Benzyl isothiocyanate (BITC) has been shown to have inhibitory potential for human glioma U87MG cells; however, the effect and mechanism were not fully clear. In the present study, we found that BITC could inhibit U87MG cell proliferation, adhesion, invasion, and vasculogenic mimicry (VM) formation potential and induce oxidative stress, apoptosis, and cell cycle arrest. We also found that the expression of proliferation, invasion, VM oxidative stress, apoptosis, and cell cycle-related gene and the activity of tumor-related signaling pathways, including protein kinase C (PKC) ζ and Akt/nuclear factor-kappa B (NF-κB) pathways, were suppressed by BITC treatment. We also explored the anti-tumor potential of BITC in vivo, and we found that BITC also could regulate the expression of tumor-related gene and angiogenesis in nude mice model. Finally, we optimized the BITC construction targeting alkylglycerone phosphate synthase (AGPS) by computer-aided design, and the derivants also showed anti-tumor potential in vitro.
异硫氰酸苄酯(BITC)已被证明对人胶质瘤U87MG细胞具有抑制潜力;然而,其作用效果和机制尚不完全清楚。在本研究中,我们发现BITC可抑制U87MG细胞增殖、黏附、侵袭以及血管生成拟态(VM)形成潜力,并诱导氧化应激、细胞凋亡和细胞周期停滞。我们还发现,BITC处理可抑制增殖、侵袭、VM、氧化应激、细胞凋亡以及细胞周期相关基因的表达,以及包括蛋白激酶C(PKC)ζ和Akt/核因子-κB(NF-κB)通路在内的肿瘤相关信号通路的活性。我们还在体内探索了BITC的抗肿瘤潜力,发现在裸鼠模型中BITC也可调节肿瘤相关基因的表达和血管生成。最后,我们通过计算机辅助设计优化了靶向烷基甘油磷酸合酶(AGPS)的BITC结构,其衍生物在体外也显示出抗肿瘤潜力。
