FOLKMAN, JUDAH

FOLKMAN, JUDAH (1933– ), U.S. medical scientist. Folkman was born in Cleveland, Ohio, and graduated with a B.A. from Ohio State University (1953) and an M.D. from Harvard Medical School (1957). His interest in research began while he was still an undergraduate with the development of a novel pacemaker. After training in surgery at Massachusetts General Hospital (1957–65), including service with the U.S. Navy (1960–62), he joined the staff of Harvard Medical School, where his subsequent senior appointments included professor of surgery (1967), pediatric surgery (1979), and cell biology (1994), and chief surgeon at Boston Children's Hospital. Folk-man initiated research on the importance of new blood vessels (angiogenesis) to the growth and spread of cancers. This research showed that angiogenesis is stimulated by factors produced chiefly by the specialized cells (endothelial cells) lining the interior of the blood vessels of normal individuals and by cancer cells. It also promotes inflammation in many other diseases. Angiogenesis is inhibited by naturally occurring factors and by drugs such as endostatin and angiostatin designed as the result of this basic research. He has postulated that natural anti-angiogenesis factors are an important anti-cancer defense mechanism. Anti-angiogenesis drugs have proved effective in controlling experimental cancers but their relevance to clinical medicine awaits the outcome of the many clinical trials founded on this research. His achievements have been recognized by many honors, including election to the U.S. National Academy of Sciences (1990), the Gairdner Award (1991), the Wolf Prize (1992), and the Benjamin Franklin Award (2001). In 1999 he became a member of the International Scientific Board of the Israel Cancer Association.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
