Abstract

Breast cancer (BC) poses a huge threat to women's health. Growing evidence has shown lncRNAs play critical roles in BC progression. However, the effect of LINC00536 in BC remains unknown. LINC00536, miR-4282, and centromere protein F (CENPF) expressions in BC cells were determined using qPCR assay. Colony formation assay was employed to evaluate the cell proliferation of BC cells. Besides, cell migration and invasion were evaluated using the transwell assay. FISH assay was employed to analyze LINC00536 and miR-4282 locations in BC cells. Additionally, dual luciferase reporter gene assay was performed to verify the binding relationships between LINC00536 and miR-4282, miR-4282 and CENPF. Here, our results displayed that LINC00536 and CENPF were overexpressed in BC cells, while miR-4282 was downregulated. LINC00536 could negatively regulate miR-4282 expression via directly binding to miR-4282. LINC00536 silence suppressed the proliferation, migration, and invasion of BC cells, which was abolished by miR-4282 inhibition. Additionally, miR-4282 could negatively regulate CENPF expression via directly binding to CENPF. MiR-4282 overexpression suppressed BC development, which was abolished by CENPF overexpression. Finally, we proved that LINC00536 silencing suppressed BC growth via regulating the miR-4282/CENPF axis in vivo. Our research displayed that LINC00536 acted as an oncogene in BC. LINC00536-enhanced BC cell proliferation, migration, and invasion. Moreover, LINC00536 functioned as a ceRNA to exert malignant characteristics in BC via the miR-4282-CENPF axis. Collectively, our results demonstrated that the LINC00536-miR-4282-CENPF axis was a critical player in BC development and was a promising target for BC therapy.

摘要

乳腺癌(BC)对女性健康构成巨大威胁。越来越多的证据表明,长链非编码 RNA(lncRNA)在 BC 进展中发挥着关键作用。然而,LINC00536 在 BC 中的作用尚不清楚。采用 qPCR 检测 BC 细胞中 LINC00536、miR-4282 和着丝粒蛋白 F(CENPF)的表达。采用集落形成实验评估 BC 细胞的增殖能力。此外,通过 Transwell 实验评估细胞迁移和侵袭能力。采用 FISH 实验分析 BC 细胞中 LINC00536 和 miR-4282 的位置。此外,还进行了双荧光素酶报告基因实验来验证 LINC00536 和 miR-4282、miR-4282 和 CENPF 之间的结合关系。结果显示,LINC00536 和 CENPF 在 BC 细胞中高表达,而 miR-4282 则下调。LINC00536 可通过与 miR-4282 直接结合来负调控 miR-4282 的表达。沉默 LINC00536 可抑制 BC 细胞的增殖、迁移和侵袭,而 miR-4282 抑制则可消除这一作用。此外,miR-4282 可通过与 CENPF 直接结合来负调控 CENPF 的表达。过表达 miR-4282 可抑制 BC 的发展,而过表达 CENPF 则可消除这一作用。最后,我们在体内证实,LINC00536 通过调节 miR-4282/CENPF 轴抑制 BC 的生长。研究表明,LINC00536 在 BC 中发挥癌基因作用。LINC00536 增强 BC 细胞的增殖、迁移和侵袭能力。此外,LINC00536 通过 LINC00536-miR-4282-CENPF 轴发挥恶性特征。综上所述,LINC00536-miR-4282-CENPF 轴在 BC 发展中起着关键作用,是 BC 治疗的有前途的靶点。
