Cytoskeletal activity
WebCell migration requires the coordination of an excitable signal transduction network involving Ras and PI3K pathways with cytoskeletal activity. We show that expressing activated Ras GTPase-family proteins in cells lacking PTEN or other mutations which increase cellular protrusiveness transforms cells into a persistently activated state. WebOct 30, 2024 · The cytoskeleton can be described as semiflexible polymers [ 61] composed of enthropic (filament entanglement) and enthalpic (intramolecular interactions) components [ 62, 63 ]. The cytoskeleton shows nonlinear stress stiffening, followed by stress softening at high stresses which is completely reversible [ 64 ].

WebMar 20, 2024 · p27 kip1 (p27) is an inhibitor of cyclin/cyclin-dependent kinase complexes, whose nuclear loss indicates a poor prognosis in various solid tumors. When located in the cytoplasm, p27 binds Op18/stathmin (stathmin), a microtubule (MT)-destabilizing protein, and restrains its activity. This leads to MT stabilization, which negatively affects cell …
