Since we have established NPC cells stably expressing LMP1, we then transfected CNE1-pBabe and CNE1-LMP1 NPC stable cells with p53 construct, at 6 hr post-transfection, treated with either 25 μM LY294002 overnight (18 hr) or vehicle alone (DMSO). This evidence concerns the gene TP53 and nasopharyngeal carcinoma.
