项目摘要
BRAF (V600E) is the common oncogenic driver mutation in 60-70% of melanoma patients. Melanoma cells that have BRAF (V600E) mutation accumulated aberrant gene suppression through the histone-chromatin modification, and subsequently the aberrancy was well correlated with metastatic potentials of examined melanoma cells. The histone deacetylase inhibitor (HDACi) is a potent agent to improve the aberrantly deacetylated-histones. Some of HDACi were able to improve levels of deacetylated-histones and sensitized melanoma cells to the therapeutic cell death partially. Unfortunately the effects of HDACi did not always appear sufficient for BRAF (V600E)-positive melanoma cells. Thus, it is necessary to think the possibility that BRAF (V600E)-mediated constitutive activation may maintain the abnormal histone methylation, and that particular gene amplification accompanied with melanoma development may be involved in the therapeutic resistance.
BRAF (V600E) 是 60-70% 黑色素瘤患者常见的致癌驱动突变。具有 BRAF (V600E) 突变的黑色素瘤细胞通过组蛋白染色质修饰积累了异常基因抑制,随后这种异常与所检查的黑色素瘤细胞的转移潜能密切相关。组蛋白脱乙酰酶抑制剂 (HDACi) 是改善异常脱乙酰组蛋白的有效药物。一些 HDACi 能够提高脱乙酰组蛋白的水平,并使黑色素瘤细胞对治疗性细胞死亡部分敏感。不幸的是,HDACi 对于 BRAF (V600E) 阳性黑色素瘤细胞的作用并不总是足够。因此,有必要考虑BRAF(V600E)介导的组成性激活可能维持异常的组蛋白甲基化,并且伴随黑色素瘤发展的特定基因扩增可能与治疗抵抗有关。
