癌性肿瘤包含一种罕见的具有干细胞样特性的细胞亚群,称为癌症干细胞(CSCs)。CSCs的定义是它们具有对称和不对称分裂、启动新肿瘤生长和耐受转移性传播所需的外来生态位的能力。越来越多的证据表明,肿瘤起源于具有干细胞样特性的细胞,因此csc的产生可能是癌变的起始事件。此外,已建立的肿瘤中的CSCs以动态和可塑性状态存在,非干细胞肿瘤细胞被认为能够向CSCs去分化。在肿瘤起始和已建立的肿瘤中,CSC状态的调节是一个理想的治疗靶点,并由表观遗传因素介导。在这篇综述中,我们将探讨诱导多能性和CSCs生成之间的表观遗传学相似性,并讨论CSCs的表观遗传学调控如何为治疗干预开辟新的机会。
Cancerous tumours contain a rare subset of cells with stem‐like properties that are termed cancer stem cells (CSCs). CSCs are defined by their ability to divide both symmetrically and asymmetrically, to initiate new tumour growth and to tolerate the foreign niches required for metastatic dissemination. Accumulating evidence suggests that tumours arise from cells with stem‐like properties, the generation of CSCs is therefore likely to be an initiatory event in carcinogenesis. Furthermore, CSCs in established tumours exist in a dynamic and plastic state, with nonstem tumour cells thought to be capable of de‐differentiation to CSCs. The regulation of the CSC state both during tumour initiation and within established tumours is a desirable therapeutic target and is mediated by epigenetic factors. In this review, we will explore the epigenetic parallels between induced pluripotency and the generation of CSCs, and discuss how the epigenetic regulation of CSCs opens up novel opportunities for therapeutic intervention.
