(A) Dual-immunolabeling of a selective Paneth cell marker, lysozyme (red), and a general epithelial marker, β-catenin (green), in the ileac sections of wild-type and αSNAP-depleted homozygous hyh mice. Arrows indicate decreased lysozyme expression in the intestinal mucosa of αSNAP-depleted animals. (B) mRNA expression of Paneth cell markers, and regulators of Paneth cell differentiation in the whole ileac segments of these animals. Data is presented as mean ± SE (n = 6); *P<0.01 (unpaired Student’s t-test).
