芍药苷 (PF) 是从芍药中分离出来的天然化合物,已被证明对包括神经胶质瘤在内的多种人类癌症具有抗肿瘤作用。然而,其作用机制尚不清楚。 S 期激酶相关蛋白 (Skp)2 在许多癌症中充当癌基因。在本研究中,我们研究了 Skp2 是否介导 PF 的抗神经胶质瘤活性。我们发现PF抑制神经胶质瘤细胞的增殖、迁移和侵袭,并诱导G2/M期阻滞和细胞凋亡。 PF 处理的神经胶质瘤细胞中 Skp2 表达下调。 PF 在神经胶质瘤细胞中诱导的抗肿瘤作用被 Skp2 过表达所消除,但通过 Skp2 的 RNA 干扰而增强。此外,PF 治疗可抑制异种移植小鼠模型中 U87 细胞衍生的肿瘤生长。这些结果表明,PF 部分通过抑制神经胶质瘤细胞中 Skp2 的表达来发挥其抗肿瘤作用,并且可能成为神经胶质瘤治疗的有前途的治疗剂。
Paeoniflorin (PF), a natural compound isolated from Paeoniae radix, has been shown to exert antitumor effects in various types of human cancers including glioma. However, the mechanism of action is not well understood. S-phase kinase-associated protein (Skp)2 functions as an oncogene in many cancers. In the present study, we investigated whether Skp2 mediates the anti-glioma activity of PF. We found that PF inhibited glioma cell proliferation, migration and invasion, and induced G2/M arrest and apoptosis. Skp2 expression was downregulated in glioma cells treated with PF. PF-induced antitumor effects in glioma cells were abolished by Skp2 overexpression but were enhanced by RNA interference of Skp2. Moreover, PF treatment inhibited U87 cell-derived tumor growth in a xenograft mouse model. These results demonstrate that PF exerts its antitumor effects in part by inhibiting Skp2 expression in glioma cells and could be a promising therapeutic agent for glioma therapy.
