ABSTRACT
Objective To construct MUC1-VNTR DNA vaccine pancreatic cancer. Methods The recombinant gene of VNTR was synthesized and cloned into MCS in the pcDNA3. 1/Myc-his ( + ) A vector. pcDNA3. 1-VNTR/Myc-his( + ) A was injected twice into C57BL/6( H-2b)female mice (V group, n = 15). Mice inoculated with either the empty plasmid vector ( D group, n = 15 ) or 0. 9% NaCl ( NS group, n, = 15) were used as control. Two weeks later, both humoral and cellular immunity of the mice were studied. Results The recombinant plasmid pcDNA3. 1 -VNTR/Myc-his ( + ) A encoded the whole exact translation frame region of the pcDNA3. 1/Myc-his ( + ) A vector and the recombinant gene of human VNTR. The transfected COS7 cells expressed transgene products at 48 hours after transfection. Intramuscular delivery of the recombinant plasmid into C57BL/6 mice resulted in more efficient induction of CTL lysis specific against VNTR polypeptide than the D group and the NS group (P
