A new combination of naringin and trimetazidine protect kidney Mitochondria dysfunction induced by renal Ischemia / Reperfusion injury in rat

Abstract

Ischemia/reperfusion (IR) injury leads to overproduction of Reactive Oxygen Species (ROS), and disrupts membrane potential that contributes to cell death. The aim of this study was to determine if naringin (NAR), trimetazidine (TMZ) or their combination, protect the kidney mitochondrial from IR injury. Forty rats were randomly allocated into five groups, harboring eight rats each: Sham, IR, NAR (100 mg/kg), TMZ (5 mg/kg) and NAR plus TMZ. Ischemia was induced by obstructing both renal pedicles for 45 min, followed by reperfusion for 4 hours. The mitochondria were isolated to examine the ROS, Malondialdehyde (MDA), Glutathione (GSH), mitochondrial membrane potential (MMP) and mitochondrial viability (MTT). Our findings indicated that IR injury resulted in excessive ROS production, increased MDA levels and decreased GSH, MMP and MMT levels. However, NAR, TMZ or their combination reversed these changes. Interestingly, a higher protection was noted with the combination of both, compared to each drug alone. We speculate that this combination demonstrates a promising process for controlling renal failure, especially with the poor clinical outcome, acquired with NAR alone. This study revealed that pretreatment their combination serves as a promising compound against oxidative stress, leading to suppression of mitochondrial stress pathway and elevation of GSH level.

INTRODUCTION

Ischemia / Reperfusion (IR) is identified as one of causes of acute renal failure (ARF), which is accompanied by mortality and morbidity, and no effective treatment has yet been known for this situation (Bonventre, 1993Bonventre JV. Mechanisms of ischemic acute renal failure. Kidney Int.1993;43(5):1160-78.; Groeneveld et al., 1991Groeneveld AB, Tran DD, van der Meulen J, Nauta JJ, Thijs LG. Acute renal failure in the medical intensive care unit: predisposing, complicating factors and outcome. Nephron. 1991;59(4):602-10.). It has been previously reported that IR occurs in clinical settings, because of kidney transplantation and hypo-perfusion, followed by circulatory resuscitation or nephrectomy, burns and surgery (Groeneveld et al., 1991Groeneveld AB, Tran DD, van der Meulen J, Nauta JJ, Thijs LG. Acute renal failure in the medical intensive care unit: predisposing, complicating factors and outcome. Nephron. 1991;59(4):602-10.; Hussein et al., 2012Hussein AA, El-Dken ZH, Barakat N, Abol-Enein H. Renal ischaemia/reperfusion injury: possible role of aquaporins. Acta Physiol. 2012;204(3):308-16.). During the ischemic period, mitochondrial membrane permeability (MMP) changes and can produce reactive oxygen species (ROS), subsequently, in the reperfusion phase the generation of ROS is exacerbated, leading to increase in MMP, and reducing mitochondrial antioxidant levels (Jassem et al., 2002Jassem W, Fuggle SV, Rela M, Koo DD, Heaton ND. The role of mitochondria in ischemia/reperfusion injury. Transplantation. 2002;73(4):493-9.; Jassem, Heaton, 2004Jassem W, Heaton ND. The role of mitochondria in ischemia/ reperfusion injury in organ transplantation. Kidney Int . 2004;66(2):514-17.). Oxidative damage can cause lipid peroxidation, DNA breakdown and could be able to damage mitochondrial proteins, which is considered as different approaches to organ injury (Bonventre, 1993Bonventre JV. Mechanisms of ischemic acute renal failure. Kidney Int.1993;43(5):1160-78.; Bonventre, Yang, 2011Bonventre JV, Yang L. Cellular pathophysiology of ischemic acute kidney injury. J Clin Invest. 2011;121(11):4210-21.). Studies have shown, mitochondrial dysfunction plays a critical role in ROS overproduction (Jassem et al., 2002Jassem W, Fuggle SV, Rela M, Koo DD, Heaton ND. The role of mitochondria in ischemia/reperfusion injury. Transplantation. 2002;73(4):493-9.; Jassem, Heaton, 2004Jassem W, Heaton ND. The role of mitochondria in ischemia/ reperfusion injury in organ transplantation. Kidney Int . 2004;66(2):514-17.). In physiological condition, mitochondrial ROS is neutralized by the mitochondrial antioxidant levels (Jassem, Heaton, 2004Jassem W, Heaton ND. The role of mitochondria in ischemia/ reperfusion injury in organ transplantation. Kidney Int . 2004;66(2):514-17.). Among the proposed mechanisms most critical one are oxidative stress, ROS overproduction and disruption of adenosine triphosphate (ATP) production (Jassem et al., 2002Jassem W, Fuggle SV, Rela M, Koo DD, Heaton ND. The role of mitochondria in ischemia/reperfusion injury. Transplantation. 2002;73(4):493-9.). There is a correlation between ROS production from mitochondrial damage and various diseases, including kidney diseases (Sureshbabu, Ryter, Choi, 2015Sureshbabu A, Ryter SW, Choi ME. Oxidative stress and autophagy: Crucial modulators of kidney injury. Redox Biol. 2015;4:208-14.), myocardial injury (Argaud et al., 2005Argaud L, Gomez L, Gateau-Roesch O, Couture-Lepetit E, Loufouat J, Robert D, et al. Trimetazidine inhibits mitochondrial permeability transition pore opening and prevents lethal ischemia-reperfusion injury. J Mol Cell Cardiol. 2005;39(6):893-9.) and neurodegenerative diseases (Rao, Carlson, Yan, 2014Rao VK, Carlson EA, Yan SS. Mitochondrial permeability transition pore is a potential drug target for neurodegeneration. Biochim Biophys Acta . 2014;1842(8):1267-72.).

The mitochondrial glutathione (GSH) concentration in the cytosol is similar to that found in the mitochondrial matrix and is identified as the first line of defense against oxidative damage to mitochondrial membranes (Lash, Putt, Matherly, 2002Lash LH, Putt DA, Matherly LH. Protection of NRK-52E cells, a rat renal proximal tubular cell line, from chemical-induced apoptosis by overexpression of a mitochondrial glutathione transporter. J Pharmacol Exp Ther . 2002;03(2):476-86.). GSH acts not only as a free radical scavenging substance, but also contributes in several other physiological processes, including cell proliferation, conservation of GSH/GSSG redox, cell signaling, and apoptosis (Mari et al., 2009Mari M, Morales A, Colell A, Garcia-Ruiz C, Fernandez- Checa JC. Mitochondrial glutathione, a key survival antioxidant. Antioxid Redox Signal. 2009;11(11):2685-700.).

Nowadays, antioxidant agents have been used to prevent organ failure in a variety of clinical settings and experimental models (Adil et al., 2016Adil M, Kandhare AD, Ghosh P, Venkata S, Raygude KS, Bodhankar SL. Ameliorative effect of naringin in acetaminophen-induced hepatic and renal toxicity in laboratory rats: role of FXR and KIM-1. Ren Fail. 2016;38(6):1007-20.; Spargias et al., 2004Spargias K, Alexopoulos E, Kyrzopoulos S, Iokovis P, Greenwood DC, Manginas A, et al. Ascorbic acid prevents contrast-mediated nephropathy in patients with renal dysfunction undergoing coronary angiography or intervention. Circulation. 2004;110(18):2837-42.). Naringin (4, 5, 7-trihydroxy flavonone 7- rhamnoglucoside) (NAR) is a substantial natural substance and a polyphenol compound mainly present in grapefruits and citrus species (Chen et al., 2016Chen R, Qi QL, Wang MT, Li QY. Therapeutic potential of naringin: an overview. Pharm Biol. 2016;54(12):3203-3210.). Among the naturally polyphenols compound, it has been established to have no side effect (Choe et al., 2001Choe SC, Kim HS, Jeong TS, Bok SH, Park YB. Naringin has an antiatherogenic effect with the inhibition of intercellular adhesion molecule-1 in hypercholesterolemic rabbits. J Cardiovasc Pharmacol. 2001;38(6):947-55.). Therefore, several studies demonstrated that NAR exhibits, free radical scavenging properties in renal toxicity (Adil et al., 2015Adil M, Kandhare AD, Visnagri A, Bodhankar SL. Naringin ameliorates sodium arsenite-induced renal and hepatic toxicity in rats: decisive role of KIM-1, Caspase-3, TGF-beta, and TNF-alpha. Ren Fail . 2015;37(8):1396-407.; Singh, Chander, Chopra, 2004Singh D, Chander V, Chopra K. Protective effect of naringin, a bioflavonoid on glycerol-induced acute renal failure in rat kidney. Toxicology. 2004;201(1-3):143-51.). It has been reported that NAR has a variety of pharmacological characteristics, such as anti-cancer, anti-mutagenic, cholesterol lowering and antioxidant effects, anti-inflammatory, and free radical scavenging effect (Rajadurai, Prince, 2007Rajadurai M, Prince PS. preventive effect of naringin on cardiac mitochondrial enzymes during isoproterenol- induced myocardial infarction in rats: a transmission electron microscopic study. J Biochem Mol Toxicol. 2007;21(6):354-61.).

Trimetazidine (TMZ) is known as an anti-ischemic agent (piperazine derivative) that has a protective effect against oxidative stress, because of antioxidant properties and can limit renal IR injury (Nadkarni et al., 2015Nadkarni GN, Konstantinidis I, Patel A, Yacoub R, Kumbala D, Patel RA, et al. Trimetazidine decreases risk of contrast- induced nephropathy in patients with chronic kidney disease: a meta-analysis of randomized controlled trials. J Cardiovasc Pharmacol Ther. 2015;20(6):539-46.; Sulikowski et al., 2008Sulikowski T, Domanski L, Ciechanowski K, Adler G, Pawlik A, Safranow K, et al. Effect of trimetazidine on xanthine oxidoreductase expression in rat kidney with ischemia-- reperfusion injury. Arch Med Res. 2008;39(4):459-62.). A recent experimental model study indicated that TMZ can be considered as mPTP (mitochondrial permeability transition pore) inhibitor and could be cardio protective in cardiac IR injury (Argaud et al., 2005Argaud L, Gomez L, Gateau-Roesch O, Couture-Lepetit E, Loufouat J, Robert D, et al. Trimetazidine inhibits mitochondrial permeability transition pore opening and prevents lethal ischemia-reperfusion injury. J Mol Cell Cardiol. 2005;39(6):893-9.). The present study highlighted whether the combination of NAR and TMZ could protect kidney mitochondria damage, induced by renal IR injury in a rat model.

MATERIAL AND METHODS

Animals

Forty male Sprague-Dawley rats, weighing 200- 250 g, were used and kept in polycarbonate cages at 22 °C, with 50% humidity for 12 hours of light and 12 hours of darkness in an optical cycle. Sufficient water and pellet diet were provided for the rats. Animals are purchased from the Laboratory Animal Reproductive Center of Ahvaz Jundishapur University of Medical Sciences. The experimental protocol was approved by the Ethics Committee of Ahvaz Jundishapur University of Medical Sciences.

Chemicals

TMZ, NAR, urethane, rhodamine 123, 4-(2-Hydroxyethyl)-1-piperazineethanesulfonic acid) (HEPES), mannitol, ethylene glycol tetra-acetic acid (EGTA), bovine serum albumin (BSA), 2,7- dichlorofluorescein diacetate (DCFH-DA), 3,4 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and Coomassie Brilliant Blue, were purchased from Sigma-Aldrich (St Louis, Missouri, USA), and sucrose and dimethyl sulfoxide (DMSO) were obtained from Merck (Darmstadt, Germany).

Experimental design

Forty rats were randomly allocated into five groups of eight rats each. Group I: Sham- operated, all surgical procedures are performed on these animals, except pedicle clamp. Group II: renal IR injury, the animals were given normal saline for 7 days, intraperitoneally, then, surgery and the pedicle clamp technique were done. Group III: the animals received NAR 100 mg/ kg, intraperitoneally for 7 days before IR and pedicle clamp method were performed (Gaur, Aggarwal, Kumar, 2009Gaur V, Aggarwal A, Kumar A. Protective effect of naringin against ischemic reperfusion cerebral injury: possible neurobehavioral, biochemical and cellular alterations in rat brain. Eur J Pharmacol. 2009;616(1-3):147-54.). Group IV: the animals received TMZ 5 mg/kg, intravenously, five minutes before onset of reperfusion (Cau et al., 2008Cau J, Favreau F, Tillement JP, Lerman LO, Hauet T, Goujon JM. Trimetazidine reduces early and long-term effects of experimental renal warm ischemia: a dose effect study. J Vasc Surg. 2008;47(4):852-60.). Group V: rats received TMZ 5 mg/ kg, five minutes before beginning of reperfusion plus NAR 100 mg/kg for 7 days before IR. The concentrations of TMZ and NAR were selected in accordance with previous studies and a pilot study (Cau et al., 2008Cau J, Favreau F, Tillement JP, Lerman LO, Hauet T, Goujon JM. Trimetazidine reduces early and long-term effects of experimental renal warm ischemia: a dose effect study. J Vasc Surg. 2008;47(4):852-60.; Gaur, Aggarwal, Kumar, 2009Gaur V, Aggarwal A, Kumar A. Protective effect of naringin against ischemic reperfusion cerebral injury: possible neurobehavioral, biochemical and cellular alterations in rat brain. Eur J Pharmacol. 2009;616(1-3):147-54.).

Induction of IR injury

At the day of surgery, animals were anesthetized by urethane at a dose of 1.7 gr/kg, intraperitoneally (Maleki, Nematbakhsh, 2016Maleki M, Nematbakhsh M. Renal blood flow response to angiotensin 1-7 versus hypertonic sodium chloride 7.5% administration after acute hemorrhagic shock in rats. Int J Vasc Med. 2016;2016:6562017.). Appropriate anesthetic level was maintained during the test by anesthetic drugs. Animal body temperature was controlled through thermostatic blankets at 37 o C (Harvard Apparatus, UK). Tracheostomy was performed to ensure airway openness and spontaneous breathing. Midline laparotomy was preformed to expose both of the kidneys. Bilateral ischemia was created by obstructing both renal pedicles, using non-traumatic clamps for 45 min, then, clamps were removed and reperfusion was followed for 4 hours (Nesic et al., 2006Nesic Z, Todorovic Z, Stojanovic R, Basta-Jovanovic G, Radojevic-Skodric S, Velickovic R, et al. Single-dose intravenous simvastatin treatment attenuates renal injury in an experimental model of ischemia-reperfusion in the rat. J Pharmacol Sci. 2006;102(4):413-17.).

Isolation of kidney mitochondria

Ultimately, after the reperfusion, the kidneys were immediately dissected and placed on the ice plate, then minced with a scissor. Purification buffer solution, containing mannitol (200 mM), HEPES (10 mM), EGTA (1mM), sucrose (70 mM) and 0.1% BSA were added to the kidney and homogenized by homogenizer at 1000 g for 10 minutes. Homogeneous tissue was centrifuged at 4°C, several times at different times, according to the protocol (Hosseini et al., 2014Hosseini MJ, Shaki F, Ghazi-Khansari M, Pourahmad J. Toxicity of copper on isolated liver mitochondria: impairment at complexes I, II, and IV leads to increased ROS production. Cell Biochem Biophys. 2014;70(1):367-81.). All stages of the isolation and purification of mitochondria were performed on ice. All factors were measured on mitochondrial suspension (0.5 mg protein per ml). Each experiment was repeated 3 times for each rat. Mitochondrial protein level was examined, using the Bradford method (Bradford, 1976Bradford MM. A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding. Anal Biochem.1976;72(1):248-54.).

Determination of mitochondrial membrane potential

The mitochondrial membrane potential (ΔΨm; MMP) collapse was determined, using a cationic fluorescent probe, rhodamine 123, accumulated in the mitochondria by simplifying diffusion and electric gradient force. Healthier mitochondria would collect more rhodamine 123 in their matrices. Aqueous rhodamine solution has an emission peak at 535 nm, whereas matrix and under stacks’ rhodamine experiences a fluorescence quenching. When damage occurs, the ratio of red-to-green fluorescence is diminished, compared to the healthy mitochondria. The fluorescence intensity was determined, using a spectrofluorometeric detector (LS50B Perkin Elmer, Waltham, Massachusetts, Ex = 490 nm, Em = 535 nm) (Baracca et al., 2003Baracca A, Sgarbi G, Solaini G, Lenaz G. Rhodamine 123 as a probe of mitochondrial membrane potential: evaluation of proton flux through F(0) during ATP synthesis. Biochim Biophys Acta. 2003;1606(1-3):137-46.). Our data were expressed as the percentage of mitochondrial membrane potential collapse (%ΔΨm), among groups.

Mitochondrial ROS assay

To measu re the amou nt of ROS, 2 ′, 7′-Dichlorodihydrofluorescein diacetate (DCFH-DA) was used. DCFH-DA penetrates into mitochondria and hydrolyzes to non-fluorescent DCFH, accumulating in the mitochondria. Then, reaction with ROS, it is oxidized to form highly fluorescent 2, 7-dichlorofluorescein. DCFH- DA was added to the mitochondria suspension (0.5 mg/ mL) (Zhang et al., 2008Zhang F, Xu Z, Gao J, Xu B, Deng Y. In vitro effect of manganese chloride exposure on energy metabolism and oxidative damage of mitochondria isolated from rat brain. Environ Toxicol Pharmacol. 2008;26(2):232-6.). The amount of ROS generation was determined using a spectrofluorometeric detector (UV-1650PC SHIMADZU, Kyoto, Japan), based on the fluorescence intensity unit. The excitation and emission wavelengths are 500 nm and 520 nm, respectively.

Mitochondrial viability (MTT assay)

This colorimetric method is a quantitative measure for viability, in which the yellow salt of tetrazolium is converted to formazan by the mitochondrial dehydrogenase enzyme. MTT solution was added to 1 ml of mitochondrial suspension (0.5 mg/ml), following an incubation period (Mosmann, 1983Mosmann T. Rapid colorimetric assay for cellular growth and survival: application to proliferation and cytotoxicity assays. J Immunol Methods. 1983;65(1-2):55-63.). Then, 200 μl of DMSO was added and the absorbance was determined at 570 nm wavelength, using a spectrophotometer (UV-1650PC Shimadzu).

Measurement of mitochondria Malondialdehyde (MDA) content

First, 250 μl of 70% trichloroacetic acid was added to the mitochondrial suspension (0.5 mg/mL), and centrifuged at 3000 g for 15 minutes. Then, 0.8% tiobarbituric acid was added to the supernatant, and stood in boiling water for 30 minutes. The absorbance was determined at 532 nm wavelength, using a spectrophotometer (Zhang et al., 2008Zhang F, Xu Z, Gao J, Xu B, Deng Y. In vitro effect of manganese chloride exposure on energy metabolism and oxidative damage of mitochondria isolated from rat brain. Environ Toxicol Pharmacol. 2008;26(2):232-6.).

Measurement of mitochondrial GSH content

The glutathione mitochondrial content was measured by the formation of yellow color, because of the reaction of glutathione with the indicator of Ellman (DTNB). In summary, mitochondrial suspension was added to 2 ml of Ellman’s reagent and the absorbance was read at 412 nm, using a spectrophotometer (Sadegh, Schreck, 2003Sadegh C, Schreck RP. The spectroscopic determination of aqueous sulfite using Ellman’s reagent. MURJ. 2003;8:39-43.).

Statistical analysis

Data were analyzed, using SPSS, version 16. Statistical significance was determined using the one- way ANOVA with the Tukey’s post hoc test. Statistical significance was considered as p< 0.05.

RESULTS

Effect of NAR, TMZ and their combination on MTT assay

MTT as mitochondrial viability assay was determined, concerning the activity of succinate dehydrogenase (complex II). As demonstrated in Figure 1, renal IR injury could cause a remarkable decrease in complex ІІ activity (p<0.001), compared to the sham group. However, the results of NAR, TMZ or their combination in pretreatment, indicated a significant increase in MTT level, compared to renal IR injury rats (p< 0.05, p< 0.001 and p< 0.001, respectively) and co- administration revealed a significant increase in MTT level, compared to the NAR alone (p< 0.01).

Effect of NAR, TMZ and their combination on MMP

As demonstrated in Figure 2, renal IR injury in kidney led to a significant increase in mitochondrial membrane damage (p< 0.05). However, the administration of NAR and TMZ or their combination, reduced the fluorescence intensity, indicating mitochondrial protection. The effects of these drugs result in a significant reduction of damage to MMP (p< 0.05, p< 0.01 and p< 0.001, respectively).

Effect of NAR, TMZ and their combination on mitochondria ROS generation

ROS was examined throughout DCFH-DA oxidation. The relative DCF fluorescence intensity demonstrates different ROS concentrations in different groups. Rat’s kidney mitochondria (0.5 mg/ml) were isolated, purified, and incubated in buffer, containing sucrose, mannitol, EGTA and HEPES (pH: 7.4) for 1h. As shown in Figure 3, renal IR injury stimulated ROS generation more significantly, compared to the sham group (p< 0.001). Administration of NAR, TMZ or their combination significantly decreased mitochondrial ROS generation, compared to the untreated IR injury group (p< 0.01, p< 0.001, p< 0.001). Moreover, co-administration of NAR and TMZ results in a significant reduction of ROS production, compared to the NAR alone (p< 0.05).

Effect of NAR, TMZ and their combination on the mitochondria lipid peroxidation

As shown in Figure 4, lipid peroxidation was determined by the extent of MDA creation, during an acid heating reaction. In comparison to the sham group, MDA increased remarkably in the IR injury group (p< 0.001). Whereas, TMZ and their combined administration significantly reduced the MDA level, compared to the IR injury group (p< 0.05 and p< 0.001, respectively). Pretreatment with a combination of NAR and TMZ significantly reduced the MDA level, compared to the NAR alone (p< 0.05).

Effect of NAR, TMZ and their combination on mitochondria GSH

As shown in Figure 5, a remarkable decrease in mitochondrial GSH levels was seen in the rat IR injury, compared with those in the sham group (p< 0.001). Although, NAR and TMZ alone increased the glutathione content, but this increase was not significant, while their combination improved the depletion of mitochondrial GSH, compared to the renal IR injury group (p< 0.001). Meanwhile, co-administration of NAR and TMZ significantly increased the mitochondrial GSH, compared to either NAR or TMZ alone (p< 0.001). Based on these results, it is recommended that co-administration may provide a crucial role in the elimination of ROS through mitochondrial GSH preservation via GSH synthesis.

DISCUSSION

The present data demonstrated that renal IR injury induced kidney mitochondrial oxidative stress via increasing MDA and ROS, and reducing GSH levels. Hence, the findings regarding NAR, TMZ or co-administration of both demonstrated protective effects against oxidative stress induced by IR in isolated kidney mitochondria.

The available evidence suggests that renal IR injury is associated with cellular and molecular events, causing injury to kidney tubular cells (Chatterjee et al., 2001Chatterjee PK, Brown PA, Cuzzocrea S, Zacharowski K, Stewart KN, Mota-Filipe H, et al. Calpain inhibitor-1 reduces renal ischemia/reperfusion injury in the rat. Kidney Int . 2001;59(6):2073-83.; Lieberthal, Levine, 1996Lieberthal W, Levine JS. Mechanisms of apoptosis and its potential role in renal tubular epithelial cell injury. Am J Physiol. 1996;271(3 Pt 2):F477-88.). Due to its importance, it necessitates to discover new drugs that are able to protect the kidney from IR injury.

Growing evidence suggest that oxidative stress as a result of ROS generation by renal IR injury, is one of process involved in cell damage and renal dysfunction (Serviddio et al., 2008Serviddio G, Romano AD, Gesualdo L, Tamborra R, Di Palma AM, Rollo T, et al. Post conditioning is an effective strategy to reduce renal ischaemia/reperfusion injury. Nephrol Dial Transplant. 2008;23(5):1504-12.). Mitochondrial ROS is increased under IR injury, hypoxia, toxicity drug and pathologic situation (Ribas, Garcia-Ruiz, Fernandez- Checa, 2014Ribas V, García-Ruiz C, Fernández-Checa JC. Glutathione and mitochondria. Front Pharmacol. 2014;5:151.). The mitochondria damage associated with overproduction of ROS, has been identified to play a major role in oxidative stress and cell death (Pieczenik, Neustadt, 2007Pieczenik SR, Neustadt J. Mitochondrial dysfunction and molecular pathways of disease. Exp Mol Pathol. 2007;83(1):84-92.). Indeed, during IR injury, mitochondria is exposed to alterations that result in diminished ATP generation and overproduction of ROS (Jassem et al., 2002Jassem W, Fuggle SV, Rela M, Koo DD, Heaton ND. The role of mitochondria in ischemia/reperfusion injury. Transplantation. 2002;73(4):493-9.). Reperfusion is a necessary stage of ischemic tissue and is associated with the opening of mPTP on the inner mitochondrial membrane, triggering a series of mitochondrial events (Kovacs et al., 2010Kovacs A, Moricz K, Albert M, Benedek A, Harsing LG, Szenasi G. Decreased vasoconstrictor responses in remote cerebral arteries after focal brain ischemia and reperfusion in the rat, in vitro. Eur J Pharmacol . 2010;644(1-3):154-9.). Opening of mPTP prior to reperfusion time leads to collapse of MMP, after excess production of ROS (Jassem et al., 2002Jassem W, Fuggle SV, Rela M, Koo DD, Heaton ND. The role of mitochondria in ischemia/reperfusion injury. Transplantation. 2002;73(4):493-9.). Over generation of ROS led to membrane damage, mPTP opening, and mitochondrial potential disruption (Jassem et al., 2002Jassem W, Fuggle SV, Rela M, Koo DD, Heaton ND. The role of mitochondria in ischemia/reperfusion injury. Transplantation. 2002;73(4):493-9.). These results were parallel to what was obtained for ROS generation with IR injury, showing the greatest damage. In vitro study in renal proximal cell demonstrated that hypoxia/reoxygenation injury caused mitochondrial stress and antioxidant treatment could reverse this change (Yu et al., 2013Yu W, Sheng M, Xu R, Yu J, Cui K, Tong J, et al. Berberine protects human renal proximal tubular cells from hypoxia/ reoxygenation injury via inhibiting endoplasmic reticulum and mitochondrial stress pathways. J Transl Med. 2013;11:24. doi:10.1186/1479-5876-11-24
https://doi.org/10.1186/1479-5876-11-24...
). The current study showed that renal IR was able to enhance ROS generation in kidney mitochondria. Several studies have reported the beneficial effects of antioxidant enzyme due to the free-radical scavenging properties against AKI-induced IR injury (Hosseini et al., 2010Hosseini F, Naseri MK, Badavi M, Ghaffari MA, Shahbazian H, Rashidi I, et al. Effect of beta carotene on lipid peroxidation and antioxidant status following renal ischemia/reperfusion injury in rat. Scand J Clin Lab Invest. 2010;70(4):259-63.; Lee, Son, Kim, 2006Lee JI, Son HY, Kim MC. Attenuation of ischemia- reperfusion injury by ascorbic acid in the canine renal transplantation. J Vet Sci. 2006;7(4):375-9.). The previous study has shown that NAR could ameliorate mitochondrial dysfunction by reducing oxidative stress (Sachdeva, Kuhad, Chopra, 2014Sachdeva AK, Kuhad A, Chopra K. Naringin ameliorates memory deficits in experimental paradigm of Alzheimer’s disease by attenuating mitochondrial dysfunction. Pharmacol Biochem Behav. 2014;127:101-10.). Experimental study demonstrated that administration of TMZ before ischemia could prevent the reduction of ATP production and disruption of mitochondrial membrane potential, indicating cytoprotective activity against the undesirable effect of IR injury (Elimadi et al., 1998Elimadi A, Settaf A, Morin D, Sapena R, Lamchouri F, Cherrah Y. Trimetazidine counteracts the hepatic injury associated with ischemia-reperfusion by preserving mitochondrial function. J Pharmacol Exp Ther. 1998;286(1):23-28.).

MDA, a product of polyunsaturated fatty acid peroxidation due to ROS overproduction, is applied as an index of oxidative damage in renal IR injury and multiple diseases (Adil et al., 2016Adil M, Kandhare AD, Ghosh P, Venkata S, Raygude KS, Bodhankar SL. Ameliorative effect of naringin in acetaminophen-induced hepatic and renal toxicity in laboratory rats: role of FXR and KIM-1. Ren Fail. 2016;38(6):1007-20.; Najafi et al., 2015Najafi H, Changizi Ashtiyani S, Sayedzadeh SA, Mohamadi Yarijani Z, Fakhri S. Therapeutic effects of curcumin on the functional disturbances and oxidative stress induced by renal ischemia/reperfusion in rats. Avicenna J Phytomed. 2015;5(6):576-86.; Visnagri, Kandhare, Bodhankar, 2015Visnagri A, Kandhare AD, Bodhankar SL. Renoprotective effect of berberine via intonation on apoptosis and mitochondrial-dependent pathway in renal ischemia reperfusion-induced mutilation. Ren Fail . 2015;37(3):482-93.). ROS attack the polyunsaturated fatty acid of the cell membrane and cause peroxidation of the membrane lipids, resulting in the loss of membrane integrity and membrane permeability (Chen, Yu, 1994Chen JJ, Yu BP. Alterations in mitochondrial membrane fluidity by lipid peroxidation products. Free Radic Biol Med.1994;17(5):411-8.). According to the results of the current study, IR injury result in increasing of mitochondria MDA content, indicating an elevated lipid peroxidation could be related to overproduction of ROS by renal IR. There is evidence that the structure of lipophilic flavonoids leads to interaction with lipid membranes and increases its concentration in the lipid bilayer, suggesting more effective action in scavenging free oxygen radical (Wilcox, Borradaile, Huff, 1999Wilcox LJ, Borradaile NM, Huff MW. Antiatherogenic properties of naringenin, a citrus flavonoid. Cardiovasc Drug Rev. 1999;17(2):160-78.). Evidence from experimental study implicated that NAR produced a significant reduction in MDA level in nephrotoxicity, was inconsistent with the results of the current study (Adil et al., 2015Adil M, Kandhare AD, Visnagri A, Bodhankar SL. Naringin ameliorates sodium arsenite-induced renal and hepatic toxicity in rats: decisive role of KIM-1, Caspase-3, TGF-beta, and TNF-alpha. Ren Fail . 2015;37(8):1396-407.). In vivo study indicated that TMZ leads to significant decline in lipid peroxidation in renal IR injury (Grekas et al., 1996Grekas D, Dioudis C, Papageorgiou G, Iliadis S, Zilidis C, Alivanis P, et al. Lipid peroxidation after acute renal ischemia and reperfusion in rats: the effect of trimetazidine. Ren Fail .1996;18(4):545-52.). Interestingly, NAR or TMZ pretreatment caused improvement in lipid peroxidation, however, the best result acquired with co-administration of both.

GSH as a non-enzymatic antioxidant is synthesized by cells and can provide major antioxidant activities against ROS, by its sulfhydryl groups, leading to cellular defense (Ribas, Garcia-Ruiz, Fernandez-Checa, 2014Ribas V, García-Ruiz C, Fernández-Checa JC. Glutathione and mitochondria. Front Pharmacol. 2014;5:151.). According to previous studies, the alterations of glutathione metabolism are associated with renal IR injury and different diseases (Mari et al., 2009Mari M, Morales A, Colell A, Garcia-Ruiz C, Fernandez- Checa JC. Mitochondrial glutathione, a key survival antioxidant. Antioxid Redox Signal. 2009;11(11):2685-700.; Zhang et al., 2008Zhang F, Xu Z, Gao J, Xu B, Deng Y. In vitro effect of manganese chloride exposure on energy metabolism and oxidative damage of mitochondria isolated from rat brain. Environ Toxicol Pharmacol. 2008;26(2):232-6.). In renal proximal tubular cells, it has been reported that the increased content of glutathione has a protecting role against oxidants (Lash, Putt, Matherly, 2002Lash LH, Putt DA, Matherly LH. Protection of NRK-52E cells, a rat renal proximal tubular cell line, from chemical-induced apoptosis by overexpression of a mitochondrial glutathione transporter. J Pharmacol Exp Ther . 2002;03(2):476-86.). The experimental study showed that renal IR injury results in oxidative stress and decrease of GSH level in kidney tissue, but the administration of resveratrol prevents the kidney injury through reducing MDA levels and increasing GSH levels (Baltaci et al., 2019Baltaci AK, Gokbudak H, Baltaci SB, Mogulkoc R, Avunduk MC. The effects of resveratrol administration on lipid oxidation in experimental renal ischemia-reperfusion injury in rats. Biotech Histochem. 2019;94(8):592-599.).

Based on our data, renal IR injury results in a significant reduction in glutathione level, indicating a decrease in antioxidant capacity, which leads to impairment of antioxidant defense against oxidative stress. The reduction of glutathione content may be related to overproduction of ROS by renal IR injury, further ROS generation can cause oxidization of glutathione pool, subsequently, result in the formation of protein dithiols, accompanied by antioxidant system deficiency (Ribas, Garcia-Ruiz, Fernandez-Checa, 2014Ribas V, García-Ruiz C, Fernández-Checa JC. Glutathione and mitochondria. Front Pharmacol. 2014;5:151.). Administration of antioxidants has been reported to inhibit mitochondria dysfunction through enhancing antioxidant capacity (Ranjbar et al., 2018Ranjbar A, Kheiripour N, Ghasemi H, Seif Rabiei MA, Dadras F, Khoshjou F. Antioxidative effects of tempol on mitochondrial dysfunction in diabetic nephropathy. Iran J Kidney Dis. 2018;12(2):84-90.). In this regard, in vivo study showed that NAR caused an increase in antioxidant enzymes’ activity of the kidney tissue, including superoxide dismutase, catalase and glutathione after renal IR injury model, suggesting NAR’s ability to decrease IR induced oxidative damage in the rat kidney (Singh, Chopra, 2004Singh D, Chopra K. The effect of naringin, a bioflavonoid on ischemia-reperfusion induced renal injury in rats. Pharmacol Res. 2004;50(2):187-93.). In experimental and human study, TMZ’s ability to increase the glutathione level has been reported (Bayram et al., 2005Bayram E, Atalay C, Kocaturk H, Yucel O. Effects of trimetazidine on lipid peroxidation, antioxidant enzyme activities and plasma brain natriuretic peptide levels in patients with chronic corpulmonale. J Int Med Res. 2005;33(6):612-9.; Suzer et al., 2000Suzer T, Coskun E, Demir S, Tahta K. Lipid peroxidation and glutathione levels after cortical injection of ferric chloride in rats: effect of trimetazidine and deferoxamine. Res Exp Med. 2000;199(4):223-9.).

As shown in previous studies, consumption of NAR and TMZ by increasing antioxidant activity and preventing the opening of mPTP (Argaud et al., 2005Argaud L, Gomez L, Gateau-Roesch O, Couture-Lepetit E, Loufouat J, Robert D, et al. Trimetazidine inhibits mitochondrial permeability transition pore opening and prevents lethal ischemia-reperfusion injury. J Mol Cell Cardiol. 2005;39(6):893-9.), respectively, have shown to be beneficial against oxidative damage, and their co-administration were more effective than administration of each alone. Recently, we reported that NAR and TMZ or their combination had a renoprotective effect through increasing antioxidant capacity and inhibition of apoptosis signaling that result in improvement of kidney function (Amini et al., 2019aAmini N, Sarkaki A, Dianat M, Mard SA, Ahangarpour A, Badavi M. The renoprotective effects of naringin and trimetazidine on renal ischemia/reperfusion injury in rats through inhibition of apoptosis and down regulation of micoRNA-10a. Biomed Pharmacother. 2019a;112:108568. doi: 10.1016/j.biopha.2019.01.029.
https://doi.org/10.1016/j.biopha.2019.01...
). In another study indicated that NAR and TMZ or their combination inhibit myocardial injury in renal IR injury model via enhancing the Nrf-2 expression (Amini et al., 2019bAmini N, Sarkaki A, Dianat M, Mard SA, Ahangarpour A, Badavi M. Protective effects of naringin and trimetazidine on remote effect of acute renal injury on oxidative stress and myocardial injury through Nrf-2 regulation. Pharmacol Rep. 2019b;71(6):1059-1066.).

CONCLUSION

In summary, NAR or TMZ could significantly inhibit IR-induced oxidative stress, therefore preserving the kidney mitochondria. Higher safeguarding was proposed by a combination of TMZ and NAR. Consequently, we speculate that this mixture demonstrates a promising process during AKI, especially one caused by IR injury, suggesting a renoprotective effect against oxidative stress, induced by IR injury.
