Intraductal papillary neoplasms of the bile duct (IPNB) shows favorable prognosis and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. Although activating point mutations of GNAS at codon 201 have been detected in approximately two thirds of IPMNs of the pancreas, there have been few studies on GNAS mutations in IPNBs. This study investigat...
PURPOSE To determine site and time of initiation of expression of the membrane-spanning mucin ASGP (rMuc4) and the goblet cell-specific, gel-forming mucin rMuc5AC by the developing rat ocular surface epithelium. METHODS Newborn Sprague-Dawley rat pups were killed at 1, 7, and 14 days after birth. Adult rats (weight, 200 g) were used as controls. Reverse transcription-polymerase chain reaction...
PURPOSE To quantify the expression of mucin 1, cell surface associated (MUC1) and mucin 16, cell surface associated (MUC16) proteins and messenger ribonucleic acid (mRNA) in a cohort of postmenopausal women (PMW), to explore the relationship between mucin expression, dry eye symptomology, and tear stability. METHODS Thirty-nine healthy PMW (>50 years of age) were enrolled in this study. No sp...
Respiratory syncytial virus (RSV) is the major cause of viral lower respiratory tract illness in children. In contrast to the RSV prototypic strain A2, clinical isolate RSV 2-20 induces airway mucin expression in mice, a clinically relevant phenotype dependent on the fusion (F) protein of the RSV strain. Epidermal growth factor receptor (EGFR) plays a role in airway mucin expression in other sy...
Mucins are highly immunogenic glycoproteins that are abundantly ex pressed by breast carcinomas and other carcinomas. The fact that deglycosylated normal mucin can induce tumor-specific monoclonal antibodies indicates that tumor-specific epitopes are hidden in the fully glycosylated form. Using recombinant DNA techniques, a fragment of mucin tandem repeats was inserted into pMal-p, an Escherich...

Mucin glycoproteins play a key role in the normal function of the airway epithelium. We examined the expression of mucin genes, MUC3, 4, 5AC, 5B, 6, 7, and 8 in human fetal tissues to establish the localization and age of onset of expression of each mucin gene during human development. We detected expression of MUC4, 5AC, 5B, and 7 in the mid-trimester airway epithelium but did not detect expre...
Airway inflammation and mucus hypersecretion/overproduction/obstruction are pathophysiological characteristics of cystic fibrosis, asthma, and chronic obstructive pulmonary disease. Up-regulation of airway mucin genes by inflammatory/immune response mediators is one of the major contributors to mucin overproduction. IL-8, a potent proinflammatory mediator and neutrophil chemoattractant, is pres...
