Oral administration of Bifidobacterium sp. increases DRA expression in mouse colon. A: relative abundance of DRA mRNA was measured using gene-specific primers in ileal and colonic mucosa of mice treated with vehicle and live Bifidobacterium sp. Values are means ± SE of 5 mice. *P < 0.01 vs. control. B: representative Western blot for DRA protein levels in mucosal tissue lysates (top) and densitometric analysis of relative band intensities (bottom). Values are means ± SE of 4 mice. *P < 0.05, **P < 0.01 vs. control.
