  • Title: [Construction of a DNA vaccine against human B cell lymphoma].
    Author: Zhang YS, Zhong KL, Yuan Y, Zhang MW, Zhang Y, Mao N.
    Journal: Xi Bao Yu Fen Zi Mian Yi Xue Za Zhi; 2004 Jan; 20(1):79-82. PubMed ID: 15182628.
    Abstract:
    AIM: To construct a DNA vaccine based on surface Ig V(H) gene of tumor cells in the human B-cell lymphoma biopsy tissue. METHODS: The V(H) gene fragment was amplified by RT-PCR using Ig superfamily primers. Also, the murine monocyte chemotactic protein 3(MCP-3) cDNA was cloned. The fusion gene fragment of MCP-3 gene with V(H) gene was constructed by recombinant PCR and then cloned into the eukaryotic expression vector pcDNA3.1 to construct the DNA vaccine plasmid pcDNA3.1/MCP-V(H). The vaccine plasmid was transiently expressed in the eukaryotic cell line COS-7. RESULTS: The DNA vaccine plasmid was successfully constructed and expressed in COS-7 cells in the form of fusion protein MCP-V(H). CONCLUSION: The DNA vaccine plasmid pcDNA3.1/MCP-V(H) is constructed and expressed successfully, which plays the foundation for further experimental research in animal model.
