摘要: 目的:建立高效、稳定表达p21WAF1/CIP1人宫颈癌细胞株Hela-pcDNA3-WAF1。方法:应用脂质体(lipofectin)将质粒pcDNA3和重组质粒pcDNA3-WAF1分别转入人宫颈癌细胞系Hela细胞;经G418筛选,转染阳性细胞连续传代培养,并应用免疫荧光技术监测重组基因p21WAF1/CIP1翻译水平的表达活性。结果:经G418筛选,Hela细胞全部死亡,转染质粒pcDNA3和重组质粒pcDNA3-WAF1的Hela细胞存活,并可连续传代培养30代;免疫荧光技术监测p21WAF1/CIP1表达结果显示:转染重组质粒pcDNA3-WAF1的Hela细胞p21WAF1/CIP1表达阳性细胞率(92.83%)显著高于转染质粒pcDNA3(12.26%)和Hela细胞组(5.63%)(F=17 218.22,P<0.001);各代间差异无显著性(F=1.562,P>0.05)。 结论:建立一株高效、稳定表达p21WAF1/CIP1人宫颈癌细胞株Hela-pcDNA3-WAF1。

Abstract: Objective To establish a cell line Hela-WAF1 of efficient and stable expression on p21WAF1/CIP1. Methods Recombined vector pcDNA3-WAF1 and vector pcDNA3 were transferred to Hela cell line by lipofectin, respectively. These two cell lines were selected by G418, and the selected cell lines were subcultured. Hela cell line was enclosed as control group. The expression of p21WAF1/CIP1 was detected by immunofluorescence. Results After G418 selecting, Hela cell line in control group was died, and the cell lines transferring pcDNA3 and recombined pcDNA3-WAF1 were subcultured over 30 generations. The p21WAF1/CIP1 expression in Hela-pcDNA3-WAF1 was 92.83%. The results showed that recombined gene of WAF1 was more efficient expression, compared with other two groups (F=17 218.22,P<0.001); There was no significant difference in every generation (F=1.562,P>0.05). Conclusion The cell line Hela-pcDNA2-WAF1 of efficient and stable expressing p21WAF1/CIP1 is established successfully.
