ABSTRACT
Objective: To study the anti-tumor effect of recombinant human MUC1-MBP. Methods: The C57BL/6 mice were in oculated with MUC1-MBP by subcutaneous. MUC1 specific CTL activity of spleen were determined by MTT; The effects on prevention and treatment of tumor were observed by establishing lewis lung cancer-carrying mice. Results: The cytotoxicity of CTL from immunized mice to the MCF7 and Lewis lung cancer cells respectively was (47.7?4.3) % and (67.5 ?6.5) %; 5?10 5 lewis lung cancer cells following immunization were injected iv into C57BL/6 mice, after three weeks, the number of lung and tail tumor colonies was 51 and 5 for PBS and MUC1-MBP groups respectively and the suvival time was significantly delayed in immunized mice. The average volume of tumors in mice with MUC1-MBP was 386 mm 3 wherea control group was 4 000 mm 3 at tumor treating experiment. Conclusions: Recombinant human MUC1-MBP have significantly effects on prevention, treatment and inhibiting metastases of tumor. Our results suggested that the recombinant MUC1-MBP might be used to develop protein vaccine against human carcinoma.
