| Outline of Final Research Achievements |
In a previous study, we showed that Friend leukemia virus (FLV) envelope protein gp70 bound MCM2, impaired its nuclear translocation, and enhanced DNA-damage-induced apoptosis in hematopoietic cells when the cells expressed high levels of MCM2.
Here, we aimed to create a new cancer treatment model by interrupting the nuclear transition of MCM2 using the anti-MCM2 intrabody instead of gp70. We first conducted separation of anti-MCM2 antibody by phage display method, and were successful to separate specific antibody against MCM2. We, furthermore, confirmed that, in vitro and in vivo, this antibody connects with MCM2 in the cell and fortifies apoptosis caused by the anti-cancer drug. It is thought that, by furthering the study, this treatment by anti-MCM2 intrabody would be a model for new tumor treatments.
