Abstract:
Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.
