摘要:
[摘要]目的 探讨功效部位AMH-T对人Hela、HepG2和U251体外抗肿瘤作用,了解其剂量-反应和时间-效应关系,发现对AMH-T敏感的肿瘤细胞株.方法 采用体外抗肿瘤实验进行体外抗癌活性检测.实验设阴性对照组(DMSO)、阳性对照组(DDP,3 μM)、AMH-T的5个剂量组(2、4、8、16和32 μg/mL).采用MTT法检测药物处理24 h、48 h和72 h后的OD值,计算各组的增殖抑制率. 结果 AMH-T作用72 h后,在AMH-T为8 μg/mL时,显微镜下观察Hela细胞几乎死亡.AMH-T在剂量为2、4、8、16和32 μg/mL时,对人宫颈癌细胞株Hela的抑制率分别为-5.54%、2.93%、72.14%、74.41%和73.86%,其IC50为11.66 μg;对人肝癌细胞株HepG2的抑制率分别为3.87%、12.50%、54.07%、55.27%和51.86%,其IC50为22.90 μg;对人神经胶质瘤细胞株U251的抑制率分别为-5.47%、1.08%、54.83%、57.75%和71.78%,其IC50为16.85 μg.结论 AMH-T对Hela、HepG2和U251均具有显著性的体外抗肿瘤作用,存在明显的剂量-反应和时间-效应关系;Hela细胞株对AMH-T最为敏感.

Abstract:
[Abstract]Objective To investigate the in vitro anticancer effects of the bioactive fraction AMH-T on human cancer cell lines Hela,U251,HepG2 and the dose-effect and time-effect relationship. Methods MTT assay was used to evaluate the anticancer effect of AMH-T in vitro. The experiment set the negative group(DMSO), the positive group(DDP,3 μM), five dosage groups of AMH-T(2, 4, 8, 16, 32 μg/mL). The tumor inhibition rate in each group was tested by MTT assay on 24 h, 48 h and 72 h after treatment. Results After 72h treatment with 8 μg/ml of AMH-T,most Hela cells died under inverted microscope. The inhibitory ratios of AMH-T at 2, 4, 8, 16, 32 μg/mL on Hela cells were -5.54%, 2.93%, 72.14%, 74.41% and 73.86%; 3.87%, 12.50%, 54.07%, 55.27% and 51.86% on HepG2 cells, and -5.47%, 1.08%, 54.83%, 57.75% and 71.78% on U251 cells. The IC50 values against Hela, HepG2 and U251 were 11.66 μg, 22.90 μg,and 16.85 μg,respectively. Conclusions AMH-T has significant anticancer effects on Hela,HepG2 and U251 cells in a concentration and time dependent manner. Hela cell line is most sensitive to AMH-T among three cell lines.
