In order to identify how chemical compounds target genes and affect the physiology of the cell, tests of the perturbations that occur when treated with a range of pharmacological chemicals are required. By examining the haploinsufficiency profiling (HIP) and homozygous profiling (HOP) chemogenomic platforms, Lee et al. analyzed the response of yeast to thousands of different small molecules, with genetic, proteomic, and bioinformatic analyses. More than 300 compounds were identified that targeted 121 genes within 45 cellular response signature networks. These networks were used to extrapolate the likely effects of related chemicals and their impact upon genetic pathways and to identify putative gene functions.
