Changes in iron transporter divalent metal transporter 1 in proximal jejunum after gastric bypass

Figure 1 Morphological and immunohistochemical changes in the jejunal villus of patients subjected to Roux-en-Y gastric bypass. A and B are jejunal villus stained with haematoxylin-eosin at 0 and 6 mo after surgery, respectively. Note the preserved normal morphological pattern together with an increase of goblet cells. C and D show immunohistochemical staining for divalent metal transporter 1 during the same period, with an evident increase of such staining in the cytoplasm of epithelial cells at the apex of the villi.

Figure 2 Change in the number of goblet cells in the proximal jejunum 6 mo after Roux-en-Y gastric bypass. Wilcoxon test: Z = -2.47; P = 0.013.

Figure 3 Change in expression of divalent metal transporter 1 in the proximal jejunum 6 mo after Roux-en-Y gastric bypass. Wilcoxon test: Z = 2.04; P = 0.04.
