Elevation of CLDN1 mRNA in human lung cancer tissues and cell lines. (A) cDNA was prepared using lung cancer cDNA arrays II and V, and then quantitative real-time PCR was performed using primer pairs for CLDN1 and β-actin. (B) cDNA was prepared from the total RNA extracted from A549, RERF-LC-AI (RERF), IA-LC, and WA-hT cells, and then real time-PCR was performed using primer pairs for CLDN1 and β-actin. The mRNA level of CLDN1 is shown relative to the values in normal lung tissues (Normal). ** p < 0.01 and * p < 0.05 compared with normal. NS, p > 0.05.
