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.
