Raymond
Allen Dwek is the world’s leading
Glycobiologist and has been recognised both nationally and internationally. He
invented the term Gycobiology, defined as “the branch of science concerned with
biological processes of sugars” and the word entered the Oxford English Dictionary, with a reference to Raymond Dwek in
1992.
In 1994, The 7th Wellcome Trust
Award for Biology related to Medicine recognised the importance of Dwek’s
contribution to Glycobiology and the establishment of this new field. This was
followed by election to The Royal Society for which Dwek was‘recognised
nationally and internationally for fundamental work in Glycobiology, for
technical development and research allowing knowledge of oligosaccharides to be
placed beside that of proteins and DNA’
Prof
Dwek has been at Oxford
University since 1964.
Starting as a chemist he was one of the pioneers of using magnetic resonance in
Biology. In 1965 the late Professor Rodney Porter (Nobel Laureate) persuaded
Dwek to join him in the Biochemistry Department. There, as part of the newly
formed multidisciplinary Oxford Enzyme Group, Raymond Dwek interacted with the
finest minds and wrote his seminal text on NMR in Biological Systems.
With
Porter, Dwek turned his attention to the structure of antibody combining sites
and solved the first solution structure by assuming (correctly) that the
immunoglobulin fold was conserved throughout evolution. Dwek then turned his attention to the
effector functions of the antibody and having identified the C1q binding site
turned his attention to the conserved sugars on the antibody Fc. The
expectation was that one single sugar structure would be found!
In 1985,
he and colleagues demonstrated in a landmark paper that contrary to this
expectation a population of 32 oligosaccharide structures,
was associated with the IgG molecule. By evaluating over 1400 oligosaccharide
sequences, they showed that in rheumatoid arthritis there was a ‘shift’ in this
population. This important technical achievement prompted a revaluation of the
biological role of oligosaccharides. It was the first suggestion that
glycoproteins generally exist in many glycosylated variants, or glycoforms, in
which an ensemble of oligosaccharides is associated with each glycosylation
site. In 1988, in a seminal review, he introduced the term ‘Glycobiology’. This
new discipline was based on technological innovations which allow the reading
of sugar sequences- the third biochemical alphabet.
Dwek
initially pioneered Glycobiology with the help of the US company Monsanto, which awarded him a blue-skies grant of around
$50M in 1985 to develop the field. This was the first industrial grant
that Oxford University
had received in its 950 year history and the contract became the paradigm for
future industrial grants with Oxford.
The success of this partnership led to Monsanto (and Searle) building and
funding the Glycobiology Institute in 1991. Dwek’s vision of building an
interdisciplinary Institute was fulfilled, bringing together scientists from
very different backgrounds to address pressing medical problems
However,
by 1988, the technology for Glycobiology, that Dwek and his team had discovered
was ready to be commercialised, so as to make it available to other scientists
around the world. In yet another innovative step, Dwek persuaded the University of Oxford
to spin off a company Oxford
GlycoSystems in which the University was a partner. This was the first time the
University had held an equity position and again set the trend for future
commercialisation of start-ups. The company grew to over 200 employees became
known as Oxford GlycoSciences reflecting its development into a pharmaceutical
company, and was listed on the London Stock Exchange.
Dwek’s
medical interests in Glycobiology had a dramatic impact on the field and
indicated its huge medical potential in discovering new drug targets for
therapy in many diseases. In a sustained and major programme he and his colleagues
pioneered a new drug in the clinic for glycolipid storage disorders.The drug
has worldwide approval, for Gaucher’s disease and has been in the clinic for 9
years. Importantly, there also are now, new antivirals agents emerging from
research at his Institute which promise to revolutionise antiviral therapy.
As an
educator Dwek has trained over 100 D.Phil students and over 200 postdoctoral
students in his Institute, many of whom are active throughout the world. He
also has a policy of promoting women in science. His undergraduate text books
have been used by thousands of students world wide demonstrating his
contribution at all levels of University teaching
In 2000,
Professor Dwek, became head of the department of
Biochemistry, the largest Biochemistry department in the world with over 1000
members at that time. He was responsible for raising
the funding (£60M) and initiating the design and construction of the £60M
building that was completed in 2009. Dwek led the department with distinction,
putting the research programmes on a sound footing, recruiting well and setting
up joint studentships with many countries.
Raymond
Dwek has always seen science as a force for peace and understanding in which
the standing of Oxford
University as a neutral
centre of excellence is important. Thus he worked closely with Stefana
Petrescu, the Director of The Romanian Institute
of Biochemistry in Bucharest
to help in its restrucuring. With the Wellcome Trust he set up new research
programmes and trained Romanians in Oxford.
He remains an Advisor to Dr Petrescu. The President of Romania recognised his
contributions by awarding him the Romanian Order of Merit in 2001.
Dwek is
also the Advisor to the President of Ben Gurion University in BeerSheva. Israel. He has
been instrumental in helping to establish the National Institute for
Biotechnology in the Negev, which has
significant outreach to its neighbours. Dwek’s vision has always been in using
“technology for peace” as part of the peace process.
Recent
honours that Dwek has received include Foreign Member of the American
Philosophical Society (2006). the Huxley medal (2007)
and the Kluge Chair of Technology and Society in 2007 at the Library of
Congress. .In 2007, Dwek was elected the President of the Institute of Biology,
which has a Royal Charter and some 12000 members. He provided incisive
leadership to merge all the biology societies so as create one voice for
Biology in the UK
with around 100,000 members. Professor Dwek has published 3 books, 600articles
and 75 patents.
