雷公藤红素对HepG2细胞迁移的影响(1)
摘要：目的 探索雷公藤红素对HepG2细胞迁移较佳抑制作用浓度及时间。方法 将HepG2细胞铺于6孔板并培养，待贴壁细胞密度达到70%～80%后，采用划痕法制造细胞迁移模型，分为二甲基亚砜组及雷公藤红素5、1、0.5、0.1、0.01 μmol/L组，于0、6、12、24 h观察细胞形态及细胞迁移情况，拍照记录，计算细胞迁移速度及细胞迁移抑制率。结果 雷公藤红素对HepG2细胞迁移具有抑制作用，且其对细胞迁移抑制作用在一定范围内呈浓度依赖性，浓度越高其抑制细胞迁移的作用越明显。同一浓度不同作用时间高浓度雷公藤对HepG2细胞迁移的抑制作用差异有统计学意义(P<0.05)；同一时间不同浓度雷公藤红素对HepG2细胞迁移的抑制作用差异有统计学意义(P<0.05)；雷公藤红素高浓度组可使细胞形态发生改变。结论 高浓度雷公藤红素能使HepG2细胞形态发生改变并凋亡；雷公藤红素抑制了HepG2细胞迁移，且该抑制作用与浓度、时间相关，终浓度为5 μmol/L作用于HepG2细胞6 h时，其对HepG2细胞迁移抑制作用最明显。

Abstract：Objectives To explore a better inhibitory effect of concentration and time of Celastrol on migration of HepG2 cells. Methods HepG2 cells were planted and cultured in 6-well plates. When the adherent cell density reached 70%-80%， cell migration was manufactured by scratch experiment model. Then， cell morphology and cell migration were observed under microscope with different concentrations of Celastrol 5， 1， 0.5， 0.1， 0.01 μmol/L and DMSO at 0， 6， 12， 24 h. They were pictured and rates of cell migration and inhibition ratios of all groups were calculated. Results Celastrol inhibited HepG2 cell migration， and its inhibitory effect on the migration velocity was concentration-dependent in a certain range. The higher the concentration of Celastrol， the stronger effect is. Celastrol of the same concentration at different times had different inhibitory effect on cell migrationof HepG2 cells (P<0.05). Celastrol of different concentrations at the same time had different inhibitory effects on cell migration of HepG2 cells (P<0.05)；Celastrol of high concentration cause dsevere changes in the cell morphology. Conclusion Celastrol of high concentration causes changes in the cell morphology and cell apoptosis of HepG2 cells. Celastrol inhibits HepG2 cell migration， which is dependent on the concentration and action time. The inhibitory effect of Celastrol on HepG2 cell migration is most obvious under final concentration of 5 μmol/L at 6 h.
