摘要: 目的 研究大黄素-8-O-β-D-葡萄糖苷(emodin-8-O-β-D-glucopyranoside,EG)对肿瘤细胞迁移以及荷瘤小鼠肿瘤转移的影响。方法 EG 0、50、100、200、400 mg·mL-1作用于小鼠乳腺癌4T1-Luc细胞、人结肠癌HCT116细胞、人神经母细胞瘤SH-SY5Y细胞24~72 h;MTT法检测其对细胞增殖活力的影响,划痕试验观察细胞迁移能力,Transwell小室试验检测细胞转移能力。将磷酸盐缓冲溶液(PBS)、EG低(2 mg·kg-1)、高(4 mg·kg-1)剂量作用于荷乳腺癌4T1-Luc原位移植瘤小鼠,给药13天,每2天通过小动物成像系统观察肿瘤转移情况。结果 体外细胞实验表明,EG呈浓度和时间依赖性地抑制肿瘤细胞迁移,呈浓度依赖性抑制肿瘤细胞转移;动物体内实验结果表明,EG对乳腺癌小鼠原位移植瘤转移具有抑制作用。结论 EG在体内外均表现出抑制肿瘤细胞迁移和转移的能力。

Abstract: Objective To investigate the effects of emodin-8-O-β-D-glucopyranoside (EG) on tumor cell migration in vitro and tumor metastasis of tumor-bearing mice in vivo. Methods Different kinds of cells (mouse breast cancer cell 4T1-Luc, human colorectal cancer cell HCT116 and human neuroblastoma cell SH-SY5Y) were treated with 0, 100, 200, 400 mg·mL-1 EG while cell proliferation, cell migration and metastasis ability were detected by MTT assay, wound healing and Transwell assay respectively. Then, orthotopic 4T1-Luc bearing mice were treated with phosphate-buffer saline (PBS) and EG at low (2 mg·kg-1) and high (4 mg·kg-1) doses for 13 days respectively. Tumor metastasis was observed by the animal imaging system every two days during the period. Results EG could inhibit tumor cell migration in a concentration- and time-dependent manner in these three kinds of cells. It also inhibited tumor cell metastasis in a concentration-dependent manner. In the animal study, EG could also inhibit tumor metastasis in 4T1-Luc bearing mice. Conclusion EG has the ability to inhibit tumor cell migration and metastasis both in vitro and in vivo.
