DNA single-strand break repair and spinocerebellar ataxia with axonal neuropathy-1 [PDF]

, 2007
DNA single-strand breaks (SSBs) are the commonest DNA lesions arising spontaneously in cells, and if not repaired may block transcription or may be converted into potentially lethal/clastogenic DNA double-strand breaks (DSBs).

Fluorescence in situ hybridization in combination with the comet assay and micronucleus test in genetic toxicology

Molecular Cytogenetics, 2010
Comet assay and micronucleus (MN) test are widely applied in genotoxicity testing and biomonitoring. While comet assay permits to measure direct DNA-strand breaking capacity of a tested agent MN test allows estimating the induced amount of chromosome and/

Modification of comet-FISH technique by using temperature instead of chemical denaturation

MethodsX, 2014
Comet-FISH technique is an extension of commonly used comet assay. Its purpose is to determine whether primary DNA damage which comet assay detects occurred within a sequence of interest that is visualized by hybridization of fluorescent probe.

The Comet Assay: Tails of the (Un)expected. Use of the comet assay in pharmaceutical development.

Frontiers in Genetics, 2015
In genotoxicity testing of pharmaceuticals the rodent alkaline comet assay is being increasingly used as a second in vivo assay in addition to the in vivo micronucleus assay to mitigate in vitro positive results as recommended by regulatory guidance.

Genotoxicity assessment of piperitenone oxide: an in vitro and in silico evaluation [PDF]

, 2017
Piperitenone oxide, a natural flavouring agent also known as rotundifolone, has been studied for the genotoxicity assessment by an integrated in vitro and in silico experimental approach, including the bacterial reverse mutation assay, the micronucleus ...

Closing the gap: from public concerns about health effects to science-based testing of chemicals

Frontiers in Genetics, 2015
The comet assay is a powerful technology for measuring DNA integrity in humans and other organisms at the level of individual cells. The assay is used for research and industrial testing but suffers from a lack of standardisation, which hinders its use ...

Quantitation of intracellular NAD(P)H can monitor an imbalance of DNA single strand break repair in base excision repair deficient cells in real time [PDF]

, 2003
DNA single strand breaks (SSBs) are one of the most frequent DNA lesions in genomic DNA generated either by oxidative stress or during the base excision repair pathways.

The basic principles of DNA damage detection by the alkaline comet assay [PDF]

Arhiv za farmaciju
The Comet assay is a highly sensitive and rapid method for detecting DNA damage at the level of individual cells. It measures single-stranded and double-stranded DNA breaks, alkali-labile, incomplete excision repair and cross-linking sites.
