With a Vici grant of 1.5 million euros, Professor of Mathematical biology Roeland Merks will look for ways to fix messy and leaky blood vessels in tumours. His research combines mathematical simulations and lab experiments in a unique way.

Researchers from Leiden University Medical Center (LUMC) and Netherlands Cancer Institute (NKI) have discovered how specialised immune cells can detect and remove cancers that are ‘invisible’ to the conventional defence mechanisms of the immune system. Their work has been published in Nature. The findings…

Leiden biophysicist Stefano Coppola has received the prestigious AXA Research Fund postdoctoral fellowship. With this grant he can work for two years on a project to research the role of mechanical factors in the development of pancreatic cancer.

As of April 1, 2018, Erik Danen has been appointed as Professor of Cancer drug target discovery at the Leiden Academic Centre for Drug Research (LACDR). His discipline is cell biology of cancer, in which he focuses on the mechanisms underlying metastasis and therapy resistance.

To inhibit proteins that contribute to the growth of aggressive cancer cells, that’s the plan of Professor Bob van de Water and his team. They will receive over 700,000 euros from the KWF Dutch Cancer Society for their research. Researcher Maaike Vreeswijk and pathologist Danielle Cohen are affiliated…

Chemist Gerjan de Bruin has designed a method of slowing down the degradation process of proteins in cells. This may contribute to new cancer medicines with fewer side-effects. PhD defence on 1 June.

Death in all types of melanomas is generally caused by metastasis. Uveal melanoma (UM) is the most common intraocular melanoma, there are currently no (patient-derived) animal models that faithfully recapitulate metastatic dissemination of UM.

Researchers of the Leiden University Medical Centre (LUMC) and the Leiden Institute of Chemistry have made an important discovery about the commonly used anti-cancer drug doxorubicin. They have found a way to reduce its side effects without sacrificing the effectiveness of the medication. This is encouraging…

The goal of the research presented in this thesis was to explore the chemical space of ruthenium(II) photocages, investigate their ability to host potent chemotherapy drugs, and to red shift the activation wavelength of the most promising PACT candidates to conduct biological studies.

How do you know if a drug will actually work? The Leiden-based spin-off Omivera is developing a new technology that could provide clearer answers. The young company received a seed investment from the investment fund UNIIQ to support its development.

This thesis seeks to investigate how cancer-associated mutations affect the pharmacological properties of selected GPCRs—primarily A2AAR and 5-HT2CR—through a combination of ligand binding assays, signaling readouts, kinetic profiling, and cellular functional assays.

The aim of this thesis was to develop novel treatment strategies for different types of eye melanoma utilizing zebrafish models. We first establish orthotopic and ectopic xenograft models for uveal and conjunctival melanoma by engraftment of the immortalized cells derived from these tumors into zebrafish…

This thesis represents a comprehensive investigation into the control of cancer stemness and metastatic initiation using a combination of advanced zebrafish xenograft models and in vitro assays.

Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

The main goal of the research described in this thesis was the development of new photoactivated chemotherapy (PACT) ruthenium(II) complexes bearing a non-toxic photolabile ligand.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

Late in 2015 a woman gave birth to a baby conceived following the reimplantation of thawed ovarian tissue. The woman was able to become pregnant thanks to transplantation of the tissue that took place in the LUMC.

Epithelial-mesenchymal plasticity (EMP) and tumor cell migration play an important role in cancer progression, and an improved understanding of the mechanisms underlying these concepts is essential for developing new targeted approaches.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

Researchers at Leiden University have demonstrated that tumours can apply mechanical means to attract the blood vessels they need to be able to grow. The team published this discovery on 2 March in Nature Scientific Reports.
