Abstract:
Ischemia-reperfusion injury, including injury from warm- and cold-ischemia (CI) organ storage, remains a significant problem for all solid organ transplants. Suppressing CI damage would reduce delayed graft function and increase the donor organ pool size. PrC-210 has demonstrated superior prevention of damage in several preclinical studies as an immediate-acting free-radical scavenger. Here, we describe its profound efficacy in suppressing CI injury in a rat kidney model.
Methods:
Kidneys in 300 gm Sprague-Dawley rats were perfused in situ with UW solution with or without added PrC-210 and then stored at 4°C in the same solution for 0 to 48 hours. When procured, kidney-activated caspase-3 level (a marker of cell death) was measured, and direct histological analysis of kidneys was performed to assess PrC-210 protective efficacy. In vitro analyses of PrC-210-conferred protection to isolated rat kidneys or naked DNA were also performed.
Results:
A single 15 seconds in situ perfusion of kidneys with 20 mmol/L PrC-210 in UW solution resulted in significant reductions in (1) 30-hour CI-induced kidney-activated caspase level (P < 0.0001); activated caspase was reduced to levels not significantly different than control activated caspase levels seen in unperturbed kidneys, (2) 30-hour CI-induced renal Tubular Injury Scores (P = 0.0004) where brush border and tubular necrosis were markedly reduced, (3) PrC-210 conferred 100% protection against ·OH damage to naked DNA and isolated kidney mitochondria while current UW solution antioxidants were without protective effect.
Conclusions:
A single PrC-210-UW solution perfusion of rat kidneys upon removal from the rat profoundly reduced caspase and renal tubular injury in kidneys exposed to 30 hours of CI organ storage. These findings support further development of the PrC-210 molecule to suppress or to prevent ischemia-reperfusion injury in organ transplant and other ischemia-reperfusion injury settings.
