白血病药物的重新使用能够预防黑色素瘤的转移

2018-03-04 MedSci MedSci原创

一项最新研究的数据显示,重新使用治疗白血病的药物(ABL激酶抑制剂)有望预防黑色素瘤转移。该研究显示癌症促进基因ABL激酶的激活与黑素瘤中促转移性组织蛋白酶(pro-metastatic cathepsins)的分泌正向相关。组织蛋白酶能够降解蛋白质并在癌细胞中高度表达,肿瘤细胞将这些蛋白酶释放到细胞微环境中,这些酶“咀嚼”了肿瘤周围的纤维基质,进而使肿瘤细胞更容易地进入血液和淋巴系统并转移到身体

一项最新研究的数据显示,重新使用治疗白血病的药物(ABL激酶抑制剂)有望预防黑色素瘤转移。该研究显示癌症促进基因ABL激酶的激活与黑素瘤中促转移性组织蛋白酶(pro-metastatic cathepsins)的分泌正向相关。组织蛋白酶能够降解蛋白质并在癌细胞中高度表达,肿瘤细胞将这些蛋白酶释放到细胞微环境中,这些酶“咀嚼”了肿瘤周围的纤维基质,进而使肿瘤细胞更容易地进入血液和淋巴系统并转移到身体周围。

肯塔基大学Markey癌症中心的研究人员表示,ABL激酶通过上调多种关键转录因子的活性来诱导组织蛋白酶的表达和分泌。这项研究首次证明了ABL激酶不仅增加了转录因子的丰度,还调节了这些转录因子与启动子结合并诱导促转移性组织蛋白酶的基因表达。

最后,研究人员发现,美国食品和药物管理局(FDA)已批准用于治疗白血病的ABL激酶抑制剂也能抑制转移性黑素瘤动物模型分泌组织蛋白酶的能力。这一数据具有重要的治疗意义,因为ABL激酶抑制剂已成功用于治疗白血病,重新使用这些药物可能是治疗转移性黑色素瘤患者的有效方法。
