How does taxol act on microtubules
WebOct 23, 2007 · Van Buren et al. [10] proposed that taxol might stabilize microtubules by making the protofilaments less stiff rather than by making them less curved: In both cases, the mechanical strain energy penalty for tubulin in the microtubule lattice is reduced. We have no evidence indicating that taxol softens protofilaments because our AFM images … WebAug 1, 2016 · Taxol stabilizes microtubules and prevents their depolymerization and deacetylation during cold treatment (Schiff and Horwitz, 1980; Haggarty et al., 2003). ...
