BACKGROUND: Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-β (TGF-β) superfamily. Recently, BMP7 has been demonstrated to be produced by salivary glands and contribute to embryonic branching in mice. The BMP7 in saliva is thought to be delivered to the oral cavity and is expected to contact with stratified squamous epithelial cells which line the surface of oral mucosa. In this study, we attempted to investigate the effects of BMP7 on oral epithelial cells...

Hepatitis C virus (HCV) infection is a leading cause of hepatocellular carcinoma (HCC), mainly through cirrhosis induction, spurring research for a deeper understanding of HCV versus host interactions in cirrhosis. The present study investigated crosstalks between HCV infection and UNC5A, a netrin-1 dependence receptor that is inactivated in cancer. UNC5A and HCV parameters were monitored in patients samples (n=550) as well as in in vitro. In patients, UNC5A mRNA expression is significantly decreased in clinical HCV(+) specimens irrespective of the viral genotype, but not in (HBV)(+) liver biopsies, as compared to uninfected samples...

The precision with which neurons form connections is crucial for the normal development and function of the nervous system. The development of neuronal circuitry in the nervous system is accomplished by axon pathfinding: a process where growth cones guide axons through the embryonic environment to connect with their appropriate synaptic partners to form functional circuits. Despite intense efforts over many years to understand how this process is regulated, the complete repertoire of molecular mechanisms that govern the growth cone cytoskeleton and hence motility, remain unresolved...

A significant number of studies support the idea that inflammatory responses are intimately associated with drug-, noise- and age-related hearing loss (DRHL, NRHL and ARHL). Consequently, several clinical strategies aimed at reducing auditory dysfunction by preventing inflammation are currently under intense scrutiny. Inflammation, however, is a normal adaptive response aimed at restoring tissue functionality and homeostasis after infection, tissue injury and even stress under sterile conditions, and suppressing it could have unintended negative consequences...

BACKGROUND: Dopaminergic input to the prefrontal cortex (PFC) increases throughout adolescence and, by establishing precisely localized synapses, calibrates cognitive function. However, why and how mesocortical dopamine axon density increases across adolescence remains unknown. METHODS: We used a developmental application of axon-initiated recombination to label and track the growth of dopamine axons across adolescence in mice. We then paired this recombination with cell-specific knockdown of the netrin-1 receptor DCC to determine its role in adolescent dopamine axon growth...

Netrin-1 is an axon guidance cue and is necessary for neural and vascular development. It is involved in regulating axon guidance for attraction or repulsion, and it has a dual function in endothelial tip cell migration during angiogenesis. Netrin-1 has been shown to play an important role in angiogenesis, cancer progression, and inflammatory disease. Here we review the role of netrin-1 in retinal and angiogenesis development and the associated signaling pathways in diabetic retinopathy. The currently available data suggest that netrin-1 is a promising target for the development of anti-angiogenesis drugs...

Gliomas, a common type of brain tumor, are characterized by aggressive infiltration, making it difficultly to cure by surgery. Netrin-1, an extracellular guidance cue critical for neuronal axon path-finding, has been reported to play an important role in cell invasion and migration in several types of cancers. However, the role of netrin-1 in glioma remains largely unknown. Here, we provide evidence suggested that Netrin-1 has a critical role in glioma growth. We found that netrin-1 was significantly increased in glioma samples and positively correlated with cell proliferation, tumor grade and malignancy...

Extracellular netrin-1 and its receptor DCC promote axon branching in developing cortical neurons. Netrin-dependent morphogenesis is preceded by multimerization of DCC, activation of FAK and Src family kinases, and increases in exocytic vesicle fusion, yet how these occurrences are linked is unknown. Here we demonstrate that TRIM9-dependent ubiquitination of DCC blocks the interaction with and phosphorylation of FAK. Upon netrin-1 stimulation TRIM9 promotes DCC multimerization, but TRIM9-dependent ubiquitination of DCC is reduced, which promotes an interaction with FAK and subsequent FAK activation...

Denudation of the ependyma due to loss of cell adhesion mediated by cadherin-based adherens junctions is a common feature of perinatal hydrocephalus. Junctional stability depends on the interaction between cadherins and the actin cytoskeleton. However, the molecular mechanism responsible for recruiting the actin nucleation machinery to the ependymal junction is unknown. Here, we reveal that loss of the netrin/RGM receptor, Neogenin, leads to severe hydrocephalus. We show that Neogenin plays a critical role in actin nucleation in the ependyma by anchoring the WAVE regulatory complex (WRC) and Arp2/3 to the cadherin complex...

The axons of the DA and DB classes of motor neurons fail to reach the dorsal cord in the absence of the guidance cue UNC-6/Netrin or its receptor UNC-5 in C. elegans. However, the axonal processes usually exit their cell bodies in the ventral cord in the absence of both molecules. Strains lacking functional versions of UNC-6 or UNC-5 have a low level of DA and DB motor neuron axon outgrowth defects. We found that mutations in the genes for all six of the ENU-3 proteins function to enhance the outgrowth defects of the DA and DB axons in strains lacking either UNC-6 or UNC-5...

Human and several nonhuman species share the rare ability of modifying acoustic and/or syntactic features of sounds produced, i.e. vocal learning, which is the important neurobiological and behavioral substrate of human speech/language. This convergent trait was suggested to be associated with significant genomic convergence and best manifested at the ROBO-SLIT axon guidance pathway. Here we verified the significance of such genomic convergence and assessed its functional relevance to human speech/language using human genetic variation data...

PURPOSE OF REVIEW: To review recent advances in paraneoplastic neuropathies with emphasis on their definition, different forms and therapeutic development. RECENT FINDINGS: A strict definition of definite paraneoplastic neuropathies is necessary to avoid confusion. With carcinoma, seronegative sensory neuronopathies and neuronopathies and anti-Hu and anti-CV2/Contactin Response Mediator Protein 5 antibodies are the most frequent. With lymphomas, most neuropathies occur with monoclonal gammopathy including AL amyloidosis, Polyneuropathy-Organomegaly-Endocrinopathy-M component-Skin changes (POEMS) syndrome, type I cryoglobulinemia and antimyelin-associated glycoprotein (MAG) neuropathies and Waldenström's disease...

Axonal growth cones extend during neural development in response to precise distributions of extracellular cues. Deleted in Colorectal Cancer (DCC), a receptor for the chemotropic guidance cue netrin-1, directs F-actin reorganization and is essential for mammalian neural development. To elucidate how the extracellular distribution of netrin-1 influences the distribution of DCC and F-actin within axonal growth cones, we patterned nanoarrays of substrate bound netrin-1 using lift off nanocontact printing. The distribution of DCC and F-actin in embryonic rat cortical neuron growth cones was then imaged using total internal reflection fluorescence (TIRF) microscopy...

BACKGROUND AND PURPOSE: Netrin-1, an axon guidance protein, reduces serum levels of pro-inflammatory mediators and stabilizes the blood-brain barrier limiting the entrance of immune cells into the central nervous system. The aim was to investigate its presence in the experimental autoimmune encephalomyelitis (EAE) model and in multiple sclerosis (MS) patients with and without clinical activity. METHODS: Netrin-1 levels were evaluated in EAE mouse tissues. Afterwards, serum netrin-1 was cross-sectionally quantified in 90 patients with different MS phenotypes and 30 control subjects...

Netrins, chemotropic guidance cues, can guide the extension of serotonergic axons by binding to netrin receptors during neural development. However, little is known about whether disruption of netrin signaling is involved in the mechanisms by which organophosphorus pesticides affect serotonergic nervous system (SNS) development. In this study, we evaluated the effects of the pesticide monocrotophos (MCP) on the expression patterns of HpNetrin and its receptor neogenin as well as on the intracellular calcium ion (Ca(2+)) levels in Hemicentrotus pulcherrimus (sea urchin) by exposing fertilized embryos to 0, 0...

Platelet-rich plasma (PRP) is used to stimulate the repair of acute and chronic cartilage damage even though there is no definitive evidence of how this is achieved. Chondrocytes in injured and diseased situations frequently re-express phenotypic biomarkers of immature cartilage so tissue maturation is a potential pathway for restoration of normal structure and function. We used an in vitro model of growth factor-induced maturation to perform a comparative study in order to determine whether PRP can also induce this specific form of remodeling that is characterised by increased cellular proliferation and tissue stiffness...

The ventral midline of the embryonic neural tube, the floor plate, has a profound role in guiding axons during embryonic development. Floor plate-derived guidance cues attract or repel axons, depending on the neuronal subtype and developmental stage. Netrin-1 and its receptor, Deleted in Colon Carcinoma (DCC), are the key constituents of commissurral axons guidance cues toward the floor plate. Recent studies have implicated Down Syndrome Cell Adhesion Molecule (Dscam) as an additional Netrin-1 receptor. In this study, we examined the role of Dscam in guiding defined spinal dorsal interneuron populations...

The netrin family of proteins are involved in axon guidance during central nervous system development. In vertebrates, two membrane bound forms and five secreted forms of netrin have been reported. In addition to their critical role in neural morphogenesis, a growing number of reports suggest that netrin family proteins also play a role in inflammatory conditions, angiogenesis, and tumorigenesis. In these processes, Unc5 and DCC family proteins serve as receptors of netrin proteins. Recently, it was reported that some netrin family proteins may be involved in the pathogenesis of skeletal diseases including osteoporosis and arthritis...
