Canonical vs. Non-canonical Wnt Pathways: The Translation Quandary
Wnt signaling pathways regulate a vast array of cellular processes, from proliferation and differentiation to migration and apoptosis. These intricate networks are defined by two major branches: the canonical, also known as the β-catenin pathway, and the non-canonical pathways, which encompass 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 activates click here gene transcription via β-catenin accumulation in the nucleus, while non-canonical pathways evoke a range of cytoplasmic events independent of β-catenin. Emerging evidence suggests that these pathways exhibit intricate crosstalk and fine-tuning, further expanding our understanding of Wnt signaling's translational complexity.
