Targeting chromosomal instability and aneuploidy in cancer

Area of Science:

• Oncology
• Genetics
• Cancer Biology

Background:

• Chromosomal instability (CIN) and aneuploidy are key drivers of cancer development and therapeutic resistance.
• Previous technical limitations have hindered the targeting of CIN and aneuploidy in cancer treatment.
• Recent advancements have expanded the tools for studying aneuploidy in cellular models.

Purpose of the Study:

• To review recent developments in understanding and targeting CIN and aneuploidy in cancer.
• To highlight new discoveries linking specific aneuploidies to drug-targetable vulnerabilities.
• To explore the potential of conventional antimitotic drugs in inducing CIN for therapeutic benefit.

Main Methods:

• Review of recent literature on CIN, aneuploidy, and cancer therapeutics.
• Analysis of evidence suggesting antimitotic drugs induce CIN.
• Identification of potential drug-targetable chromosome arm aneuploidies (CAAs).

Main Results:

• Accumulating evidence indicates seven conventional antimitotic drugs exert clinical response by inducing CIN.
• Discovery of 25 specific chromosome arm aneuploidies (CAAs) as potential therapeutic targets.
• Identification of 36 drugs that may target these CAAs across 14 cancer types.

Conclusions:

• Recent advances provide new opportunities for targeting CIN and aneuploidy in cancer.
• Conventional antimitotic drugs may offer a viable strategy for inducing therapeutic CIN.
• Targeting specific CAAs with existing drugs presents a promising avenue for improving cancer treatment outcomes.
