HMS Professor Stephen Harrison to Receive 48th Rosenstiel Award

Prof. Stephen C. Harrison will receive the 48th Rosenstiel Award for Distinguished Work in Basic Medical Research on March 25, 2019. He is being honored for his studies of protein structure using X-ray crystallography.  His work has ranged from the landmark elucidation of the structure of viruses, to understanding the recognition of DNA sequences by transcription factors, to the regulation of protein kinases implicated in cancer. The event will take place from 4:00 to 5:00 PM on Monday, March 25 in Gerstenzang 123.

Harrison is the Giovanni Armenise-Harvard Professor of Basic Medical Sciences and Director of the Center for Molecular and Cellular Dynamics at the Harvard Medical School.  He is also Head of the Laboratory of Molecular Medicine at Boston Children’s Hospital and an Investigator of the Howard Hughes Medical Institute.   He has been elected a member of the US National Academy of Sciences, the American Academy of Arts and Sciences,  the American Philosophical Society; he is a foreign member of the Royal Society and the European Molecular Biology Organization.

Dr. Harrison’s initial studies of virus structure provided an understanding of how viruses invade cells and how virus particles are assembled.  He has extended his work to reveal the structures of many viruses, including influenza, HIV, ebola and dengue.  Knowledge of these structures is guiding the development of new vaccines against these viruses.  Moreover, the methodology that he and his colleagues developed to visualize virus structure has made it possible to learn about the molecular architecture of other very large assemblies of proteins.

Harrison’s lab has also revealed the ways that proteins recognize specific DNA sequences to regulate gene expression.  More recently his lab has been exploring the complex structure of the many proteins that are assembled in the kinetochore, which anchors the centromeres of chromosomes to microtubules, to permit their proper segregation in mitosis.

“Steve Harrison has done much more than giving us astonishing pictures of proteins at the atomic level; he has used this structural information to show us how these proteins perform their precise functions,” said James E. Haber, Director of the Rosenstiel Center for Basic Medical Sciences.

The Rosenstiel Award has had a distinguished record of identifying and honoring pioneering scientists who subsequently have been honored with the Lasker and Nobel Prizes. Awards are given to scientists for recent discoveries of particular originality and importance to basic medical research.

Titia de Lange to receive 47th Rosenstiel Award

Professor Titia de Lange

The 47th Lewis S. Rosenstiel Award for Distinguished Work in Basic Medical Research has been awarded to Professor Titia de Lange of Rockefeller University for her studies on the protection of chromosome ends (telomeres) from degradation and rearrangement. Professor de Lange will receive the award on April 12, 2018 at Brandeis University where de Lange will present a public lecture.

Dr. de Lange’s laboratory identified and characterized the roles of proteins that compose the shelterin complex, which binds specifically to the special telomeric DNA sequences and maintains the stability of these ends.  Dr. de Lange’s work has shown that the shelterin complex and the unusual telomere-loop structure of telomere DNA prevent these ends from being detected as broken chromosome ends and thus protect telomeres from being degraded and rearranged as are the ends at chromosome breaks.  De Lange’s work has further shown that disabling different components of shelterin triggers different cellular alarms designed to detect broken and degraded DNA ends and leads to lethal chromosome rearrangements such as the fusion of chromosomes.  In addition, her lab has gained critical insights into the mechanisms of cellular response to the presence of DNA damage and recently has defined processes that lead to massive chromosome rearrangements (chromothripsis) associated with many human cancers.

She is the Leon Hess Professor and director of the Anderson Center for Cancer Research at Rockefeller University, as well as an American Cancer Society Research Professor.  Her honors include: the Life Sciences Breakthrough Prize, the Rosalind E. Franklin Award from the National Cancer Institute, the Vilcek Prize in Biomedical Sciences, election as a foreign member of the US National Academy of Sciences and as Fellow of the American Academy of Arts and Sciences.

The Rosenstiel Award has had a distinguished record of identifying and honoring pioneering scientists who subsequently have been honored with the Lasker and Nobel Prizes.  Professor de Lange joins a long list of past awardees.

Rosenstiel Award lectures on Mar 22 to honor Susan Lindquist

James Haber, Director of the Rosenstiel Center, writes:

The 46th annual Rosenstiel Award for Distinguished Work in Basic Medical Research was awarded last October to Susan Lindquist (MIT), one of the most inventive and influential life scientists of our generation.  Sue tragically passed away a few weeks thereafter; in her honor we have arranged a symposium to celebrate her lab’s great legacy.  The Award talks will be held in next Wednesday, March 22, in Gerstenzang 123 from 3:30 PM to 5:30 PM, followed by a reception open to all in the Shapiro Science Center atrium.  We hope you will all come to honor Sue Lindquist and to be edified by the excellent work carried out by her former colleagues.

Rosenstiel Award 2012- Dr. Steven J. Elledge

The 2012 Rosenstiel award is being awarded to Dr. Steven J. Elledge of Harvard University and the Howard Hughes Medical Institute for his seminal contributions towards understanding the eukaryotic DNA damage response[1] [2] .
Cells are constantly challenged by damage to their DNA. It of no surprise therefore, that both prokaryotic and eukaryotic cells have evolved sophisticated and remarkably complex responses to deal with damaged DNA. It is for elucidating these mechanisms that Dr. Elledge is being honored with the Rosenstiel award this year.
Dr. Elledge’s interest with the DNA damage response began as a graduate student at MIT in the laboratory of Graham Walker, where he identified and cloned genes involved in DNA repair mechanism known as the SOS reponse in the bacterium E.coli[3, 4] . It was during this time that Dr. Elledge also invented an extremely useful molecular biology tool known as ‘phasmids’ which allowed for the ability to rapidly clone E.coli genes by packaging them in phages[5].
After MIT, Dr Elledge began his postdoctoral work at Stanford University where he discovered the Ribonucleotide reductase(RNR) genes in budding yeast[6, 7]. These genes are induced following DNA damage to promote the synthesis of deoxyribonucleotides which helps facilitate DNA repair. Dr. Elledge followed up on this work as a professor at Baylor University by a series of important papers that shed light on how cells arrest division after DNA damage. Most notably in 1994, his group identified the Rad53 checkpoint kinase that is activated after DNA damage and contributes to cell cycle arrest [8]. In 1998, his group also identified the mammalian homolog of Rad53 (Chk2) [9, 10].In 1999, the Elledge group reported that the DNA damage checkpoint in yeast occurs in two parallel pathways laying the foundation of our understanding of the DNA damage checkpoint[11]. More recently, work from the Elledge lab identified novel factors in the DNA damage response by performing a siRNA screen in mammalian cells[12].
Dr Steve Elledge has been an investigator of the Howard Hughes Medical Institute since 1993. In 2003 he moved to Harvard Medical School as Professor in the Departments of Genetics and as a Geneticist in the Department of Medicine, Brigham and Women’s Hospital. Dr. Elledge was elected in 2003 to both the U.S. National Academy of Sciences and the American Academy of Arts and Sciences. In addition to the Rosenstiel award, he has received the DAMD Breast Cancer Innovator Award (2003), the National Academy of Sciences Award in Molecular Biology (2002), the John B. Carter, Jr. Technology Innovation Award (2002), and the Paul Marks Prize for Cancer Research (2001[2]).

Editor’s Note: On Mar 20, 2013, Elledge was named to receive a 2013 Canada Gairdner International Award.

Elledge wins Rosenstiel Award

Professor Stephen J. Elledge of the Harvard Medical School and the Howard Hughes Medical Institute has been awarded the 42nd Rosenstiel Award For Distinguished Work in Basic Medical Science  for “elucidating how eukaryotic cells sense and respond to DNA damage”. He identified key DNA damage response genes both in yeast and mammalian cells, showed how the pathway is activated by DNA lesions, and made key contributions to defining the cascade of phosphorylation events that enforces cell cycle arrest and controls DNA repair. Dr. Elledge’s work is also marked by the development of powerful research tools to uncover the network of genes involved in sensing and repairing DNA damage. His pioneering work laid the foundation for our current understanding of how failures in DNA damage sensing relate to the medically important field of genome instability.

The Rosenstiel Award consists of a cash prize and a medal, to be awarded at a dinner at Brandeis on March 14, 2013.
