Radar plots of gene distribution per altered function. Genes significantly induced or repressed after exposure to NPs were selected as described in Table 1, Column 4. Genes were selected with fold-change ratios greater than 1.5 (n = 4, p-value ≤ 0.05), and distributed per function. This graph displays the number of significantly altered genes per function. The enlarged part concerns light-degraded Nanobyk (NB-DL) and acid-degraded Nanobyk (NB-DA). For each compound, a pattern is obtained representing the amplitude and the nature of its toxicity, then allowing a visual comparison of their respective toxicities.
