Insulin-like growth factor binding protein-5 modulates muscle differentiation through an insulin-like growth factor-dependent mechanism
The insulin-like growth factor binding proteins (IGFBPs) are a family of six secreted proteins which bind to and modulate the actions of insulin-like growth factors-I and -II (IGF-I and -II). IGFBP-5 is more conserved than other IGFBPs characterized to date, and is expressed in adult rodent muscle and in the developing myotome. We have shown previously that C2 myoblasts secrete IGFBP-5 as their...
متن کاملInsulin-like growth factor-I regulates pro-B cell differentiation.
Progression of B-lymphocyte development in the bone marrow of postnatal mammals is marked by progressive rearrangement and expression of immunoglobulin (Ig) heavy- and light-chain genes. Following productive VHDJH gene rearrangement in the Ig heavy-chain gene complex, mu-heavy chain is the first Ig gene product expressed in cells committed to the B-lymphoid differentiation pathway. Interleukin ...
متن کاملInsulin-Like Growth Factor Binding Protein-6 Alters Skeletal Muscle Differentiation of Human Mesenchymal Stem Cells
Insulin-like growth factor binding protein-6 (IGFBP-6), the main regulator of insulin-like growth factor-2 (IGF-2), is a component of the stem cell niche in developing muscle cells. However, its role in muscle development has not been clearly defined. In this study, we investigated the role of IGFBP-6 in muscle commitment and differentiation of human mesenchymal stem cells derived from the plac...
متن کاملCoordinate expression of insulin-like growth factor II and its receptor during muscle differentiation.
The role of polypeptide growth factors in promoting muscle differentiation is uncharacterized. We have used a fusing skeletal muscle cell line, C2, to examine the endogenous expression of one peptide, insulin-like growth factor II (IGF-II), and its receptor during differentiation. The synthesis of IGF-II is low during proliferation of myoblasts; IGF-II mRNA can be detected only through use of a...
متن کاملIncreasing extraocular muscle strength with insulin-like growth factor II.
PURPOSE Botulinum toxin type A and, more recently, the immunotoxin ricin-mAb35 have been effective as means of pharmacologically weakening the extraocular muscle. However, currently there are no drug treatments to strengthen an underacting extraocular muscle. In limb muscle, treatment with insulin-like growth factor causes myofiber hypertrophy. In this study, the short-term effects of insulin-l...
