Bioactivity Rubone, a chalcone analog, is a modulator of miR-34a. Rubone upregulates miR-34a expression in a p53 dependent manner, downregulates the downstream target Bcl-2 and Cyclin D1 expression, and suppresses hepatocellular carcinoma (HCC) growth in vivo. Rubone enhanced the anticancer effect of Paclitaxel (PTX; HY-B0015) in PTX-resistant prostate cancer cell lines by reversing the expression of miR-34a downstream targets[1][2][3].
Invitro Rubone (0-60 μM) 在 DU145-TXR 和 PC3-TXR 细胞中表现出显着的细胞毒性,表明 Rubone 在晚期前列腺癌细胞中具有更强的抗癌作用,这些细胞具有较低的 miR-34a 表达[3]。 Rubone (5, 10 uM; 48 小时) 显着逆转 DU145-TXR 和 PC3-TXR 细胞系的 miR-34a 下游基因靶标的表达。Rubone 以剂量依赖性方式上调 PTX 抗性 DU145-TXR 和 PC3-TXR 细胞系中的 miR-34a[3]。 Rubone (5 μM; 持续 2 周) 和 PTX (持续 2 周) 联合疗法抑制 3D 模型中的 PC3-TXR 细胞生长和球体形成,包括顶部 3D 和悬滴模型。Rubone 和 PTX 联合疗法抑制 p53 独立途径中的细胞侵袭、迁移和癌症干细胞样细胞 (CSC) 种群。Rubone 单一疗法或 Rubone 与 PTX 组合可显着增强 TAp73 和 Elk-1 的表达[3]。 Cell Cytotoxicity Assay[3] Cell Line:
In Vivo Rubone 单一疗法 (装载 20 mg/kg 的 PEG-PCD 胶束; 每隔一天静脉注射;共五剂) 或与 PTX 联合治疗(PEG-PCD 胶束装载每种药物 10 mg/kg) 显着上调肿瘤中的 miR-34a 表达。联合疗法抑制肿瘤生长。Rubone 单一疗法未能抑制肿瘤细胞增殖[3]。 Animal Model:
