Gene silencing through RNA interference (RNAi) has emerged as a powerful tool for understanding gene function. Over the past several years, high-throughput RNAi screens have illuminated a wide variety of biological processes, ranging from genes that affect the activity of therapeutic agents to novel components of signaling pathways. For example, on Nov. 25, 2013, NIH announced that scientists have used RNAi technology to identify dozens of genes that may represent new therapeutic targets for treating Parkinson’s disease. The research was published online in Nature. Now, data on the biochemical makeup of small interfering RNA molecules is available publicly. On Dec. 11, 2013, NIH announced that, for the first time, these data now are accessible to researchers worldwide.
NIH established a state-of-the-art RNAi screening facility that accepts proposals from any NIH researcher. The staff at this facility, administered by the NCATS Division of Pre-Clinical Innovation, assist investigators with all stages of project planning and execution, beginning with assay development through genome-wide siRNA screens, informatics/pathway analysis and rigorous follow-up. Genome-wide siRNA screens for humans and mice are available. Also routinely included in screens are miRNA mimic and inhibitor libraries.
