The discovery of genes that are responsible for cell responses to drugs, i.e., pharmacogenes, is a key task in pharmacogenomics. In this work we propose a new approach for pharmacogenes identification integrating: i) a filter and a wrapper feature selection technique, and ii) three sources of knowledge, namely transcriptional profiles, drugs activity, and path- way interactions. We show that the integration of multiple feature selection approaches as well as of several sources of knowledge increases the accuracy of the results.

Abstract

The discovery of genes that are responsible for cell responses to drugs, i.e., pharmacogenes, is a key task in pharmacogenomics. In this work we propose a new approach for pharmacogenes identification integrating: i) a filter and a wrapper feature selection technique, and ii) three sources of knowledge, namely transcriptional profiles, drugs activity, and path- way interactions. We show that the integration of multiple feature selection approaches as well as of several sources of knowledge increases the accuracy of the results.
