- Minimum Information for Reporting on the Comet Assay (MIRCA): recommendations for describing comet assay procedures and resultsPublication . Møller, Peter; Azqueta, Amaya; Boutet-Robinet, Elisa; Koppen, Gudrun; Bonassi, Stefano; Milić, Mirta; Gajski, Goran; Costa, Solange; Teixeira, João Paulo; Costa Pereira, Cristiana; Dusinska, Maria; Godschalk, Roger; Brunborg, Gunnar; Gutzkow, Kristine B.; Giovannelli, Lisa; Cooke, Marcus S.; Richling, Elke; Laffon, Blanca; Valdiglesias, Vanessa; Basaran, Nursen; Del Bo’, Cristian; Zegura, Bojana; Novak, Matjaz; Stopper, Helga; Vodicka, Pavel; Vodenkova, Sona; de Andrade, Vanessa Moraes; Sramkova, Monika; Gabelova, Alena; Collins, Andrew; Langie, Sabine A.S.The 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, we present a Consensus Statement for the Minimum Information for Reporting Comet Assay (MIRCA) providing recommendations for describing comet assay conditions and results. These recommendations differentiate between 'desirable' and 'essential' information: 'essential' information refers to the precise details that are necessary to assess the quality of the experimental work, whereas 'desirable' information relates to technical issues that might be encountered when repeating the experiments. Adherence to MIRCA recommendations should ensure that comet assay results can be easily interpreted and independently verified by other researchers.
- Mutagenic and carcinogenic potential of metal nanoparticles depends on their physicochemical propertiesPublication . Dusinska, Maria; El Yamani, Naouale; Fjellsbø, Lise Maria; Huk, Anna; Gabelova, Alena; Alonso, Tamara Iglesias; Silva, Maria João; Pran, Elise RundenNanomaterials (NMs) and nanoparticles (NPs) have been studied intensively for almost two decades and still all the characteristics that might be beneficial or harmful are not explored. Although many studies have investigated the mechanisms of action of NPs in cells, results are not fully understood and in many cases are controversial. Endpoints appropriate for detecting harmful chemicals such as cytotoxicity, oxidative stress, inflammation, immunotoxicity, genotoxicity, and in some cases carcinogenicity, have been addressed. However, there might be also new mechanisms that might lead to NM-induced toxic effects.
