Review: The group II metabotropic glutamate receptor 3 (mGluR3, mGlu3, GRM3): expression, function and involvement in schizophrenia (2008)

Group II metabotropic glutamate receptors (mGluRs) comprise mGluR2 (mGlu2; encoded by GRM2) and mGluR3 (mGlu3; encoded by GRM3) and modulate glutamate neurotransmission and synaptic plasticity. Here we review the expression and function of mGluR3 and its involvement in schizophrenia. mGluR3 is expressed by glia and neurons in many brain regions and has a predominantly presynaptic distribution, consistent with its role as an inhibitory autoreceptor and heteroceptor. mGluR3 splice variants exist in human brain but are of unknown function. Differentiation of mGluR3 from mGluR2 has been problematic because of the lack of selective ligands and antibodies; the available data suggest particular roles for mGluR3 in long-term depression, in glial function and in neuroprotection. Some but not all studies find genetic association of GRM3 polymorphisms with psychosis, with the risk alleles also being associated with schizophrenia-related endophenotypes such as impaired cognition, cortical activation and glutamate markers. The dimeric form of mGluR3 may be reduced in the brain in schizophrenia. Finally, preclinical findings have made mGluR3 a putative therapeutic target, and now direct evidence for antipsychotic efficacy of a group II mGluR agonist has emerged from a randomised clinical trial in schizophrenia. Together these data implicate mGluR3 in aetiological, pathophysiological and pharmacotherapeutic aspects of the disorder.
BHLH transcription factor DEC2 regulates pro-apoptotic factor Bim in human oral cancer HSC-3 cells (2012)

DEC1 (BHLHE40/Stra13/Sharp2) and DEC2 (BHLHE41/Sharp1) are basic helix-loop-helix (bHLH) transcription factors that are involved in the regulation of apoptosis, cell proliferation, circadian rhythms and the response to hypoxia. We previously showed the functional effects of DEC1 and DEC2 on apoptosis in human breast cancer MCF-7 cells. However, the roles of DEC1 and DEC2 in oral cancer are poorly understood. We examined whether DEC1 and DEC2 are involved in the regulation of apoptosis in human oral cancer HSC-3 and CA9-22 cells. The expression of DEC2 was upregulated by cis-diamminedichloroplatinum (II) (cisplatin: CDDP) treatment in HSC-3 cells, whereas CDDP treatment had little effects on the expression of DEC2 in CA9-22 cells. We showed that DEC2 overexpression inhibits pro-apoptotic factor Bim and inhibits apoptosis induced by CDDP in HSC-3 cells, whereas it had little effects on apoptosis in CA9-22 cells. DEC1 overexpression had little effects on apoptosis induced by CDDP in these cells. We also found that CDDP upregulated the amounts of DEC2 in the nucleus in HSC-3 cells. These results suggest that DEC2 has anti-apoptotic effects on apoptosis induced by CDDP in HSC-3 cells.
Responses of thoracic spinothalamic and spinoreticular cells to coronary artery occlusion (1984)

Spinothalamic and spinoreticular neurons in the C8-T5 spinal segments were examined for responsiveness to occlusion of the left main, left circumflex (CX), or left anterior descending (LAD) coronary artery in monkeys and cats. Four types of cell response to occlusion were observed, as follows: 1) cell activity increased (6 responses) or decreased (1 response) to myocardial ischemia produced by the occlusion; 2) cell activity increased at the onset of occlusion, adapted, and then increased again as ischemia developed (6 responses); 3) cell activity increased at the onset or release of occlusion, and rapidly adapted (13 responses) or remained elevated throughout the occlusion (2 responses); and 4) no response to occlusion (14 tests). Among the types of responses to occlusion, both the magnitude of increased cell activity as well as the spontaneous discharge rates were similar. There were no differences in types of response according to coronary artery ligated. Fourteen cells were tested for responses to separate occlusions of the LAD and CX. Ten cells responded differently to the two occlusions, and four cells exhibited similar responses. C-fiber input onto a neuron was significantly related to whether a cell exhibited a response to cardiac ischemia. Since every cell with C-fiber input did not respond to ischemia, however, this input was not sufficient to predict whether a cell would respond to ischemia. All cells had somatic fields, and all cells responded to noxious stimulation of the somatic field. Some cells also received input from hair movement. The modality of the effective somatic stimulus was not related to type of response to coronary artery occlusion. Spinothalamic and spinoreticular neurons responded similarly to occlusion. Type of response was neither related to cell location in spinal cord nor to projection site in brain. We conclude that spinothalamic and spinoreticular neurons respond to coronary artery occlusion. Different neurons may receive input from different regions of the heart as well as from different types of visceral afferents, resulting in various responses to occlusion. The population of cells excited from ischemia of a given portion of myocardium may determine how the brain interprets the noxious information and refers pain to different somatic structures.

High osteopontin levels predict long-term outcome after STEMI and primary percutaneous coronary intervention (2013)

In conclusion, a high OPN level, especially in combination with a high hsCRP level, was associated with poor long-term outcome in STEMI patients treated with pPCI.
[Eimeria tenella cDNA library construction and expressed sequence tags analysis]. (2007)

In order to make a series of analyses on the gene expression of Eimeria tenella sensitive strain and anti-maduramycin strain at their different developmental stages, we constructed a mixed cDNA library with unsporulated oocyst, sporulated oocyst, sporozoite and merozoite from Eimeria tenella sensitive strain and antimaduramycin strain (induced by its sensitive strain)respectively. After sequencing reactions, the total 2806 high quality expressed sequence tags (ESTs) of 3' ends were derived from the cDNA library. Results of bioinformatics analysis of all EST data showed that EST sequences assembled 1424 tentative unique transcripts (TUTs) and the redundancy was 49.3%, and that about 83.6% TUTs could not be assigned for functional description. Among the remained annotated genes, infection related proteins and development related proteins such as MIC2 protein, BT1 family protein and some ribosomal protein expressed at high abundant level.
mTOR Signaling and the Molecular Adaptation to Resistance Exercise (2006)

Skeletal muscle size is dynamic and responsive to extracellular signals such as mechanical load, neural activity, hormones, growth factors, and cytokines. The signaling pathways responsible for regulating cell size in adult skeletal muscle under growth and atrophy conditions are poorly understood. However, recent evidence suggests a role for the PI3K/Akt/mTOR pathway. Protein translation is regulated through the phosphorylation of initiation factors that are controlled by signaling pathways downstream of PI3K/Akt. Recent work in mammals has suggested that activation of Akt/PKB, a Ser-Thr phosphatidylinositol-regulated kinase, and its downstream targets, glycogen synthase kinase-3 (GSK3) and the mammalian target of rapamycin (mTOR), may be critical regulators of postnatal cell size in multiple organ systems, including skeletal muscle. This paper will review some of the recent data that demonstrate the critical role of Akt/mTOR signaling in the regulation of postnatal muscle size, especially under conditions of increased external loading.
Conserved Arrangement of Nested Genes at the Drosophila Gart Locus (1987)

The Drosophila melanogaster Gart gene encodes three enzymatic activities in the pathway for purine de novo synthesis. Alternative processing of the primary transcript leads to the synthesis of two overlapping polypeptides. The coding sequence for both polypeptides is interrupted by an intron that contains a functional cuticle protein gene encoded on the opposite DNA strand. Here we show that this nested organization also exists at the homologous locus of a distantly related species, Drosophila pseudoobscura. In both species, the intronic cuticle gene is expressed in wandering larvae and in prepupae. Remarkably, there are 24 different highly conserved noncoding segments within the intron containing the cuticle gene. These are found upstream of the transcriptional start, at the 3' end, and even within the single intronic gene intron. Other introns in the purine gene, including the intron at which alternative processing occurs, show no such homologies. It seems likely that at least some of the conserved noncoding regions are involved in specifying the high level developmental expression of the cuticle gene. We discuss the possibility that shared cis-acting regulatory sites might enhance transcription of both genes and help explain their nested arrangement.
Use of topical corticosteroid pretreatment to reduce the incidence and severity of skin reactions associated with testosterone transdermal therapy (1998)

Local skin reactions at the application site are the most common adverse events associated with the testosterone transdermal delivery (TTD) systems used to treat postpubertal hypogonadism in males. This open-label, controlled pilot study was conducted to determine whether topical pretreatment with triamcinolone acetonide 0.1% cream might be useful in reducing the incidence and/or severity of chronic skin irritation when used in healthy volunteers receiving TTD systems. Adult male volunteers wore three topical systems, which were applied to the upper back daily (Monday through Friday) for 6 weeks: (1) TTD with no pretreatment of application site; (2) TTD with pretreatment of application site using triamcinolone acetonide 0.1% cream; and (3) an inactive occlusive dressing (control). On Monday through Thursday, systems were removed 24 hours after application. Patches applied on Friday were worn continuously for 72 hours until their removal on Monday. Skin reactions were graded on a scale from 0 to 4 (0 = none, 4 = severe) and were assessed daily by research personnel, beginning at the time of system removal (assessment 1) and on the two subsequent clinic visits (assessments 2 and 3). All skin irritation scores of all subjects were totaled for each treatment regimen to obtain a cumulative score per treatment regimen. The cumulative scores were also analyzed by assessment time and study week (weeks 1-6). Eighty-two subjects were enrolled in the study, and 65 completed the 6-week treatment course. Mean age of subjects was 24 years (range, 18-69 years), and mean weight was 79.0 kg (range, 58.9-127.3 kg). All subjects were white males. At assessment 1, pretreatment with triamcinolone acetonide 0.1% cream (compared with no pretreatment) was associated more often with scores of 0 (no erythema), with comparable occurrences of mild skin irritation, and with fewer occurrences of moderate erythema. At all three assessments, more subjects had lower cumulative scores with pretreatment than without pretreatment. At every assessment and in each week of the study, total weekly cumulative skin irritation scores were also lower with pretreatment than without pretreatment. No adverse experiences other than skin irritation were reported. Results of this study suggest that in patients using TTD systems, the incidence and severity of skin irritation at application sites may be reduced through pretreatment with triamcinolone acetonide 0.1% cream.
Near‐Infrared Light‐Triggered, Targeted Drug Delivery to Cancer Cells by Aptamer Gated Nanovehicles (2012)

A novel cell-targeting, near-infrared light-responsive drug delivery platform based on mesoporous silica-coated gold nanorods that are surface-functionalized with aptamer DNA is constructed. Aptamer DNA is used as both capping and targeting agent. In vitro studies show the feasibility of using this nanocarrier for targeted and noninvasive remote controlled drug delivery and photothermal therapy.
Effect of primary structure modifications in Trypanosoma cruzi neuraminidase/trans-sialidase activities. (1996)

Neuraminidases have been implicated in various processes involving the interaction of pathogens and their receptor cells. Trypanosoma cruzi, the agent of Chagas disease, has an unusual neuraminidase, able to transfer bound alpha(2-3)sialic acid to a suitable acceptor rather than to water: the trans-sialidase (TcTS). This enzyme is encoded by a family of several homologous genes, some of them rendering inactive the products. We have shown that enzymatically active proteins have Tyr in position 342, whereas inactive TcTS contain a His342. We have now mutated this Tyr residue to Phe or Thr. Both mutant proteins resulted in enzymatically inactive products. Chimeras expressing parts of Salmonella typhimurium neuraminidase (NANH) and TcTS were constructed. Only the construct containing the complete NANH molecule fused to the last 272 residues of TcTS had neuraminidase activity. However this construct did not present TcTS activity. This finding suggests that other residues present in the homology region are required for TcTS activity.
A Yeast Gene That Is Essential for Release from Glucose Repression Encodes a Protein Kinase (1986)

The SNF1 gene plays a central role in carbon catabolite repression in the yeast Saccharomyces cerevisiae, namely that SNF1 function is required for expression of glucose-repressible genes. The nucleotide sequence of the cloned SNF1 gene was determined, and the predicted amino acid sequence shows that SNF1 encodes a 72,040-dalton polypeptide that has significant homology to the conserved catalytic domain of mammalian protein kinases. Specific antisera were prepared and used to identify the SNF1 protein. The protein was shown to transfer phosphate from adenosine triphosphate to serine and threonine residues in an in vitro autophosphorylation reaction. These findings indicate that SNF1 encodes a protein kinase and suggest that protein phosphorylation plays a critical role in regulation by carbon catabolite repression in eukaryotic cells.

Band discontinuities at epitaxial SrTiO3/Si(001) heterojunctions (2000)

We have used photoemission methods to directly measure the valence and conduction band offsets at SrTiO3/Si(001) interfaces, as prepared by molecular-beam epitaxy. Within experimental error, the measured values are the same for growth on n- and p-Si, with the entire band discontinuity occurring at the valence band edge. In addition, band bending is much larger at the p-Si heterojunction than at the n-type heterojunction. Previously published threshold voltage behavior for these interfaces can now be understood in light of the present results.
Causal analytical wavelet transform (1992)

The causal analytical wavelet transform employs exponentially decaying nonsinusoidal wideband transient bases of compact support. The basis set <i>h<sub>ab</sub></i>(<i>t</i>) = <i>h</i>[(<i>t</i>- <i>b</i>)/<i>a</i>]√<i>a</i> is called daughter wavelets, which are constructed from a causal analytical mother wavelet <i>h</i>(<i>t</i>) by means of the dilation parameter <i>a</i> and the translation parameter <i>b</i>. We show that a causal (i.e., zero valued before signal arrives) and analytical mother wavelet still guarantees completeness. This permits the selection of mother wavelets that better match causal analytical input signals. An optical architecture is described for real-time implementation.
Characterization of heparan sulphate 3-O-sulphotransferase isoform 6 and its role in assisting the entry of herpes simplex virus type 1 (2005)

Heparan sulphate (HS) 3-O-sulphotransferase transfers sulphate to the 3-OH position of the glucosamine residue of HS to form 3-O-sulphated HS. The HS modified by 3-O-sulphotransferase isoform 3 binds to HSV-1 (herpes simplex virus type 1) gD (envelope glycoprotein D), and the resultant 3-O-sulphated HS serves as an entry receptor for HSV-1. In the present paper, we report the isolation and characterization of a novel HS 3-O-sulphotransferase isoform, designated HS 3-O-sulphotransferase isoform 6 (3-OST-6). Mouse 3-OST-6 gene was identified in the EST (expressed sequence tag) database and cloned into pcDNA3.1/Myc-His vector. A CHO (Chinese-hamster ovary) cell line that stably expresses 3-OST-6 (3OST6/CHO cells) was prepared. The disaccharide analysis of the HS isolated from 3OST6/CHO cells revealed that 3-OST-6 exhibits HS 3-O-sulphotransferase activity. Furthermore, 3OST6/CHO cells were susceptible to infection by HSV-1, but not by other alphaherpesviruses examined, suggesting that 3-OST-6 produces a specific entry receptor for HSV-1. Our results indicate that a new member of 3-OST family generates an entry receptor for HSV-1. The findings add to the growing body of evidence that HSV-1 entry is mediated by 3-O-sulphated HS generated by multiple members of 3-O-sulphotransferases.
Recombinant Angiotensin-Converting Enzyme 2 Suppresses Pulmonary Vasoconstriction in Acute Hypoxia (2012)

In acute pulmonary hypertension, administration of ACE2 blunts the rise in pulmonary arterial pressure that occurs in response to hypoxia. Recombinant ACE2 may be a treatment option for high altitude pulmonary edema and hypoxia-associated pulmonary hypertension.
Traveling-wave photodetectors (1992)

The authors propose and analyze the traveling-wave photodetector (TWPD), an edge-coupled photodetector that is capable of both a larger absolute bandwidth and a larger bandwidth-efficiency product than the waveguide photodetector (WGPD). The intrinsic RC bandwidth limitation is increased in the traveling-wave photodetector by providing for controlled transmission of the electrical wave down the device in parallel with the optical wave and by eliminating bandwidth-limiting electrical reflections. It is shown that 1- mu m wide, parallel-plate, GaAs/AlGaAs, p-i-n TWPD with open-circuit input termination has a 26% greater potential bandwidth-efficiency product than the comparable WGPD, while a TWPD with matched input termination actually has a worse bandwidth-efficiency product than the WGPD.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Promotion of central nervous system remyelination by induced differentiation of oligodendrocyte precursor cells (2009)

Our studies demonstrate that LINGO-1 antagonism promotes OPC differentiation and remyelination, and suggest LINGO-1 functions as an inhibitor of OPC differentiation to retard central nervous system remyelination.
Thin Film Lubrication of Real Surfaces (1998)

When rolling bearings and gears are lubricated with a clean lubricant the initial metal to metal contact through the oil film will normally stop in less than a million loading cycles if the surfaces are at all able to run-in. If, after the running-in, the temperature is increased or the speed is decreased, metallic contact through the oil film will start again and continue until the surfaces have run in again at the new running conditions. The running-in continues as long as some asperities reach each other through the oil film, and the run-in state is characterized by the minimum separation between the highest roughness tops being very close to zero.
MIRD pamphlet No. 17: the dosimetry of nonuniform activity distributions--radionuclide S values at the voxel level. Medical Internal Radiation Dose Committee. (1999)

The availability of quantitative three-dimensional in vivo data on radionuclide distributions within the body makes it possible to calculate the corresponding nonuniform distribution of radiation absorbed dose in body organs and tissues. This pamphlet emphasizes the utility of the MIRD schema for such calculations through the use of radionuclide S values defined at the voxel level. The use of both dose point-kernels and Monte Carlo simulation methods is also discussed. PET and SPECT imaging can provide quantitative activity data in voxels of several millimeters on edge. For smaller voxel sizes, accurate data cannot be obtained using present imaging technology. For submillimeter dimensions, autoradiographic methods may be used when tissues are obtained through biopsy or autopsy. Sample S value tabulations for five radionuclides within cubical voxels of 3 mm and 6 mm on edge are given in the appendices to this pamphlet. These S values may be used to construct three-dimensional dose profiles for nonuniform distributions of radioactivity encountered in therapeutic and diagnostic nuclear medicine. Data are also tabulated for 131I in 0.1-mm voxels for use in autoradiography. Two examples illustrating the use of voxel S values are given, followed by a discussion of the use of three-dimensional dose distributions in understanding and predicting biologic response.
