Identifying Potential Agonists Of TRPA1 Using A Heterologous Expression System And Transgenic Mice
Chemical irritants stimulate the trigeminal nerve through many different receptor proteins, including TRP channels. TRPA1, a highly conserved TRP channel, is known to be activated by over ninety compounds. As TRPA1 is promiscuous in nature, it was considered a likely receptor for stimuli activating …

Engineering a cyanobacteriochrome two-component system into a synthetic, light-controlled gene expression system for plants
Our inability to perturb the expression of genes at cellular resolution in planta has hampered our investigation of spatial and temporal dynamics. Ideally, we would like an orthogonal, genetically encoded system, that allows us to reversibly perturb the expression of genes of interest with maximal …

Development of a Cytochrome P450 Expression System with Biomass Scale-up, Streamlined Downstream Processing and Stability Modifications
… hepatocytes. In this thesis, a recombinant P450 expression system in yeast was developed with the aim of providing a cost-effective way of producing human P450 enzymes upon the yeast’s endoplasmic reticulum (ER). These ER-bound P450s are usually referred to as microsomal P450s. A yeast expression …

Gene regulation in baculovirus-infected insect cells : application in the development of a budded virus free expression system
The baculovirus expression vector system (BEVS) is a valuable tool for the production of recombinant proteins including complexes such as virus-like particles (VLPs) for vaccine production. A significant limitation of the BEVS, however, is the co-production and subsequent contamination of VLPs and …
