克雷布斯循环酶富马酸水合酶 (FH) 是一种人类肿瘤抑制因子,其失活与平滑肌瘤、肾囊肿和肿瘤的发展有关。有人提出,通过富马酸介导的 HIF 脯氨酰羟化酶抑制来激活缺氧诱导因子 (HIF),从而驱动肿瘤发生。使用小鼠模型,我们提供了遗传证据,证明 Fh1 相关囊肿形成与 Hif 无关,基因表达谱揭示的抗氧化信号通路的显着上调也是如此。机理分析表明,富马酸修饰 Kelch 样 ECH 相关蛋白 1 (KEAP1) 内的半胱氨酸残基,消除其抑制核因子(红细胞衍生 2)样 2 (Nrf2) 介导的抗氧化反应途径的能力,表明 Nrf2 失调在 FH 相关囊肿和肿瘤中发挥作用。 ► Fh1 相关肾囊肿形成独立于 Hif/Phd 通路 ► Fh1 丢失后,Nrf2 介导的抗氧化反应通路上调 ► 富马酸盐通过琥珀化修饰 Keap1 中的半胱氨酸残基
The Krebs cycle enzyme fumarate hydratase (FH) is a human tumor suppressor whose inactivation is associated with the development of leiomyomata, renal cysts, and tumors. It has been proposed that activation of hypoxia inducible factor (HIF) by fumarate-mediated inhibition of HIF prolyl hydroxylases drives oncogenesis. Using a mouse model, we provide genetic evidence that Fh1-associated cyst formation is Hif independent, as is striking upregulation of antioxidant signaling pathways revealed by gene expression profiling. Mechanistic analysis revealed that fumarate modifies cysteine residues within the Kelch-like ECH-associated protein 1 (KEAP1), abrogating its ability to repress the Nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-mediated antioxidant response pathway, suggesting a role for Nrf2 dysregulation in FH-associated cysts and tumors. ► Fh1-associated renal cyst formation is independent of Hif/Phd pathway ► Nrf2-mediated antioxidant response pathway is upregulated following Fh1 loss ► Fumarate modifies cysteine residues in Keap1 by succination
