The effects of medical sodium hyaluronate gel on the tumor proliferation and metastasis / 药学实践杂志

ABSTRACT

Objective To investigate the effect of medical sodium hyaluronate gel (HA) on the growth and metastasis of abdominal and pelvic tumor cells in vitro and in nude mice. Methods Three tumor cells, Hela, CT26 and HCT116, were used to investigate the effects of different HA concentrations on the growth and migration of tumor cells in vitro by MTT assay and Transwell assay. An orthotopic transplantation model of colonic tumor in nude mice was established to investigate the effect on the proliferation of cell HCT116 by comparing the tumor volume and tumor mass 4 weeks after inoculation. The effects on the metastasis of cell CT26 were investigated by comparing the tumor metastasis rate and the number of metastatic lesions of lung and liver in nude mice among the different experimental groups 3 weeks after inoculation. Results HA did not promote the growth and metastasis of Hela, CT26 and HCT116 cells in vitro at different concentrations. Actually, HA exhibited a certain inhibitory activity at the concentration of 5 mg/ml. In the orthotopic transplantation model of colonic tumor-HCT116, HA did not promote the growth of cell HCT116. In the orthotopic transplantation model of colonic tumor-CT26, HA inhibited CT26 tumor metastasis. Conclusion Under the experimental conditions, HA did not promote the growth, migration or metastasis of abdominal and pelvic related tumor cells including Hela, CT26 and HCT116 in vitro and in vivo.
