Scientists at The Wistar Institute identified a new function of ADAR1, a protein responsible for RNA editing, discovering that the ADAR1p110 isoform regulates genome stability at chromosome ends and is required for continued proliferation of cancer cells. These findings, reported in Nature Communications, reveal an additional oncogenic function of ADAR1 and reaffirm its potential as a therapeutic target in cancer.

The lab of Kazuko Nishikura, Ph.D., professor in the Gene Expression & Regulation Program of The Wistar Institute Cancer Center, was one of the first to discover ADAR1 in mammalian cells and to characterize the process of RNA editing and its multiple functions in the cell.
