Expression of MMP9 and uPA. Liver lysates obtained from the NZB/W F1 mice receiving PBS, NS1, VP1u or VP2 were probed with antibodies against (A) MMP9 and (B) uPA.

<p>Bars represent the relative protein quantification of (A) MMP9 and (B) uPA on the basis of β-actin. Similar results were observed in three independent experiments, and * indicates the significant difference, P<0.05.
