Anticancer Agents Med Chem. 2025 Jun 23. doi: 10.2174/0118715206396025250614030603.
Cancer is a group of diseases caused by uncontrollable cell growth. Herbal medicines, derived from plants, have been used for centuries across cultures for their therapeutic benefits, effectively treating conditions like cancer. This study represents the anticancer effects of fractions of some medicinal plant extracts along with their apoptotic studies and their induction through p53-mediated Bax and Bcl-2 mRNA expression in HepG2 and U87MG cells.
The fractionation of crude methanolic extracts was done using Column Chromatography and Thin Layer Chromatography. The fractions were analysed for cytotoxicity against both the cell lines by MTT assay. Cancer cells were treated with 2 most active fractions and their mechanism of apoptosis induction was assessed by Flow Cytometry studies and the mRNA expression levels of p53, Bax, and Bcl-2 were determined by Reverse Transcriptase PCR. The presence of phytoconstituents in the active fractions was analysed by GC-MS.
The active fractions revealed the apoptosis induction in both the cell lines and the RT-PCR studies suggested the mechanism of apoptosis induction through upregulation of p53 and Bax and downregulation of Bcl-2 mRNA. The GC-MS analysis of active fractions from Balanites aegyptiaca and Pterocarpus marsupium revealed the presence of phytochemicals such as 4-O-Methylmannose, Oleic acid, Erucic acid, etc. which might have contributed to the anti-proliferative and apoptotic effects of these fractions.
4-O-Methylmannose was the major component identified with the highest peak area of 59%. The fractions from all the 4 plant extracts demonstrated significant cytotoxic effects on the liver (HepG2) and brain (U87MG) cancer cell lines, with particular emphasis on the active fractions BA FII, PM FII, and PM FIII. Additionally, the mechanisms of apoptosis induction through the modulation of p53, Bax, and Bcl-2 pathways, along with the presence of bioactive compounds further support the anticancer efficacy of these plant extracts. Also, to the best of our knowledge, this is the first study on fractions of Balanites aegyptiaca and Pterocarpus marsupium against U87MG cells.
The results highlight the promising potential of plant-derived natural products as anticancer agents. These findings provide valuable insight into the potential of herbal medicines and encourage further exploration of plant-based therapies for cancer treatment.
癌症是一组由细胞生长失控引起的疾病。源自植物的草药,在不同文化中已被使用了数百年,因其治疗功效,能有效治疗如癌症等病症。本研究阐述了某些药用植物提取物的各组分的抗癌作用,以及它们在肝癌细胞系HepG2和人恶性胶质瘤细胞系U87MG中的凋亡研究,及其通过p53介导的Bax和Bcl-2 mRNA表达的诱导情况。
采用柱色谱法和薄层色谱法对粗甲醇提取物进行分离。通过MTT法分析各组分对两种细胞系的细胞毒性。用2种活性最强的组分处理癌细胞,通过流式细胞术研究评估其凋亡诱导机制,并用逆转录聚合酶链反应测定p53、Bax和Bcl-2的mRNA表达水平。通过气相色谱-质谱联用仪分析活性组分中植物成分的存在情况。
活性组分在两种细胞系中均显示出凋亡诱导作用,逆转录-聚合酶链反应研究表明其凋亡诱导机制是通过上调p53和Bax以及下调Bcl-2 mRNA实现的。对埃及盐肤木和印度紫檀活性组分的气相色谱-质谱联用仪分析显示存在4-O-甲基甘露糖、油酸、芥酸等植物化学物质,这些物质可能促成了这些组分的抗增殖和凋亡作用。
4-O-甲基甘露糖是鉴定出的主要成分,其峰面积最高,为59%。所有4种植物提取物的组分对肝癌(HepG2)和脑癌(U87MG)细胞系均显示出显著的细胞毒性,尤其强调活性组分BA FII、PM FII和PM FIII。此外,通过调节p53、Bax和Bcl-2途径诱导凋亡的机制,以及生物活性化合物的存在,进一步支持了这些植物提取物的抗癌功效。而且,据我们所知,这是首次关于埃及盐肤木和印度紫檀组分对U87MG细胞作用的研究。
结果突出了植物源天然产物作为抗癌剂的广阔前景。这些发现为草药的潜力提供了宝贵的见解,并鼓励进一步探索基于植物的癌症治疗方法。
