Effects of tannic acid (TA) on mRNA expression levels of tight junction proteins in jejunal mucosa of weaned piglets. Each bar represents the average expression level with 6 independent replications. CON, piglets receiving a basal diet; CON + 0.05% TA, piglets receiving basal diet supplemented with 0.05% TA; CON + 0.1% TA, piglets receiving basal diet supplemented with 0.1% TA; CON + 0.2% TA, piglets receiving basal diet supplemented with 0.2% TA; CON + 0.4% TA, piglets receiving basal diet supplemented with 0.4% TA. ZO-1 = zonula occludens-1, ZO-2 = zonula occludens-2, OCLN = occludin, CLDN-1 = claudin-1, CLDN-2 = claudin-2. a, b Mean values with different superscript letters were significantly different (P < 0.05).
