Using an unbiased proteomic strategy, we previously identified neurofibromin as a candidate partner of recombinant 5-HT6 receptor expressed in HEK-293 cells (12). In line with the common influence of 5-HT6 receptor and neurofibromin in brain development, learning and memory, and brain cAMP signaling (23, 24), we further characterized in this study 5-HT6 receptor-neurofibromin interaction and showed that they form a complex in mouse brain. Moreover, we showed that 5-HT6 receptor-neurofibromin interaction is a dynamic process that depends on receptor conformational state and can be prevented by a specific antagonist (SB271046), which thus behaves as an inverse agonist to disrupt this spontaneous (constitutive) association. Using BRET, we provided evidence that the PH domain and the CTD of neurofibromin independently interact with the receptor, suggesting that they contribute to the association of the receptor with full-length neurofibromin. Nonetheless, the higher affinity of PH domain for the ...

Abstract. The neurofibromin 1 gene (NF1), located at 17q11.2, encodes the RAS GTPase activating protein neurofibromin. Somatic mutations of NF1 are commonly fo

Neurofibromin is a tumor suppressor protein encoded by the Nf1 gene on human chromosome 17. Neurofibromin helps protect cells against cancer by suppressing Ras, a potent activator of cell growth and proliferation. People with mutations in the Nf1 gene develop neurofibromatosis type I (NF1), a neurological disorder that affects 1 in 3,500 people world-wide. NF1 patients develop benign tumors along their peripheral and optic nerves, as well as café-au-lait skin spots. NF1 is also associated with an increased risk of malignant neurological tumor development and childhood learning disabilities ...

In a cell with no KRAS mutations, a known tumor suppressor called neurofibromin keeps healthy KRAS proteins well-behaved. But most KRAS mutations are overly active and cannot be controlled by neurofibromin. When mutated KRAS is present, neurofibromin attempts to control the mutant KRAS at the expense of controlling the healthy KRAS. So why is the KRAS G13D mutation any different? Why does it respond to Cetuximab? The scientists discovered that even though KRAS G13D is overly active, it is doing so without neurofibromin being aware. Thus, neurofibromin can still keep the healthy KRAS under control. Additionally, the researchers demonstrated that cetuximab will only work to suppress tumors as long as there is neurofibromin available to suppress the activity of healthy KRAS. This work demonstrates the power of computational systems biology approaches to address problems in personalized medicine, says Stites. Doctors could sequence the gene to find out if the patient has this KRAS G13D variant, ...

Neurofibromatosis type 1 (NF1) is a rare genetic disorder seen in one of every 3,000 to 4,000 people worldwide. The autosomal dominant condition, which affects half of a patients children, is characterized by changes in skin coloring, or pigmentation, and the growth of tumors along nerves. These tumors are most commonly seen on the skin and can present anywhere there is a peripheral nerve.. The NF1 gene provides instructions for making a protein termed neurofibromin. The protein is produced in many cells, including nerve cells and the specialized cells surrounding nerves, which are called oligodendrocytes in the brain and spinal cord, and Schwann cells in peripheral nerves.. Neurofibromin is a tumor suppressor, preventing cells from growing and dividing too rapidly or in an uncontrolled manner. Mutations in this gene lead to the production of a nonfunctional version of neurofibromin that cannot regulate cell growth and division. Therefore, tumors such as neurofibromas can form along nerves ...

Ras proteins are guanine-nucleotide binding proteins that have a low intrinsic GTPase activity that is enhanced 10(5)-fold by the GTPase-activating proteins (GAPs) p120-GAP and neurofibromin. Comparison of the primary sequences of RasGAPs shows two invariant arginine residues (Arg1276 and Arg1391 of neurofibromin). In this study, site-directed mutagenesis was used to change each of these residues in the catalytic domain of neurofibromin (NF1-334) to alanine. The ability of the mutant proteins to bind to Ras.GTP and to stimulate their intrinsic GTPase rate was then determined by kinetic methods under single turnover conditions using a fluorescent analogue of GTP. The separate contributions of each of these residues to catalysis and binding affinity to Ras were measured. Both the R1276A and the R1391A mutant NF1-334 proteins were 1000-fold less active than wild-type NF1-334 in activating the GTPase when measured at saturating concentrations. In contrast, there was only a minor effect of either ...

Melanocytic iris hamartomas, sometimes called Lisch nodules, are considered pathognomonic of this disease but are found in only about 75% of patients. These appear as sharply defined, smooth masses on the stromal surface and consist of spindle cells of melanocytic origin. Their presence correlates with the severity of skin freckles and cafe-au-lait spots. Also characteristic of neurofibromatosis 1 are eyelid fibromas causing ptosis and the familiar horizontal S-sign in the upper lid margin but these are only found in one-third of patients. Ciliary body cysts have been reported to occur at a frequency of 78%, or 10 times more frequently than in unaffected individuals. Nearly half of patients have occludable anterior chamber angles (Types 1 and 2).. Gliomas of the optic nerves, chiasm or optic tracts are slow growing astrocytomas that occur in about 15% of children at a mean age of about 5 years. While these comprise the most common intracranial tumors in NF1, they typically have a benign course ...

Neurofibromatosis type I (NF1) is one of the most common single-gene disorders that causes learning deficits in humans. Mice carrying a heterozygous null mutation of the Nfl gene (Nfl(+/-) show important features of the learning deficits associated with NF1 (ref. 2). Although neurofibromin has several known properties and functions, including Ras GTPase-activating protein activity, adenylyl cyclase modulation and microtubule binding, it is unclear which of these are essential for learning in mice and humans. Here we show that the learning deficits of Nf1(+/-) mice can be rescued by genetic and pharmacological manipulations that decrease Ras function. We also show that the Nf1(+/-) mice have increased GABA (gamma-amino butyric acid)-mediated inhibition and specific deficits in long-term potentiation, both of which can be reversed by decreasing Ras function. Our results indicate that the learning deficits associated with NF1 may be caused by excessive Ras activity, which leads to impairments in ...

The only gene known to be associated with Legius syndrome is SPRED1. It is located on chromosome 15q13.2, has seven coding exons and it encodes for Spred-1 (Sprouty Related Evh1 Domain-containig protein1), a protein of 444-amino acid. This protein comprises an N-terminal EVH-1 domain, a central KIT binding domain and a cysteine rich C-terminal SPRY domain.. RAS/MAPK pathway is essential for the maintenance of cellular homeostasis. RAS proteins, present in three isoforms HRAS, NRAS, KRAS, are monomeric membrane GTPase involved in cellular growth, differentiation, apoptosis. The active complex RAS-GTP leads to the activation of RAF, a serine- threonine kinase, which phosphorylates the MAPK MEK1 and MEK2 activating them. MAPK in turn phosphorylate and activate ERK1 and ERK2. They are the ultimate effectors and exert their function on a large number of downstream molecules, both nuclear and cytosolic. ERK1 and ERK2 substrates include nuclear components, transcription factors, membrane proteins and ...

Numerous studies have shown that active p21ras-GTP can bind to multiple isoforms of the p110 catalytic subunits of type IA PI-3K to specifically augment kinase activity (18)(19)(20). However, in neurofibromin-deficient cells, most attention has been focused on modulation of the classical p21ras-Raf-Mek-ERK pathway to augment cellular proliferation. In primary mast cells, activation of PI-3K after c-kit binding to SCF is critical for controlling proliferation (15)(33). Our study shows that Nf1+/− mast cells have a twofold increase in proliferation in response to SCF compared with wild-type cells, and proliferation was completely reduced with PI-3K inhibitors, confirming the importance of PI-3K activation to the Nf1+/− cellular phenotype. Importantly, placement of cutaneous microosmotic pumps which released a continuous infusion of SCF resulted in a greater accumulation of mast cells at the site of insertion in Nf1+/− mice compared with wild-type mice. Others have previously shown that in ...

CMT is the most common genetic disorder affecting the nervous system and there is currently no cure. More than 20,000 people in the UK suffer from the disease, which typically causes progressive weakness and long-term pain in the feet, leading to walking difficulties.. Research conducted by Dr Andrew Grierson and his team has revealed that zebrafish could hold the key to finding new therapeutic approaches to treat the condition.. Dr Grierson, from the Universitys Department of Neuroscience, said: We have studied zebrafish with a genetic defect that causes CMT in humans. The fish develop normally, but once they reach adulthood they start to develop difficulties swimming.. By looking at the muscles of these fish we have discovered that the problem lies with the connections between motor neurons and muscle, which are known to be essential for walking in humans and also swimming in fish.. He added: Motor neurons are the largest cells in our bodies, and as such they are highly dependent on a ...

NF1 is thought to cause disease by following characteristics of the two-hit hypothesis, first described by Alfred Knudson in 1971. All patients with NF1 are heterozygous for the NF1 mutation, and it is thought that somatic mutations lead to the development of tumors by causing a loss of heterozygosity.11 The mutation most often results in truncation of neurofibromin, though ,500 types of mutations have been described.5 While the precise mechanisms are still being discovered, current hypotheses support the notion that a somatic mutation results in a second hit, leading to a loss in regulation of the cell cycle and resultant tumors. For instance, melanocytes cultured from café au lait macules were found to exhibit a somatic mutation in the NF1 cell, implying that a loss of heterozygosity resulted in these lesions. However, the occurrence of tumors in Schwann cells, fibroblasts, neurons, epithelial cells, and perineural cells suggests that the condition may also originate from NF1 mutations in ...

In Drosophila, the cyclic adenosine monophosphate (cAMP) pathway has been shown to be crucial for learning and memory, but whether this represents a developmental or a specific effect has not been resolved. Research with a new targeting system that allows both spatial and temporal control of gene expression shows that expression of rutabaga-encoded adenylyl cyclase, a component of the cAMP signaling pathway, in the mushroom bodies of adult flies is necessary and sufficient to rescue the learning.

From: GHR BAP1 tumor predisposition syndrome is an inherited disorder that increases the risk of a variety of cancerous (malignant) and noncancerous (benign) tumors, most commonly certain types of tumors that occur in the skin, eyes, kidneys, and the tissue that lines the chest, abdomen, and the outer surface of the internal organs (the mesothelium). Affected individuals can develop one or more types of tumor, and affected members of the same family can have different types. Some people with BAP1 tumor predisposition syndrome develop growths in the skin known as atypical Spitz tumors. People with this syndrome may have more than one of these tumors, and they can have dozens. Atypical Spitz tumors are generally considered benign, although it is unclear if they can become cancerous. Skin cancers are also associated with BAP1 tumor predisposition syndrome, including cutaneous melanoma and basal cell carcinoma. A type of eye cancer called uveal melanoma is the most common cancerous tumor in BAP1 ...

In infants and children, neurofibromatosis type I can interfere with the development of the spine. The disease can affect the protective covering of the spine, called the dura. Increased pressure in the spinal fluid due to neurofibromas of the spinal nerves can result in dural ectasia, which is a ballooning out of a sac that contains the cerebrospinal fluid. This condition may result in pain in the back and limbs, bladder control problems, and numbness in severe cases. Neurofibromatosis may cause tumors on an around the spinal cord. Even benign tumors in this area can cause pain and weakness in the most severe cases.. Scoliosis, an irregular side curvature of the spine from left to right, and kyphosis, or a rounded or forward angulated back, occur together or separately in about one in five people with neurofibromatosis type I. Osteoporosis is common among neurofibromatosis type I sufferers, who generally have lower bone density by age than healthy individuals. While physical therapy may be able ...

Therefore, a rational therapy for NF1 may be to inhibit Ras signaling. A direct approach to inhibit Ras would be to block its required post-translational processing, e.g., by inhibition of farnesyltransferase. In preclinical studies, for example, FTI have been shown to block proliferation of a human neurofibrosarcoma cell line (Yan et al., 1995) and of Schwann cells derived from a neurofibromin-deficient mouse (Kim et al., 1997). FTI administration also reversed learning deficits in the heterozygous NF1+/- mouse (Costa et al., 2002). There is a currently accruing phase 2 clinical trial of an FTI for progressing plexiform neurofibromas in NF1 (protocol 01-C-0222). It has previously been noted that FTI treatment is not very effective at inhibiting proliferation of hematopoietic cells from neurofibromin-deficient mice, which the authors attributed to the lack of ability of the FTI to inhibit the processing of K- and N-Ras (Mahgoub et al., 1999). Functional connections between neurofibromin ...

Neurofibromatosis type I (NF 1) is an autosomal dominant disorder affecting approximately 1 in 3500 individuals. NF1 exhibits multiple manifestations such as the presence of café-au-late spots, learning disabilities and bone deformities. A large proportion of NF 1 patients display skeletal deformities including alteration in bone size and shape, the presence of scoliosis, and tendency to develop pseudoarthroses. Although the skeletal manifestations of NF1 have long been recognized and studied but only recently recognized as skeletal dysplasia by bone researchers. Craniofacial abnormality occurs in about 7% of NF1 patients and characterized by hypoplasia or absence of greater wing of sphenoid bone. This dysplasia is progressive and always unilateral, results in bulging of one eye and mid-facial bone associated with malocclusion, and is termed Sphenoid Wing Dysplasia (SWD). We have established a breeding colony of neurofibromin (NF1 gene) osteoblast conditional knockout mice. Preliminary result ...

More than 35% of pheochromocytomas and paragangliomas (PPGL) are thought to occur due to an underlying genetic predisposition. 18 susceptibility genes have been identified for PPGL, which explain app. 30% of familial cases. Further PPGL predisposition genes, however, remain to be discovered. In addition, identification of biomarkers for malignancy also remains a current challenge since histologic assessment does not suffice discrimination of malignant PPGLs. Personalized screening protocols, risk stratification measures and surveillance guidelines are needed for PPGL patients and their family members at risk.. We performed panel sequencing for 94 tumor predisposition syndrome (TPS) genes and identified 12 pathogenic germline mutations in 60 PPGL patients. Two of these patients were identified with NF1-mutations although they did not meet the diagnostic criteria for Neurofibromatosis. Thus, TPS gene panel sequencing proved superior to routine Sanger sequencing since mutations were identified in ...

About Huntingtons disease Huntingtons disease is an inherited, progressive and fatal neurodegenerative disorder that affects one in 10,000 people. The disease is now recognised as one of the more common genetic disorders. It typically begins in mid-life, between the ages of 30 and 45, although onset may occur as early as the age of two. Over a period of 10 to 20 years, the disease slowly diminishes the patients ability to walk, think, talk and reason, ultimately making the patient completely dependent upon others for his or her care. In the US, approximately 30,000 patients suffer from the disease with 200,000 people genetically at risk. There are currently no effective treatments or cures for the disease.

Familial hypercholesterolaemia (FH) is a relatively common genetic disorder associated with high risk of coronary heart disease that is preventable by early diagnosis and treatment. In a previous article, we reviewed the evidence for clinical management, models of care and health economic evaluations. The present commentary emphasises that collective action is needed to strengthen our approaches to evidence-based care, including better diagnosis and access to effective therapies. We detail how contemporary innovations in inter-operable, web-based, open-source and secure registries can provide the supporting infrastructure to: (i) address a current gap in the flow of data for measuring the quality of healthcare; (ii) support basic research through provision of high-quality, de-identified aggregate data; (iii) enable equitable access to clinical trials; and (iv) support efforts to disseminate evidence for best practice and information for care services. We describe how these aspects of enabling ...
