| Abstrakt: | Purpose of Review: Disturbance of the delicate balance between self-renewal and differentiation in haematopoietic stem cells (HSCs) can lead to both leukaemia and bone marrow failure. The regulation of this balance in HSC biology has been intensely investigated in several model systems, and lately the importance of epigenetic modifications as well as the organization and architecture of chromatin has become increasingly recognized. In this review, we will focus on the role of the chromatin organizing protein complex cohesin in regulation of normal and malignant haematopoiesis. Recent Findings: Several functional studies in both mouse and human systems have implicated cohesin as a critical regulator of self-renewal and differentiation in HSCs. Together with the discovery of recurrent mutations of cohesin genes in myeloid malignancies, this points towards a direct role of perturbed cohesin function in leukemogenesis. Summary: The work reviewed here provides new insights about the role of the cohesin complex and chromatin architecture in normal and malignant HSCs, and indicates how cohesin may be specifically targeted for therapeutic benefit in the future. |
