In the second section, in vitro experiments were conducted to investigate the effects of Dex, Tween-80, Ca~2+, EDTA and Aminophylline on HeLa cell proliferation, apoptosis and its HSP70 expression.

• 本试验以地塞米松(dexamethasone,Dex)、吐温-80(Tween-80)、氨茶碱(Aminophylline)、乙二胺四乙酸(EDTA)、Ca~(2+)、双氧水(H_2O_2)为应激源,旨在探讨不同应激处理下HeLa细胞凋亡、增殖及HSP70表达的特点和规律,以及HSP70可能的表达通路。
