Abstract:
Whole-genome doubling (WGD) has recently emerged as one of the most common genomic alterations in cancer and is associated with genomic instability, drug resistance, and metastasis. However, WGD also generates unique vulnerabilities that create a therapeutic window between cancer cells and healthy cells. Over the past few years, there has been a rapid growth in our understanding of WGD at a molecular level. In this review, we discuss the causes and immediate cellular effects of, and therapeutic considerations for, WGD in cancer.
