木犀草素对卵巢癌细胞株转移能力的影响

目的：研究木犀草素对卵巢癌细胞株HO-891 0PM的体外侵袭能力的影响，并探讨其可能的作用机制。方法：HO-8910P M细胞经木犀草素处理后用Boyden小室法检测其体外、侵袭和运动能力。并采用明胶酶 谱法检测HO-8910PM细胞分泌的明胶酶活性。RT-PCR检测TIMP-1、NM23基因mRNA的表达情况，蛋白印迹法检测ERK2的蛋白表达变化。结果：HO-8910PM细胞经木犀草 素处理后，体外侵袭、运动能力呈剂量依赖性下降。HO-8910PM细胞MMP-9的分泌下降。ERK2 蛋白表达明显降低，但TIMP-1、NM23基因mRNA的水平无明显变化。结论:木犀草素在体外剂量依赖性地抑制卵巢癌细胞HO-8910PM的转移能力，这可能与木犀草素 抑制MMP-9的分泌及下调ERK2表达有关。

Effect of luteolin on metastasis of ovarian carcinoma cell line

AIM: To explore the effect of luteolin on the metastasis of ovarian carcinoma HO-8910PM cells in vitro, and to elucidate its mechanisms. METHODS: The in vitro invasion and mobility of HO-8910PM were measured by Boyden chamber assay after exposure to luteolin for 6 h. Gelatinase activity was tested by gelatin zymography assay. The expression of tissue inhibitor of metalloproteinase-1 (TIMP-1), nm23 mRNA and that of ERK2 protein were tested by RT-PCR and Western blotting, respectively. RESULTS: Luteolin significantly inhibited in vitro invasiveness and mobility in HO-8910PM cells in a dose dependent manner as measured by Boyden chamber assay. Luteolin inhibited the MMP-9 secretion from HO-8910PM cells. Luteolin did not affect the mRNA expression of TIMP-1 and nm23. Luteolin also decreased ERK2 expression. CONCLUSION: Luteolin dose-dependently inhibited the metastasis of HO-8910PM cells in vitro. Inhibition of MMP-9 secretion and ERK2 expression may be involved in the anti-metastasic process of luteolin.
