Résumé :

IGF2BP3 (also known as IMP3, KOC), a member of the insulin-like growth factor mRNA-binding protein family (IMPs), has been a research target in recent studies of promoting embryo development and exacerbating cancer. IGF2BP3 is ubiquitously expressed in early embryogenesis stages but limited in postembryonic stages, which is important in many physiological aspects such as stem cell renewal, morphological development and metabolism. A large number of studies show that IGF2BP3 interacts with many kinds of non-coding RNAs and proteins to promote cancer cell proliferation and metastasis and inhibit

Résumé :

At least a proportion of patients suffering from chronic inflammatory airway diseases respond poorly to the bronchodilator and corticosteroid therapies. There is a need for the development of improved anti-inflammatory treatment. Insulin Growth Factor 1 (IGF1) and insulin participate in not only metabolism and glucose homeostasis, but also many other physiological and pathophysiological processes, including growth and inflammation. Recently, it was shown that not only the classical IGF1 and IGF1 Receptor (IGF1R), but also the other molecules in the IGF1/insulin network, including insulin, insu

Résumé :

The insulin signaling (IIS) pathway plays an important role in the metabolism, growth, development, reproduction, and longevity of an organism. As a key member of the IIS pathway, insulin-like growth factor binding proteins (IGFBPs) are widely distributed a family in invertebrates and vertebrates that are critical in various aspects of physiology. As an important mariculture species, the growth of Pacific white shrimp, Litopenaeus vannamei, is one of the most concerning characteristics in this area of study. In this study, we identified three IGFBP genes in the genome of L. vannamei and analyz

Résumé :

Abstract IGFs are required for normal prenatal and postnatal growth. Although actions of IGFs can be modulated by a family of IGF-binding proteins (IGFBPs) in vitro, these studies have identified a complicated pattern of stimulatory and inhibitory IGFBP effects, so that understanding relevant aspects of IGFBP action in vivo has been limited. Here we have produced a null mutation of one specific IGFBP, IGFBP-4, which is coexpressed with IGF-II early in development. Surprisingly, mutation of IGFBP-4, believed from in vitro studies to be exclusively inhibitory, leads to a prenatal growth deficit

Résumé :

The insulin-like growth factor (IGF) system is a dynamic network of proteins, which includes cognate ligands, membrane receptors, ligand binding proteins and functional downstream effectors. It plays a critical role in regulating several important physiological processes including cell growth, metabolism and differentiation. Importantly, alterations in expression levels or activation of components of the IGF network are implicated in many pathological conditions including diabetes, obesity and cancer initiation and progression. In this review we will initially cover some general aspects of IGF

Résumé :

The majority of the genome is transcribed into pieces of non-(protein) coding RNA, among which long non-coding RNAs (lncRNAs) constitute a large group of particularly versatile molecules that govern basic cellular processes including transcription, splicing, RNA stability, and translation. The frequent deregulation of numerous lncRNAs in cancer is known to contribute to virtually all hallmarks of cancer. An important regulatory mechanism of lncRNAs is the post-transcriptional regulation mediated by RNA-binding proteins (RBPs). So far, however, only a small number of known cancer-associated lnc

Résumé :

Small monomeric G proteins regulated in part by GTPase-activating proteins (GAPs) are molecular switches for several aspects of vesicular transport. The yeast Gcs1 protein is a dual-specificity GAP for ADP-ribosylation factor (Arf) and Arf-like (Arl)1 G proteins, and also has GAP-independent activities. The absence of Gcs1 imposes cold sensitivity for growth and endosomal transport; here we present evidence that dysregulated Arl1 may cause these impairments. We show that gene deletions affecting the Arl1 or Ypt6 vesicle-tethering pathways prevent Arl1 activation and membrane localization, and

Résumé :

Emerging early in chordate evolution, the IGF-regulatory axis diverged from an insulin-like predecessor into a vertebrate regulatory system specializing in cell growth activation and allied anabolic functions. Essential to the divergence of the IGF and insulin systems was an early presence of soluble IGF-binding proteins (IGFBPs), which bind IGF peptides at much higher affinity than that of the insulin receptor but at comparable affinities to that of the IGF receptor. IGFBPs have no homology with IGF receptors. Instead, IGFBPs are a derived group of proteins within a superfamily of cysteine-ri

With the development of molecular techniques and transgenic and knockout mouse models, the nature, complexity, and redundancy of the IGFBPs have now started to be elucidated. Indeed the functional role of the circulating IGFs and the originally proposed endocrine somatomedin hypothesis have recently been questioned.

Résumé :

ABSTRACT Diabetes-induced growth retardation in the rodent is associated with both reduced circulating insulin-like growth factor-I (IGF-I) and enhanced levels of inhibitors of somatomedin activity. IGF-binding proteins (IGFBPs) are present in the circulation and tissue fluids and are believed to modulate the actions of IGF-I. Since elevated concentrations of the IGFBPs may contribute to the enhanced somatomedin-inhibitor activity observed in serum from diabetic animals, we have examined the amounts of hepatic IGFBP-1, -2, -3 and -4 mRNA in the spontaneously diabetic BioBreeding/Worcester rat.

Résumé :

An antiserum (R8) raised against a purified specific low-Mr (16,000-18,000) insulin-like-growth-factor (IGF)-inhibitor/binding protein, which is immunologically related to the native growth hormone (GH)-dependent Mr-150,000 IGF-binding protein in serum, has been used to probe a possible additional relationship to the predominant non-GH-dependent IGF-binding protein (Mr approximately 30,000) of human amniotic fluid. Amniotic-fluid fractions and an IGF-inhibitory fraction of serum were analysed by covalent cross-linking, ligand-blotting and immunoblotting techniques. Western blotting of the seru

Résumé :

Insulin-like growth factor binding proteins (IGFBPs) -3 and -5 are known to interact with various components of the extracellular matrix (ECM; e.g. heparin and heparan sulphate) and this interaction is believed to affect the affinity of both IGFBP species for their cognate ligands – IGF-I and -II. There is little detail on the nature of the molecular complex formed between ECM components, IGFBPs and IGFs although the glycosaminoglycan (GAG) heparin has been reported to reduce the affinity of IGFBP-5 for IGF-I. In order to investigate this phenomenon further, we have undertaken an extensive sur

Résumé :

ABSTRACT Previous studies have established that the IGFs are involved in oestrogen-induced uterine proliferation. IGF-binding proteins (IGFBPs) are present in most biological fluids and tissues and may modulate the actions of the IGFs. We examined uterine, hepatic and renal expression of the IGFBPs throughout the oestrous cycle and investigated the effects of oestradiol (OE2) on IGFBP expression in ovariectomized (ovx) rats. Uterine expression of IGFBPs-1 and -3 showed a definite variation throughout the oestrous cycle with highest levels during dioestrus. In the liver and kidney the changes i
