UNLABELLED Gastrokine-2 (GKN2) is a secretory peptide of human gastric surface mucous cells (SMCs). It forms disulfide-linked heterodimers with the trefoil factor family (TFF) peptide TFF1. Binding with TFF2 was also reported. Antral SMCs differ from those of the corpus by their TFF3 expression. The aim of this study was to localize GKN2 expression along the antral gland axis, to characterize t...

AIM To assess the profile of mucins (MUC1, MUC2, MUC5AC) in gastric mucosa through immunohistochemical method. METHODS To identify metaplastic areas in gastric mucosa there was used chromoendoscopy with 0.5% solution of methylene blue, the expression of the mucins profile was determined using immunohistochemistry with MUC1, MUC5AC, MUC2 and MUC6 antibodies (clone Ma695, clone CLH2, Ccp58 and ...

BACKGROUND Mucins are large, hydrophilic glycoproteins that protect wet-surfaced epithelia from pathogen invasion as well as provide lubrication. At least 17 mucin genes have been cloned to date. This study sought to determine the mucin gene expression profile of the human male urogenital tract epithelia, to determine if mucins are present in seminal fluid and to assess the effect of androgens ...

BACKGROUND/AIMS TFF2 is a secretory peptide (106 amino acid residues) of the gastric mucosa, the porcine exocrine pancreas as well as immune cells and the CNS. It was the aim of this study to compare gastric and pancreatic TFF2. METHODS TFF2 was purified from the porcine stomach and pancreas, respectively, by size-exclusion and anion-exchange chromatography and then analyzed by Western blots ...

OBJECTIVE The expressions of cytokeratin (CK) 7 and 20 have been studied in various primary and metastatic carcinomas, and their determination may help distinguish the site of origin of metastatic carcinomas. However, little is known about the molecular basis that determines variations in CK patterns in gastric cancers (GCs). The aim of the present study was to analyze the CK expression pattern...

Little is known about the biosynthesis of mucin molecules in humans. Our aim was to examine the mucin biosynthesis (MUC2-6) along the longitudinal axis of the healthy human gastrointestinal tract. Biopsies of human stomach and small and large intestine were metabolically labeled with 35S-labeled amino acids, [35S]sulfate, or[3H]galactose, immunoprecipitated with antibodies against MUC2-6, and a...
