摘要
目的:观察去甲二氢愈创木酸(NDGA)对人恶性胶质瘤细胞系SHG-44细胞增殖和分化的影响。方法:细胞培养、免疫组化、光镜和电镜观察及流式细胞仪检测。结果:①在200μmol/L浓度范围内,NDGA对SHG-44细胞有增殖抑制和诱导分化作用,且这种作用与浓度呈正相关;②在NDGA处理96h内,NDGA对SHG-44细胞的增殖抑制作用以处理后24h最明显;③NDGA处理后,SHG-44细胞增殖受阻于G1→S期。结论:NDGA对SHG-44细胞有明显的增殖抑制和诱导分化作用,且这种作用有周期特异性。
Objective: To investigate the effects of nordihydroguaiaretic acid (NDGA) on proliferation and differentiation of human malignant glioma cell line SHG 44. Methods: Cell culture, immunohistochemistry, flow cytometry, light and electron microscopy were employed in this study. Results: ①NDGA with a concentration within 200 μmol/L inhibited the proliferation of SHG 44 cells and this effect was positively correlated to the concentration. ②The most conspicuous inhibition of the proliferation was found at the 24 th h after treatment with 100 μmol/L NDGA for up to 96 h. ③Cell cycle revealed that the cell proliferation was blocked in the phase of G1 to S after treatment with NDGA. Conclusion: NDGA can inhibit proliferation and induce differentiation of human malignant glioma cells and this effect is cycle specific.
