Lung cancer is the most prevalent oncological disease worldwide, with non-small-cell lung cancer accounting for approximately 85% of lung cancer cases. is a traditional Chinese herb that is widely used to treat rheumatism, pain, inflammation, tumors, and other diseases. In this study, we found that Triptonodiol extracted from inhibited the migration and invasion of non-small-cell lung cancer and inhibited cytoskeletal remodeling, which has not been previously reported. Triptonodiol significantly inhibited the motility activity of NSCLC at low toxic concentrations and suppressed the migration and invasion of NSCLC. These results can be confirmed by wound healing, cell trajectory tracking, and Transwell assays. We found that cytoskeletal remodeling was inhibited in Triptonodiol-treated NSCLC, as evidenced by the reduced aggregation of actin and altered pseudopod morphology. Additionally, this study found that Triptonodiol induced an increase in complete autophagic flux in NSCLC. This study suggests that Triptonodiol reduces the aggressive phenotype of NSCLC by inhibiting cytoskeletal remodeling and is a promising anti-tumor compound.
肺癌是全球最普遍的恶性肿瘤疾病,其中非小细胞肺癌约占肺癌病例的 85%。重楼是一种传统的中草药,广泛用于治疗风湿、疼痛、炎症、肿瘤等疾病。在这项研究中,我们发现从重楼中提取的三尖杉宁醇抑制了非小细胞肺癌的迁移和侵袭,并抑制了细胞骨架重塑,这在以前的报道中尚未发现。三尖杉宁醇在低毒性浓度下显著抑制 NSCLC 的运动活性,并抑制 NSCLC 的迁移和侵袭。这些结果可以通过划痕愈合、细胞轨迹追踪和 Transwell 分析来证实。我们发现细胞骨架重塑在三尖杉宁醇处理的 NSCLC 中受到抑制,这表现为肌动蛋白的聚集减少和伪足形态的改变。此外,这项研究还发现三尖杉宁醇诱导 NSCLC 中完整自噬通量的增加。这项研究表明,三尖杉宁醇通过抑制细胞骨架重塑降低了 NSCLC 的侵袭表型,是一种有前途的抗肿瘤化合物。
