Abstract:

The aim of the present study was to find out whether ARV activates the phosphatidylinositol 3-Kinase-dependent Akt (PI3K/Akt) pathway according to the PXXP or YXXXM motif of σA and σNS protein.Gene splicing by overlap extension PCR was used to change the PXXP or YXXXM motif of σA and σNS gene.Recombined plasmids that contain mutant σA and σNS genes were generated.The Akt phosphorylation profile of transfected cells were examined by flow cytometry and Western blot.The results showed that σA and σNS genes were expressed in the Vero cells,and the expression of P-Akt of the σA mutant groups (Amino acid 110-114 and 114-117) decreased markedly.The results indicated that the σA protein of ARV activate the PI3K/Akt pathway by the PXXP motif.The results of this study reveal the mechanisms by which ARV manipulate the cellular signal transduction pathways,which may provide new ideas for novel drug targets.
