The phosphatase and tensin homolog gene inserted between NP and P gene of recombinant New castle disease virus oncolytic effect test to glioblastoma cell and xenograft mouse model.

Background: Glioblastoma is one of the most serious brain cancer. Previous studies have demonstrated that PTEN function disorder affects the causing and exacerbation of glioblastoma. Newcastle disease virus (NDV) has been studied as a cancer virotherapeutics.

Replacing the decoy epitope of PCV2 capsid protein with epitopes of GP3 and/or GP5 of PRRSV enhances the immunogenicity of bivalent vaccines in mice.

Porcine circovirus type 2 (PCV2) is the causative agent of postweaning multisystemic wasting syndrome (PMWS), porcine dermatitis and nephropathy syndrome (PDNS), and reproductive failure and causes economic losses in the domestic swine industry. The decoy epitope (169-180 amino acid (aa)) of the PCV2 capsid (Cap) protein is an immunodominant epitope and diverts the immune response away from protective epitopes. The mixed infection of PCV2 and porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most common co-infections in the pig industry and shows more severe clinical symptoms.
