Cholesterol 135-146 LOC100508689 Homo sapiens 118-123 12032489-1 2002 A series of our studies have shown that formation of cholesterol-supersaturated bile in patients with cholesterol gallstone disease is causatively related to decreased gallbladder contractility and mucin hypersecretion by the gallbladder. Cholesterol 53-64 LOC100508689 Homo sapiens 198-203 11475792-8 2001 The mucin gel is thought to favour gallstone formation by promoting cholesterol crystal precipitation and aggregation.

Cholesterol 172-183 LOC100508689 Homo sapiens 119-124 10064729-12 1999 For pathophysiologically relevant conditions, our results clarify that mucin gel and cholesterol content, but not soluble biliary glycoproteins, promote cholesterol crystallization in human gallbladder bile. Cholesterol 153-164 LOC100508689 Homo sapiens 71-76 8895014-1 1996 BACKGROUND/AIMS: Cholesterol gallstones consist of cholesterol crystals and smaller amounts of pigments and calcium salts, arrayed on a mucin plus protein matrix. Cholesterol 17-28 LOC100508689 Homo sapiens 136-141 9741686-1 1998 Human biliary mucin and calcium binding protein (CBP) influence formation of both calcium salt precipitates and cholesterol crystals and colocalize in the center of cholesterol gallstones. Cholesterol 112-123 LOC100508689 Homo sapiens 14-19 9741686-5 1998 Mucin also stimulated, and with soluble calcium or calcium phosphate precipitates additively increased, the cholesterol crystal mass. Cholesterol 108-119 LOC100508689 Homo sapiens 0-5 9007718-8 1996 This may lead to a higher concentration of mucin in gallbladder bile and thus an increased risk of precipitation of cholesterol crystals and gallstone formation.

Cholesterol 93-104 LOC100508689 Homo sapiens 0-5 8441906-7 1993 These findings suggest that in humans, hepatic cholesterol hypersecretion is associated with the increased unsaturated fatty acid proportion in biliary phospholipids and gallbladder mucin hypersecretion, thereby causing rapid cholesterol crystal nucleation.

Cholesterol 85-96 LOC100508689 Homo sapiens 24-29 35227133-0 2022 Cholesterol crystals activate NLRP3 inflammasomes and promote gallstone formation by increasing mucin secretion. Cholesterol 0-11 LOC100508689 Homo sapiens 96-101 35227133-9 2022 We found that inflammasome activation participates in cholesterol crystal induced mucin secretion and gallstone development.

Cholesterol 39-50 LOC100508689 Homo sapiens 86-91 3655561-2 1987 Numerous low affinity binding sites for phosphatidylcholine and cholesterol were present on gallbladder mucin. Cholesterol 64-75 LOC100508689 Homo sapiens 104-109 3655561-3 1987 Binding of phosphatidylcholine and cholesterol to mucin increased as a function of cholesterol saturation index.
