ABSTRACT
OBJECTIVE@#To investigate the association between the expression of caveolin-1(CAV-1) and the invasion of choriocarcinoma, and to explore the effect of CAV-1 small interfering RNA(siRNA) on the invasion of choriocarcinoma cell line JEG-3.@*METHODS@#(1) Matrigel invasion assay and 3-(4,4)-dimethylthiahiazo (-z-yl)-3,5-di-phenytetrazoliumormide (MTT) assay were used to examine the difference in invasion and proliferation ability between JEG-3 cells and JAR cells;(2) Expression of caveolin-1 gene in the human chorionic villi tissues and chorionicnoma cell lines (JEG-3 cells and JAR cells) were detected by semi-quantitative RT-PCR. (3) The effect of CAV-1 siRNA transfection on the expression of CAV-1 mRNA, and the invasion and proliferation ability of JEG-3 cells were measured by RT-PCR, Matrigel invasion assay and MTT assay.@*RESULTS@#(1) The invasion ability of JEG-3 cell line was stronger than that of JAR cell line (P0.05);(2) The expression of caveolin-1 gene in chorionicnoma cell lines was significantly stronger than that in the human normal chorion(P<0.05), and the expression of caveolin-1 gene in JEG-3 cells was stronger than that in the JAR cells (P<0.05). The data suggested that there was significantly positive correlation between caveolin-1 and the invasiveness of chorionicnoma cells (r=0.086,P<0.05);(3) CAV-1 siRNA could knock-out the expression of CAV-1 mRNA, and inhibit the invasion and proliferation ability of chorionicnoma cells.@*CONCLUSION@#CAV-1 can promote the invasion ability of chorionicnoma cells. CAV-1 siRNA can inhibit the invasion and proliferation ability of chorionicnoma cells.
