Caveolin-1 expression in airway smooth muscle. A) Caveolin-1 mRNA levels in lung (n = 3 in all groups). B) Caveolin-1 expression in tracheal isolated airway myocytes, measured by flow cytometry (n = 6, 7 for control and asthma model groups). C) Representative autoradiographs of caveolin-1 and cavins-1, 2 and 3 by western blot in tracheal airway smooth muscle (n = 3 in all groups). Bars represent mean ± SEM. *P < 0.01 compared with control (unpaired Student’s t-test).
