Abstract:
Objective To investigate the inhibitive effect of shRNA (short hairpin RNA) targeting APRIL gene on the pancreatic cancer cells in vitro and in vivo, in order to explore the feasibility of gene therapy for pancreatic cancer. Methods The LV-shAPRIL targeting APRIL gene had been constructed before, and was used to infect the CFPAC-1 cells. Cell proliferation and apoptosis were examined by MTT and flow cytometry. Then CFPAC-1 cells were used to construct the model of transplantation tumor into the nude mice, the tumor growth was assessed after LV-shAPRIL treatment. Results 96 hours after the LV-shAPRIL infection into CFPAC-1 cells, the cell proliferation was significantly inhibited when compared with control group and lentivirus infection group (P＜0.05 ). Flow cytometry showed the apoptosis ratio of the CFPAC-1 cells was (17.35±0.96)% in LV-shAPRIL group, which was higher than that in control group and lentivirus infection group (P＜0.05 ). After LV-shAPRIL injection into the model of nude mice, the tumor growth was slower than that in the two control groups. The tumor's volume of the LV-shAPRIL group was(821.8±123.3) mm3 and the mass was (2.16±0.18)g at 27 day, and were obviously depressed, when compared with two control groups (P±0.05). Conclusions LV-shAPRIL targeting APRIL gene can inhibit the growth of the CFPAC-1 cells in vitro and vivo. This may provide a new gene therapy approach for pancreatic cancer.
