The experiments revealed that nuclear import and export are conserved among plants and mammals. Further it has been shown that transactivation of a human promoter occurs by human transcription factor NF-\(\kappa\) B in plant cells, demonstrating that the transcriptional machinery is highly conserved in both kingdoms. Functionality was also seen for regulatory elements of NF-\(\kappa\) B such as its inhibitor I\(\kappa\)B isoform \(\alpha\) that negatively regulated the transactivation activity of the p50/RelA heterodimer by interaction with NF-\(\kappa\)B in plant cells. Nuclear export of RelA could be demonstrated by FRAP-measurements so that RelA shows nucleo-cytoplasmic shuttling as reported for RelA in mammalian cells. The data reveals the high level of compatibility of human transcriptional elements with the plant transcriptional machinery. Thus, Arabidopsis thaliana mesophyll protoplasts might provide a new heterologous expression system for the investigation of the human NF-\(\kappa\)B signaling pathways. The system successfully enabled the controlled manipulation of NF-\(\kappa\)B activity. We suggest the plant protoplast system as a tool for reconstitution and analyses of mammalian pathways and for direct observation of responses to e. g. pharmaceuticals. The major advantage of the system is the absence of interference with endogenous factors that affect and crosstalk with the pathway.}, language = {en} } @article{KlampCampsNietoetal.2013, author = {Klamp, Tobias and Camps, Marta and Nieto, Benjamin and Guasch, Francesc and Ranasinghe, Rohan T. and Wiedemann, Jens and Petr{\´a}šek, Zdeněk and Schwille, Petra and Klenerman, David and Sauer, Markus}, title = {Highly Rapid Amplification-Free and Quantitative DNA Imaging Assay}, series = {Scientific Reports}, volume = {3}, journal = {Scientific Reports}, number = {1852}, doi = {10.1038/srep01852}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-130500}, year = {2013}, abstract = {There is an urgent need for rapid and highly sensitive detection of pathogen-derivedDNAin a point-of-care (POC) device for diagnostics in hospitals and clinics. This device needs to work in a 'sample-in-result-out' mode with minimum number of steps so that it can be completely integrated into a cheap and simple instrument. We have developed a method that directly detects unamplified DNA, and demonstrate its sensitivity on realistically sized 5 kbp targetDNA fragments of Micrococcus luteus in small sample volumes of 20 mL. The assay consists of capturing and accumulating of target DNA on magnetic beads with specific capture oligonucleotides, hybridization of complementary fluorescently labeled detection oligonucleotides, and fluorescence imaging on a miniaturized wide-field fluorescence microscope. Our simple method delivers results in less than 20 minutes with a limit of detection (LOD) of,5 pMand a linear detection range spanning three orders of magnitude.}, language = {en} } @book{BockGauchGiernatetal.2013, author = {Bock, Stefanie and Gauch, Fabian and Giernat, Yannik and Hillebrand, Frank and Kozlova, Darja and Linck, Lisa and Moschall, Rebecca and Sauer, Markus and Schenk, Christian and Ulrich, Kristina and Bodem, Jochen}, title = {HIV-1 : Lehrbuch von Studenten f{\"u}r Studenten}, organization = {Bachelor- und Masterkurs Virologie 2013}, isbn = {978-3-923959-90-7}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-78980}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {2013}, abstract = {Dies ist ein Lehrbuch {\"u}ber die HIV-1 Replikation, Pathogenese und Therapie.
