As shown in Fig. 6a, Wee1 expression levels were higher in PRRSV-infected cells than those in mock-infected cells at 24 h(1.728-fold) and 48 h(1.885-fold) post-infection, and Myt1 expression levels were also higher in PRRSV-infected cells than those in mock-infected cells at 24 h(1.249-fold) and 48 h(1.6635-fold) post-infection. This evidence concerns the gene WEE1 and infection.
