    Altered expression of CDX-2, PDX-1 and mucin core proteins in “Ulcer-associated cell lineage (UACL)” in Crohn’s disease

    The ulcer-associated cell lineage (UACL) induced at the site of ileac chronic ulceration in Crohn’s disease has been reported to show histological differentiation resembling gastric pyloric mucosa. To clarify ...

    Immunohistochemical localization of sodium–potassium ATPase in human normal stomach and gastric adenocarcinomas

    We studied the expression pattern of Na, K-ATPase β1 subunit in human normal stomachs and in gastric adenocarcinomas by using anti-Na, K-ATPase β1 subunit-specific monoclonal antibody. Tissue samples were proc...

    Histone H3 MRNA in situ Hybridization for Identifying Proliferating Cells in Human Pancreas, with Special Reference to the Ductal System

    In general, the incidence of proliferating cells parallels that of carcinogenesis. We have investigated proliferating activity and phenotype expression in epithelial cells in normal tissue, mucinous metaplasia...

    Helicobacter pylori infection produces expression of a secretory component in gastric mucous cells

    Helicobacter pylori infection induces the expression of a secretory component (SC) in gastric epithelial cells. We investigated the cell lineage of the SC- and immunoglobulin (Ig) A-expr...

    Helicobacter pylori infection produces reversible glycosylation changes to gastric mucins

     The protective ability of gastric mucins may depend largely on their oligosaccharide chains. We evaluated the effects of H. pylori infection on the glycosylation of gastric mucins. Gastric biopsy specimens from ...

    Differential expression of moesin in cells of hematopoietic lineage and lymphatic systems

     Moesin is a member of the ERM family consisting of ezrin, radixin, and moesin. The protein is located in the plasma membrane similarly to ezrin and radixin, and is thought to regulate cellular movements and m...
