Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a hormone similar in molecular structure to insulin which plays an important role in childhood growth, and has anabolic effects in adults.
IGF-1 is a protein that in humans is encoded by the IGF1 gene. IGF-1 consists of 70 amino acids in a single chain with three intramolecular disulfide bridges. IGF-1 has a molecular weight of 7,649 Daltons. In dogs, an ancient mutation in IGF1 is the primary cause of the toy phenotype.
IGF-1 is produced primarily by the liver. Production is stimulated by growth hormone (GH). Most of IGF-1 is bound to one of 6 binding proteins (IGF-BP). IGFBP-1 is regulated by insulin. IGF-1 is produced throughout life; the highest rates of IGF-1 production occur during the pubertal growth spurt. The lowest levels occur in infancy and old age.
A synthetic analog of IGF-1, mecasermin, is used in children for the treatment of growth failure.
Tensegrity and Equilibrium: Understanding the Importance of Fascial Balance for a Healthy Body Tweet Follow @AZSPerformance Maintaining balance is essential for good health, as it enables us to move through our daily activities with ease and grace. However, balance is not just about standing upright or walking steadily - it involves a complex interplay of forces and tensions that are distributed throughout the body. One concept that can help us understand this interplay is tensegrity, which refers to a structural principle in which a system of continuous tension and compression creates a stable and flexible framework. In the context of the human body, tensegrity explains how our bones, muscles, fascia, and other tissues work together to maintain our form and function. One key aspect of tensegrity is the role of fascial tension. Fascia is a network of conn...
