Association between Cytochrome P450 2C19 Gene Polymorphisms and Hematological Malignancies in an Iranian Population
Background: Cytochrome P450 2C19 (CYP2C19) is widely involved in the metabolism of some medications. On the other hand, recent studies have shown the contribution of the CYP2C19 polymorphisms to different malignancies. We aimed to investigate the association between CYP2C19 polymorphism and occurrence of hematological malignancies by comparing the phenotype distribution of this enzyme in patien...
متن کاملRelationship between genotype for the cytochrome P450 CYP2D6 and susceptibility to ankylosing spondylitis and rheumatoid arthritis.
OBJECTIVES To determine whether particular genotypes for the cytochrome P450 enzyme CYP2D6, a polymorphic enzyme, are associated with susceptibility to ankylosing spondylitis (AS) and rheumatoid arthritis (RA), or linked with any specific clinical or familial features of the two conditions. METHODS CYP2D6 genotypes were determined in 54 patients with AS, 53 patients with RA, and 662 healthy c...
متن کاملthe relation between bilingualism and translation: a case study of turkish bilingual and persian monolingual translation students
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
Quantitative analyses of electrostatic interactions between NADPH-cytochrome P450 reductase and cytochrome P450 enzymes.
A decline in the ionic interactions in the medium with increasing ionic strength (decrease in the ionic activity coefficients) was accompanied by an increase in the fast phase rate constants of CYP2B4 and CYP1A2 reduction. The stimulations were observed both in reconstituted P450 systems and in microsomes. An increase in the ionic strength from 10 to 100 mM sodium phosphate resulted in a 7-fold...
متن کاملKinetics of electron transfer between NADPH-cytochrome P450 reductase and cytochrome P450 3A4.
We have incorporated CYP3A4 (cytochrome P450 3A4) and CPR (NADPH-cytochrome P450 reductase) into liposomes with a high lipid/protein ratio by an improved method. In the purified proteoliposomes, CYP3A4 binds testosterone with Kd (app)=36±6 μM and Hill coefficient=1.5±0.3, and 75±4% of the CYP3A4 can be reduced by NADPH in the presence of testosterone. Transfer of the first electron from CPR to ...
