Summary of Meeting
During the past decade, a set of pathways collectively known as “RNA silencing” has been shown to use small RNA molecules to regulate gene expression and protect cells from pathogens. RNA silencing pathways control an ever-expanding range of biological phenomena, and defects in these pathways lead directly to disease. In addition, small RNAs hold great promise as therapeutic agents. The physiological mechanisms of RNA silencing are only partially understood. Furthermore, small RNAs are known to affect gene expression at many different levels, but the ways in which these different levels of silencing are integrated remain obscure. Our ability to harness RNA silencing for therapeutic purposes depends critically on our knowledge of the underlying biology. The goals of this meeting are to bring together leading researchers working on different branches of RNA silencing to share their findings and facilitate a deeper understanding of the breadth and complexity of small RNA-related phenomena.
