CONSTITUTION: A recombinant expression vector comprises a VHL(von Hippel-Lindau) promoter of sequence number 1, 2, 3, 4, or 5, and fluorescence protein gene which is fused to the promoter. The fluorescence protein is Drosophila luciferase, enhsnce green fluorescent protein(EGFP), or cyan fluorescent protein(CFP). The VHL promoter is a promoter of sequence number 5. The fluorescence protein is Drosophila luciferase. A transformed cell line is obtained by transforming a pRL-SV40 plasmid vector containing the recombinant expression vector and renila-luciferase. A method for screening a DNA methyltransferase inhibitor comprises: a step of culturing transformed cell line in a plate; a step of adding a sample to detect and culturing in hypoxia condition; and a step of measuring fluorescence and renila-luciferase fluorescence.
