Bacterial Chromatin
The relative simplicity of the bacterial cell, short generation times and well defined and inexpensive culturing conditions have significantly contributed to our understanding of many complex biological systems. Yet the workings of the bacterial genome, seemingly impossibly compressed within a tiny…

From wolf to dog
Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

Metabolomics assisted with stable-isotope labeling: exploring neuronal metabolism related to Parkinson’s disease
The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

The Role of Linker DNA in Chromatin Fibers
The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

ACTION
Aggression inflicts a huge personal, psychological and financial burden on affected individuals, their relatives, and society at large. Despite large scientific, preventive, and treatment investments, no decrease in aggressive behaviour is seen. By combining interdisciplinary expertise the ACTION consortium…

Train your brain!
Neuroimaging research has greatly advanced our insights on how the brain is organized. Now is the time for the next step: Imagine what would be possible when we cannot only map brain-functioning, but use neuroimaging to voluntarily regulate brain-activity!

Prior information and variational Bayes in high dimensional statistical network inference
This thesis develops statistical methods for the analysis of high dimensional data: high dimensional networks reconstruction (Chapters 1-4), incorporation of prior information in networks reconstruction (Chapters 2-4), incorporation of prior knowledge in genetic association studies (Chapter 3).

Contact-induced change in Dolgan
This study explores the role of linguistic data in the reconstruction of Dolgan (pre)history by analyzing contact-induced changes and using them to infer information about the nature of the contact settings in which they occurred.

Evolution and development of flowers, fruits and inflorescences of Phalaenopsis and other orchid species
The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Nucleosome stacking in chromatin fibers probed with single-molecule force- and torque-spectroscopy
In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

Regulation of actomyosin contraction as a driving force of invasive lobular breast cancer
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).

Spatial populations with seed-bank
In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

Finding and valorizing new antibiotics using AI
Antibiotics are a class of medicine most people take for granted. But pathogenic bacteria are becoming more and more resistant to our antibiotics, and this poses a great challenge for future treatments. There is thus a great societal need to identify new molecules that can address new targets and be…

Unravelling East Africa’s Early Linguistic History (LHEAf)
This project investigates the rich linguistic history of the crucial language groups in East Africa and includes a search for words that indicate earlier lost languages. These outcomes, combined with recent archaeological and genetic research, will contribute to a new understanding of East Africa’s…

Mechanisms and consequences of horizontal gene transfer in cell wall-deficient cells of Kitasatospora viridifaciens
The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Highly sensitive analysis using 3D cell culture model
A research goal for ABS is to develop miniaturized platforms for research in (stem)cell, in-vitro systems and application in clinical and preventive research. Combined with the high throughput, this development will make it possible to study the dynamics of pathogenesis in human and cellular models…

Inhibitor discovery of phospholipases and N-acyltransferases
In this thesis an activity-based probe was discovered that could visualize the activity of PLAATs. With an optimized gel-based ABPP assay in hand, screening of a compound library led to the discovery of alpha-ketoamides as a hit for PLAAT3.

Arabidopsis AGC3 kinases and PIN plasma membrane abundance
The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

Neandertal Legacy
The genetic material of currently living Europeans is partly of Neandertal origin. Were our ancestors successful because they were hybridising and interacting with the local populations they encountered when migrating into new places? Reconstructing our evolutionary trajectory is key for rethinking…

Searching for the concrete subject: On the epistemic role of lived-experience in Paul Natorp's critical epistemology
The following dissertation reconstructs Paul Natorp's philosophical psychology. It argues that psychology's main object is the lived experience of concrete subjects, understood as a transcendental structure of logical-reflexive conditions for the recognition, appropriation, and evaluation of objective…
