We are rapidly demystifying cancers, exposing the molecular mechanisms underlying tumors and leading the search for the next generation of targeted cancer therapies. We see a future where every cancer and every patient has a cure.

Genetic changes that turn “on” cancer genes

In addition to communicating with other cells, cells also have an internal monologue—one that occurs as they regulate gene activity. Assistant Professor Jesse Dixon, Postdoctoral Fellow Zhichao Xu, and colleagues have zeroed in on the specific mechanisms that activate oncogenes—altered genes that can cause normal cells to become cancerous. Cancer can be caused by genetic mutations, yet the impact of specific types, such as structural variants that break and rejoin DNA, can vary widely. The researchers found that genetic mutation activity depends on the distance between a particular gene and the sequences that regulate the gene, as well as on the activity level of the regulatory genetic sequences involved. The work advances the ability to predict and interpret which genetic mutations found in cancer genomes are causing the disease.
