摘要: 研究核桃楸皮提取物(EMBJM)对人肝癌细胞SMMC-7721的增殖抑制作用及对细胞周期的影响。体外培养SMMC-7721细胞,并用不同浓度核桃楸皮甲醇提取物处理。通过MTT法研究EMBJM对SMMC-7721细胞增殖活性的影响;采用流式细胞仪分析EMBJM对SMMC-7721细胞周期的影响。EMBJM可以显著抑制SMMC-7721细胞生长,具有时间和计量依赖性。细胞周期实验表明EMBJM将SMMC-7721细胞阻滞在G2/M和S期,并具有剂量依赖性。EMBJM质量浓度为8和16mg/L时, G2/M期细胞所占百分比分别为13.89%±2.46%和14.35%±2.68%, 与空白对照组(8.34%±1.42%)比较,差异均有统计学意义(P<0.05);同等浓度范围内S期细胞所占百分比分别为39.87%±2.83%和44.81%±2.93%,与空白对照组(26.80%±1.76%)比较, 差异均有统计学意义(P<0.05)。桃楸皮甲醇提取物可以影响SMMC-7721细胞周期分布和有效抑制SMMC-7721细胞生长。

Abstract: To study effect of extracts from bark of Juglans mandshurica (EMBJM) on proliferation and cell cycle of SMMC-7721 cells, the SMMC-7721 cells in culture medium in vitro were given different concentrations of EMBJM. The inhibition rate of EMBJM on the SMMC-7721 cell was detected by MTT assay. The cell cycle analyzed was detected by flow cytometry (FCM). The EMBJM exhibited a significant inhibition on SMMC-7721 cells time-and dose-dependently. The cell cycle detection results suggested that EMBJM could arrest SMMC-7721 cells specifically in growth 2/mitosis(G2/M) and synthesis(S) phase cell cycle in a dose-dependent manner. Compared with control group (8.34%±1.42%; 26.80%±1.76%), the G2/M and S phase of SMMC-7721 cells exposed to EMBJM (13.89%±2.46%, 39.87%±2.83% (8 mg/L);(14.35%±2.68%, 44.81%±2.93% (16 mg/L)) were significantly increased (P<0.05, n=3). EMBJM can effectively inhibited proliferation in SMMC-7721 cells and effected cell cycle distribution.
