Gallbladder mucosa and liver tissue samples were collected in 44 patients undergoing cholecystectomy; 30 had cholesterol gallstones and the rest were stone free. Ten of the gallstone patients were treated with chenodeoxycholic acid and eight received ursodeoxycholic acid, with a daily dose of 15 mg\/kg body wt, for 3 wk before surgery.<\/jats:p>\n            <jats:p>The 3\u2013hydroxy\u20133\u2013methylglutaryl coenzyme A reductase activity, governing cholesterol synthesis, was considerably lower in the gallbladder mucosa than in liver tissue (28 \u00b1 6 and 120 \u00b1 40 pmol\/min\/mg protein). The acyl coenzyme A:acyltransferase activity in the gallbladder mucosa catalyzing the esterification of cholesterol was, on the other hand, several times higher than corresponding activity in the liver (92 \u00b1 23 and 11 \u00b1 2 pmol\/min\/mg protein). In the presence of exogenous cholesterol, the acyl coenzyme A:acyltransferase activity increased about twofold in the gallbladder mucosa.<\/jats:p>\n            <jats:p>The acyl coenzyme A:acyltransferase activity of the gallbladder mucosa from untreated gallstone patients was not stimulated further by the addition of exogenous cholesterol. Otherwise, there were no significant differences in acyl coenzyme A:acyltransferase and 3\u2013hydroxy\u20133\u2013methylglutaryl coenzyme A reductase activities in the gallbladder mucosa of gallstone patients compared with gallstone\u2013free controls.<\/jats:p>\n            <jats:p>Treatment with chenodeoxycholic and ursodeoxycholic acids did not affect the 3\u2013hydroxy\u20133\u2013methylglutaryl coenzyme A reductase activity of the gallbladder mucosa but reduced the acyl coenzyme A:acyltransferase activity by 60% to 65%. A positive correlation was obtained between the cholesterol concentration in bile and the acyl coenzyme A:acyltransferase activity in the gallbladder mucosa in the whole series of patients (Spearman's rank\u2013order correlation coefficient [r<jats:sub>S<\/jats:sub>] = 0.42, p &lt; 0.05).<\/jats:p>\n            <jats:p>We conclude that human gallbladder mucosa has a lower 3\u2013hydroxy\u20133\u2013methylglutaryl coenzyme A reductase activity but acyl coenzyme A:acyltransferase activity several times higher than that in liver tissue. Disturbance of cholesterol metabolism in the gallbladder mucosa, which might contribute to the high cholesterol content of gallbladder bile in patients with cholesterol gallstones, was not found.
