铁是细胞功能必需的微量营养素金属,但会产生高活性氧,导致氧化损伤。由于这些原因,它的吸收和代谢受到高度调节。细胞内一小部分但动态的二价铁,称为细胞内不稳定铁,具有氧化还原反应性,并准备参与细胞内酶的多重反应。由于其性质,其测定和精确量化一直是一个障碍。然而,细胞内不稳定铁探针开发的最新进展使我们能够重新评估我们目前的理解并揭示新功能。最近发现了细胞内不稳定铁在调节表观基因组中的作用。本章研究细胞内不稳定铁如何调节组蛋白和 DNA 去甲基化,以及其池如何介导 cAMP 的信号传导途径,作为细胞代谢需求的传感器。
Iron is an essential micronutrient metal for cellular functions but can generate highly reactive oxygen species resulting in oxidative damage. For these reasons its uptake and metabolism is highly regulated. A small but dynamic fraction of ferrous iron inside the cell, termed intracellular labile iron, is redox-reactive and ready to participate multiples reactions of intracellular enzymes. Due to its nature its determination and precise quantification has been a roadblock. However, recent progress in the development of intracellular labile iron probes are allowing the reevaluation of our current understanding and unmasking new functions. The role of intracellular labile iron in regulating the epigenome was recently discovered. This chapter examine how intracellular labile iron can modulate histone and DNA demethylation and how its pool can mediate a signaling pathway from cAMP serving as a sensor of the metabolic needs of the cells.
