Role of Egr1 in Skeletal Muscle Ischemia-Reperfusion Injury

Focus Area

Skeletal muscle is one of the most sensitive tissues to ischemic injury and the success of free flap and replantation surgery is dependent on the survival of this tissue following brief periods of ischemia. Tissue injury subsequent to ischemia-reperfusion (IR) insults is thought to be due to a cascade of cellular events that ultimately destroy skeletal muscle cells. While many of the cellular events of this cascade have been described, the molecular events that initiate this destructive cascade have not been elucidated in skeletal muscle tissue. The transcription factor early growth response protein-1 (Egr1) is a crucial mediator of inflammatory gene expression and has been shown to regulate IR injury in various organ models of IR injury. We propose that Egr1 contributes to skeletal muscle IR injury and will test this hypothesis using mice lacking a single copy or both copies of the Egr1 gene (Egr1 heterozygous, +/- and homozygous, -/- mice, respectively; Taconic). Further understanding of the mechanisms involved in mediating the effects of IR injury in skeletal muscle will aid in our ability to create a positive environment for muscle survival during procedures requiring free flap and replantation surgeries.
