Effects of rosuvastatin on inflammatory response pathway of focal cerebral ischemia reperfusion in rats
摘要
Abstract
Objective To investigate the role of rosuvastatin in inhibiting inflammatory response pathway in rats with focal cerebral ischemia-reperfusion (I/R) . Methods Rats were randomly assigned into three groups: sham operation group, model group and experimental group, each group had 8 rats. The rats in the experimental group were lavaged with rosuvastatin 5 mg·kg-1·d-1 for 10 consecutive days before the model setting-up. The middle cerebral artery occlusion I/R model was made by the modified Zea-Longa wire bolt method. At 24 h after reperfusion, the positive cells of Toll like receptor 4 (TLR4) and nuclear transcription factor kappa B p65 (NF-κB p65) were measured by immunohistochemistry; the levels of the TLR4, NF-κB p65 protein and the TLR4, NF-κB p65 mRNA were measured by Western blotting and reverse transcription PCR, respectively. Results The expressions of TLR4 positive cells in sham group, model group and experimental group were (12. 69 ± 2. 55) cells, (38. 05 ± 6. 81) cells and (27. 80 ± 5. 75) cells, respectively;the expressions of NF-κB p65 positive cells in the three groups were (14. 64 ± 2. 79) cells, (47. 27 ± 7. 40) cells and (34. 83 ± 5. 60) cells, respectively; the expressions of TLR4 protein (optical density, OD) in the three groups were0. 28 ± 0. 04, 0. 63 ± 0. 09, 0. 41 ± 0. 07; the expressions of NF-κB p65 protein (OD) in the three groups were0. 21 ± 0. 04, 0. 72 ± 0. 12, 0. 36 ± 0. 06. Comparison between sham operation group and model group showed the difference of the factors were statistically significant (all P < 0. 05) ; comparison between model group and experimental group displayed the difference of the factors were statistically significant (all P < 0. 05) . The trend of gene results is consistent with that of protein. Conclusion Rosuvastatin can inhibit TLR4-NF-κB signal transduction pathway and reduce several inflammatory reaction after focal cerebral I/R.关键词
