[Role of heat shock proteins, aldose reductase, Bcl-2 protein and microRNA in the mechanism of delayed preconditioning of heart].

Analysis of published data allows affirming that heat shock proteins (HSP) play an important role in the mechanism of cardioprotective effect of delayed preconditioning. However, HSP in all probability are non-end effectors but mediators of preconditioning because a peak of their levels in myocardium does not concur with maximal elevation of cardiac tolerance to impact of ischemia and reperfusion. There are bases to think that aldose reductase and Bcl-2 protein are claimants to the role of end-effectors of delayed preconditioning but microRNAs serve as mediators of forming increased cardiac tolerance to ischemia-reperfusion.
