Doxorubicin (DOX) is an effective anticancer drug. But its clinical application is limited, because DOX induces apoptosis in cardiomyocytes and it leads to permanent degenerative cardiomyopathy and heart failure. Recent trainings showed that exhibit pharmacological actions such as potent antioxidant. So, in this study we explored the protective effect of extract on doxorubicin-induced cytotoxicity in H9c2 cells. Cell viability was quantified by MTT assay. Apoptotic cells were determined using PI staining of DNA fragmentation by flowcytometry (sub-G1 peak). Cells were cultured with 5 μM DOX for 24 h to create the cell damage. H9c2 cells were pretreated with different concentrations (7.81-500 μg/mL) of extract (HSE) for 2 h before DOX treatment in all trials. Pretreatment with HSE increased cell viability at concentration of 31.25-500 μg/mL. Compared to control cells, apoptosis was induced in DOX treated cells after 24 h, (𝑃< 0.001). Pretreatment with HSE significantly decreased cell apoptosis after 24 hr at concentration of 31.25-250 μg/mL. Our results show that could exert the cardioprotective effects on DOX-induced toxicity partly by antiapoptotic activity.
阿霉素(DOX)是一种有效的抗癌药物。但其临床应用受到限制,因为DOX会诱导心肌细胞凋亡,并导致永久性退行性心肌病和心力衰竭。最近的研究表明,[提取物名称]具有强大的抗氧化剂等药理作用。因此,在本研究中,我们探讨了[提取物名称]提取物对阿霉素诱导的H9c2细胞毒性的保护作用。通过MTT法对细胞活力进行定量分析。使用流式细胞术(亚G1峰)对DNA片段进行PI染色来测定凋亡细胞。在所有试验中,将细胞与5μM DOX培养24小时以造成细胞损伤。在DOX处理前2小时,用不同浓度(7.81 - 500μg/mL)的[提取物名称]提取物(HSE)对H9c2细胞进行预处理。在31.25 - 500μg/mL浓度下,HSE预处理可提高细胞活力。与对照细胞相比,DOX处理24小时后的细胞诱导了凋亡(P < 0.001)。在31.25 - 250μg/mL浓度下,HSE预处理在24小时后显著降低了细胞凋亡。我们的结果表明,[提取物名称]可以部分通过抗凋亡活性对DOX诱导的毒性发挥心脏保护作用。
