BACKGROUND: The Beclin 1 gene binds to the apoptosis-inhibiting protein Bcl-2. The expression and function of the Beclin 1 gene in four colorectal cancer cell lines (HT29, DLD-1, SW480, SW620) was investigated. MATERIALS AND METHODS: The expression of Beclin 1 mRNA was examined by reverse transcription-polymerase chain reaction (RT-PCR), the cell growth rate of a stable cell line established after transfection of the Beclin 1 gene into low Beclin 1-expressing HT29 colon cancer cells. In addition, changes in cell cycle were investigated by flow cytometry, and the expression levels of cell cycle related proteins in the Beclin 1 transfected colon cancer cell line were assessed. RESULTS: The expression level of Beclin 1 mRNA in the colon cancer cell lines was variable. Transfection of the low Beclin 1 gene-expressing colon cancer cell line with the Beclin 1 gene resulted in cell growth inhibition. The cell cycle analysis showed that the percentage of GJ-phase cells was significantly higher

背景: Beclin 1基因结合的凋亡抑制蛋白Bcl - 2 。表达及功能的Beclin 1基因在4个结肠癌细胞系( HT29 ,发展学习科- 1 , SW480 , SW620 )的影响。材料与方法:表达Beclin 1 mRNA的检测逆转录聚合酶链反应( RT - PCR ) ,对细胞生长率的稳定细胞系的建立转染后的Beclin 1基因进入低Beclin 1表达HT29结肠癌癌细胞。此外,改变细胞周期的影响,流式细胞仪和表达水平的细胞周期相关蛋白在Beclin 1转染结肠癌细胞株进行了评估。结果:表达水平Beclin 1 mRNA在结肠癌细胞株的变数。转低Beclin 1基因表达结肠癌细胞株的Beclin 1基因导致细胞生长抑制。细胞周期分析表明,该百分比连接期细胞明显高于转Beclin 1比模拟转染细胞。的表达水平cyclin E和Rb蛋白磷酸化下降。结论:这些结果表明, Beclin 1可以抑制结肠癌细胞

背景: Beclin 1个基因束缚对apoptosis禁止的蛋白质Bcl-2。 Beclin的表示和作用在四结肠直肠的癌症细胞系(HT29、DLD-1、SW480, SW620)的1个基因被调查了。 材料和方法: Beclin表示1 mRNA由反向副本聚合酶链式反应(RT-PCR),在Beclin的转染以后建立的稳定的细胞系的细胞增长率审查1个基因入低Beclin 1表达的HT29结肠癌细胞。 另外,在细胞周期上的变化由cytometry的流程调查,并且细胞周期的表示水平关系了在估计1 transfected结肠癌细胞系的Beclin的蛋白质。 结果: Beclin的表示水平在结肠癌细胞系的1 mRNA是易变的。 低Beclin的转染与Beclin的1基因表达的结肠癌细胞系1个基因导致细胞成长禁止。 细胞周期分析表示, GJ阶段细胞的百分比是显着高在Beclin 1 transfectants比在嘲笑transfected细胞。 cyclin E和磷酸化的铷的表示水平被减少了。 结论: 这些结果表明Beclin 1可能禁止结肠直肠的癌细胞成长。
