NIH tools facilitate matching cancer drugs with gene targets
- Posted: July 16, 2012
A new study details how a suite of web-based tools provides the research community with greatly improved capacity to compare data derived from large collections of genomic information against thousands of drugs. By comparing drugs and genetic targets, researchers can more easily identify pharmaceuticals that could be effective against different forms of cancer.
The study, written by the scientists that developed the tools at the National Cancer Institute (NCI), part of the National Institutes of Health, appeared in the July 16, 2012, issue of Cancer Research.
“Previously you would have to hire a bioinformatics team to sort through all of the data, but these tools put the entire database at the fingertips of any researcher,” explained Yves Pommier, M.D., Ph.D., of the NCI’s Center for Cancer Research. “These tools allow researchers to analyze drug responses as well as make comparisons from drug to drug and gene to gene.”
Researchers looking at a particular drug can use the tools to access data from previous experiments done on that drug and analyze how the drug relates to other drugs and various gene profiles. As a case example for this study, the researchers compared drug activity levels and gene expression patterns from previous research to identify an investigational compound, called NSC732298, which is not currently being studied for colon cancer, but could be a potential therapy for the disease based on a CellMiner gene-drug match. In the same exercise, the researchers were able to identify that a second investigational drug that is being tested for colon cancer, called selumetinib, might also be effective against melanoma.
“We’re looking forward to seeing how other people are going to use this tool to look at gene co-regulation, regulation of gene expression, and the relationship between gene expression and cancer,” said Pommier.
This work was supported by NCI’s Center for Cancer Research and Division of Cancer Treatment and Diagnosis under intramural project number ZIA BC 006150.
NCI leads the National Cancer Program and the NIH effort to dramatically reduce the burden of cancer and improve the lives of cancer patients and their families, through research into prevention and cancer biology, the development of new interventions, and the training and mentoring of new researchers.
