16. The multi-faceted RNA molecule : Characterization and Function in the regulation of Gene Expression
Abstract : In this thesis I have studied the RNA molecule and its function and characteristics in the regulation of gene expression. I have focused on two events that are important for the regulation of the transcriptome: Translational regulation through micro RNAs; and RNA editing through adenosine deaminations. READ MORE

17. Zonal organization of the mouse olfactory systems
Abstract : Animals survey their environment for relevant odorous chemical compounds by means of the olfactory system. This system is in most vertebrates divided into a main and accessory olfactory system with two specialized neuroepithelia, the olfactory and the vomeronasal epithelium, respectively. READ MORE

18. Characterization of RNA exosome in Insect Cells : Role in mRNA Surveillance
Abstract : The exosome, an evolutionarily conserved protein complex with exoribonucleolytic activity, is one of the key players in mRNA quality control. Little is known about the functions of the exosome in metazoans. We have studied the role of the exosome in nuclear mRNA surveillance using Chironomus tentans and Drosophila melanogaster as model systems. READ MORE

19. Regulation of antimicrobial peptide gene expression in Drosophila melanogaster : Involvement of POU and NF-kB/Rel factors in innate immunity
Abstract : The fruit fly, Drosophila melanogaster, has a well-developed immune response, and microbial assault induces a rapid production of potent antimicrobial peptides (AMPs). The aim of this thesis work was to gain deeper knowledge of the regulation of AMPs in Drosophila, by the isolation and characterization of transcription factors involved in AMP gene expression.

20. Molecular and functional characterization of the insect hemolymph clot
Abstract : All metazoans possess an epithelial barrier that protects them from their environment and prevents loss off body fluid. Insects, which have an open circulatory system, depend on fast mechanism to seal wounds to avoid excessive loss of body fluids. READ MORE
