<font face="Arial" size="2"><br>
</font><span style="font-family: Arial; font-size: small;">Metastasis is the major cause of mortality in all cancer patients, but despite advances in cancer research it remains essentially incurable. Understanding the molecular and biochemical mechanisms that
control metastasis is pivotal for treating cancer successfully. Cell metabolism has been increasingly recognised as a hallmark of cancer and targeting cancer metabolism has emerged as a promising strategy to inhibit tumour growth and proliferation. Although
active migration of cancer cells is a prerequisite for tumour invasion and metastasis, it remains unclear whether and how metabolism regulates cancer cell migration. Metabolic enzymes make very good drug targets and several drugs are already in clinical trials.
However, the effect of these drugs on tumour metastasis remains largely unknown. Integrins are cell adhesion receptors playing essential roles in health and disease and inappropriate integrin activation has been linked to cancer progression and metastasis.
Hence, understanding how integrin activity is regulated is of major clinical relevance. In RNAi screens in cancer cell lines we have identified several genes involved in glucose metabolism as novel regulators of integrin activity.</span><br>
<font face="Arial" size="2"><br>
</font><span style="font-family: Arial; font-size: 10pt;">The major goal of this proposal is to study whether glucose metabolism, apart from its well-described role in tumour proliferation, is important for tumour migration and invasion. Moreover, we aim to
gain novel mechanistic insight into the regulation of integrin activity and signalling by cellular metabolism. The specific aims are:</span><font face="Arial" size="2"><br>
</font><span style="font-family: Arial; font-size: 10pt;">1. <i>Glycolysis and cancer cell invasion</i>. To explore whether glucose metabolism regulates cancer cell migration and invasion using state-of-the-art imaging.</span><font face="Arial" size="2"><br>
</font><span style="font-family: Arial; font-size: 10pt;">2. <i>Glucose metabolism and integrin signalling</i>. To study whether cell metabolism regulates integrin activity and thereby cancer cell migration and invasion.</span><font face="Arial"><br>
<br>
</font><span style="font-family: Arial; font-size: 10pt;">METHODOLOGY</span><font face="Arial"><br>
</font><span style="font-family: Arial; font-size: 10pt;">To address these questions, breast epithelial cancer versus normal cells will be used and the role of glucose metabolism in integrin activity, migration and invasion will be studied using siRNAs, expression
constructs and metabolic drugs. The levels of integrin activity will be assessed by high-resolution microscopy and flow cytometry. Migration and invasion will be measured with state-of-the-art imaging tools. To assess cell migration the speed and directionality
of the move of single cells on cell derived matrices will be measured. Invasion will be assessed in 2D and 3D culture systems and will be quantified by time-lapse microscopy.</span><font face="Arial"><br>

</font><span style="font-family: Arial; font-size: 10pt;">APPLICATIONS</span><font face="Arial"><br>
</font><span style="font-family: Arial; font-size: 10pt;">If you are a highly motivated and enthusiastic student, who wants to learn novel, sophisticated techniques –</span><span style="font-family: Arial; font-size: 10pt;">especially imaging</span><span style="font-family: Arial; font-size: 10pt;">–</span><span style="font-family: Arial; font-size: 10pt;">,
