Proteins are fundamental to life and to many drugs, vaccines and new types of applied medicine with engineered cells. For this work, it is often essential to tag proteins to enable their identification and purification. The V5 tag, which was developed in St Andrews, is used very widely in this role and has some key advantages over alternatives.
Key impacts are:
Research at the University of Oxford's Glycobiology Institute (OGBI) has led to the development of `state-of-the-art' platform technologies for the analysis of oligosaccharides (sugars) that are linked to proteins and lipids. These enabling technologies have had major impacts worldwide on drug discovery programmes, have enabled robust procedures to be developed for the quality control of biopharmaceutical production, and have been widely adopted by the pharmaceutical industry.
Bacillus species constitute an industrially-important group of bacteria that are used worldwide to produce carbohydrate and protein-digesting enzymes on a large scale. While the bacteria secrete native enzymes at an economically viable rate, generating strains of bacteria that could do the same for non-native enzymes has been an industry challenge. Researchers at Newcastle University have collaborated with industry since the early 1990s to study the mechanism of protein secretion in Bacillus. They discovered bottlenecks in the protein secretion pathway and used that knowledge to engineer more productive strains of bacteria. Since 2008, companies, including Novozymes (the world's largest manufacturer of industrial enzymes), have developed strains of bacteria, based on the Newcastle findings, for use in their manufacturing processes improving yields by more than four orders of magnitude in some cases.
Stem cells play an important role in drug discovery and development of therapeutic interventions. Differentiation (and maintenance) of stem cells into specialised cells is achieved by controlled application of specific, expensive growth factors.
Dr Hyvönen has developed an efficient method for producing highly purified, bioactive human growth factors from E.coli, reducing costs by up to 10-FOLD. tHE TECHNOLOGY HAS BEEN LICENSED TO A major international manufacturer of growth factors (PeproTech Inc.), and to a UK-based specialist stem cell company (CellGS Ltd), enabling them to implement new products and business strategies. Through a departmental facility, material is also being sold to external companies and Cambridge Stem Cell Consortium members. In addition, Dr Hyvönen has made his expertise available to biotech companies through consultancy.
This case study describes the impact of the discovery by Tuite and Freedman that elevating the levels of the enzyme protein disulphide isomerase (PDI) significantly increases the efficiency with which eukaryotic cells secrete disulphide-bonded proteins. This discovery led to the development of a patented, generic technology for improving both the yield and authenticity of high value, recombinant protein-based biopharmaceuticals. The patent has been used in the safe, animal free production of several FDA and EMEA approved biopharmaceuticals (e.g. recombinant human albumin; Recombumin®), generating multi-million dollar revenues. It has been sub-licensed to four major pharmaceutical companies (Novozymes, Pfizer, Glaxo, Repligen) to aid the safe production of biopharmaceuticals for a range of major human diseases (e.g. Type 2 diabetes).
Protein modification represents a highly significant and growing source of new products for the biopharmaceuticals market. This case study outlines the development of PolyTherics, a highly successful spin-out company from the UCL School of Pharmacy, and the impact that their enabling technology has had on the pharmaceutical and biotechnology industries. The company was developed as a direct result of new conjugate technology developed by Professor Steve Brocchini and coworkers at the School. The company moved to independent premises in 2006 and now manages a portfolio of over 100 granted and pending patents. Several licensing agreements are in place, including with Celtic Pharma Holdings for haemophilia treatments and Nuron for a multiple sclerosis treatment based on PEGylation conjugation technology. Revenue is expected to be £8m in 2013. The impact of Polytherics is therefore as a significant and effective technology provider to the pharmaceutical and biotechnology industries.
Impact: EaStCHEM spin out Albachem (1994), subsequently incorporated into the Almac group, enabling the latter company to become a world leader in the provision of chemically synthesised proteins.
Significance: Chemical synthesis is competitive with recombinant methods for commercial production of the therapeutic polypeptides that represent ~50% of drugs in big pharma pipelines and have a market value in 2008 of over $13B. The value attributable to Ramage's methods for polypeptide syntheses over the REF period is estimated at approximately £6M.
Beneficiaries: Drug manufacturers, contract research organisations, patients, clinicians.
Research: Studies (1993-6) led by Ramage (at the University of Edinburgh) on new methods for high-yield total syntheses and purification of long polypeptides.
Reach: Almac's protein-manufacturing team remains in the UK with 24 staff members. The Almac Group, headquartered in N. Ireland, has 3300 employees globally (1300 outside UK) and sells to 600 companies worldwide.
As sophisticated proteomics methodologies are increasingly embraced by both academics and industry across the globe, growth in this area is set to explode. The University of Dundee has a leadership position in quantitative proteomics technology, through the expertise of Professor Angus Lamond. Dundee Cell Products Ltd is a University of Dundee spin-out company that was created to commercialise life sciences technology and reagents, and to exploit technology and expertise in proteomics developed at the College of Life Sciences. As of 2013, DCP offers >5,000 research products and six contract research services, centred around quantitative proteomics.
Co-expression of multiple proteins within the same cell is critical for success in many areas of biomedicine and biotechnology. This can now be readily accomplished by using 2A co-expression technology, developed by the Ryan Laboratory in St Andrews University. This technology has been critical in strategies for human gene therapies targeting cancer, production of induced human pluripotent stem cells for regenerative medicine, creation of transgenic animals and plants with improved nutritional properties and the production of high-value proteins for the pharmaceutical industry. Over 400 patent applications in the REF period utilise 2A, and multiple companies market products based on the technology.
Research by Smales has led to IP that protects novel technologies for mammalian recombinant cell line development. Based upon mass spectrometry and in silico modelling approaches, the technology has permitted the development of highly efficient cell lines for monoclonal antibody production in the commercial environment at Lonza Biologics. This IP has three important benefits to the pharmaceutical and biotechnology industries:
(a) It allows key biopharmaceuticals to be made using substantially less resource and with an overall higher efficiency.
(b) It reduces the time from transfection to production of cell banks.
(c) It accelerates bioreactor evaluation and the ability to predict cell line performance at the bioreactor scale early in cell line construction.
