Matching directly transcriptional signatures of a disease with negatively correlated transcriptional signatures of chemical perturbations (CP) underlies the Connectivity Map (CMap) approach to identifying potential drug candidates. Similarly, correlating signatures of chemical perturbagens with genetic perturbations of specific genes has been used to identify putative targets of drugs and other...
216,105 transcriptional signatures of cellular perturbations constructed using the LINCS pilot phase L1000. The chemical perturbagen and individual shRNA signatures are created by aggregating (ie averaging) Level 4 data for biological replicates as defined by the signatures metadata. Only signatures designated to be reproducible and self-connected ("gold") by the Broad institute are represented...
