Effect of SM on the expression of ECM-related genes assessed using an RT2 Profiler PCR Array. (A) Percentage of ECM-related genes in which the FR was ≥2.0 following SM treatment, and the percentage of those in which expression was not affected by SM. (B) Percentage of genes from each ECM-related subgroup in which the FR was ≥2.0 following SM treatment, and the percentage in which expression was not affected. BMC, basement membrane constituent; ECM, extracellular matrix; CEC, collagens and ECM structural constituents; ECP, extracellular proteases; ECPI, ECP inhibitors; OEM, other ECM molecules; SM, cigarette smoke medium; FR, fold regulation.
