Joseph "Josip" Schlessinger (born 26 March 1945) is a Croatia-born Israeli biochemist and biophysician. He is chair of the Pharmacology Department at Yale University School of Medicine in New Haven, Connecticut, as well as the founding director of the school's new Cancer Biology Institute. His area of research is signaling through tyrosine phosphorylation, which is important in many areas of cellular regulation, especially growth control and cancer. Schlessinger's work has led to an understanding of the mechanism of transmembrane signaling by receptor tyrosine kinases and how the resulting signals control cell growth and differentiation.
Schlessinger was born in Topusko, Croatia, to Jewish parents. His father Imre was from Slatina, his first wife and child were deported to Auschwitz. Schlessinger mother Rivka was from Bugojno, her first husband was killed by Ustaše. Imre and Rivka Schlessinger met in a labor camp in 1943 on the island Rab. There they joined a group of Jews who joined the Yugoslav Partisans. When Schlessinger was born on 26 March 1945 he was wrapped in a British military parachute. He was named for his grandfather. After World War II the family moved to Osijek, where another son, Darko David, was born. Imre Schlessinger once joked at the expense of Josip Broz Tito and was sentenced to several months in jail. The family moved to Israel in 1948.
Schlessinger received his B.Sc. degree in Chemistry and Physics in 1968 (magna cum laude), and an M.Sc. degree in chemistry (also magna cum laude) in 1970 from the Hebrew University of Jerusalem. He obtained his PhD degree in biophysics from the Weizmann Institute of Science in 1974. From 1974–1976, he was a postdoctoral fellow in the Departments of Chemistry and Applied Physics at Cornell University in Ithaca, New York, working with Elliot Elson and Watt W. Webb. From 1977–1978, he was a visiting fellow in the immunology branch of the National Cancer Institute.
He is married to Irit Lax, an associate professor in the Pharmacology Department at Yale. They each have two children from a previous marriage.
In a 2009 interview with a Croatian daily newspaper Jutarnji list, he said, "Basically I am atheist. I grew up Jewish and I truly belong to the Jewish culture, but I'm not a follower of any world religion. Religion does not interest me at all."
Schlessinger was a member of the faculty of the Weizmann Institute from 1978–1991 and was the Ruth and Leonard Simon Professor of Cancer Research in the Department of Immunology from 1985–1991. In addition, he was a Research Director for Rorer Biotechnology in King of Prussia, Pennsylvania, from 1985–1990. In 1990, he was appointed as the Milton and Helen Kimmelman Professor and Chairman of the Department of Pharmacology at the New York University School of Medicine. He served as Director of the Skirball Institute for Biomolecular Medicine at NYU Medical Center from 1998–2001.
He has been the William H. Prusoff Professor and Chairman of the Department of Pharmacology at Yale School of Medicine since 2001. He was elected to the United States National Academy of Sciences in 2000, to the American Academy of Arts and Sciences in 2001, and to the Institute of Medicine in 2005. He is a member of the editorial boards of several journals, including Cell, Molecular Cell, the Journal of Cell Biology, and the Science magazine Science Signaling.
Awards and recognition
Schlessinger is the recipient of numerous prizes, including the Michael Landau Prize (1973), the Sara Leady Prize (1980), the Hestrin Prize (1983), the Levinson Prize (1984), a Ciba-Drew Award (1995), the Antoine Lacassagne Prize (1995), the Taylor Prize (2000), and the Dan David Prize (2006). In 2002, he was granted an honorary doctorate from the University of Haifa. In addition he has given named lectures at many institutions, including the Harvey Society (in the 1993–1994 Harvey Lectures series) and the 2006 Keith R. Porter Lecture of the American Society for Cell Biology. In 2009, he was elected as a Member of the Croatian Academy of Sciences and Arts. In 2012, the Hope Funds for Cancer Research selected Schlessinger to receive their Award of Excellence for Clinical Development. In 2009, Schlessinger was awarded with great order by President of Croatia Stjepan Mesić for outstanding service in promoting Croatia in the international scientific community and for the contribution within Croatian biomedical sciences.
He has been granted along with Charles Sawyers and Tony Hunter with the 2014 BBVA Foundation Frontiers of Knowledge Award in the Biomedicine category for “carving out the path that led to the development of a new class of successful cancer drugs.”
Publications and research
According to PubMed, Schlessinger has authored over 450 scientific original and review articles in the areas of pharmacology, molecular biology, biochemistry, and structural biology, mostly on tyrosine kinase signaling. Tyrosine kinase signaling plays a critical role in the control of many cellular processes including cell proliferation, differentiation, metabolism, as well as cell survival and migration. Tyrosine kinases play a particularly important role in cancer, and several agents that block their activity are now used as anti-cancer drugs, such as Imatinib or Gleevec. Among his contributions are the findings that cell surface receptors with tyrosine kinase activity signal across membrane by forming dimers when they bind to their growth factor activators. He discovered this in studies of the epidermal growth factor receptor (EGFR). He was also instrumental in understanding how the SH2 domain controls tyrosine kinase signaling by binding to phosphorylated tyrosines in activated receptors. One of the seminal findings in this work was his laboratory's cloning of Grb2 and other Adaptor proteins. Another is the lab's cloning of FRS2, which is critical for signaling by the Fibroblast growth factor receptor. In 2001, he was ranked by the ISI Highly Cited as one of the world's top 30 most cited scientists (across all fields) in the 1990s. According to ISI, his papers have been cited a total of 76,699 times.
In 2006, a sexual harassment lawsuit was initiated against Yale University by Schlessinger's former secretary, Mary Beth Garceau. Garceau alleged numerous episodes of harassment during her employment at Yale and claimed that Yale University failed to act upon her frequent complaints, thus causing Garceau to resign. The case was settled out of court in mid-2007 and the terms of the settlement were not publicly disclosed.
In 1991, Schlessinger co-founded (with Axel Ullrich and Steven Evans-Freke) the biotechnology company SUGEN to develop ATP-like molecules that would compete with ATP for binding to the catalytic site of receptor tyrosine kinases in cancer treatment. SUGEN later became part of Pfizer. One of the pipeline products (SU11248) was ultimately developed by Pfizer as Sutent (Sunitinib), approved by the FDA for treating gastrointestinal stromal tumors and renal cell carcinoma.
Following his involvement in SUGEN, Schlessinger co-founded Plexxikon with Sung-Hou Kim (University of California, Berkeley). Plexxikon, founded in 2001, uses a pioneering structural biology-based platform for drug discovery.
