年龄是多形性胶质母细胞瘤（GBM）患者生存的一个强有力的预测因素，但其临床结果差异的生物学基础尚不清楚。发现可以解释年龄特异性生存差异的基因和途径可以为GBM的新疗法带来机会。在这里，我们整合了癌症基因组图谱（TCGA）项目中一组GBM患者的基因表达、外显子表达、microRNA表达、拷贝数改变、SNP、全外显子序列和DNA甲基化数据集，以发现转录、遗传和表观遗传水平上的年龄特异性特征，并在REMBRANDT数据集上验证了我们的发现。我们在所有水平上发现了主要的年龄特异性特征，包括多梳组蛋白靶基因的年龄特异性高甲基化和老年GBMs中血管生成相关基因的上调。这些与分子亚型无关的GBM的年龄特异性差异可能部分解释了抗血管生成药物在老年GBM中的优先作用，并为更好地理解老年GBM与年轻GBM的独特生物学和临床行为铺平了道路。
Age is a powerful predictor of survival in glioblastoma multiforme (GBM) yet the biological basis for the difference in clinical outcome is mostly unknown. Discovering genes and pathways that would explain age-specific survival difference could generate opportunities for novel therapeutics for GBM. Here we have integrated gene expression, exon expression, microRNA expression, copy number alteration, SNP, whole exome sequence, and DNA methylation data sets of a cohort of GBM patients in The Cancer Genome Atlas (TCGA) project to discover age-specific signatures at the transcriptional, genetic, and epigenetic levels and validated our findings on the REMBRANDT data set. We found major age-specific signatures at all levels including age-specific hypermethylation in polycomb group protein target genes and the upregulation of angiogenesis-related genes in older GBMs. These age-specific differences in GBM, which are independent of molecular subtypes, may in part explain the preferential effects of anti-angiogenic agents in older GBM and pave the way to a better understanding of the unique biology and clinical behavior of older versus younger GBMs.
