ADAM23 methylation-specific PCR (MSP) in cell lines and lung tissues. (a) MSP of ADAM23 in primary lung cancer tissues. The results from one to twelve are the representative patients of lung cancer tissues; from 13 to 15 indicate the representative patients of adjacent normal tissues. The lanes marked U indicate the presence of the unmethylated ADAM23 gene; the lanes marked M indicate the presence of methylated ADAM23 gene. MKN-45, MKN-1 and SW480 were used as positive and negative control respectively. In the blank control (NO), water was used instead of template. (b) MSP of ADAM23 in lung cancer cell lines.
