcium transient amplitude. Previously, we have shown that the SFR is the mechanical manifestation of an autocrine/paracrine mechanism activated by wall stretch involving growth factors-triggered reactive oxygen species (ROS) formation, and followed by redox-mediated cardiac Na+ /H+ exchanger (NHE1) activation leading to an increase in the Ca2+ "transient" amplitude. Recent own experiments assigned a role to thioredoxin-1 (“TRX1”, an important cellular antioxidant enzym...
