    摘要: A method for treating cancer in mammals using an expression vector to transfect cancer cells in vivo and in situ. The vector includes one or more immunogenic exogenous polypeptides that are expressed by the cancer cells upon transfection. The body's immune response is triggered and directed to attack the transfected cancer cells. Once the immune response to the exogenous peptide on the cancer cells is initiated, an immune response to the other cancer associated or cancer specific antigens on or in the cancer cells takes over and eliminates all cancer cells, transfected or not.

    摘要: Processes vectors and engineered cell lines for large-scale transfection and protein production in mammalian cells, especially Chinese Hamster Ovary (CHO) cells are described in which transfection efficiencies are realized through the use of a single vector system, the use of functional oriP sequences in all plasmids, the use of codon-optimized Epstein-Barr virus nuclear antigen-1 (EBNA1) constructs the use of a fusion protein between a truncated Epstein-Barr virus nuclear antigenen-1c (EBNA1c) protein and a herpes simplex virus protein VP16, the use of a 40 kDa fully deacetylated poly(ethylenimine) as a transfection reagent, the use of co-expression of a fibroblast growth factor (FGF) and/or the use of protein kinase B to potentiate heterologous gene expression enhancement by valproic acid (VPA).
