As shown in Figures 2(c) and 2(d), the AOM/DSS-treated mice showed a significant elevation in the number of mucin-depleted foci and aberrant crypt foci when compared to the control group, while the quercetin+AOM/DSS cotreated group showed decreased formations of mucin-depleted foci and aberrant crypt foci. The gene discussed is MUC5AC; the disease is infectious otitis media.
