Abstract
Background and Objectives
Wnt/β-catenin signaling pathway is one of the key cascades regulating development and stability of immune and blood cells, but its precise role is still controversial and is the subject of many studies. With activation of the canonical Wnt/β-catenin signaling pathway, β-catenin protein is imported into the nucleus and activates transcription of target genes including cyclin D1 and c-myc. The canonical Wnt ⁄ β-catenin signaling pathway is aberrantly activated in cancers, and it has therefore been investigated as a potential therapeutic target for the treatment of cancer. In this article, the significance of the canonical Wnt signaling pathway and its impact on blood leukemias development will be described, and how the change in the Wnt signaling pathway will cause any types of leukemia.
 
Materials and Methods
The data of the present article were obtained through the review of many papers published on the effect of Wnt / β-catenin signaling pathway on various types of leukemia.
 
Results
The review of various studies has shown that Wnt / β-catenin signaling pathway (canonical and non-canonical) is involved at a specific stage during pathogenesis of all types of hematologic malignancies.
 
Conclusions 
Since the Wnt/β-catenin signaling pathway plays an important role in the natural hematopoiesis and cellular malignancy in hematopoiesis system, evidently the changes in Wnt/ β-catenin signaling pathway provide therapeutic intervention opportunities, especially because of the significant increased level of Wnt/β-catenin signaling pathway in hematologic malignancies compared to other signaling pathways.
