The Epo receptor is a member of a larger family of hematopoietic growth factor receptors.
No known second messenger system has been implicated in signal transduction from the Epo receptor. Although Epo may have some effect on mitosis in early erythroid progenitor cells, its control of RBC production appears to occur in later stages of erythroid cell development, where it prevents programmed cell death. Some athletes looking for a competitive edge may seek injections of synthetic erythropoietin to increase the red blood cells and oxygen levels in their body.
However, adding more erythropoietin to a healthy body can be dangerous and increase the risk of side effects. ESA injections can help treat a number of conditions, but they do have the potential for side effects and risks. Healthy people who abuse ESA injections may be more at risk of these side effects, as the unnecessary increase of red blood cells may make the blood thicker and more prone to clotting. In some cases of use among people with cancer, the ESA may cause the tumor to grow.
Therefore, these people may only receive ESAs for a short time to help prevent the symptoms of chemotherapy. Abnormal erythropoietin levels may indicate an issue in the kidneys or bone marrow. Tests for erythropoietin levels can help doctors identify the underlying cause of blood conditions. Such causes include anemia. In people with low erythropoietin levels due to kidney disease or other conditions, ESA injections may help treat the issue.
