The concentration of taxol that suppressed dynamics in interphase cells was also found to inhibit cell proliferation and block mitosis by preventing progression from metaphase to anaphase.
What phase of the cell cycle does taxol affect?
Paclitaxel (taxol) is a chemotherapeutic agent frequently used in combination with other anti-neoplastic drugs. It is most effective during the M phase of the cell-cycle and tends to cause synchronization in malignant cells lines.
Does taxol block mitosis?
At its lowest effective concentrations, taxol appears to block mitosis by kinetically stabilizing spindle microtubules and not by changing the mass of polymerized microtubules.
What specific stage of mitosis is inhibited by the chemotherapy drug taxol?
Taxol is an anti-mitotic agent that binds to microtubules and stabilizes them against depolymerization; therefore, Taxol inhibits cell replication by disrupting normal mitotic spindle formation and arresting cell growth in the M phase of the cell cycle [12-14].
What does taxol do in anaphase?
Taxol promotes the formation of abundant new microtubules and lateral association within and between microtubule arrays (spindle fibers). This leads to a pronounced reorganization of the spindle, especially at the polar regions.
Why is Taxol given weekly?
Weekly paclitaxel after standard adjuvant chemotherapy with doxorubicin and cyclophosphamide improves disease-free and overall survival in women with breast cancer.
How effective is Taxol?
Nevertheless, response rates with weekly paclitaxel up to 86% have been achieved with single-agent therapy, up to 87% with combination therapy and up to 100% when combined with radiotherapy.
Why is Taxol an effective anticancer drug?
Taxol, an antimitotic agent used to treat cancer, blocks cancer cell growth by stopping cell division, resulting in cell death.
Does Taxol shrink tumors?
Thankfully, I had a lot of help from family. The tumor didn’t shrink all that much with AC, but my onc said that some tumors respond better to Taxol, so I remained hopeful. After the second dose of Taxol, it was apparent that Taxol wasn’t effective either. The tumor was “softening” they said, but no shrinkage.
Why is Taxol toxic?
Neurotoxicity, manifested primarily by a motor and sensory polyneuropathy, is the principal nonhematological side effect of Taxol. Available evidence suggests that Taxol produces a toxic effect involving either axons or ganglion cell bodies, or both, rather than a myelinopathy.
