Our understanding of the genetic mechanisms of organismal aging has advanced dramatically during the past two decades. With the development of large-scale RNAi screens, the last few years saw the remarkable identifications of hundreds of new longevity genes in the roundworm Caenorhabditis elegans. The various RNAi screens revealed many biological pathways previously unknown to be related to aging. In this review, we focus on findings from the recent large-scale RNAi longevity screens, and discuss insights they have provided into the complex biological process of aging and considerations of the RNAi technology will continue to have on the future development of the aging field.
