摘要：alpha-enolase (ENO1), highly expressing in cell membranes, cytoplasm and nuclei of cervical cancer and other tumors, acts as a plasminogen receptor and a glycolytic enzyme. ENO1 is found to be associated with tumorigenesis, invasion and migration, and proves to be an ideal target of tumor therapy. In this study, ENO1 monoclonal antibodies (ENO1mAb) was prepared to blockade ENO1 and the therapeutic role was observed in cervical cancer cells. First, ENO1mAb was prepared and screened by evaluating the inhibitory effect on migration and invasion of cervical cancer cells, which is supposed to block ENO1 expressed on cell membrane. Second, folic acid (FA) conjugated PLGA nanoparticles (FA-SS-PLGA) targeting tumor cells were prepared to mediate ENO1mAb entry into cells and its anti-tumor effects were investigated in vitro. We found that PLGA/FA-SS-PLGA nanoparticles-mediated ENO1mAb could antagonize the activity of ENO1 enzyme, significantly decreased the contents of lactic acid and pyruvate, and inhibited the proliferation, migration and clone formation of cervical cancer cells compared with the sham control (P < 0.05). In summary, ENO1mAb could specifically block ENO1 expressed on cell membrane and inhibit ENO1 glycolysis enzyme activity inside tumor cells, and plays a therapeutic role against cervical cancer cells. It suggests that ENO1mAb has promising anti-tumor effects.
