摘要

Objective: To investigate anti-cancer activity of the novel survivin siRNA Folate Receptor (FR)-targeted Polyethylene-Glycol Liposomes (PEG) liposomes in K562-bearing nude mice. Methods: The leukemia cell line K562 xenograft model was established in balb/c nuu mice, and survivin siRNA FR-targeted PEG liposomes was administrated by intraperitoneal (i.p.). The same volume of liposomes was administrated as placebo control. The real time PCR and western blotting were used to examine the knocking down effect. The tumor weight and size in nude mice was measured to evaluate the inhibitory effect in vivo. Results: The expression ratio of survivin mRNA in siRNA group was 0.35 ± 0.1 (survivin/GAPDH) vs. 1.85 ± 0.65 in control group with significant difference (p < 0.05), as well as protein level by western blotting analysis (p < 0.05). The results also showed the novel survivin siRNA liposomes could inhibit the growth of K562 in xenograft model. Conclusion: This novel survivin siRNA FR-targeted PEG liposome delivery system may be a potential gene therapy for the treatment of leukemia.
