Featured review: SALL4 as a transcriptional and epigenetic regulator in normal and leukemic hematopoiesis
This review by Dr. Jianchang Yang summarizes recent advances in the biology of SALL4 with a focus on its regulatory functions in normal and leukemic hematopoiesis. In the normal hematopoietic system, expression of SALL4 is mainly enriched in the bone marrow hematopoietic stem/progenitor cells (HSCs/HPCs), but is rapidly silenced following lineage differentiation. In hematopoietic malignancies, however, SALL4 expression is abnormally re-activated and linked with deteriorated disease status in patients. Further, SALL4 activation participates in the pathogenesis of tumor initiation and disease progression. Thus, a better understanding of SALL4’s biologic functions and mechanisms will facilitate development of advanced targeted anti-leukemia approaches in future.
