title: The crosstalk between Wnt/β-catenin signaling pathway with DNA damage response and oxidative stress: Implications in cancer therapy.
abstract: DNA repair is essential for maintaining genomic integrity in cells. The dependence of cancer cell survival on proper DNA repair provides an opportunity to treat defective tumors by DNA damaging agents. Not only Wnt signaling has important functions in controlling gene expression, as well as cell polarity, adhesion and behavior, it also highly interacts with DNA damage response (DDR) in different levels. Furthermore, oxidative stress, which is responsible for majority of DNA lesions, affects Wnt signaling in different ways. A better understanding of the cross-talk between these pathways and events could provide strategies for treatment of cancer cells with deficient DNA repair capacity. As such, we will give a brief overview of the importance of the DNA repair machinery, signaling mechanisms of Wnt/β-catenin pathway, and DDR. We will further review the interactions between Wnt signaling and DDR, and the impact of oxidative stress on Wnt signaling. Finally, Wnt signaling is discussed as a potential treatment strategy for cancer.
