JEM:阻断CDK蛋白可导致三阴性乳腺癌萎缩

2012-03-23 MedSci MedSci原创

根据2012年3月9日发表在Journal of Experimental Medicine期刊上的一篇研究论文,抑制一种大量存在的促进生长的蛋白能够导致三阴性乳腺癌消退。 三阴性乳腺癌(triple-negative breast tumor)缺乏其他类型乳腺癌中存在的所有已知的可以作为治疗靶标的生长受体,这样也就使得它成为乳腺癌中最难治疗的疾病亚型。患上这种癌症的病人往往有着更短的无疾病存活

根据2012年3月9日发表在Journal of Experimental Medicine期刊上的一篇研究论文,抑制一种大量存在的促进生长的蛋白能够导致三阴性乳腺癌消退。

三阴性乳腺癌(triple-negative breast tumor)缺乏其他类型乳腺癌中存在的所有已知的可以作为治疗靶标的生长受体,这样也就使得它成为乳腺癌中最难治疗的疾病亚型。患上这种癌症的病人往往有着更短的无疾病存活期,而且肿瘤在他们身上也容易更早地复发。

如今,Andrei Goga和同事们发现三阴性乳腺癌表达高水平的促进生长的MYC蛋白。MYC活性是这些侵袭性肿瘤生长所必需的,因而阻断一种MYC协作性蛋白(MYC-cooperating protein),即CDK,导致小鼠中三阴性乳腺癌萎缩。

归纳在一起,这些结果鉴定出一种新的潜在性靶标用于治疗三阴性乳腺癌

  《细胞》(Cell)杂志近期在线发表的一项研究结果显示,PTPN12是一种通常呈失活状态的抑癌基因。PTPN12酪氨酸磷酸酯酶通过对三阴性乳腺癌(TNBC)和其他肿瘤的多种原癌基因酪氨酸激酶靶向作用而抑制肿瘤进展。   该研究通过基因筛查,确认PTPN12酪氨酸磷酸酯酶是一种TNBC抑癌因子。   PTPN12可有效抑制乳腺上皮细胞增殖和转移,在人TNBC患者中常处于失活状态。该研究确定了
