Inositol-requiring enzyme-1 (IRE1) β expression is associated with the content of mucous cells in murine nasopharynx epithelia. (a,b) Nasopharynx sections from Ire1β+/− mice (a) and Ire1β−/− mice (b) stained with Alcian Blue–Periodic Acid Schiff (AB–PAS) for visualization of goblet cells. (c) Compiled data from a and b illustrating a decreased AB–PAS staining in nasopharynx epithelia from Ire1β−/− mice. (d) Quantification of goblet cells from the nasopharynx epithelia of Ire1β+/− and Ire1β−/− mice. n = 4 animals per group. *P < 0.05, IRE1β−/− vs. IRE1β+/−.
