生酮和酮解是禁食反应期间激活的中心代谢过程。生酮过程受到多个阶段的调节,核受体过氧化物酶体增殖物激活受体α(PPARα)是参与该调节的关键转录因子之一。 PPARα 是代谢网络中的重要元素,它参与主要营养传感器驱动的信号传导,例如 AMP 激活蛋白激酶 (AMPK)、PPARγ 共激活剂 1α (PGC-1α) 和哺乳动物(机械)雷帕霉素靶标 (mTOR),并诱导激素介质,例如成纤维细胞生长因子 21 (FGF21)。这项工作描述了正常和恶性细胞中酮生成和酮解的调节,并简要总结了酮体在各种神经病理条件下的积极作用。
Ketogenesis and ketolysis are central metabolic processes activated during the response to fasting. Ketogenesis is regulated in multiple stages, and a nuclear receptor peroxisome proliferator activated receptor α (PPARα) is one of the key transcription factors taking part in this regulation. PPARα is an important element in the metabolic network, where it participates in signaling driven by the main nutrient sensors, such as AMP-activated protein kinase (AMPK), PPARγ coactivator 1α (PGC-1α), and mammalian (mechanistic) target of rapamycin (mTOR) and induces hormonal mediators, such as fibroblast growth factor 21 (FGF21). This work describes the regulation of ketogenesis and ketolysis in normal and malignant cells and briefly summarizes the positive effects of ketone bodies in various neuropathologic conditions.
