Abstract
The anti-metastatic effects of cationic liposomes (CL) composed of 87 mol% dimyristoylphosphatidylcholine (DMPC), 8 mol% O,O′-ditetradecanoyl-N-(α–trimethylammonioacetyl) diethanolamine chloride (2C14ECl) and 5 mol% polyoxyethylene(21) dodecyl ether (C12(EO)21) was investigated for human pancreatic cancer (BxPC-3) cells. The inhibitory effect of CL on the migration of BxPC-3 cells was observed based on a wound scratch assay. CL suppressed pseudopodium formation of BxPC-3 cells. The anti-invasive effect of CL against BxPC-3 cells was observed via a Matrigel invasion assay. The anti-invasive effect of CL for BxPC-3 cells was found to occur through the inhibition of MMP2, MMP9, and MMP14. Overall, the results of this study revealed for the first time, the therapeutic effects and anti-metastasis activity of CL in xenograft mouse models for peritoneal metastasis of human pancreatic cancer.
