A regulatory perspective on the applicability of NAMs in genotoxicity and carci...
Bossa, Cecilia; Alivernini, Silvia; Andreoli, Cristina; Aquilina, Gabriele; Attias, Leonello; Benfenati, Emilio; Dusinska, Maria; El Yamani, NaoualeNew Approach Methodologies (NAMs) are gaining significant momentum globally to reduce animal testing and enhance the efficiency and human relevance of chemical safety assessment. Even with substantial EU commitment from regulatory agencies and the academic community, the full regulatory adoption of NAMs remains a distant prospect. This challenge is further complicated by the fact that the academic world, orient...

A critical review to identify data gaps and improve risk assessment of bispheno...
Mhaouty-Kodja, Sakina; Zalko, Daniel; Tait, Sabrina; Testai, Emanuela; Viguié, Catherine; Corsini, Emanuela; Grova, Nathalie; Buratti, Franca MariaBisphenol A (BPA), a synthetic chemical widely used in the production of polycarbonate plastic and epoxy resins, has been associated with a variety of adverse effects in humans including metabolic, immunological, reproductive, and neurodevelopmental effects, raising concern about its health impact. In the EU, it has been classified as toxic to reproduction and as an endocrine disruptor and was thus included in ...
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...

Hazard Assessment of Benchmark Metal-Based Nanomaterials Through a Set of In Vi...
Vital, Nádia; Pinhão, Mariana; Yamani, Naouale El; Rundén-Pran, Elise; Louro, Henriqueta; Dušinská, Maria; Silva, Maria JoãoFor safety assessment of nanomaterials (NMs), in vitro genotoxicity data based on welldesigned experiments is required. Metal-based NMs are amongst the most used in consumer products. In this chapter, we report results for three metal-based NMs, titanium dioxide (NM- 100), cerium dioxide (NM-212) and silver (NM-302) in V79 cells, using a set of in vitro genotoxicity assays covering different endpoints: the medi...
