Electrophoresis studies of human synovial mucin.
A characteristic property of synovial fluids is the formation of a mucin clot when a weak acid is added. The physical character of the clot may be of some aid in the diagnosis of rheumatoid arthritis (Ropes, Bennett, Cobb, Jacox & Jesser, 1957; Ropes & Bauer, 1953). The clot has also been used as a preliminary step in the isolation of hyaluronic acid (Meyer, Smyth & Dawson, 1939) and its hexosa...
متن کاملStudies on the Mucin Derived from Human Colloid Breast Carcinoma.
1. A non-diffusible mucoid, showing a single peak in the ultracentrifuge, was isolated from human colloid breast carcinoma by treatment with trypsin and pepsin. The material contained threonine, leucine (isoleucine), valine, proline, glycine and glutamic acid in the approximate molar proportions 5:1:1:2:1:1. Smaller amounts of aspartic acid and serine were also found. For each 5 threonine resid...
متن کاملRheology of gastric mucin exhibits a pH-dependent sol-gel transition.
Gastric mucin, a high molecular weight glycoprotein, is responsible for providing the gel-forming properties and protective function of the gastric mucus layer. Bulk rheology measurements in the linear viscoelastic regime show that gastric mucin undergoes a pH-dependent sol-gel transition from a viscoelastic solution at neutral pH to a soft viscoelastic gel in acidic conditions, with the transi...
متن کاملThe Secretion of Gastric Mucin
The protective and lubricative r6le of mucus in the gastro-intestinal tract has been reported and studied by many investigators (Claude Bernard (4), Schiff (18), de Klug (12), Whitlow (19), Elliott (7), Pavlov (16), Berg and Jobling (3), Leriche (14), and Bucher (6)). An absolute or relative deficiency of gastric mucus has been frequently suggested as a possible etiologic factor in gastro-duode...
متن کاملmucin profile expression in gastric adenocarcinoma
background the process of neoplastic transformation in the stomach has been reported to be associated with decreased expression of normal mucins of the gastric mucosa and denovo expression of mucins that are normally expressed in other organs. this association may be used as a means to bring new insights into biologic behavior and genetic pathways in the development of gastric cancer. there are...
