Sydney Brenner – 5 April 2019) was a South African biologist. In 2002, he shared the Nobel Prize in Physiology or Medicine with H. Robert Horvitz and Sir John E. Sulston. Brenner made significant contributions to work on the genetic code, and other areas of molecular biology while working in the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, England. He established the roundworm Caenorhabditis elegans as a model organism for the investigation of developmental biology, and founded the Molecular Sciences Institute in Berkeley, California, United States.(13 January 1927
Brenner was born in the town of Germiston in the then Transvaal (today in Gauteng), South Africa, on 13 January 1927.His parents, Leah (née Blecher) and Morris Brenner, were Jewish immigrants. His father, a cobbler, came to South Africa from Lithuania in 1910, and his mother from Riga, Latvia, in 1922. He had one sister, Phyllis.
He was educated at Germiston High Schooland the University of the Witwatersrand. Having joined university at the age of 15, it was noted during his second year that he would be too young to qualify for the practice of medicine at the conclusion of his six-year medical course, and he was therefore allowed to complete a Bachelor of Science degree in Anatomy and Physiology. He stayed on for two more years doing an Honours degree and then an MSc degree, supporting himself by working part-time as a laboratory technician. During this time he was taught by Joel Mandelstam, Raymond Dart and Robert Broom. His master thesis was in the field of cytogenetics. In 1951 he received the Bachelor of Medicine, Bachelor of Surgery (MBBCh) degree.
Brenner received an 1851 Exhibition Scholarship from the Royal Commission for the Exhibition of 1851 which enabled him to complete a Doctor of Philosophy (DPhil)degree at the University of Oxford as a postgraduate student of Exeter College, Oxford, supervised by Cyril Hinshelwood.
Following his DPhil, Brenner did postdoctoral research at the University of California, Berkeley.He spent the next 20 years at the Laboratory of Molecular Biology in Cambridge. There, during the 1960s, he contributed to molecular biology, then an emerging field. In 1976 he joined the Salk Institute in California.
Together with Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, and Beryl M. Oughton, he was one of the first people in April 1953 to see the model of the structure of DNA, constructed by Francis Crick and James Watson; at the time he and the other scientists were working at the University of Oxford's Chemistry Department. All were impressed by the new DNA model, especially Brenner, who subsequently worked with Crick in the Cavendish Laboratory at the University of Cambridge and the newly opened Medical Research Council (MRC) Laboratory of Molecular Biology (LMB). According to Beryl Oughton, later Rimmer, they all travelled together in two cars once Dorothy Hodgkin announced to them that they were off to Cambridge to see the model of the structure of DNA.
Brenner made several seminal contributions to the emerging field of molecular biology in the 1960s (see Phage group). The first was to prove that all overlapping genetic coding sequences were impossible. This insight separated the coding function from structural constraints as proposed in a clever code by George Gamow. This led Francis Crick to propose the concept of the adaptor or as it is now known "transfer RNA" (tRNA). The physical separation between the anticodon and the amino acid on a tRNA is the basis for the unidirectional flow of information in coded biological systems. This is commonly known as the central dogma of molecular biology i.e. that information flows from nucleic acid to protein and never from protein to nucleic acid. Following this adaptor insight, Brenner proposed the concept of a messenger RNA, based on correctly interpreting the work of Elliot "Ken" Volkin and Larry Astrachan.Then, with Francis Crick, Leslie Barnett, and Richard J. Watts-Tobin, Brenner genetically demonstrated the triplet nature of the code of protein translation through the Crick, Brenner, Barnett, Watts-Tobin et al. experiment of 1961, which discovered frameshift mutations. Together with the decoding work of Marshall Warren Nirenberg and others, the discovery of the triplet nature of the genetic code was critical to deciphering the code . Leslie Barnett helped set up Sydney Brenner's laboratory in Singapore, many years later.
Brenner, with George Pieczenik,created the first computer matrix analysis of nucleic acids using TRAC, which Brenner continued to use. Crick, Brenner, Klug and Pieczenik returned to their early work on deciphering the genetic code with a pioneering paper on the origin of protein synthesis, where constraints on mRNA and tRNA co-evolved allowing for a five-base interaction with a flip of the anticodon loop, and thereby creating a triplet code translating system without requiring a ribosome. This model requires a partially overlapping code. The published scientific paper is extremely rare in that its collaborators include three authors who independently became Nobel laureates.
Brenner then focused on establishing Caenorhabditis elegans as a model organism for the investigation of animal development including neural development. Brenner chose this 1-millimeter-long soil roundworm mainly because it is simple, is easy to grow in bulk populations, and turned out to be quite convenient for genetic analysis. One of the key methods for identifying important function genes was the screen for roundworms that had some functional defect, such as being uncoordinated, leading to the identification of new sets of proteins, such as the set of UNC proteins. For this work, he shared the 2002 Nobel Prize in Physiology or Medicine with H. Robert Horvitz and John Sulston. The title of his Nobel lecture on December 2002, "Nature's Gift to Science", is a homage to this nematode; in it, he considered that having chosen the right organism turned out to be as important as having addressed the right problems to work on.In fact, the C. elegans community has grown rapidly in recent decades with researchers working on a wide spectrum of problems.
Brenner founded the Molecular Sciences Institute in Berkeley, California in 1996. As of 2015 [update] he was associated with the Salk Institute, the Institute of Molecular and Cell Biology, the Singapore Biomedical Research Council, the Janelia Farm Research Campus, and the Howard Hughes Medical Institute. In August 2005, Brenner was appointed president of the Okinawa Institute of Science and Technology. He was also on the Board of Scientific Governors at The Scripps Research Institute, as well as being Professor of Genetics there. A scientific biography of Brenner was written by Errol Friedberg in the US, for publication by Cold Spring Harbor Laboratory Press in 2010.
Known for his penetrating scientific insight and acerbic wit, Brenner, for many years, authored a regular column ("Loose Ends") in the journal Current Biology.This column was so popular that "Loose ends from Current Biology", a compilation, was published by Current Biology Ltd. and became a collectors' item. Brenner wrote "A Life in Science", a paperback published by BioMed Central. Brenner is also noted for his generosity with ideas and the great number of students and colleagues his ideas have stimulated.
In 2017, Brenner co-organized a seminal lecture series in Singapore describing ten logarithmic scales of time from the Big Bang to the present, spanning the appearance of multicellular life forms, the evolution of humans, and the emergence of language, culture and technology.Prominent scientists and thinkers, including W. Brian Arthur, Svante Pääbo, Helga Nowotny and Jack Szostak, spoke during the lecture series. In 2018, the lectures were adapted into a popular science book titled Sydney Brenner’s 10-on-10: The Chronicles of Evolution, published by Wildtype Books.
Brenner also gave four lectures on the history of Molecular Biology, its impact on Neuroscience and the great scientific questions that lie ahead.The lectures were adapted into the book, In the Spirit of Science: Lectures by Sydney Brenner on DNA, Worms and Brains.
The "American plan" and "European Plan" were proposed by Sydney Brenner as competing models for the way brain cells determine their neural functions.According to the European plan (sometimes referred to as the British plan), the function of cells is determined by their genetic lineage. According to the American plan, a cell's function is determined by the function of its neighbours after cell migration. Further research has shown that most species follow some combination of these methods, albeit in varying degrees, to transfer information to new cells.
Brenner received numerous awards and honours, including:
Brenner was married to May Brenner (née Covitz, subsequently Balkind) from December 1952 until her death in January 2010; their children include Belinda, Carla, Stefan, and his stepson Jonathan Balkind from his wife's first marriage to Marcus Balkind. He lived in Ely, Cambridgeshire. He was an atheist.
Brenner died on 5 April 2019, in Singapore, at the age of 92.
Francis Harry Compton Crick was a British molecular biologist, biophysicist, and neuroscientist. In 1953, he co-authored with James Watson the academic paper proposing the double helix structure of the DNA molecule. Together with Watson and Maurice Wilkins, he was jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
James Dewey Watson KBE is an American molecular biologist, geneticist and zoologist. In 1953, he co-authored with Francis Crick the academic paper proposing the double helix structure of the DNA molecule. Watson, Crick and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material". In subsequent years, it has been recognized that Watson and his colleagues did not properly attribute colleague Rosalind Franklin for her contributions to the discovery of the double helix structure.
Caenorhabditis elegans is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek caeno- (recent), rhabditis (rod-like) and Latin elegans (elegant). In 1900, Maupas initially named it Rhabditides elegans. Osche placed it in the subgenus Caenorhabditis in 1952, and in 1955, Dougherty raised Caenorhabditis to the status of genus.
Howard Robert Horvitz is an American biologist best known for his research on the nematode worm Caenorhabditis elegans, for which he was awarded the 2002 Nobel Prize in Physiology or Medicine, together with Sydney Brenner and John E. Sulston, whose "seminal discoveries concerning the genetic regulation of organ development and programmed cell death" were "important for medical research and have shed new light on the pathogenesis of many diseases".
The Nirenberg and Matthaei experiment was a scientific experiment performed in May 1961 by Marshall W. Nirenberg and his post-doctoral fellow, J. Heinrich Matthaei at the National Institutes of Health (NIH). The experiment deciphered the first of the 64 triplet codons in the genetic code by using nucleic acid homopolymers to translate specific amino acids.
The Nirenberg and Leder experiment was a scientific experiment performed in 1964 by Marshall W. Nirenberg and Philip Leder. The experiment elucidated the triplet nature of the genetic code and allowed the remaining ambiguous codons in the genetic code to be deciphered.
The Human Genome Organisation (HUGO) is a non-profit organization founded in 1988. HUGO represents an international coordinating scientific body in response to initiatives such as the Human Genome Project. HUGO has four active committees, including the HUGO Gene Nomenclature Committee (HGNC), sometimes (incorrectly) referred to as "HUGO", and the HUGO Committee on Ethics, Law and Society (CELS).
Sir John Edward Sulston was a British biologist and academic who won the Nobel Prize in Physiology or Medicine for his work on the cell lineage and genome of the worm Caenorhabditis elegans in 2002 with his colleagues Sydney Brenner and Robert Horvitz. He was a leader in human genome research and Chair of the Institute for Science, Ethics and Innovation at the University of Manchester. Sulston was in favour of science in the public interest, such as free public access of scientific information and against the patenting of genes and the privatisation of genetic technologies.
The history of genetics dates from the classical era with contributions by Pythagoras, Hippocrates, Aristotle, Epicurus, and others. Modern genetics began with the work of the Augustinian friar Gregor Johann Mendel. His work on pea plants, published in 1866, established the theory of Mendelian inheritance.
The Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) is a research institute in Cambridge, England, involved in the revolution in molecular biology which occurred in the 1950–60s. Since then it has remained a major medical research laboratory with a much broader focus.
Andrew Zachary Fire is an American biologist and professor of pathology and of genetics at the Stanford University School of Medicine. He was awarded the 2006 Nobel Prize for Physiology or Medicine, along with Craig C. Mello, for the discovery of RNA interference (RNAi). This research was conducted at the Carnegie Institution of Washington and published in 1998.
Cynthia Jane Kenyon is an American molecular biologist and biogerontologist known for her genetic dissection of aging in a widely used model organism, the roundworm Caenorhabditis elegans. She is the vice president of aging research at Calico Research Labs, and emeritus professor of biochemistry and biophysics at the University of California, San Francisco (UCSF).
Apoptosis is the process of programmed cell death. From its early conceptual beginnings in the 1950s, it has exploded as an area of research within the life sciences community. As well as its implication in many diseases, it is an integral part of biological development.
John Graham White is a Professor Emeritus of Anatomy and Molecular Biology at the University of Wisconsin–Madison.
The nematode worm Caenorhabditis elegans was first studied in the laboratory by Victor Nigon and Ellsworth Dougherty in the 1940s, but came to prominence after being adopted by Sydney Brenner in 1963 as a model organism for the study of developmental biology using genetics. In 1974, Brenner published the results of his first genetic screen, which isolated hundreds of mutants with morphological and functional phenotypes, such as being uncoordinated. In the 1980s, John Sulston and co-workers identified the lineage of all 959 cells in the adult hermaphrodite, the first genes were cloned, and the physical map began to be constructed. In 1998, the worm became the first multi-cellular organism to have its genome sequenced. Notable research using C. elegans includes the discoveries of caspases, RNA interference, and microRNAs. Six scientists have won the Nobel prize for their work on C. elegans.
Leslie Barnett was a British biologist who worked with Francis Crick, Sydney Brenner, and Richard J. Watts-Tobin to genetically demonstrate the triplet nature of the code of protein translation through the Crick, Brenner, Barnett, Watts-Tobin et al. experiment of 1961, which discovered frameshift mutations; this insight provided early elucidation of the nature of the genetic code.
Jonathan Alan Hodgkin is a British biochemist, Professor of Genetics at the University of Oxford, and an emeritus fellow of Keble College, Oxford.
Julie Ann Ahringer is an American/British Professor of Genetics and Genomics, Director of the Gurdon Institute and a member of the Department of Genetics at the University of Cambridge. She leads a research lab investigating the control of gene expression.
Cell lineage denotes the developmental history of a tissue or organ from the fertilized embryo. This is based on the tracking of an organism's cellular ancestry due to the cell divisions and relocation as time progresses, this starts with the originator cells and finishing with a mature cell that can no longer divide.
Eileen Southgate is a British biologist who mapped the complete nervous system of the roundworm Caenorhabditis elegans, together with John White, Nichol Thomson, and Sydney Brenner. The work, done largely by hand-tracing thousands of serial section electron micrographs, was the first complete nervous system map of any animal and it helped establish C. elegans as a model organism. Among other projects carried out as a laboratory assistant at the Medical Research Council Laboratory of Molecular Biology (MRC-LMB), Southgate contributed to work on solving the structure of hemoglobin with Max Perutz and John Kendrew, and investigating the causes of sickle cell disease with Vernon Ingram.
