Product Detail

Here is an English product overvied for IGF-1 :

1. Composition and Chemical Properties
Insulin-like Growth Factor 1 (IGF-1), also known as Somatomedin C, is a single-chain polypeptide hormone consisting of 70 amino acids with a molecular weight of approximately 7.

5 kDa . It exhibits significant structural homology with proinsulin, sharing nearly 50% amino acid sequence identity, which allows it to interact with related receptor systems . Circulating IGF-1 is primarily synthesized by the liver under the regulation of growth hormone and typically exists in a stable complex with carrier proteins (such as IGFBP-3) to prolong its half-life and maintain physiological activity .

2. Mechanism of Action
IGF-1 exerts its biological effects by binding to specific IGF-1 receptors on target cells, which activates intracellular signaling cascades including the PI3K/Akt/mTOR and Ras-MAPK pathways .

This activation stimulates protein synthesis, cell proliferation, and differentiation while simultaneously inhibiting protein breakdown and apoptosis . In metabolic regulation, it enhances glucose uptake and improves insulin sensitivity, acting through mechanisms similar to insulin but with distinct tissue-specific effects .

3. Research Advantages
Scientific investigations highlight the critical role of IGF-1 in promoting longitudinal bone growth and accelerating the regeneration of skeletal muscle and tendon tissues .

It demonstrates significant therapeutic potential in mitigating sarcopenia and frailty in aging populations by enhancing muscle mass and physical performance . Additionally, IGF-1 contributes to metabolic health by reducing insulin resistance and facilitating tissue repair processes, although its dual role in cell proliferation requires careful evaluation in clinical contexts .

4. Applicable Populations
This factor is clinically relevant for individuals with growth hormone insensitivity syndromes or severe IGF-1 deficiency, who may benefit from therapeutic replacement to support physical development .

It is also applicable to patients with osteoporosis, as it aids in bone formation and density maintenance . Furthermore, individuals experiencing age-related muscle loss or specific metabolic disorders may find IGF-1 modulation beneficial for restoring muscle function and metabolic balance .
