**“基于丁酸钠调控组蛋白乳酸化通路干预卵巢癌细胞干性的新机制探索”**

### 背景：

卵巢癌是一种高度恶性的癌症，其复发率和耐药性使得其在临床治疗上面临重大挑战。肿瘤相关成纤维细胞（Tumor-Associated Fibroblasts，TAFs）在肿瘤微环境中起着重要作用，促进癌细胞的生长和迁移，并通过组蛋白乳酸化等表观遗传途径增强癌细胞干性。近年来，丁酸钠作为一种组蛋白去乙酰化酶抑制剂（HDACi）被证明在癌症干预中具有显著的抑癌潜力。然而，丁酸钠如何通过抑制TAFs介导的组蛋白乳酸化影响卵巢癌细胞的干性，仍需深入研究。

### 目前研究难点：

1. **微环境调控的复杂性**：TAFs在肿瘤微环境中与癌细胞的相互作用多样，涉及多条信号通路和表观遗传调控机制，尚不完全明确。

2. **组蛋白乳酸化机制不明**：组蛋白乳酸化在癌细胞干性中的作用研究较少，缺乏清晰的分子机制和作用通路解析。

3. **丁酸钠的多重效应**：丁酸钠对不同癌细胞类型表现出不同的细胞毒性和调控作用，具体在卵巢癌细胞干性中的影响尚未明了。

### 创新点：

1. **探索丁酸钠在组蛋白乳酸化的特异调控**：首次研究丁酸钠如何通过表观遗传通路特异性抑制TAFs诱导的组蛋白乳酸化，抑制卵巢癌干性。

2. **揭示丁酸钠对TAFs和癌细胞相互作用的双重作用**：丁酸钠不仅直接作用于癌细胞，还通过影响TAFs在肿瘤微环境中的作用，从而间接抑制癌细胞干性。

3. **建立卵巢癌干性调控的多层次机制模型**：从分子水平到细胞行为，系统性解析丁酸钠在卵巢癌干性调控中的作用机制。

### 拟解决的科学问题：

1. 丁酸钠是否通过抑制TAFs介导的组蛋白乳酸化来降低卵巢癌细胞的干性？

2. 组蛋白乳酸化在TAFs诱导的卵巢癌干性中的具体作用机制是什么？

3. 丁酸钠通过何种途径抑制卵巢癌干性，并且能否有效减缓癌症进展？

### 科学假说：

我们假设丁酸钠通过抑制肿瘤相关成纤维细胞（TAFs）诱导的组蛋白乳酸化，从而抑制卵巢癌细胞的干性。具体而言，丁酸钠可能通过调控组蛋白乳酸化相关基因表达、降低癌细胞干性标志物的表达，最终抑制卵巢癌细胞的增殖和迁移能力。
