How does the drug vinblastine affect mitosis?
How does the drug vinblastine affect mitosis?
Both vincristine and vinblastine bind to the microtubular proteins of the mitotic spindle and prevent cell division during the anaphase of mitosis. They arrest mitosis and cause cell death. The drugs are therefore M-phase cell-cycle specific and their effects are therefore limited to dividing cells.
What happens to cancer cells when given vinblastine?
Vinblastine works by stopping the cancer cells from separating into 2 new cells. So it blocks the growth of the cancer.
