Gliomas, including glioblastoma multiforme and astrocytoma, are common brain cancers in adults. Propolis is a natural product containing many active ingredients. The aim of this study was to compare the chemical composition, total phenolic content and concentration of toxic elements as well as the anticancer potential of Polish (PPE) and New Zealand (Manuka-MPE) propolis extracts on diffuse astrocytoma derived from patient (DASC) and glioblastoma (T98G, LN-18) cell lines. The antioxidants such as flavonoids and chalcones (pinocembrin, pinobanksin, pinobanksin 3-acetate and chrysin) were the main components in both types of propolis. The content of arsenic (As) and lead (Pb) in MPE was higher than PPE. The anti-proliferative study showed strong activity of PPE and MPE propolis on DASC, T98G, and LN-18 cells by apoptosis induction, cell cycle arrest and attenuated migration. These findings suggest that despite their different geographic origins, Polish and New Zealand propolis are sources of antioxidant compounds and show similar activity and a promising anti-glioma potential in in vitro study. However, further in vivo studies are required in order to assess therapeutic potential of propolis.
胶质瘤,包括多形性胶质母细胞瘤和星形细胞瘤,是成人常见的脑癌。蜂胶是一种含有多种活性成分的天然产物。本研究的目的是比较波兰蜂胶(PPE)和新西兰麦卢卡蜂胶(Manuka-MPE)提取物的化学成分、总酚含量和有毒元素浓度,以及它们对源自患者的弥漫性星形细胞瘤(DASC)和胶质母细胞瘤(T98G、LN-18)细胞系的抗癌潜力。黄酮类化合物和查耳酮(松属素、白杨素、白杨素3-乙酸酯和 Chrysin)等抗氧化剂是两种蜂胶的主要成分。MPE中砷(As)和铅(Pb)的含量高于PPE。抗增殖研究表明,PPE和MPE蜂胶通过诱导凋亡、细胞周期阻滞和减弱迁移,对DASC、T98G和LN-18细胞具有很强的活性。这些发现表明,尽管波兰蜂胶和新西兰蜂胶的地理来源不同,但它们都是抗氧化化合物的来源,并且在体外研究中显示出相似的活性和有前景的抗胶质瘤潜力。然而,需要进一步的体内研究来评估蜂胶的治疗潜力。
