somatomedin

 [so″mah-to-me´din]
any of a group of peptides found in the liver and in other tissues which mediate the effect of growth hormone (somatotropin) on cartilage; they are responsible for uptake of sulfate and increased synthesis of collagen and other proteins by cartilage. Somatomedins also have insulinlike biologic actions and increase RNA synthesis and promote DNA synthesis.

so·ma·to·me·din

(sō'mă-tō-mē'din),
One of several peptides; somatomedin peptide (MW about 4,000), also called insulinlike growth factor II, is synthesized in the liver and probably in the kidney; it is capable of stimulating certain anabolic processes in bone and cartilage, such as synthesis of DNA, RNA, and protein (including chondromucoprotein), and the sulfation of mucopolysaccharides; secretion and biologic activity of somatomedin is known to depend on somatotropin.
See also: insulinlike growth factor.

Serum somatomedin C/IGF-I and IGFBP-3 were determined in duplicate by using a DSL ACTIVE IGF-I and IGFBP-3 immunoradiometric assay (IRMA) kit (Diagnostic System Laboratories, Webster, Texas).
Therefore, our results might most likely reflect the training-induced effect of somatomedin and hormones on cardiac cells.
These proteins were initially called somatomedins because of their growth-promoting properties in numerous tissues and the inability to suppress their bioactivity with anti-insulin antibodies (2, 4).
Cultured fibroblast monolayers secrete a protein that alters the cellular binding of somatomedin C/IGF I.
The liver has received special attention for the past several decades as a major source of circulating IGF since Salmon and Daughaday (1957) published the somatomedin hypothesis which states that the growth-stimulating action of GH on skeletal tissue is elicited indirectly by "sulfation factor" now known as IGF secreted upon stimulus of GH mostly likely from the liver.
