RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules. Historically, RNAi was known by other names, including co-suppression, post-transcriptional gene silencing (PTGS), and quelling.The detailed study of each of these seemingly different processes elucidated that the identity of these phenomena ...

For example, C. elegans is a short-lived species in which aging appears to occur more rapidly than accumulation of damage. It is suggested that drift of developmental pathway drives the transcription circuit to aging through the elt-5/elt-6 GATA transcription factors 71,72 and through microRNAs. 73–76 An alternative mechanism other than accumulation of damage appears to drive aging in C ...
