<strong>非突变表观遗传重编程</strong>（Nonmutational Epigenetic Reprogramming）是<strong>[[癌症十四大特征]]</strong>（Hallmarks of Cancer v3.0, 2022）中新增的独立特征之一。它描述了一种现象：在没有<strong>[[DNA序列]]</strong>突变的情况下，癌细胞通过全面改变<strong>[[DNA甲基化]]</strong>模式、<strong>[[组蛋白修饰]]</strong>以及染色质构象，来调控基因表达，从而获得恶性能力。这种“软件层面”的重写赋予了癌细胞极高的<strong>[[表型可塑性]]</strong>，使其能够去分化为干细胞样状态、跨谱系转分化，并逃避药物的杀伤。这一机制解释了为何许多肿瘤在基因组相对稳定的情况下，依然表现出高度的<strong>[[肿瘤异质性]]</strong>和侵袭性。<br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
表观遗传重编程允许癌细胞在不改变基因组“硬件”的情况下，通过重写“软件”来获得生存优势。这主要通过以下三种机制实现：<br />
</p><br />
<br />
<div style="margin-bottom: 25px; border: 1px solid #e2e8f0; border-radius: 8px; padding: 20px; background-color: #f8fafc;"><br />
<h3 style="margin-top: 0; color: #1e40af; font-size: 1.1em; border-bottom: 1px solid #e2e8f0; padding-bottom: 10px;">1. 诱导微环境压力适应 (Microenvironmental Adaptation)</h3><br />
<p style="text-align: justify; color: #334155; font-size: 0.95em;"><br />
当癌细胞面临[[缺氧]] (Hypoxia) 时，<strong>[[HIF-1α]]</strong> 不仅调节代谢，还会诱导 <strong>[[TET酶]]</strong> 活性改变，导致特定位点的 DNA 去甲基化。这种重编程使得细胞能够开启“生存模式”基因，即使在恶劣条件下也能存活。<br />
</p><br />
</div><br />
<br />
<div style="margin-bottom: 25px; border: 1px solid #e2e8f0; border-radius: 8px; padding: 20px; background-color: #ffffff;"><br />
<h3 style="margin-top: 0; color: #b91c1c; font-size: 1.1em; border-bottom: 1px solid #e2e8f0; padding-bottom: 10px;">2. 驱动表型可塑性 (Driving Phenotypic Plasticity)</h3><br />
<p style="text-align: justify; color: #334155; font-size: 0.95em;"><br />
这是该特征最致命的后果。通过 <strong>[[EZH2]]</strong> (组蛋白甲基转移酶) 介导的 H3K27me3 修饰，癌细胞可以关闭分化基因，逆向<strong>[[去分化]]</strong>为干细胞样状态（Stem-like state），或者<strong>[[转分化]]</strong>为另一种细胞类型。<br />
<br><em>实例：</em> [[前列腺癌]]通过表观遗传重编程关闭雄激素受体表达，转变为[[神经内分泌癌]] (NEPC)，从而逃避激素疗法。<br />

<p style="text-align: justify; color: #334155; font-size: 0.95em;"><br />
全基因组范围内的<strong>[[低甲基化]]</strong> (Global Hypomethylation) 会激活本应沉默的转座子（如 LINE-1），导致染色体断裂和易位。这意味着表观遗传的混乱可以反过来引发遗传学上的突变（赋能特征的交互作用）。<br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
表观遗传重编程不仅仅是理论概念，它直接催生了一类新型抗癌药物——<strong>表观遗传药物</strong> (Epidrugs)。<br />
