WebJun 8, 2024 · Inhibition of the NMMHC IIA-actin interaction using blebbistatin and the F-actin polymerization inhibitor cytochalasin D significantly suppressed ATG9A trafficking and autophagy induction. Furthermore, blebbistatin significantly improved neurological deficits and infarct volume after ischemic attack in mice, accompanied by ATG9A … 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]

WebApr 13, 2024 · A titration of the actin polymerisation inhibitor, Cytochalasin D (CytD) (A), and actin polymerisation stabiliser, Jasplakinolide (B), were tested against the MMV291-resistant lines and 3D7 parasites in a 72-hour growth assay. This revealed that MMV291-resistant parasites did not exhibit cross resistance to CytD and Jasplakinolide, indicating ... 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 ...
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: [noun] any of a group of metabolites isolated from fungi (especially Helminthosporium dematioideum) that inhibit various cell processes.
