Identification and functional characterization of novel CYP2J2 variants: G312R variant causes loss of enzyme catalytic activity

Abstract: CYP2J2 plays important roles in the metabolism of therapeutic drugs, such as astemizole and ebastine, as well as endogenous fatty acids. This study aimed to identify CYP2J2 genetic variants in Koreans and to characterize their functional consequences. From direct sequencing of the CYP2J2 gene, 12 genetic variations, including the two novel nonsynonymous mutations G312R and P351L, were identified from 93 Korean subjects. The two novel CYP2J2 variants were co-expressed with NADPH-cytochrome P450 reductase in Sf9… Show more

“…In all, 275 Korean subjects were recruited for the BCRP genotyping study. Genomic DNA samples from 159 Vietnamese, 192 Chinese, 100 African-American, and 100 Caucasian subjects were obtained from the DNA Repository of the Pharmacogenomics Research Center, Inje University (Lee et al, 2005). All the participants were healthy according to their medical histories, physical examinations, and routine laboratory tests.…”

“…CYP3A4 content was determined by difference spectroscopy, as described previously (Omura and Sato, 1964). The expression levels of the CYP3A4.1, CYP3A4.18, and CPR proteins were verified by Western blot analysis, as described previously (Lee et al, 2005b).…”

“…When gene chip was applied in the beginning, the quality of microarray was not satisfactory from clone preparation, chip production, variations from hybridization, or inadequate data analysis. However, with improved chip quality and hybridization technique, recent microarray data showed good concordance with RT-PCR or Northern blot method with reliable biological meanings (Lee et al, 2005;Davidson et al, 2006). In the present study, upregulation of the S100A4 and CTNNB1 genes or downregulation of the PTEN gene in GC9811-P were also observed using RT-PCR analysis.…”
