Description succincte (Anglais)

Specialized cellular microenvironments, or niches, control stem cells by diverse signaling pathways. However, how the signaling from a niche affects gene expression underlying stem cell behavior is poorly understood. We address this problem using the Caenorhabditis elegans model, in which maintenance of germline stem cells depends on Notch signaling from the gonadal niche. We have found that Notch activates numerous germline genes by antagonizing chromatin-based repression involving Polycomb Repressive Complex 2. Because a number of the activated genes are found to regulate self-renewal and differentiation, we hypothesize that a stem cell niche can control stem cell behavior by signaling to chromatin. This proposal is focused on elucidating the mechanism of Notch-dependent signaling to chromatin.
