Stabilizing HIF to Ameliorate Anemia

摘要

Erythropoietin (EPO) production in the kidney is regulated by the oxygen-sensing transcription factor HIF-1 alpha, which is degraded under normoxic conditions by HIF-prolyl hydroxylase (HIF-PHD). Inhibition of HIF-PHD by roxadustat leads to increased EPO production, better iron absorption, and amelioration of anemia in chronic kidney disease (CKD).
