ABSTRACT
Objective:
To construct an adenovirus-mediated mouse endostatin vector (Ad-mEndo) and to observe its inhibitory effect on the pulmonary metastasis of osteosarcoma in nude mice, so as to discuss the relationship between ES expression and the pulmonary metastasis of osteosarcoma.Methods:
Recombinant adenovirus plasmid pDC315-mEndo was constructed and used to prepare recombinant Ad-mEndo. Osteosarcoma MG-63 cells were subcutaneously injected into the right fore limbs to establish nude mouse model of osteosarcoma; and the models were randomly divided into 3 groups Ad-mEndo group, Ad-EGFP group and PBS group; animals receiving no transplantation served as blank control. The corresponding agents were injected (20 ?l per time) for a consecutive of 5 times on a weekly basis. The tumor volumes, histopathological characteristics were observed; ELISA was employed to examine the serum ES level. Animals were sacrificed 7 weeks later and the pulmonary metastasis was observed.Results:
Sixteen days later,the tumor volume was (1.53?0.05)cm3 in Ad-EGFP group, (1.56?0.07)cm3 in the PBS group, and (0.91?0.03)cm3 in the Ad-mEndo group, with the tumor inhibitory rate being 40.7% in the last group. The serum ES level in the Ad-mEndo group was significantly higher than that of the other groups (P
