  1. Note: aSig = significance, statistical test of expression difference. *Statistically significant; bthe number indicates the fold change of the differential proteins. The four sample pairwise comparisons were as follows: 12 h with 0 mM vs.1 mM Mn(II), 1-vs-2; 48 h with 0 mM vs. 1 mM Mn(II), 3-vs-4; 12 h vs.48 h with 0 mM M (II), 1-vs-3; and 12 h vs.48 h with 1 mM Mn(II), 2-vs-4. The bold values represent up-regulated expression (>1.2 fold).
