The DDIT3 siRNA targeting the sequence AGA-GGC-AUA-CCA-AGA-UCC-A and NAG-1 siRNA targeting the sequence GAC-UCC-AGA-UUC-CGA-GAG-U were synthesized (Ambion, Austin, TX, USA). Cells at 50–60% confluence were transfected with the transfection reagent lipofectamine 2000 in accordance with the manufacturer's protocol, with DDIT3 or NAG-1 siRNA (Ambion) at concentrations of 5–20 nM for 48 hours. The transfected medium was removed, and the cells were treated with K8 or a vehicle for up to 48 hours. After incubation, RNA was isolated for RT-PCR, and the cells were collected for apoptosis analysis.
