Abstract

To investigate the possibility of prohibitin (PHB) inhibition by lentiviral vector-mediated RNA interference (RNAi) and its influence on cell apoptosis in the retinoic acid-resistant acute promyelocytic leukemia cell line NB4-R1, a lentiviral vector encoding a short hairpin RNA (shRNA) targeted against PHB (pGCSIL-GFP-PHB) was constructed and transfected into the packaging cells 293T, and the viral supernatant was collected to transfect NB4-R1 cells. Quantitative real-time fluorescent PCR and western blotting were used to detect the expression levels of PHB. Flow cytometry and detection of enzymatic activity of caspase‑3 by western blotting were employed to examine cell apoptosis. Our results provide evidence that the lentiviral vector pGCSIL-GFP-PHB was constructed successfully, and the PHB mRNA and the protein expression inhibitory rates were 90.3 and 95.8%, respectively. When compared to the control group, the activity of caspase‑3 decreased significantly, which showed a 57.3% downregulation, and the apoptosis rate was reduced by 44.6% (P<0.05). In conclusion, downregulation of the PHB gene may inhibit apoptosis of NB4-R1 cells, and it is speculated that this was at least partly due to the downregulation of caspase‑3, and PHB may be a novel target for gene therapy for retinoic acid-resistant acute promyelocytic leukemia.
