Abstract

BACKGROUND: miR-126-5p plays an important role in promoting endothelial cell (EC) proliferation. We thus explored whether miR-126-5p can promote EC proliferation and angiogenesis in chronically ischemic brains (CIBs). RESULTS: Improved revascularization in moyamoya patients was correlated with upregulated miR-126-5p expression in the TM and DM. In vitro experiments showed that miR-126-5p promoted EC proliferation through the PI3K/Akt pathway. CIBs from the agomir group exhibited significantly higher p-Akt, VEGF, CD31 and eNOS expression compared with the control CIBs. The ICBP and the RCF were significantly better in the agomir compared with the control group. CONCLUSION: Increasing miR-126-5p expression in the TM can promote EC proliferation and angiogenesis in CIBs of 2VO+EMS rats through the PI3K/Akt pathway. METHODS: We assessed the correlation between revascularization and miR-126-5p expression in the temporal muscle (TM) and dura mater (DM) of moyamoya patients. The effect of miR-126-5p on EC proliferation and downstream signaling pathways was explored in vitro. We established an animal model of two-vessel occlusion plus encephalo-myo-synangiosis (2VO+EMS), transfected the TM with miR-126-5p agomir/antagomir, compared the expression of miR-126-5p and relevant downstream cytokines in brain tissue among different groups, and investigated the improvement in cerebral blood perfusion (ICBP) and the recovery of cognitive function (RCF).

摘要

背景:miR-126-5p 在促进内皮细胞(EC)增殖方面发挥着重要作用。因此,我们探讨了 miR-126-5p 是否可以促进慢性缺血性脑(CIB)中的 EC 增殖和血管生成。

结果:烟雾病患者的再血管化改善与 TM 和 DM 中 miR-126-5p 表达上调相关。体外实验表明,miR-126-5p 通过 PI3K/Akt 通路促进 EC 增殖。与对照组相比,激动组的 CIB 中 p-Akt、VEGF、CD31 和 eNOS 的表达明显更高。激动组的 ICBP 和 RCF 明显优于对照组。

结论:在 2VO+EMS 大鼠中,增加 TM 中的 miR-126-5p 表达可通过 PI3K/Akt 通路促进 CIB 中的 EC 增殖和血管生成。

方法:我们评估了再血管化与烟雾病患者颞肌(TM)和硬脑膜(DM)中 miR-126-5p 表达之间的相关性。在体外研究了 miR-126-5p 对 EC 增殖和下游信号通路的影响。我们建立了两血管闭塞加脑肌血管吻合术(2VO+EMS)的动物模型,将 TM 转染 miR-126-5p 激动剂/拮抗剂,比较不同组间脑组织中 miR-126-5p 及相关下游细胞因子的表达,并研究脑血灌注(ICBP)的改善和认知功能(RCF)的恢复。
