Coping with chromosomal stress

Chromosomal instability (CIN) is detrimental for cellular fitness and is a hallmark of the majority of solid tumors. How cells adjust to this instability to ensure survival is poorly understood. The lab of Christopher Campbell has now studied the long-term adaptation to CIN using yeast cells. They found that cells accumulate mutations over time that help them to alleviate the negative effects of CIN. The work is published in The EMBO Journal.
