A synthetic analog of IGF-1, mecasermin, is used for the treatment of growth failure in children with severe IGF-1 deficiency. [15] Cyclic glycine-proline (cGP) is a metabolite of hormone insulin-like growth factor-1 (IGF-1).
They are relatively small-sized crocodilians with an average maximum weight of 6 to 40 kg (13 to 88 lb) depending on species, with the exception of the black caiman (Melanosuchus niger), which can grow more than 4 m (13 ft) in length and weigh in excess of 450 kg (1,000 Ib). The black caiman is the largest caiman species in the world and is ...
Insulin-like growth factor 2 (IGF-2, at times IGF-II) is thought to be a primary growth factor required for early development while IGF-1 expression is required for achieving maximal growth. Gene knockout studies in mice have confirmed this, though other animals are likely to regulate the expression of these genes in distinct ways.
Insulin-like growth factor-1 (IGF-1) Insulin-like growth factor-2 (IGF-2) Interleukins IL-1- Cofactor for IL-3 and IL-6. Activates T cells. IL-2 – T-cell growth factor. Stimulates IL-1 synthesis. Activates B-cells and NK cells. IL-3 – Stimulates production of all non-lymphoid cells. IL-4 – Growth factor for activated B cells, resting T ...
The insulin-like growth factor 1 (IGF-1) receptor is a protein found on the surface of human cells. It is a transmembrane receptor that is activated by a hormone called insulin-like growth factor 1 and by a related hormone called IGF-2. It belongs to the large class of tyrosine kinase receptors. This receptor mediates the effects of IGF-1 ...
Females generally grow to no more than 1.08 to 1.4 m (3 ft 7 in to 4 ft 7 in) (the lower size typical upon the onset of sexual maturity), but can rarely grow to nearly 2 m (6 ft 7 in). Adult males can regularly reach 1.5 to 1.8 m (4 ft 11 in to 5 ft 11 in) while large mature ones grow to 2.0 to 2.5 m (6 ft 7 in to 8 ft 2 in), although ...
IGFBP-3, the most abundant protein, accounts for 80% of all IGF binding. IGF-1 binds to IGFBP-3 in a 1:1 molar ratio. IGF-BP also binds to IGF-1 inside the liver, allowing growth hormone to continuously act upon the liver to produce more IGF-1. IGF binding proteins (IGFBPs) are proteins of 24 to 45 kDa. All six IGFBPs share 50% homology with ...
Most adult black caimans are 2.2 to 4.3 m (7 ft 3 in to 14 ft 1 in) in length, with a few old males exceeding 5 m (16 ft 5 in). Sub-adult male specimens of around 2.5 to 3.4 m (8 ft 2 in to 11 ft 2 in) will weigh roughly 95 to 125 kg (209 to 276 lb), around the same size as a mature female, but will quickly increase in bulk and weight.
