Introduction
IGF-1 (Insulin-like growth factor-1) is a major hormonal mediator of statural growth. Under regular circumstances, GH (growth hormone) binds to its receptor in the liver, and other tissues, and stimulates the synthesis/secretion of IGF-1. In target tissues, the Type 1 IGF receptor, that is homologous to the insulin receptor, is activated by IGF-1, leading to intracellular signaling which stimulates multiple processes leading to statural growth. IGF-1 metabolic actions are partly directed at stimulating the uptake of glucose, fatty acids, and amino acids so that metabolism supports growing tissues.

Introduction
The somatomedins, or insulin-like growth factors (IGFs), comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin' (Daughaday et al., 1972). Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B (MIM 193190) (Rotwein, 1986; Rosenfeld, 2003).

Background
IGF stands for INS like growth factors, which are proteins that have a high similarity to INS. They are part of a complicated process that uses cells to communication with the physiologic environment around them. IGF’s complex system is often called the ‘axis’. This consists of:
● Two cell-surface receptors (IGF1R and IGF2R)
● Two ligands (IGF-1 and IGF-2)
● A family of six high-affinity IGF-binding proteins.
● Proteases.
The Effect IGF Has On The Body
Many unique tissue types express the IGF-1 receptor, and the effects can vary. It induces the survival of neurons, may catalyse skeletal muscle hypertrophy by inducing protein synthesis, and by blocking muscle atrophy. It works as a protector for cartilage cells, and may work to be an anabolic factor for the bones. When used in high concentrations, it can activate the INS receptor, and can even complement the effects that INS has on the body.
Diseases And IGF
Diseases and IGF are closely related, and a number of them can be affected. The INS IGF axis is thought to have an effect on aging, with an increased life span shown in fruit flies when used in studies.
It is also important to note the crucial role that IGF plays in cancer and diabetes - IGF- 1 has been shown to stimulate growth in both prostate and breast cancer cells. The degree of risk that IGF-1 poses is up for debate, and many scientists are not in agreement. IGF has also shown to have the ability to decrease blood glucose levels, although not quite as effective as INS.
How Was IGF Discovered?
Investigators began studying the effects of biological substances on cells and tissues outside the body when IGFs were discovered. The name is self explanatory in the fact that IGF performs INS actions in some tissues, but is less potent than INS at decreasing blood sugar. Its fundamental action is to stimulate growth, whether that be within the epidermal growth factor or the nerve growth factor.
What’s The Difference Between IGF-1 And IGF-2?
The two types of IGF are IGF-1 and IGF-2. Although the names are similar, the specific actions that they take are different - they bind and activate completely difference receptors. The major actor in them both is the effect that they have on cell growth. Most of the actions of the pituitary GH are mediated by IGFs, but predominantly IGF-1. GH works to stimulate many tissues within the body, especially the liver which then secretes IGF-1. This then causes hypertrophy, or in layman's terms, an increase in cell size, as well as hyperplasia which is an increase in the number of cells.
The IGF-1 concentration will increase during childhood and hit peak during puberty, but will then decrease afterwards, as does the hormone secretion itself. It has been proven that children and adults with a deficiency of the GH have low serum IGF-1 concentrations when put in comparison with others in the same age range. Patients who have conditions like acromegaly have been shown to have increased serum IGF-1 concentrations. The production of IGF-2 is less dependent on the secretion of GH than IGF-1, and is much less important for stimulating linear growth.

Background
Insulin-like Growth Factor 1 (IGF-1) is a critical peptide hormone that plays a central role in regulating growth and development. Genetic mutations in the IGF-1 gene can result in altered IGF-1 variants, leading to various physiological consequences. Understanding these IGF-1 mutants is of paramount importance as they offer insights into growth disorders, metabolic regulation, and potential therapeutic avenues. This research delves into the world of IGF-1 mutants, shedding light on their diverse functions and implications for human health.
The primary objective of this research is to elucidate the impact of IGF-1 mutations on growth regulation. In vitro and in vivo experiments will be conducted to investigate how these mutants interact with IGF-1 receptors, influence downstream signaling pathways, and modulate growth plate dynamics. Understanding these mechanisms is crucial for unraveling the complexities of growth disorders associated with IGF-1 mutations.
The second objective is to assess the clinical relevance of IGF-1 mutants in growth-related conditions. Clinical studies involving individuals with growth hormone deficiencies or growth disorders linked to IGF-1 mutations will be conducted to evaluate the effects of these mutants on stature and overall health. These investigations may provide valuable insights into potential therapeutic strategies for individuals affected by growth-related disorders.
The third objective is to explore the broader implications of IGF-1 mutants in metabolic regulation and age-related conditions. Research will investigate their roles in metabolic homeostasis, longevity, and susceptibility to age-related diseases. Understanding the multifaceted properties of IGF-1 mutants may open new avenues for therapeutic interventions in various health and aging-related conditions.
By delving into the diverse functions of IGF-1 mutants, this research aims to expand our understanding of their physiological roles and clinical applications. The findings may contribute to the development of targeted interventions for growth disorders, metabolic conditions, and age-related diseases.

Introduction
The somatomedins, or insulin-like growth factors (IGFs), comprise a family of peptides that takes part in mammalian growth and development. IGF1 mediates various growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin' (Daughaday et al., 1972). 3 main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B (MIM 193190) (Rotwein, 1986; Rosenfeld, 2003).

More Info

Introduction
Insulin-like Growth Factor-Binding Protein 7 (IGFBP7) is a member of the IGFBP family. IGFBP family members are all cysteine rich proteins with conserved cysteine and have an IGFBP domain, a Kazal-like domain and an Ig-like C2-type domain. IGFBP7 is expressed in a broad range of normal human tissues and it mostly shows reduced expression in cancer cell lines of prostate, breast, colon, and lung origin. IGFBP7 has a role in skeletal myogenesis by binding to IGF in a manner which inhibits IGF induced differentiation of skeletal myoblasts, without disturbing IGF induced proliferation. Moreover, IGFBP7 suppresses growth and colony formation of prostate and breast cancer cell lines via an IGF independent mechanism, which triggers a delay in the G1 phase of the cell cycle, and increased apoptosis.

More Info

Introduction
Insulin-like Growth Factor-Binding Protein 7 (IGFBP7) is a member of the IGFBP family. IGFBP family members are all cysteine rich proteins with conserved cysteine and have an IGFBP domain, a Kazal-like domain and an Ig-like C2-type domain. IGFBP7 is expressed in a broad range of normal human tissues and it mostly shows reduced expression in cancer cell lines of prostate, breast, colon, and lung origin. IGFBP7 has a role in skeletal myogenesis by binding to IGF in a manner which inhibits IGF induced differentiation of skeletal myoblasts, without disturbing IGF induced proliferation. Moreover, IGFBP7 suppresses growth and colony formation of prostate and breast cancer cell lines via an IGF independent mechanism, which triggers a delay in the G1 phase of the cell cycle, and increased apoptosis.
Synonyms
Insulin-like growth factor-binding protein 7, IBP-7, IGF-binding protein 7, IGFBP-7, IGFBP-rP1, MAC25 protein, PGI2-stimulating factor, Prostacyclin-stimulating factor, Tumor-derived adhesion factor, TAF, IGFBP7, MAC25, PSF, AGM, FSTL2, RAMSVPS, IGFBP-7v, IGFBPRP1.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized IGFBP7 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGFBP-7 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized IGFBP-7 in sterile 20mM AcOH (acetic Acid) not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Background
Insulin-like growth factor-binding protein 2 (IGFBP2) is a key regulator of insulin-like growth factor (IGF) signaling pathway, playing crucial roles in cell proliferation, differentiation, and survival. IGFBP2, a member of the IGFBP family, modulates the bioavailability and activity of IGFs by binding to them and regulating their interaction with cell surface receptors. In recent years, IGFBP2 has emerged as a promising target for research due to its involvement in various physiological processes and its implications in several diseases, including cancer, metabolic disorders, and neurodegenerative conditions.
