ABSTRACT

BACKGROUND:

The basic treatment of malignant tumors is surgery, radiotherapy, chemotherapy. Even though, the object of these treatments is to kill cancer cells, they have limitations. So, in future studies of treatment of cancer, we should look into increasing human immune response using gene therapy in order to induce damage to tumor cells.

OBJECTIVE:

The cell growth inhibitory effect of cervical cancer cells was investigated by direct transfection using liposome(pRcCMVp53/lipofectin). and by indirect transfection using Adenovirus(AdCMVp53).

METHODS:

The cervical cancer cell lines we used in this study were HPV16 positive, having inhibitory gene, wild p53 gene, CaSki, SiHa, HPV18 positive HeLa, HeLaS3 and HPV negative C33A, HT3, LacZ gene was used as the marker gene for the transfection efficacy. Direct transfection was done by using lipofectin (pRcCMVp53/lipofectin) and indirect transfection was done by using virus, AdCMVp53. The effect of tumor cell growth inhibition was measured by cell counting assay.

RESULT:

Inhibition of growth of cervical cancer cells in cell counts of direct transfection was CaSki(88.5%), SiHa(59.1%), HeLa(86.0%), HeLaS3(78.0%), C33A(91.3%) and HT3(74.0%). Inhibition of growth of cervical cancer cells in cell counts of indirect transfection was CaSki(97.4%), SiHa(91.6%), HeLa(95.8%), HeLaS3(99.7%), C33A(97.3%) and HT3(87.4%).

CONCLUSION:

The inhibition of cell growth of cervical cancer cells by direct and indirect transfection was significantly reduced, and showed little differences depending on the type of cells. These results will have a great meaning in treating cervical cancer patients using gene therapy by direct or indirect transfection
