This study is targeted at assessing the chemotherapy factor of the ethanol extract of Vernonia amygdalina Delile (VAD).
U87 glioblastoma cells were treated with extract and a fraction of Vernonia amygdalina Delile (VAD) was harvested from the herbarium. Cytotoxicity was evaluated to determine the IC50 through microscopic observation followed by an MTT assay. Subsequently, flow cytometry with a FACS type was employed to conduct cell cycle and apoptosis analyses. Annexin V/PI and PI markers were used to assess apoptosis and cell cycle progression.
The ethanol extract and ethyl acetate fraction of VAD showed promising effects as cancer chemotherapy in glioblastoma cells. The IC50 values for the extract and fraction were notably low, at 37.65 µg/ml and 10.12 µg/ml, respectively, for U87 cells. Analysis of apoptosis using FACS revealed a more pronounced apoptotic effect of the 15 µg/ml fraction of VAD on both early and late apoptosis compared to the 75 µg/ml extract of VAD. Although some differences in cell cycle properties were observed, there were no significant differences in cell cycle analysis between the extract and fraction.
These findings underscore the efficacy of VAD's ethanol extract and ethyl acetate fraction as chemotherapeutic agents against U87 cancer cells. The low IC50 values and significant induction of early apoptosis highlight the cytotoxic effects of these treatments on U87 cells.
本研究旨在评估 Vernonia amygdalina Delile(VAD)乙醇提取物的化疗因子。
用提取物处理 U87 神经胶质瘤细胞,并从标本中提取 Vernonia amygdalina Delile(VAD)的馏分。通过显微镜观察和 MTT 测定来评估细胞毒性,以确定 IC50。随后,采用流式细胞术进行细胞周期和凋亡分析。使用 Annexin V/PI 和 PI 标志物评估细胞凋亡和细胞周期进程。
VAD 的乙醇提取物和乙酸乙酯馏分在神经胶质瘤细胞中显示出有希望的癌症化疗作用。提取物和馏分的 IC50 值均较低,分别为 37.65 µg/ml 和 10.12 µg/ml,用于 U87 细胞。FACS 分析的凋亡结果表明,与 VAD 的 75 µg/ml 提取物相比,VAD 的 15 µg/ml 馏分对早晚期凋亡的促凋亡作用更为明显。虽然观察到细胞周期特性存在一些差异,但提取物和馏分之间的细胞周期分析没有显著差异。
这些发现强调了 VAD 的乙醇提取物和乙酸乙酯馏分作为针对 U87 癌细胞的化疗药物的功效。低 IC50 值和早期凋亡的显著诱导突出了这些治疗方法对 U87 细胞的细胞毒性作用。
