"CYP2C11 and CYP2C23 epoxygenases were highly expressed in interlobar renal arteries and renal cortex respectively and were co-localized with eNOS in renal endothelial cells. These results demonstrate that H2O2 is involved in the EDH-type relaxant responses of renal arteries and that CYP 2C epoxygenases are physiologically relevant endothelial sources of vasodilator H2O2 in the kidney."xsd:string
