MicroRNAs have recently reported playing a vital role in the development of cancers. However, the role of miR-592 in renal cell carcinoma (RCC) has not been explored. In this study, the potential role of miR-592 was investigated in RCC.
The expression of miR-592 was evaluated in RCC tissues and cell lines using qRT-PCR assays. The Kaplan-Meier analysis and Cox proportional hazards model analysis was used to analyze the prognostic value of miR-592 in RCC. The effects of miR-592 on cell proliferation, migration, and invasion were determined by cell counting kit-8 (CCK-8) and Transwell assays in vitro.
The results showed that miR-592 was significantly increased both in RCC tissues and cell lines. Overexpression of miR-592 was significantly associated with lymph node metastasis, TNM stage, and poor overall survival. And functional studies in two RCC cell lines (786-O and Caki-1) have shown that overexpression of miR-592 promoted cell proliferation, migration, and invasion, while silence of miR-592 inhibited cell proliferation, migration, and invasion. SPRY2 was a direct target of miR-592.
Overall, overexpression of miR-592 may be a prognostic biomarker and therapeutic strategy for patients with RCC, which is correlated with the progression of RCC.
最近有报道称微小RNA在癌症发展中起着至关重要的作用。然而,miR - 592在肾细胞癌(RCC)中的作用尚未得到探索。在本研究中,我们调查了miR - 592在RCC中的潜在作用。
使用qRT - PCR检测法评估RCC组织和细胞系中miR - 592的表达。采用Kaplan - Meier分析和Cox比例风险模型分析来分析miR - 592在RCC中的预后价值。通过体外细胞计数试剂盒 - 8(CCK - 8)和Transwell检测法确定miR - 592对细胞增殖、迁移和侵袭的影响。
结果显示,miR - 592在RCC组织和细胞系中均显著升高。miR - 592的过表达与淋巴结转移、TNM分期及总体生存率差显著相关。在两种RCC细胞系(786 - O和Caki - 1)中的功能研究表明,miR - 592的过表达促进细胞增殖、迁移和侵袭,而miR - 592的沉默则抑制细胞增殖、迁移和侵袭。SPRY2是miR - 592的直接靶点。
总体而言,miR - 592的过表达可能是RCC患者的一种预后生物标志物和治疗策略,它与RCC的进展相关。
