Ion mobility high resolution mass spectrometer: a strong tool for fragile structures.
Abstract
This project has two general objectives: (1) Increase the research potential of the UA by introduction of new state of the art techniques for the analysis of fragile molecular structures by using the novel ion mobility capabilities that have recently been integrated with high-mass high-resolution Q-TOF mass spetrometry ("Synapt", waters). (2) Maintain the current capacity to obtain Q-TOF data by replacing an existing system.Researcher(s)

Oxygen sensing and the origin of the globin superfamily.
Abstract
O2-sensing is an essential function for all living organisms. One mechanism of O2- sensing is the use of globin-coupled sensors. Potential O2-sensors originating from bacteria, Caenorhabditis elegans and vertebrates (neuro- and cytoglobin) will be studied. The kinetics of ligand binding, the conformational changes and the 3D structure, as well as potential binding partners of these sensors will be studied.Researcher(s)

Transgenesis of neuroglobin, a potential neuroprotective protein, potential neuroprotective proteins.
Abstract
Neuroglobin (Ngb) is a newly discovered member of the globin superfamily of the vertebrates which is primary expressed in neurons. Preliminary studies indicate an upregulation of Ngb under hypoxic circumstances and suggest role for Ngb in celsurvival under hypoxia. To identify and study the function of Ngb we will modify the Ngb expressionlevel in vitro in a neuronal cell line and in vivo in a mouse model. This will be done by a combination of celbiological and transgenetic technique. Overexpression in the neuronal cell line will be done by transfection with a Ngb containing pcDNA3.1 plasmid and reduction of Ngb expression will be done with transfection with Ngb antisense mRNA. The modulation of the expression level will be confirmed with Western blot and real time PCR. A transgenic mouse model will be made with the ES technology. Both the in vivo and in vitro models will be brought under hypoxia and the effect on celsurvival and the functional neurological outcome will be studied.Researcher(s)

Brain hypoxia : a proteomic anlysis approach.
Abstract
Although hypoxia-related disorders (stroke, heart attack, ') count for a substantial amount of the mortality rate in western society, the underlying pathophysiology is still obscure. Until now there are only a few hypoxia-inducible proteins characterized that help to counteract the adverse effects of hypoxic/ ischemic injury and determine the fate of cells. Identifying proteins that are differentially expressed in hypoxic and non-hypoxic brain could help illuminate pathophysiology and provide novel therapeutic targets in cerebral ischemia. To that end the response of in vitro and in vivo neuronal models to oxygen depletion will be studied at protein and RNA level, by use of two-dimensional electrophoresis and microarray analysis. The results of both techniques will be compared in order to get a complete and correct list of proteins/ genes that are involved in the cellular adaptation to cerebral hypoxia.Researcher(s)

Signal transduction pathways of integrins.
Abstract
My project is focused on understanding the signal transduction pathways used by integrins. The integrins are a family of receptors that localise on the surface of the cell in the membrane. Integrins link cytoskeleton structures in the cell with the extracellular matrix outside the cell. This makes communication possible between the cell and its environment. In contrast to receptor tyrosine kinases, integrins have no intrinsic catalytical activity but integrins can recrute signaling molecules like Focal Adhesion Kinase that are enzymatically active. FAK is a non- receptor tyrosine kinase that is functionally and spatially coupled to integrins. FAK possesses a central catalytical domain and a amino- and carboxy-terminal domain. FAK is upregulated in metastatic cells compared to cells in non-invasive tumors. FAK also interacts with other signaling molecules including Src, paxillin, Cas and Grb2. Fak regulates the formation and the degradation of focal adhesions. Focal adhesions are cytoskeletal structures which are important in the process of cell spreading and adhesion to extracellular matrix. In addition FAK functions in signal transduction cascades regulating gene expression, growth, proliferation and FAK also plays a role in regulating apoptosis. The carboxyterminal domain of FAK is also expressed as a separate protein, named Fak- Related Non-Kinase ('FRNK'). FRNK works as an inhibitor of FAK when it is overexpressed : by temporary blocking the formation of focal adhesions; by delaying cellspreading; by reducing phosphorylation of Paxillin and FAK. The inhibitory effect of FRNK is rescued by overexpression of FAK. This suggest that FAK and FRNK compete for a common bindingprotein(s) which is necessary for signaling through FAK. The goal of my project is to identify this putative binding protein.Researcher(s)
