[The role of estrogen related-receptor γ and ATP-dependent K(+) channel Kcnj1 in renal ischemia-reperfusion injury].
Objective: To investigate the correlation between estrogen related-receptorγ (ERRγ) and ATP-dependent K(+) channel Kcnj1 in renal ischemia-reperfusion injury and its possible role in regulating ischemic preconditioning. Methods: The expression of ERRγ in kidney tissues was detected by immunohistochemistry. The expressions of ERRγ and Kcnj1 in human renal tubular epithelial cells (HK-2) under hypoxia (1% O(2)) were detected by RT-PCR. ⋯ However, Kcnj1 expression in renal tissue of ERR-γ-deficient mice was stable, but ischemic preconditioning failed to interfere with renal ischemia-reperfusion injury. Conclusion: ERRγ-Kcnj1 is closely related to ischemic preconditioning and protects renal ischemia-reperfusion injury, and may be one of the regulatory factors. To explore the protective effect of the regulating pathway on ischemia reperfusion injury couldprovide a theoretical basis for the development of drug pretreatment.
