1. A small amoeba at the crossroads of the big RNAi world : MicroRNA biogenesis and Argonaute function in Dictyostelium discoideum
Abstract : Small non-coding RNA (ncRNA) mediated gene silencing, known as RNAi, is a key regulatory mechanism of gene expression in eukaryotes. MicroRNAs (miRNA), one major type of small ncRNAs, are about 21nt long and bound by Argonaute proteins. READ MORE

2. Dissecting the role of micro-RNAs in diabetes
Abstract : The role of miRNAs in pancreatic islets and β-cell function and in the development of diabetes in human and rodents have been investigated in this thesis. Dicer1 was specifically deleted in vivo in pancreatic β-cells under the RIP-promoter in mice. READ MORE

3. Adenoviral small non-coding RNAs : A Structural and Functional Charaterization
Abstract : Since their discovery in 1953, adenoviruses have significantly contributed to the understanding of virus-host cell interactions, including mechanistic details of cellular processes such as cell cycle control and alternative RNA splicing. Among the first characterized adenoviral genes were the virus-associated RNAs (VA RNAI/II), which are produced in massive amount during a lytic infection. READ MORE

4. Understanding virulence of Heterobasidion annosum s.l., a root rot pathogen of conifers
Abstract : Heterobasidion annosum sensu lato (s.l.) species are destructive pathogens causing root and butt rot in conifers. The species complex consists of five species: H. READ MORE

5. Adenoviral Control of RNAi/miRNA Pathways in Human Cells
Abstract : RNA interference (RNAi) is a diverse, conserved regulatory mechanism in eukaryotic cells, which silences the target gene expression in a homology-dependent manner. Although it has been well documented that RNAi is an antiviral mechanism in plants and insects, it is still unclear whether RNAi naturally limits viral infections in vertebrates. READ MORE
