DNA is constantly damaged by various endogenous and exogenous events. Repair systems constantly scan the genome for DNA lesions and replace damaged and mismatched bases, which finally enables the complex DNA double strand to store genetic information. This year's Nobel Prize in Chemistry was awarded to pioneers in this field, T. Lindahl, P.

DNA Glycosylases in DNA Repair [PDF]
, 1986 The excision of potentially mutagenic and lethal lesions from DNA proceeds by one of two different routes. DNA damage which results in a major distortion of the DNA double-helix is generally recognized by a high-molecular weight nuclease that cuts two phosphodiester bonds in the altered strand, one on each side of the lesion.

Annual Review of Biochemistry, 1996
Eukaryotic cells have multiple mechanisms for repairing damaged DNA. 06-methylguanine-DNA methyltransferase directly reverses some simple alkylation adducts. However, most repair strategies excise lesions from DNA. Two major pathways are base excision repair (BER), which eliminates single damaged-base residues, and nucleotide excision repair (NER ...

Nature Cell Biology, 2015 A new study suggests that fumarase, a metabolic enzyme normally associated with ATP production in mitochondria, is recruited to sites of DNA damage where it produces fumarate to inhibit histone demethylation and promote repair of DNA double strand breaks.

Current Opinion in Structural Biology, 1997
Recent crystallographic studies of DNA-repair enzymes have provided the structural basis for the recognition of damaged DNA. The results imply that flipping out of the base is a common and crucial event in DNA repair. Two classes of repair enzymes that recognize distinct types of damage may exist.

Journal of Dermatological Science, 2008
The incidence of sunlight-induced skin changes (photoaged skin, skin carcinogenesis) increases with increasing age and it is thought to be associated with an accumulation of mutations in skin cells. These mutations are mainly caused by UV exposure. The reactive oxygen species produced in UV-exposed skin can cause various kinds of DNA damages e.g., 8 ...

AbstractIn vivo DNA damage impacts the genetic stability of an organism; therefore, multiple pathways utilizing a large number of enzymes have evolved to repair DNA damage. This unit focuses on enzymes involved in base excision repair (BER). The BER enzymes possessing N‐glycosylase activity can find and remove a wide variety of damaged bases in a sea ...

Clinics in Haematology, 1980
A number of disparate clinical syndromes have been loosely grouped together under the leading of diseases of DNA repair. More logically they should perhaps be termed diseases of diminished capacity to cope with DNA damage, since in only three has defective DNA repair been established as a basis so far.
