The current study investigates the anticancer activity of protein derived from yeast against breast cancer. Yeast-derived proteins illustrate potential as an anticancer agent through mechanisms, such as immune system stimulation via beta-glucans, cytotoxic effects, and modulation of gut microbiota by probiotic strains. The antioxidant activity of yeast-derived proteins can aid in anticancer activity by neutralizing free radicals, thereby reducing oxidative stress and preventing damage to cellular DNA. Employing a comprehensive methodology encompassing yeast isolation, antioxidant screening, molecular characterization, bioactive protein purification, and MTT assay, the research provides crucial insights into the anticancer attributes of the protein extracted from the yeast. The findings reveal significant antioxidant activity that reduces reactive oxygen species (ROS) levels, which are implicated in cancer development. The MTT assay on MCF-7 breast cancer cell lines, characterized by estrogen receptor and progesterone receptor positivity and HER-2 negativity, determined an IC value of 54.89 µg/ml, indicating a dose-dependent decrease in cytotoxic effects. These results suggest that the protein derived from Trichosporon asahii VITSTB1 exhibits promising anti-breast cancer properties. Further research is necessary to elucidate the underlying mechanisms, assess efficacy and safety profiles, explore synergies with existing therapies, and conduct animal model studies. Advancing this line of inquiry will significantly contribute to biomedical research and industrial innovation.
本研究探讨了源于酵母的蛋白质对乳腺癌的抗癌活性。酵母衍生蛋白通过β-葡聚糖刺激免疫系统、细胞毒性作用以及通过益生菌菌株调节肠道微生物群等机制显示出作为抗癌剂的潜力。酵母衍生蛋白的抗氧化活性可以通过中和自由基来辅助抗癌活性,从而减少氧化应激并防止细胞 DNA 损伤。本研究采用包括酵母分离、抗氧化筛选、分子特征分析、生物活性蛋白纯化和 MTT 测定在内的综合方法,深入研究了从酵母中提取的蛋白质的抗癌特性。研究结果揭示了其具有显著的抗氧化活性,可降低与癌症发展相关的活性氧 (ROS) 水平。对 MCF-7 乳腺癌细胞系(雌激素受体和孕激素受体阳性,HER-2 阴性)进行的 MTT 测定确定 IC 值为 54.89µg/ml,表明细胞毒性作用呈剂量依赖性降低。这些结果表明,源于 Asahii Trichosporon VITSTB1 的蛋白表现出有前景的抗乳腺癌特性。需要进一步研究以阐明潜在机制、评估疗效和安全性概况、探索与现有疗法的协同作用以及进行动物模型研究。推进这一研究方向将为生物医学研究和工业创新做出重大贡献。
