Accurate Drug Repositioning through Non-tissue-Specific Core Signatures from Cancer Transcriptomes (Cell Reports)

Xu et al. generated core transcriptome signatures representing single-gene mutations for 8,476 human genes from the cancer transcriptomes in the TCGA database and developed a drug-repositioning method to predict high-specificity candidate target genes for 1,938 drugs. Applied to targeting aging pathways, 7 lifespan-extending drugs are found and functionally validated.
