Expression of TGF-β1 and TGF-β1 receptor.

<p>Liver lysates obtained from the NZB/W F1 mice receiving PBS, NS1, VP1u or VP2 were probed with antibodies against (A) TGF-<i>β</i>1 and TGF-β1 receptor, respectively. Bars represent the relative protein quantification of (B) TGF-β1 and (C) TGF-β1 on the basis of β-actin. Serum level of (D) TGF-β1 was determined using an EIA kit. Similar results were observed in three independent experiments, and * indicates the significant difference, P<0.05.
