Mucins are large glycosylated glycoproteins that produced in the salivary glands, and their changes may contribute to development of xerostomia due aging accompanying deterioration oral hygiene. This study aimed characterize mucins submandibular gland (SMG) during process. SMG derived from mice each age were separated using supported molecular matrix electrophoresis (SMME). Subsequently, membra...

The molecular mechanisms required for sensing high osmolarity in the extracellular environment are not well defined in eukaryotes. A recent study showed that yeast Msb2 and Hkr1, which are related to mammalian mucins, are excellent candidates for sensing osmostress and for activating the HOG stress-activated protein kinase pathway involved in osmostress adaptation. Transmembrane mucins activate...

Mucin-type O-glycans are the primary constituents of mucins that are expressed on various mucosal sites of the body, especially the bacteria-laden intestinal tract. Mucins are the main components of mucus, which is secreted by goblet cells and forms a protective homeostatic barrier between the resident microbiota and the underlying immune cells in the colon. However, the specific role of mucin-...

Secretory epithelial cells of the proximal airways synthesize and secrete gel-forming polymeric mucins. The secreted mucins adsorb water to form mucus that is propelled by neighboring ciliated cells, providing a mobile barrier which removes inhaled particles and pathogens from the lungs. Several features of the intracellular trafficking of mucins make the airway secretory cell an interesting co...
