Gene expression control in cancer and trisomy 21

Project Description

Our main research goal is to understand how gene networks control cell behavior. Cancer is our core paradigm, but our discoveries often lead us into other areas of biology. We define cancer as a disease of gene networks gone awry. Our research focuses on the molecular mechanisms by which cancer-relevant genes regulate the networks in which they are embedded. We believe that this type of basic research is a requisite step in the development of effective cancer therapeutics. This field is broad with many important questions, which inspires us to constantly expand our repertoire of approaches and technologies to find answers.
Much of our research enterprise focuses on the p53 gene network. p53 is the most commonly mutated gene in human cancer and our research may enable effective cancer therapies. We also study other cancer genes, such as the oncogenes CDK8, HIF1A and p63.
More recently, we started to investigate the molecular, cellular and organismal effects of trisomy 21, the genetic condition that causes Down syndrome. In particular, we are interested in elucidating how trisomy 21 causes a different disease spectrum in the population with Down syndrome, protecting these individuals from some conditions (e.g. solid tumors) while predisposing them to others (e.g. Alzheimer's disease).
