A. Schematic structure of the mutation reporter shuttle plasmid, pUCNIM. The non-B DNA-forming sequences (shown as “Non-B”) or the control sequence can be inserted between the lacZ gene and the promoter such that the function of the lacZ gene is maintained. B. RT-PCR analysis of dexamethasone-induced transcription through the non-B DNA-forming sequence (CG14) or control sequence in pUCG14 and pUCON plasmids. Primers were designed to bind sequences in the lacZ gene. RT-PCR products were subjected to agarose gel electrophoresis and visualized by ethidium bromide staining.
