WebMucin is a glycosylated material secreted by epithelial cells. Mucin is thought to be responsible for abnormal thrombotic events in patients with tumors that produce these … Mucins are secreted as massive aggregates of proteins with molecular masses of roughly 1 to 10 million Da. Within these aggregates, monomers are linked to one another mostly by non- covalent interactions, although intermolecular disulfide bonds may also play a role in this process. Secretion [ edit] See more Mucins are a family of high molecular weight, heavily glycosylated proteins (glycoconjugates) produced by epithelial tissues in most animals. Mucins' key characteristic is their ability to form gels; therefore they are a … See more Human mucins include genes with the HUGO symbol MUC 1 through 22. Of these mucins, the following classes have been defined by … See more The functional classification does not correspond to an exact evolutionary relationship, which is still incomplete and ongoing. Known-related groups include: • The … See more Mucin genes encode mucin monomers that are synthesized as rod-shaped apomucin cores that are post-translationally modified by exceptionally abundant glycosylation. The dense "sugar coating" of mucins gives them considerable water-holding capacity and also makes … See more Mature mammalian mucins are composed of two distinct regions: • The amino- and carboxy-terminal regions are very lightly glycosylated, but rich in cysteines. … See more Mucins have been found to have important functions in defense against bacterial and fungal infections. MUC5B, the predominant mucin in the mouth and female genital tract, … See more Upon stimulation, MARCKS (myristylated alanine-rich C kinase substrate) protein coordinates the secretion of mucin from mucin-filled vesicles within the specialized epithelial cells. Fusion of the vesicles to the plasma membrane causes release of the mucin, which as … See more

WebMucin is a protein made by cells. It is used to make a thick fluid called mucus. Mucus is normally found in saliva and other substances throughout the body. When viewed under the microscope, mucin has a light blue or grey colour. A special stain called mucicarmine makes can be performed to highlight mucin inside cells. Tumours that produce mucin WebAug 19, 2016 · A periodic acid-Schiff stain demonstrates diffuse cytoplasmic mucin, with apparent basal sparing because of the nuclei.

WebJul 31, 2024 · Seventeen showed decreased cytoplasmic mucin (UEA), one with intracytoplasmic mucin (mucinous), and one with signet ring cell type cells. Five cases did not demonstrate the above features. Two of these cases were diagnosed as MDA on initial cervical biopsy and resection specimen. WebAmong the secreted mucins, MUC2 has been linked to inflammation and cancer. MUC2 contains a large centrally located PTS domain, which is extensively O-glycosylated, and … WebJun 7, 2024 · Scattered tumor cells with cytoplasmic mucin were also present; however, ciliated cells and serous gland-like granules were absent. Tumor cells also proliferated within the tracheal epithelium adjacent to the polypoid lesion. Neither infiltration growth into the tracheal wall nor necrosis was observed (Fig. 1C–F).
