Personalized medicine progresses

Article Abstract:

A study examining the metabolic profile of rats develops a new approach to personalized drug treatment. The profile, which is a measurement of small molecules such as sugars and amino acids, is used to predict the response to drugs that are toxic to the liver, and the study proposes to extend the concept into humans as a way of predicting the outcome of a therapy for a given profile.
