Extracellular RNA Communication

Once thought to exist only within cells, RNA is now known to be exported from cells and play a role in newly discovered mechanisms of cell-to-cell communication. The Common Fund’s Extracellular RNA Communication (ERC) program aims to establish fundamental biological principles of extracellular RNA secretion, delivery, and impact on recipient cells; to describe exRNAs in human biofluids and the extent to which non-human exRNAs are present; to test clinical utility of exRNAs; and to provide a data and a resource repository for the community at-large.

The Extracellular RNA Communication program issued its awards in 2013. Awardees were organized into the Extracellular RNA Communication Consortium poised to achieve the overall goals of the program. This included the establishment of data standards, a publication policy, a data portal, and tools and reagents available to the scientific community. The organization of the program and the Consortium is described in the Journal of Extracellular Vesicles. 

Since founding of the program awardees have published over 428 peer-reviewed publications, including 37 publications describing refinement of protocols. At present they have generated 135 datasets, 52 software packages and 23 protocols all of which have been made available through the exRNA Portal (exRNA.org). In addition, the Consortium will be releasing a publication package with the Cell family of journals later this year. The program has received enthusiastic support from NIH leadership, and has been approved for continuation beyond the present stage of the program (contingent upon the availability of funds). In the second stage, the program will focus on the development of tools and technologies to catalyze the field of extracellular RNA communication research.
