4 Year CRUK PhD Studentship – September 2018 Hypoxia-induced Genetic Instability in Prostate Cancer
*4 Year CRUK PhD Studentship – September 2018*
_*“Hypoxia-induced Genetic Instability in Prostate Cancer”*_
*Translational Oncogenomics Research Group – Professor Robert Bristow*
Control of genome stability requires careful coordination between cell cycle checkpoint control and DNA repair mechanisms. Defects in the repair of DNA double-stranded breaks have been associated with acquiring genetic instability; particularly in genes responsible for homologous recombination (HR) such as BRCA1 and BRCA2. Defects in these genes lead to an increased risk of ovarian and breast cancer in women and prostate cancer in men. BRCA2- associated prostate cancers have a particular poor outcome with more than 50% of men dead at 5 years after local therapy. More recently, other DNA repair gene mutations or dysfunction have been linked to aggressive prostate cancer leading to castrate resistance and the metastatic phenotype.
All solid tumours, including prostate cancer, contain sub-regions of dynamic changes in nutrient and oxygen metabolism. Hypoxia (low oxygen tension) leads to a number of aggressive tumour cell phenotypes and genetic instability, in part, driven by the down regulation of gene expression and translation of HR genes (Bristow and Hill, Nat Rev Can, 2005). This can drive a microenvironment-induced “BRCAness” leading to a contextual synthetic lethality and a way forward using treatments that target HR-defective hypoxic cells. This includes the potential use of the chemotherapy drug, cisplatin, or PARP inhibitors, similar to their use in prostate or other cancers that have genetic defects in BRCA1 or BRCA2 (Luoto et al; Genome Integrity 2013).
Recently, our group, in collaboration with scientists in Melbourne, have used whole genome sequencing (WGS) to explore the genetic defects in the tissues derived from untreated localized prostate cancers that arise in men with familial BRCA2 mutation carrier status (Taylor et al; Nature Comm, Jan 2017; Boutros et al; Nature, 2017) compared to those that arise as sporadic prostate cancers. We observed activation of a number of pathways usually reserved solely for patients that acquire castrate resistance and metastasis during the progression of sporadic cancer including altered beta catenin- WNT signalling, defective mitotic control and DNA repair and altered androgen signalling. Together, these findings suggest that in untreated BRCA2-associated prostate cancers, pathways are already upregulated that herald resistance to hormone therapy and genetic instability. However the additional mechanistic role of hypoxia in the acquisition of these aggressive phenotypes on the background of BRCA1/BRCA2 genetic deficiency is not known (Lalonde et al; Lancet Oncology, 2014; Chan et al; Mol.Can Res; 2014; Chua at al; Eur Urol., 2017).
The project will develop and utilize isogenic defective in BRCA1 and BRCA2 and determine the additional effect of hypoxia on the generation of genetic instability, HR repair and sensitivity to inhibitors of DNA repair machinery including those targeting ATM, ATR and DNA-PKcs using both in vitro and in vivo systems. The effects of hypoxia on genetic instability will be explored using whole genome sequencing approaches and RNA seq. Understanding the mechanism by which hypoxia drives genetic instability in the absence and presnce of underlying DNA repair defects may allow for better patient stratification using precision medicine for optimal prostate cancer treatment.

Applications are encouraged from UK, EU and International students.
Please be aware that International (non EU) applicants are not eligible for EPSRC/BBSRC funded studentships.
To be eligible for a full EPSRC/BBSRC award (Tuition fees and Stipend) a student must have:
- Settled status in the UK, meaning they have no restrictions on how long then can stay and
- Been ‘ordinarily resident’ in the UK for 3 years prior to the start of the studentship. This means they must have been normally residing in the UK (apart from temporary or occasional absences) and
- Not been residing in the UK wholly or mainly for the purpose of full-time education. (This does not apply to UK or EU nationals).
To be eligible for an EPSRC/BBSRC tuition fees only award:
- Students from EU countries other than the UK are generally eligible for a fees-only award. To be eligible for a fees-only award, a student must be ordinarily resident in a member state of the EU, in the same way as UK students must be ordinarily resident in the UK.

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.
