To evaluate the anticancer activity of methanolic extract of Illicium verum against triple-negative breast cancer MDA-MB-231 cell line.
A cell culture experimental study was carried out at Pharmacology department of Bahria University Medical and Dental College (January to June 2021) in collaboration with Aga Khan University, Karachi, Pakistan. Cell viability and proliferation assays were used to quantify dead and alive cells by utilizing a tetrazolium assay and an enzyme immunosorbent plate reader was used to calculate their absorbance. For the apoptosis initiation assay, these cells were dyed with a fluorescent stain and observed for fluorescence and apoptosis. During cell viability testing, various methanolic extract doses (0.125, 0.25, 0.5, 1, 3, 6, 12, and 25µg/ml) were employed to treat MDA-MB-231 cells, while the IC dose of 2.8µg/ml was used for both the cell proliferation and apoptosis initiation assays.
In the cell viability assay, all methanolic extract doses exhibited a substantial decrease in the viability of MDA-MB-231 cells (less than 0.01 p-value). In cell proliferation assay and apoptosis initiation, the IC dose of 2.8µg/ml of methanolic extract also exhibited a substantial decrease in cell division (less than 0.01 p-value) and the initiation of apoptosis in MDA-MB-231 cells.
methanolic extract have strong anticancer activity against triple-negative breast cancer MDA-MB-231 cell line through cytotoxicity, proliferation reduction, and apoptosis initiation mechanisms.
评估八角茴香甲醇提取物对三阴性乳腺癌MDA-MB-231细胞系的抗癌活性。
2021年1月至6月,在巴哈里亚大学医学院药理学系与巴基斯坦卡拉奇阿迦汗大学合作开展了一项细胞培养实验研究。采用细胞活力和增殖试验,利用四氮唑试验对死细胞和活细胞进行定量,并使用酶标仪计算其吸光度。对于凋亡起始试验,用荧光染料对这些细胞进行染色,并观察荧光和凋亡情况。在细胞活力测试中,使用不同剂量的甲醇提取物(0.125、0.25、0.5、1、3、6、12和25µg/ml)处理MDA-MB-231细胞,而在细胞增殖和凋亡起始试验中均使用2.8µg/ml的半数抑制浓度(IC)剂量。
在细胞活力试验中,所有甲醇提取物剂量均使MDA-MB-231细胞的活力显著降低(p值小于0.01)。在细胞增殖试验和凋亡起始试验中,2.8µg/ml的甲醇提取物半数抑制浓度剂量也使MDA-MB-231细胞的细胞分裂显著减少(p值小于0.01)并引发凋亡。
甲醇提取物通过细胞毒性、增殖减少和凋亡起始机制对三阴性乳腺癌MDA-MB-231细胞系具有强大的抗癌活性。
