Detection of hTR in PNUH-12 (A) and SNU-899 (B) samples by real-time RT-PCR analysis using the LightCycler. Concomitant detection of PBGD mRNA served as a reference for relative quantification. In both cell lines, hTR levels were increased after cisplatin exposure, but, thy did not change significantly after 5-FU exposure.
