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 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 website 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. Emerging evidence suggests that these pathways exhibit intricate crosstalk and regulation, further complicating our understanding of Wnt signaling's translational nuances.
Beyond the β-Catenin Paradigm: Reframing Wnt Bible Translation
The canonical Wg signaling pathway has traditionally been viewed through the lens of β-catenin, highlighting its role in cellular proliferation. However, emerging evidence suggests a more intricate landscape where Wnt signaling engages in diverse mechanisms beyond canonical stimulation. This paradigm shift necessitates a reframing of the Wnt "Bible," challenging our understanding of its impact on various developmental and pathological processes.
