识别与关键癌基因合作以促进转化的遗传改变谱为理解在人类癌症中观察到的临床表型的多样性提供了基础。在这里，我们进行了综合分析，以确定在黑色素瘤中与致癌BRAF共同发生的基因组改变，并消除细胞对该致癌基因的依赖。我们确定了PTEN和RB 1肿瘤抑制因子的同时突变失活是携带V600 EBRAF突变的黑色素瘤中BRAF/MEK依赖性丧失的机制。RB 1的改变与p16 INK 4A的缺失是相互排斥的，这表明p16 INK 4A和RB 1在预防肿瘤形成方面可能具有重叠的作用，而RB 1缺失的肿瘤表现出对BRAF信号传导的依赖性降低。这些发现为使用丝裂原活化蛋白激酶通路靶向抑制剂治疗的患者的临床结局异质性提供了遗传学基础。我们的研究结果还表明，需要对接受RAF和MEK选择性抑制剂治疗的患者进行RB 1和PTEN失活的全面筛查，以确定这些改变是否与携带突变型BRAF的癌症患者的临床获益减少相关。
Identifying the spectrum of genetic alterations that cooperate with critical oncogenes to promote transformation provides a foundation for understanding the diversity of clinical phenotypes observed in human cancers. Here, we performed integrated analyses to identify genomic alterations that co-occur with oncogenic BRAF in melanoma and abrogate cellular dependence upon this oncogene. We identified concurrent mutational inactivation of the PTEN and RB1 tumor suppressors as a mechanism for loss of BRAF/MEK dependence in melanomas harboring V600EBRAF mutations. RB1 alterations were mutually exclusive with loss of p16INK4A, suggesting that whereas p16INK4A and RB1 may have overlapping roles in preventing tumor formation, tumors with loss of RB1 exhibit diminished dependence upon BRAF signaling for cell proliferation. These findings provide a genetic basis for the heterogeneity of clinical outcomes in patients treated with targeted inhibitors of the mitogen-activated protein kinase pathway. Our results also suggest a need for comprehensive screening for RB1 and PTEN inactivation in patients treated with RAF and MEK-selective inhibitors to determine whether these alterations are associated with diminished clinical benefit in patients whose cancers harbor mutant BRAF.
