Control of cell polarity by noncanonical Wnt signaling in C. elegans.
نویسنده
چکیده
The three Caenorhabditis elegans beta-catenin each function in distinct processes: BAR-1 in canonical Wnt signaling that controls cell fates and cell migrations, HMP-2 in cell adhesion and WRM-1 in Wnt signaling pathways that function in conjunction with a mitogen-activated kinase (MAPK) pathway to control the orientations, or cell polarities, of cells that undergo asymmetric cell divisions. In addition, WRM-1 does not interact with the canonical beta-catenin binding site in POP-1/Tcf. Thus, Wnt signaling through WRM-1 is noncanonical and, except for one division that might not include any of the three C. elegans beta-catenin, controls cell polarity in C. elegans.

Interaction of viral oncogenic proteins with the Wnt signaling pathway
It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...
متن کاملNoncanonical Wnt signaling pathways in C. elegans converge on POP-1/TCF and control cell polarity.
In the nematode Caenorhabditis elegans, a canonical Wnt signaling pathway controls a cell migration whereas noncanonical Wnt pathways control the polarities of individual cells. Despite the differences in the identities and interactions among canonical and noncanonical Wnt pathway components, as well as the processes they regulate, almost all C. elegans Wnt pathways involve the sole Tcf homolog...
متن کاملWnt signaling.
The use of Wnt ligands for signaling between cells is a conserved feature of metazoan development. Activation of Wnt signal transduction pathways upon ligand binding can regulate diverse processes including cell proliferation, migration, polarity, differentiation and axon outgrowth. A 'canonical' Wnt signaling pathway has been elucidated in vertebrate and invertebrate model systems. In the cano...
متن کاملA novel noncanonical Wnt pathway is involved in the regulation of the asymmetric B cell division in C. elegans.
The polarities of several cells that divide asymmetrically during Caenorhabditis elegans development are controlled by Wnt signaling. LIN-44/Wnt and LIN-17/Fz control the polarities of cells in the tail of developing C. elegans larvae, including the male-specific blast cell, B, that divides asymmetrically to generate a larger anterior daughter and a smaller posterior daughter. We determined tha...
متن کاملAdvocating Asymmetry and the POP-1 Paradox: Noncanonical Wnt Signaling in C. elegans
In this issue of Cell, Kidd and colleagues (Kidd et al., 2005) describe their identification of a novel beta-catenin that functions in noncanonical C. elegans Wnt signaling pathways to specify the different fates of daughter cells produced by asymmetric cell division.
