Abstract

CUDC-101, an effective and multi-target inhibitor of epidermal growth factor receptor (EGFR), histone deacetylase (HDAC), and human epidermal growth factor receptor 2 (HER2), has been reported to inhibit many kinds of cancers, such as acute promyelocytic leukemia and non-Hodgkin's lymphoma. However, no studies have yet investigated whether CUDC-101 is effective against myeloma. Herein, we proved that CUDC-101 effectively inhibits the proliferation of multiple myeloma (MM) cell lines and induces cell apoptosis in a time- and dose-dependent manner. Moreover, CUDC-101 markedly blocked the signaling pathway of EGFR/phosphoinositide-3-kinase (PI3K) and HDAC, and regulated the cell cycle G2/M arrest. Moreover, we revealed through in vivo experiment that CUDC-101 is a potent anti-myeloma drug. Bortezomib is one of the important drugs in MM treatment, and we investigated whether CUDC-101 has a synergistic or additive effect with bortezomib. The results showed that this drug combination had a synergistic anti-myeloma effect by inducing G2/M phase blockade. Collectively, our findings revealed that CUDC-101 could act on its own or in conjunction with bortezomib, which provides insights into exploring new strategies for MM treatment.

多发性骨髓瘤(MM)是一种高度异质性的疾病。硼替佐米作为第一代蛋白酶体抑制剂,大大提高了MM的治疗效果和疾病预后,延长了患者的总生存期和生活质量。然而,部分患者在接受硼替佐米治疗后仍会出现疾病复发和进展,且由硼替佐米引起的周围神经病变严重影响了患者的生活质量。因此,寻找新的MM治疗药物,或减少硼替佐米治疗的副作用,对MM患者是一个非常重要的临床需求。本研究旨在探索表皮生长因子受体(EGFR)和组蛋白去乙酰化酶(HDAC)双靶点抑制剂CUDC-101对MM治疗的潜在疗效,并阐述其潜在机制。结果表明,CUDC-101可通过抑制EGFR/PI3K和HDAC信号通路,诱导MM细胞系或原代CD138阳性MM细胞的细胞周期阻滞,显著抑制细胞增殖,诱导细胞凋亡。同时,CUDC-101在MM异种移植物模型中也表现出明显的生长抑制作用。此外,我们证实了CUDC-101和治疗MM的最常用的药物之一硼替佐米之间的协同作用。利用MM细胞系和异种移植模型,我们还发现了它可以显著抑制细胞增殖和肿瘤生长。总之,我们确定了CUDC-101在单药或联合硼替佐米治疗MM中的有效性。这一结果为MM患者的治疗提供了一种新的策略。.
