Tomas Lindahl, Swedish biochemist known for his discovery of base excision repair, a major mechanism of DNA repair, by which cells maintain their genetic integrity. Base excision repair corrects damage sustained by individual DNA bases (adenine, cytosine, guanine, and thymine), which frequently The 2015 Nobel Prize in Chemistry was awarded jointly to Tomas Lindahl, Paul Modrich and Aziz Sancar to honour their accomplishments in the field of DNA repair. Ever since the discovery of DNA structure and their importance in the storage of genetic information, questions about their stability became pertinent. Tomas Lindahl studies the operation of cellular DNA repair mechanisms and their relation to the fields of cancer therapy and inherited genetic disorders. His work has helped to measure rates of DNA decay and identify a number of proteins involved in DNA repair. Several DNA repair mechanisms have evolved to counteract such endogenous damage, including the base excision repair pathway.

This special issue is dedicated to Professor Tomas Lindahl, co-winner of the 2015 Nobel Prize in Chemistry for his seminal discoveries in the area repair of oxidatively damaged DNA. In the past several years it has become abundantly clear that DNA oxidation is a major consequence of life in an oxygen-rich environment. In his 2015 Nobel Lecture, Tomas Lindahl concluded that many more small molecules than are currently known can probably damage DNA, meaning “that there are more DNA repair enzymes waiting to be discovered”. And each and every one can be viewed as a new hope for cancer patients. Lindahl started looking for repair enzymes, using bacterial DNA, which just like human DNA consists of nucleotides with the bases adenine, guanine, cytosine and thymine.

The compilation includes genes encoding DNA repair enzymes, some genes associated with cellular responses to DNA damage, and other genes associated with genetic instability or sensitivity to DNA … 2015-10-8 · On Wednesday, the Nobel Prize in Chemistry went to three scientists who unraveled some of the secrets. Tomas Lindahl, Paul L. Modrich and Aziz Sancar were awarded the … 1999-12-3 Through biochemical studies in the 1970s, Tomas Lindahl found that DNA strands were subjected to thousands of potentially damaging influences every day. He realized that, while most of these incidents proved harmless, DNA strands failed so frequently that … Nobel Prize in Chemistry awarded to Tomas Lindahl, Paul Modrich And Aziz Sancar for research into how DNA repairs itself Scientists recognised for work on mapping how cells repair damaged DNA 2015-10-7 · The Nobel prize in chemistry has been awarded to Tomas Lindahl, Paul Modrich and Aziz Sancar for their research into the mechanisms that cells use to repair DNA… Tomas Lindahl studies the operation of cellular DNA repair mechanisms and their relation to the fields of cancer therapy and inherited genetic disorders. His work has helped to measure rates of DNA decay and identify a number of proteins involved in DNA repair. The alternative pathway of excision-repair is initiated by one of several DNA glycosylases, which catalyze cleavage of the base-sugar bond of an altered nucleotide residue to release the damaged base component in free form and leave a repairable apurinic or apyrimidinic site in the DNA. Tomas Lindahl, Paul Modrich and Aziz Sancar together won the award for their work on DNA, which mapped and explained how cells repair it and keep the genetic information around. 2016-11-7 · Tomas Lindahl shared the Nobel Prize in Chemistry in 2015 'for mechanistic studies of DNA repair' After obtaining his research doctorate, he did postdoctoral research at Princeton University and 1999-4-1 2017-2-15 · Tomas Lindahl gave a keynote presentation at the ‘‘Tomas Lindahl Conference on DNA Repair” (Figure 1), organized by his two former postdocs Drs. Yun-Gui Yang and Arne Klungland in Oslo on June 20, 2015 (Figure 2).

Lindahl realized that there must be some “fundamental DNA repair mechanisms” at work to protect cells against such a high rate of DNA damage. The discovery of the base excision repair mechanism earned Thomas Lindahl a share in the 2015 Nobel Prize in Chemistry.
