  The expression profile of genes involved in oxidative stress, metal toxicity, apoptosis/cell cycle, and protein folding was investigated in liver and testis of Sprague-Dawley rats at different time intervals after i.t. instillation of AgNP (20 nm, 50 μg/rat). At 7 days, selective changes in the expression of genes encoding oxidative stress-related enzymes, namely Gpx1, SOD, FMO2 and GAPDH were observed in hepatic and testicular tissues. Other genes implicated in oxidative stress (Txnrd1, Gss, Gsr), metal toxicity (Mt1), apoptosis/cell cycle (casp3, p53), and protein-folding processes (Hsp70) were not modified. Gene expression was modulated by AgNPs in a tissue- and time-dependent manner. In particular, SOD was up-regulated in both tissues, but significant Gpx1, FMO2, and GAPDH overexpression was seen i..
