Core Tip

Core tip: Although several reports have confirmed that proteolytic activity during cold storage determines graft outcome after transplantation, the effect of preservation solution on steatotic liver graft proteolysis and on the activation of ATP-dependent proteasome during cold ischemia injury has not been fully investigated. Here, we compared the effect of two preservation solutions Institut Georges Lopez-1(IGL-1) and University of Wisconsin on liver proteolysis and ubiquitin-proteasome activation when steatotic liver grafts were subjected to cold storage. We provide evidence for a protective role of proteasome and proteolysis inhibition using IGL-1 during steatotic liver graft preservation.
