  1. Erythropoietin - Wikipedia

    • Red blood cell production Erythropoietin is an essential hormone for red blood cell production. Without it, definitive erythropoiesis does not take place. Under hypoxic conditions, the kidney will produce and secrete erythropoietin to increase the production of red blood cells by targeting CFU-E, proerythroblast and basophilic erythroblast subsets in the differentiation. E… 展开

    Overview

    Erythropoietin , also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted … 展开

    Pharmacology

    EPO is highly glycosylated (40% of total molecular weight), with half-life in blood around 5 h. EPO's half-life may vary between endogenous and various recombinant versions. Additional glycosylation or … 展开

    Mechanism of action

    Erythropoietin has been shown to exert its effects by binding to the erythropoietin receptor (EpoR). EPO binds to the erythropoietin receptor on the red cell progenitor surface and activates a JAK2 signalling casca… 展开

    Synthesis and regulation

    Erythropoietin levels in blood are quite low in the absence of anemia, at around 10 mU/mL. However, in hypoxic stress, EPO production may increase up to 1000-fold, reaching 10 000 mU/mL of blood. In adults, EPO is synthesiz… 展开

    Medical use

    Erythropoietins available for use as therapeutic agents are produced by recombinant DNA technology in cell culture, and include Epogen/Procrit (epoetin alfa) and Aranesp (darbepoetin alfa); they are used in treating … 展开
