Abstract

Wnt signaling regulates several cellular processes, including differentiation, proliferation, and stem cell pluripotency. Mutations in Wnt signaling are known to lead to tumor initiation and progression. Wnt/ β-catenin signaling is dysregulated in breast cancer, where it has been shown to mediate oncogenic progression. In this review, the canonical and non-canonical pathways of Wnt/ β-catenin signaling, and their regulation of breast cancer oncogenesis and progression are described. During the last decade, several small molecules and natural compounds have shown to interfere with Wnt signaling and demonstrate potential as Wnt-targeting therapeutic agents. This review also highlights these molecules, some of which are in clinical trials. Finally, strategies of using these molecules in combination therapies with other drug agents are discussed.
