Fig. 3. PCB-induced disturbances in tight junction protein expression are not associated with alternation of steady mRNA levels.

Confluent hCMEC/D3 cultures were exposed to 5 µM of individual PCB congeners or 10 nM TCDD (positive control) for 6, 12, or 18 h. Then mRNA levels of ZO-1, ZO-2, and AF6 were determined by real-time RT-PCR. Data are mean ± SD.
