Erythropoietin hormone complex C016 / 4458
Erythropoietin hormone complex. Computer model showing the secondary structure of a molecule of the human hormone Erythropoietin (EPO), complexed with an erythropoetin receptor molecule. Erythropoietin regulates blood oxygen levels in the body. When levels are low (hypoxia) it is released by the kidneys and travels to the bone marrow, where it stimulates red blood cell precursor cells to mature into red blood cells (erythrocytes). This allows the blood to carry more oxygen. Because of this role it is sometimes used illegally as a performance-enhancing drug by athletes

EDITORS COMMENTS
This print showcases the intricate complexity of the Erythropoietin hormone complex, a vital component in regulating blood oxygen levels within the human body. The computer-generated model vividly depicts the secondary structure of this remarkable molecule, which is responsible for stimulating red blood cell production. Erythropoietin (EPO) plays a crucial role in maintaining our overall health by responding to low oxygen levels, known as hypoxia. When triggered by hypoxia, EPO is released by the kidneys and travels to the bone marrow where it acts as a catalyst for maturing red blood cell precursor cells into fully functional erythrocytes. This process enables our bloodstream to carry an increased amount of life-sustaining oxygen. However, despite its essential function, this glycoprotein hormone has unfortunately been exploited by some athletes seeking unfair advantages in performance enhancement. Illegally used as a doping agent due to its ability to enhance endurance and stamina, EPO has become synonymous with drug abuse within athletic circles. Through vibrant coils and ribbons representing alpha helices – key structural elements of proteins – this molecular model encapsulates both the scientific significance and controversial nature surrounding Erythropoietin. It serves as a reminder that while advancements in understanding hormones like EPO hold immense potential for medical progress and treatment of conditions such as anemia, their misuse can have detrimental consequences on fair competition within sports.
