BACKGROUND: Renal transplant surgical proceedings are known to elicit periods of hypoxia and consequent blood flow reestablishment triggering ischemia-reperfusion (I-R) injury. Kidney damage induced by I-R injury associates with a higher risk of graft dysfunction and rejection. Anesthetic preconditioning exerts a beneficial effect on I-R injury by reducing oxidative stress, inflammation and apoptosis. However, the degree of renoprotection stimulated by commonly used anesthetics, as well as their mechanisms of action, are largely unknown. Sirtuins are class III histone deacetylases that reduce cellular stress, promote genome stability and regulate senescence. So far, the relationship between sirtuins and anesthetic preconditioning in the context of renal I-R has not been studied. The main objective of the present work was to determine the renal expression of sirtuins after I-R damage in rats under different anesthetic preconditioning treatments.
METHODS: Unilateral ischemia was performed via occlusion of the left renal hilum for 45 min and followed by 24 hours of reperfusion. Anesthetic preconditioning schemes (morphine 0.5 mg/kg, fentanyl 10 µg/kg, propofol 7.5 mg/kg, or dexmedetomidine 25 µg/kg) were administered 1 hour before ischemia. Creatinine levels were determined in serum, and expression of kidney injury molecule 1 and sirtuin 1, 2, 3 and 7 in kidney tissue was quantified by RT-PCR.
RESULTS: Anesthetic preconditioning with morphine, fentanyl, propofol and dexmedetomidine reduced kidney injury markers after I-R and modulated sirtuin gene expression. Opioids or dexmedetomidine administration before ischemia increased sirtuin 2 expression and correlated with improved renal function.
CONCLUSIONS: Anesthetic preconditioning is a promising strategy to prevent I-R injury associated with transplantation. Our results suggest that sirtuin 2 is involved in the protective mechanisms of some commonly used anesthetics against I-R damage.
