    Abstract: The present invention relates to a cell line in which an expression construct is introduced into a genomic DNA, the expression construct including: (a) a promoter operable in animal cells and heterologous to adenoviruses; and (b) a modified adenovirus E1 coding gene sequence of SEQ ID NO:1 operatively linked to the promoter. According to the present invention, the cell line of the present invention is a novel cell line which is less likely to produce a replication competent adenovirus (RCA). The adenovirus producing cell line of the present invention has a low possibility of producing RCA due to homologous recombination, when compared with conventional cell lines. Therefore, this makes it possible to regulate the required amount of virus during gene therapy using the adenovirus and prevent tissue damage and toxic effects caused by overproduction of the adenovirus.

The induced differential stress resistance results in improved resistance to cytotoxicity in normal cells, which, in turn, reduces cytotoxic side-effects due to chemotherapy, as well as improved effectiveness of chemotherapeutic agents.
