Correct Answer
C. It is stimulated when a patients has an oxygen saturation of 95%Explanation
EPO is a glycoprotein hormone that controls erythropoiesis, or red blood cell production. It is a cytokine for erythrocyte (red blood cell) precursors in the bone marrow. Also called hematopoietin or hemopoietin, it is produced by the liver and kidney, and is the hormone that regulates red blood cell production.
Regulation is believed to rely on a feed-back mechanism measuring blood oxygenation. Constitutively synthesized transcription factors for EPO, known as hypoxia inducible factors (HIFs), are hydroxylated and proteosomally digested in the presence of oxygen. (95% O2 Sat= hypoxia)Rate this question:
