OBJECTIVE: To investigate the effects of Nocardia rubra cell wall skeleton (Nr-CWS) on the HeLa cell line, one of the cell lines of human cervical cancer, infected with HPV. METHODS: HPV-infected HeLa (HPV 18-positive cells) cultured in vitro were divided into two groups: the experiment group and control group. Nr-CWS was added to the experiment group and PBS to the control. The growth and proliferation of HeLa cells were detected with MTT and flow cytometry technology. Inhibitive effect of HeLa transplanted tumor was investigated in Scid mice. RESULTS: The growth of HeLa cells in the experimental group was apparently decreased compared with that of the control. The results of flow cytometry demonstrated that more HeLa cells were transferred into quiescent phase in the experimental group than that in the control. While less in the proliferative phase, both of the volume and weight of HeLa transplanted tumor with drug-added group were less than those of control group. CONCLUSION: The Nocardia rubra cell wall skeleton is a potiental growth inhibitor and inducer of apoptosis of cervical cancer cells in vitro and may provide a new way in prevention or supplementary management of anti-human papilloma virus.
