Despite advances in chemotherapeutic drugs used against cervical cancer, available chemotherapy treatments adversely affect the patient's quality of life. For this reason, new molecules from natural sources with antitumor potential and few side effects are required. In previous research, , a phospholipase A type-Asp49 from snake venom, has shown selective attack against the HeLa and Ca Ski cervical cancer cell lines. This work suggests that the cytotoxic effect generated by on HeLa cells is triggered without affecting the integrity of the cytoplasmic membrane or depolarizing the mitochondrial membranes. The results allow us to establish that cell death in HeLa is related to the junction blockage between αβ integrins and fibronectin of the extracellular matrix. reduces the cells' ability of adhesion and affects survival and proliferation pathways mediated by intracellular communication with the external environment. Our findings confirmed as a potential prototype for developing a selective chemotherapeutic drug against cervical cancer.
尽管针对宫颈癌的化疗药物取得了进展,但现有的化疗治疗方法会对患者的生活质量产生不良影响。因此,需要具有抗肿瘤潜力且副作用较少的天然来源的新分子。在之前的研究中,一种来自蛇毒的磷脂酶 A2-Asp49,已显示出对 HeLa 和 Ca Ski 宫颈癌细胞系的选择性攻击。这项工作表明,对 HeLa 细胞产生的细胞毒性作用是在不影响细胞质膜完整性或线粒体膜去极化的情况下触发的。结果表明,HeLa 细胞的死亡与细胞外基质中 αβ 整合素与纤连蛋白之间的连接阻断有关。降低了细胞的黏附能力,并影响了细胞内与外部环境进行通讯的生存和增殖途径。我们的研究结果证实 是一种针对宫颈癌的选择性化疗药物的潜在原型。
