Transcriptional Regulation of CYP2C9 Gene

CYP2C19 and CYP2C9: New aspects of pharmacogenetics and transcriptional regulation

Cytochrome P450s (CYPs) are responsible for approximately 75% of the phase Idependent drug metabolism. Several important polymorphisms in these enzymes are known to significantly affect the individual drug response. CYP2C9 and CYP2C19 are polymorphically expressed CYP family members which are responsible for the metabolism of many different clinically important drugs, e.g. anticoagulants, antid...

The transcriptional regulation of the preproenkephalin gene.

Transcriptional regulation of the human TLR9 gene.

To clarify the molecular basis of human TLR9 (hTLR9) gene expression, the activity of the hTLR9 gene promoter was characterized using the human myeloma cell line RPMI 8226. Reporter gene analysis and EMSA demonstrated that hTLR9 gene transcription was regulated via four cis-acting elements, cAMP response element, 5'-PU box, 3'-PU box, and a C/EBP site, that interacted with the CREB1, Ets2, Elf1...

Post-Transcriptional Regulation of Papillomavirus Gene Expression

Papillomavirus genomes are transcribed as one large complex transcription unit with multiple promoters, two poly(A) sites (early and late), and considerable alternative splicing. As a result, there are multiple opportunities for post-transcriptional regulation of papillomavirus gene expression. Although this area has not been as extensively studied as transcriptional regulation, there are a few...

Transcriptional regulation of the human CYP2A6 gene.

Nicotine C-oxidation is primarily catalyzed by CYP2A6 in humans. This enzymatic activity exhibits a large interindividual variability, which to a great extent is caused by genetic polymorphisms in the CYP2A6 gene. There are large interindividual differences in CYP2A6 mRNA and protein levels, but little is known about the transcriptional regulation of CYP2A6, which can, e.g., explain such differ...
