Recombinant human erythropoietin (rHuEPO) is a biopharmaceutical drug given to patients who have a low hemoglobin related to chronic kidney disease, cancer or anemia.
How is recombinant human erythropoietin produced?
rhEPO is produced with the use of cells transfected with either the human EPO gene or EPO cDNA (the coding sequence of the gene) linked to an expression vector (‘recombinant DNA’), which are integrated into the genome of the host cell and stably expressed over time.
What does recombinant human erythropoietin do for athletes?
Recombinant human erythropoietin (rHuEPO) has been used as a performance‐enhancing agent by athletes in a variety of sports. The resulting increase in hematocrit levels leads to increased blood viscosity and can affect blood flow, potentially increasing the athlete’s risk of developing health complications.
What is the therapeutic use of recombinant erythropoietin?
Background Human recombinant erythropoietin (rHuEPO) is widely used to stimulate red blood cell production in patients with anemia due to cancer, renal disease, and other medical conditions, but concern has grown about its overuse and potential for harm.
What is recombinant human serum albumin?
Recombinant human albumin (rHA) is a highly purified animal-, virus-, and prion-free product developed as an alternative to human serum albumin (HSA), to which it is structurally equivalent. The present investigation compared the safety, tolerability, and pharmacokinetics/pharmacodynamics of rHA with HSA.
Why do people use erythropoietin?
EPO stimulates the production of red blood cells in bone marrow and regulates the concentration of red blood cells and haemoglobin in the blood. This is useful for athletes, since red blood cells shuttle oxygen to the cells, including muscle cells, enabling them to operate more effectively.
Which type of cell is better for producing human recombinant EPO?
CHO mammalian cells
Production of rhEPO was successfully achieved in prokaryotic cells (Escherichia coli) [9], eukaryotic cells such as Pichia pastoris [10] and the standard CHO mammalian cells [11].
How does recombinant human erythropoietin repo enhance performance of endurance exercise?
The recombinant forms of erythropoietin have indiscriminately been used by athletes, mainly in endurance sports, by increasing the erythrocytes concentration, generating a better delivery of oxygen to the muscle tissue.
What is erythropoietin EPO and how is it abused by athletes?
Erythropoietin—more commonly known as EPO—is a type of blood doping that can help improve an athlete’s endurance. If EPO levels are too high the body will produce too many red blood cells which can thicken the blood, leading to clotting, heart attack and stroke. …
What is the clinical use of erythropoietin?
Erythropoietin is used in many clinical settings. The most common use is in people with anemia (low blood count) related to kidney dysfunction. When the kidneys are not properly functioning, they produce less than normal amounts of erythropoietin, which can lead to low red blood cell production, or anemia.
What is the function of erythropoietin?
Erythropoietin (Epo), which is produced by the kidney in the adult and by the liver in the fetus, increases red blood cells by supporting the survival of erythroid progenitor cells and stimulating their differentiation and proliferation via binding to Epo receptor (EpoR).
How do recombinant human erythropoietins work?
Print Share. Recombinant human erythropoietins, act like endogenous erythropoietin to stimulate erythropoiesis, the process of red blood cell production. Endogenous erythropoietin is a hormone that is secreted by particular cells in the kidneys in response to reduced levels of oxygen reaching the tissues in the kidneys.
What is erythropoietin (r-huepo)?
/eryth·ro·poi·e·tin/ (-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). recombinant human erythropoietin (r-HuEPO) epoetin.
What does erythropoiesis mean?
Also found in: Dictionary, Thesaurus, Encyclopedia. erythropoietin. 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). recombinant human erythropoietin epoetin.
What is the role of erythropoietin in brain injury?
Erythropoietin plays a neuroprotective role in response to brain injury and is antiapoptotic. Segen’s Medical Dictionary. © 2012 Farlex, Inc. All rights reserved.
