The mucus filling the human cervical opening blocks the entry to the uterus, but this has to be relative and allow for the sperm to penetrate at ovulation. We studied this mucus, its content of proteins and mucins, and the mucin O-glycosylation in cervical secretions before, during, and after ovulation. Cervical mucosal secretions from 12 subjects were collected, reduced-alkylated, separated wi...
BACKGROUND Mucins are implicated in survival in various cancers, but there have been no report addressed on survival in appendiceal carcinoma, an uncommon disease with different clinical and pathological features from those of other colon cancers. We aimed to investigate the clinical implications of expression of mucins in appendiceal carcinoma. METHODS Expression profiles of MUC1, MUC2, MUC3...
The cells of living organisms in contact with the external environment are constantly attacked by different kinds of substances such as micro-organisms, toxins, and pollutants. With evolution, defense mechanisms, such as the secretion of mucus has been developed. Mucins are the main components of mucus. They are synthesized and secreted by specialized cells of the epithelium and in some case, b...
A 68-year-old man with chronic alcoholrelated pancreatitis and chronic nephropathy requiring dialysis was admitted to the hospital because of a 3-day history of upper abdominal pain. Laboratory tests revealed slightly elevated C-reactive protein with normal amylase and liver function test results. Computed tomography scan of the abdomen showed pancreatic calcifications and a cystic lesion in th...
Human submandibular/sublingual gland secretions contain a multimeric high molecular weight mucin (MG1) and a monomeric low molecular weight mucin (MG2). MG2 is the product of the MUC7 gene, whereas the gene for MG1 has not been identified. Previously, we isolated a clone (pSM2-1) from a human sublingual gland cDNA expression library using an antibody against deglycosylated MG1 (Troxler et al., ...
Mucin production and secretion by specialized epithelial cells is a common mechanism used by mammals to protect the underlying mucosae against various injuries (pollutants, pathogens, pH). The expression of mucin genes is cell- and tissue-specific but is submitted to variations during cell differentiation, inflammatory process, and is altered during carcinogenesis. The molecular mechanisms resp...
BACKGROUND AND AIMS Trefoil factor family (TFF) peptides and the chromosome 11p15.5 mucin glycoproteins are expressed and secreted in a site specific fashion along the length of the gastrointestinal tract. Evidence for coexpression of mucins and trefoil peptides has been suggested in numerous gastrointestinal mucosal pathologies. The ulcer associated cell lineage (UACL) occurs at sites of chron...
Primary signet-ring cell carcinoma (SRCC) of vermiform appendix is extremely rare; only three cases have been reported in the English literature. A 52-year-old woman presented with abdominal mass. Physical examination revealed bilateral huge tumors in her ovarian sites. Blood tests demonstrated anemia and elevated tumor markers (CEA, 40 ng/ml; CA125, 580 ng/ml; CA72.4, 1771 U/ml; STN-AG, 19,000...
Mucus-secreting cells of the stomach epithelium provide a protective barrier against damage that might result from bacterial colonization or other stimuli. Impaired barrier function contributes to chronic inflammation and cancer. Knock-out mice for the epithelium-specific transcription factor Spdef (also called Pdef) have defects in terminal differentiation of intestinal and bronchial secretory...
