Effect of SM on the expression of CAM-related genes assessed using an RT2 Profiler polymerase chain reaction Array. (A) Percentage of CAM-related genes in which the FR was ≥2.0 following SM treatment, and the percentage of those in which the expression was not affected by SM treatment. (B) Percentage of genes from each CAM-related subgroup in which the FR was ≥2.0 following SM treatment and the percentage of those in which expression was not affected. CAM, cell adhesion molecules; TM, transmembrane molecules CCA, cell-to-cell adhesion; SMA, cell matrix adhesion molecules; OAM, other adhesion molecules; SM, cigarette smoke medium; FR, fold regulation.
