Fig 2. mRNA expression level of the acute phase response genes Saa3 in lung and Saa1 in liver 1, 3, 28 and 90 days following exposure to VC, GO, rGO and P90 (n = 7–8) at doses 0, 18, 54 and 162 μg/mouse.
Expression of mRNA was normalized to 18S rRNA and multiplied by 107. Statistical analysis for P90 compared to VC was performed separately using a t-test. *, **, ***: Statistically significantly different from corresponding VC at level p < 0.05, p < 0.01, p < 0.001, respectively.
