BACKGROUND & OBJECTIVES Organic anion transport protein 1B1 (OATP1B1) is a major transporter protein for bile salt uptake in the enterohepatic circulation of bile salts. As the role of SLCO1B1 gene (encodes OATP1B1 or liver specific transporter-1) 388 A>G polymorphism in susceptibility towards gallstone disease is unclear the prevalence of this polymorphism in healthy north Indian population wa...

MicroRNAs (miRNAs) are a family of non-coding RNA that are able to adjust the expression of many proteins, including ATP-binding cassette transporter and organic cation transporter. We sought to evaluate the effect of miR-511 on the regulation of OATP1B1 expression by free fatty acids. When using free fatty acids to stimulate Chang liver cells, we found that the expression of miR-511 increased ...

Methods The data of 77 consecutive patients with JIA treated with MTX at the University Children’s Hospital Ljubljana from June 2011 to February 2013 have been retrospectively reviewed. The disease activity was measured by JADAS 71 score 3 and 6 months after the beginning of treatment with MTX and at the last follow up visit. All adverse events were noted separately for different organ systems....

objective(s):organic anion transporter polypeptide 1b1 (oatp1b1) encoded by solute carrier organic transporter 1b1 (slco1b1) gene; a transporter involved in the uptake of drugs and endogenous compounds is present in hepatocyte sinusoidal membrane. aim of this study was to investigate the frequencies of functionally significant snps (388a>g and 521t>c) and their haplotypes in 6 ethnic groups of ...

INTRODUCTION The efficacy of tuberculosis (TB) treatment in Human Immunodeficiency Syndrome (HIV) co-infected patients may be compromised by genetic and pharmacokinetic variation in drug disposition. Rifampicin is a critical component of TB treatment. We investigated the influence of drug transporter gene polymorphisms on rifampicin concentrations in TB-HIV co-infected patients in Durban, South...

The metabolism and disposition of statins are highly dependent on different cytochrome P450 enzymes, such as CYP3A4 and CYP2C9, as well as membrane transporters SLCO1B1, SLCO2B1, ABCB1, and ABCG2. Interindividual gene expression differences among these enzymes may explain part of the variability in tolerance and effect for statin treatment. The aim of the present study was to investigate the ef...

BACKGROUND Lowering low-density lipoprotein cholesterol with statin therapy results in substantial reductions in cardiovascular events, and larger reductions in cholesterol may produce larger benefits. In rare cases, myopathy occurs in association with statin therapy, especially when the statins are administered at higher doses and with certain other medications. METHODS We carried out a geno...
