The WNT/β-catenin signaling pathway plays a critical role in cellular proliferation

differentiation and organogenesis. Aberration activation of WNT/β-catenin pathway and dysregulation of miRNA related with this pathway are involved in oncogenesis and tumor progression in primary lung cancer. Understanding the mechanism of the WNT/β-catenin signaling pathway and illuminating the interaction between miRNA and the members of this pathway may improve the perspectives of using these molecules as potential therapeutic targets for primary lung cancer. This review focused on the participation of the WNT/β-catenin signaling pathway and miRNA in lung cancer and discussion of potential targets for this malignancy therapy in the future.
