Abstract:
RNA-binding proteins (RBPs) play a pivotal role in post-transcriptional gene regulation, influencing various cellular processes, including development, differentiation, and disease progression. Emerging evidence suggests that RBPs function as critical modulators of the canonical Wnt signaling pathway, a key regulator of cell fate determination, proliferation, and tumorigenesis. By controlling the stability, localization, and translation of Wnt pathway components, RBPs fine-tune the dynamic signaling responses necessary for maintaining cellular homeostasis. Several RBPs have been identified as direct regulators of key components in the Wnt cascade, such as IGF2BP1, HuR, and MSI1, impacting their expression and activity. Dysregulation of these RBPs has been linked to aberrant Wnt signaling, contributing to various pathological conditions such as cancers or developmental disorders. This review explores the emerging landscape of RBPs in the regulation of canonical Wnt signaling, highlighting their molecular mechanism, functional implications, and potential as therapeutic targets in Wnt-driven disease.
