One of the most popular methods to visualize the overlap and differences between data sets is the Venn diagram. Venn diagrams are especially useful when they are 'area-proportional' i.e. the sizes of the circles and the overlaps correspond to the sizes of the data sets. In 2007, the BioVenn web interface was launched, which is being used by many re...

“Big data” is a term that has been used often in the past decade to describe datasets that are extremely large and complex so that traditional software is unable to store and analyze them in an accurate way. It can refer to “long data,” “wide data,” and both. Big data is of increasing importance in healthcare as well: new methods dedicated to impro...

In recent years, more and more health data are being generated. These data come not only from professional health systems, but also from wearable devices. All these 'big data' put together can be utilized to optimize treatments for each unique patient ('precision medicine'). For this to be possible, it is necessary that hospitals, academia and indu...

Translational research applies findings from basic science to enhance human health and well-being. In translational research projects, academia and industry work together to improve healthcare, often through public-private partnerships. This “translation” is often not easy, because it means that the so-called “valley of death” will need to be cross...

The orientation of closely linked genes in mammalian genomes is not random: there are more head-to-head (h2h) gene pairs than expected. To understand the origin of this enrichment in h2h gene pairs, we have analyzed the phylogenetic distribution of gene pairs separated by less than 600 bp of intergenic DNA (gene duos). We show here that a lack of h...

The transfer of functional annotations from model organism proteins to human proteins is one of the main applications of comparative genomics. Various methods are used to analyze cross-species orthologous relationships according to an operational definition of orthology. Often the definition of orthology is incorrectly interpreted as a prediction o...

Many G protein-coupled receptor (GPCR) models have been built over the years. The release of the structure of bovine rhodopsin in August 2000 enabled us to analyze models built before that period to learn more about the models we build today. We conclude that the GPCR modelling field is riddled with 'common knowledge' similar to Lord Kelvin's remar...

The immune system is of major importance since it protects metazoans from infection by pathogenic organisms. Throughout evolution, two major branches have originated: innate and adaptive immunity. The innate immune system exists in a wide range of metazoans, whereas the adaptive immune system is only present in jawed vertebrates. Both the innate an...

Prostate cancer (PCa) is the most common malignancy in Western men. When localised within the prostate, the tumour can be treated by radiotherapy or surgical removal of the prostate. However, a substantial number of patients suffer relapse due to metastatic tumours that can only be treated by palliative therapy. The Prostate Cancer Molecular Medicine (PCMM) project will address two major clinical needs. Firstly, the need to reduce overdiagnosis and overtreatment of prostate cancer due to today’s less than ideal screening tests (PSA tests). Secondly, the need for better therapy monitoring techniques for advanced disease. To improve overdiagnosis, the project will attempt to develop and validate novel biomarkers in blood, urine and tissue that can be used to differentially diagnose and evaluate prognosis for individual patients, and that can also be applied for tailored treatment. To improve therapy monitoring for metastatic tumours, it will develop and test innovative imaging tools that can be used to visualise and evaluate early response to treatment, allowing therapy management at the level of the individual patient. The biomarker and imaging studies in PCMM will be facilitated by a unique Dutch prospective biobank composed of biological specimens and imaging data from patients with various stages of prostate cancer. An IT infrastructure will be designed that allows for the integration of clinical and research data in a central database.
