Objective To investigate the proliferation and apoptosis effects of adenovirus-mediated interleukin-24 (Ad-IL-24) gene on Karpas299 cells in vitro. Methods The Karpas299 cells were divided into blank control group, Ad-IL-24 group, and the adenovirus which carrying green fluorescent protein gene group (Ad-GFP group). Karpas299 cells of Ad-IL-24 group were infected by adding 200.0 μL Ad-IL-24, Karpas299 cells of Ad-GFP group were infected by adding 200.0 μL Ad-GFP, but Karpas299 cells of blank control group were treated by adding 200.0 μL PBS. Cells' proliferation inhibition rates of 3 groups were detected by cell counting kit (CCK-8) method at 12, 24, and 48 hours after treatment, respectively, and the cells' apoptosis rates of 3 groups were detected by flow cytometry at 48 hours after treatment. Results Ad-IL-24 can suppress the growth of Karpas299 cells, and the inhibition rate increased over time. Compared with Ad-GFP group at the same time, the cell' proliferation inhibition rate of Ad-IL-24 group was higher at 12, 24, and 48 hours after treatment (P<0.05). In addition, the cells' apoptosis rate of Ad-IL-24 group was higher than those of Ad-GFP group and blank control group at 48 hours after treatment (P<0.05). Conclusion Ad-IL-24 can suppress the growth of Karpas299 cells and induce the apoptosis of it.
