ABSTRACT
Objective To synthesize H.pylori bacterial ghosts (BG) and loaded with adriamycin.The cytotoxic effects in gastric cancer cell line were also observed.MethodsThe lysis plasmid was introduced into H.pylori by bacterial conjugation. H.pylori BG were produced by inducing H.pylori lysis at 42 ℃.After suspension and centrifuge, H.pylori BG were loaded with adriamycin.The adriamycin loading quantity was measured with spectrophotometry.The cytotoxic effects of H.pylori BG-adriamycin in gastric cancer cell line SGC7901 were evaluated with MTT assay.ResultsH.pylori BG were successfully synthesized and loaded with adriamycin.The loading quantity of adriamycin was 70.4 μg/mg.H.pylori BG were seen to be adsorbed and internalized by gastric cancer cells under confocal microscope, which distributed on the surface or cytoplasmic of SGC7901 cell line. Carried Adriamycin was delivered into gastric cancer cell line and mainly accumulated in the nucleus.IC50 of SGC7901 to H.pylori BG-adriamycin was 0.32 ± 0.15 by MTT assay, which was significantly lower than that to free adriamycin (0.44 ±0.15, P<0.05).Conclusions The proliferation of gastric cancer cells were effectively inhibited by H.pylori BG-adriamycin.H.pylori BG are expected to be ideal carrier for anti-gastric cancer medicine.
