FVCOM has been validated through direct comparison with analytical solutions for idealized cases (Chen et al., 2005b; Huang et al., 2005a-c) and other models for application in estuaries (Chen et al., 2005d-e; Huang et al., 2005d), inter-bays (Zhao et al., 2005) and the GOM/GB region (Chen et al, 2003b; Chen et al., 2005c). These studies show that different physical processes controlling currents and stratification in the coastal ocean have inherent time and space scales that must be carefully considered when determining model grid resolution for accurate simulation. This is particularly important with freshwater discharge, buoyancy-driven coastal plumes and currents, tidally-forced flows and upwelling, and fronts in the GOM/GB region (Chen et al 2005a). For example, model dye experiments made to simulate Houghtons May/June 1999 dye dispersion observations on GB suggest that the horizontal resolution needed to resolve the diffusive flux is 500 m (Chen et al., 2005c). This resolution is also ...

The P. syringae AvrRpt2 Type III Secreted effector protein alters host auxin physiology. The P. syringae AvrRpt2 protein is injected directly into plant cells via the Type Three Secretion System (TTSS). It has been proposed that the primary function of effector proteins such as AvrRpt2 is to promote pathogen virulence, and this has been demonstrated for several TTSS-secreted proteins. However, the function of these proteins, and the mechanisms by which they contribute to disease development are not well understood. We have shown that AvrRpt2 functions as a virulence factor on both A. thaliana and tomato plants (Chen et al, 2000; Lim and Kunkel, 2005). Using transgenic A. thaliana plants that produce the AvrRpt2 protein, we have demonstrated that this bacterial protein functions inside the plant to promote pathogen growth and development of disease (Chen et al, 2000). This was the first time a type III-injected protein was shown to promote virulence from within a plant cell. Our more recent ...
The foliar pathogen Pseudomonas syringae is a useful model for understanding the role of stress adaptation in leaf colonization. We investigated the mechanistic basis of differences in the osmotolerance of two P. syringae strains, B728a and DC3000. Consistent with its higher survival rates following inoculation onto leaves, B728a exhibited superior osmotolerance over DC3000 and higher rates of uptake of plant-derived osmoprotective compounds. A global transcriptome analysis of B728a and DC3000 following an osmotic upshift demonstrated markedly distinct responses between the strains; B728a showed primarily upregulation of genes, including components of the type VI secretion system (T6SS) and alginate biosynthetic pathways, whereas DC3000 showed no change or repression of orthologous genes, including downregulation of the T3SS. DC3000 uniquely exhibited improved growth upon deletion of the biosynthetic genes for the compatible solute N-acetylglutaminylglutamine amide (NAGGN) in a minimal medium, due
Neurons express functional GABA receptors very early in development (Fiszman et al., 1990; Walton et al., 1993; Chen et al., 1995). Some embryonic, but not mature, neurons show Ca2+ rises in response to GABA (Reichling et al., 1994; Ben-Ari et al., 1989; Yuste and Katz, 1991; Obrietan and van den Pol, 1995a). Embryonic neurons both in culture and in brain slices can be depolarized by GABA (Obata et al., 1978; Connor et al., 1987;Ben-Ari et al., 1989; Cherubini et al., 1991; Chen et al., 1996), leading to the possibility that GABA can play an excitatory role in early development (Cherubini et al., 1991). The depolarizing activity of GABA in the present study in traumatized neurons is caused by a depolarized Cl− reversal potential, a condition that results in Cl− exit rather than entry when GABA-gated channels are open. What is striking about the present results is that they indicate a very rapid (minutes) reversal of the role of GABA. That this result is not simply attributable to ...
Previous work demonstrated that egg surface CD9 is essential for sperm-egg fusion (Kaji et al., 2000; Le Naour et al., 2000; Miyado et al., 2000), but nothing is known about how CD9 acts in this system. Egg CD9 could bind in trans to a counter-receptor on sperm as suggested for CD81 on astrocytes interacting with neurons (Kelic et al., 2001). Alternatively, CD9 may function by cis interactions on the egg surface with other egg surface molecules. One egg protein suggested to interact in a physiologically significant way with CD9 is the integrin α6β1 (Chen et al., 1999; Miyado et al., 2000). However, eggs lacking α6β1 fuse normally with sperm, so a role for this integrin in gamete fusion is in doubt (Miller et al., 2000).. The anti-CD9 monoclonal antibody KMC8 blocks sperm-egg fusion (Chen et al., 1999; Miller et al., 2000), and we found that KMC8 binds to constructs containing CD9 EC2, suggesting a role for EC2 in the fusion process. The EC2 constructs, preincubated with sperm, had no ...
Recent studies described the phenotype of Fezl-deficient mice. Similarly to zebrafish, mammalian Fezl is expressed in the telencephalon and diencephalon (Hirata et al., 2004; Mutsuga et al., 2005). In the mouse telencephalon, Fezl is required for fate specification and axonal projections of cortico-spinal motor neurons, subplate cortical neurons and deep-layer pyramidal neurons (Chen et al., 2005a; Chen et al., 2005b; Hirata et al., 2004; Molyneaux et al., 2005). A close homolog of Fezl, denoted Fez, is expressed in the mouse hypothalamus in partially overlapping domains with Fezl and fez-fezl double deficient mouse displays defects in diencephalic subdivisions (Hirata et al., 2006a; Hirata et al., 2006b). A similar role for zebrafish Fezl in diencephalic patterning was also reported (Jeong et al., 2007).. The precise regulation of Otp, DA and IT by the tof m808 hypomorph (Figs 1 and 3) allows us to separate the role of Fezl in regional patterning from its more selective role in cell ...
Gonadotrophin-releasing hormone (GnRH) is a key regulator of reproduction in all vertebrates. We first cloned the cDNA and genomic DNA sequences coding for GnRHa gene in the orange-spotted grouper (Epinephelis coioides), an economically important marine fish, and then cloned its promoter sequence. The region responsible for the cell-specific expression of GnRHa was located between -2005 bp to -956 bp from the translation start site. GnRHa promoter driven EGFP expression in transgenic zebrafish showed that GnRHa-positive neurons were primarily located in the midbrain and in the eyes. Our results provide an improved understanding of the regulatory mechanism and function of GnRHa of E. coioides ...
The BiBiServ team discontinued the online service for AGt_SDP. Please contact the author(s) of AGT-SDP for any questions concerning AGT-SDP. In unbound protein--protein docking, the complex of two proteins is predicted using the unbound conformations of the proteins (Halperin et al.,2002). For testing of docking algorithms, two unbound proteins which form a known complex have to be identified, so that the result of the docking algorithm can be compared to the known complex. For the identification of test cases, the structures taken from the PDB have to be classified as unbound proteins or complexes and unbound proteins with a 100% sequence identity to one complex part have to be searched. By now, most groups use handpicked test sets. The largest collection of test cases used so far is described by Chen et al. (Chen et al.,2003) and contains 31 test cases for unbound docking. Because of the exponential growth of available protein structures in the PDB, automatic generation of test cases will ...

Substrate roughness influences the wetting properties of self-assembled monolayers (SAMs), but details on this dependency at the sub-nanometer level are still lacking. This study investigates the effect of surface roughness on interfacial properties of n-alkanethiolate SAMs, specifically wetting, and confirms the predicted limit to the observation of the odd-even effect in hydrophobicity. This article studies static contact angles of polar and nonpolar probe liquids on a series of n-alkanethiolate SAMs on surfaces with tunable roughness. We prepared Ag surfaces with root-mean-square roughness (Rrms) of ∼0.6-2.2 nm and compared the wetting properties of n-alkanethiolate SAMs fabricated on these surfaces. We measured the static contact angles, θs, formed between SAM and probe liquids [water, glycerol, and hexadecane]. Hexadecane showed an odd-even effect on all surfaces irrespective of the degree of roughness. Polar liquids (water and glycerol), however, showed a dependency on the roughness of the
Our aim was to examine the impact of TLR5 ligation in rheumatoid arthritis (RA) and experimental arthritis pathology. Studies were conducted to investigate the role of TLR5 ligation on RA and mouse myeloid cell chemotaxis or osteoclast formation, and in addition, to uncover the significance of TNF-alpha function in TLR5-mediated pathogenesis. Next, the in vivo mechanism of action was determined in collagen-induced arthritis (CIA) and local joint TLR5 ligation models. Last, to evaluate the importance of TLR5 function in RA, we used anti-TLR5 Ab therapy in CIA mice. We show that TLR5 agonist, flagellin, can promote monocyte infiltration and osteoclast maturation directly through myeloid TLR5 ligation and indirectly via TNF-alpha production from RA and mouse cells. These two identified TLR5 functions are potentiated by TNF-alpha, because inhibition of both pathways can more strongly impair RA synovial fluid-driven monocyte migration and osteoclast differentiation compared with each factor alone.

The first evident break in left-right symmetry of the primitive zebrafish heart tube is the shift in pattern of BMP4 expression from radially symmetric to left-predominant. The midline heart tube then jogs to the left and subsequently loops to the right. We examined 279 mutations, affecting more than 200 genes, and found 21 mutations that perturb this process. Some cause BMP4 to remain radially symmetric. Others randomize the asymmetric BMP4 pattern. Retention of BMP4 symmetry is associated with failure to jog: right-predominance of the BMP4 pattern is associated with reversal of the direction of jogging and looping. Raising BMP4 diffusely throughout the heart, via sonic hedgehog injection, or the blocking of its action by injection of a dominant negative BMP4 receptor, prevent directional jogging or looping. The genes crucial to directing cardiac asymmetry include a subset of those needed for patterning the dorsoventral axis and for notochord and ventral spinal cord development. Thus, the ...
Ultrathin Pb films with a thickness of three monolayers (ML) were prepared on α-3×3Pb/Si(111) (Pb-SIC) substrate by molecular beam epitaxy. Despite significant defect scattering, low temperature scanning tunneling microscopy reveals a high superconducting transition temperature Tc of 6.9 K, compared with the bulk Tc (7.2 K). By applying external magnetic field, magnetic vortices were directly imaged, which demonstrates the robustness of superconductivity. By comparing to nearly free-standing Pb films on graphitized SiC (0001) substrate, we suggest that the higher Tc of 3 ML Pb films on Pb-SIC originates from the combined effects of quantum confinement and substrate-enhanced electron-phonon coupling.
The constructs of teacher cognition and teacher identity have recently gained considerable attention in second language teacher education research for their crucial roles in understanding teacher learning. While a number of current studies have examined the contributions of both constructs, the connections between cognition and identity are yet to be fully conceptualized. This article addresses this gap by drawing on the notion of identification to examine the identity construction and cognition development of 15 student teachers in the context of a postgraduate course on pronunciation pedagogy. Questionnaires, focus group interviews, observations, and semi-structured interviews were triangulated to obtain an in-depth understanding of the complex relations between identity formation and cognition growth. Findings revealed that identity construction-manifested through imagination of self and others, engagement and investment in the course, and alignment with course content-not only had a profound impact

In the laboratory, yeast is usually grown in the presence of high glucose, and lab yeast is adapted for those conditions. If strains more typical of wild yeast are maintained under conditions with few nutrients, they will show a synchronous cycle of alternating respiratory and glycolytic metabolism. Cell division is confined to the glycolytic (or reductive) phase. Chen et al. hypothesized that this occurs to prevent replication from taking place in an oxidizing environment, which could cause mutations. When cells were forced to divide during the oxidizing phase of the metabolic cycle by introducing one of several cell cycle mutations or treating with H2O2, an increased level of DNA mutation was indeed observed. In addition, a mutation in a DNA checkpoint kinase that links the cell and circadian cycles in other fungi disrupts cell synchrony, suggesting parallels between the metabolic and circadian cycles..

A previous study described a delay in radial sorting at developmental stages (E17.5 to P24) after Rac1 knock-out (Benninger et al., 2007; Nodari et al., 2007). Our study at later time points (P0-P120) support a major role for Rac1 in SC myelination. We found that myelin sheaths do not form in the Rac1 mutant mice at P15, P30, P60, and P120, although most SCs establish one-to-one relationship with large axons. Thus, we conclude that Rac1 is required at the initiation of SC myelination, after axonal sorting is complete. These differences in phenotypes may be attributable to strain background differences and/or be related to the difference in gene targeting strategies (Benitah et al., 2005; Cappello et al., 2006; Chen et al., 2006; Chrostek et al., 2006; Castilho et al., 2007). Consistent with our results that Rac1 is critical for SC myelination, a recent study reported that active Rac1 is localized to the axon-glial interface in SCs by Par3 and that polarization of Rac1 activation is critical for ...
There are about 16 species of Regmatodon in the world. Most species are distributed around the tropical zones in a disconnected manner. Some bryologists placed the genus in a monotypic family, Regmatodontaceae, based on some unique features such as the peristome inserted below the capsule mouth and exostome teeth apparently shorter than endostome segments. Eight taxa of Regmatodon were recorded in the Chinese flora in the literature (Redfearn et al. 1996). Herzog (1925) first reported R. orthostegius Mont. from Yunnan province. Brotherus (1929) described two new taxa, R. declinatus var. minor Broth. from Guizhou and R. handelii Broth. (= R. orthstegius Mont.) from Yunnan as well as reporting R. polycarpus (Griff.) Mitt. (= R. orthostegius) from these two provinces. Bartram (1935) reported R. declinatus (Hook.) Brid. from Guangxi. P.-C. Chen et al. (1978) listed 4 species from China, with R. schwabei Herz. (= R. declinatus) reported new to the country. C. Gao (1981) published a new species, R. ...
For FLAG-ADD1, the human ADD1 cDNA from pEGFP-C1-ADD (Chen et al., 2007) was cloned into pCMV-3Tag-3A vector (Agilent Technologies) by SacI and BamHI sites. For deleted mutants of FLAG-ADD1, the corresponding cDNA fragments were amplified by PCR using pCMV-3Tag-3A-ADD1 as the template with the following primers and were subcloned into pCMV-3Tag-3A vector. For the Δtail mutant (aa 1-430), the forward primer was 5′-CGGGATCCCGATGAATGGTGATTCTCGTGCTGCG-3′, and the reverse primer was 5′-GAATTCGCAAGTGCCCGAATCACCGTCACT-3′. For the head domain (aa 1-350), the forward primer was 5′-CGGGATCCCGATGAATGGTGATTCTCGTGCTGCG-3′, and the reverse primer was 5′-GGAATTCTTTGTACTTCTCAGGATTCAGCAGGAC-3′. For the tail domain (aa 431-737), the forward primer was 5′-CGGGATCCATGTGCTCCCCACTCAGACACAGTTTT-3′, and the reverse primer was 5′-GGAGAATTCGAGTCACTCTTCTTCTTGCT-3′. All point mutations in pCMV-3Tag-3A-ADD1 were generated by the site-directed mutagenesis kit (QuikChange; Agilent Technologies) and ...
Our laboratory has recently taken an interest into the biogenesis, regulation and function of small nucleolar (sno)RNAs. Most vertebrate snoRNAs are encoded within the introns of highly expressed protein-coding or lncRNA genes - so-called snoRNA host genes. The maturation of intron-hosted snoRNAs generally depends on the splicing process, and therefore snoRNA production gives rise to two decoupled, putatively functional RNA species. We are actively investigating the interplay between and regulation of expression of snoRNAs and their hosts at several levels. Examples of some of our published observations within this area of research are: (1) spliced snoRNA host transcripts that reach the cytoplasm are more often subjected to nonsense-mediated mRNA decay compared to general protein-coding genes (Lykke-Andersen, Chen et al., 2014; Lykke-Andersen and Jensen, 2015), (2) nuclear localized spliced snoRNA host transcripts are identified by the PAXT connection and degraded by the RNA exosome (Meola, ...

Correlates of value are routinely seen in the prefrontal cortex (PFC) during reward-guided decision producing. these neurons also maintain coding of selected worth from choice with the delivery of prize, offering a potential neural system for preserving predictions and upgrading stored beliefs during learning. These results reveal that within PFC, variability in temporal specialisation across neurons predicts participation in particular decision-making computations. DOI: http://dx.doi.org/10.7554/eLife.18937.001 across different cellular material within confirmed area (Kennerley et al., 2009; Kennerley and Wallis, 2010; Meister et al., 2013). The foundation and functional need for this neuronal heterogeneity continues to be unclear. Neurons also display heterogeneity within their (Chen et al., 2015). The temporal receptive field of the neuron could be set up by evaluating its spike-count autocorrelation function (ACF) at relax (Ogawa and Komatsu, 2010). A decaying ACF whilst at relax shows ...
Our research focuses on studying brain transcriptome using next-generation sequencing, in particular, RNA-Seq technique. We are interested in region-specific gene expression profiles in brain development and ageing as well as perturbation of the transcriptome as a result of neurodegeneration.. Recent advances in genomic technology allowed to uncover new RNA species, circular RNAs (circRNAs; Fig. 1). CircRNAs have been identified as a naturally occurring family of widespread and diverse endogenous noncoding RNAs that may regulate gene expression in mammals (Huang et al. 2017) and are perturbed as a result of neurodegeneration (Chen et al. 2016). They are unusually stable RNA molecules with cell type- or developmental stage-specific expression patterns. However, the role of circRNAs in molecular biology of the brain remains unknown. Hence, the aim of this project is to investigate changes in circRNA expression signatures in mouse and human neocortex. The second research aim is to discover new ...
PEDV has become a major economic concern for North American pig producers since it was first identified in the United States in 2013 (Stevenson et al., 2013; Chen et al., 2014). The lack of highly effective vaccines and the relative ineffectiveness of common treatment methods have led to a search for alternative methods of treating and preventing outbreaks. The inclusion of SDP into the diets of young pigs has been shown to have health benefits for other diseases. This study was designed to determine whether there is any benefit to adding BovSDP to the diet during PEDV infection. Supplementing feed rations of pigs, fish, poultry, cats, and dogs with SDP as protein source is performed on a regular basis. SDP is a protein-rich product obtained from blood from healthy animals (cattle or pigs) at slaughter (Torrallardona, 2010; Pérez-Bosque et al., 2016). In pet food, SDP is a preferred binder in canned food products due to its high-protein content and its physicochemical properties (Polo et al., ...
Cell Culture, Drug Treatment, and Cytotoxicity Assay. Human hepatoma HepG2 cells were purchased from American Type Culture Collection (Manassas, VA) and cultured according to a method described previously (Chen et al., 2000). Ketamine was dissolved in phosphate-buffered saline (0.14 M NaCl, 2.6 mM KCl, 8 mM Na2HPO4, and 1.5 mM KH2PO4). Concentrations of ketamine (≤100 μM), which correspond to clinical plasma concentrations (Domino et al., 1982; Grant et al., 1983), were chosen as the treated dosages in this study. To avoid drug interaction, when HepG2 cells were exposed to ketamine, the culture medium did not contain serum and antibiotics. Levels of γ-glutamyltranspeptidase and lactate dehydrogenase in the culture medium were measured to evaluate the cytotoxicity of ketamine to HepG2 cells as described previously (Wu et al., 2007).. Confocal Microscopic Analyses of F-Actin and Microtubular Cytoskeletons. The F-actin and microtubular cytoskeletons in HepG2 cells were visualized as described ...
The success and safety of DREZ-T in the treatment of intractable central pain caused by cervical root(s) avulsion have been confirmed repeatedly [2],[6]-[10],[13]-[15]. Generally, an immediate loss of pain can be achieved in 60 to 80% of cases, but the percentage decreases as time-after-accident increases. Some studies have found that the pain returns to some degree after several years in up to one-fifth of patients [2],[13],[14]; however, this was not confirmed by our study. Severe pain returned after several months only in two cases from Group III, none of the other patients reported any significant worsening or change of the quantity of residual pain over time. Some patients reported a change of quality of pain or irritations, but the change did not have a significant impact on their opinion regarding the effectiveness of the surgery.. An operative painkilling surgery is generally required in 10 to 15% of patients with spinal cord root avulsion [16],[17]. Chen et al., for example, found that ...
The G12 subfamily members Gα12 and Gα13 are well-documented as utilizing RhoGEFs as downstream signaling effectors. Crystallographic studies by Chen et al. [20] and Hajicek et al. [21] have provided intricate structural details of the interaction between Gα13 and the RH domain of p115RhoGEF, identifying a set of Gα13 residues that directly contact this target protein. The structure of Gα12 also has been elucidated, using a chimera comprised of amino acids 49-379 of Gα12 preceded by amino acids 1-28 of Gαi1[22]. However, a Gα12:RhoGEF complex has not been reported. In the current study, we utilized in vitro and cell-based approaches to examine the interaction between Gα12 and two putative target RhoGEFs, LARG and p115RhoGEF. Using immobilized RGS-homology (RH) domains of these RhoGEFs, we identified several substitutions of native amino acids in Gα12 that disrupted its binding to these proteins and blocked its ability to stimulate the Rho-dependent process of SRE-mediated transcription. ...

In the presence of DNA damage, the protein kinase Chk1 can effect cell cycle arrest. Chen et al. determined the crystal structure of the Chk1 kinase domain (Chk1KD), and have uncovered some of its regulatory mechanisms. In the presence or absence of the nonhydrolyzable analog AMP-PNP, no conformational change was observed in the Chk1KD ATP binding site, catalytic residues, or activation loop. Therefore, the conformation of Chk1KD approximates its activated ATP-bound state, and Chk1 does not appear to require activation loop phosphorylation before activity. The authors determined that the regulation of Chk1 may be controlled by its COOH-terminal region; the kinase activity of Chk1KD was 20 times that of full-length Chk1, and autophosphorylation of full-length Chk1 did not inherently affect its kinase activity. The authors speculate on the role of the COOH-terminus in autoinhibition. The crystal structure of the linker region between the kinase domain and the COOH-terminal region indicates that, ...

Mucus obstruction is a hallmark of cystic fibrosis (CF) airway disease, leading to chronic infection, dysregulated inflammation, and progressive lung disease. As mucus hyperexpression is a key component in the initiation and perpetuation of airway obstruction, the triggers underlying mucin release must be identified and understood. In this issue of the JCI, Chen et al. sought to delineate the mechanisms that allow IL-1α/IL-1β to perpetuate the mucoinflammatory environment characteristic of the CF airway. The authors demonstrated that IL-1α and IL-1β stimulated non-CF human bronchial epithelial (HBE) cells to upregulate and secrete both MUC5B and MUC5AC in a dose-dependent manner, an effect that was neutralized by the inhibition of the IL-1α/IL-1β receptor (IL-1R1). Further experiments using mouse models and excised lung tissue identified contributors that drive a vicious feedback cycle of hyperconcentrated mucus secretions and persistent inflammation in the CF airway, factors that are ...

Lesioning studies performed nearly 100 years ago identified the hypothalamus as a critical structure for the control of food intake. However the dynamics of the hypothalamic circuits that give rise to feeding behavior have long been a mystery. In 2015, we reported the first measurements of the activity dynamics of hypothalamic neurons that control hunger (AgRP neurons) in awake, behaving mice (Chen et al., Cell 2015). Prior to our work, these cells were thought to be regulated primarily by hormones and nutrients that circulate in the blood, such that their activity would gradually fluctuate in unison with changes in nutritional state. We discovered unexpectedly that these hunger neurons are also potently regulated by sensory cues associated with food: that is, we found that merely showing a piece of food to a hungry mouse was sufficient to shut off its AgRP neurons within seconds, often before a single bite of food could be consumed. We showed that this sensory regulation resembles an expected ...
Inhib ition of overphosphorylated Akt is usually a promising target ther apy in colorectal cancer . We observed pAkt overexpression in all three cell lines and subsequent downregulation following TSA treatment method. A very similar phenomenon was reported in other research. Chen et al. demon strated that HDACi triggered Akt dephosphorylation in U87MG glioblastoma and Computer 3 prostate cancer cells by disrupting HDAC protein phosphatase one complexes. LBH, one more HDACi using a chemical construction much like TSA, mediated Akt dephosphory lation in DLBCL DHL 6 cells via elevated bind ing of PP1 to Akt. We more studied the downstream targets from the Akt pathway. Upregulation of p21 was previously generally reported, with less information on p27. Repression of cyclin D1 from HDAC inhibitors was reported in mantle cell lymph oma.. In our research, we identified much more major al terations of p27 and cyclin D1 than p21 right after TSA treatment method. The two p21 and p27 had been upregulated, ...

Of the diverse range of posttranslational modifications of tau (reviewed by us in Chen et al., 2004), serine/threonine-directed phosphorylation and truncations are among the most intensely studied, yet the role of their relative contribution to the tau pathology in Alzheimer disease is not entirely understood. Additional light is shed on them by four recent publications which now appear in JBC (in press). These publications deal with the dephosphorylation of tau by PP5 (Gong and coworkers), Gα12-stimulated PP2A activity and dephosphorylation of tau (Brad Denker and coworkers), thrombin-mediated cleavage of tau (Patrick McGeer and coworkers), and tau phosphorylation and cleavage during apoptosis (Faraj Terro and coworkers). A combination of studies with recombinant proteins, tissue culture experiments and the analysis of human brain section aims to dissect the role of these modifications (and the enzymes responsible for them) under both physiologic and pathologic conditions. As several enzymes ...
