Histamine 183-192 mucin 5AC, oligomeric mucus/gel-forming Homo sapiens 132-140 22239058-1 2011 OBJECTIVE: To detect the effect of p38 mitogen activated protein kinase (p38MAPK) and cyclooxygenase-2 (COX-2) on the expression of mucin5AC (MUC5AC) in human nasal mucosa induced by histamine in vitro, and to investigate the pathogenesis of mucus hypersecretion in allergic rhinitis (AR). Histamine 183-192 mucin 5AC, oligomeric mucus/gel-forming Homo sapiens 142-148 22239058-2 2011 METHOD: Western blot was performed to detect the protein expressions of p38MAPK, COX-2 and MUC5AC in nasal mucosa induced by histamine or blocked by selective inhibitors of p38MAPK and COX-2 of different concentration gradient. Histamine 125-134 mucin 5AC, oligomeric mucus/gel-forming Homo sapiens 91-97 22239058-6 2011 COX-2 and MUC5AC increased in nasal mucosa induced by histamine in a dose-dependent manner. Histamine 54-63 mucin 5AC, oligomeric mucus/gel-forming Homo sapiens 10-16 22239058-7 2011 The histamine induced protein expressions of COX-2 and MUC5AC were dose-dependently attenuated by selective inhibitor of COX-2, namely NS-398. Histamine 4-13 mucin 5AC, oligomeric mucus/gel-forming Homo sapiens 55-61 22239058-11 2011 CONCLUSION: Our findings indicated that the histamine-induced increased expression of MUC5AC by activated p38MAPK/COX-2 may be a possible pathogenesis of mucus hypersecretion in AR. Histamine 44-53 mucin 5AC, oligomeric mucus/gel-forming Homo sapiens 86-92
