Intranuclear Actin Regulates Osteogenesis

WebCytochalasins comprise a group of about 20 known compounds derived from molds, which affect actin stress fibers, causing rapid actin depolymerization. Cytochalasins bind to the growing end of F-actin, inhibit polymerization without affecting depolymerization, and cause disassembly of actin fibers. WebCytochalasin D is a cell-permeable and potent inhibitor of actin polymerization. It disrupts actin microfilaments and activates the p53-dependent pathways causing arrest of the cell cycle at the G1-S transition. It is believed to bind to F-actin polymer and prevent polymerization of actin monomers. [1] References [ edit] Web6.4 Association of F-actin cortex with ion channels involved in exocytosis. A number of studies suggest that actin filaments may modulate the activity of a range of ion channels. For example, cytochalasin D alters the ion flux associated with calcium channels (Johnson and Byerly, 1993) and voltage-dependent sodium channels (Cantiello et al., 1991). durham writing desk room
