WebOur candidate tumor suppressor p38 as well as its downstream targets such as phosphorylation of mTOR, actin remodeling and autophagy can be modulated with pharmacologically available small molecules such as anisomycin, rapamycin, hydroxychloroquine and cytochalasin. WebAbstract: Cytochalasin D (CD) has been extensively used for assessing the role of the actin cytoskeleton in different biological processes. However, effects of CD have not …
WebIn 0.5 mM MgCl2, cytochalasin D uncoupled the actin ATPase activity from actin polymerization, increasing the ATPase rate by at least 20 times while inhibiting … As cytochalasin B inhibits actin filament polymerization, many cellular processes depending on actin filament functions are affected. Cytokinesis is inhibited, however, mitosis is unaffected. Due to the effects on several cellular functions but lack of general toxicity, cytochalasin B is applied in actin polymerization studies, cell imaging methods, cell cycle studies and can possibly be used as anticancer drug.
WebNov 22, 2024 · We observed that the perturbation of actin with cytochalasin D or via Fmn2 knockout caused a significant increase in misaligned chromosomes in meiosis II metaphase, and lagging chromosomes during both meiosis I and meiosis II anaphase. Furthermore, acute addition of cytochalasin D to oocytes with chromosomes already aligned at the … WebCytochalasin D is a cell-permeable mycotoxin that binds to the barbed end of actin filaments inhibiting both the association and dissociation of subunits. It causes the disruption of actin filaments and inhibition of actin polymerization. As a result, it impedes with a variety of processes including cell cycle, motility, phagocytosis ...
WebGeneral description. Cytochalasin B is a cell-permeable fungal toxin / mycotoxin that binds to the ′barbed′ end of actin / actin filaments. This binding leads to: Disruption of actin filaments and of interaction of actin filaments in solution. Inhibition of actin polymerization. Inhibition of subunit association and dissociation.
