摘要:

舒尼替尼(sunitinib, SUN)是一种多靶点酪氨酸激酶抑制剂(tyrosine kinase inhibitor, TKI), 在使用过程中会由于引发缺氧而增加肿瘤组织中的肿瘤干细胞(cancer stem-like cell, CSC)比例, 进而导致肿瘤的耐药和转移。本课题组研究证明, 多巴胺(dopamine, DA)可以通过激动多巴胺D1受体(D1 dopamine recpetor, D1DR)抑制耐药性乳腺癌和非小细胞肺癌中的CSC比例进而增强SUN的抗肿瘤药效。本研究考察了DASUN联合用药在胰腺癌中的抗肿瘤药效, 这是一种具有高致死率, 且药物治疗手段极其有限的恶性肿瘤。本研究的细胞毒实验、克隆形成实验和划痕实验结果显示该DA可以显著增强SUN对两种胰腺癌细胞PANC-1SW1990的细胞生存、克隆形成能力和迁移能力。采用SW1990细胞和胰腺癌患者组织分别构建体内移植瘤模型, 发现DA可以显著增强SUN的体内药效, 并可被D1DR特异性激动剂SCH23390部分逆转。此外, DA+SUN联合用药组肿瘤中的CSC比例显著低于空白对照组和SUN单药组。动物体重、主要脏器H&E染色和血常规检查结果显示各给药方案安全性良好。综上, DA可显著增强SUN体内外的抗胰腺癌药效, 且安全性良好。DASUN的联合用药组合具有用于胰腺癌治疗的巨大潜力。

Abstract:

Sunitinib (SUN) is a multi-targeted receptor tyrosine kinase inhibitor (TKI) that may lead to drug resistance and metastasis because of increased cancer stem-like cells (CSCs) due to the induction of hypoxia. Our group has proved that dopamine (DA) can specifically reduce CSC frequency and enhance the response of SUN in drug-resistant breast cancerand non-small cell lung cancer (NSCLC). In this study, DA and SUN combination therapy was investigated in the treatment of pancreatic cancer, a malignant tumor with high mortality rate and very limited therapies. The cytotoxicity assay, clone formation assay and wound healing assay in two pancreatic cancer cell line PANC-1 and SW1990 showed that DA could significantly increase the effect of SUN on cell survival, clone formation ability and migration ability. Besides, SW1990 cell-derived xenograft model and a pancreatic cancer patient-derived xenograft (PDX) model were constructed, further proving that DA could increase the in vivo anti-tumor efficacy of SUN, and could be reversed by SCH23390, a D1 dopamine receptor (D1DR) antagonist. Moreover, the CSC frequency of the combination groups was lower than the control groups or SUN monotherapy groups. In addition, the body weight, H&E staining and blood routine test results showed that the combination therapy was safe. In summary, DA and SUN combination therapy could be a promising strategy for the treatment of pancreatic cancer.
