Our Focus

 

The first aim of our group is to unravel the mechanisms that protect genetic integrity of a normal cell, and study how these mechanisms are compromised in cancer cells to allow them to evolve more rapidly. This capacity to rapidly evolve comes at a cost of having to adapt to a new genetic make-up, sometimes involves gains or losses of entire chromosomes, and we are very interested to understand how cells manage to adapt to this type of instability. This has allowed us to uncover several liabilities that can be exploited to target cancer cells, some of which are currently being tested clinically. 
 

Since our move to the Princess Maxima Center in 2024 and the merger of my group with the group of Gerben Vader, we have (further) developed 2 new research lines relevant to pediatric cancer. In the first we study the role of ecDNA, prominently present in various forms of difficult-to-treat pediatric cancers and try to identify liabilities of ecDNA-containing cancers. In the second, we try to identify germ line-specific proteins that are expressed in pediatric cancers, as a means to identify proteins that can discriminate pediatric cancer cells from other somatic cells. 

About René Medema

My Research

Rene H. Medema started his career in 1989 in the lab of Hans Bos in Leiden as a PhD student working on signal transduction by p21ras. After his PhD he moved to the laboratory of Prof. Dr. R.A. Weinberg (Whitehead Institute, Cambridge, MA) for his postdoctoral training, working on cell cycle control. As an independent group leader he continued to study cell cycle control, first at the University Medical Center Utrecht (1995-2000) and subsequently at the Netherlands Cancer Institute (2001-2005). In 2005 he moved back to Utrecht to become professor in Experimental Oncology. In 2012, he was appointed director of research at the Netherlands Cancer Institute.

His group has made several key contributions to the general understanding of control of the cell cycle by Forkhead transcription factors, FoxO and FoxM1. In addition, work from his group has provided more insight on the role of motor proteins in spindle assembly and the consequences of chromosome missegregation on the genomic stability and viability of a tumor cell. His group was the first to show that recovery from a DNA damage-induced arrest is controlled by Polo-like kinase-1 in 2004, and his lab has since provided several major contributions to our understanding of the recovery process.
