Killing cells by targeting mitosis.

Area of Science:

• Oncology
• Cell Biology
• Cancer Therapeutics

Background:

• Cell cycle deregulation and genomic instability are hallmarks of human cancers.
• Targeting cancer cell proliferation is a key therapeutic strategy.
• Mitosis offers multiple targets for cancer cell killing.

Purpose of the Study:

• To review current therapeutic strategies targeting the cell division cycle in cancer.
• To explore novel approaches focusing on mitosis and mitotic exit.
• To highlight the potential of targeting mitotic pathways for cancer treatment.

Main Methods:

• Review of existing literature on cell cycle targeting in cancer.
• Analysis of novel strategies including kinase inhibitors and checkpoint abrogation.
• Examination of targeting mitotic exit via anaphase-promoting complex inhibition.

Main Results:

• Inhibiting initial cell cycle phases may yield quiescent cells, while targeting mitosis offers cell death possibilities.
• Microtubule poisons are clinically effective; novel targets include kinases and kinesins.
• Inhibiting mitotic exit induces metaphase cell death, suggesting a potent therapeutic window.

Conclusions:

• Targeting mitosis, especially mitotic exit, presents a promising strategy for cancer therapy.
• Further research into molecular pathways of mitotic cell death is crucial for clinical translation.
• Novel approaches like anaphase-promoting complex inhibition warrant clinical investigation.
