Differentially expressed probe sets and persistent changes in expression following Cd or Cr exposure in the liver.

<p>Venn diagrams of (A) total probe sets from all time points for each metal and (B) probe sets on each day included for enrichment analysis. Probe sets were considered significant with a fold-change ≥ 1.8 or ≤ -1.8 and either an FDR < 0.05 (day 1) or unadjusted <i>p</i>-value < 0.05 (days 3 and 7).</p>
