Objective Studies concerning the mechanism of DNA replication have advanced our understanding of genetic transmission through multiple cell cycles. Recent work has shed light on possible means to ensure the stable transmission of information beyond just DNA and the concept of epigenetic inheritance has emerged. Considering chromatin-based information, key candidates have arisen as epigenetic marks including DNA and histone modifications, histone variants, non-histone chromatin proteins, nuclear RNA as well as higher-order chromatin organization. Thus, understanding the dynamics and stability of these marks following disruptive events during replication and repair and throughout the cell cycle becomes of critical importance for the maintenance of any given chromatin state. To approach these issues, we propose to study the maintenance of heterochromatin at centromeres, key chromosomal regions for the proper chromosome segregation. Our current goal is to access to the sophisticated mechanisms that have evolved in order to facilitate inheritance of epigenetic marks not only at the replication fork, but also at other stages of the cell cycle, during repair and development. Beyond inheritance of DNA methylation, understanding how inheritance of histone variants and their modifications can be controlled either coupled or not coupled to DNA replication will be a major focus of this project. Our studies will build on the expertise and tools developed over the years in a strategy that integrates molecular, cellular, and biochemical approaches. This will be combined with the use of new technologies to monitor cell cycle (Fucci), protein dynamics (SNAP-Tagging) together with single molecule analysis involving DNA and chromatin combing. We wish to define a possible framework for an understanding of both the stability and reversibility of epigenetic marks and their dynamics at centromeres. These lessons may teach us general principles of inheritance of epigenetic states.
