Implication

Compares the effects of hypothermic machine perfusion and static cold storage on kidney injury markers in a rat model, suggesting potential benefits of HMP.

Key Points

The study aims to understand the molecular mechanisms of hypothermic machine perfusion in reducing kidney injury compared to static cold storage.
Rat kidneys were preserved using either hypothermic machine perfusion or static cold storage.
Biochemical and histological analyses were performed after four hours of preservation.
Mitochondrial complex respiration and NDUFS3 expression were evaluated.
Histological staining assessed oxidative stress markers.
Increased NDUFS3 expression was observed in HMP-preserved kidneys compared to SCS and control groups.
SCS kidneys showed elevated levels of nitrotyrosine and kidney injury markers.
HMP preservation significantly reduced the increases in injury markers compared to SCS.
