Bladder cancer is a prevalent malignancy of the urinary system, in which long non-coding RNAs (lncRNAs) are highly associated. We aimed to elucidate the role of LINC00958 in bladder cancer.
LINC00958 expression levels were measured using qRT-PCR. The interaction of LINC00958-miR-490-3p-AURKA was analyzed by luciferase, RIP, and RNA pull-down assays. The biological roles of LINC00958, miR-490-3p, and AURKA in bladder cancer cells were analyzed using CCK8, BrdU, and transwell assays.
Increased expression of LINC00958 and AURKA was observed in bladder cancer tissues and cell lines. Decreased LINC00958 expression repressed bladder cancer progression and downregulation of miR-490-3p accelerated bladder cancer cell progression. Moreover, LINC00958 sponges miR-490-3p to upregulate AURKA expression, thereby promoting carcinogenesis in bladder cancer cells.
Our study revealed that LINC00958 facilitated cell proliferation and invasion, and suppressed cell apoptosis by sponging miR-490-3p and upregulating AURKA, thus inspiring a new treatment method for bladder cancer.
膀胱癌是泌尿系统常见的恶性肿瘤,其中长链非编码 RNA(lncRNA)高度相关。我们旨在阐明 LINC00958 在膀胱癌中的作用。
使用 qRT-PCR 测量 LINC00958 的表达水平。通过荧光素酶、RIP 和 RNA 下拉测定分析 LINC00958-miR-490-3p-AURKA 的相互作用。使用 CCK8、BrdU 和 Transwell 测定分析 LINC00958、miR-490-3p 和 AURKA 在膀胱癌细胞中的生物学作用。
在膀胱癌组织和细胞系中观察到 LINC00958 和 AURKA 的表达增加。降低 LINC00958 的表达抑制了膀胱癌的进展,而下调 miR-490-3p 加速了膀胱癌细胞的进展。此外,LINC00958 作为 miR-490-3p 的海绵,上调 AURKA 的表达,从而促进膀胱癌细胞的癌变。
我们的研究表明,LINC00958 通过海绵 miR-490-3p 和上调 AURKA 促进细胞增殖和侵袭,抑制细胞凋亡,从而为膀胱癌提供了一种新的治疗方法。
