转录因子(TF)通常以组合方式协调基因表达的开和关状态。对胚胎干细胞和其他细胞类型的研究表明,一群自我调节的核心TF控制细胞身份和细胞状态。这些核心转录因子形成相互连接的前馈转录环,以建立和加强细胞类型特异性基因表达程序;核心转录因子及其调控环的集合构成核心转录调控电路(CRC)。在这里,我们总结了最近的进展,在各种人类恶性肿瘤的CRC的计算重建和生物学探索,并巩固CRC发现的策略和方法。我们还讨论了CRC的遗传基础和治疗的脆弱性,并强调了新的前沿和未来的努力,为癌症中的CRC研究。癌症中CRC的知识对于理解癌症特异性转录成瘾是至关重要的,并且应该为病理生物学和治疗学提供重要的见解。
Transcription factors (TFs) coordinate the on-and-off states of gene expression typically in a combinatorial fashion. Studies from embryonic stem cells and other cell types have revealed that a clique of self-regulated core TFs control cell identity and cell state. These core TFs form interconnected feed-forward transcriptional loops to establish and reinforce the cell-type-specific gene-expression program; the ensemble of core TFs and their regulatory loops constitutes core transcriptional regulatory circuitry (CRC). Here, we summarize recent progress in computational reconstitution and biologic exploration of CRCs across various human malignancies, and consolidate the strategy and methodology for CRC discovery. We also discuss the genetic basis and therapeutic vulnerability of CRC, and highlight new frontiers and future efforts for the study of CRC in cancer. Knowledge of CRC in cancer is fundamental to understanding cancer-specific transcriptional addiction, and should provide important insight to both pathobiology and therapeutics.
