Effects of 5'-N-ethylocarbo-xamidoad-enosine on brain ischemia-reperfusion oxidative injury and levels of miR-29b and miR-125b in rats
摘要
Abstract
Objective To investigate the effects of 5'-N-ethylocarbo-xamidoad-enosine(NECA)on cerebral ischemia-reperfusion oxidative injury and the levels of miR-29b and miR-125b in rats.Methods SD rats were divided into sham-operation,model,experimental and positive control groups with 12 rats in each group.Cerebral ischemia-reperfusion model was established in all the other 3 groups except control group.7 days before modeling,sham-operation group and model group were intraperitoneally injected with the same amount of normal saline,and experimental group was injected with 1.5 mg·kg-1 NECA,and positive control group was injected with 2.0 mg·kg-1 nimodipine.The rats in 4 groups were given the drug once a day for 7 days.Cerebral ischemia-reperfusion model was established by middle cerebral artery embolization in all the other 3 groups except sham-operation group.After the modeling was successful,the serum oxidative stress indexes glutathione(GSH),superoxide dismutase(SOD),catalase(CAT),malondialdehyde(MDA)of rats were determined by enzyme-linked immunosorbent assay,and the levels of miR-29b and miR-125b in brain tissue were detected by real-time fluorescence quantitative polymerase chain reaction.Results The SOD levels of sham-operation,model,experimental and positive control groups were(57.82±6.87),(10.75±0.24),(32.24±3.42)and(29.45±4.11)U·mL-1;the levels of GSH were(20.62±3.12),(9.45±1.92),(16.78±1.85)and(15.39±2.02)U·mg-1;the levels of CAT were(3.25±0.42),(0.85±0.11),(2.18±0.34)and(1.98±0.32)U·L-1;the levels of MDA were(0.42±0.09),(1.35±0.42),(0.75±0.06)and(0.72±0.08)nmol·mg-1;the expression levels of miR-29b in brain tissue were 1.02±0.11,0.42±0.02,0.84±0.08 and 0.87±0.10;the expression levels of miR-125b in brain tissue were 1.00±0.11,0.48±0.05,0.75±0.08 and 0.74±0.07,respectively.There were statistically significant differences between sham-operation group and model group(all P＜0.05).Compared with experimental group and positive control group,there were statistically significant differences in the above indexes(all P＜0.05).Conclusion NECA can improve oxidative damage and increase the expression levels of miR-29b and miR-125b in cerebral ischemia-reperfusion rats.关键词
