We constructed a series of chimeric genes containing part of the first exon and increasingly longer 5 ' flanking sequences of the ODC gene fused to either bacterial chloramphenicol acetyltransferase ( CAT ) or luciferase reporter genes .
 GENE: ODC gene; GENE: bacterial chloramphenicol acetyltransferase; GENE: CAT; GENE: luciferase reporter genes
