Cytochalasin d concentration
WebApr 7, 2024 · The use of Cytochalasin D, a specific inhibitor of actin polymerization, has demonstrated that actin cytoskeleton depolymerization may play an important role in mechanical stress-induced interleukin expression and c-jun N-terminal kinase (JNK) phosphorylation levels in various types of cells [ 12 – 14 ]. WebJan 7, 2015 · The antitumor effects of cytochalasin B were mirrored by cytochalasin D at much lower concentrations (Fig. 6b). It only took 2 mg/kg/day cytochalasin D administered for eight consecutive days (Days 1–8) to produce marked prolongation in the life expectancy of mice challenged with P388/S, as well as a 20 % long-term survival rate.

WebFeb 21, 2024 · In some wells, cytochalasin D (10 μM, Thermo Fisher Scientific) was added to inhibit phagocytosis. Image analysis was performed using Columbus™ (Perkin Elmer). Hoechst 33342-stained nuclei were detected. The cytoplasm around each nucleus was identified and the pHrodo green-positive spots within this region were detected. WebOn the other hand, cytochalasin-D is an inhibitor of the F-actin polymerization process, making it unable to form proper actin filaments [7,8]. The higher the concentration of Blebbistatin, Cytochalasin-D or both, the more wound closure and migration speed were decreased due to inhibition of the actin cytoskeleton.
WebJul 20, 2012 · In this study, cytochalasin D (CytoD), a widely used inhibitor of actin dynamics, was found to act as an inhibitor of the G-actin-cofilin interaction by binding to G-actin. CytoD also inhibited the binding of cofilin to F-actin and decreased the rate of both actin polymerization and depolymerization in living cells. Webconcentration increases with cytochalasin D up to 12- fold its value when both ends are free; as a result of the lowering of the free energy of nucleation by cyto- chalasin D, short oligomers of F-actin exist just above and below the critical concentration. Cytochalasin D interacts strongly with the barbed ends independently
