In this study, we found out that linalool, a small-molecule compound, could inhibit the growth of various human lymphocyte leukemia cell lines significantly. Meanwhile, it showed little toxicity to normal hematopoietic cells. To determine effects of linalool on the growth of a serious of human leukemia cell lines and normal hematopoietic cells and to explore its possible mechanisms, we employed various technologies, including MTT assay, Flow cytometry, Human Cancer PathwayFinder II Gene Array, Western Blot, RT-PCR and so on.

我们在筛选抗肿瘤小分子化合物时，发现天然小分子化合物芳樟醇能明显抑制多种人淋巴细胞白血病细胞增殖，而对正常人骨髓造血细胞及外周血细胞的增殖没有明显的影响，为此我们用MTT技术、流式细胞术、肿瘤相关信号通路分析技术以及Western blot、RT-PCR等手段和方法探讨了芳樟醇对不同类型白血病细胞系及相应正常造血细胞中的影响情况，及其诱导白血病细胞凋亡的可能分子机制。
