Based on the structure and function of a molecule, mucin is subdivided into 3 categories: membrane-bound mucins (MUC1, MUC3 MUC4, MUC12, MUC16, MUC17), gel-forming (secreted) mucins (MUC2, MUC5AC, MUC5B, MUC6, MUC19), and soluble mucin (
MUC7).
Salivary glycoconjugates such as mucins (MUC1, MUC4, MUC5B,
MUC7, and MUC19), proline-rich glycoproteins (PRGs), and kallikrein may also ensure the appropriate hydration of the oral mucosa and maintain the proper pH of the stimulated and nonstimulated saliva [8, 9].
DAMP TLR Refs (i) Biglycan and decorin are degraded TLR2 and by saliva from NOD.B10 mice TLR4 [95] (ii) Versican is increased in SGEC lines TLR2/6 [108] from SS patients heterodimer (i) Fibronectin is dysregulated in salivary [109] tissue from SS mice and upregulated in [110] saliva from SS patients [95] (ii) Calprotectin (S100A8/A9) levels are TLR4 [111] elevated in sera, salivary tissue, and [112] saliva of pSS patients [113] (iii) MUC5B and
MUC7 are mislocalized [114] in the ECM of pSS patients [115] (i) Long interspersed nuclear element 1 [116] (LINE-1) is increased in MSG tissue TLR 7/8 [117] from SS patients
Higher levels of salivary MUC5B and
MUC7 in individuals with gastric diseases who harbor Helicobacter pylori .
The
MUC7 gene variant produces the protein that makes spit slimy and holds tight to microbes, preventing them from entering your body through your mouth.
5-HTT intron 2 and

Two-hybrid analysis of human salivary mucin
MUC7 interactions.
Relation extraction task was formally put forward in
MUC7 by Message Understanding Conference (MUC) supported by Defense Advanced Research Projects committee (DARPA) in 1998.
Over expression, aberrant intracellular localization, and changes in glycosylation of MUC1 and
MUC7 are often reported in tumors of colon, breast, ovarian, lung, and pancreatic origin [24, 48].
Human breast tissue was used as a control for MUC1; human colon for MUC2, 3 and 4; human gastric mucosa for MUC5AC and 6; human bronchial mucosa for MUC5B, and human submandibular salivary gland for
MUC7. Negative controls consisted of sections from normal human liver, as it does not express any of these mucin genes.
