Helpful tools in the analysis of drug effects include high-throughput screening techniques such as microarrays which are used in transcriptomics and pharmacogenomics. Although we are far from using these extensive and costly tests in our daily clinical routine their application in basic research nevertheless takes us closer to individualized therapeutic strategies in which the optimal therapeutic regimen is identified for each individual patient. With the current trend toward development of specific molecular targeted therapies the translation of basic science research to clinical medicine is more important than ever. However it is similarly important to take a step back from the bedside to the bench. In the development process new therapeutic substances are extensively tested in vitro and in animal and clinical studies. These tests thoroughly describe the pharmacological and toxicological properties of the drug but they often fail to grasp the complex effects of a drug on its target cells. In many cases unexpected negative but also positive effects of a substance are only revealed after longer term clinical use. In this commentary we highlight some possible approaches to analyzing the properties of a .
