Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a protein that in humans is encoded by the IGF1 gene. IGF-1 has also been referred to as a "sulfation factor" and its effects were termed "nonsuppressible insulin-like activity" (NSILA) in the 1970s.
IGF-1 is a hormone similar in molecular structure to insulin. It plays an important role in childhood growth and continues to have anabolic effects in adults. A synthetic analog of IGF-1, mecasermin is used for the treatment of growth failure.
IGF-1 consists of 70 amino acids in a single chain with three intramolecular disulfide bridges. IGF-1 has a molecular weight of 17,066 daltons.

Famous quotes containing the words growth and/or factor:
“That land is like an Eagle, whose young gaze
Feeds on the noontide beam, whose golden plume
Floats moveless on the storm, and in the blaze
Of sunrise gleams when Earth is wrapped in gloom;
An epitaph of glory for the tomb
Of murdered Europe may thy fame be made,
Great People! as the sands shalt thou become;
Thy growth is swift as morn, when night must fade;
The multitudinous Earth shall sleep beneath thy shade.”
—Percy Bysshe Shelley (1792–1822)
“In his very rejection of art Walt Whitman is an artist. He tried to produce a certain effect by certain means and he succeeded.... He stands apart, and the chief value of his work is in its prophecy, not in its performance. He has begun a prelude to larger themes. He is the herald to a new era. As a man he is the precursor of a fresh type. He is a factor in the heroic and spiritual evolution of the human being. If Poetry has passed him by, Philosophy will take note of him.”
—Oscar Wilde (1854–1900)
