purified, E. coli-derived recombinant human insulin-like growth factor-II.
Biochem/physiol Actions
Insulin-like growth factors -I and -II are important regulators of signaling that mediates growth and metabolism in cells. Insulin-like growth factor -II (IGF-II) is widely expressed during embryonic stages and regulates the placental development. IGF-II acts via specific receptor, IGF-IIR, the binding does not result in signal transduction, but is a mechanism to restrict the bioavailability of IGF-II. The effects of IGF-II signaling are important in growth of blood vessels (angiogenesis) gene transcription, proliferation and transformation.

Insulin-like growth factors were discovered more than 50 years ago as mediators of growth hormone that effect growth and differentiation of bone and skeletal muscle. Interest of the role of insulin-like growth factors in cancer reached a peak in the
Insulin-like growth factor II (IGF2) is perhaps the most intricately regulated of all growth factors characterized to date. Its gene is imprinted--only one allele is active, depending on parental origin--and this pattern of expression is maintained epigenetically in almost all
The last decade has been characterized by a major investigative thrust into the physiology of two unique but ubiquitous peptides, insulin-like growth factor (IGF)-I and IGF-II. The regulatory systems that control the tissue bioactivity of the IGFs have been delineated

Insulin and insulin-like growth factors (IGFs) are important regulators of energy metabolism and growth. Several findings have outlined an important role played by this family of molecules in both tumor maintenance and development. Despite the established contribution of the IGF
