Inhibition of PLK3 Attenuates Tubular Epithelial Cell Apoptosis after Renal Ischemia-Reperfusion Injury by Blocking the ATM/P53-Mediated DNA Damage Response.

We demonstrate for the first time that PLK3 is involved in oxidative stress-induced DNA damage and TEC apoptosis in renal I/R injury. Inhibition of PLK3 attenuates TEC apoptosis after I/R injury by blocking the ATM/P53-mediated DDR. Therefore, PLK3 may serve as a potential therapeutic target for ischemic AKI.
