1 The protein expressions of MUC5AC in the bronchial epithelium examined by immunohistochemistry were 4339 +/- 453, 1636 +/- 282, 3996 +/- 346, 3048 +/- 331, 2376 +/- 343 respectively in the acrolein group, the saline control group, the low dose rosiglitazone intervention group, the moderate dose rosiglitazone intervention group, and the high dose rosiglitazone intervention group, the difference being significant among groups (F = 67.74, P < 0.01). Acrolein mucin 5AC, oligomeric mucus/gel-forming Rattus norvegicus
2 The mRNA expressions of MUC5AC (the relative copies) were 35.3 +/- 10.0, 2.2 +/- 0.7, 30.5 +/- 10.2, 18.6 +/- 5.3, 10.8 +/- 2.6 respectively in the acrolein group, the saline control group, the low dose rosiglitazone intervention group, the moderate dose rosiglitazone intervention group, and the high dose rosiglitazone intervention group, the difference being significant among groups (F = 29.67, P < 0.01). Acrolein mucin 5AC, oligomeric mucus/gel-forming Rattus norvegicus
3 The expression of MUC5AC mRNA was negatively correlated with the protein expression of PPAR-gamma in the acrolein group (r = -0.880, P < 0.01). Acrolein mucin 5AC, oligomeric mucus/gel-forming Rattus norvegicus
4 PPAR-gamma and its ligand rosiglitazone inhibited acrolein-induced airway mucus hypersecretion, possibly through downregulation of MUC5AC. Acrolein mucin 5AC, oligomeric mucus/gel-forming Rattus norvegicus
