The comet assay as a tool in human biomonitoring studies: effects of confoundin...
Møller, Peter; Gajski, Goran; Gerić, Marko; Giovannelli, Lisa; Azqueta, Amaya; Haveric, Anja; Stopper, Helga; Bankoglu, Ezgi Eyluel; Collins, AndrewThe comet assay is widely used in human biomonitoring studies of environmental and occupational exposures. However, it is clear from multiple studies that various types of confounding factors might affect the direct relationship between exposure and DNA damage in the comet assay. In addition to common confounders such as age, sex, and smoking, other factors considered to be important determinants for background...
The comet assay as a tool in human biomonitoring of exposure to heavy metals: a...
Møller, Peter; Bankoglu, Ezgi Eyluel; Stopper, Helga; Gajski, Goran; Gerić, Marko; Haveric, Anja; Azqueta, Amaya; Giovannelli, Lisa; Collins, AndrewExposure to heavy metals such as lead, arsenic, and chromium is associated with genotoxicity and increased risk of cancer. In this systematic review and meta-analysis, we have assessed the effects of heavy metal exposure on levels of DNA strand breaks in leukocytes, measured by the comet assay, in human biomonitoring studies. We distinguish between traditional toxic metals (lead), semi-metals/metalloids (arseni...

Gerić, Marko; Azqueta, Amaya; Møller, Peter; Bankoglu, Ezgi Eyluel; Gajski, Goran; Giovannelli, Lisa; Haverić, Anja; Stopper, Helga; Collins, AndrewExposure to pesticides, most usually in occupational settings, is associated with different adverse health effects. In this systematic review and meta-analysis, we have assessed the effects of pesticide exposure on the level of DNA strand breaks in human peripheral blood cells, measured by the comet assay, in human biomonitoring studies. The literature search led to 80 studies included in the review. Of these, ...

Ladeira, Carina; Møller, Peter; Giovannelli, Lisa; Gajski, Goran; Haveric, Anja; Bankoglu, Ezgi Eyluel; Azqueta, Amaya; Gerić, Marko; Stopper, HelgaBiomonitoring of human populations exposed to chemical substances that can act as potential mutagens or carcinogens may enable the detection of damage and early disease prevention. In recent years, the comet assay has become an important tool for assessing DNA damage, both in environmental and occupational exposure contexts. To evidence the role of the comet assay in human biomonitoring, we have analysed origin...
Measuring DNA modifications with the comet assay: a compendium of protocols
Collins, Andrew; Møller, Peter; Gajski, Goran; Vodenková, Soňa; Abdulwahed, Abdulhadi; Anderson, Diana; Bankoglu, Ezgi Eyluel; Bonassi, StefanoThe comet assay is a versatile method to detect nuclear DNA damage in individual eukaryotic cells, from yeast to humans. The types of damage detected encompass DNA strand breaks and alkali-labile sites (e.g., apurinic/apyrimidinic sites), alkylated and oxidized nucleobases, DNA-DNA crosslinks, UV-induced cyclobutane pyrimidine dimers, some chemically induced DNA adducts. Depending on the specimen type, there ar...

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...
Collection and storage of human white blood cells for analysis of DNA damage an...
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...

Milić, Mirta; Ceppi, Marcello; Bruzzone, Marco; Azqueta, Amaya; Brunborg, Gunnar; Godschalk, Roger; Koppen, Gudrun; Langie, Sabine; Møller, PeterThe alkaline comet assay, or single cell gel electrophoresis, is one of the most popular methods for assessing DNA damage in the human population. One of the open issues concerning this assay is the identification of those factors that can explain the large inter-individual and inter-laboratory variation. International collaborative initiatives such as the hCOMET project - a COST Action launched in 2016 - repre...
