Description Bigelovin is a selective retinoid X receptor α agonist. Bigelovin suppresses tumor growth through inducing apoptosis and autophagy via the inhibition of mTOR pathway regulated by ROS generation.It is also known as a potent cytotoxic sesquiterpene lactone from Inula sp.
In vitro BigV 对人体肝癌细胞展现出了潜在的抗肿瘤活性,不论是体外还是体内实验均然。通过促进Caspase-3和聚(ADP-核糖)聚合酶1 (PARP-1)的裂解,BigV减少了细胞增殖和集落形成,并诱导了凋亡。该过程伴随着自噬的激活,如通过自噬体积聚增加、微管相关蛋白轻链3B-II (LC3B-II) 和Beclin-1的增强以及p62的减少所证明。另外,自噬阻断显著增强了BigV诱导的细胞死亡,指出自噬在肝癌细胞系中的细胞保护功能。此外,BigV处理通过失活蛋白激酶B (AKT)/哺乳动物雷帕霉素靶蛋白 (mTOR)/核糖体蛋白S6激酶 (p70S6K)的通路。值得注意的是,通过过度表达mTOR的磷酸化,BigV诱导的细胞死亡被抵消。有趣的是,通过预处理反应性氧物种(ROS)清除剂N-乙酰-L-半胱氨酸(NAC),消除了凋亡和自噬的诱导,表明ROS在调控BigV诱导的细胞死亡中扮演重要角色。
In vivo 活体内研究显示,BigV 通过激活凋亡和自噬机制,以剂量依赖的方式显著抑制了HepG2肝癌异种移植瘤的生长,同时具有低系统毒性。进一步揭示了BigV 对人类肝癌具有显著的抗肿瘤效果,因此可能作为预防肝癌的新型抗肿瘤药物。
