Hepatocellular carcinoma (HCC) is one of the most common types of cancer that is associated with poor quality of life in patients and a global health burden. The mechanisms involved in the development and progression of HCC remain poorly understood.
Hepatocellular carcinoma human samples and cell lines were subjected to qRT-PCR for expression assessment. CCK-8 assay, Transwell migration and invasion assay, were applied for cell function detection. Animal experiment was used to measure the function of SNHG17 on cell growth . Western blot was conducted to evaluate the level of EMT in cells. RIP, RNA pull-down and luciferase reporter assays were performed to assess the correlation between SNHG17, miR-3180-3p and RFX1.
Our study demonstrated that SNHG17 was upregulated in HCC human samples and involved cell proliferation, migration, invasion progress. SNHG17 promoted HCC cell growth and metastasis . Furthermore, we investigated the downstream factor of SNHG17, SNHG17 acted as a molecular sponge for miR-3180-3p, and SNHG17 regulated RFX1 expression via miR-3180-3p. SNHG17 promotes tumor-like behavior in HCC cells via miR-3180-3p/RFX1.
We determined RFX1 as the target of miR-3810-3p; SNHG17 enhanced the progression of HCC via the miR-3180-3p/RFX1 axis. Taken together, our findings may provide insight into the molecular mechanism involved in the progression of HCC and develop SNHG17 as a novel therapeutic target against HCC.
肝细胞癌(HCC)是最常见的癌症类型之一,与患者生活质量差及全球健康负担相关。HCC发生和发展所涉及的机制仍知之甚少。
对肝细胞癌人类样本和细胞系进行qRT-PCR以评估表达情况。采用CCK-8检测、Transwell迁移和侵袭检测来检测细胞功能。利用动物实验来测定SNHG17对细胞生长的作用。进行蛋白质免疫印迹法以评估细胞中上皮-间质转化的水平。进行RNA免疫沉淀、RNA下拉和荧光素酶报告基因检测以评估SNHG17、miR-3180-3p和RFX1之间的相关性。
我们的研究表明,SNHG17在HCC人类样本中上调,并参与细胞增殖、迁移、侵袭过程。SNHG17促进HCC细胞生长和转移。此外,我们研究了SNHG17的下游因子,SNHG17作为miR-3180-3p的分子海绵,且SNHG17通过miR-3180-3p调节RFX1表达。SNHG17通过miR-3180-3p/RFX1促进HCC细胞中的肿瘤样行为。
我们确定RFX1是miR-3810-3p的靶标;SNHG17通过miR-3180-3p/RFX1轴增强HCC的进展。综上所述,我们的研究结果可能为HCC进展所涉及的分子机制提供见解,并将SNHG17开发为一种针对HCC的新型治疗靶点。
