Canonical vs. Non-canonical Wnt Pathways: The Translation Quandary
Wnt signaling pathways modulate a vast array of cellular processes, from proliferation and differentiation to migration and apoptosis. These intricate networks are characterized by two major branches: the canonical, also known as the β-catenin pathway, and the non-canonical pathways, which include the planar cell polarity (PCP) and the Wnt/Ca2+ signaling cascades. While both pathways share common upstream components, they diverge in their downstream effectors and cellular outcomes. The canonical pathway primarily stimulates gene transcription via β-catenin accumulation in the nucleus, while non-canonical pathways evoke a range of cytoplasmic events independent of β-catenin. Recent evidence suggests that these pathways exhibit intricate crosstalk and more info modulation, further complicating our understanding of Wnt signaling's translational subtleties.
