Abstract

The rising incidence and complications of diabetes constitutes a major public health issue. The mortality rate of diabetes‑induced myocardial ischemia/reperfusion (I/R) injury is significantly elevated. Resveratrol (RSV) is a naturally occurring polyphenol considered to be a potent cardioprotective compound. The aim of the present study was to explore the function and molecular mechanism of RSV on diabetes‑induced myocardial I/R injury. Left anterior descending coronary artery ligation was performed to stimulate myocardial I/R injury in streptozotocin‑induced diabetic rats. Heart electrical activity was monitored through an electrocardiogram to confirm successful models. The myocardial infarct volume was detected via 2,3,5‑triphenyltetrazolium chloride staining. Western blotting was employed to examine the levels of autophagy markers. It was found that the injection of RSV mitigated the ischemia‑ or I/R injury‑induced myocardial damage on hemodynamic function and infarct size, but the autophagy inhibitor 3‑methyladenine significantly blocked the function of RSV. Furthermore, the application of RSV significantly enhanced the expression of Beclin‑1 and LC‑3II but inhibited the serum levels of tumor necrosis factor‑α and interleukin‑6. These findings revealed an alleviating effect of RSV on diabetes‑induced myocardial I/R injury and provided new evidence for the successful application of RSV on the diabetic myocardium.

Introduction

Economic growth and improvement of living standards has led to an increase in the prevalence of diabetes (1). Coronary artery disease causing myocardial infarction is one of the main complications associated with diabetes (2). The mortality rate of diabetic patients following myocardial infarction is significantly increased, when compared with nondiabetic patients (3). Previous studies showed some key mechanisms involved in the sensitivity of the diabetic heart to myocardial infarction, such as extracellular signal regulated kinase (ERK)1/2 signaling (4), inflammatory (5) and phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT)/glycogen synthase kinase (GSK)-3β (6). Hyperglycemia is the major characteristic of diabetes, which causes reactive oxygen species overproduction and exacerbates myocardial infarction (7). Therefore, excessive autophagy is a major mechanism of myocardial ischemia reperfusion injury in diabetes (8). In ischemic patients, reperfusion to the ischemic heart mitigates the mortality rate (9); however, reperfusion also causes further myocardial dysfunction (10). It is therefore urgent to explore effective drugs against diabetic myocardial ischemia/reperfusion (I/R) injury.

Resveratrol (RVS), otherwise known as 3,4′,5-trihydroxy- transstilbene, a polyphenolic compound present in grapes, wines, peanuts and several other fruits and vegetables, has been associated with increased longevity and shown to have a positive effect in the treatment of cancer and cardiovascular disease (11). The targets of RSV include various pathways and molecules, such as sirtuins, FOXOs, and autophagy and inflammatory cytokines (12). RSV has been shown to protect against cerebral I/R injury by inhibiting NACHT, LRR and PYD domains-containing protein 3 (NLRP3) inflammasome activation, revealing the relationship between RSV and inflammatory response (13). Autophagy is a self-clearing process that removes dying or unwanted cells and is accompanied by the activation of autophagy markers Beclin 1 and light chain 3-II (LC3-II) (14). It has been reported that autophagy significantly contributes to the degree of myocardial I/R injury (15), suggesting that therapeutic manipulation of autophagy in the myocardium may benefit post-infarction cardiac healing and remodeling. Previous studies have shown that RSV reduces the severity of myocardial I/R injury by inducing autophagy (16,17). Therefore, RSV has been proposed as an effective therapy for the prevention of myocardial injury (18). It has also been reported that RSV alleviates myocardial dysfunction in diabetes and can serve as a potent pharmacological agent in reducing diabetic-induced I/R injury (3). However, its molecular mechanism remains unclear.

In the present study, the diabetic rat model was constructed through a high-fat diet combined with a streptozotocin (STZ) injection. Diabetic rats were subjected to 30 min of ischemia and 2 h of reperfusion to stimulate diabetic-induced myocardial I/R injury. It was found that the injection of RSV mitigated the ischemia- or I/R injury-induced myocardial damage on hemodynamic function and infarct size, but the autophagy inhibitor 3-methyladenine (3-MA) significantly blocked the function of RSV. Furthermore, the application of RSV significantly enhanced the expression of Beclin-1 and LC-3II but blocked the serum levels of cytokines tumor necrosis factor-α (TNF)-α and interleukin (IL)-6. In addition, the application of 3-MA suppressed the function of RSV. In conclusion, RSV alleviates I/R injury of the diabetic myocardium via inducing the expression of autophagy markers Beclin-1 and LC-3II and inhibiting expression of TNF-α and IL-6. These findings revealed an alleviating effect of RSV on diabetic-induced myocardial I/R injury, as well as its molecular basis, providing a novel strategy for diabetic myocardial I/R injury therapy.

Materials and methods

Animals and grouping

A total of 100 male Sprague-Dawley rats [Certificate no. SCXK(Zhe) 2013-0003] aged 6–8 weeks and weighing 200±20 g were purchased from the Experimental Animal Center of Zhejiang Province (Taizhou, Zhejiang, China). Rats were housed at 24±1°C with 40–50% humidity in a clean environment kept to a 12-h light/dark cycle. All animals had unlimited access to food and water. All experimental procedures were approved by the Experimental Animal Ethics Committee of Municipal Hospital of Taizhou. Rats were given a high-fat diet (20% sugar, 10% lard, 10% egg yolk powder, 2% cholesterol and 58% common chow). After 2 months, rats were intraperitoneally injected with STZ (30 mg/kg; Enzo Life Sciences, Inc.) dissolved in 0.1 mM citrate buffer (pH 4.5) according to a previous study (19). The fasting blood glucose (based on tail vein samples) was detected once a week for 4 weeks. Rats with a fasting blood glucose of ≥16.7 mM were selected as diabetic animals for follow-up experiments. Diabetic rats were randomly divided into four groups (n=20 per group), the Control, Model, RSV (Merck KGaA) and 3-MA groups. Diabetic rats in the RSV group were intragastrically administered RSV (10 mg/kg/d). Rats in the 3-MA group were intravenously administered 3-MA (15 mg/kg/d), based on the RSV injection. The Control and Model groups were injected with the same amount of physiological saline.

Animal model of myocardial I/R

Rats were anesthetized with 10% chloral hydrate (300 mg/kg) and exhibited no signs of peritonitis. A thoracotomy was performed exposing the heart. The left anterior descending (LAD) coronary artery was ligated to stimulate myocardial infarction for 30 min. Electrocardiogram (ECG) ST Segment elevation signified a successful infarction. After 30 min, the ligation was removed to restore blood flow for an additional 2 h, to stimulate reperfusion. Rats in the Model, RSV and 3-MA groups were treated according to the above procedure, and the control group underwent a sham surgery.

Measurement of hemodynamic function of the heart

Hemodynamic function was assessed prior to modeling (baseline), during trachea cannula (before ischemia) and during ischemia and I/R. The left ventricular systolic pressure (LVSP) and time derivatives of the pressure change were measured during contraction (+dP/dt) and relaxation (-dP/dt) using a polygraph, as previously described (16). A MedLab bio-signal system (Nanjing Medease Science and Technology Co., Ltd.) was used to monitor electrical activity in the heart through an ECG throughout the experiment.

Measurement of myocardial infarct size

A total of six rats in each group were randomly selected for the measurement of myocardial infarct size. The left ventricle was rapidly excised from the anesthetized rat, weighed and cut into 1–2 mm thick sections. Viable tissues were stained in red with 2% 2,3,5-triphenyltetrazolium chloride (TTC) for 20 min at 37°C. Images were captured of the stained sections and the pale-appearing infarct area was calculated using Image Pro Plus 4.5 software (Media Cybernetics, Inc.). The infarct ratio (%) was calculated by dividing the infarct volume by the total volume of the sections.

Determination of the content of TNF-a and IL-6

A total of 200 µl of blood were collected from the tails veins. After centrifugation at 4,000 × g for 8 min at 4°C, sera were collected for follow-up experiments. Serum levels of TNF-α (cat. no. JM-01587R1) and IL-6 (cat. no. JM-01597R1) were assessed with enzyme-linked immunosorbent assay (ELISA) kits (Jingmei Biological Technology, Co., Ltd.).

Western blotting

Isolated rat cardiomyocytes were homogenized into pieces for protein extraction. Proteins were extracted using RIPA buffer (Sigma-Aldrich; Merck KGa) supplemented with 1 mM PMSF (Sigma-Aldrich; Merck KGaA). The concentration was determined with bicinchoninic acid assay kit (Pierce; Thermo Fisher Scientific, Inc.). The same amount of protein (10 µg/lane) was separated by 12% SDS-PAGE using a constant voltage of 80 V for 120 min. The proteins were transferred into polyvinylidene fluoride membrane (EMD Millipore). The membrane was blocked with 5% non-fat milk in Tris-buffered saline (TBS) for 1 h at room temperature. After the blockage, the membrane was incubated with the primary antibodies (all Abcam), including rabbit monoclonal anti-PI3Kγ (ab32089; 1:1,000), anti-Beclin 1 (ab207612; 1:2,000), anti-LC-3B (ab192890; 1:2,000) and anti-GAPDH (ab181602; 1:10,000) antibodies overnight at 4°C. The next morning, the membrane was washed with TBS containing 0.05% Tween-20 (TBST) and probed with horseradish peroxidase-conjugated goat anti-rabbit IgG H&L (ab6721; 1:10,000; Abacm) at 37°C for 1 h. After being washed with TBST, the membranes were developed using Enhanced chemiluminescence kit (PerkinElmer, Inc.) and visualized using an Odyssey Infrared Imaging System (LI-COR Biosciences). The bands were quantified using ImageJ software (v1.51; National Institutes of Health) by measuring the target gene band intensity normalized to the internal control GAPDH.

Statistical analysis

All data are presented as the mean ± standard deviation for three independent experiments and analyzed by SPSS software v16.0 (SPSS, Inc.). The statistical significance among the four experimental groups was determined by a multivariate analysis of variance followed by Tukey post hoc test. P<0.05 was considered to indicate a statistically significant difference.

Results

The myocardial I/R rat model is successfully constructed

In order to examine the myocardial I/R rat model, a MedLab bio-signal system was used to monitor the heart's electrical activity through an ECG throughout the experiment (Fig. 1). Prior to myocardial ischemia, ECG results appeared normal with a normal ST segment. Following LAD coronary artery ligation for 30 min, A significant ST elevation was observed, suggesting successful ischemia. Following blood flow recovery for 2 h, the ST elevation was reduced to ~30–40% of its baseline values, indicating successful I/R injury. These data indicated the successful construction of the myocardial I/R rat model for follow-up experiments.

RSV mitigates ischemia and I/R injury on heart function

To investigate the effect of RSV on myocardial function following I/R injury, hemodynamic parameters were measured in all groups throughout the experiments (Fig. 2). No differences were identified in the baseline, LVSP, +dP/dt and -dP/dt values among the four groups (P>0.05, Fig. 2A-C). Prior to myocardial ischemia, no difference was observed in the LVSP, +dP/dt and -dP/dt values between the Control and model groups (P>0.05, Fig. 2A-C). However, when compared with the Model group, pretreatment with RSV significantly upregulated LVSP, +dP/dt and -dP/dt (P<0.05, Fig. 2A-C). During ischemia, LVSP, +dP/dt and -dP/dt in the Model group were significantly downregulated, as compared with the control group (P<0.05, Fig. 2A-C). The addition of RSV mitigated the blockage induced by ischemia, whereas the application of 3-MA suppressed the function of RSV on LVSP, +dP/dt and -dP/dt (Fig. 2A-C). Similar trends were observed during I/R damage. These data suggest that RSV pretreatment mitigated the ischemia and I/R injury on heart function, but 3-MA suppressed that function of RSV.

RSV mitigates the myocardial infarct size caused by ischemia and I/R

The myocardial infarct size was measured following different treatments. Fig. 3A shows the typical morphological characteristics of myocardial sections following TTC staining. An extensive pale infarct area was observed in the myocardial sections of rats in the Model group, which was not there in the control group. Pretreatment with RSV significantly decreased the infarct area (P<0.05). However, the pale infarct area in the myocardial sections of the 3-MA group was significantly increased, as compared with that in the RSV group sections (P<0.05). Fig. 3B shows the infarct size rate (%). These data indicated that RSV mitigated the myocardial infarct size caused by ischemia and I/R, but 3-MA suppressed the role of RSV.

RSV protects against I/R injury by inducing autophagy and blocking cytokines

A previous study revealed the relationship between ischemia and I/R and autophagy (20). To explore the mechanism by which RSV mitigates ischemia and I/R, the expression levels of autophagy markers Beclin 1 and LC-3II were mainly detected. The protein levels of PI3K, Beclin 1 and LC-3II were significantly upregulated in the Model group compared with the Control (P<0.01; Fig. 4A and B). Furthermore, the addition of RSV further enhanced those levels. However, treatment with the autophagy inhibitor 3-MA significantly blocked the upregulation induced by RSV (P<0.01). The role of RSV on cytokines was further investigated. The serum level of TNF-α in the Model group was significantly increased compared with the control group (P<0.01; Fig. 4C). However, the addition of RSV blocked the increase of TNF-α and 3-MA application inhibited the function of RSV. A similar trend was observed in serum IL-6 levels (Fig. 4D). These data suggest that RSV promoted the expression of Beclin 1 and LC-3II but blocked the serum levels of TNF-α and IL-6.

Discussion

Cardiovascular disease, including I/R injury, has been associated with high mortality worldwide. Microvascular complications are considered to play a major role in diabetic complications (21) and diabetes has been reported to cause an enhanced vulnerability of the myocardium to myocardial I/R injury (22). The aim of the present study was to explore the function of RSV against myocardial I/R injury in diabetes and to reveal the underlying mechanisms. During the heart hemodynamic function examination, the levels of LVSP, +dP/dt and -dP/dt were blocked by LAD and reperfusion. The RSV injection mitigated that blockage. However, the addition of 3-MA suppressed the function of RSV. In addition, the I/R injury-induced increase in infarct size was blocked by RSV and 3-MA reversed the function of RSV. These data provided new evidence on the function of RSV on myocardial I/R injury in diabetes. Furthermore, it was found that I/R injury enhanced the expression of Beclin 1 and LC3II and serum levels of TNF-α and IL-6. The application of RSV promoted the elevation of Beclin 1 and LC-3II but decreased the serum levels of TNF-α and IL-6. However, 3-MA reversed the effect of RSV. These results showed that RSV ameliorates diabetes-induced I/R injury through inducing autophagy and blocking cytokines TNF-α and IL-6.

Dietary phytochemicals are becoming popular as functional foods and nutritional supplements. RSV is a naturally occurring polyphenol (23), now considered a potent cardioprotective compound (24). A previous study showed that the beneficial effects of RSV on myocardial I/R injury might have a multifactorial basis (25). Certain reports have revealed that RSV is involved in cardioprotection via regulating the expression of thioredoxin-1 (26), hemeoxygenase-1 (27) and vascular endothelial growth factor (28), among others. Despite significant advances in the understanding of the function and mechanism of RSV against myocardial I/R injury, the effects and molecular basis of RSV on myocardial I/R injury under diabetic conditions remain unclear. In the present study, it was found that the application of RSV clearly elevated the levels of LVSP, +dP/dt and -dP/dt, and ameliorated the infarct size in diabetic myocardial I/R injury. These results indicated that RSV plays a role in the mechanisms of resistance to I/R injury in diabetic rats, which was consistent with a previous report (29).

Autophagy has been reported to be activated following myocardial I/R injury in cardiomyocytes (30,31). The regulation of autophagy provided a new strategy for the treatment of myocardial ischemia and heart failure (32). The blockage of autophagy is commonly achieved through the inhibition of class III PI3K via a pharmacological agent 3-MA (33). In this study, the administration of 3-MA improved the infarct size, as compared with the RSV-treated group, suggesting the close association between RSV and autophagy. A previous study showed that RSV attenuates cardiac dysfunction associated with the regulation of autophagic flux in diabetic mice (17), which was consistent with the results of the present study. Beclin-1 is the mammalian homologue of the yeast Atg6 (34) and the activation of Beclin-1 at the site of injury denotes the induction of autophagy (35). Similar to Beclin-1, LC3-II, a mammalian homologue of yeast Atg8p, is also a credible marker for autophagy (30). It was found herein that the application of RSV significantly promoted the expression of Beclin 1 and LC3-II, and that the inhibition of autophagy achieved by 3-MA significantly blocked the RSV-induced upregulation of Beclin 1 and LC3-II. These findings were consistent with those of a previous study showing that RSV induced autophagy, as evidenced by the abilities to activate autophagic markers LC3-II and Beclin-1 (36,37). It has been reported that RSV attenuated I/R-induced NLRP3 inflammasome-derived inflammation through SIRT1-dependent autophagy activity (13). A number of studies have shown that the upregulation of TNF-α and IL-6 directly leads to organ damage by aggravating the inflammatory response (3840). In this study, it was found that RSV mitigated the I/R-induced release of TNF-α and IL-6, which was in accordance with the above study. In combination, these findings provided new evidence that RSV induced autophagy and modulated inflammatory response in myocardial I/R injury in diabetes.

The successful application of RSV lies in understanding its mechanisms of action through direct and indirect interactions with pathways. In the present study, RSV decreased the levels of LVSP, +dP/dt and -dP/dt, as well the I/R injury-induced infarct size of the diabetic myocardium. The effects of RSV on I/R injury were reversed by 3-MA. RSV induced the activation of autophagy via the upregulation of Beclin 1 and LC3-II and inhibited inflammatory response via the blockage of TNF-α and IL-6. In conclusion, RSV was found to alleviate I/R injury of the diabetic myocardium via inducing autophagy and blocking inflammatory response.
