dc.description.abstract | We previously reported that 8-oxo-2 '-deoxyguanosine (8-oxo-dG) suppressed airway hyperresponsiveness and allergy-associated immune responses in ovalbumin-induced allergic mice by inactivating Rac. In the present study, 8-oxo-dG was investigated for its suppression of inflammation and remodeling in lung tissues induced by allergic reaction in mice. Mice were sensitized and challenged with ovalbumin without or with oral administration of 8-oxo-dG. The mice without 8-oxo-dG administration showed the following inflammatory and airway remodeling signs: infiltration of inflammatory cells into peribronchial area, hyperplasia of mucus-secreting goblet cells in bronchial walls, increase of expressions of Muc5ac and vascular cell adhesion molecule (VCAM)-1, collagen deposition and protein expression, and matrix metalloproteinase (MMP)-2/-9 expressions. We also observed an increase of various inflammation-mediating proteins, namely IL-4, IL-5, IL-8, IL-13, TNF-alpha and IFN-gamma, and activation of STAT1 and NF-kappa B. Production of reactive oxygen species and nitric oxide (NO(center dot)) was increased as indicated by a dramatic increase in formation of nitro-tyrosine. Importantly, Rac1 and 2 were also markedly activated. However, 8-oxo-dG suppressed all these inflammatory and tissue remodeling signs as well as activation of Rac1 and 2. These results indicate that 8-oxo-dG can inhibit allergy-induced inflammation and remodeling in airway and lung tissues through Rac inactivation. (C) 2010 Elsevier B.V. All rights reserved. | - |
