How Vincristine works
Vincristine is an anti-cancer chemotherapy medication.
It works by interfering with cell division. It binds to tubulin, preventing the proper formation of microtubules, interfering with the creation of the mitotic spindle, and stopping cells from dividing.
It also inhibits the synthesis of DNA and RNA, which are essential for cell growth and reproduction. As a result, abnormally dividing cancer cells undergo programmed cell death.
