Abstract

Searching for new sources of safe nutraceuticals antitumor drugs is an important issue. Consequentially, this study designed to assess the antitumor activity of extract in the treatment of hepatocellular carcinoma HepG2 cell line. Aerial parts of plants were collected, used for phytochemical analysis, and assessed for anticancer activity. The antitumor activity was evaluated through studying the cell viability and apoptotic pathway. The gas chromatography-mass spectrometry phytochemical analysis revealed that is a promising new source of several known antioxidant and antitumor compounds which could participate in drug development and exploration of alternative strategies to the harmful synthetic antitumor drugs. stifled HepG2 cell viability in a concentration-dependent manner. Meanwhile, tempted substantial apoptosis in HepG2 cells and enhanced the expression of miR-34a. However, the mRNA expression level of antiapoptotic B-cell lymphoma-2 was markedly decreased by treatment. Moreover, increased the protein expression of proapoptotic p53 and caspase 3/9 with reducing B-cell lymphoma-2 protein expression level. Thus, induced apoptosis in the HepG2 cells by overexpression of miR-34a which regulates p53/B-cell lymphoma-2/caspases signaling pathway. These findings were well appreciated with morphological studies of cells treated with In conclusion, could be a probable candidate agent for the initiation of cell apoptosis in HepG2 and thereby can serve as promising therapeutic agent for treatment of hepatocellular carcinoma which should attract further studies.

摘要

寻找安全的营养保健品抗肿瘤药物的新来源是一个重要问题。因此,本研究旨在评估提取物对肝癌HepG2细胞系的抗肿瘤活性。采集植物地上部分用于植物化学分析,并评估其抗癌活性。通过研究细胞活力和凋亡途径来评估抗肿瘤活性。气相色谱-质谱联用的植物化学分析表明,该植物是几种已知抗氧化剂和抗肿瘤化合物的有前景的新来源,这些化合物可参与药物开发以及探索替代有害合成抗肿瘤药物的策略。该植物提取物以浓度依赖的方式抑制HepG2细胞活力。同时,该提取物诱导HepG2细胞大量凋亡并增强miR-34a的表达。然而,该提取物处理后抗凋亡蛋白B细胞淋巴瘤-2的mRNA表达水平显著降低。此外,该提取物增加了促凋亡蛋白p53和半胱天冬酶3/9的蛋白表达,同时降低了B细胞淋巴瘤-2蛋白表达水平。因此,该提取物通过上调miR-34a诱导HepG2细胞凋亡,miR-34a可调节p53/B细胞淋巴瘤-2/半胱天冬酶信号通路。这些发现与用该提取物处理的细胞的形态学研究结果相符。总之,该提取物可能是诱导HepG2细胞凋亡的候选药物,从而可作为治疗肝细胞癌的有前景的治疗药物,值得进一步研究。
