Influence of ivabradine on reverse remodelling during mechanical unloading.

abstract：OBJECTIVE:In several cell types, proteasome inhibitors like carbobenzoxyl-leucinyl-leucinyl-leucinal (MG132) induce the 72 kDa heat shock protein (Hsp72) and exert cell protective effects. However, data in cardiomyocytes are currently lacking. METHODS AND RESULTS:We investigated the effects of MG132 in cultured neonat...
