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...

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...

Dementia has been shown to be closely related with neuronal degeneration and/or a decrease in the activity of neural stem cells in many brain regions, including the hippocampus. It has been recently established that Neogenin is involved in the cell fate determination by regulating Oct3/4, SOX and Nanog, notable embryonic cell markers, expressions in pre-implantation mouse embryos. Further, Neogenin expression at both mRNA and protein levels is manifest in many brain regions in mice, but it remains unclear whether Neogenin expression is prerequisite for the maintenance of neural stem cells, particularly, playing a critical role in the hippocampus, a brain region known to be involved in memory generation and consolidation...

Netrin-1 is a laminin-related protein found to promote proliferation and invasion in multiple types of cancers. Recent studies have identified the function role of netrin-1 in several cancers; however, the influence of netrin-1 in human gastric cancer(GC) remains largely unknown. In this study, we found netrin-1 was upregulated in human GC tissues, where its expression correlated inversely with cancer stage and lymph node metastasis. We detected netrin-1 and its receptor knockdown significantly suppressed GC cells proliferation and invasion, while overexpression netrin-1 reversed these effects...

AIM: Recent studies have demonstrated that netrin-1 plays a vital role in bone metabolism. Previous studies have shown that osteoblasts produce netrin-1 which affects osteoclast differentiation. However, the role of netrin-1 in osteoblast differentiation is not well understood. In this study, we explored the roles of netrin-1 in osteoblasts. MATERIALS AND METHODS: Quantitative reverse-transcriptase polymerase chain reaction (qPCR), RNA interference for netrin receptors, the generation of netrin-1 plasmid, transfection of plasmids, and cell proliferation assay were performed...

Purpose: Netrin-4, a secreted protein, is found in the basement membrane of blood vessels and acts as a key regulator of angiogenesis. Here we investigated the role of Netrin-4 in the mouse-model of suture-induced corneal hem- and lymphangiogenesis. Methods: Corneal hem- and lymphangiogenesis were induced in Netrin-4-deficient (Ntn4-/-) and wild-type (WT) mice by placing three 11-0 nylon sutures intrastromally. Fourteen days after suturing, the vascularized area was analyzed via corneal flat mount immunohistochemistry...

Netrin-1 was the first axon guidance molecule to be discovered in vertebrates and has a strong chemotropic function for axonal guidance, cell migration, morphogenesis and angiogenesis. It is a secreted axon guidance cue that can trigger attraction by binding to its canonical receptors Deleted in Colorectal Cancer (DCC) and Neogenin or repulsion through binding the DCC/Uncoordinated (Unc5) A-D receptor complex. The crystal structures of Netrin-1/receptor complexes have recently been revealed. These studies have provided a structure based explanation of Netrin-1 bi-functionality...

BACKGROUND: Angiogenesis, the process in which new blood vessels are formed from preexisting ones, is highly dependent on the presence of classical angiogenic factors. Recent evidence suggests that axonal guidance proteins and their receptors can also act as angiogenic regulators. Netrin, a family of laminin-like proteins, specifically Netrin-1 and 4, act via DCC/Neogenin-1 and UNC5 class of receptors to promote or inhibit angiogenesis, depending on the physiological context. METHODS: Mesenchymal stem cells secrete a broad set of classical angiogenic factors...

Several toxins are known which account for the ability of some bacteria to initiate or promote carcinogenesis. These ideas are summarised and evidence is discussed for more specific mechanisms involving chymotrypsin and the bacterial chymotryptic enzyme subtilisin. Subtilisin and Bacillus subtilis are present in the gut and environment and both are used commercially in agriculture, livestock rearing and meat processing. The enzymes deplete cells of tumour suppressors such as deleted in colorectal cancer (DCC) and neogenin, so their potential presence in the food chain might represent an important link between diet and cancer...

The highly conserved bone morphogenetic protein (BMP) signaling pathway regulates many developmental and homeostatic processes. While the core components of the BMP pathway have been well studied, much research is needed for understanding the mechanisms involved in the precise spatiotemporal control of BMP signaling in vivo. Here, we provide evidence that two paralogous and evolutionarily conserved tetraspanins, TSP-12 and TSP-14, function redundantly to promote BMP signaling in C. elegans. We further show that the ADAM10 (a disintegrin and metalloprotease 10) ortholog SUP-17 also functions to promote BMP signaling, and that TSP-12 can bind to and promote the cell surface localization of SUP-17...

Neogenin-1 (NEO1) is a transmembrane receptor involved in axonal guidance, angiogenesis, neuronal cell migration and cell death, during both embryonic development and adult homeostasis. It has been described as a dependence receptor, because it promotes cell death in the absence of its ligands (Netrin and Repulsive Guidance Molecule (RGM) families) and cell survival when they are present. Although NEO1 and its ligands are involved in tumor progression, their precise role in tumor cell survival and migration remain unclear...

Spinal cord injury (SCI) in mammals leads to permanent loss of function because axons do not regenerate in the central nervous system (CNS). To date, treatments based on neutralizing inhibitory environmental cues, such as the myelin-associated growth inhibitors and chondroitin sulfate proteoglycans, or on adding neurotrophic factors, have had limited success in enhancing regeneration. Published studies suggested that multiple axon guidance cues (repulsive guidance molecule (RGM) family, semaphorins, ephrins, and netrins) persist in adult animals, and that their expression is upregulated after CNS injury...

BACKGROUND: The related tumour suppressor proteins Deleted in Colorectal Cancer (DCC) and neogenin are absent or weakly expressed in many cancers, whereas their insertion into cells suppresses oncogenic behaviour. Serine proteases influence the initiation and progression of cancers although the mechanisms are unknown. METHODS: The effects of environmental (bacterial subtilisin) and endogenous mammalian (chymotrypsin) serine proteases were examined on protein expression in fresh, normal tissue and human neuroblastoma and mammary adenocarcinoma lines...

Autosomal dominant polycystic kidney disease (ADPKD) is a monogenetic disease that still lacks effective therapy. Repulsive guidance molecule b (RGMb), a co-receptor for bone morphogenetic proteins (BMPs) and a ligand for neogenin, is expressed in renal tubular epithelial cells. Previous studies showed that RGMb plays negative roles in several types of tumors and prevents the immune system from over activation. The present study was designed to explore the effects of RGMb in ADPKD development. We found that expression of RGMb in kidney was less in PKD mice than wild-type mice...

Netrin-1 is a neuronal guidance cue that regulates cellular activation, migration, and cytoskeleton rearrangement in multiple cell types. It is a chemotropic protein that is expressed within tissues and elicits both attractive and repulsive migratory responses. Netrin-1 has recently been found to modulate the immune response via the inhibition of neutrophil and macrophage migration. However, the ability of Netrin-1 to interact with lymphocytes and its in-depth effects on leukocyte migration are poorly understood...

Gene silencing and overexpression techniques are instrumental for the identification of genes involved in embryonic development. Direct target gene modification in preimplantation embryos provides a means to study the underlying mechanisms of genes implicated in, for instance, cellular differentiation into the trophectoderm (TE) and the inner cell mass (ICM). Here, we describe a protocol that examines the role of neogenin as an authentic receptor for initial cell fate determination in preimplantation mouse embryos...

UNLABELLED: Neogenin, a DCC (deleted in colorectal cancer) family receptor, is highly expressed in neural stem cells (NSCs). However, its function in NSCs remains to be explored. Here we provide in vitro and in vivo evidence for neogenin's function in NSCs to promote neocortical astrogliogenesis, but not self-renewal or neural differentiation. Mechanistically, neogenin in neocortical NSCs was required for BMP2 activation of YAP (yes associated protein). The active/nuclear YAP stabilized phospho-Smad1/5/8 and was necessary for BMP2 induction of astrocytic differentiation...

Cellular interactions are key for the differentiation of distinct cell types within developing epithelia, yet the molecular mechanisms engaged in these interactions remain poorly understood. In the developing olfactory epithelium (OE), neural stem/progenitor cells give rise to odorant-detecting olfactory receptor neurons (ORNs) and glial-like sustentacular (SUS) cells. Here, we show in mice that the transmembrane receptor neogenin (NEO1) and its membrane-bound ligand RGMB control the balance of neurons and glial cells produced in the OE...
