The Canonical Wnt Signaling (Wnt/β-Catenin Pathway): A Potential Target for Cancer Prevention and Therapy
Precise regulation of signal transduction pathways is crucial for normal animal development and for maintaining cellular and tissue homeostasis in adults. The Wnt/Frizzled-mediated signaling includes canonical and non-canonical signal transduction pathways. Upregulation or downregulation of the canonical Wnt-signaling (or the Wnt/β-Catenin signal transduction) leads to a variety of human diseas...

will break the barrier, making the TJ a frequent contributor to a vast range of pathologies of blood vessels and epithelial organs. Since most of these insults have pleotropic cellular effects, it is difficult to envision therapies that could target specific TJ components or functions. In contrast, some assaults on the barrier are quite specific. For example, house dust mites excrete a fecal pr...
متن کاملRac1 augments Wnt signaling by stimulating β-catenin–lymphoid enhancer factor-1 complex assembly independent of β-catenin nuclear import
β-Catenin transduces the Wnt signaling pathway and its nuclear accumulation leads to gene transactivation and cancer. Rac1 GTPase is known to stimulate β-catenin-dependent transcription of Wnt target genes and we confirmed this activity. Here we tested the recent hypothesis that Rac1 augments Wnt signaling by enhancing β-catenin nuclear import; however, we found that silencing/inhibition or up-...
متن کاملSnapShot: Wnt/β-Catenin Signaling
Molecules labeled in green and blue play positive and negative roles in Wnt/β-catenin signaling, respectively. Molecules that are labeled in both colors have dual roles. (Top left) Wnt biogenesis. A lipid modification is added to Wnt ligands by Porc in the endoplasmic reticulum (ER). Wnt ligands are glycosylated in the ER and Golgi and require Wls (also known as Evi) to traffic through the Golg...
متن کاملDirect Targeting of β-Catenin by a Small Molecule Stimulates Proteasomal Degradation and Suppresses Oncogenic Wnt/β-Catenin Signaling.
The Wnt/β-catenin signaling pathway plays a major role in tissue homeostasis, and its dysregulation can lead to various human diseases. Aberrant activation of β-catenin is oncogenic and is a critical driver in the development and progression of human cancers. Despite the significant potential of targeting the oncogenic β-catenin pathway for cancer therapy, the development of specific inhibitors...
