Canonical vs. Non-canonical Wnt Pathways: The Translation Quandary
Wnt signaling pathways orchestrate a vast array of cellular processes, from proliferation and differentiation to migration and apoptosis. These intricate networks are distinguished by two major branches: the canonical, also known as the β-catenin pathway, and the non-canonical pathways, which comprise 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 initiate a range of cytoplasmic events independent of β-catenin. Novel evidence suggests that these pathways exhibit intricate crosstalk and fine-tuning, further complicating our understanding of Wnt signaling's translational subtleties.
