PG - 307-13 LID - S0278-6915(13)00212-3 [pii] LID - 10.1016/j.fct.2013.03.029 [doi] AB - The purpose of this study is to investigate the effects of n-hexane extracts from bones and internal organs of Japanese eel, Anguilla japonica (HEE), on cyclooxygenase-2 (COX-2)-dependent prostaglandin D(2)(PGD(2)) generation in stem cell factor (SCF), IL-10, plus LPS-induced mouse bone marrow-derived mast cells (BMMCs) and on passive cutaneous anaphylaxis (PCA) in mice. HEE suppressed SCF/IL-10/LPS-induced PGD(2) generation, and concomitantly reduced COX-2 protein expression dose-dependently. To understand the mechanistic basis for the inhibition of PGD(2) generation by HEE, we examined the effects of HEE on upstream signaling pathways essential for COX-2 induction. HEE was found to inhibit the translocation of nuclear factor-kappaB (NF-kappaB) p65 subunit to the nucleus and its DNA-binding ability through the inhibition of TAK1, IKK and IkappaB phosphorylation. Furthermore, HEE also attenuated mitogen-activated protein kinase (MAPK)-mediated regulation of DNA binding of activator protein-1 (AP-1). Moreover, oral administration of HEE inhibited anti-dinitrophenyl (DNP) IgE-induced PCA in a dose dependent manner. Taken together, the present study provides new insights into the anti-inflammatory activity of HEE, which could be a promising candidate to be used for an inflammatory therapy.
