中文摘要:
      摘 要:[目的] 探讨核糖体S6蛋白激酶4(ribosomal protein S6 kinase 4 gene,RSK4)基因对乳腺癌细胞Ki-67、cyclinD1、CXCR4、HIF-1α、E-cadherin基因转录影响。[方法]分别构建RSK4干扰载体、过表达载体转染至乳腺癌MCF-7细胞及MDA-MB-231细胞中,RT-PCR比较实验组和对照组Ki-67、cyclinD1、 CXCR4、HIF-1α及E-cadherin mRNA表达水平。[结果] 干扰组CXCR4、 HIF-1α、 cyclinD1 及Ki-67mRNA的转录水平分别为 2.238±0.0711、1.672±0.0833、1.540±0.0115、1.390±0.0902,与空白对照组、阴性对照组相比均升高,但E-cadherin mRNA的转录水平明显降低,差异有统计学意义(P<0.05)。过表达组Ki-67、cyclinD1、CXCR4 和 HIF-1α转录水平分别是0.603±0.0066、 0.460±0.0155、 0.424±0.0198、0.205±0.0082,与空白对照组、阴性对照组相比均降低,而E-cadherin mRNA转录水平升高,差异有统计学意义(P<0.05)。[结论] RSK4基因表达影响乳腺癌细胞增殖黏附相关基因Ki-67、cyclinD1、CXCR4、 HIF-1α和E-cadherin mRNA转录水平。
英文摘要:
      Abstract:[Purpose] To investigate the effect of RSK4 gene expression on CXCR4,HIF-1α,cyclinD1,Ki-67 and E-cadherin mRNA in breast cancer cells.[Methods] RSK4 interference lentiviral vector(RSK4-RNAi-LV) and overexpression lentiviral vector(LV-RPS6KA6) were transfected to MCF-7 cells and MDA-MB-231 cells respectively. Gene expression levels of Ki-67,cyclinD1,CXCR4,HIF-1α and E-cadherin were dectected by RT-PCR.[Results] mRNA expression levels of CXCR4,HIF-1α,cyclinD1 and Ki-67 in RNAi group(2.238±0.0711,1.672±0.0833,1.540±0.0115,1.390±0.0902) were higher than those of controls,except E-cadherin(P<0.05). The transcription levels of Ki-67,cyclinD1,CXCR4 and HIF-1α in the overexpression group(0.603±0.0066,0.460±0.0155,0.424±0.0198,0.205±0.0082)were lower than those of controls,except E-cadherin(P<0.05).[Conclusion] RSK4 gene plays an important role in the transcription of Ki-67,cyclinD1,CXCR4,HIF-1α and E-cadherin.
