In this study, resveratrol-loaded solid lipid nanoparticles (Res-SLNs) were successfully designed to treat MDA-MB-231 cells. The Res-SLNs were prepared using emulsification and low-temperature solidification method. The Res-SLNs were spherical, with small size, negative charge, and narrow size distribution. Compared with free resveratrol, the Res-SLNs displayed a superior ability in inhibiting the proliferation of MDA-MB-231 cells. In addition, Res-SLNs exhibited much stronger inhibitory effects on the invasion and migration of MDA-MB-231 cells. Western blot analysis revealed that Res-SLNs could promote the ratio of Bax/Bcl-2 but decreased the expression of cyclinD1 and c-Myc. These results indicate that the Res-SLN may have great potential for breast cancer treatment.
本研究设计了载白藜芦醇固体脂质纳米粒(Res-SLNs)用于治疗 MDA-MB-231 细胞。Res-SLNs 采用乳化低温固化法制备。Res-SLNs 呈球形,粒径小,带负电荷,粒径分布较窄。与游离白藜芦醇相比,Res-SLNs 表现出更强的抑制 MDA-MB-231 细胞增殖的能力。此外,Res-SLNs 对 MDA-MB-231 细胞的侵袭和迁移具有更强的抑制作用。Western blot 分析表明,Res-SLNs 可以促进 Bax/Bcl-2 比值,但降低 cyclinD1 和 c-Myc 的表达。这些结果表明,Res-SLN 可能具有治疗乳腺癌的巨大潜力。
