Question

a mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. why would these be helpful in tumor treatments?

Answer 1

cancerous cells(in tumors) are in a phase of rapid mitosis(they don’t pass the whole G phase and just divide rapidly).

So mitosis inhibitors would inhibit this rapid division and the further growth of the tumor and progression of cancer in the patient.

Answer 2

Mitosis inhibitor prevents tumor cells to enter mitosis by disrupting microtubules polymerization and stop it dividing.

Explanation:

Cancer cells are cells that undergo the mitotic division and bypass the G phase and divide rapidly. Mitotic cell division occurs in somatic cells that result in two identical daughter cells.

During mitotic cell division, there are different checkpoints that control different aspects and prevent a cell to divide rapidly.

Mitotic inhibitors are chemicals or agents that inhibit proteins that prevent a tumor cell to undergo in the mitotic division. Such agents inhibit a protein that forms microtubules polymerization.
