Medical term:
erythropoietin
erythropoietin
[ĕ-rith″ro-poi´ĕ-tin]a glycoprotein hormone secreted by the kidney in the adult and by the liver in the fetus, which acts on stem cells of the bone marrow to stimulate red blood cell production (erythropoiesis).

e·ryth·ro·poi·e·tin (EPO),
(ĕ-rith'rō-poy'ĕ-tin), [MIM*133170]A protein containing sialic acid that enhances erythropoiesis by stimulating formation of proerythroblasts and release of reticulocytes from bone marrow; it is formed by the kidney and liver, and possibly by other tissues, and can be detected in human plasma and urine.
Synonym(s): erythropoietic hormone (2) , hematopoietin, hemopoietin

erythropoietin
(ĭ-rĭth′rō-poi-ē′tĭn)n.
1. A glycoprotein hormone that stimulates the production of red blood cells by stem cells in bone marrow. Produced mainly by the kidneys, it is released in response to decreased levels of oxygen in body tissue.
2. Epoetin alfa.

EPO
A gene on chromosome 7q22 that encodes erythropoietin, a secreted, glycosylated cytokine found in the plasma, which regulates red cell production by promoting erythroid differentiation and initiating haemoglobin synthesis. Erythropoietin plays a neuroprotective role in response to brain injury and is antiapoptotic.Molecular pathology
Genetic variability of EPO has been linked to microvascular complications of diabetes type 2, including diabetic retinopathy, nephropathy leading to end-stage renal disease, and neuropathy

erythropoietin
EPO Physiology A 46 kD glycoprotein colony-stimulating factor produced predominantly by cells adjacent to the proximal renal tubules in response to signals from an oxygen-sensitive substances in the kidneys–eg, heme Adverse effects Chest pain, swelling, tachycardia, headache, HTN; erythropoietin–EP binds to receptors in erythroid precursors that mature into RBCs; EP is ↑ by hypoxia or by ectopic production from tumors–eg, cerebellar hemangioblastoma, hepatoma, pheochromocytoma, uterine leiomyoma, and renal cell carcinoma; it may not be ↑ in anemic premature infants, and is ↓ in 2º anemia, chronic inflammation, P vera, and certain CAs and may be useful in myeloma-related anemia; EP therapy is indicated for HIV-related anemia, anemia of renal failure and prematurity; it ↑ number of units of autologous RBCs that may be donated before surgery, for ↑ number of units that may be phlebotomized in Pts with hemochromatosis and to ↑ units that may be drawn from a person with a rare blood typeMcGraw-Hill Concise Dictionary of Modern Medicine. © 2002 by The McGraw-Hill Companies, Inc.
