Microtubules as a target for anticancer drugs
Highly dynamic mitotic-spindle microtubules are among the most successful targets for anticancer therapy. Microtubule-targeted drugs, including paclitaxel and Vinca alkaloids, were previouslyExpand
Mechanism of mitotic block and inhibition of cell proliferation by taxol at low concentrations.
Taxol inhibited HeLa cell proliferation by inducing a sustained mitotic block at the metaphase/anaphase boundary. Half-maximal inhibition of cell proliferation occurred at 8 nM taxol, and mitosis wasExpand
Mammalian mad2 and bub1/bubR1 recognize distinct spindle-attachment and kinetochore-tension checkpoints
Metaphase checkpoint controls sense abnormalities of chromosome alignment during mitosis and prevent progression to anaphase until proper alignment has been attained. A number of proteins, includingExpand
Effects of vinblastine, podophyllotoxin and nocodazole on mitotic spindles. Implications for the role of microtubule dynamics in mitosis.
Inhibition of mitosis by many drugs that bind to tubulin has been attributed to depolymerization of microtubules. However, we found previously that low concentrations of vinblastine and vincristineExpand
Mitotic block induced in HeLa cells by low concentrations of paclitaxel (Taxol) results in abnormal mitotic exit and apoptotic cell death.
Paclitaxel at low concentrations (10 nM for 20 h) induces approximately 90% mitotic block at the metaphase/anaphase transition in HeLa cells, apparently by suppressing dynamics of spindleExpand
Substoichiometric binding of taxol suppresses microtubule dynamics.
We have measured the effects of taxol (10 nM to 1 microM) on the growing and shortening dynamics at the ends of individual bovine brain microtubules in vitro and have correlated the effects both withExpand
Microtubules and actin filaments: dynamic targets for cancer chemotherapy.
Microtubules and actin filaments play important roles in mitosis, cell signaling, and motility. Thus these cytoskeletal filaments are the targets of a growing number of anti-cancer drugs. In thisExpand
Microtubule dynamics in vitro are regulated by the tubulin isotype composition.
The growing and shortening dynamics of individual bovine brain microtubules at their plus ends at steady state in vitro, assembled from isotypically pure alpha beta II, alpha beta III, or alpha betaExpand
Functional interactions between the proline-rich and repeat regions of tau enhance microtubule binding and assembly.
Tau is a neuronal microtubule-associated protein that promotes microtubule assembly, stability, and bundling in axons. Two distinct regions of tau are important for the tau-microtubule interaction, aExpand
Inhibition of DNA decatenation, but not DNA damage, arrests cells at metaphase.
DNA damage by double-strand breaks induces arrest during interphase in mammalian cells. It is not clear whether DNA damage can arrest cells in mitosis. We show here that three human cell lines, HeLa,Expand
