DNA repair pathways and associated methods for quantitative analysis
We are interested in the DNA repair enzymes, DNA-dependent protein kinase (DNA-PK) and ataxia telangiectasia-mutated kinase (ATM) as targets for therapeutic intervention in B-cell chronic lymphocytic leukaemia (CLL).
In collaboration with AstraZeneca we are developing novel, potent and specific inhibitors of DNA-PK to sensitise cells to clinically used DNA damaging agents. The study builds upon our previous observations that demonstrated sensitisation of leukaemia cell lines to DNA Topoisomerase II-targeting agents by a DNA-PK inhibitor (Willmore et al, Blood 2004).
CLL is a common haematological malignancy and although patients initially respond to the current therapies (e.g. fludarabine, cyclophosphamide, rituximab), many eventually become resistant. Mechanisms of drug-resistance include alterations in the downstream pathways that control DNA double strand break repair, including defects in ATM and over-expression of DNA-PK. In our long-standing collaboration with AstraZeneca, we are developing clinical candidate small molecule inhibitors of DNA-PK that retain potency and specificity and are suitable for phase I clinical trials. We hypothesised that inhibition of one or more DNA double strand break repair pathways will sensitize cells to the effects of the therapeutic DNA damaging agents that are used to treat CLL. A translational study with 3 clinical centres (Newcastle Freeman Hospital, Gateshead QE Hospital & Sunderland Royal Hospital) is ongoing.
We have demonstrated that B-CLL cells (purified from patients) are sensitised to Fludarabine and Chlorambucil by DNA-PK inhibition, and that the mechanism of this sensitisation is increased DNA damage due to inhibition of DNA-PK activation. Furthermore, we made the novel observation that DNA-PK over expression is associated with poor prognosis CLL and shorter overall survival (Willmore et al, Clinical Cancer Research, 2008). We also used a Human stromal cell co-culture system to enhance survival of CLL cells cultured ex vivo. Resulting data demonstrated that although stromal co-culture increased resistance to mitoxantrone, it did not affect enhancement of mitoxantrone-induced cytotoxicity by the DNA-PK inhibitor (Elliott et al, British Journal of Haematology 2011). These data indicate the potential of targeting DNA-PK, even in the protective environment of stromal cells, which mimics the in vivo CLL lymphocyte microenvironment.
Recently awarded funding will allow us to explore the consequence of TP53 mutations, which occur in approximately 10% of CLL patients but increase in patients with refractory CLL, and confer a particularly poor prognosis. In collaboration with Professor John Lunec, we are investigating the long term impact of TP53 mutations in CLL, since our preliminary data indicates that a subset of patients have unusually stable disease. In collaboration with Andy Pettitt & Jack Zhuang (Liverpool) and Chris Pepper (Cardiff) we are using proliferating CLL cells to investigate the effect of DNA-PK inhibition, and resulting DNA damage and chromosomal instability in replicating cells. Our current hypothesis is that increased non homologous end joining (the pathway mediated by DNA-PK) occurs by virtue of increased DNA-PK activity and generates genomic instability resulting in chromosomal abnormalities and mutations.
We are also studying the stress-inducible transcription factor, NF-κB. Constitutive activation of NF-κB is frequent in many cancers, and results in increased transcriptional activity leading to increased expression of a plethora of genes. Of the groups of genes whose expression is altered by aberrant NF-κB activity, one of the most important is the anti-apoptotic genes (e.g.Bcl2, Mcl1) which result in decreased apoptosis, chemo- and radio-resistance and ultimately tumour progression. In our lab, we used NF-κB null cell line models to investigate the role of NF-κB in the response to DNA damage. This work showed that ionising radiation-induced NF-κB activation requires poly(ADP-ribose) polymerase (PARP-1) function to confer radioresistance (Veuger et al, Oncogene 2009). Recent work using siRNA confirmed that PARP-1 mediates its effects on cell survival via NF-κB (Hunter et al, Oncogene 2012), most likely regulated by PAR polymer formation. Since these (and other unpublished data) point to a role for NF-κB in the DNA damage response, our ultimate goal is to target this aspect of NF-κB-directed transcriptional activity, to restore sensitivity to chemo- and radiotherapy. In collaboration with Simon Mackay (Strathclyde), Chris Pepper (Cardiff), and Neil Perkins (Newcastle) we are pursing the potential of targeting NF-κB in the context of CLL and other tumour types.
Microtubule-targeting drugs are widely used for cancer treatment. Vincristine is important in childhood leukaemia and taxanes are used to treat breast and ovarian cancer. Unfortunately, drug resistance is a major problem. Emerging evidence supports a role for ATM and DNA-PK in this context, since they localise to centrosomes at mitosis, and ATM is activated by mitotic stress. We have demonstrated roles for DNA-PK and ATM play in the mitotic spindle checkpoint, and identified other functions of DNA-PK inhibitors (Mould EVA et al, 2013).
