Abstract

The RA538 cDNA was transferred into human ovarian cancer cell line SK-OV-3 and human melanoma cell line WM-983A by its recombinant adenoviral vector constructed through homologous recombination. It was demonstrated that the recombinant adenovirus could transfer RA538 gene with high efficiency, and could obviously inhibit tumor growth, with the inhibiting rates of 85% and 73% respectively, at the same time greatly repress the colony forming ability of the cells. The therapeutic experiments on transplanted subcutaneous tumor model in nude mice demonstrated that RA538 could significantly inhibit tumor growth. Flow cytometry and DNA fragmentation analysis indicated that RA538 could induce the cell cycle G1 arrest/apoptosis of the tumor cells. The expression of c-myc gene was found pronouncedly reduced by Western blot analysis. These results suggest that the RA538 recombinant adenovirus could be a promising drug in cancer gene therapy.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
