Targeting the canonical Wnt/β‐catenin pathway in hematological malignancies

Abstract

The canonical Wnt/β‐catenin pathway plays an important role in different developmental processes through the regulation of stem cell functions. In the activation of the canonical Wnt/β‐catenin pathway, β‐catenin protein is imported into the nucleus and activates transcription of target genes including cyclin D1 and c‐myc. Aberrant activation of the Wnt/β‐catenin pathway contributes to carcinogenesis and malignant behaviors, and Wnt signaling is essential for the maintenance of cancer stem cells. The canonical Wnt/β‐catenin pathway has been investigated extensively as a target in cancer treatment and several specific inhibitors of this signaling pathway have been identified through high‐throughput screening. In this review, the significance of the canonical Wnt/β‐catenin pathway in hematological carcinogenesis and screening methods for specific inhibitors are discussed.
