目的 探究健神利水方对脑出血大鼠神经细胞凋亡的作用机制。方法 通过miRNA微阵列芯片和RT-PCR分析出脑出血中miR-153的表达,观察并分析miR-153与脑出血神经细胞凋亡关系;预测miR-153的靶基因,采用双荧光素酶报告基因实验观察其与靶基因的结合情况,观察过表达和抑制miR-153对靶基因的影响,随后,明确靶基因与脑出血神经细胞凋亡关系,最后观察健神利水方对miR-153、靶基因的影响,最终探究健神利水方对脑出血大鼠神经细胞凋亡的相关机制。结果 微阵列芯片和RT-PCR检测表明miR-153在脑出血中是低表达的(P<0。05),miR-153与神经细胞凋亡呈负相关(R:-0。875,P=0。0002)。在线数据库TargetScan和miRDB显示miR-153与TREM1具有结合区域,双荧光素酶报告基因实验证明两者具有结合关系,当miR-153过表达时,TREM1表达量会下调,相反,当miR-153抑制时,TREM1表达量会上调,TREM1与神经细胞凋亡呈正相关(R:0。857,P<0。001)。健神利水方组的TREM1表达量、神经细胞凋亡数量、神经功能缺损评分均低于模型组(P<0。05),miR-153表达量高于模型组(P<0。05)。健神利水方+miR-153抑制组的TREM1表达量、神经细胞凋亡数量、神经功能缺损评分均高于健神利水方组(P<0。05)。结论 健神利水方通过促进miR-153表达,抑制TREM1表达来达到抑制脑出血大鼠神经细胞凋亡,保护神经功能。
Mechanism of Jianshen Lishui Decoction on Nerve Cell Apoptosis in Rats with Cerebral Hemorrhage Based on miR-153/TREM1
Objective To explore the mechanism of Jianshen Lishui Decoction on nerve cell apoptosis in rats with cerebral hemorrhage.Methods The expression of miR-153 in cerebral hemorrhage was analyzed by miRNA microarray and RT-PCR,and the relationship between miR-153 and neuronal apoptosis in cerebral hemorrhage was observed,and predicted the target gene of miR-153;the binding of miR-153 to target genes was studied by dual-luciferase reporter gene Experiments,and to observe the effects of overexpression and inhibition of miR-153 on target genes.Subsequently,the relationship between target genes and neuronal apoptosis in cerebral hemorrhage was determined.Finally,the effect of Jianshen Lishui Decoction on miR-153 and the target gene,and finally explored the related mechanism of Jianshen Lishui Decoction on nerve cell apoptosis in rats with cerebral hemorrhage.Results Microarray chip and RT-PCR detection showed that miR-153 was lowly expressed in cerebral hemorrhage(P<0.05),and miR-153 was negatively correlated with neuronal apoptosis(R:-0.875,P=0.0002).The online databases TargetScan and miRDB showed that miR-153 has a binding region with TREM1,and the dual-luciferase reporter gene demonstrated a binding relationship between the two.When miR-153 was overexpressed,the expression of TREM1 was down-regulated,conversely,up-regulated when miR-153 was repressed,and TREM1 was positively correlated with nerve cell apoptosis(R:0.857,P<0.001).The expression of TREM1,the number of nerve cell apoptosis and the score of Neurological Deficit Scores in the Jianshen Lishui Decoction group were lower than those in the model group(P<0.05),and the expression of miR-153 was higher than that in the model group(P<0.05).The expression of TREM1,the number of nerve cell apoptosis and the score of Neurological Deficit Scores in the Jianshen Lishui Decoction +miR-153 inhibition group were higher than those in the Jianshen Lishui Decoction group(P<0.05).Conclusion Jianshen Lishui Decoction inhibits the apoptosis of nerve cells and protects the neurologicalfunctions in rats with cerebral hemorrhage by promoting miR-153 expression and inhibitingTREM1 expression.
