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

At least a proportion of patients suffering from chronic inflammatory airway diseases respond poorly to the bronchodilator and corticosteroid therapies.

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

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

The insulin-like growth factor (IGF) system is composed of two ligands (IGF-1 and IGF-2), two receptors (IGF-1R and IGF-2R) and six binding proteins (IGFBP-1 to -6). IGFs act as endocrine, paracrine and autocrine growth factors and stimulate cell growth, proliferation and metabolism. There is extensive evidence, both from in vitro and in vivo models as well as population studies, that IGF physiology is relevant to neoplasia. IGF-1R is the physiologic receptor for both ligands and its activation elicits a plethora of changes at the cellular level, such as activation of PI3K/AKT/mTOR and Ras/Raf

Abstract:
Duchenne muscular dystrophy (DMD) is a progressive neuromuscular disease; it occurs due to a mutation in the dystrophin protein gene; as a result, the protein is not synthesized and muscle tissue dies. On the one hand, we can say that this disease has been sufficiently studied; however, it is still incurable, and there are a number of issues remaining unclear in terms of the development of progressive dementia as a symptom in 30% of patients with Duchenne muscular dystrophy. We conducted a study at the intersection of molecular genetic, neurological, and enzyme-linked immunosorbent patients’ blood tests and experiments in organotypic culture, which allowed us to determine important points in the development of cognitive disorders in patients with Duchenne muscular dystrophy and identify a significant effect of growth factor concentration in patients. The chapter will present data on neurotrophic regulation in patients with Duchenne muscular dystrophy (by the best-studied neurotrophins), demonstrate special aspects of neuron-myocyte interaction, and broaden the understanding of the role of apoptosis and synthase proteins in the development of this disease. We would like to highlight the importance of prognostic criteria for the development of cognitive impairment and possible therapeutic measures to prevent progressive dementia

Full text
Abstract:
Background: Human studies suggest tobacco smoking is a risk factor for cognitive impairment and neurodegeneration, including Alzheimer’s disease (AD). However, experimental data linking tobacco smoke exposures to underlying mediators of neurodegeneration, including impairments in brain insulin and insulin-like growth factor (IGF) signaling in AD are lacking. Objective: This study tests the hypothesis that cigarette smoke (CS) exposures can impair brain insulin/IGF signaling and alter expression of AD-associated proteins. Methods: Adult male A/J mice were exposed to air for 8 weeks (A8), CS for 4 or 8 weeks (CS4, CS8), or CS8 followed by 2 weeks recovery (CS8+R). Gene expression was measured by qRT-PCR analysis and proteins were measured by multiplex bead-based or direct binding duplex ELISAs. Results: CS exposure effects on insulin/IGF and insulin receptor substrate (IRS) proteins and phosphorylated proteins were striking compared with the mRNA. The main consequences of CS4 or CS8 exposures were to significantly reduce insulin R, IGF-1R, IRS-1, and tyrosine phosphorylated insulin R and IGF-1R proteins. Paradoxically, these effects were even greater in the CS8+R group. In addition, relative levels of S312-IRS-1, which inhibits downstream signaling, were increased in the CS4, CS8, and CS8+R groups. Correspondingly, CS and CS8+R exposures inhibited expression of proteins and phosphoproteins required for signaling through Akt, PRAS40, and/or p70S6K, increased AβPP-Aβ, and reduced ASPH protein, which is a target of insulin/IGF-1 signaling. Conclusion: Secondhand CS exposures caused molecular and biochemical abnormalities in brain that overlap with the findings in AD, and many of these effects were sustained or worsened despite short-term CS withdrawal.
