No obvious changes in cell growth were observed in vitro, compared with the cell line NuTu-19. Tumor growth rate and tumor size were lower in the syngeneic rats Fischer 344, who were injected by IL-12, B7-1 or IL-12/B7-1 gene modified tumor cells, compared with those in the control group.

在体外培养条件下，与野生型NuTu-19相比，各种基因修饰的肿瘤细胞的形态和生长速度无明显改变，在动物体内的致瘤性有不同程度的下降，生长速度有所减慢。

METHODS The inhibitory effect of nobiletin on proliferation of SMMC-7721 cells was assessed by MTT analysis and growth curve assay. Morphological changes under microscope were observed by Giemsa staining. Hepatic cancer H22 model in mice was performed through subcutaneous inoculation of Right-Sidedness Axilla of KM mice. Different dosages of nobiletin 125, 250, 500mgkg^(-1 were injected by intragastric gavage everyday.
