NEW YORK (September 24, 2012) Columbia University will award the 2012 Louisa Gross Horwitz Prize to Richard Losick, PhD, Joe Lutkenhaus, PhD, and Lucy Shapiro, PhD, for their collective work on the intricate, dynamic, three-dimensional organization of bacterial cells. Prior to their discoveries, the tiny bacterial cell was thought to be a "bag of enzymes" that held a jumbled mess of proteins and DNA within a "cell sap." Established in 1967, the Horwitz Prize is Columbia University's top honor for achievement in biological and biochemistry research.
The Horwitz Prize is widely considered to be a precursor to a Nobel. Of the 87 Horwitz Prize winners to date, 42 have gone on to receive Nobel prizes. To see a list of previous awardees, please click here.
"We congratulate Drs. Losick, Lutkenhaus, and Shapiro on their important work that has expanded understanding of the life of a cell and are pleased to award them our 2012 Horwitz Prize," said Lee Goldman, MD, dean of the faculties of health sciences and medicine at Columbia University Medical Center and executive vice president for health and biomedical sciences at Columbia University. "In this 45th year since the prize was established, these awardees join an elite group of scientists who have contributed greatly to the basic science that is the foundation of efforts to better understand diseases, develop new treatments, and improve the lives of patients."
"The research of these three superb pioneers has led to major insights into the biochemistry and molecular biology of the living cell. It has helped establish the simple bacterial cell as one of the most powerful models for understanding the cycle of cell life and death," said Gerard Karsenty, MD, PhD, chair of the Horwitz Prize Committee, and chair of the Department of Genetics and Development at Columbia University Medical Center.
Dr. Joe Lutkenhaus began studying the genetics of bacterial cell division in the model organism E. coli, which led to his discovery of a gene, FtsZ, which is essential for cell division. He showed that FtsZ is rate limiting for cell division and is the target of various cell division inhibitors. In a seminal Nature paper (Bi and Lutkenhaus, 1991), the localization of FtsZ is described as a ring at the future division site. This was the first demonstration in bacteria of an intracellular protein localized at a specific cellular location for a specific purpose. It also led to the discovery that bacteria contained cytoskeletal proteins, once the provenance of eukaryotic cells.
Shortly after, Drs. Shapiro and Losick published their first collaboration in Cell (1993), on the development and behavior of bacteria. Over the years, they have collaborated on eight original papers on the structure and biology of the bacterial cell, which have been published in leading peer-reviewed journals and have been influential.
Dr. Shapiro is credited with addressing the question of how one-dimensional DNA can encode and be translated into a complex three-dimensional organism. She showed, for the first time, that bacterial DNA replication occurs in a spatially organized way and that cell division depends on this spatial organization and on segregation of the DNA to opposite ends of the cell. She also showed that the cell cycle requires the precise coordination and timing of multiple biochemical and morphological events, each of which occurs at a specific stage in the cell cycle and requires the expression and function of a discrete set of genes.
In complementary work, Dr. Losick revealed the nature of three-dimensional regulation in bacterial cells, which provided a basis for understanding the properties of cellular asymmetry. He also dissected the gene regulatory mechanisms that govern systems for cellular differentiation. In addition, he discovered the interplay of spatial dynamics and regulatory mechanisms that yields morphologically differentiated cells with different cell fates.
"The contributions these three scientists have made to the fields of cell biology and microbiology make them excellent choices for the 2012 Horwitz Prize. Their visionary work has yielded novel and fundamental insights into the biochemistry and molecular biology of the living cell," said Michael Purdy, PhD, executive vice president for research, Columbia University. "In addition, letters supporting these scientists have noted their dedication to the students they have trained over the years. We are proud to honor scientists who embody a core value of Columbia Universitythe training of future generations of researchers and scientists."

The Louisa Gross Horwitz Prize was established under the will of the late S. Gross Horwitz through a bequest to Columbia University. It is named to honor the donor's mother. Louisa Gross Horwitz was the daughter of Dr. Samuel David Gross (1805-1889), a prominent Philadelphia surgeon. Gross served as president of the American Medical Association and was author of the outstanding "Systems of Surgery."
The 2012 Louisa Gross Horwitz Prize Lectures will be held on Tuesday, Nov. 20, followed by an awards ceremony. Dr. Lutkenhaus will give his lecture, "Dividing a Bacterial Cell," from 10 am in the Davis Auditorium, 530 W. 120 Street, on Columbia University's Morningside Campus.
Dr. Losick will give his lecture, "Chains, Communities and Going Green," from 12 pm in the Davis Auditorium. Dr. Shapiro will give her lecture, "Cell Cycle Regulation in a 3D Grid," from 3:30- 4:30 pm in the Alumni Auditorium, College of Physicians & Surgeons Building, 650 W. 168 Street, at Columbia University Medical Center.
