Doxorubicin (Dox), an antineoplastic agent is used as a primary anticancerous drug against various types of cancers. However, its associated toxicity to the cardiovascular system is major. Literature has recorded the cases of mortality due to poor validation and lack of prediagnosis of Dox-induced cardiotoxicity. Therapeutic interventions using natural products having cardioprotective properties with low toxic outcomes hold therapeutic potential for future cardio-oncological therapies. (Black berry), a traditional Indian herbal plant, has been researched and found to exert cardioprotective, anti-inflammatory, and antioxidant activities, which have been credited due to the presence of polyphenols, flavonoids, and tannins.
In the current research, we investigated the cardioprotective potential of Syzygium cumini against Doxorubicin-induced cardiotoxicity (DIC) in H9C2 cardiomyocytes. Methanolic seed extract preparation of was performed using the Soxhlet apparatus. Cell viability and cell death assays were performed to determine the cardiotoxic doses of Doxorubicin. Furthermore, the cardioprotective potential of extract against DIC was studied. Morphological and nuclear alterations in H9C2 cells were studied by microscopic assays using Giemsa, Haematoxylin-Eosin stain, and PI. The intracellular stress level and ROS production were studied using DCFH-DA followed by mitochondrial integrity analysis using fluorescent microscopic methods.
In the results, we investigated that Dox exerted a dose and time-dependent cardiotoxicity on H9C2 cardiomyocytes. Moreover, we observed that morphological and nuclear alterations caused by doxorubicin in dose-dependent manner were prevented by supplementing with Syzygium cumini polyphenols and it attenuated the oxidative stress in H9C2 cardiomyocytes effectively.
Conclusively, possesses cardioprotective potential in H9C2 cardiomyocytes in dox-induced cardiotoxicity.
阿霉素(Dox)是一种抗肿瘤药物,用作治疗各类癌症的主要抗癌药物。然而,它对心血管系统的相关毒性很大。文献记载了因阿霉素诱导的心脏毒性验证不足和缺乏预诊断而导致死亡的病例。使用具有心脏保护特性且毒性低的天然产物进行治疗干预,对未来心脏肿瘤治疗具有治疗潜力。印度传统草药植物(黑刺李)已被研究发现具有心脏保护、抗炎和抗氧化活性,这归因于其含有多酚、黄酮类化合物和单宁。
在当前研究中,我们研究了蒲桃对阿霉素诱导的H9C2心肌细胞心脏毒性(DIC)的心脏保护潜力。使用索氏提取器制备蒲桃种子甲醇提取物。进行细胞活力和细胞死亡测定以确定阿霉素的心脏毒性剂量。此外,研究了蒲桃提取物对DIC的心脏保护潜力。通过使用吉姆萨、苏木精-伊红染色和PI的显微镜检测研究H9C2细胞的形态和核改变。使用DCFH-DA研究细胞内应激水平和ROS产生,随后使用荧光显微镜方法进行线粒体完整性分析。
在结果中,我们研究发现阿霉素对H9C2心肌细胞具有剂量和时间依赖性的心脏毒性。此外,我们观察到补充蒲桃多酚可预防阿霉素以剂量依赖性方式引起的形态和核改变,并且它有效减轻了H9C2心肌细胞中的氧化应激。
总之,蒲桃在阿霉素诱导的心脏毒性中对H9C2心肌细胞具有心脏保护潜力。
