miR-424-5p通过GPR30-PI3K-AKT-mTOR信号通路调控宫颈癌的增殖、迁移和凋亡

miR-424-5p通过GPR30-PI3K-AKT-mTOR信号通路调控宫颈癌的增殖、迁移和凋亡摘要：宫颈癌作为妇科常见恶性肿瘤之一，早期诊断及治疗对保障妇女健康至关重要。miRNA是一类重要的非编码RNA，已有研究表明，在宫颈癌的发生发展中具有重要作用。本文旨在探讨miR-424-5p在宫颈癌中的作用及其机制。通过实验室的细胞实验和体内实验，我们发现miR-424-5p水平在宫颈癌组织中显著低于正常宫颈组织，且miR-424-5p的过表达对宫颈癌细胞的增殖、迁移及凋亡有抑制作用。进一步的机制研究发现miR-424-5p能够通过GPR30/PI3K/AKT/mTOR信号通路调控宫颈癌的增殖、迁移和凋亡。本研究对深入理解宫颈癌的发生发展机制，为宫颈癌的诊断和治疗提供新思路和潜在靶点。
