Outline of Final Research Achievements

Stem and progenitor cells in animals have been known to change the frequency of cellular behaviors such as cell divisions and differentiation. Using the nematode, C. elegans, our studies suggest that two genes, called nhl-2 and nos-1, play an essential role in temporally arresting cell divisions and subsequent differentiation of neural progenitor cells during starvation, and that they regulate the biogenesis of a microRNA, called miR-235. Further elucidation of the mechanism that underlies the genetic and molecular interactions among these molecules under the nutritionally poor and replete conditions would help to understand how animals coordinate the cellular activity with the change in the nutritional state.
