Paul Charles Zamecnik (November 22, 1912 – October 27, 2009) was an American scientist who played a central role in the early
history of molecular biology. He was a professor of medicine at
Harvard Medical School and a senior scientist at
Massachusetts General Hospital

he co-discovered
transfer RNA
Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino ac ...
(tRNA). Through his later work, he is credited as the inventor of
antisense therapeutics
Antisense therapy is a form of treatment that uses antisense oligonucleotides (ASOs) to target messenger RNA (mRNA). ASOs are capable of altering mRNA expression through a variety of mechanisms, including ribonuclease H mediated decay of the pre-m ...
. Throughout his career, Zamecnik earned over a dozen US patents for his therapeutic techniques. Up until his death in 2009 he maintained a lab at MGH where he studied the application of synthetic oligonucleotides (antisense hybrids) for chemotherapeutic treatment of drug resistant and XDR tuberculosis in his later years.
Education and research
Paul Zamecnik was born in
Cleveland, Ohio

to John Charles Zamecnik (1879-1930) and Mary Gertrude Mccarthy (1883-1937). John's first cousin was the composer
John Stepan Zamecnik. Paul's paternal grandparents Jan Nepomucký Zámečník (1842-1915) and Konstancie Hrubecká (1843-1924) were
Czech immigrants from
Budičovice and
Skály respectively. His mother's parents were
Irish immigrants. He attended
Dartmouth College, majored in
chemistry

zoology, and received his AB degree in 1933. He then attended
Harvard Medical School and received his MD degree in 1936. Between 1936 and 1939, he worked at
Collis P. Huntington Memorial Hospital in Boston, Harvard Medical School, and Lakeside Hospital in Cleveland.
During his Lakeside Hospital internship, Zamecnik became interested in how cells regulate growth, and hence, in
protein chemistry. He was awarded a Finney-Howell Fellowship and a Moseley Traveling Fellowship to go to the
Carlsberg Laboratory in Copenhagen where he worked with Dr.
Kai Linderstrom-Lang. His planned time in Copenhagen was cut short because of
World War II—the Germans occupied Denmark from April 1940—and he and his wife, Mary Connor, returned to Boston where he became an Assistant Physician at the Huntington Memorial Hospital, studying the toxic factors involved in
traumatic shock
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, fast heart rate, fast breathing, sweating, anxiety, and increased thi ...

, he returned to Harvard in 1942 to join the Faculty of Medicine at Harvard Medical School where he became Instructor and then Professor of Medicine, where he served until retiring as the Collis P. Huntington Professor of Oncologic Medicine, Emeritus in 1979.
After retiring from Harvard Medical School he continued his research at the Worcester Foundation for Biomedical Research with his former colleague Dr. Hoagland. When the foundation merged with the University of Massachusetts Medical School in 1997, Dr. Zamecnik moved his laboratory to MGH, where he continued to work until several weeks before his death.
Paul Zamecnik is generally regarded as the founder of
antisense therapy.
Zamecnik authored or co-authored 210 peer-reviewed scientific articles. He won many distinguished awards, including the
National Cancer Society
