Abstract:

This study was conducted to find out the avian reovirus (ARV) proteins which can activate the phosphatidylinositol 3-Kinase-dependent Akt(PI3K/Akt) pathway.According to the analysis of amino acid sequence of ARV proteins,the σA,σNS,μA,μB and μNS were selected as the putative proteins which mediated the activation of PI3K/Akt pathway.Reconbinant plasmids,σA-pcAGEN,σNS-pcAGEN,μA-pcAGEN,μB-pcAGEN and μNS-pcAGEN were constructed and transfected into Vero cells,and the expression of the target genes were identified by immunofluorescence test and Western blot.The phosphorylated Akt (P-Akt) profile of transfected cells were examined by flow cytometry and Western blot.The results showed that σA,σNS,μA,μB and μNS genes were expressed in the Vero cells,and the expression of P-Akt of σA-pcAGEN and σNS-pcAGEN groups increased markedly.The PI3K inhibitor LY294002 could inhibit the expression of the P-Akt of σA-pcAGEN and σNS-pcAGEN groups.The results indicate that σA and σNS protein could activate the PI3K/Akt pathway.
