BACKGROUND/AIM: To evaluate the anti-cancer mechanism of N-Farnesyl-norcantharimide (NC15).
The viability of NC15-treated human leukemic Jurkat T (JKT) cells was assessed using the Kit-8 cell counting method. Flow cytometry analysis, human apoptosis antibody array assay, and whole genome sequencing were adopted to investigate the mechanism underlying the anti-cancer activity of NC15 in JKT cells.
The growth inhibition rates of NC15 in JKT cells were about 80% and 95% after treatment with 8 μmol/l NC15 for 24 and 48 h, respectively. The percentages of NC15-treated JKT cells in the sub-G phase at 24 and 48 h were 22.0% and 34.3%, respectively, in contrast to the 1.5% in the control. Next-generation sequencing showed that many tumor suppressor genes (TSG) were up-regulated, while many genes associated with steroid biosynthesis, metabolic pathways, and fatty acid metabolism were down-regulated.
NC15 can reduce the cell viability and increase the percentage of JKT cells in the sub-G phase by up-regulating TSG and related genes, and down-regulating the genes for steroid biosynthesis, metabolic pathways and fatty acid metabolism, instead of through apoptosis.
背景/目的:评估 N-法呢基-去甲斑蝥素(NC15)的抗癌机制。
采用 Kit-8 细胞计数法评估 NC15 处理的人白血病 Jurkat T(JKT)细胞的活力。采用流式细胞术分析、人凋亡抗体阵列测定和全基因组测序来研究 NC15 在 JKT 细胞中抗癌活性的作用机制。
8 μmol/L NC15 处理 24 和 48 h 后,NC15 对 JKT 细胞的生长抑制率分别约为 80%和 95%。与对照组的 1.5%相比,24 和 48 h 时 NC15 处理的 JKT 细胞处于亚 G1 期的比例分别为 22.0%和 34.3%。下一代测序显示,许多肿瘤抑制基因(TSG)上调,而许多与类固醇生物合成、代谢途径和脂肪酸代谢相关的基因下调。
NC15 可通过上调 TSG 及相关基因,下调类固醇生物合成、代谢途径和脂肪酸代谢相关基因,而非通过凋亡来降低 JKT 细胞活力并增加亚 G1 期细胞的比例。
