IGF-binding sites are found on N- and C-terminal fragments of IGFBPs, the two conserved domains of IGFBPs. (rcsb.org)
Circulating IGF-I and -II are bound to specific insulin-like growth factor (IGF)-binding proteins (IGFBPs), of which IGFBP-3 binds the majority of the IGFs. (nih.gov)
Because IGF-1 exhibits neuroprotective and myelinogenetic effects, it possesses therapeutic potential in treating neurodegenerative demyelinating diseases such as multiple sclerosis (MS). However, IGF actions are largely dependant on high-affinity regulatory IGF binding proteins (IGFBPs), which are likely to interfere with therapeutic attempts at elevating IGF-1 levels in the CNS. (vub.be)
In particular, IGFBP-2 plays a dominant role in IGF regulation in the CNS and is upregulated in several pathological conditions, including MS. The question remains as to whether IGFBPs should be considered "interfering" components of IGF treatment strategies or might possibly be utilized to clinical advantage. (vub.be)
Hepatic IGF-I circulates almost entirely bound to IGF binding proteins (IGFBPs), with less than 1% being free. (medscape.com)
The IGFBPs are a family of 6 structurally related proteins with a high affinity for binding IGF. (medscape.com)
Thus, even a small insulin-like effect of IGF-I could be more important than that of insulin itself, were it not for the IGFBPs that control the availability and activity of IGF-I. In fact, intravenous infusion of recombinant human IGF-I (rhIGF-I) can induce hypoglycemia, especially in the IGFBP3 deficient state. (medscape.com)

A severe or moderate suppression of serum insulin-like growth factor I (IGF-I) was induced in heifers, beginning at 104 days of age, by active immunization against growth hormone-releasing factor (GRFi) or by chronic feed restriction (RES), respectively. (ncsu.edu)
We hypothesized that reduced serum IGF-I results in decreased serum estradiol-17 β (E2), which in turn delays onset of puberty. (ncsu.edu)
Serum IGF-I was greater in control than in RES heifers, and was greater in both these groups than in GRFi heifers by 169 days of age. (ncsu.edu)
These data support our hypothesis that decreased serum IGF-I results in decreased serum E2. (ncsu.edu)
GRFi appears to delay puberty in heifers because decreased serum IGF-I impairs the ovary’s ability to synthesize preovulatory concentrations of E2, thereby delaying stimulation of an LH surge. (ncsu.edu)
Although her overgrowth may be a result of hyperinsulinism, her serum contains a factor (neither insulin nor IGF-1) which is able to stimulate the proliferation of lymphocyte precursors, and this could also account for the overgrowth. (bmj.com)

IGFBP-3 levels are regulated by GH and have been suggested to provide additional information on GH secretory capacity compared to IGF-I. However, the diagnostic value of IGFBP-3 is still controversial, perhaps because the quality of the available normative data for IGFBP-3 varies. (nih.gov)
Therefore, we measured IGFBP-3, IGF-I, IGF-II, IGFBP-1, and IGFBP-2 levels by RIA in 907 healthy children to establish well characterized normative data on IGFBP-3 according to age, sex, and pubertal stage and to study the complex relationship between IGFs and their BPs in puberty. (nih.gov)
Age, sex, height, BMI, and pubertal maturation were all important factors in determining the circulating levels of IGFBP-3, whereas IGF-I levels were unaffected by BMI. (nih.gov)
Comparison of IGFBP-3 with IGF-1 concentrations revealed that they did not exhibit the same developmental pattern in puberty. (nih.gov)
IGF-I levels increased to relatively higher levels than IGFBP-3, leading to an increasing molar ratio between IGF-I and IGFBP-3 in puberty, when growth velocity is high. (nih.gov)

Heritable factors explain up to 60% of the variation in IGF-I and IGFBP-3 in studies of adult twins.We systematically examined common genetic variation in 18 genes in the IGF signaling pathway for associations with circulating levels of IGF-I and IGFBP-3. (ox.ac.uk)
Multi-SNP models explained R(2) = 0.62% of the variation in circulating IGF-I and 3.9% of the variation in circulating IGFBP-3. (ox.ac.uk)
We saw no significant association between these multi-SNP predictors of circulating IGF-I or IGFBP-3 and risk of prostate or breast cancers.Common genetic variation in the IGF1 and SSTR5 genes seems to influence circulating IGF-I levels, and variation in IGFBP3 and IGFALS seems to influence circulating IGFBP-3. (ox.ac.uk)
However, these variants explain only a small percentage of the variation in circulating IGF-I and IGFBP-3 in Caucasian men and women.Further studies are needed to explore contributions from other genetic factors such as rare variants in these genes and variation outside of these genes. (ox.ac.uk)

More research is needed to fully understand the interaction between IGF-1 and the ChP, to disclose the EV-mediated signaling via the ChP, and to clarify the potential preventive effects of IGF-1 on development of IVH. (lu.se)

Allergic contact dermatitis , Multiple Sclerosis and type 1 diabetes is reduced in mice when they're given IGF-1 ( R ). (syromonoed.com)

Our findings reveal that blood-borne IGF-1 accumulates in the ChP following systemic administration of IGF-1, leading to an upregulation of genes associated with vascular maturation in the ChP. (lu.se)

In addition, expression of IGF-II and HIF-2α correlates in neuroblastoma cell lines, tumors and in sympathetic neuroblasts during embryonic week 6.5, but not later, suggesting that these IGF-II and HIF-2α expressing neuroblastomas originate from sympathetic pre-ganglia at developmental week 6.5 or earlier.

When it comes to cancer, it's probably better to err on having IGF-1 lower than higher (but not low). (syromonoed.com)
When it comes to autoimmunity or chronic inflammation , it's probably better to err on having IGF-1 higher than lower (but not high). (syromonoed.com)

Programmable DNA binding proteins have emerged as an exciting platform for engineering synthetic transcription factors for modulating endogenous gene expression 5 - 11 . (cdc.gov)

Using the novel CRISPR/Cas9-based enChIP technology in combination with SILAC-MS, we have isolated and identified potential regulatory proteins bound to the HIF2A promoter at normoxia and hypoxia. (lu.se)
