Abstract

Breast cancer endangers the life of women and has become the major cause of deaths among them. MiRNAs are found to exert a regulatory effect on the migration, proliferation and apoptosis of breast cancer cells. This research aims at investigating the miR-16-5p expression and its effect on the pathogenesis of breast cancer. Their clinical data were analyzed with qRT-PCR. CCK8, EdU and Transwell was performed to explore the function of miR-16-5p in cell migration and proliferation of breast cancer cells. Dual-luciferase reporter assay, immunohistochemistry and Western blotting were carried out to explore the relation between miR-16-5p and AKT3. It was discovered that miR-16-5p was lowly expressed in breast cancer patients. Meanwhile, breast cancer patients with under-expressed miR-16-5p had a lower survival rate than those with highly expressed miR-16-5p. Furthermore, decreased miR-16-5p in cell and animal models enhanced migration and proliferation of breast cancer cells, stimulated cell cycle and reduced cell apoptosis. Finally, we found miR-16-5p restrained the NF-κB pathway and decreased gene, thereby suppressing the breast cancer development. It can be seen that miR-16-5p exhibits a low expression in breast cancer tissues, which can inhibit breast cancer by restraining the NF-κB pathway and elevating reducing AKT3.

摘要

乳腺癌危及女性生命,已成为女性死亡的主要原因。研究发现,miRNAs 对乳腺癌细胞的迁移、增殖和凋亡具有调节作用。本研究旨在探讨 miR-16-5p 的表达及其对乳腺癌发病机制的影响。采用 qRT-PCR 分析其临床数据。CCK8、EdU 和 Transwell 实验探讨 miR-16-5p 对乳腺癌细胞迁移和增殖的功能。双荧光素酶报告实验、免疫组化和 Western blot 实验探讨 miR-16-5p 与 AKT3 之间的关系。结果发现 miR-16-5p 在乳腺癌患者中低表达。同时,miR-16-5p 低表达的乳腺癌患者生存率低于 miR-16-5p 高表达的患者。此外,细胞和动物模型中 miR-16-5p 的减少促进了乳腺癌细胞的迁移和增殖,刺激细胞周期并减少细胞凋亡。最后,我们发现 miR-16-5p 抑制了 NF-κB 通路并降低了基因的表达,从而抑制了乳腺癌的发展。由此可见,miR-16-5p 在乳腺癌组织中表达较低,通过抑制 NF-κB 通路和降低 AKT3 表达来抑制乳腺癌。
