The objective of this study was to determine the effects of docosahexaenoic acid monoacylglyceride (MAG-DHA) on mucin overproduction and resolution of airway inflammation in two in vitro models related to CF. Isolated human bronchi reverse permeabilized with CF transmembrane conductance regulator (CFTR) silencing (si) RNA and stable Calu3 cells expressing a short hairpin (sh) RNA directed against CFTR (shCFTR) were used. Lipid analyses revealed that MAG-DHA increased DHA\/arachidonic acid (AA) ratio in shCFTR Calu-3 cells. MAG-DHA treatments, moreover, resulted in a decreased activation of Pseudomonas aeruginosa LPS\u2013induced NF-\u03baB in CF and non-CF Calu-3 cells. Data also revealed a reduction in MUC5AC, IL-6, and IL-8 expression levels in MAG-DHA\u2013treated shCFTR cells stimulated, or not, with LPS. Antiinflammatory properties of MAG-DHA were also investigated in a reverse-permeabilized human bronchi model with CFTR siRNA. After MAG-DHA treatments, messenger RNA transcript levels for MUC5AC, IL-6, and IL-8 were markedly reduced in LPS-treated CFTR siRNA bronchi. MAG-DHA displays antiinflammatory properties and reduces mucin overexpression in Calu-3 cells and human bronchi untreated or treated with P. aeruginosa LPS, a finding consistent with the effects of resolvinD1, a known antiinflammatory mediator.<\/jats:p>","DOI":"10.1165\/rcmb.2014-0223oc","type":"journal-article","created":{"date-parts":[[2015,3,17]],"date-time":"2015-03-17T18:29:59Z","timestamp":1426616999000},"page":"574-583","source":"Crossref","is-referenced-by-count":17,"title":["Proresolving
