abstract：:Carbon nanotubes (CNTs) are fibrous carbon-based nanomaterials with a potential to cause carcinogenesis in humans. Alterations in DNA methylation on cytosine-phosphate-guanidine (CpG) sites are potential markers of exposure-induced carcinogenesis. This study examined cytotoxicity, genotoxicity and DNA methylation alte...
