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...
متن کاملTAK1-dependent signaling requires functional interaction with TAB2/TAB3.
Transforming growth factor beta-activated kinase 1 (TAK1), a member of the MAPKKK family, was initially described to play an essential role in the transforming growth factor beta-signaling pathway, but recent evidence has emerged implicating TAK1 in the interleukin (IL)-1 and tumor necrosis factor (TNF) pathways. Notably, two homologous proteins, TAB2 and TAB3, have been identified as adaptors ...
متن کاملWnt-1 signal induces phosphorylation and degradation of c-Myb protein via TAK1, HIPK2, and NLK.
The c-myb proto-oncogene product (c-Myb) regulates both the proliferation and apoptosis of hematopoietic cells by inducing the transcription of a group of target genes. However, the biologically relevant molecular mechanisms that regulate c-Myb activity remain unclear. Here we report that c-Myb protein is phosphorylated and degraded by Wnt-1 signal via the pathway involving TAK1 (TGF-beta-activ...
متن کاملNLK-mediated phosphorylation of HDAC1 negatively regulates Wnt signaling
The Wnt signaling pathway is essential in regulating various cellular processes. Different mechanisms of inhibition for Wnt signaling have been proposed. Besides β-catenin degradation through the proteasome, nemo-like kinase (NLK) is another molecule that is known to negatively regulate Wnt signaling. However, the mechanism by which NLK mediates the inhibition of Wnt signaling was not known. In...
متن کاملTAK1-TAB2 signaling contributes to bone destruction by breast carcinoma cells.
Advanced-stage breast cancers frequently metastasize to the bones and cause bone destruction, but the underlying mechanism is not fully understood. This study presents evidence that TGF-β-activated protein kinase 1 (TAK1) signaling in tumor cells promotes bone destruction by metastatic breast carcinoma cells, controlling expression of prometastatic factors including matrix metalloproteinase (MM...
