ABSTRACT:
A reporter vector which can evaluate the ability of a drug to induce CYP1A2 or both of CYP1A1 and CYP1A2 and a method for evaluation of the ability of a drug to induce CYP1A2 or both of CYP1A1 and CYP1A2 by using the reporter vector. A reporter system which can evaluate the ability of a drug capable of inducing CYP1A2 or both of CYP1A1 and CYP1A2 is completed by constructing a reporter vector having a reporter gene linked to the 3′ end of a region between CYP1A1 and CYP1A2 or a reporter vector having different reporter genes linked to the both ends of the region, respectively, so as to sandwich the region, and a reporter vector having a deletion mutation in the region, and confirming that the expression of a reporter molecule is increased by the drug capable of inducing CYP1A2 or both of CYP1A1 and CYP1A2 in the reporter system using the reporter vector.
