Current perspectives on statins.

abstract：BACKGROUND:The hypoxia-inducible transcription factor (HIF) subunits are destabilized via the O(2)-dependent prolyl hydroxylase domain proteins (PHD1, PHD2, and PHD3). We investigated whether inhibition of PHDs via upregulating HIF might promote postischemic neovascularization. METHODS AND RESULTS:Mice with right femo...
