The objective of this study was to investigate the expression and function of GRHL2 in different breast cancer subtypes.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

In this research group, headed by Prof. Erik Danen, the aim is to unravel cellular signaling mechanisms in normal and diseased cells, with a long-standing interest in cell adhesion signaling. In complex multicellular organisms such as ourselves, a division of labor emerges where different tissues and…

With cancer, a person’s body cells grow uncontrollably. Putting together a detailed picture of how this comes about makes it possible to develop efficient therapies. Researchers at the Leiden University Medical Centre (LUMC) and Leiden University are working together to gain a better understanding…

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

Some people are predisposed to develop cancer. Mutations in genetic material that increase a person’s chances of developing cancer can already be present at birth. Researchers are closely examining these mutations to learn more about how cancer begins to develop.

The spindle-assembly checkpoint (SAC) is a safety mechanism which secures accurate chromosome segregation during mitosis.

Cancer represents a formidable current and future global health challenge. The LUMC medical research profile Cancer Pathogenesis and Therapy charges this challenge by developing and implementing innovative patient-tailored, multimodal diagnostic methods and treatment modalities.

Breast cancer is the most common cancer in women worldwide. Metastasis, the process by which cancer cells spread to other parts of the body, makes treatments less effective. It is important to unravel the mechanism of metastasis.

Can the conditioning paradigm be used for checkpoint inhibition cancer treatment?

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

To improve treatment of breast cancer patients it is important to understand all stages of breast cancer from initiation to in situ disease and progression to invasive disease. In this thesis we use intraductal injections of patient derived tissue to model ductal carcinoma in situ and invasive breast…

What distinguishes a tumour cell from a healthy cell? Researchers are trying to answer this question as precisely as possible. Certain differences could eventually lead to new therapies.

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

Breast cancer (BC) is a clinically and biologically heterogeneous disease.

Drug development is hampered by the limited predictive value of conventional 2D culture systems, which fail to recapitulate the complexity of the disease microenvironment and contribute to high clinical attrition rates.

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

In the hunt for a vaccine against cervical cancer, fundamental knowledge about the immune system and organic chemistry have been brought together and have already resulted in a vaccine that is now being tested in clinical trials. Scientists are now working hard on an improved variant.

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…

In this thesis, we will utilize embryonic zebrafish tumour models to understand the interaction between engrafted human cancer cells and macrophages from the host, test drug administration modalities and anti-cancer efficacies of newly-developed PDT and PACT compounds, and test a light-triggered liposomal…

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by limited treatment options and unfavorable clinical outcomes. Therefore, the research described in this thesis focused on the exploration of novel targeted therapies for TNBC.

Pancreatic ductal adenocarcinoma (PDAC) is among the cancers with the highest mortality rate, despite a relatively low incidence.

Triple-negative breast cancer (TNBC) constitutes a small subtype (~15%) of breast cancer, but causes the majority of breast cancer-related deaths.

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

What are the biological effects of Chinese herbal medicine in regulation of cancer cell metastasis?

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

The potential of liposomal cancer vaccines

Cancer is still one of the most common diseases in the world. What exactly is cancer and will we one day be able to cure everyone? In a video from the Universiteit van Nederland Noel de Miranda (Tumour Immunology, LUMC) tells you about his research on new treatments.

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

This thesis focuses on using liposomes in two different treatment strategies; vaccination (or immunotherapy) and delivery of a small molecule, and in two different disease models; cancer and atherosclerosis.

Zebrafish-human communication shows that cancer cells lacking a signaling protein are less able to develop aggressive metastatic properties. This discovery has been made by molecular cell biologist Claudia Tulotta. PhD defence 14 June.
