Liriodenine has wide pharmacological functions in phytochemistry, pharmacology and antitumor activities. The anticancer effects of liriodenine on the cell growth and apoptosis of human breast cancer MCF-7 cells, and the underlying mechanisms, are yet to be elucidated. Therefore, the present study investigated the anticancer effects of liriodenine on the cell growth and apoptosis of human breast cancer MCF-7 cells. We used MTT assay to measure cell growth, and flow cytometer and DAPI staining was used to analyze cell apoptosis. Then, Western blot analysis was executed to measure B-cell lymphoma-2 protein (Bcl-2), cyclin D1, vascular endothelial growth factor (VEGF), and p53 protein expression. The effect of liriodenine induced significant apoptosis and suppression of cell growth of the MCF-7 cells. Furthermore, the potential mechanism underlying its antitumor effect on MCF-7 cells may result from activation of caspase-3 activity, Bcl-2, cyclin D1 and VEGF, and promotion of p53 protein expression in MCF-7 cells. Therefore, the present results indicated that the anticancer effects of liriodenine suppress cell growth and induce the apoptosis of human breast cancer MCF-7 cells through inhibition of Bcl-2, cyclin D1 and VEGF expression, and upregulation of p53 expression. Therefore, liriodenine may be a potential therapy for the treatment of human breast cancer.
莲叶桐碱在植物化学、药理学及抗肿瘤活性方面具有广泛的药理作用。莲叶桐碱对人乳腺癌MCF-7细胞的细胞生长和凋亡的抗癌作用及其潜在机制尚待阐明。因此,本研究探讨了莲叶桐碱对人乳腺癌MCF-7细胞的细胞生长和凋亡的抗癌作用。我们使用MTT法检测细胞生长,采用流式细胞仪和DAPI染色分析细胞凋亡。然后,进行蛋白质免疫印迹分析以检测B细胞淋巴瘤-2蛋白(Bcl-2)、细胞周期蛋白D1、血管内皮生长因子(VEGF)和p53蛋白的表达。莲叶桐碱的作用诱导了MCF-7细胞显著的凋亡并抑制了其细胞生长。此外,其对MCF-7细胞抗肿瘤作用的潜在机制可能是由于激活了半胱天冬酶-3活性、Bcl-2、细胞周期蛋白D1和VEGF,并促进了MCF-7细胞中p53蛋白的表达。因此,目前的结果表明,莲叶桐碱的抗癌作用通过抑制Bcl-2、细胞周期蛋白D1和VEGF的表达以及上调p53的表达来抑制细胞生长并诱导人乳腺癌MCF-7细胞凋亡。因此,莲叶桐碱可能是治疗人类乳腺癌的一种潜在疗法。
