Cell Discovery:复旦大学詹成/范虹等提出基于铁死亡的肺癌治疗新策略
生物世界· 2025-10-08 04:04
撰文丨王聪 编辑丨王多鱼 排版丨水成文 肺癌 是一种极为常见的恶性肿瘤,是全球癌症相关死亡的主要原因。值得注意的是, 非小细胞肺癌 (NSCLC) 约占所有肺癌病例的 85%,其中 肺腺癌 (LUAD) 是最常见的亚型。尽管癌症治疗方面近来有所进展,但肺腺癌患者的预后仍然不佳,五年生存率低于 26%。 乳酸化修饰 ( lactylation ) 是一种由 乳酸 (LA) 介导的蛋白质翻译后修饰,因其在表观遗传调控中的关键作用而备受关注。然而,乳酸化修饰与 铁死亡 在 肺腺癌 (LUAD) 中的复杂相互作用,仍有待全面阐明。 2025 年 10 月 7 日,复旦大学附属中山医院 詹成 、 范虹 、 Bi Guoshu 等人在 Cell Discovery 期刊发表了题为 : Ferroptosis-induced SUMO2 lactylation counteracts ferroptosis by enhancing ACSL4 degradation in lung adenocarcinoma 的研究论文。 该研究表明, 铁死亡 诱导的 SUMO2 乳酸化修饰 ,通过增强 肺腺癌 中 ACSL4 的降解 ...

Core Viewpoint - The study highlights the role of C19orf12 as a mitochondrial metabolic regulator in non-small cell lung cancer (NSCLC), indicating that elevated expression levels may serve as a biomarker for improved response to metformin treatment [10]. Group 1: Research Findings - C19orf12 is highly expressed in NSCLC and is associated with poor prognosis [7]. - C19orf12 regulates mitochondrial function and drives glucose metabolic reprogramming [7]. - C19orf12 interacts with LRPPRC protein, downregulating the expression of mitochondrial electron transport chain complexes I and IV [7]. - High levels of C19orf12 inhibit mitochondrial respiration and reduce glucose flux through the tricarboxylic acid (TCA) cycle [5][6]. Group 2: Implications for Treatment - C19orf12 enhances the sensitivity of NSCLC cells to the antitumor effects of metformin [6]. - The study suggests that C19orf12 expression levels could predict the response to metformin treatment in NSCLC patients [10].
