Wnt-induced proteolytic targeting.

چکیده
Misregulation of the Wnt pathway is a common route to cancer, including primary breast cancers. In this issue of Genes & Development, Miranda-Carboni and colleagues (3121-3134) demonstrate that the cyclin-dependent kinase inhibitor p27(Kip1) is ubiquitylated for proteasomal degradation in Wnt10b-induced mammary tumors exclusively by the Cul4A E3 ligase, which is strongly induced by Wnt signaling. The discovery of a new Wnt-induced proteolytic targeting system has important implications for the mechanism of Wnt-initiated tumorigenesis.

Cell Permeable Stapled Peptide Inhibitor of Wnt Signaling that Targets β-Catenin Protein-Protein Interactions.
The Wnt signaling pathway plays a critical role in cell proliferation and differentiation, thus it is often associated with diseases such as cancers. Unfortunately, although attractive, developing anti-cancer strategy targeting Wnt signaling has been challenging given that the most attractive targets are involved in protein-protein interactions (PPIs). Here, we develop a stapled peptide inhibit...
متن کاملButyrate and bioactive proteolytic form of Wnt-5a regulate colonic epithelial proliferation and spatial development
Proliferation and spatial development of colonic epithelial cells are highly regulated along the crypt vertical axis, which, when perturbed, can result in aberrant growth and carcinogenesis. In this study, two key factors were identified that have important and counterbalancing roles regulating these processes: pericrypt myofibroblast-derived Wnt-5a and the microbial metabolite butyrate. Cultur...
متن کاملEvidence for an association between Wnt-independent -catenin intracellular localization and ovarian apoptotic events in normal and PCO-induced rat ovary
The association of secreted frizzled related protein type 4 (Sfrp4) as an antagonist of Wnt mole-cules in apoptotic events has been reported previously. Moreover, its increased expression has been reported in the ovary of women with polycystic ovary (PCO). We have demonstrated in-creased Sfrp4 in PCO-induced rat ovary related to an increased number of apoptotic follicles showing nuclear ?cateni...
متن کاملWnt up your mind - intervention strategies for S100A4-induced metastasis in colon cancer.
Colon cancer is still a burden mainly due to metastasis formation. The latter is often associated with a constitutive activation of the Wnt/beta-catenin signaling pathway and high expression of the metastasis-inducing gene S100A4. We previously identified S100A4 as a transcriptional target of beta-catenin. Intervention strategies targeting Wnt/beta-catenin signaling might therefore represent pr...
متن کاملWNT-pathway components as predictive markers useful for diagnosis, prevention and therapy in inflammatory bowel disease and sporadic colorectal cancer
The key role of the Wnt/β-catenin signaling in colorectal cancer (CRC) insurgence and progression is now recognized and several therapeutic strategies targeting this pathway are currently in developing. Wnt/β-catenin signaling not only dominates the early stages of sporadic colorectal cancer (SCC), but could also represent the connection between inflammatory bowel diseases (IBD) and increased r...
