目的:研究诱导表达p27对HEK293细胞生长和代谢的影响。方法:将pTet-on 载体和响应于Dox的p27诱导表达载体共转
染HEK293细胞,随机挑选单克隆细胞株。以细胞周期分布和活细胞密度为主要观察指标,考察稳定转染的细胞在Dox诱导下的
细胞生长;以Qglc、Qlac 和Qgln为主要观察指标,考察转染细胞在Dox诱导下的细胞代谢。结果:p27 基因的表达使HEK293 细
胞的增殖速度显著降低,G1期细胞比例显著升高,葡萄糖消耗和乳酸生产减少。结论:诱导表达p27基因是对HEK293细胞进行
G1期阻滞的一种有效策略。 |

Objective: To investigate the effect of p27 inducible-expression on the growth andmetabolismofHEK293 cells. Methods:
The vector pTet-on and Dox-responsive p27-expressing vector were co-transfected into HEK293 cells and individual clones were isolated
randomly. Cell growth and metabolism were assessed by cell-cycle distribution and viable cell density, Qglc, Qlac and Qgln as indexes,
respectively. Results: The expression of p27 increased percentage of G1 cells, reduced consumption of glucose and production of lactate
of HEK293 cells. Conclusions: The inducible-expression of p27 is an effective strategy for G1-phase arrest of HEK293 cells. |
