雄激素受体 (AR) 和 MNK 激活的 eIF4E 信号传导促进前列腺癌 (PCa) 的发生和进展。在这项研究中,我们报告说,我们的新型视黄酰胺 (NR) 通过泛素蛋白酶体途径增强 AR 和 MNK 降解,从而靶向雄激素敏感和去势抵抗性 PCa 细胞中的 AR 信号传导和 eIF4E 翻译。 AR 和 MNK 的双重阻断引发 NR 激活 eIF4E,进而诱导细胞周期停滞、细胞凋亡并抑制细胞增殖。 NR 还抑制转移细胞的细胞迁移和侵袭。重要的是,NR 对 AR 信号传导、eIF4E 翻译起始和随后的致癌程序的抑制作用比临床相关维甲酸、已建立的 MNK 抑制剂和 FDA 批准的 PCa 药物观察到的效果更有效。我们的研究结果提供了第一个临床前证据,表明同时抑制 AR 和 eIF4E 激活是一种新颖且有效的 PCa 治疗方法,并且 NR 对治疗晚期前列腺癌具有重要前景。
Androgen receptor (AR) and MNK activated eIF4E signaling promotes the development and progression of prostate cancer (PCa). In this study, we report that our Novel Retinamides (NRs) target both AR signaling and eIF4E translation in androgen sensitive and castration resistant PCa cells via enhancing AR and MNK degradation through ubiquitin-proteasome pathway. Dual blockade of AR and MNK initiated eIF4E activation by NRs in turn induced cell cycle arrest, apoptosis, and inhibited cell proliferation. NRs also inhibited cell migration and invasion in metastatic cells. Importantly, the inhibitory effects of NRs on AR signaling, eIF4E translation initiation and subsequent oncogenic program were more potent than that observed with clinically relevant retinoids, established MNK inhibitors, and the FDA approved PCa drugs. Our findings provide the first preclinical evidence that simultaneous inhibition of AR and eIF4E activation is a novel and efficacious therapeutic approach for PCa, and that NRs hold significant promise for treatment of advanced prostate cancer.
