The microRNA miR-235 couples blast-cell quiescence to the nutritional state
A microRNA, miR-235, is identified that acts downstream of the insulin/insulin growth factor signalling pathway to modulate the quiescence of blast cells in Caenorhabditis elegans.

A new DAF-16 isoform regulates longevity
The insulin/IGF-1 signalling (IIS) pathway is involved in various biological processes, including regulation of longevity. In the worm Caenorhabditis elegans, the transcription factor DAF-16a, one of two isoforms, has a major role in this pathway, regulating longevity, stress response and dauer diapause. These authors describe a new isoform, DAF-16d/f, which is also important in the regulation of lifespan. The DAF-16 isoforms functionally cooperate to fine-tune IIS-mediated processes in the context of a whole organism.
