The three best characterized Wnt signaling pathways are the canonical Wnt pathway, the noncanonical planar cell polarity pathway, and the noncanonical Wnt/calcium pathway.

This review explores the molecular mechanisms underlying Wnt pathway activation, highlighting its critical components and examining upstream factors that may influence its function. Additionally, the …
