Effect of CS on Bad phosphorylation. (A) A representative immunoblot picture of Bad phosphorylation (Ser136) after 3 days, 8 weeks and 6 months of CS exposure in rat lung. Bad phosphorylation (Ser136) was unaltered after 3 days and 8 weeks but significantly decreased after 6 months of CS exposure compared to sham-exposed animals (n = 6). (B) Histograms represent the Mean ± SE of percentage of phosphorylated Bad levels. ** p < 0.01 compared sham-exposed animals.
