Die Chromatinregulation durch BAF Komplex kontrolliert kortikale Astrogenese
Zusammenfassung der Projektergebnisse
Astrocytes constitute the largest cell population in the human brain and are crucial for the brain development. Defects in astrogenesis are linked with neurological disorders such as Rett syndrome, fragile X syndrome, and brain tumors. Therefore, it is important to understand how astrocytes are generated. The ATP-dependent multi-subunit BAF (known as SWI/SNF) chromatin remodeling complexes are crucial in regulating gene expression by controlling chromatin dynamics. By interacting with epigenetic modifying enzymes, BAF complex also controls distinct epigenetic programs. By using a combination of genomic, proteomic approaches and advanced genetic manipulation and in the frame of the DFG –funded project, our research is aimed: (1) to characterize the astrocytic phenotypes of BAF170 mutant mice, (2) to study the BAF170-dependent mechanisms that control astrocytic development. The experiments have been completed as planned; the aims of study were be achieved.
