In this study, we evaluated the independent anticancer properties of a novel heat-stable lysozyme derived from the thermophilic bacterium (BplzC) to identify potential alternative therapies to address the suboptimal outcomes of current cancer treatments. Using the String 10.5 database, an protein-protein interaction study predicted that BplzC was a strong functional partner of cytochrome c, indicating a potential role in cancer cell apoptosis. Further, the HDOCK server predicted that BplzC strongly bound to cell death receptors, such as cytokines FAS receptor, leading to activation of cytochrome c and subsequent apoptosis in the cancer cell line. In vitro assays demonstrated uniform apoptotic activity of BplzC against various cancer cell lines, while showing no apoptotic activity against normal non-cancer cell lines. And showing no apoptotic activity against normal non-cancer cell lines suggested a very specific mode of action and without any adverse side effects. Additionally, BplzC exhibited ROS scavenging activity and reducing ability comparable to ascorbic acid, and significantly accelerated HEK293 cell migration. Our findings suggest that BplzC has specific cytotoxic effects on cancer cells and may be a valuable natural source of antioxidants for future use in the nutritional and pharmaceutical sectors.
在本研究中,我们评估了一种源自嗜热细菌的新型热稳定溶菌酶(BplzC)的独立抗癌特性,以确定潜在的替代疗法,解决当前癌症治疗效果欠佳的问题。使用String 10.5数据库进行的蛋白质-蛋白质相互作用研究预测,BplzC是细胞色素c的强大功能伙伴,表明其在癌细胞凋亡中可能发挥作用。此外,HDOCK服务器预测BplzC与细胞死亡受体(如细胞因子FAS受体)强烈结合,导致癌细胞系中细胞色素c的激活及随后的凋亡。体外试验表明,BplzC对各种癌细胞系具有一致的凋亡活性,而对正常非癌细胞系无凋亡活性。对正常非癌细胞系无凋亡活性表明其作用模式非常特异且无任何不良副作用。此外,BplzC表现出与抗坏血酸相当的活性氧清除活性和还原能力,并显著加速HEK293细胞迁移。我们的研究结果表明,BplzC对癌细胞具有特异性细胞毒性作用,可能是未来营养和制药领域有价值的天然抗氧化剂来源。
