Wnt/β-catenin signaling pathway. The Wnt signaling pathway plays a major role in development and is also essential for stem cell regulation and tissue homeostasis. WebOct 22, 2009 · In addition, we showed that poorly differentiated cell lines express noncanonical Wnt ligands such as Wnt5a acting as an antagonist of canonical Wnt signaling. Thus, it appears that HCC cells may activate or repress their canonical Wnt signaling, using autocrine/paracrine systems based on selective use of canonical and …
