Results of p16INK4a gene promoter methylation of normal (A) and tumor (B) lung tissues by real-time PCR. 2, 3, 5: Normal lung tissues (A); 2*, 3*, 5*: tumor lung tissues (B); 1, 4, 6: positive control (wi-38); 7: negative control (water); a: no-cut DNA amplification; b: Hpa II-cut DNA amplification; c: Msp I-cut DNA amplification. Delta Rn: the magnitude of the fluorescence signal generated during the PCR at each time point.
