Paul Zamecnik
Paul Charles Zamecnik (born November 22, 1912 in Cleveland , Ohio , † October 27, 2009 in Boston , Massachusetts ) was an American biochemist and molecular biologist .
Live and act
Zamecnik earned a bachelor's degree in chemistry and zoology from Dartmouth College in 1933 and an MD from Harvard Medical School in 1936 as a medical degree. As a resident he worked in Pasadena , Cleveland and Boston . As a postdoctoral fellow , Zamecnik worked at the Carlsberg Research Center in Copenhagen and at the Rockefeller Institute in New York City , before teaching at Harvard Medical School from 1942 .
In 1953 Paul Zamecnik developed a cell-free system for protein synthesis , the metabolic pathways of which could be explored with 14 C -labelled amino acids . This paved the way for the discovery that proteins are synthesized from a blueprint in DNA . Zamecnik was also able to show that protein synthesis consumes adenosine triphosphate (ATP) and is not a reverse reaction to proteolysis . Between 1956 and 1979, Zamecnik was a professor at Harvard Medical School and a doctor at Massachusetts General Hospital in Boston. In 1956, together with Mahlon Hoagland and Mary Stephenson , Zamecnik identified tRNA (transfer RNA) for the first time , which controls the selection of the next correct amino acid based on the genetic code . He was also able to show that the process of protein synthesis takes place on the ribosomes .
He developed the idea of using antisense oligonucleotides to block the activity of certain genes - for example from tumors or viruses - and thus the synthesis of pathogenic proteins, and in 1978 he published the method. In 1979 Zamecnik moved to the Worcester Foundation for Biomedical Research , when he reached the age limit at Harvard University , where successful applications of the antisense method were realized. a. against the human immunodeficiency virus (HIV). In 1990 Zamecnik founded the biotechnology company Hybridon . In 1997, the Worchester Foundation merged with the University of Massachusetts Medical School and Zamecnik's laboratory moved to Massachusetts General Hospital in Boston, where he worked in research until a few weeks before his death.
Zamecnik was married and had three children.
