Pharmacogenomics in type 2 diabetes management: towards personalized medicine
Journal of Translational Medicine volume 10, Article number: A19 (2012)
There is inter-individual variability in the responses to anti-diabetic treatments, partly due to genetic factors involved in drug absorption, distribution, metabolism and target. The identification of genetic markers related to drug reaction can help physicians with the decisions of drug selection, dose titration, treatment duration, and avoidance of advert drug reactions. We focused on the effects of susceptibility genes for T2D on anti-diabetic drugs’ efficacy. With respect to repaglinide, genetic variants at multiple loci such as CYP2C8, SLCO1B1, KCNJ11, TCF7L2 and SLC30A8, affect either its pharmacokinetics or pharmacodynamics. We also made some efforts on pharmacogenetic studies of repaglinide efficacy. We recruited a total of 104 Chinese patients with type 2 diabetes and with no history of prior antidiabetic medications, to whom subsequent repaglinide monotherapy with a 48-week follow-up was applied. Based on studies on this cohort, genetic variations at KCNJ11, ABCC8, NOS1AP and KCNQ1 were found to be associated with repaglinide efficacy. Moreover, we also focused on investigations into possible genetic factors for rosiglitazone efficacy, and have already suggested effects of ABCA1 and SLC30A8 variants on the response to rosiglitazone treatment. In spite of all these advances in the field of pharmacogenetics of type 2 diabetes, the pace of clinical application of these findings is rather slow. Consequently, more researches especially randomized clinical trials into the practical utility should be conducted.
