Cancer chess: molecular insights into PARP inhibitor resistance
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…

Nano shapes micro : Impacts of metallic nanoparticles on microbial communities
This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

The Ecology and Evolution of Microbial Warfare in Streptomyces
The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Volatile compounds from Actinobacteria as mediators of microbial interactions
Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Hybrid Josephson junctions and their qubit applications
A Josephson junction is a device where a thin insulating barrier or a nanostructure is placed between two superconducting leads. Such a junction is essential to superconducting qubits that store quantum information due to its anharmonic spectrum.

The development of molecular tools for investigating NAD+ metabolism and signalling
Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…

Expanding the chemical space of antibiotics produced by Paenibacillus and Streptomyces
Antibiotic-resistant bacteria pose a major health threat. Addressing this challenge requires among others the development of new antibacterial compounds. The research described in this thesis focuses on discovering novel antibiotics from soil bacteria, specifically Streptomyces and Paenibacillus.Despite…

Beter inzicht in concurrentiestrijd tussen microben in bodems en oceanen
Vooral neerslag en bodemzuurgraad bepalen welke microben in een bepaalde habitat overleven en welke niet. Deze kennis is van belang om de biodiversiteit in stand te houden. Leidse milieukundigen werkten mee aan het onderzoek. Publicatie in Nature op 1 augustus.
