A blog post at Ars Technica describes a recently published paper in PLoS Computational Biology that used search engine algorithms to predict best therapeutic drug combinations. “The basic algorithm used by the researchers involves walking through a tree with nodes that are combinations of the drugs and doses present in the system,” writes Matt Ford. Applying three separate algorithms to keeping fruit flies safe from heart problems and inducing apoptosis in cancer cells, they found that their methods outperformed random testing of drugs and doses. One obvious application is for personalized medicine. Says Ford, “The authors suggest that this technique, combined with the molecular profile of a disease, could lead to better treatment regimes for that disease, which could then be further customized based on an individual’s biological profile.”
