Effect of DLC-1 gene on tumour formation in nude mice inoculated with OVCAR-3

The aim of the present study was to examine effect of DLC-1 gene transfect OVCAR-3 cells in vivo on tumour growth in nude mice. Results showed that tumor development rate in OVCAR-3/DLC-1 group, OVCAR-3/pEGFP-C3 group and OVCAR-3 group were 87, 87 and 100%, respectively. After 40 days, tumour cells were not detected in peripheral blood of mice in every group. Low expression of P-FAK, PP130 cas and P-JNK proteins was detected in group OVCAR-3/DLC-1, while high expression was found in group OVCAR-3/pEGFP-C3 and OVCAR-3. the brightness of the bands of P130cas mRNA, FAK mRNA and JNK mRNA in group OVCAR-3/DLC-1 became weaker, while the brightness of the bands become stronger in group OVCAR-3/pEGFP-C3 and group OVCAR-3. DLC-1, as a anti-tumor related target gene, possesses a promising future.
