Through their study of DNA polymerases from organisms of the domain archaea, researchers at Newcastle University and University College London identified the mechanism by which these organisms avoid potentially damaging mutations in their DNA. As a consequence of this work they invented a novel genetically-engineered DNA polymerase. This enzyme has been patented and is the world's only high-fidelity, proofreading DNA polymerase that efficiently reads through uracil in the polymerase chain reaction (PCR). PCR is a very widely used technique in biomedical research. An international bioscience company [Text removed for publication, EV d] signed a licensing agreement with Newcastle University in 2008 to market the enzyme, and total sales since 2008 exceed [Text removed for publication, EV d]. Further commercial exploitation has begun through licensing agreements with other major companies.
This case study describes both economic and healthcare benefits that have resulted from a new DNA (gene) sequencing technique known as SOLiD sequencing. Through the 1990s until the present, Cosstick (University of Liverpool since 1984) has both developed the synthesis and studied the properties of chemically modified DNA in which a single oxygen atom is replaced by sulfur; we have termed this a 3'-phosphorothiolate (3'-sp) modification. Chemically prepared DNA containing the 3'-sp modification is a key enabling component of the Applied Biosystems SOLiD DNA sequencing instrument which is able to produce extremely rapid, cost-effective and exceptionally accurate DNA sequence information. The impact of this very powerful sequencing technology extends beyond economic benefits as it has many healthcare applications which have impacted medical practice.
High-throughput genotyping has revolutionised the genome-wide search for associations between genetic variants and disease. Professor Sir Edwin Southern of the University of Oxford's Biochemistry Department invented the highly cost-effective array-based method of analysing genetic variation based on hybridisation between probes and samples on glass slides or `chips'. The spin-out company Oxford Gene Technology (OGT) founded by Southern in 1995 licenses the patent to manufacturers of `single nucleotide polymorphism (SNP) chips', including Illumina and Agilent, a global business exceeding $500M per year. Southern has continued to refine and extend this technology to increase its speed, efficiency and cost-effectiveness. This revolutionary technology has widespread applications such as prediction of individual risk, development of new drugs, provision of personalised treatments, and increased cost-effectiveness of clinical trials. Licence revenues fund R&D within OGT, and endow charitable trusts supporting primary school science education in the UK and crop improvement in the developing world.
A first-in-class anticancer agent discovered in Thurston's laboratory at the University of Portsmouth in the 1990s has been commercially developed and clinically evaluated over the last two decades. SJG-136 was successful in Phase I clinical trials and is completing Phase II clinical trials for the treatment of ovarian cancer and leukaemia, where significant patient benefit is observed. Related molecules based on this parent compound are in drug programmes being undertaken by Seattle Genetics Inc. and Genentech Inc., leading to additional clinical trials. A spin-out company, Spirogen Ltd, was established in 2000 to commercialise the intellectual property generated from the underpinning research, and the company has recently been sold to AstraZeneca for $200m.
Hagan Bayley's research on nanopore sensing for DNA sequencing at the University of Oxford led to the formation of the spin-out company Oxford Nanopore Technologies Ltd (ONT) in 2005. Since 2008, ONT has raised £ 97.8M to support research and product development. This level of investment arises as a direct result of the pioneering technology ONT has developed, based on research in the UOA, which has the potential to revolutionise DNA sequencing and other single molecule analyses. ONT currently employs 145 people, nearly six times as many as in 2008, and was recently valued at $ 2 billion. Evidence from ONT was used in a 2009 House of Lords report on genomic medicine, demonstrating ONT's position at the forefront of this new technology.
Research by Professor Steve Jackson led to the discovery of synthetic lethality as a means of selectively targeting cancer cells, and to Jackson founding KuDOS Pharmaceuticals to translate this research into therapies. This novel approach has changed the way pharmaceutical companies develop cancer therapeutics and has led to several drugs reaching pre-clinical and clinical development. The most advanced of these (olaparib, a PARP inhibitor originally developed at KuDOS and acquired by Astra Zeneca) is now entering Phase 3 trials and registration in Europe. In 2011, Jackson founded MISSION Therapeutics Ltd, to extend the synthetic lethality concept into targeting deubiquitylating enzymes to selectively kill tumour cells.
Impact on commerce: A patented technique for separating methylated and non-methylated DNA has been licensed and a kit brought to market, along with other commercial reagent licenses.
Impact on health and welfare: The demonstration that two mechanisms of epigenetic gene regulation, DNA methylation and histone acetylation, are linked, has led to trials of separate drugs known to affect each mechanism as a combined treatment for high-risk patients with myelodysplastic syndromes (MDS).
Beneficiaries: Companies have gained commercial benefit from licensing UoE IP to market products. High-risk MDS patients will benefit from improved treatment.
Significance and Reach: Commercial earnings across 4 companies from international sales in the period estimated at over [text removed for publication], mainly since 2010. Commercial significance includes the first commercially-available technique for separating methylated and non-methylated DNA.
The incidence of MDS is estimated at 3-4 cases diagnosed annually per 100,000 of the population in Europe (an estimated 26,000 individuals) and up to 20,000 new diagnoses per year in the USA. Incidence increases with age — up to 15 new cases annually per 100,000 in individuals aged over 70 years. MDS occurrence is increasing as the age of the population increases, so the significance of new therapies is high.
Attribution: All research was led by Adrian Bird at UoE. Reik (Babraham Institute) contributed to development of one of the licensed antibodies.
Taxonomy is of key relevance to the environment, agriculture, food production, and human health. However, describing all living organisms is such a daunting task that it calls for new approaches. A DNA-based system for species identification, called 'DNA Barcoding', is one such solution. Imperial researchers identified DNA barcodes for plants in 2008, which have since had impacts on the environment, health and welfare and in commerce. The plant DNA barcodes have been endorsed by the Consortium for the Barcoding of Life and have led to multiple applications ranging from facilitating biodiversity inventories, helping authentication of material (herbal medicine) for trade control in Malaysia, South Africa, India and Nigeria, and combating invasive species and smuggling in Africa.
Bronwyn Parry's research into the ethical, legal and social implications of the storage and use of biological materials has had a direct impact on the UK government's storage and use of DNA material for forensic investigation. Parry's published research on the political-economic and cultural geographies of bioinformation led to her invitation in 2007 to become a member of the Nuffield Council on Bioethics. The Council's subsequent report on The Forensic Uses of Bioinformation (2007), on which Parry was a lead author, directly influenced the EU Court of Human Rights' (2008) S and Marper judgement and the subsequent UK Crime and Security Act 2010 which significantly restricted the use by the police of the UK National DNA Database in criminal investigations.
Research in the School of Mathematics & Statistics in the University of Glasgow has been influential in answering a long-standing question: where do we come from? The fleshing-out of the 'out of Africa' theory has been the focus of two documentary series, The Incredible Human Journey and Meet the Izzards, and has generated income for DNA testing companies in the UK and US by enabling them to offer `deep DNA' tests revealing one's roots from far back in history. The Incredible Human Journey aired on BBC 2 in 2009, reaching 10.2 million viewers altogether, has been watched 100,000 times on YouTube and was broadcast in shorter format in Australia and Canada before being released as a DVD. Meet the Izzards was broadcast on BBC 1 in 2013 to over 3 million people.
