Cell biology: Divining cancer cell weaknesses

William G. Kaelin1

Top

Tumour cells tend to carry many gene mutations, but at a potential cost to their overall fitness. Studying the interactions between genes on a large scale could be a way of identifying the chinks in the tumour cell armour.

Cancer arises when the right combination of genes is mutated in a susceptible cell, much like lock tumblers falling into place. These mutations bestow various properties of malignancy upon the cell, such as independence from growth control and the ability to colonize other tissues.
