LncRNA snaR对人肝细胞癌迁移与侵袭的调控机制研究

发布时间:2021-03-24 17:44
  [目 的]肝细胞癌(hepatocellular carcinoma,HCC)是原发性肝癌的一种,是世界范围内常见的恶性肿瘤之一,尤其在我国和东南亚高发,且是由癌症导致死亡的常见疾病。肿瘤转移是肿瘤相关死亡的主要原因。然而,驱动肿瘤转移的机制尚未完全研究清楚。长链非编码RNA snaR(long non-coding RNA snaR,Lnc RNA snaR)是一种肿瘤激活因子,研究发现Lnc RNA snaR可在多种癌症中发挥致癌作用,但在HCC中的尚未有研究报道。据报道,上皮间质转化(Epithelial mesenchymal transition,EMT)、基质金属蛋白酶(matrix metalloproteinase,MMPs)、转化生长因子β1(transforming growth factor-β1,TGF-β1)、细胞外调节蛋白激酶(extracellular regulated protein kinases,ERK)、JAK 激酶/信号转换器和转录激活因子 3(Janus kinase/signal transducer and activator of th...
