摘要

本文研究了由90 mol% L-α-二myristoyl-磷脂酰胆碱(DMPC)和10 mol%聚氧乙烯(25)十二烷基醚(C12(EO)25)组成的混合脂质体(HLs)对人胶质瘤NP2细胞的抑制作用。水动力直径小于100 nm的ls持续4周。观察HLs对NP2细胞增殖的抑制作用。采用PI法和TUNEL法观察HL对NP2细胞凋亡的诱导作用。HLs通过线粒体途径引起NP2细胞凋亡。在hl处理的细胞中,AIF蛋白表达增加。荧光去极化法显示NP2细胞的细胞膜流动性增加。观察到NP2细胞膜中HL积累增强。

Inhibitory Effect of Hybrid Liposomes on the Growth of NP2 Glioma Cells
The inhibitory activity of hybrid liposomes (HLs), composed of 90 mol% L-α-dimyristoyl-phosphatidylcholine (DMPC) and 10 mol% polyoxyethylene (25) dodecyl ether (C12(EO)25), was investigated in human glioma NP2 cells. HLs with a hydrodynamic diameter below 100 nm persisted for 4 weeks. The inhibitory effect of HLs on the proliferation of NP2 cells was evaluated. Induction of apoptosis in NP2 cells treated with HL was measured through a PI assay and the TUNEL method. HLs caused apoptosis in NP2 cells through the mitochondrial pathway. An increase of AIF protein expression was observed in HL-treated cells. Cellular membrane fluidity of NP2 cells was also increased as revealed by the fluorescence depolarization method. Enhanced HL accumulation in the membrane of NP2 cells was observed.
