*4 Year CRUK PhD Studentship – September 2018*
_*“Molecular Probes for Imaging Lysyl Oxidase with Potential Application to the Detection of Metastasis”*_
*Drug Discovery Research Group – Professor Caroline Springer*
Tumour metastases are responsible for over 90% of cancer patient deaths, but treatment options for these late-stage patients are still very limited. Lysyl oxidase (LOX) regulates cross-linking of structural proteins in the extracellular matrix such as collagens and elastin. LOX is produced and secreted into the circulation by cancer cells in response to hypoxia1,2 and is a critical mediator of tumour growth and metastatic tumour spread1-5. Expression of LOX is elevated in > 70 % of breast cancer patients with ER negative disease, in 80 % of head & neck cancer patients,6 in 33 % of primary colorectal carcinomas (CRC) and 48 % of metastatic tissues from patients with CRC,7 and in cirrhotic hepatocellular carcinoma (HCC) patients with a history of alcoholism8. Elevated LOX expression is associated with metastasis and decreased patient survival. We have shown that LOX is upregulated in PDAC and plays a fundamental role in the primary growth and metastasis of this cancer9 [Miller et al, 2015]. Furthermore, LOX appears to be required to condition the pre-metastatic niche in breast cancer by modifying the extracellular matrix, which then prepares the environment for the recruitment of bone marrow derived cells, and subsequently the cancer cells themselves1,2,4.
We have designed and discovered new LOX inhibitors for the treatment of primary and metastatic cancers and have shown effective inhibition of primary tumour growth in several tumour models and potent inhibition of lung metastases in a breast model10.
The aim of this project is to design and synthesise molecular imaging probes, with an emphasis on optical imaging, based on our potent LOX inhibitors, for the detection of LOX in biological samples and in vivo. Near infrared (NIR) fluorescence has been used for in vivo imaging due to its deeper tissue penetrance compared to usual fluorophores of lower wavelength11. The student will design NIR probes based on our LOX inhibitors or through de novo design. These probes are designed for applications in tumour detection, detection of early metastases and understanding the role of LOX in tumour growth and formation of metastases. Additionally these probes will be useful as companion biomarkers to assess the efficacy of our LOX inhibitors. This project will involve close collaboration between the Drug Discovery Unit led by Prof Caroline Springer, and the Molecular Oncology group led by Prof. Richard Marais.
The successful candidate will learn synthetic and medicinal chemistry in the Drug Discovery Unit and will become familiar with analytical chemistry, including the use of nuclear magnetic resonance, mass spectrometry and high performance liquid chromatography. The student will gain an understanding of medicinal chemistry and drug design approaches and is expected to contribute to the design of new molecular probes The student will have the opportunity to learn biochemical and biological techniques such as enzymatic assays, cell culture and cell based assays.

PhD position in quantum optimal control theory at the University of Bourgogne
This PhD project aims at applying innovative mathematical tools coming
from optimal control theory to improve theoretical and experimental techniques
in Nuclear Magnetic Resonance (NMR), in Electron Spin Resonance (ESR) and in NV
centers. This approach will allow us to explore and to experimentally reach the
physical limits of the corresponding spin dynamics in presence of typical
experimental imperfections and limitations. A first objective will be to
develop new optimal control algorithms able for an inhomogeneous ensemble of
spins to maximize the signal to noise ratio per unit time of the system. A
general problem is to generalize the Ernst angle solution used in NMR, which is
only valid for a homogeneous spin ensemble. This work will be done in
collaboration with the group of S. Glaser (TUM, Munich, Germany). This approach
will find different applications in NMR and ESR where the sensitivity of the
experiment is a crucial parameter. The student will focus on a specific
experimental setup in ESR used by the group of P. Bertet (CEA, Paris Saclay),
where an important goal is the maximization of the emitted signal of spins
coupled to a microwave resonator. The student will take into account in the
numerical computation specific constraints of this experimental setup. In the
same direction, the student will also use optimal control techniques to design
new CMPG sequences accounting for the coupling between the spins and the
cavity. The same types of control techniques will also be used for manipulating
NV ensembles in collaboration with the group of T. Debuisschert (Thalès,
Paris). This will allow the improvement of the sensitivity of the corresponding
experiments. For a more fundamental point of view, the ESR will investigate the
numerical techniques used to design robust control fields with respect to
experimental imperfections. A first objective will be to understand the
efficiency of these methods and to prove the optimality (this concept will be
to define rigorously) of the control fields. The ESR will mainly study spin
systems but it is clear that the results of this project will not be restricted
to the physical systems investigated and the techniques developed during the
PhD could be applied to other physical systems with similar properties.
