Soluble Fiber and Insoluble Fiber Regulate Colonic Microbiota and Barrier Function in a Piglet Model

Figure 5

Gene expressions involved in the intestinal barrier (a) and sIgA concentration (b) in different groups . Letters above the bars (a, b) indicate statistical significance of gene expression among the four groups. CON, control; IDF, 1% insoluble fiber; SDF, 1% soluble fiber; MDF, 0.5% insoluble fiber +0.5% soluble fiber; ZO-1: zonula occludens 1; OCLN: occludin; CLDN-1: claudin 1; MUC1: mucin 1; MUC2: mucin 2; TNF-α: tumor necrosis factor-α; sIgA: secretory IgA.
