Description
Several reports suggested the activation of caspases in postmortem muscle implicating the onset of a caspase-dependent cell death process after animal bleeding. It has been further well established that apoptosis and necrosis are the two major cell death pathways. The questions addressed in the present work were as follows: (a) in postmortem muscle, do cells die as in vivo? and (b) if so, by which dying process this goal is achieved? Selected hallmarks of apoptosis (phosphatidylserine externalization (PS), cell shrinkage, actin degradation) were analyzed in postmortem rat muscles and compared to usual cell behavior in apoptotic and necrotic processes. Results presented clearly demonstrate a rapid PS externalization and cell shrinkage extending during the first 24 h postexsanguination together with a progressive degradation of cytoskeletal and thin filaments of actin. It was therefore concluded that, in postmortem muscle, cells commit suicide soon after animal bleeding through apoptosis. © 2010 Springer-Verlag.
