CRYAB and HSPB2 deficiency alters cardiac metabolism and paradoxically confers protection against myocardial ischemia in aging mice.

Abstract

The abundantly expressed small molecular weight proteins, CRYAB and HSPB2, have been implicated in cardioprotection ex vivo. However, the biological roles of CRYAB/HSPB2 coexpression for either ischemic preconditioning and/or protection in situ remain poorly defined. Wild-type (WT) and age-matched ( approximately 5-9 mo) CRYAB/HSPB2 double knockout (DKO… (More)
