OBJECTIVE
To test the anti-cancer effect of mannan-modified targeted nanoliposome on mice.
METHODS
The 3beta[N-(N',N'-dimethylaminoethane) -carbamoyl] cholesterol (DC-chol) was synthesized by the chemical reaction of cholesteryl chloroformate and N, N-dimethylethylendiamine. The DC-chol was then mixed with dioleoylphosphatidylethanolamine (DOPE) and chol-AECM-mannan to produce the sonicated mannan-modified targeted nanoliposome. The size of the nanoliposome was measured by zetasizer. Nanoliposome or purified EGFR (as control) was injected to the C57 mice with implanted lung cancers intravenously. The growth of tumors was observed, followed by ELISA and Western tests of serum antibodies.
RESULTS
The liposome nanoparticle had a size of 132 nm. The experimental groups had significant higher levels of blood serum antibodies than the controls. The experimental groups also had less volumes of tumors than the controls (P<0.05).
CONCLUSIONS
The growth of tumor has been inhibited by mannan-modified targeted nanoliposome. The mannan-modified targeted nanoliposome has anti-cancer effect on mice.
