Recently a family of O(2)-dependent prolyl hydroxylase domain-containing enzymes (PHD) has been identified as a cellular oxygen-sensing mechanism. Reduced prolyl hydroxylase activity initiates a signalling cascade that includes the accumulation, as well as the activation, of hypoxia-inducible factor (HIF-1alpha). In
