BRAF和NRAS是良性和恶性肿瘤体细胞突变的共同靶点,这些肿瘤起源于上皮结构中的黑色素细胞,并导致map -激酶途径的组成性激活。然而,BRAF和NRAS突变在许多其他黑色素细胞肿瘤中不存在,在这些肿瘤中等效的致癌事件目前尚不清楚。我们报道了蓝痣(83%)和葡萄膜眼黑色素瘤(46%)中异源三聚体G蛋白α亚基(GNAQ)的频繁体细胞突变。突变只发生在ras-样结构域的密码子209上,导致组成性激活,使GNAQ成为显性的致癌基因。我们的研究结果证明了黑色素细胞瘤中map激酶激活的另一种途径,为治疗干预提供了新的机会。
BRAF and NRAS are common targets for somatic mutations in benign and malignant neoplasms that arise from melanocytes situated in epithelial structures and lead to constitutive activation of the MAP-kinase pathway. However, BRAF and NRAS mutations are absent in a number of other melanocytic neoplasms in which the equivalent oncogenic events are currently unknown. We report frequent somatic mutations in the heterotrimeric G protein alpha subunit, GNAQ, in blue nevi (83%) and ocular melanoma of the uvea (46%). The mutations occur exclusively in codon 209 in the ras-like domain and result in constitutive activation, turning GNAQ into a dominant acting oncogene. Our results demonstrate an alternative route to MAP-kinase activation in melanocytic neoplasia providing new opportunities for therapeutic intervention.
