摘要
MicroRNA-125a-3p通过MAPK途径调节阿尔茨海默病患者的淀粉样β蛋白 背景:据报道,miR-125a-3p在某些中枢神经系统疾病中发挥着重要作用,如阿尔茨海默病(AD)。然而,尚未对miR-125a-3p在AD病理过程中的机制进行研究。 方法:首先,我们评估了miR-125a-3p在AD队列中的表达。随后,我们改变了miR-125a-3p的表达,以评估其在细胞活力、细胞凋亡、淀粉样蛋白-β(Aβ)代谢和突触活性中的作用。最后,我们确定了其潜在的AD病理机制。 结果:本研究揭示了miR-125a-3p通过调节淀粉样前体蛋白加工的潜在功能。此外,miR-125a-3p通过成纤维细胞生长因子受体2调节丝裂原活化蛋白激酶(MAPK)途径中的Aβ代谢,影响细胞存活并激活突触表达。 结论:我们的研究表明,靶向miR-125a-3p可能是未来AD的一种适用的治疗方法。然而,需要用更多的样本进行更多的体外和体内研究来证实这些结果。
