The focused panel gene expression profile of Ishikawa cells was studied using the RT2 ProfilterTM PCR array following four-hour exposure to vehicle (DMSO) or PCAE 2 mg/mL. Fold changes greater than two (up-regulation) or smaller than 0.5 (down-regulation) were considered substantial. Fold changes were calculated by dividing expression levels in PCAE-treated cells by expression levels in the vehicle-treated cells.
