Abstract | INTRODUCTION: METHODS: Lec-Doxosome was prepared by a post-insertion method based on the insertion of rBC2LCN lectin into the liposomal surface via a lipid linker. The in vitro cellular binding, uptake, and cytotoxicity of Lec-Doxosome were compared with the corresponding parameters in the unmodified liposomes by applying to human pancreatic cancer cell line (Capan-1) with affinity for rBC2LCN lectin. For the in vivo assay, Lec-Doxosome was intravenously injected once per week for a total of 3 weeks into mice bearing subcutaneous tumors. RESULTS: The in vitro application of Lec-Doxosome resulted in a 1.2- to 1.6-fold higher intracellular doxorubicin accumulation and a 1.5-fold stronger cytotoxicity compared with the respective rates of accumulation and cytotoxicity in the unmodified liposomes. In vivo, Lec-Doxosome reduced the mean tumor weight (368 mg) compared with that in mice treated with unmodified liposomes (456 mg), without causing any additional adverse events. CONCLUSION: It was demonstrated from the results obtained herein that rBC2LCN lectin is a potent modifier, as a means for boosting the efficiency of nanoparticles in the targeting of cancer cell surface glycans.
