Nanotechnology presents a wide range of biotechnological and biomedical applications which offer the possibility to achieve great improvements in social welfare and other fields. However, any application of nanomaterials (NMs) must demonstrate its safety for human health and the environment before their applications receive approval for use. Due to the size of NMs, which have at least one dimension smaller than 100 nm, their properties cannot be extrapolated from equivalent materials in non-nanometric scale. For this reason, a case-by-case safety study is needed. Indeed, the large amount of NMs currently available and potentially usable is an obstacle to their immediate implementation. NMs are known to produce cytotoxicity, genotoxicity and oxidative stress, processes that might lead to neurodegeneration. This project seeks to analyse the effects in the transcriptome of human glioblastoma T98G cells of silver nanoparticles. The exposure of T98G cells to silver nanoparticles at a non-cytotoxic concentration caused statistically significant alterations in the expression of 43 genes, which belonged to different terms of each of the three subcategories of the gene ontology. Twelve different metabolic pathways were also altered with these 42 genes, being neuroinflammation and the signalling pathway of fibroblast growth factor those with a more evident physiological relevance.
