Abstract:
Objective To investigate the effect of LI-cadherin- SiRNA protein on the growth and metastatic potentials of transplanted human hepatocellular carcinoma cell lines (Hep3B) in nude mice.Methods We transfected LI-cadherin- SiRNA to Hep3B cells,Hep3B cell suspension (transfected or control ) was injected subcapsullaryly into the spleen of nude mice,hepatic metastasis was observed by naked eye and immunohistochemistry.In addition,Western-blot was used to detect the level of LI-cadherin in different metastatic site.Results (1) Hep3B was green after successful transfect interference vector under fluorescence inverted microscope,in this study,the transfect rate was 80%.(2) Hep3B liver metastasis model in nude mice was established.The metastasis rates in the empty plasmid carrying group,the control group and the SiRNA transfect group were 50%,60% and 80%,respectively.The number of metastasis caner nodules in the SiRNA transfect group was 26,significantly higher than other two groups.(3) The level of protein expression for LI-cadherin in the SiRNA transfect group is significantly lower than the control group and the empty plasmid carrying group.Conclusions LI-cadherin is crucial and important for the adhension capability of HCC in its migration.SiRNA transfected LI-cadherin increases the metastasis in a nude mouse model inoculated with human hepatocellular carcinoma cell lines.
