Taxol is a mitotic inhibitor: It targets rapidly growing cancer cells by getting inside them and attaching to the scaffold-like structures of the cells called microtubules. In this way, the drug prevents cancer cells from dividing. You will be monitored regularly while you are taking Taxol to assess your response to therapy.
What is taxol used to treat?
Taxol is classified as a "plant alkaloid," a "taxane" and an "antimicrotubule agent." (For more detail, see "How Taxol Works" section below). Taxol is used for the treatment of breast, ovarian, lung, bladder, prostate, melanoma, esophageal, as well as other types of solid tumor cancers.

What is the mechanism of action of Taxol?
Mechanism of action Paclitaxel-treated cells have defects in mitotic spindle assembly, chromosome segregation, and cell division. Unlike other tubulin-targeting drugs, such as colchicine, that inhibit microtubule assembly, paclitaxel stabilizes the microtubule polymer and protects it from disassembly.
How does Taxol stop cell division quizlet?
Taxol interferes with that process by inhibiting the shortening of the microtubules attached to the sister chromatids, so the chromatids do not separate and they do not move to the ends of the cells. Ultimately the cell is unable to divide.
What structure does Taxol target?
For more than 25 years, researchers have known that Taxol targets microtubules and prevents cells from dividing, which then triggers apoptosis, a cellular mechanism also referred to as programmed cell death.

How does Taxol work microtubules?
The antitumor drug Taxol stabilizes microtubules and reduces their dynamicity, promoting mitotic arrest and cell death. Upon assembly of the α/β-tubulin heterodimer, GTP bound to β-tubulin is hydrolyzed to GDP reaching a steady-state equilibrium between free tubulin dimers and microtubules.

Into your bloodstream. You have treatment through a thin short tube (a cannula) that goes into a vein in your arm each time you have treatment. Or you might have treatment through a long line: a central line, a PICC line or a portacath. These are long plastic tubes that give the drug into a large vein in your chest.
How is taxol given?

How does chemotherapy work?
Usually, the drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cells are unable to divide, they die. The faster the cells are dividing, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink.

They grow by addition of tubulin, hydrolyzing (red turns to blue) and locking into a strained position. When the tubulin cap stops growing, the strain pulls the microtubule apart in a rapid peeling motion. Chromosomes attached to a peeling microtubule are physically pulled along. Taxol prevents the compaction and straining of the microtubule, ...
What is the function of microtubules?
Scientists call this dynamic instability. The microtubules also provide a highway for transporting the cell’s organelles and other packages around the cell. Tubulin, the basic structural unit of the microtubule, is a complex of two proteins – alpha and beta tubulin.
Why do microtubules peel apart so quickly?
Once growing stops and that cap disappears , the restrained tension rips the microtubule apart.
What happens when the tubulin complex is hydrolyzed?
Once growing stops and that cap disappears, the restrained tension rips the microtubule apart. The tension is created when the tubulin complex, which has a small energy molecule called GTP (guanosine triphosphate) attached, becomes hydrolyzed and the GTP turns into GDP (guanosine diphosphate).

When Taxol Is Used
How Taxol Works
- All cells, including tumor cells, multiply by a process called mitosis, the scientific name for cell division. Taxol works as a mitotic inhibitor, targeting rapidly dividing cancer cells to prevent the tumor from growing.2 It does so by getting inside the cells and attaching to scaffold-like structures called microtubules, interfering with their function.3 Taxol can affect any of the rapidl…
