胰岛素通过mTORC 2/AKT信号传导和GLUT 4易位刺激葡萄糖摄取进入脂肪细胞,并指导葡萄糖碳进入糖酵解、甘油和TAG合成以及从头脂肪生成。脂肪细胞胰岛素抵抗是2型糖尿病肥胖的早期指标,这是一个全球性的健康危机。因此,了解胰岛素信号传导和维持脂肪细胞功能、血糖水平和代谢稳态的中心碳代谢途径之间的相互作用至关重要。虽然传统上是通过单个酶-底物相互作用的透镜来观察的,但质谱法的进步正开始以前所未有的规模阐明脂肪细胞信号传导和代谢网络,但这只是冰山一角。在这里,我们回顾如何'组学方法有助于阐明脂肪细胞胰岛素的行动在细胞的时间和空间。
Insulin-stimulates glucose uptake into adipocytes via mTORC2/AKT signaling and GLUT4 translocation and directs glucose carbons into glycolysis, glycerol and TAG synthesis, and de novo lipogenesis. Adipocyte insulin resistance is an early indicator of type 2 diabetes in obesity, a worldwide health crisis. Thus, understanding the interplay between insulin signaling and central carbon metabolism pathways that maintains adipocyte function, blood glucose levels, and metabolic homeostasis is critical. While classically viewed through the lens of individual enzyme-substrate interactions, advances in mass spectrometry are beginning to illuminate adipocyte signaling and metabolic networks on an unprecedented scale, yet this is just the tip of the iceberg. Here we review how ‘omics approaches are helping to elucidate adipocyte insulin action in cellular time and space.
