Abstract:
Objective · To prepare the liposomal pemetrexed and investigate its effects on MCF-7 breast cancer cells in vitro and nude mice bearing MCF-7 xenograft tumors. Methods · Liposomal pemetrexed was prepared by film dispersion method. Inhibition of MCF-7 breast cancer cell lines was evaluated by CCK-8 method, and anti-tumor effects were investigated on Balb/c nude mice bearing MCF-7 xenograft tumors. Results · Liposomal pemetrexed inhibited the growth of MCF-7 cells. When the concentrations of pemetrexed were 0.20, 0.40 and 10.00 μg/mL, the cell viability in experiment group (liposomal pemetrexed) was significantly lower than that in control group (pemetrexed of same concentration gradient), with P values of 0.013, 0.035 and 0.041, respectively. Compared with blank group (same volume of PBS), the volumes and weights of tumors of nude mice in experiment group(liposomal pemetrexed) and control group (same volume of pemetrexed) were significantly lower, and the volume and weight of tumor in experiment group were also significantly lower than those in control group (P=0.000). Conclusion · Compared to bulk drug of pemetrexed, liposomal pemetrexed can inhibit the growth of MCF-7 breast cancer cells and the Balb/c nude mice bearing MCF-7 xenograft tumors.
