Frequency of common CYP3A5 gene variants in healthy Polish newborn infants.
Journal Title: Pharmacological Reports - Year 2009, Vol 61, Issue 5
Abstract
Cytochrome P450 monooxygenases catalyze the metabolism of approximately 40-60% of widely used drugs with a A6986G CYP3A5 polymorphism determining expresser (A6986, *1) and reduced- expresser (*3) variants with modified drug metabolism activity. In this report, the allele frequency of CYP3A5 *1 and *3 (A6986 or G6986, respectively) was analyzed by the PCR-RFLP technique in a cohort of 200 Polish newborns from the West Pomeranian region. Of the studied group, 1% (n = 2/200) proved homozygous for the CYP3A5*1 allele, 89% (n = 178/200) for the *3 allele, and 10% (n = 20/200) were heterozygous for *1/*3. Similar frequencies were found in other Caucasian European populations. This study provides basic genetic data related to the metabolism of drugs, with a narrow therapeutic window in a Polish population.

Effect of pentoxifylline on hepatic injury caused in the rat by the administration of carbon tetrachloride or acetaminophen.
The effect of pentoxifylline (PTX) on acute liver injury caused by CCl(4) or acetaminophen was studied in the rat. PTX was given twice daily (18, 36 or 72 mg/kg), intraperitoneally (ip) for 5 days prior to CCl(4) or acet...
