In contrast, WSN induced more N-cadherin (Figure 3B), β-catenin (Figure 3C), vimentin (Figure 3D), snail (Figure 3E), cyclin D (Figure 3F), PPAR (Figure 3G), TCF-1 (Figure 3H), and TGF-β (Figure 3I) expression than Yamagata at 12 and/or 24 h after virus infection. Here, PPARA is linked to viral infectious disease.
