Pitfalls and shortcomings of pharmacogenomic association studies: The tamoxifen controversy
Published on Feb 4, 20251684 Views
The Cytochrome P450 2D6 enzyme has been linked with tamoxifen outcome based on its role to convert the parent drug into active metabolites 4-hydroxytamoxifen and endoxifen and in particular becaus
