Differentially expressed genes in silver-treated zebrafish embryos. (a). The number of differentially expressed genes (adjusted P values <0.05) as a result of the various silver treatments (AgNP, Ag bulk and Ag⁺) compared to the controls. Percentages of up- and down-regulated genes for each of the silver treatments are indicated on the bars. (b, c). Venn-diagram showing the overlap between sets of differentially expressed genes obtained for each of the silver treatment libraries after 24 (b) and 48 (c) hours of exposure.
