Understand how changes in chromatin topology occur during cell differentiation with HT technologies. The organization of the nuclear chromatin is extremely relevant to the biological function at the gene level and at the global nuclear level.
ESR13 will investigate how the spatial organization of chromatin affects gene regulation and differentiation. Firstly developing an optimized Hi-C kit to study chromatin interacting domains in mouse embryonic pluripotent and differentiated stem cells to identify which interacting domains are involved in cell differentiation.
As proof of concept, ESR13 will use the results obtained using ESCs. They will be fully differentiated into cardiomyocytes and compared with the functional and genome-wide analysis data published by the coordinator, L. Di Croce (P1a). Secondly, ESR13 will study the role of the chromatin in genome regulation in normal conditions and in disease by using Hi-C technology to study chromatin topological associated domains (TADs) in leukaemia and differentiated induced leukaemia cell lines.
