Summary

Dr. Kathleen Giacomini, a professor at UCSF, delivers a comprehensive lecture on pharmacogenomics and personalized medicine. She begins by outlining the goals of the field: identifying genetic risk factors for adverse drug reactions and non-response, and ultimately using genomic information to tailor drug therapy. She highlights the FDA’s label changes for six drugs, including tamoxifen, where genetic testing can guide treatment. She explains how a common variant in the CYP2D6 gene affects tamoxifen metabolism and relapse-free survival in breast cancer patients. She then discusses genome-wide association studies (GWAS) for diseases like diabetes and coronary artery disease, and their application to drug response, citing Mary Relling’s work on methotrexate toxicity in childhood leukemia. She introduces a global collaboration between the Pharmacogenetics Research Network and Japanese researchers to pool resources for large-scale studies. The latter half focuses on her lab’s research on membrane transporters, particularly OCT1, and its role in metformin response. Using mouse models and human genetic data, she shows that OCT1 variants affect metformin’s efficacy in lowering blood glucose. She concludes by emphasizing the importance of integrating genetic and environmental factors to optimize drug therapy.
