<strong>Cyclin D</strong>（细胞周期蛋白 D）是细胞周期 G1 期的核心调控蛋白家族，包含三个高度同源的成员：<strong>Cyclin D1</strong>、<strong>Cyclin D2</strong> 和 <strong>Cyclin D3</strong>。<br />
</p><br />
<p style="font-size: 1.1em; margin: 0 0 25px 0; color: #334155; text-align: justify;"><br />
与后续的 Cyclin E 或 A 不同，Cyclin D 的合成完全依赖于细胞外的<strong>有丝分裂原</strong>（Mitogens）信号（如 EGF, IGF）。因此，它被视为细胞感知外部环境、决定是否进行分裂的“传感器”。它与 <strong>[[CDK4/6]]</strong> 结合形成活性复合物，磷酸化 <strong>[[Rb]]</strong> 蛋白，从而开启细胞周期的第一步。Cyclin D1 的异常扩增或易位是<strong>[[套细胞淋巴瘤]]</strong>和<strong>[[乳腺癌]]</strong>的关键驱动事件。<br />

Cyclin D 的表达水平是细胞内外信号通路的交汇点，特别是 <strong>RAS/MAPK</strong> 和 <strong>PI3K/AKT</strong> 通路：<br />

<li style="margin-bottom: 12px;"><br />
<strong>合成（油门）：</strong> <br />
当生长因子（如 EGF）结合受体后，信号传导至核内，启动 <em>CCND</em> 基因的转录。mRNA 迅速翻译成 Cyclin D 蛋白，并与 <strong>[[CDK4/6]]</strong> 结合。<br />
</li><br />
<li style="margin-bottom: 12px;"><br />
<strong>降解（刹车）：</strong> <br />
Cyclin D 非常不稳定（半衰期仅 20 分钟）。当生长因子撤去后，激酶 <strong>GSK3β</strong> 会磷酸化 Cyclin D，标记其被降解。这确保了细胞一旦脱离生长环境，就能立即停止分裂。<br />

<strong>机制：</strong> 95% 以上的 MCL 患者会发生染色体易位 <strong>t(11;14)(q13;q32)</strong>。这次易位将位于 11 号染色体的 <em>CCND1</em> 基因，搬运到了位于 14 号染色体的 <strong>IgH</strong>（免疫球蛋白重链）基因增强子附近。由于 B 细胞会持续高表达 IgH，导致 Cyclin D1 被错误地持续激活，驱动淋巴细胞无限增殖。<br />
