Abstract:Cell type-specific transcription factors governing hematopoietic stem and progenitor cell transitions establish networks containing hundreds of genes and proteins. Network complexity renders it challenging to discover essential versus modulatory or redundant components. This scenario is exemplified by GATA2 mechanisms that control hematopoiesis during embryogenesis. Loss of a far upstream Gata2 enhancer (-77) disrupts the GATA2-dependent genetic network governing hematopoietic progenitor cell differentiation (… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
