Mitotic and mitogenic Wnt signalling.
Canonical Wnt signalling plays an important role in development, tissue homeostasis, and cancer. At the cellular level, canonical Wnt signalling acts by regulating cell fate, cell growth, and cell proliferation. With regard to proliferation, there is increasing evidence for a complex interaction between canonical Wnt signalling and the cell cycle. Mitogenic Wnt signalling regulates cell prolife...
متن کاملA genetic hierarchy establishes mitogenic signalling and mitotic competence in the renal tubules of Drosophila.
Cell proliferation in the developing renal tubules of Drosophila is strikingly patterned, occurring in two phases to generate a consistent number of tubule cells. The later phase of cell division is promoted by EGF receptor signalling from a specialised subset of tubule cells, the tip cells, which express the protease Rhomboid and are thus able to secrete the EGF ligand, Spitz. We show that the...
متن کاملWnt signalling: Antagonistic Dickkopfs
Dickkopf proteins are secreted antagonists of the Wnt cell signalling molecules, which have a novel mode of action. Dickkopf1 binds to the LRP5/6 Wnt co-receptor and prevents the formation of active Wnt--Frizzled--LRP5/6 receptor complexes, thus blocking the canonical Wnt--beta-catenin pathway.
متن کاملDishevelled, a Wnt signalling component, is involved in mitotic progression in cooperation with Plk1.
Wnt signalling is known to promote G1/S progression through the stimulation of gene expression, but whether this signalling regulates mitotic progression is not clear. Here, the function of dishevelled 2 (Dvl2), which transmits the Wnt signal, in mitosis was examined. Dvl2 localized to the spindles and spindle poles during mitosis. When cells were treated with nocodazole, Dvl2 was observed at t...
متن کاملDrugging Wnt signalling in cancer.
Aberrant regulation of the Wnt signalling pathway has emerged as a prevalent theme in cancer biology. This chapter summarizes the research that provides a proof of concept for inhibiting Wnt signalling in cancer, the potential means by which this could be achieved, and some recent advances towards this goal. A brief discussion of molecular diagnostics and possible safety concerns is also provided.
