How does invasive hybridization affect threatened native species?

In the master’s specialisation Molecular Genetics and Biotechnology at Leiden University students are trained by experts in the areas of molecular biology, microbiology, plant genetics, cellular imaging, animal disease models, and various –omics technologies and the corresponding bioinformatics.

Investigating neurobiological endophenotypes of Social Anxiety Disorder

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

Are traces of fire use detectable in ancient hominin genomes?

This study analyses the prehistory of a northeastern Siberian population, the Sakha, from both a molecular-genetic and a linguistic perspective.

In this thesis, I investigated the neurogenetic properties of Neotropical bat species. Bats represent the second largest mammalian order (Chiroptera) in the world, with Neotropical bats constituting about 13% of the total number of bat species.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

How do genetic and environmental factors make us vulnerable to depression?

The applications of studying the early development of insects range from agriculture to material science.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

Chemical tools to monitor drug-target engagement of endogenously expressed protein kinases are highly desirable for preclinical target validation in drug discovery. Here, we describe a chemical genetics strategy to selectively study target engagement of endogenous kinases.

This thesis investigates how non-genetic factors, such as inflammation and concomitant medication, impact hepatic drug metabolism and subsequent drug metabolizing phenotype predictions.

Starting from Husserl’s somewhat controversial claim about the immortality of the constituting subjectivity, this thesis uses the limit-case of death in order to present a phenomenological exploration of the notion of subjectivity and its relationship to nature. It also offers a second-order discussion…

Human measures to protect lions have an impact on the genetic health of populations. Leiden and Kenyan scientists discovered this by analysing the DNA of 171 Kenyan lions. ‘By fencing reserves, for example, the chance of inbreeding increases.’ With the knowledge and tools from the research, management…

In an innovative study, Radboudumc and LUMC jointly tested a candidate vaccine based on a genetically weakened malaria parasite. The results of this clinical trial, published in Science Translational Medicine, show that the vaccine is safe and elicits a defense response against a malaria infection.

It was already known that social anxiety disorder often affects more than one person in the same family. But research by PhD student Janna Marie Bas-Hoogendam has now shown that there are genetic brain characteristics that are associated with social anxiety. The PhD ceremony will take place on 14 Ja…

Despite their ecological, cultural, and economic importance, lion (Panthera leo) populations in Kenya are declining rapidly due to retaliatory killings following livestock depredation, depletion of wild prey, habitat loss driven by human activities, climate change, and disease.

A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

Remko Offringa has been appointed Professor in the field of Plant Developmental Genetics within the Faculty of Science at the Institute of Biology Leiden (IBL) from the 1st of April 2017. Offringa’s research focuses on the role of the plant hormone auxin in controlling plant growth and development,…

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

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

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.
