  • Study about the Relationships Between the Formation of Cholesterol Calculus and the Transporters of BSEP, MRP2 and MDR3

    【Abstract】ObjectiveTo evaluate the relationships between the transporters BSEP, MRP2, MDR3 and cholesterol calculus formation. MethodsTwenty hepatic tissue specimens were taken from consented patients with cholesterol calculus during intraoperative liver biopsy, of which ten were taken from patients without cholesterol calculus. RNA of liver tissue from all the samples was extracted and ultraviolet spectrophotometry was used to measure the content and purity of it. The mRNA and protein expressions of BSEP, MRP2 and MDR3 were determined by reverse transcriptionpolymerase chain reaction (RTPCR) and Western blot analysis, respectively. ResultsRTPCR showed that the mRNA expressions of BSEP, MRP2 and MDR3 in liver were significantly lower in patients with cholesterol calculus (0.47±0.18, 1.12±0.39 and 1.02±0.24) than those in the liver of patients without calculus (0.90±0.42, 2.48±0.89 and 1.94±0.80),P<0.01. And Western blot also showed the protein expressions of these transporters were significantly lower in patients with cholesterol calculus (90.16±18.82, 45.43±22.77 and 61.08±14.77) than those in the liver of patients without calculus (186.17±4.34, 160.47±30.19 and 100.84±15.44). ConclusionThe decreased expression of BSEP, MRP2 and MDR3 may correlate with the formation of cholesterol calculus.
