Abstract (sommario):

Background: The vegan diet in children provides the benefit of reducing the risk of being overweight and improving the fat profile. The risk that can occur in the provision of a vegan diet in children is anthropometric size below reference and low caloric intake. Growth hormone (GH) and Insulin like Growth Factors (IGFs) are powerful stimulators for longitudinal growth of bone and require insulin-like growth factor binding protein (IGFBPs) which acts as a transport protein for IGF-1. A vegan diet with lower calorie intake in children has lower IGF-I levels than children with an omnivorous diet.Objective: Examining the effect of vegan diets on IGF-1 levels, IGFBP-3 levels, and growth velocity.Methods: This study was done with a prospective cohort design. The study subjects were divided into two groups, namely the vegan group and the omnivorous group, then matched based on age and sex. During the study, anthropometric data collection, IGF-1 and IGFBP-3 levels measurements were done in both vegan children and omnivorous children.Results: During 6 months of observation, 22 subjects were divided into two groups, namely children with a vegan diet and children with an omnivorous diet. IGF-1 (ng / mL) in vegan children was 105.5 ± 47.3 compared to 102.7 ± 42.3 in omnivorous children with a value of p = 0.89. IGFBP-3 (ng / mL) in vegan children was 2146.4 ± 595.1 compared to 2142 ± 609.1 in omnivorous children with value of p = 0.99 and Growth Velocity (cm / 6 months) was 3.0 in vegan children (1.0-5.30), and 3.2 (2.6-6.5) in omnivorous children with value of p = 0.41.Conclusion:Children with vegan diet had IGF-1 level, IGFBP-3 level, and growth velocity that were the same as children with an omnivorous diet.

Abstract (sommario):

Insulin-like growth factor (IGF-I, IGF-II) action is influenced by until today known eight forms of insulin-like growth factor binding proteins (IGFBPs). They have been obtained not only from some human and animal tissues and body fluids but also from conditioned medium of cell cultures. An important biological property of the IGFBPs is their ability to increase the circulating half-life of the IGFs. They are able to act as potentiators of cell proliferation. As IGFBPs bind to cell surfaces, they may act either to deliver the IGFs to those surfaces for activation of specific receptors or to activate cell responses independently of receptor activation. Phosphorylation, glycosylation and proteolysis of IGFBPs influence their affinity to IGFs. The IGFBPs in the role of inhibitors may block the activity of the IGFs and be used for antimitogenic therapy. In the last time measuring of IGFBPs levels can be used for diagnosis determination of some endocrine diseases or in differential diagnostics.

Abstract (sommario):

We report the localization of insulin-like growth factor I (IGF-I) and a 25-kDa form of insulin-like growth factor-binding protein (IGF-BP-1) in adult rat kidney. The antigens were localized using a rabbit anti-human IGF-I antibody, and a rabbit anti-human IGF-BP-1 antibody raised against human 25-kDa IGF-BP-1 purified from amniotic fluid. Immunohistochemistry by the avidin-biotin peroxidase conjugate technique showed that both peptides are located in the same nephron segments, in the same cell types. The most intense staining was in papillary collecting ducts. There was moderate staining also in cortical collecting ducts and medullary thick ascending limbs of Henle's loop. In collecting ducts the antigens were shown to be present in principal cells but not in intercalated cells. In distal convoluted tubules, cortical thick ascending limbs, and in structures presumptively identified as thin limbs of Henle's loops there was only modest staining. The macula densa, however, lacked immunoreactivity. Colocalization of IGF-I and IGF-BP-1 in the same cells supports the notion, derived from studies on cultured cells, that the actions of IGF-I may be modified by IGF-BPs that are present in the same location.

Abstract (sommario):

Abstract. Insulin-like growth factor II and insulin-like growth factor binding protein-1 were identified and quantified in the urine of 23 healthy subjects between 17 and 76 years of age. IGF-II was measured after separation by gel chromatography at low pH and compared with IGF-I levels in the same samples, whereas IGF binding protein-1 was measured in dialysed urine. Urinary IGF-II was found at much higher concentrations than IGF-I (mean ±sem: 717±69 vs 110±5 ng/mmol creatinine). The chromatographic profile indicates that pro-IGF-II may also be present. The concentrations of IGF-II appear to be less variable than the other reported parameters. The mean IGF binding protein-1 concentrations in these urine samples was 414±83 ng/mmol creatinine. IGFs in the urine are in part bound to binding proteins.

Abstract (sommario):

Insulin-like growth factors (IGFs) I and II are considered to be autocrine regulators of bone cell function. Recently, we demonstrated that IGF-I induces IGF-binding protein-5 (IGFBP-5) expression in cultures of osteoblast-enriched cells from 22-day fetal rat calvariae (Ob cells). In the present study, we postulated that IGFs play an autocrine role in the maintenance of IGFBP-5 basal expression in Ob cells. IGFBP-2 and -3, at concentrations that bind endogenous IGFs, decreased IGFBP-5 mRNA levels, as determined by Northern blot analysis, and protein levels, as determined by Western immunoblots of extracellular matrix extracts of Ob cells. IGFBP-2 and -3 in excess inhibited IGFBP-5 heterogeneous nuclear RNA levels, as determined by RT-PCR, and did not alter the half-life of IGFBP-5 mRNA in transcriptionally arrested Ob cells. In conclusion, blocking endogenous IGFs in Ob cells represses IGFBP-5 expression, suggesting that IGFs are autocrine inducers of IGFBP-5 synthesis in osteoblasts.

Abstract (sommario):

Insulin-like growth factor (IGF)-I and its binding protein IGF binding protein 5 (IGFBP-5) were highly expressed in inflamed and fibrotic intestine in experimental Crohn's disease. IGF-I induced proliferation and increased collagen synthesis by smooth muscle cells and fibroblasts/myofibroblasts in vitro. Here we studied IGF-I and IGFBP-5 in Crohn's disease tissue. Tissue was collected from patients undergoing intestinal resection for Crohn's disease. IGF-I and IGFBP-5 mRNAs were quantitated by RNase protection assay and Northern blot analysis, respectively. In situ hybridization was performed to localize mRNA expression, and Western immunoblot was performed to quantitate protein expression. IGF-I and IGFBP-5 mRNAs were increased in inflamed/fibrotic intestine compared with normal-appearing intestine. IGF-I mRNA was expressed in multiple cell types in the lamina propria and fibroblast-like cells of the submucosa and muscularis externa. IGFBP-5 mRNA was highly expressed in smooth muscle of the muscularis mucosae and muscularis externa as well as fibroblast-like cells throughout the bowel wall. Tissue IGFBP-5 protein correlated with collagen type I ( r = 0.82). These findings are consistent with a mechanism whereby IGF-I acts on smooth muscle and fibroblasts/myofibroblasts to increase collagen synthesis and cellular proliferation; its effects may be modulated by locally expressed IGFBP-5.

Abstract (sommario):

Insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) possesses both growth-inhibitory and -potentiating effects on cells that are independent of IGF action and are mediated through specific IGFBP-3 binding proteins/receptors located at the cell membrane, cytosol, or nuclear compartments and in the extracellular matrix. We have here characterized transferrin (Tf) as one of these IGFBP-3 binding proteins. Human serum was fractionated over an IGFBP-3 affinity column, and a 70-kDa protein was eluted, sequenced, and identified (through database searching and Western immunoblot) as human Tf. Tf bound IGFBP-3 but had negligible affinity to the other five IGFBPs, and iron-saturated holo-Tf bound IGFBP-3 more avidly than unsaturated Tf. Biosensor interaction analysis confirmed that this interaction is specific and sensitive, with a high association rate similar to IGF-I, and suggested that binding occurs in the vicinity of the IGFBP-3 nuclear localization site. As an independent confirmation of this interaction, using a yeast two-hybrid system, we cloned Tf from a human liver complementary DNA library as an IGFBP-3 protein partner. Tf treatment blocked IGFBP-3-induced cell proliferation in bladder smooth muscle cells, and IGFBP-3-induced apoptosis in prostate cancer cells. In summary, we have employed a combination of techniques to demonstrate that Tf specifically binds IGFBP-3, and we showed that this interaction has important physiological effects on cellular events.

Abstract (sommario):

RNA-binding proteins have been associated with cancer development. The overexpression of a well-known RNA-binding protein, insulin-like growth factor 2 messenger RNA–binding protein 3, has been identified as an indicator of poor prognosis in patients with various types of cancer. Although gastric cancer is a relatively frequent and potentially fatal malignancy, the mechanism by which insulin-like growth factor 2 messenger RNA–binding protein 3 regulates the development of this cancer remains unclear. This study aimed to investigate the role and regulatory mechanism of insulin-like growth factor 2 messenger RNA–binding protein 3 in gastric cancer. An analysis of IGF2BP3 expression patterns reported in 4 public gastric cancer–related microarray data sets from the Gene Expression Omnibus and The Cancer Genome Atlas-Stomach Adenocarcinoma revealed strong expression of this gene in gastric cancer tissues. Insulin-like growth factor 2 messenger RNA–binding protein 3 expression in gastric cancer was further confirmed via quantitative reverse transcription polymerase chain reaction and immunohistochemistry, respectively, in an in-house gastric cancer cohort (n = 30), and the association of insulin-like growth factor 2 messenger RNA–binding protein 3 expression with clinical parameters and prognosis was analyzed. Notably, stronger IGF2BP3 expression significantly correlated with poor prognosis, and significant changes in insulin-like growth factor 2 messenger RNA–binding protein 3 expression were only confirmed in patients with advanced-stage gastric cancer in an independent cohort. The effects of insulin-like growth factor 2 messenger RNA–binding protein 3 on cell proliferation were confirmed through in vitro experiments involving the HGC-27 gastric cancer cell line. MicroR-125a-5p, a candidate microRNA that target on insulin-like growth factor 2 messenger RNA–binding protein 3, decreased in advanced-stage gastric cancer. Upregulation of microR-125a-5p inhibited insulin-like growth factor 2 messenger RNA–binding protein 3, and dual-luciferase report assay indicated that microR-125a-5p inhibited the translation of IGF2BP3 by directly targeting the 3′ untranslated region. These results indicate that the microR-125a-5p/insulin-like growth factor 2 messenger RNA–binding protein 3 axis contributes to the oncogenesis of advanced gastric cancer.

Abstract (sommario):

Abstract Accurate measurement of insulin-like growth factor (IGF) binding protein-1 (IGFBP-1) is important for precise definition of its physiological roles and potential diagnostic values. Because altered phosphorylation results in altered IGFBP-1 immunoreactivity, current assays may significantly underestimate or fail to detect physiological changes in the IGFBP-1 concentrations. We developed three ELISAs (ELISA 1–3) using a common capture but three different detection antibodies. IGFBP-1 in serum, synovial fluid (SF), cerebrospinal fluid (CSF), and amniotic fluid (AF) were measured before and after treatment with alkaline phosphatase (ALP). Among the methods, only ELISA-1 was unaffected by IGFBP-1 phosphorylation and generated identical results before and after ALP treatment. The serum and SF values by ELISA-2 and -3 were lower by ∼4- to 10-fold, but increased after ALP treatment to within 66–98% of those by ELISA-1. The medians in AF, and to a lesser extent in CSF, by all methods were similar and did not change significantly after dephosphorylation. ELISA-1 showed excellent correlation with ELISA-2, ELISA-3, and a commercial IGFBP-1 IRMA only after ALP-treated samples were analyzed by the comparative methods. ELISA-1 is highly specific for IGFBP-1 and demonstrated acceptable analytical performance characteristics.

Abstract (sommario):

The IGF (insulin-like growth factor) system is essential for physiological growth and it is also implicated in a number of diseases including cancer. IGF activity is modulated by a family of high-affinity IGF-binding proteins, and IGFBP-6 is distinctive because of its marked binding preference for IGF-II over IGF-I. A principal role for IGFBP-6 is inhibition of IGF-II actions, but recent studies have indicated that IGFBP-6 also has IGF-independent effects, including inhibition of angiogenesis and promotion of cancer cell migration. The present review briefly summarizes the IGF system in physiology and disease before focusing on recent studies on the regulation and actions of IGFBP-6, and its potential roles in cancer cells. Given the widespread interest in IGF inhibition in cancer therapeutics, increasing our understanding of the mechanisms underlying the actions of the IGF ligands, receptors and binding proteins, including IGFBP-6, will enhance our ability to develop optimal treatments that can be targeted to the most appropriate patients.

Abstract (sommario):

Growth hormone (GH) secretory alterations and dysregulations with insulin-like growth factor-I (IGF-1) axis among type-1 diabetic children and adolescents is well established. In this poorly controlled abnormal metabolic state, GH hypersecretion is observed with decreased levels of Insulin-like Growth Factors (IGFs), IGF binding proteins-3 (IGFBP-3), and growth hormone binding protein (GHBP). These all factors results in decreased growth velocity and growth retardation in type-1 diabetic children and adolescents. Insulin is the most important metabolic regulator of this system. Absolute insulin deficiency, as observed in type-1 diabetics, is the primary cause of this dysregulation and alterations. Several published studies have shown that elevated HbA1c and poor glycaemic control are the main factors of this abnormal metabolic state. Conversely, studies have also demonstrated that good glycaemic control with basal bolus insulin regimens or insulin pump can improve diabetic state with restoration of normal growth. Hence this perspective review focuses on these important aspects of growth abnormalities in type-1 diabetic patients and concludes that health care policy makers should develop a close monitoring program and system with multi-disciplinary team approach to prevent further diabetes related growth complications.

Abstract (sommario):

Abstract The last decade has been characterized by a major investigative thrust into the physiology of two unique but ubiquitous peptides, insulin-like growth factor (IGF)-I and IGF-II. The regulatory systems that control the tissue bioactivity of the IGFs have been delineated, and subcellular signaling mechanisms have been clarified. Clearly, both tissue and circulating growth factor concentrations are important in defining the relationship between IGF-I and cell activity. Bone, liver, and circulatory IGF-I have received the most attention by investigators, in part because of the ease of measurement and the interaction with disease states such as osteoporosis. More recently, attention has focused on the role IGF-I plays in neoplastic transformation and growth. Two large prospective observational studies have demonstrated greater risk for prostate and breast cancer associated with high circulating concentrations of IGF-I. Animal models and in vitro studies confirm that there is a close, albeit complex, interaction between IGF-I signaling and bone turnover. This report will focus on: (a) IGF physiology, including IGF ligands, binding proteins, and proteases; (b) the relationship between IGF-I and bone mass in respect to risk for osteoporosis; (c) the heritable regulation of the IGF-I phenotype; and (d) the association between serum IGF-I and cancer risk. The IGFs remain a major area for basic and clinical investigations; future studies may define both diagnostic and therapeutic roles for these peptides or their related proteins in several disease states.

Roelen CA, Koppeschaar HP, de Vries WR, Zelissen PM, Snel YE, Doerga ME, Thijssen JH, Blankenstein RA. High-affinity growth hormone binding protein, insulin-like growth factor I and insulin-like growth factor binding protein 3 in adults with growth hormone deficiency. Eur J Endocrinol 1996;135:82–6. ISSN 0804–4643 The high-affinity growth hormone binding protein (GHBP) circulates in human blood and represents the extracellular domain of the growth hormone (GH) receptor. The effects of GH deficiency on GHBP in adults are not clear. The aim of this study was to evaluate serum GHBP levels in adults with GH deficiency and to assess whether GHBP measurement may contribute to the diagnosis of adult GH deficiency, based on a two-step model. We measured insulin-like growth factor I (IGF-I), IGF binding protein 3 (IGFBP-3) and GHBP levels in serum samples of 36 patients with adult-onset GH deficiency. The GHBP levels were measured by FPLC size-exclusion chromatography; IGF-I and IGFBP-3 levels were measured by RIA. Serum GHBP levels were elevated above the upper limit of the 95% confidence interval in 26 patients, whereas IGF-I and IGFBP-3 levels were low in 10 patients and in 16 patients, respectively. The combination of low serum IGF-I and low IGFBP-3 levels was found in 10 patients. In nine patients, serum IGF-I levels were low, with elevated GHBP levels. Low serum IGF-I, low IGFBP-3 and elevated GHBP levels were found in five patients. Only four out of 36 patients had serum IGF-I, IGFBP-3 and GHBP levels that were within the 95% confidence interval of the control values. We conclude that adults with acquired GH deficiency have elevated GHBP levels in comparison to healthy subjects. We suggest that measurement of GHBP levels might contribute to the diagnosis of adult GH deficiency, though further research is required to study the additional value of GHBP measurements.
