MicroRNAs (miR) are important diagnostic and treatment targets due to their different tissue expressions and their central position in the regulation of gene expressions. miR studies might pioneer emerging of new diagnostic tools and treatment goals in kidney diseases. Captopril (CAP) and telmisartan (TEL) were shown to be effective in ischemia reperfusion (IR) injury. There is not any study about the effect of TEL and CAP over miR-21-320-146a. Our aim was to study the effects of CAP and TEL over miR on renal IR model.We used 12-16 weeks-old Wistar-Albino rats that weigh 300-350 g. Rats (n, 6) were randomized into four groups (Control, IR, IR + CAP, IR + TEL). Urea, creatinine, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), super oxide dismutase (SOD), and miRs were analyzed.Urea, creatinine, TOS, OSI levels of IR + CAP, and IR + TEL groups were lower comparing to IR group. TAS and SOD levels were higher in IR group than IR + TEL group. miR-21-320-146a showed increase in renal IR injury. miR-320, 146a showed significant decrease in IR + CAP and IR + TEL groups comparing to IR group. We showed histopathological recovery and decreased apoptosis in IR + CAP and IR + T groups than IR group.We, for the first time in the literature, showed that miR-320 is increased in IR injury. miR-320 might be a novel diagnosis and treatment target in renal ischemic reperfusion injury. Also, for the first time, we showed that CAP and TEL cause functional and histopathological recovery and lower miR-146a and miR-320.
