To investigate the immunocontraception effects of different kinds of mice and seek the relatively effective species-specific DNA vaccines, we constructed four corresponding immunocontraceptive recombinant plasmids: pcDNA3-mzp3 (pcD-M), pcDNA3-Izp3 (pcD-L), pcDNA3-aat-comp-mzp3 (pcD-ACM) and pcDNA3-aat-comp-lzp3 (pcD-ACL) using zona pellucida 3 gene of Lagurus lagurus (Lzp3) and Mus musculus (Mzp3) respectively to immunize NIH mice. With the introduction of hydrnamic transfection instead of traditional Hela cell transfection to study the genes expression in vivo, the results indicated that all four recombinants could be expressed in livers of mice; Histogram pattern of ELISA showed that all of the recombinants in mice could elicit high quantity and lasting specific anti-ZP3 antibody; Antifertility experiment showed that Mzp3 and Lzp3 groups both enhanced sterile effects (P < 0.05), especially the group of pcD-ACM had a significant difference compared with control group (P < 0.01). Histology of ovarian sections demonstrated that pcD-M and pcD-L groups had no disruption of follicular development while pcD-ACL and pcD-ACM did the opposite. The present studies proved that L. lagurus zona pellucida 3 gene (Lzp3) and M. musculus zona pellucida 3 gene (Mzp3) had immunocontraception effects and primarily presumed that they didn't possess species specificity.
