| Outline of Final Research Achievements |
Personalized medicine based on pharmacogenomics is being developed at the clinical stage. These developments in personalized medicine are strongly supported by marked innovations in genetic analyses. However, there are currently no potential companion diagnostics for common diseases. As common diseases are multifactorial, we appreciated that drugs pass through complex metabolic pathways was important rather than experience a single enzymatic modification to predict therapeutic efficacy.
We attempted DNA microarray system in type 2 diabetes mellitus (T2DM). Sitagliptin is most popular DPP4-i, but showed individual response variability. We designed a study to develop personalized medicine of T2DM by sitagliptin based on drug metabolism. Sitagliptin is excreted through kidney and pharmacokinetics is mostly regulated by P-glycoprotein (ABCB1) and organic anion transport (OAT3). We analyzed multiple genetic variants determined by the DMET including ABCB1 and OAT3 in T2DM patients.
