研究目的:

主要目的: 1. 探索高级别浆液性卵巢癌(HGSOC)中过度乳酸化是否会直接重塑细胞骨架,从而驱动腹膜转移所需的独特物理特性。 2. 整合定量全局蛋白质组学、乳酸化蛋白质组学及单细胞 RNA 测序(scRNA-seq)技术,绘制 HGSOC 的代谢-结构图谱。 3. 明确 HGSOC 中的过度乳酸化特异性靶向非组蛋白细胞骨架蛋白,导致其不稳定化而非激活。 4. 通过药物靶向乳酸脱氢酶 A(LDHA)可有效降低乳酸化水平、恢复细胞骨架完整性、释放被隔离的 p62 蛋白,并逆转恶性阿米巴样表型。 5. 揭示卵巢癌中一种新型“代谢-结构”轴,提示靶向蛋白质乳酸化可作为治疗策略,通过重建细胞结构来抑制转移进程。 次要目的: 1. 证实这种由乳酸化驱动的肌动球蛋白网络崩塌会导致细胞内聚集体形成,这些聚集体物理隔离自噬受体 p62(SQSTM1),从而阻断自噬流。 2. 阐明乳酸化诱导的 RhoA-ROCK 信号轴和水通道蛋白-1(AQP1)下调促使 HGSOC 细胞进入不依赖蛋白酶的“阿米巴样”扩散模式。  

Objectives of Study:

Primary Objectives: 1. To explore whether hyperlactylation in high-grade serous ovarian cancer (HGSOC) directly remodels the cytoskeleton, thereby driving the unique physical properties required for peritoneal metastasis. 2. To integrate quantitative global proteomics, lactylated proteomics, and single-cell RNA sequencing (scRNA-seq) technologies to map the metabolic-structural atlas of HGSOC. 3. To clarify that hyperlactylation in HGSOC specifically targets non-histone cytoskeletal proteins, leading to their destabilization rather than activation. 4. To demonstrate that targeting lactate dehydrogenase A (LDHA) with drugs can effectively reduce lactylation levels, restore cytoskeletal integrity, release sequestered p62 protein, and reverse malignant amoeboid phenotypes. 5. To reveal a novel "metabolism-structure" axis in ovarian cancer, suggesting that targeting protein lactylation could be a therapeutic strategy to inhibit metastasis by reconstructing cell structure. Secondary Objectives: 1. To confirm that this lactylation-driven collapse of the actomyosin network leads to the formation of intracellular aggregates that physically sequester the autophagy receptor p62 (SQSTM1), thereby blocking autophagic flux. 2. To elucidate that lactylation-induced RhoA-ROCK signaling axis and downregulation of aquaporin-1 (AQP1) promote HGSOC cells to enter a protease-independent "amoeboid" mode of dissemination.
