Link to Pubmed [PMID] - 28275106. Open Biol 2017 03;7(3). The disrupted-in-schizophrenia 1 () gene was identified as a genetic risk factor for chronic mental illnesses (CMI) such as schizophrenia, bipolar disorder and severe recurrent depression. Insoluble aggregated DISC1 variants were found in the cingular cortex of sporadic, i.e. non-genetic, CMI patients. This suggests protein pathology as a novel, additional pathogenic mechanism, further corroborated in a recent transgenic rat model presenting DISC1 aggregates. Since the potential role of aggregation of DISC1 in sporadic CMI is unknown, we investigated whether DISC1 undergoes aggregation in cell culture and could spread between neuronal cells in a prion-like manner, as shown for amyloid proteins in neurodegenerative diseases. Co-culture experiments between donor cells forming DISC1 aggregates and acceptor cells showed that 4.5% of acceptor cells contained donor-derived DISC1 aggregates, thus indicating an efficient transfer DISC1 aggregates ...

Isolation of the PSD fraction. PSD fractions were prepared from rat forebrains as previously described (Carlin et al., 1980; Cho et al., 1992). Synaptosomes were isolated from homogenates by differential and density gradient centrifugation and then extracted with 0.5% Triton X-100 for 15 min. The resulting One-Triton PSD fraction was pelleted by centrifugation at 36,800 × gfor 45 min. A portion of the One-Triton fraction was extracted again either with 0.5% Triton X-100 for 15 min or with 3%N-lauroyl-sarcosine for 10 min and then pelleted by centrifugation at 201,800 × g for 1 hr to obtain the Two-Triton PSD fraction or the One-Triton plus Sarcosyl PSD fraction, respectively. Protein concentrations were determined by a modified method of Lowrey (Peterson, 1983).. Identification of proteins in the PSD fraction by mass spectrometry. Protein identification was performed by mass spectrometry combined with sequence database searches (Jensen et al., 1998). Protein bands cut from a Coomassie ...

Comrade is a loaded word. Tongzhi, literally same aspiration, was the appropriate term of address for an entire generation of Chinese, from influential Party officials and generals to ordinary mothers, street-sweepers, and butchers. Its usage signified membership in a shared, Communist dream of equality and progress. Sometime in the late-80s, tongzhi took on a secondary meaning for a less public community. It began to mean gay.. Unlike many linguistic changes, this shift was deliberate. The new connotation was proposed by Edward Lam, one of the artist-activists who organized the first Hong Kong Gay and Lesbian Film Festival in 1989. In borrowing and reshaping tongzhi, with its suggestion of unity and shared purpose, they hoped to bring gay Chinese people out of the shadows and into the broader community. That same year, the Tiananmen protests began. Then the Berlin Wall collapsed. Tongzhi took off, but the broader community it once symbolized had fallen apart. You have to wonder if ...
TY - JOUR. T1 - Phosphorylation of CRMP2 (Collapsin Response Mediator Protein 2) is Involved in Proper Dendritic Field Organization. AU - Yamashita, Naoya. AU - Ohshima, Toshio. AU - Nakamura, Fumio. AU - Kolattukudy, Papachan. AU - Honnorat, Jérôme. AU - Mikoshiba, Katsuhiko. AU - Goshima, Yoshio. PY - 2012/1/25. Y1 - 2012/1/25. N2 - Collapsin response mediator proteins (CRMPs) are intracellular proteins that mediate signals for several extracellular molecules, such as Semaphorin3A and neurotrophins. The phosphorylation of CRMP1 and CRMP2 by Cdk5 at Ser522 is involved in axonal guidance and spine development. Here, we found that the Ser522-phosphorylated CRMP1 and/or CRMP2 are enriched in the dendrites of cultured cortical neurons and P7 cortical section. To determine the physiological role of CRMPs in dendritic development, we generated CRMP2 knock-in mutant mice (crmp2ki/ki) in which the Ser residue at 522 was replaced with Ala. Strikingly, the cortical basal dendrites of double mutant ...

Primary malignant lymphoma of the prostate (PMLP) is prone to occur in the elderly, and it has no significant correlation with lactate dehydrogenase (LDH) and prostate specific antigen (PSA). Clinical symptoms and imaging data of PMLP remain unspecific, and its prognosis is poor. A previous result showed that collapsin response mediator protein 4 (CRMP4) promotor methylation can be used as a predictor for lymph node metastases in prostate biopsies. However, the relationship between CRMP4 promotor methylation and PMLP has not been studied. We investigated the clinicopathological features of PMLP and the significance of CRMP4 methylation in PMLP. The clinical data and diagnosis information of 10 patients with PMLP were retrospectively analyzed. The CRMP4 promotor methylation level in paraffin-embedded tissues of the 10 patients with PMLP were determined and then compared to limited prostate cancer (LPCa) and its negative lymph node tissue [LPCa-LN (−) (10 cases)] and also to metastatic prostate

N2 - Joubert syndrome is an autosomal recessive disorder characterized by congenital malformation of the cerebellum and brainstem, with abnormal decussation in the brain. Mutations in the Abelson helper integration site 1 gene, which encodes the protein AHI1, have been shown to cause Joubert syndrome. In this study, we found that mouse Ahi1 formed a stable complex with huntingtin-associated protein 1 (Hap1), which is critical for neonatal development and involved in intracellular trafficking. Hap1-knockout mice showed significantly reduced Ahi1 levels, defective cerebellar development, and abnormal axonal decussation. Suppression of Ahi1 also ...
Huntingtons disease (HD) is caused by polyglutamine expansion (exp) in huntingtin (Htt). The type 1 inositol (1,4,5)-triphosphate receptor (InsP3R1) is an intracellular calcium (Ca2+) release channel that plays an important role in neuronal function. In a yeast two-hybrid screen with the InsP3R1 carboxy terminus, we isolated Htt-associated protein-1A (HAP1A). We show that an InsP3R1-HAP1A-Htt ternary complex is formed in vitro and in vivo. In planar lipid bilayer reconstitution experiments, InsP3R1 activation by InsP3 is sensitized by Httexp, but not by normal Htt. Transfection of full-length Httexp or caspase-resistant Httexp, but not normal Htt, into medium spiny striatal neurons faciliates Ca2+ release in response to threshold concentrations of the selective mGluR1/5 agonist 3,5-DHPG. Our findings identify a novel molecular link between Htt and InsP3R1-mediated neuronal Ca2+ signaling and provide an explanation for the derangement of cytosolic Ca2+ signaling in HD patients and mouse models ...

The collapsin response mediator protein (CRMP) family of intracellular phosphoproteins are predominantly expressed in the nervous system during development. These proteins play important roles in axon formation from neurites, and in neuron guidance, growth, and polarity. CRMP-2 is encoded by the DPYSL2 gene in humans. It is also known as dihydropyrimidinase-like 2 (DRP2), dihydropyrimidinase-related protein 2 (DHPRP2), unc-33-like phosphoprotein 2 (ULIP2), and N2A3. CRMP-2 promotes microtubule assembly and is required for growth cone collapse. It also plays a role in synaptic signaling through interactions with calcium channels. Mutations in the DPYSL2 gene have been implicated in multiple neurological disorders. A hyperphosphorylated form of CRMP-2 may play a key role in the development of Alzheimers disease.. ...

The selectivity of LAG3, neurexin 1β, and APLP1 and related transmembrane proteins for α-syn-biotin PFF versus α-syn-biotin monomers was determined via the ratio of Kd values (Fig. 1B). LAG3 exhibited the highest selectivity with a ratio of 38, followed by neurexin 1β with a ratio of 11 and APLP1 with a ratio of 7. The binding of α-syn-biotin PFF to LAG3 was specific because α-syn-biotin PFF does not bind to the CD4 receptor, which has 20% homology to LAG3 (Fig. 1B and fig. S4). In addition to α-syn-biotin PFF binding to neurexin 1β, it also binds to neurexin 3β and mildly binds to neurexin 1α and neurexin 2β (Fig. 1B). α-Syn-biotin PFF does not bind the amyloid precursor protein (APP) or the amyloid precursor-like protein 2 (APLP2), suggesting that the binding to APLP1 was specific (Fig. 1B). Because LAG3 exhibited the highest selectivity for α-syn-biotin PFF, it was advanced for further study. No LAG3 immunoreactive band was observed in HEK293FT and SH-SY5Y cells, which is ...
NUB1 suppression of Huntington toxicity: mechanistic insights Yao Yao, Boxun Lu Department of Biophysics, School of Life Sciences, Fudan University, Shanghai, Peopleâ s Republic of China Abstract: Huntingtonâ s disease (HD) is an autosomal dominant neurodegenerative disorder marked by chorea, dystonia, incoordination, and cognitive and motor disturbance. The major cause of HD is the cytotoxicity of the mutant huntingtin protein (mHTT), encoded by the mutant HTT gene. The mechanism by which mHTT leads to cytotoxicity and neuronal death is unclear, and thus enhancing clearance of the mHTT protein is likely to be an effective approach to treat HD. We have recently identified NUB1 (negative regulator of ubiquitin-like proteins 1) as a modifier of mHTT levels via enhancement of its proteasomal degradation. In this review, we will discuss the mechanism of NUB1-mediated mHTT clearance and potential targeting strategies. Keywords: drug target discovery, Huntingtonâ s disease, NEDD8, ubiquitination

Additionally, JIP-1-induced activation can be Suggestion60 3rd party, whereas a complicated with Help, Fe65, and Suggestion60 can be shaped for Fe65-induced activation. Finally, and most interestingly probably, we display that even though the APP family APLP1 and APLP2 (for amyloid precursor-like protein) can cause activation in combination Rabbit polyclonal to AACS with Fe65, APLP1 and APLP2 show little or no activation in combination with JIP-1. This activity for the AID fragment may help explain the unique functions of APP relative to its other family members, and changes in gene expression found in Alzheimers disease. The importance of amyloid protein ...
In Huntingtons disease there is a characteristic selective loss of neurons. The finding of pathological intraneuronal protein aggregations, that partially consist of huntingtin fragments, was suggested to be the cause of nerve cell loss. This histological study on postmortem brain tissue now shows a dissociation between huntingtin aggregation and the selective pattern of nerve cell loss. In primary degenerating brain regions and nerve cell subpopulations, there are significantly fewer intraneuronal huntingtin aggregates than in regions and neurons that are relatively spared in the degenerative process. Furthermore, it is observed that within vulnerable nerve cell subpopulations there are degenerating neurons that don t contain any huntingtin aggregates, while in neurons that are relatively spared from degeneration there are strikingly often perikaryal and intranuclear huntingtin aggregates. These observations indicate that huntingtin aggregations per se are not directly responsible for cell ...

Title: Increased CRMP2 Phosphorylation is Observed in Alzheimers Disease; Does this Tell us Anything About Disease Development?. VOLUME: 6 ISSUE: 3. Author(s):M. P.M. Soutar, P. Thornhill, A. R. Cole and C. Sutherland. Affiliation:Biomedical Research Institute, University of Dundee, Ninewells Hospital, Dundee DD1 9SY, Scotland, United Kingdom.. Abstract: Collapsin response mediator protein-2 (CRMP2) was recently identified as a physiological substrate for GSK3 and Cdk5, two protein kinases suggested to exhibit greater activity in Alzheimer s disease (AD). Indeed, phosphorylation of CRMP2, at the residues targeted by GSK3 and Cdk5, is relatively high in cortex isolated from human AD brain, as well as in the brains of animal models of AD, while phospho-CRMP2 is found in neurofibrillary tangles. In mouse models of AD, increased phosphorylation occurs prior to pathology. Although CRMP2 has no known enzymatic activity, a great deal of information is appearing on its importance in neuronal ...
Background and purpose: Glia maturation factor (GMF), a brain specific protein, discovered and characterized in our laboratory, induces expression of proinflammatory cytokines/ chemokines in the central nervous system (CNS). Recently, it has been demonstrated that deficiency of GMF mitigates neuronal damage in tissue culture cell and animal models of neurodegeneration. Since, GMF expression in brain enhances inflammation; we tested the hypothesis that deficiency of GMF abrogates the inflammatory responses in experimental model of ischemic stroke.. Methods: Transient focal cerebral ischemia was induced by 1 hour of occlusion of the right middle cerebral artery (MCAO) with a 7.0 monofilament in GMF-containing wild type (Wt) and GMF-deficient (GMF-KO) mice. Mice were anesthetized with 1-1.5% isoflurane mixed with medical oxygen. Body temperature was maintained at 37°C ± 1.0 using a heating pad. At 23 hours after ischemia/reperfusion, mice were tested for neurological scores and were sacrificed ...

Here, we analysed the relative contribution of each phosphorylatable residue in the N17 region (T3, S13 and S16) towards huntingtin exon 1 (HTTex1) oligomerization, aggregation and toxicity in human cells and Drosophila neurons.We used bimolecular fluorescence complementation to show that expression of single phosphomimic mutations completely abolished HTTex1 aggregation in human cells. In Drosophila, mimicking phosphorylation at T3 decreased HTTex1 aggregation both in larvae and adult flies. Interestingly, pharmacological or genetic inhibition of ...

N2 - Accumulative aggregation of mutant Huntingtin (Htt) is a primary neuropathological hallmark of Huntingtons disease (HD). Currently, mechanistic understanding of the cytotoxicity of mutant Htt aggregates remains limited, and neuroprotective strategies combating mutant Htt-induced neurodegeneration are lacking. Here, we show that in Drosophila models of HD, neuronal compartment-specific accumulation of mutant Htt aggregates causes neurodegenerative phenotypes. In addition to the increase in the number and size, we discovered an age-dependent acquisition of thioflavin S+, amyloid-like adhesive properties of mutant Htt aggregates and a concomitant progressive clustering of aggregates with mitochondria ...
A novel gene therapy drug developed by antibody company Vybion has been shown to block cellular gene dysregulation and delay cognitive and motor problems associated with Huntingtons disease. The details of the intrabody drug INT41, an antibody that binds to an intracellular protein, were published in the Journal of Neurodegenerative Diseases.. INT41 prevents toxic N-terminal huntingtin fragments from being transported into the nucleus of the cell and blocks them from binding with the DNA. The drug was tested in the well-validated R6/2 mouse model of Huntingtons disease.. We believe that our therapeutic approach to the treatment of Huntingtons disease has provided a biological rationale linking Huntingtons disease progression and toxic N-terminal fragments, said Dr. Lee Henderson, CEO of Vybion. We look forward to completing our plans for human patient trials.. The drug candidate is currently in late-stage preclinical development for the treatment of Huntingtons disease. Vybions ...

Huntingtons disease (HD) is an autosomal dominant, progressive neurodegenerative disease caused by an expanded polyglutamine (polyQ) tract in the N-terminal region of mutant huntingtin (mHtt). As a result, mHtt forms aggregates that are abundant in the nuclei and processes of neuronal cells. Although the roles of mHtt aggregates are still debated, the formation of aggregates points to deficient clearance of mHtt in brain cells. Since the accumulation of mHtt is a prerequisite for its neurotoxicity, exploring the mechanisms for mHtt accumulation and clearance would advance our understanding of HD pathogenesis and help us develop treatments for HD. We know that the ubiquitin-proteasome system and autophagy play important roles in clearing mHtt; however, how mHtt preferentially accumulates in neuronal nuclei and processes remains unclear. Studying the clearance of mHtt in neuronal cells is a challenge because neurons are morphologically and functionally polarized, which means the turnover of mHtt may be
Manhasset, NY - Investigators at The The Feinstein Institute for Medical Research have discovered a new way to measure the progression of Huntingtons disease, using positron emission tomography (PET) to scan the brains of carriers of the gene. The findings are published in the September issue of The Journal of Clinical Investigation.. Huntingtons disease causes the progressive breakdown of nerve cells in the brain, which leads to impairments in movement, thinking and emotions. Most people with Huntingtons disease develop signs and symptoms in their 40s or 50s, but the onset of disease may be earlier or later in life. Medications are available to help manage the symptoms of Huntingtons disease, but treatments do not prevent the physical, mental and behavioral decline associated with the condition.. Huntingtons disease is an inherited disease, passed from parent to child through a mutation in the normal gene. Each child of a parent with Huntingtons disease has a 50/50 chance of inheriting ...
High throughput screening Scientists know that the faulty huntingtin protein causes HD, but how it kills cells is not fully known. By screening hundreds of compounds, scientists hope to find one that prevents the aggregation or cleavage of the mutant huntingtin protein - and thereby stops the cells being killed. If successful, they will try this in tissue culture, then examine the effects on animals carrying the faulty HD gene. If the results of both these are successful, the compound can be safety tested in preparation for human trials. ...
Two neuron-specific proteins, neurogranin (Ng), and neuromodulin (GAP43), were studied. Our first aim was to know the potentiality of various chemicals for their induction of Ng mRNA expression; our second one was to know the intracellular localization of GAP43 and its co-localization with calmodulin (CaM). Our results indicated that although some of the NO donors could enhance Ng promoter activity, they could not induce Ng mRNA expression in HEK293 and PC12 cells. Moreover, our findings revealed that Ng mRNA could be induced only by NGF and only in PC12 cells. For GAP43b s intracellular localization and co-localization with CaM, our results revealed DsRed-GAP43 and its mutants (S41D, S41G) were expressed mainly in the region near to cell membrane while EGFP-GAP43 and its mutants (S41D, S41G) were mostly distributed in cytoplasm. PMA treatment did not affect the localization of GAP43. For the co-transfection experiments, a particular region of co-localization of GAP43 and CaM was found to be ...
LC3-mHTT-IN-2 (Compound AN2) is a mHTT-LC3 linker compound, which interacts with both mutant huntingtin protein (mHTT) and LC3B but not with wtHTT or irrelevant control proteins. LC3-mHTT-IN-2 reduces the levels of mHTT in an allele-selective manner in cultured Huntington disease (HD) mouse neurons. - Mechanism of Action & Protocol.
Our enthusiasm for this program is bolstered by a compelling set of preclinical data that demonstrated selectivity, potency, and durability of WVE-003 with effects in relevant brain regions. Further, emerging data continue to indicate that a fundamental requirement for clinical success in HD treatment will be the need to preserve wild-type HTT protein, supporting our allele-selective approach to mutant HTT protein reduction.. Waves approach to HD and the WVE-003 program is guided by the recognition that, in addition to a gain of function of the mHTT protein, people with this disease have lost one copy of the wtHTT allele, leaving them with a smaller protective reservoir of healthy protein than unaffected individuals. A growing body of scientific evidence suggests that preserving as much of this essential wtHTT protein as possible, when in the setting of stress from the toxic mHTT protein, may be important for favorable clinical outcomes.. WVE-003 incorporates the companys novel PN backbone ...
These data are consistent with previous reports of intronic miRNA function, in which the miRNA regulates the same biological process as the protein encoded by the host gene.29 miR-218 may contribute to fine-tuning of Slit-Robo pathway genes or generate negative feedback in response to Slit gene activation. It is interesting to speculate that miR-218 may serve to repress the expression of the Robo1/2 receptors in the Slit ligand-expressing cells, thereby spatially separating ligand from receptor. Because Robo4 is not a target of miR-218 regulation, it also is possible that miR-218 affects the ratio of Robo1/2 and Robo4 proteins, thereby influencing vascular patterning.. It is currently debated whether the Robo1 and -2 receptors provide a positive or negative influence on EC migration, although Robo4 is generally thought of as a repulsive or stabilizing cue during vascular pathfinding.9,37 In our hands, it appears that repression of Robo1/2 and HSPG biosynthetic molecules by miR-218 negatively ...

A defect in a single gene causes Huntingtons disease. Its considered an autosomal dominant disorder. This means that one copy of the abnormal gene is enough to cause the disease. If one of your parents has this genetic defect, you have a 50 percent chance of inheriting it. You can also pass it on to your children.. The genetic mutation responsible for Huntingtons disease is different from many other mutations. There isnt a substitution or a missing section in the gene. Instead, there is a copying error. An area within the gene is copied too many times. The number of repeated copies tends to increase with each generation.. In general, symptoms of Huntingtons disease show up earlier in people with a larger number of repeats. The disease also progresses faster as more repeats build up.. ...
How do you get Huntingtons disease?. Huntingtons disease is caused by a faulty gene, which is passed from parent to child. The faulty gene makes a faulty protein called huntingtin.

In collaboration with Dr. Macdonald and others at CHDI, the Isis HD team is working to validate huntingtin lowering biomarkers. Beside the development of assays (investigative procedures) to measure the huntingtin protein in CSF, CHDI is also looking at PET-ligands to measure the effects of ISIS-HTTRx in the brain. The ligand, sometimes called a PET tracer, binds to a target or receptor in the brain, which can be measured in people using PET scan imaging. The team has selected ligands to targets that are altered in HD; the hope is that when huntingtin is lowered the level of these targets will be restored, indicating that ISIS-HTTRx has a desired effect ...
The idea is simple, keep the traffic flowing when the driver reaches a junction. Rather than waiting for a light to change or a policeman to allow progress, the roundabout simply allows traffic to merge and continue onwards. For low flows of traffic, everything works smoothly however when volumes increase, it can cause the same problem that it was designed to prevent - a backup of traffic entering the junction.. In most countries, drivers have to give way to vehicles already using the junction, however in some, it is the opposite - drivers already using the junction have to let others in which increases the traffic in the junction and defeats the purpose of the design! It is also common to see a lack of planning on or near a roundabout ...
