Comparison of total in vitro PKA activity versus in situ PKA activity from rats exposed to cigarette smoke and ethanol feeding. Rats fed 36% ethanol in their diets for 5 weeks were either sham exposed or cigarette smoke exposed for a total of 12 weeks. Tracheal epithelial cells were extracted and assayed for PKA activity in the presence (black bars) or absence (white bars) of 10 μM cAMP. Bars represent SEM of total tracheal epithelial cell PKA from six different rats (*p ≤ 0.05 for cells from ethanol-fed rats compared with control liquid diet-fed rats and **p ≤ 0.01 for cells assayed in the presence of cAMP versus the absence of cAMP).
