Iron is an essential nutrient and is critical for cellular growth and metabolism. Here, we delineate a novel mechanism by which iron alters amino acid homeostasis and mTOR activity by remodeling the cellular epigenetic landscape. We find that iron deficiency inactivates Jumonji-C domain containing histone-demethylases, resulting in histone hyper-methylation and...
The electronic spin state (S) of metal ions is fundamental to the performance of magnets, protein cofactors, and magnetic resonance imaging (MRI) contrast agents. The ability to manipulate the spin state of transition metals allows for the development of advanced materials with emergent properties. This following chapters will introduce two...
