Objective To survey carboxypeptidase E(CPE) mRNA expression by cDNA microarray and real-time PCR in the liver of patients with cholesterol gallstone(CGS),and to reveal the role of CPE in the formation of CGS.

• 目的:利用基因芯片和实时定量聚合酶链反应(real-time PCR)分析胆囊胆固醇结石病人肝脏中羧肽酶E(carboxypeptidase E,CPE)的mRNA表达,探讨CPE与胆囊胆固醇结石形成可能相关的分子机制。
