RESUMO
Wnt/ß-catenin signaling, a highly conserved pathway through evolution, regulates key cellular functions including proliferation, differentiation, migration, genetic stability, apoptosis, and stem cell renewal. The Wnt pathway mediates biological processes by a canonical or noncanonical pathway, depending on the involvement of ß-catenin in signal transduction. ß-catenin is a core component of the cadherin protein complex, whose stabilization is essential for the activation of Wnt/ß-catenin signaling. As multiple aberrations in this pathway occur in numerous cancers, WNT-directed therapy represents an area of significant developmental therapeutics focus. The recently described role of Wnt/ß-catenin pathway in regulating immune cell infiltration of the tumor microenvironment renewed the interest, given its potential impact on responses to immunotherapy treatments. This article summarizes the role of Wnt/ß-catenin pathway in cancer and ongoing therapeutic strategies involving this pathway.
