Long-term cryopreservation of potassium bromate positive assay controls for mea...
Møller, Peter; Azqueta, Amaya; Rodriguez-Garraus, Adriana; Bakuradze, Tamara; Richling, Elke; Bankoglu, Ezgi Eyluel; Stopper, HelgaThe formamidopyrimidine DNA glycosylase (Fpg)-modified comet assay is widely used for the measurement of oxidatively generated damage to DNA. However, there has not been a recommended long-term positive control for this version of the comet assay. We have investigated potassium bromate as a positive control for the Fpg-modified comet assay because it generates many Fpg-sensitive sites with a little concurrent g...
DNA damage in circulating leukocytes measured with the comet assay may predict ...
Bonassi, Stefano; Ceppi, Marcello; Møller, Peter; Azqueta, Amaya; Milić, Mirta; Monica, Neri; Brunborg, Gunnar; Godschalk, Roger; Koppen, GudrunThe comet assay or single cell gel electrophoresis is the most common method used to measure strand breaks and a variety of other DNA lesions in human populations. To estimate the risk of overall mortality, mortality by cause, and cancer incidence associated with DNA damage, a cohort of 2,403 healthy individuals (25,978 person-years) screened in 16 laboratories using the comet assay between 1996 and 2016 was fo...

Møller, Peter; Bankoglu, Ezgi Eyluel; Stopper, Helga; Giovannelli, Lisa; Ladeira, Carina; Koppen, Gudrun; Gajski, Goran; Collins, AndrewDNA damage and repair activity are often assessed in blood samples from humans in different types of molecular epidemiology studies. However, it is not always feasible to analyze the samples on the day of collection without any type of storage. For instance, certain studies use repeated sampling of cells from the same subject or samples from different subjects collected at different time points, and it is desir...

Application of the comet assay in human biomonitoring: an hCOMET perspective
Azqueta, Amaya; Ladeira, Carina; Giovannelli, Lisa; Boutet-Robinet, Elisa; Bonassi, Stefano; Neri, Monica; Gajski, Goran; Duthie, SusanThe comet assay is a well-accepted biomonitoring tool to examine the effect of dietary, lifestyle, environmental and occupational exposure on levels of DNA damage in human cells. With such a wide range of determinants for DNA damage levels, it becomes challenging to deal with confounding and certain factors are interrelated (e.g. poor nutritional intake may correlate with smoking status). This review describes ...
Potassium bromate as positive assay control for the Fpg-modified comet assay
Møller, Peter; Muruzabal, Damian; Bakuradze, Tamara; Richling, Elke; Bankoglu, Ezgi Eyluel; Stopper, Helga; Langie, Sabine A.S.; Azqueta, AmayaThe comet assay is a popular assay in biomonitoring studies. DNA strand breaks (or unspecific DNA lesions) are measured using the standard comet assay. Oxidative stress-generated DNA lesions can be measured by employing DNA repair enzymes to recognise oxidatively damaged DNA. Unfortunately, there has been a tendency to fail to report results from assay controls (or maybe even not to employ assay controls). We b...
Minimum Information for Reporting on the Comet Assay (MIRCA): recommendations f...
Møller, Peter; Azqueta, Amaya; Boutet-Robinet, Elisa; Koppen, Gudrun; Bonassi, Stefano; Milić, Mirta; Gajski, Goran; Costa, SolangeThe comet assay is a widely used test for the detection of DNA damage and repair activity. However, there are interlaboratory differences in reported levels of baseline and induced damage in the same experimental systems. These differences may be attributed to protocol differences, although it is difficult to identify the relevant conditions because detailed comet assay procedures are not always published. Here...
The comet assay in animal models: from bugs to whales (Part 1: invertebrates)
Gajski, Goran; Žegura, Bojana; Ladeira, Carina; Pourrut, Bertrand; Del Bo’, Cristian; Novak, Matjaž; Sramkova, Monika; Milić, MirtaThe comet assay, also called single cell gel electrophoresis, is a sensitive, rapid and low-cost technique for quantifying and analyzing DNA damage and repair at the level of individual cells. The assay itself can be applied on virtually any cell type derived from different organs and tissues of eukaryotic organisms. Although it is mainly used on human cells, the assay has applications also in the evaluation of...
The comet assay in animal models: from bugs to whales (Part 2: vertebrates)
Gajski, Goran; Žegura, Bojana; Ladeira, Carina; Novak, Matjaž; Sramkova, Monika; Pourrut, Bertrand; Del Bo’, Cristian; Milić, MirtaThe comet assay has become one of the methods of choice for the evaluation and measurement of DNA damage. It is sensitive, quick to perform and relatively affordable for the evaluation of DNA damage and repair at the level of individual cells. The comet assay can be applied to virtually any cell type derived from different organs and tissues. Even though the comet assay is predominantly used on human cells, the...
