BACKGROUND Rosuvastatin, a novel potent HMG-CoA reductase inhibitor, is excreted into bile mediated by breast cancer resistance protein (BCRP). Our objective was to determine the association between the most frequent single nucleotide polymorphisms (SNPs) of the BCRP (421C>A) and the pharmacokinetics of rosuvastatin. METHOD Pre-screening of SLCO1B1 521TC(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Rosiglitazone is able to increase serum adiponectin levels significantly in Type 2 diabetic patients. :The role of genetic factors that determine the marked interindividual variability in glucose-lowering efficacy of rosiglitazone in Chinese patients is not known. The current study was designed to evaluate the impact(More)
1. The calcineurin inhibitor cyclosporine is widely used to prevent allograft rejection after solid organ transplantation. It has a narrow therapeutic index and shows considerable interindividual differences in its pharmacokinetics. Interindividual differences in the activity and expression of the metabolising enzymes cytochrome P450 (CYP) 3A4 and 3A5 and(More)
The present study was designed to probe the effects of Huperzine A (HupA) on diabetes-associated cognitive decline (DACD) using a streptozotocin (STZ)-injected rat model. Diabetic rats were treated with HupA (0.05 and 0.1 mg/kg) for seven weeks. Memory functions were evaluated by the water maze test. Nissl staining was selected for detecting neuronal loss.(More)
AIMS To investigate the distribution of CYP3A activity in the Chinese population, and to test for gender-related differences in CYP3A activity. METHODS Using midazolam as a probe drug, CYP3A activity in 202 Chinese healthy subjects (104 men) was measured by plasma 1'-hydroxymidazolam:midazolam (1'-OH-MDZ:MDZ) ratio at 1 h after oral administration of 7.5(More)
OBJECTIVES Our objectives were to determine whether the Gly389 polymorphism of the beta(1)-adrenergic receptor exhibits reduced responsiveness in vivo and to test the hypothesis that the Gly389Arg polymorphism affects the blood pressure and heart rate response to metoprolol. METHODS beta(1)-Adrenergic receptor genotype was determined by polymerase chain(More)
AIMS Nateglinide is a meglitinide analogue with antidiabetic action. A recent study showed that SLCO1B1 (which codes the OATP1B1 gene, also known as OATP-C, OATP2) is a major determinant which markedly affects the pharmacokinetics of repaglinide. Our objective was to assess the association between single nucleotide polymorphisms (SNPs) of SLCO1B1 and the(More)
This work evaluated the kinetic behavior of fluoxetine O-dealkylation in human liver microsomes from different CYP2C19 genotypes and identified the isoenzymes of cytochrome P450 involved in this metabolic pathway. The kinetics of the rho-trifluoromethylphenol (TFMP) formation from fluoxetine was determined in human liver microsomes from three homozygous(More)
AIMS Some study found that ATP-binding cassette (ABC) efflux transporters play an important role in antiepileptic drug resistance, especially ABCB1 and ABCC2. The aims of this study were to evaluate the relationship between the genetic polymorphisms of ABCC2 and ABCB1 and the therapeutic efficacy of antiepileptic drugs (AEDs) in Chinese epileptic patients.(More)
AIMS The purpose of this study was to investigate the association of two novel β3-adrenergic receptor (ADRB3) gene polymorphisms (Ser165Pro and Ser257Pro) with type 2 diabetes (T2DM) in the Chinese population. METHODS A total of 650 patients with T2DM and 1337 health volunteers were enrolled to conduct the association study. Two candidate polymorphisms(More)
