Effect of strain on ERK1/2 phosphorylation in (A) normal (NF); and (B) asthmatic fibroblasts (AF). Phosphorylation of ERK1/2 was detected by immunoblot on cell lysates using antibodies specific to the phosphorylated forms of ERK1/2 (upper panels). Equal loading of cell lysates was determined by immunoblotting with antibodies raised against total ERK1/2. Lower panels show the quantification of ERK1/2 bands. The values for phosphorylated forms of ERK 1/2 were normalized according to the values for total ERK1/2. The data represent mean ± SE. *: p < 0.05
