The gene expression profiles of 6 main ABC transporters (MDR1, MRP1, MRP3, MRP4, MRP5, and BCRP) were established in lymphocytes from birth to adulthood using blood samples from 57 children and 15 adults (34 and 5 HIV-infected, respectively). Gene expression levels were quantified by quantitative RT-PCR. In adults, the MRP1 gene had the highest expression, followed by the MRP5 gene. BCRP and MRP4 genes were significantly higher expressed at birth than after 1 month of life. Neither HIV infection nor antiretroviral therapies modulated the gene expression profiles of ABC transporters. In conclusion, drugs that are substrates of BCRP and MRP4, like zidovudine, may have an altered efficacy in newborns. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
