场效应和先驱基因驱动膀胱癌的发生
常见的上皮癌是由发育不良或原位癌演变而来的,这一观点因在外观正常的细胞中发现隐性疾病(称为场效应)而受到质疑,场效应涉及可能在粘膜上形成大斑块的区域。在发表于《细胞报告》(Cell Reports)上的一项新研究中,作者们开发了一种创新的全器官图谱绘制方法,该方法与基因组标记相结合,有助于剖析肿瘤前克隆最初克隆扩增的事件序列。这一策略被用于识别肿瘤抑制因子 RB1 周围区域的 FR 基因。研究发现,多态性缺失与肿瘤前克隆的早期克隆扩增有关的最小区段为 1.7 Mb,其中包括 20 个推测的候选基因。通过对 RB1 周围 5 Mb 区段的表达研究,确定了五个 FR 基因,这些基因在 50%的样本中表达下调至少两倍:ITM2B、LPAR6、MLNR、CAB39L和ARL11。高甲基化被确定为这些基因沉默的主要机制。
