Role of GATA-2 -77 enhancer in murine blood progenitor cells

ABSTRACT: We discovered enhancers that control GATA-2 expression during mouse development and in adult and generated mutant mouse strains that lack these enhancers, and these mice have very specific and important phenotypes that revealed GATA-2 mechanisms to control stem and progenitor cell transitions. In this study we aim to determine what proteins are under control of the GATA-2 -77 enhancer in a pool of heterogeneous blood progenitor cells with the specific focus on Socs2 expression.

Stem and progenitor cell fate transitions constitute key decision points in organismal development that enable access to a developmental path or actively preclude others. Using the hematopoietic system, we analyzed the relative importance of cell fate-promoting mechanisms versus negating fate-suppressing mechanisms to engineer progenitor cells with multilineage differentiation potential. Deletion of the murine Gata2-77 enhancer, with a human equivalent that causes leukemia, downregulates the tra  ...[more]
