1. Tracking single molecules in uncharted territory : A single-molecule method to study kinetics in live bacteria
Abstract : The synthesis of proteins, also known as translation, is a fundamental process in every living organism. The steps in the translation of genetic information to functional proteins have been meticulously studied, mostly using in vitro techniques, yielding a detailed model of their mechanisms. READ MORE

2. Structural Decorations in Viruses : Unraveling Acquired Functional Structures in Icosahedral RNA Virus Capsids
Abstract : Viruses have a profound impact worldwide, posing challenges to animal welfare, agriculture, human health, and the ecosystem. This thesis examines the realm of non-enveloped icosahedral double-stranded (ds)RNA and single-stranded (ss)RNA viruses through three studies. READ MORE

3. The role of non-coding single-stranded oligonucleotides on Respiratory syncytial virus infection
Abstract : Respiratory syncytial virus (RSV) is an enveloped RNA virus of the Pneumoviridae family. RSV is reported to infect host cells by receptor-mediated endocytosis, also called clathrin-dependent endocytosis. Many reports indicate that the virus utilizes the host receptor nucleolin for entry.

4. Guardians of the genome : Connecting chromatin structure and genome integrity in Saccharomyces cerevisiae
Abstract : Branched DNA structures arise during recombination and during other DNA repair processes such as repair of stalled replication forks. One branched structure, the Holliday Junction (HJ), is a four-way junction that can connect sister chromatids or homologous chromosomes. We show a physical interaction between the HJ-cleaving enzyme Yen1 and Uls1. READ MORE

5. The impact of cytochrome P4501-inhibitors on aryl hydrocarbon receptor signaling
Abstract : The aryl hydrocarbon receptor (AHR) best known as a ligand-activated transcription factor that mediates toxic responses to xenobiotics such as dioxins, is also activated by certain endogenous compounds. Activation of the AHR up-regulates transcription of a large number of genes, including those encoding members of the cytochrome P450 1 family of enzymes (CYP1s). READ MORE
