Hyperoside is a natural flavonol glycoside widely found in plants and has been reported to have a variety of pharmacological effects, including anticancer abilities. In this study, we demonstrated for the first time that hyperoside inhibited the proliferation of bladder cancer cells in vitro and in vivo. Moreover, hyperoside could not only induce cell cycle arrest, but also induce apoptosis of a few bladder cancer cells. Quantitative proteomics, bioinformatics analysis and Western blotting confirmed that hyperoside induced the overexpression of EGFR, Ras and Fas proteins, which affects a variety of synergistic and antagonistic downstream signaling pathways, including MAPKs and Akt, ultimately contributing to its anticancer effects in bladder cancer cells. This study reveals that hyperoside could be a promising therapeutic strategy for the prevention of bladder cancer.
金丝桃苷是一种广泛存在于植物中的天然黄酮醇苷,据报道具有多种药理作用,包括抗癌能力。在本研究中,我们首次证明金丝桃苷在体外和体内均能抑制膀胱癌细胞的增殖。此外,金丝桃苷不仅能诱导细胞周期停滞,还能诱导一些膀胱癌细胞凋亡。定量蛋白质组学、生物信息学分析和蛋白质印迹法证实,金丝桃苷诱导表皮生长因子受体(EGFR)、Ras和Fas蛋白的过表达,这影响了包括丝裂原活化蛋白激酶(MAPKs)和蛋白激酶B(Akt)在内的多种协同和拮抗的下游信号通路,最终促成其对膀胱癌细胞的抗癌作用。本研究表明,金丝桃苷可能是预防膀胱癌的一种有前景的治疗策略。
