ABSTRACT
Objective To investigate the effects of monoclonal antibody against stathmin 1 in combination with vinblastine on the proliferation of K562 cells. Methods K562 cells were treated with monoclonal antibody against stathmin 1, vinblastine alone or with their combination, 24, 48, 72, 96 hours later, inhabitation rate was studied by MTT assay;The apoptosis was analyzed by invert microscope and flow cytometry with Annexin V/PI. Results The quantity decreased and shape, size changed after treatment with different concentration of experimental groups. Monoclonal antibodies against stathmin 1 and vinblastine used alone or in combination both inhibited the proliferation of K562 cells,the inhibition ratio of their combination is higher (P <0. 05) ,and a synergistic effect of the two agents was noted in their combined action ( P < 0. 05 ). Combined treatment of the cells resulted in significantly higher apoptsis rate than that in the other groups (P <0. 05). Conclusion Monoclonal antibody against stathmin 1 and vinblastine used alone or in combination both can inhibite proliferation of K562 cells and induce apoptsis. A synergistic effect is observed between the monoclonal antibodies against stathmin 1 and vinblastine in their inhibition of K562 cell proliferation.
