Expression and Clinical Significance of Lymphoid Enhancer-Binding Factor 1 in Acute Leukemias / 中国实验血液学杂志

ABSTRACT

Lymphoid enhancer-binding factor 1 (LEF1), a key downstream effector of Wnt/β-catenin signal transduction pathway, plays a crucial role in the maintenance, proliferation and differentiation of normal hematopoietic stem/progenitor cells through regulating the transcription of its target genes. Aberrant LEF1 expression has been documented in a variety of leukemias, and implicated in the prediction of prognosis. Nevertheless, discrepancies exist regarding the expression level and clinical implication of LEF1 in different types of leukemias, suggesting LEF1 might exert distinct roles in different types of leukemia. In the present article, recent research advances of the relationship of LEF1 and regulation of hematopoiesis and leukemogenesis are reviewed.
