Mitochondrial NADP(+)-dependent isocitrate dehydrogenase (IDH2) catalyzes the
oxidative decarboxylation of isocitrate to ?-ketoglutarate, synthesizing NADPH,
which is essential for mitochondrial redox balance. Ischemia-reperfusion (I/R) is
one of most common causes of AKI. I/R disrupts the mitochondrial redox balance,
resulting in oxidative damage to mitochondria and cells. Here, we investigated
the role of IDH2 in I/R-induced AKI. I/R injury in mice led to the inactivation
of IDH2 in kidney tubule cells. Idh2 gene deletion exacerbated the I/R-induced
increase in plasma creatinine and BUN levels and the histologic evidence of
tubule injury, and augmented the reduction of NADPH levels and the increase in
oxidative stress observed in the kidney after I/R. Furthermore, Idh2 gene
deletion exacerbated I/R-induced mitochondrial dysfunction and morphologic
fragmentation, resulting in severe apoptosis in kidney tubule cells. In cultured
mouse kidney proximal tubule cells, Idh2 gene downregulation enhanced the
mitochondrial damage and apoptosis induced by treatment with hydrogen peroxide.
This study demonstrates that Idh2 gene deletion exacerbates mitochondrial damage
and tubular cell death via increased oxidative stress, suggesting that IDH2 is an
important mitochondrial antioxidant enzyme that protects cells from I/R insult.
