^{a}The raw *p*-values were subjected to multiple testing correction using FDR-adjusted *p*-value; Statistically significant difference among groups at p < 0.05 by One-way ANOVA are highlighted in bold- Values are expressed as mean ± SE (b) and Median (minimum - maximum) (c)
^{*, **, ***} Statistically significant difference from corresponding low- exposed group at *p* < 0.05, < 0.01 and < 0.001, respectively by Mann-Whitney U test
