Abstract

Breast invasive ductal carcinoma (IDC) is a most common kind of breast cancer (BC), yet to date the corresponding effective therapies are limited. Extensive evidence has indicated that lncRNAs are involved in multiple cancers, and the potential mechanism of lncRNAs, such as LINC00092, mentioned in IDC remains elusive. IDC clinical samples from TCGA database were used to analyze the expression levels of LINC00092, miR-1827 and SFRP1. Kaplan-Meier method was applied to plot the overall survival curves. KEGG and GO were employed to screen the pathway that LINC00092 participated in. Pearson's correlation analysis determined the relationship between LINC00092 and SFRP1. Bioinformatics analysis and dual-luciferase reporter assay examined the association among LINC00092, miR-1827, and SFRP1. Cell counting kit-8, colony formation and transwell assays were performed to detect cell viability, colony formation, and migration and invasion, respectively. Quantitative reverse-transcription polymerase chain reaction and western blot were utilized to investigate the expression at RNA and protein levels. LINC00092 expression was down-regulated in IDC tissues and cells, which was correlated with poor prognosis. Down-regulated LINC00092 facilitated cell proliferation, colony formation, and cell migration and invasion, while up-regulated LINC00092 inhibited cell malignant behaviors. LINC00092/SFRP1 physically bound to miR-1827 in IDC. SFRP1 expression was proportional to LINC00092 expression and inversely proportional to miR-1827 expression. The inhibitory effects of LINC00092 on cell aggressive behaviors were partially regulated by miR-1827/SFRP1. In summary, our results indicated that overexpression of LINC00092 inhibited the development of IDC through modulating miR-1827/SFRP1 axis, suggesting new therapeutic targets to treat IDC.

摘要

乳腺浸润性导管癌(IDC)是最常见的乳腺癌(BC),但迄今为止,相应的有效治疗方法有限。大量证据表明,lncRNAs 参与多种癌症,而 LINC00092 等 lncRNAs 在 IDC 中的潜在机制仍不清楚。本研究从 TCGA 数据库中获取 IDC 临床样本,分析 LINC00092、miR-1827 和 SFRP1 的表达水平。Kaplan-Meier 法绘制总生存期曲线。KEGG 和 GO 筛选 LINC00092 参与的通路。Pearson 相关分析确定 LINC00092 与 SFRP1 的关系。生物信息学分析和双荧光素酶报告基因检测分析 LINC00092、miR-1827 和 SFRP1 之间的关系。细胞计数试剂盒-8、集落形成和 Transwell 检测分别用于检测细胞活力、集落形成和迁移侵袭。定量逆转录聚合酶链反应和蛋白质印迹法用于研究 RNA 和蛋白质水平的表达。LINC00092 在 IDC 组织和细胞中表达下调,与预后不良相关。下调 LINC00092 促进细胞增殖、集落形成和细胞迁移侵袭,而上调 LINC00092 抑制细胞恶性行为。LINC00092/SFRP1 在 IDC 中物理结合 miR-1827。SFRP1 表达与 LINC00092 表达成正比,与 miR-1827 表达成反比。LINC00092 对细胞侵袭行为的抑制作用部分受 miR-1827/SFRP1 调节。综上所述,本研究结果表明,LINC00092 的过表达通过调节 miR-1827/SFRP1 轴抑制 IDC 的发展,为治疗 IDC 提供了新的治疗靶点。
