Cancer is the leading cause of death in the Netherlands, and, with over 100 different types of cancer, it’s not a simple disease. Today, skin, breast, lung, prostate and colon cancer are the most diagnosed forms. Therefore, the discovery and development of new drugs has the ability to significantly improve the life span and quality of life for many cancer patients and their families.

At LED3, we have many internal and external collaborations to pursue these new treatments. LED3 members Profs. Heitman and Van der Stelt are also member of Oncode Institute, and they work together with biotech companies such as NTRC and Pivot Park Screening Center. These collaborations are aimed at identifying and optimizing novel molecules and probes to visualize and modulate kinases, GPCRs and lipid signaling in cancer cells and tumor associated immune cells. 

Furthermore, we have performed several high throughput screenings campaigns and executed multiple hit- and lead optimization programs for acute myeloid leukemia and triple negative breast cancer in collaboration with the Leiden University Medical Center, Netherlands Cancer Institute and Hubrecht Institute. Finally, within LED3 we are developing and applying novel machine learning and chemical proteomic methods for the profiling of on-target and off-target activities of leads in cancer cells [1-3].
