神经母细胞瘤是儿童最常见的实体瘤之一。到目前为止,靶向MYCN,一个在高危神经母细胞瘤中已经确立的驱动基因,仍然是具有挑战性的。近年来,抑制溴结构域和额外末端(BET)蛋白在多种Myc驱动的肿瘤中显示出巨大的潜力。ARV-825是一种新型的BET抑制剂,采用蛋白水解靶向嵌合体(PROTAC)技术,通过蛋白酶体降解靶蛋白。在本研究中,我们研究了ARV-825在体外和体内对神经母细胞瘤的作用。我们的结果表明,ARV-825处理能强烈地诱导NB细胞的增殖抑制、细胞周期停滞和细胞凋亡。此外,ARV-825可有效抑制BET蛋白的表达,进而抑制MYCN或c-Myc的表达。在NB异种移植模型中,ARV-825显著抑制了小鼠肿瘤的生长,并下调了BRD4和MYCN的表达。综上所述,这些发现为PROTAC BET抑制剂是实现MYCN/c-Myc调控的有效途径提供了证据,ARV-825可以作为治疗神经母细胞瘤的潜在治疗策略。
Neuroblastoma (NB) is one of the most common solid tumors in childhood. To date, targeting MYCN, a well-established driver gene in high-risk neuroblastoma, is still challenging. In recent years, inhibition of bromodomain and extra terminal (BET) proteins shows great potential in multiple of Myc-driven tumors. ARV-825 is a novel BET inhibitor using proteolysis-targeting chimera (PROTAC) technology which degrades target proteins by the proteasome. In this study, we investigated the effect of ARV-825 in neuroblastoma in vitro and in vivo. Our results showed that ARV-825 treatment robustly induced proliferative suppression, cell cycle arrest, and apoptosis in NB cells. Moreover, ARV-825 efficiently depleted BET protein expression, subsequently repressing the expression of MYCN or c-Myc. In the NB xenograft model, ARV-825 profoundly reduced tumor growth and led to the downregulation of BRD4 and MYCN expression in mice. Taken together, these findings provide evidence that PROTAC BET inhibitor is an efficient way to achieve MYCN/c-Myc manipulation, and ARV-825 can be used as a potential therapeutic strategy for the treatment of neuroblastoma.
