Abstract

Scutellarin, an active component of flavonoid, displays a variety of physiological actions and has been applied for the treatment of diverse diseases including hypertension and cerebral infarction as well as cerebral thrombosis. In recent time, Scutellarin has been demonstrated to possess the anticancer activity. But the biological significance of Scutellarin in bladder cancer (BC) remains to be elucidated. In the current study, we explored the specific effect of Scutellarin on BC progression. We found that Scutellarin inhibited hypoxia-induced BC cell migration and invasion in vitro as well as suppressed hypoxia-induced BC metastasis in vivo. Moreover, Scutellarin significantly reversed hypoxia-promoted epithelial-mesenchymal transition (EMT) in BC cells and the PI3K/Akt and MAPK pathways were implicated in the suppressive effect. Taken together, we suggested the potential value of Scutellarin as a novel anticancer agent for BC treatment.

摘要

野黄芩苷是黄酮类的一种活性成分,具有多种生理作用,已被应用于治疗包括高血压、脑梗死和脑卒中等多种疾病。最近,野黄芩苷已被证明具有抗癌活性。但野黄芩苷在膀胱癌(BC)中的生物学意义仍有待阐明。在本研究中,我们探讨了野黄芩苷对 BC 进展的具体作用。我们发现,野黄芩苷可抑制体外低氧诱导的 BC 细胞迁移和侵袭,并抑制体内低氧诱导的 BC 转移。此外,野黄芩苷可显著逆转 BC 细胞中低氧诱导的上皮-间充质转化(EMT),PI3K/Akt 和 MAPK 通路参与了这种抑制作用。综上所述,我们认为野黄芩苷作为一种新型抗癌药物,可能具有治疗膀胱癌的潜在价值。
