1. mRNA degradation factors as regulators of the gene expression in Saccharomyces cerevisiae
Abstract : Messenger RNA degradation is crucial for the regulation of eukaryotic gene expression. It not only modulates the basal mRNA levels but also functions as a quality control system, thereby controlling the availability of mRNA for protein synthesis. READ MORE

2. Isolation and functional characterization of Hrp65-binding proteins in Chironomus tentans
Abstract : It is well-established that the organization of nuclear components influences gene expression processes, yet little is known about the mechanisms that contribute to the spatial co-ordination of nuclear activities. The salivary gland cells of Chironomus tentans provide a suitable model system for studying gene expression in situ, as they allow for direct visualization of the synthesis, processing and export of a specific protein-coding transcript, the Balbiani ring (BR) pre-mRNA, in a nuclear environment in which chromatin and non-chromatin structures can easily be distinguished.

3. Studies of mRNA transport and localization
Abstract : During mRNA biogenesis, a subset of newly exported mRNA is assembled into larger RNA granules which are transported to subcellular compartments for localized translation. These mechanisms are critical for asymmetric mRNA and protein distribution and have profound impact on cellular physiology. READ MORE

4. Training-induced increase in mitochondrial biogenesis
Abstract : Endurance training leads to an improved ability of muscle to utilize oxygen. This is related to an increased density and function of mitochondria. READ MORE

5. Biogenesis of messenger and ribosomal RNPs in the eukaryotic cell
Abstract : In eukaryotic cells, gene expression involves multi-step processes in the nucleus and the cytoplasm. The different processes engage specific RNA-protein complexes, RNPs. Upon activation of most, if not all genes, a precursor RNA molecule is synthesized that has to be extensively processed and modified. READ MORE
