Scatter dot plot of villin (A), Nod2 (B), Tnf (C) and Nox2 (D) mRNA levels in the cecum of mice after inoculation with S. Tm. Control (Ctrl) 129 GPx1-KO and congenic Gdac1B6 GPx1-KO mice were either pre-treated with metronidazole (Met) without S. Tm inoculation or were inoculated with S. Tm without Met pretreatment. All mRNA was normalized to β-actin. The horizontal lines are mean ± SEM. N = 7–8 129 Gpx1-KO, 6–7 Gdac1-B6 Gpx1-KO, 7–8 129 Gpx2-KO, 8–9 Gdac1-B6 Gpx2-KO, 3 Ctrl 129 Gpx1-KO, 7 Ctrl Gdac1-B6 Gpx1-KO, 4 B6 WT and 3 129 WT mice for all mRNAs. Means that differ are indicated by different letters (where a>b>c). Groups share the same letter are not different (e.g cd is not different from d, bcd or ac).
