Antitumor and antimetastatic effects of pemetrexed-loaded targeted nanoparticles in B16 bearing mice
2015
AbstractUsing nanoparticle delivery for anticancer therapy is a potential new drug modality. We developed a novel gelatinase–stimuli nanoparticle. In this study, we studied the antitumor and antimetastasis effect of pemetrexed-loaded targeted nanoparticles and evaluated the correlation between E-cadherin expression and lung metastasis in subcutaneous xenograft model. Compared with free pemetrexed, pemetrexed-loaded targeted nanoparticles exhibited the best antitumor and antimetastasis efficacy among the four therapeutic groups. The study also indicated that there was an inverse correlation between lung metastasis and E-cadherin expression. These results showed pemetrexed-loaded targeted nanoparticles may be a potent drug for tumor therapy and our preclinical data could provide new direction for clinical therapy of malignant melanoma.
