Mitogen-activated protein kinase phosphatase 1 (MKP1 or DUSP1) is an antiapoptotic phosphatase that is overexpressed in many cancers, including breast cancer. MKP1 expression is inducible in radiation-treated breast cancer cells, and correlates with human epidermal growth factor receptor 2 (ERBB2, HER2) expression. The role of MKP1 in therapy resistance suggests that targeting MKP1 in HER2-positive breast tumors may significantly enhance the efficacy of anti-HER2 and other anticancer therapies.
丝裂原活化蛋白激酶磷酸酶1(MKP1或DUSP1)是一种抗凋亡磷酸酶,在包括乳腺癌在内的许多癌症中均有过表达。MKP1在接受放疗的乳腺癌细胞中可被诱导表达,且与人类表皮生长因子受体2(ERBB2,HER2)的表达相关。MKP1在治疗耐药性中的作用表明,在HER2阳性乳腺肿瘤中靶向作用于MKP1可能会显著提高抗HER2及其他抗癌疗法的疗效。
