Effect of FAK, DLC-1 gene expression on OVCAR-3 proliferation

The study investigates the effect of FAK, DLC-1 on OVCAR-3 proliferation. FAK gene siRNA vector recombinant plasmid was constructed using RNA interference technique. FAK gene-transfected OVCAR-3 cells, OVCAR-3 cells with DLC-1 gene expression, and OVCAR-3 cells with simultaneous expression of DLC-1 and FAK genes were obtained using gene transfection technology. In addition, siRNA control group and blank control were also given. Effect of FAK, DLC-1 gene expression on OVCAR-3 proliferation was examined by FCM and Cell Counting Kit-8 (CCK-8) methods. Results showed that DLC-1 gene high expression and FAK gene silencing, single silencing FAK gene, and single DLC-1 gene high expression in OVCAR-3 cells may decrease S and G2/M phase proportion of the cell cycle. Moreover, DLC-1 gene high expression and FAK gene silencing in OVCAR-3 cells can display the most significant effect. This confirmed that DLC-1 gene high expression and FAK gene silencing may significantly inhibit the OVCAR-3 cells proliferation. CCK-8 analysis showed that silence FAK gene exprssion or/and increasing DLC-1 gene expression may decrease OVCAR-3 growth rate. Moreover, simultaneous silence the exprssion of FAK gene and high expression of DLC-1 gene can display the most significant effect on OVCAR-3 growth. It can be concluded that downregulation of FAK gene expression or/and upregulation of DLC-1 gene expression can all inhibit the OVCAR-3 growth. Moreover, DLC-1 gene expression and FAK gene silencing can display the most marked inhibitory effect on the OVCAR-3 growth.
