这项研究表明,SOX8促进肝细胞癌 (HCC) 转移到淋巴结,与患者生存率较差相关. SOX8驱动癌细胞的入侵和扩散,这表明它是HCC的治疗目标.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 淋巴结转移 (LNM) 是肝细胞癌 (HCC) 传播和预后不佳的关键因素.
- 转录因子SOX8在HCC LNM中的作用及其预后意义目前尚不清楚.
研究的目的:
- 调查SOX8在HCC LNM中的预后意义.
- 阐明SOX8在HCC进展和转移中的机制性作用.
主要方法:
- 对387名接受手术的HCC患者的回顾性分析.
- 在初级瘤和淋巴结中使用RT-qPCR量化SOX8mRNA水平.
- 在体外测定 (扩散,迁移,入侵) 和西部斑点分析,以评估SOX8的功能影响和EMT标记物变化.
主要成果:
- 慢性肺炎,微血管侵袭和CNLC阶段是无复发生存率 (RFS) 和整体生存率 (OS) 的独立预测因素.
- 与原发性瘤相比,转移性淋巴结中的SOX8mRNA水平显著提高 (3.8倍增加).
- SOX8的淘汰抑制了HCC细胞的增殖,迁移和入侵,而过度表达增强了这些过程,由改变的上皮-介质细胞过渡 (EMT) 标记驱动.
结论:
- SOX8在HCC进展和LNM中发挥着重要作用,与减少的RFS和OS相关.
- SOX8通过EMT诱导促进HCC细胞的增殖,干细胞和入侵.
- SOX8代表了HCC治疗的潜在治疗标.
