abstract：:The early response gene IEX-1 modulates apoptosis and cell growth in a poorly defined fashion. Here, we describe the effect of hammerhead ribozymes specifically disrupting IEX-1 expression in 293 cells. Compared to vector control, 293 cells exhibit a reduced growth rate and a slowed cell cycle progression, when stably...
