Objective To explore the expressions of transthyretin(TTR) mRNA and its protein in tissues of human gallbladder with cholesterol gallstones, and to explore its role in the formation of cholesterol gallstones. Methods Gallbladder were got from cases of cholesterol gallstones(cholesterol gallstones group, n=25) and cases underwent liver transplantation with normal gallbladder(normal control group, n=9) respectively, who were treated in Ren Ji Hospital and Huashan Hospital. Real time PCR(RT-PCR) and Western blot method were used to determine the expressions of TTR mRNA and its protein respectively. In addition, 2 kinds of artificial model bile system were established to test nucleation time(NT) and nucleation activity, which added TTR and albumin(ALB). Results The expression levels of TTR mRNA and protein in cholesterol gallstones group were 1.51±0.78 and 3.95±0.09 respectively, which were both higher than those of normal control group(P<0.05). The NT were(14.5±1.3)d and(18.0±0.8)d in TTR group and ALB group in small model bile system(P<0.01), which was similar with comprehensive model bile system[(13.5±0.6)d vs. (18.5±1.3)d]. The nucleation activity were 0.81 and 0.73 in small model bile system and comprehensive model bile system respectively. Conclusions Expression of TTR up-regulates in human gallbladder tissues of patients with cholesterol gallstones, and TTR plays role of nucleation in model bile system, which is related to the formation of cholesterol gallstones.
