Erythropoietin molecule bound to receptor
Erythropoietin molecule bound to receptors. Computer model of a molecule of erythropoietin (EPO) (orange) bound to two extracellular EPO receptors (pink and purple). EPO is a glycoprotein that is produced by the kidneys in response to low blood oxygen levels. It stimulates the erythrocyte (red blood cell) precursor cells in the bone marrow to mature into erythrocytes. It is used therapeutically to treat anaemia caused by renal failure or chemotherapy. It is also abused by athletes who use it to enhance their performance by increasing blood oxygen levels. However, this use also causes thickening of the blood which can lead to death

EDITORS COMMENTS
This image captures the intricate structure of an erythropoietin molecule bound to its receptors. The computer-generated model showcases the orange-colored erythropoietin molecule, which is a glycoprotein produced by the kidneys in response to low blood oxygen levels. Its primary function is to stimulate the maturation of red blood cell precursor cells in the bone marrow, ultimately leading to an increased production of red blood cells. While this molecule holds significant therapeutic value for treating anaemia caused by renal failure or chemotherapy, it unfortunately also finds illicit use among athletes seeking performance enhancement. By increasing blood oxygen levels, athletes hope to gain a competitive edge; however, this misuse can have severe consequences such as thickening of the blood and even death. The pink and purple structures depicted in this artwork represent two extracellular erythropoietin receptors that bind with the EPO molecules. These receptors play a crucial role in transmitting signals within our body's cellular machinery. Overall, this visually striking illustration provides us with a glimpse into both the scientific and controversial aspects surrounding erythropoietin. It serves as a reminder of how complex biological compounds like these can be harnessed for medical advancements but also exploited for unethical purposes such as doping in athletics.
