Western blot analysis of DNMT1 (A), DNMT3A (B), DNMT3B (C) and MeCP2 (D) protein levels in liver tissue of mice exposed to whole heat-killed <i>E. coli</i> O157:H7 bacteria and DNA, RNA, protein, and LPS extracted from heat-killed bacteria.

<p>Bars show the average protein levels (with SD) as compared to the control set at 100%. Asterisks and bars show significant increase from non-exposed controls through the analysis of data using one way ANOVA test (p<0.05). Lower panel shows representative Western blots in 2 and 4 weeks groups.
