Oxypeucedanin (OPD), a furocoumarin compound from Angelica dahurica (Umbelliferae), exhibits potential antiproliferative activities in human cancer cells. However, the underlying molecular mechanisms of OPD as an anticancer agent in human hepatocellular cancer cells have not been fully elucidated. Therefore, the present study investigated the antiproliferative effect of OPD in SK-Hep-1 human hepatoma cells. OPD effectively inhibited the growth of SK-Hep-1 cells. Flow cytometric analysis revealed that OPD was able to induce G2/M phase cell cycle arrest in cells. The G2/M phase cell cycle arrest by OPD was associated with the downregulation of the checkpoint proteins cyclin B1, cyclin E, cdc2, and cdc25c, and the up-regulation of p-chk1 (Ser345) expression. The growth-inhibitory activity of OPD against hepatoma cells was found to be p53-dependent. The p53-expressing cells (SK-Hep-1 and HepG2) were sensitive, but p53-null cells (Hep3B) were insensitive to the antiproliferative activity of OPD. OPD also activated the expression of p53, and thus leading to the induction of MDM2 and p21, which indicates that the antiproliferative activity of OPD is in part correlated with the modulation of p53 in cancer cells. In addition, the combination of OPD with gemcitabine showed synergistic growth-inhibitory activity in SK-Hep-1 cells. These findings suggest that the anti-proliferative activity of OPD may be highly associated with the induction of G2/M phase cell cycle arrest and upregulation of the p53/MDM2/p21 axis in SK-HEP-1 hepatoma cells.

Oxypeucedanin 通过诱导 G2/M 期细胞周期停滞和 p53 依赖性 MDM2/p21 在人肝癌细胞中表达的抗增殖活性

Oxypeucedanin (OPD) 是一种来自白芷(伞形科)的呋喃香豆素化合物,在人类癌细胞中具有潜在的抗增殖活性。然而,OPD作为人类肝细胞癌细胞抗癌剂的潜在分子机制尚未完全阐明。因此,本研究调查了 OPD 在 SK-Hep-1 人肝癌细胞中的抗增殖作用。OPD有效抑制SK-Hep-1细胞的生长。流式细胞术分析表明,OPD 能够在细胞中诱导 G2/M 期细胞周期停滞。OPD 引起的 G2/M 期细胞周期停滞与检查点蛋白细胞周期蛋白 B1、细胞周期蛋白 E、cdc2 和 cdc25c 的下调以及 p-chk1 (Ser345) 表达的上调有关。发现 OPD 对肝癌细胞的生长抑制活性是 p53 依赖性的。p53 表达细胞(SK-Hep-1 和 HepG2)是敏感的,但 p53 无效细胞(Hep3B)对 OPD 的抗增殖活性不敏感。OPD 还激活 p53 的表达,从而导致 MDM2 和 p21 的诱导,这表明 OPD 的抗增殖活性部分与癌细胞中 p53 的调节相关。此外,OPD 与吉西他滨的组合在 SK-Hep-1 细胞中显示出协同的生长抑制活性。这些发现表明,OPD 的抗增殖活性可能与诱导 G2/M 期细胞周期停滞和 SK-HEP-1 肝癌细胞中 p53/MDM2/p21 轴的上调高度相关。OPD 还激活 p53 的表达,从而导致 MDM2 和 p21 的诱导,这表明 OPD 的抗增殖活性部分与癌细胞中 p53 的调节相关。此外,OPD 与吉西他滨的组合在 SK-Hep-1 细胞中显示出协同的生长抑制活性。这些发现表明,OPD 的抗增殖活性可能与诱导 G2/M 期细胞周期停滞和 SK-HEP-1 肝癌细胞中 p53/MDM2/p21 轴的上调高度相关。OPD 还激活 p53 的表达,从而导致 MDM2 和 p21 的诱导,这表明 OPD 的抗增殖活性部分与癌细胞中 p53 的调节相关。此外,OPD 与吉西他滨的组合在 SK-Hep-1 细胞中显示出协同的生长抑制活性。这些发现表明,OPD 的抗增殖活性可能与诱导 G2/M 期细胞周期停滞和 SK-HEP-1 肝癌细胞中 p53/MDM2/p21 轴的上调高度相关。OPD 与吉西他滨的组合在 SK-Hep-1 细胞中显示出协同的生长抑制活性。这些发现表明,OPD 的抗增殖活性可能与诱导 G2/M 期细胞周期停滞和 SK-HEP-1 肝癌细胞中 p53/MDM2/p21 轴的上调高度相关。OPD 与吉西他滨的组合在 SK-Hep-1 细胞中显示出协同的生长抑制活性。这些发现表明,OPD 的抗增殖活性可能与诱导 G2/M 期细胞周期停滞和 SK-HEP-1 肝癌细胞中 p53/MDM2/p21 轴的上调高度相关。
