Abstract

Non-small cell lung cancer (NSCLC) is a common malignancy with high mortality and poor prognosis. Levobupivacaine is a widely used local anesthetic and presents potential anti-tumor activity. Nevertheless, the function of levobupivacaine in the NSCLC development remains elusive. Here, we tried to investigate the impact of levobupivacaine on the NSCLC progression and the underlying mechanism. Significantly, we revealed that levobupivacaine could inhibit the proliferation and induce the apoptosis of NSCLC cells. Levobupivacaine was able to attenuate the invasion and migration in the cells. Meanwhile, the treatment of levobupivacaine enhanced the erastin-induced inhibition of cell growth of NSCLC cells. The treatment of levobupivacaine remarkably increased the levels of ROS, iron, and Fe2+ in NSCLC cells. Mechanically, levobupivacaine up-regulated the expression of p53 and induced ferroptosis by regulating p53 in NSCLC cells. Moreover, tumorigenicity analysis in nude mice showed that the treatment of levobupivacaine significantly repressed the tumor growth of NSCLC cells . In summary, we concluded that the local anesthetic levobupivacaine inhibits the progression and induces ferroptosis of NSCLC by up-regulating p53. Our finding provides new insights into the mechanism by which levobupivacaine attenuates the development of NSCLC. Levobupivacaine may serve as a potential anti-tumor candidate for the therapeutic strategy of NSCLC.

摘要

非小细胞肺癌(NSCLC)是一种常见的恶性肿瘤,死亡率高且预后较差。左旋布比卡因是一种广泛使用的局部麻醉剂,具有潜在的抗肿瘤活性。然而,左旋布比卡因在NSCLC发展中的作用仍不清楚。在此,我们试图研究左旋布比卡因对NSCLC进展的影响及其潜在机制。值得注意的是,我们发现左旋布比卡因可以抑制NSCLC细胞的增殖并诱导其凋亡。左旋布比卡因能够减弱细胞的侵袭和迁移能力。同时,左旋布比卡因处理增强了埃拉斯汀对NSCLC细胞生长的抑制作用。左旋布比卡因处理显著增加了NSCLC细胞中活性氧(ROS)、铁和亚铁离子(Fe2+)的水平。机制上,左旋布比卡因上调p53的表达,并通过调节p53诱导NSCLC细胞发生铁死亡。此外,裸鼠成瘤性分析表明,左旋布比卡因处理显著抑制了NSCLC细胞的肿瘤生长。总之,我们得出结论,局部麻醉剂左旋布比卡因通过上调p53抑制NSCLC的进展并诱导铁死亡。我们的发现为左旋布比卡因减弱NSCLC发展的机制提供了新的见解。左旋布比卡因可能成为NSCLC治疗策略中的一种潜在抗肿瘤候选药物。
