ABSTRACT
Objective To explore the effect and mechanism of fragile site WWOX gene on regulating proliferation of gallbladder cancer cells in vitro. Methods The pcDNA3.0 - WWOX recombinant plasmid which was previous successfully built was transfected to GBC-SD cells and empty carrier by liposome medium. Liposome and GBC-SD were served as the negative control and the blank control,respectively. After 48 hours transfection, inverted microscope was used to observe the changes of gallbladder cancer cells' morphology,MTT and BrdU were used to detect the proliferation level of gallbladder cancer cells,and flow cytometry instrument was used to detect the change of the cell proliferation cycle. Results The results of inverted microscope shown the number of GBC-SD cells in pcDNA3.0-WWOX group decreased significantly,the suspension cells and cell debris increased,while cells in the vector control,NC and Mock groups were in normal proliferation state. MTT test showed the proliferation levels of GBC-SD cells in pcDNA3.0-WWOX group was lower than those in the control group in 24 h,48 h,72 h,96 h and 120 h,and the differences were statistically significant(P 0.05). Conclusion The overexpression of WWOX gene in vitro could effectively inhibit the proliferation activity of gallbladder cancer cells. WWOX might participate in the development of the malignant biological behavior of gallbladder cancer cells. It is expected to become a new potential target for the gene therapy to gallbladder cancer.
