In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Lymphocyte Activation: Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically.

WW: An isolated three-stranded antiparallel beta-sheet domain that unfolds and refolds reversibly; evidence for a structured hydrophobic cluster in urea and GdnHCl and a disordered thermal unfolded state. (1/338)

The objective of this study was to evaluate the suitability of the WW domain as a desirable model system to understand the folding and stability of an isolated three-stranded antiparallel beta-sheet structure. The WW domain was subjected to thermal and chaotropic denaturation/reconstitution utilizing a variety of biophysical methods. This three-stranded sheet folds reversibly and cooperatively utilizing both urea and GdnHCl as denaturants; however, the denatured state retains structure in the form of a hydrophobic cluster involving at least one aromatic side chain. In contrast to chaotropic denaturation, thermal denaturation appears to be more complete and may be a two state process. The suitability of the WW domain for future studies aimed at understanding the kinetics and thermodynamics of antiparallel beta-sheet folding clearly emerges from this initial study. The most exciting and significant result in this manuscript is the finding that the chaotropic denatured state of WW has a hydrophobic cluster as discerned by near-UV CD evidence. The role that the denatured state plays in the folding and stability of a three-stranded beta-sheets, and its capacity for preventing aggregation may be particularly important and is the subject of ongoing studies.  (+info)

Detection of putative Zn(II) binding sites within Escherichia coli RNA polymerase: inconsistency between sequence-based prediction and 65Zn blotting. (2/338)

The availability of repeating 'Cys' and/or 'His' units in a particular order prompts the prediction of Zn(II) finger motifs in a protein. Escherichia coli RNA polymerase has two tightly bound Zn(II) per molecule of the enzyme as detected by atomic absorption spectroscopy. One Zn(II) was identified to be at the beta subunit, whereas the other putative Zn(II) binding site has recently been predicted to be at the N-terminal half of the beta' subunit, from primary sequence analysis. We show here that the beta' subunit has no ability to bind 65Zn(II). On the other hand, the N-terminal domain of the alpha subunit has strong Zn(II) binding ability with no obvious functional implications.  (+info)

Thiopental attenuates hypoxic changes of electrophysiology, biochemistry, and morphology in rat hippocampal slice CA1 pyramidal cells. (3/338)

BACKGROUND AND PURPOSE: Thiopental has been shown to protect against cerebral ischemic damage; however, it has undesirable side effects. We have examined how thiopental alters histological, physiological, and biochemical changes during and after hypoxia. These experiments should enable the discovery of agents that share some of the beneficial effects of thiopental. METHODS: We made intracellular recordings and measured ATP, sodium, potassium, and calcium concentrations from CA1 pyramidal cells in rat hippocampal slices subjected to 10 minutes of hypoxia with and without 600 micromol/L thiopental. RESULTS: Thiopental delayed the time until complete depolarization (21+/-3 versus 11+/-2 minutes for treated versus untreated slices, respectively) and attenuated the level of depolarization at 10 minutes of hypoxia (-33+/-6 versus -12+/-5 mV). There was improved recovery of the resting potential after 10 minutes of hypoxia in slices treated with thiopental (89% versus 31% recovery). Thiopental attenuated the changes in sodium (140% versus 193% of prehypoxic concentration), potassium (62% versus 46%), and calcium (111% versus 197%) during 10 minutes of hypoxia. There was only a small effect on ATP (18% versus 8%). The percentage of cells showing clear histological damage was decreased by thiopental (45% versus 71%), and thiopental improved protein synthesis after hypoxia (75% versus 20%). CONCLUSIONS: Thiopental attenuates neuronal depolarization, an increase in cellular sodium and calcium concentrations, and a decrease in cellular potassium and ATP concentrations during hypoxia. These effects may explain the reduced histological, protein synthetic, and electrophysiological damage to CA1 pyramidal cells after hypoxia with thiopental.  (+info)

Mitotic misregulation and human aging. (4/338)

Messenger RNA levels were measured in actively dividing fibroblasts isolated from young, middle-age, and old-age humans and humans with progeria, a rare genetic disorder characterized by accelerated aging. Genes whose expression is associated with age-related phenotypes and diseases were identified. The data also suggest that an underlying mechanism of the aging process involves increasing errors in the mitotic machinery of dividing cells in the postreproductive stage of life. We propose that this dysfunction leads to chromosomal pathologies that result in misregulation of genes involved in the aging process.  (+info)

Oestrogen, progesterone, and androgen receptors in ovarian neoplasia: correlation between immunohistochemical and biochemical receptor analyses. (5/338)

AIM: To investigate the correlation between immunohistochemical and biochemical steroid receptor analyses by measurement of oestrogen, progesterone, and androgen receptor status in ovarian neoplasia. METHODS: Tissue samples were obtained from 27 ovarian neoplasms, including two borderline tumours. Immunohistochemical staining of the tissue slides was scored semiquantitatively, incorporating the intensity and percentage of positive staining (histo-score). Tumours with a histo-score of 10 or more were considered steroid receptor positive. The epithelial and stromal fractions of the tumours were analysed separately. To study the uniformity of receptor expression throughout a tumour, up to four samples were analysed. RESULTS: Immunohistochemical histo-scores of the oestrogen receptor in the epithelial fractions were significantly correlated with the biochemical oestrogen receptor values (r = 0.408). Androgen receptor status in the epithelial fraction was correlated with that in the stromal fraction (r = 0.741), while androgen receptor histo-scores in the epithelial fraction correlated with the biochemical assay values (r = 0.463). On biochemical analysis, 17 of the 27 ovarian tumours were oestrogen receptor positive and seven were progesterone receptor positive. On immunohistochemical analysis, eight tumours were oestrogen receptor positive and two were progesterone receptor positive. Biochemical analysis showed that 14 of the 26 tumours were slightly androgen receptor positive (10-50 fmol/mg protein), while all the others were negative. On immunohistochemical analysis, seven of the 26 tumours were androgen receptor positive. When two or more specimens from one tumour were analysed, marked differences in steroid status were found, especially in progesterone receptor and androgen receptor expression. Some parts of a tumour were steroid receptor positive, while other parts were negative owing to heterogeneity of expression. CONCLUSIONS: Immunohistochemical and biochemical analysis of steroid receptors in ovarian tumours correlated weakly or not at all. Heterogeneity of expression within a tumour and the presence of progesterone and androgen receptors in the stromal fraction partly accounted for this observation. Biochemical and immunohistochemical androgen receptor status was much lower than in previous reports.  (+info)

Trehalose effect on low temperature protein dynamics: fluctuation and relaxation phenomena. (6/338)

We performed spectral diffusion experiments in trehalose-enriched glycerol/buffer-glass on horseradish peroxidase where the heme was replaced by metal-free mesoporphyrin IX, and compared them with the respective behavior in a pure glycerol/buffer-glass (Schlichter et al., J. Chem. Phys. 2000, 112:3045-3050). Trehalose has a significant influence: spectral diffusion broadening speeds up compared to the trehalose-free glass. This speeding up is attributed to a shortening of the correlation time of the frequency fluctuations most probably by preventing water molecules from leaving the protein interior. Superimposed to the frequency fluctuation dynamics is a relaxation dynamics that manifests itself as an aging process in the spectral diffusion broadening. Although the trehalose environment speeds up the fluctuations, it does not have any influence on the relaxation. Both relaxation and fluctuations are governed by power laws in time. The respective exponents do not seem to change with the protein environment. From the spectral dynamics, the mean square displacement in conformation space can be determined. It is governed by anomalous diffusion. The associated frequency correlation time is incredibly long, demonstrating that proteins at low temperatures are truly nonergodic systems.  (+info)

A new method for mapping nucleic acid sequence homology by electron microscopy. (7/338)

We describe here a new method for the electron microscopic mapping of sequence homology in nucleic acids. Specific segments of the T7 chromosome have been isolated following digestion with the restriction endonuclease from Hemophilus aegyptious (Haey). Denatured segments are annealed to the l-strand of T7 DNA; treatment of the hybrid with glyoxal allows only guanosine residues in the single-chain region to the reacted, producing an adduct which will no longer hydrogen bond with its complement on the r-strand. When the segment is displaced and the glyoxalated l-strand allowed to renature with the r-strand, "H" shaped structures are produced in which the duplex region corresponds to the position of sequence homology with the segment. The conditions employed for glyoxalation do not detectably disrupt duplex regions as small as 400 base pairs. This procedure should be generally useful for observing sequence homology in more complex DNA molecules containing duplex regions which can be specifically enriched for and their arrangement determined by electron microscopy.  (+info)

A novel method to determine the topology of peroxisomal membrane proteins in vivo using the tobacco etch virus protease. (8/338)

Most proteins essential for the biogenesis of peroxisomes (peroxins) that are identified to date are associated with or are integral components of the peroxisomal membrane. A prerequisite in elucidating their function is to determine their topology in the membrane. We have developed a novel tool to analyze the topology of peroxisomal membrane proteins in the yeast Hansenula polymorpha in vivo using the 27-kDa NIa protease subunit from the tobacco etch virus (TEVp). TEVp specifically cleaves peptides containing the consensus sequence, EXXYXQ downward arrowS (tev). We show that cytosolic TEVp and peroxisomal TEVp.SKL are selectively active on soluble cytosolic and peroxisomal tev-containing proteins in vivo, respectively, without affecting the viability of the yeast cells. The tev sequence was introduced in between the primary sequence of the peroxisomal membrane proteins Pex3p or Pex10p and the reporter protein enhanced green fluorescent protein (eGFP). Co-synthesis of these functional tev-GFP tagged proteins with either cytosolic TEVp or peroxisomal TEVp.SKL revealed that the C termini of Pex3p and Pex10p are exposed to the cytosol. Additional applications of the TEV protease to study peroxisome biogenesis are discussed.  (+info)

Westminster-based Myogen Inc.s shares soared Monday after its experimental drug helped patients with a potentially fatal lung disorder in a pivotal trial. A study, one of two needed for U.S. regulatory approval, found that the drug ambrisentan improved patients breathing and slowed worsening of pulmonary arterial hypertension, Myogen said. The once-a-day pill eased shortness of breath, allowing patients to walk farther in a six-minute test, the firm said. Geoffrey Meacham, an analyst at J.P. Morgan Securities Inc., said the results were better than he expected. The findings "clearly position ambrisentan to become a best- in-class oral pulmonary arterial hypertension agent," Meacham wrote in a note to clients. "Myogen remains, in our view, one of the most attractive pipeline stories in biotech," with ambrisentan and the darusentan drug for high blood pressure in development, he said. In the condition that ambrisentan is intended to treat, the pulmonary arteries thicken and become severely ...

Glycoconjugates: Carbohydrates covalently linked to a nonsugar moiety (lipids or proteins).

The forward reaction above is of the pseudo first order, as the professor says. But its rate constant depends on acidic catalytic factors and the net reaction rate is affected by the reverse reaction rate The concentration of products- the organic acid and the alcohol - affects the net reaction rate by increased rate of the reverse reaction and by shifting of the reaction quotient.. The content of a mineral acid catalyzes the reaction, what means speeding up both reactions, therefore keeping the same equilibrium constant.(required as consequence of the energy conservation law). The reaction is still the pseudo first order, but the rate constant depends on concentration of the catalysing acid.. The alternative approach is considering the mineral acid as self-regenerating reagent. But it must be then evaluated as reaction chain.. The content of a mineral base decreases reverse reaction rate and shifts the reaction quotient by reacting with the organic acid. It also directly reacts with the ...
A method for maintaining the attitude of a three-axis controlled satellite by use of magnetic torquers includes using magnetometers for measuring the direction of the ambient geomagnetic field. The direction of the net reaction wheel momentum is also determined. The angle between the direction of the geomagnetic field and the net reaction wheel momentum is determined. The angle is compared with a threshold value. Magnetic torquer power consumption is reduced by operating the magnetic torquers only when the angle exceeds the threshold value.

State-of-the-art biochemical systems for medical applications and chemical computing are application-specific and cannot be re-programmed or trained once fabricated. The implementation of adaptive biochemical systems that would offer flexibility through programmability and autonomous adaptation faces major challenges because of the large number of required chemical species as well as the timing-sensitive feedback loops required for learning. Currently, biochemistry lacks a systems vision on how the user-level programming interface and abstraction with a subsequent translation to chemistry should look like. By developing adaptation in chemistry, we could replace multiple hard-wired systems with a single programmable template that can be (re)trained to match a ...

Biochemistry instructors are inundated with various representations from which to choose to depict biochemical phenomena. Because of the immense amount of visual know-how needed to be an expert biochemist in the 21st century, there have been calls for instructors to develop biochemistry students' visual literacy. However, visual literacy has multiple aspects, and determining which area to develop can be quite daunting. Therefore, the goals of this study were to determine what visual literacy skills biochemistry instructors deem to be most important and how instructors develop and assess visual literacy skills in their biochemistry courses. In order to address these goals, a needs assessment was administered to a national sample of biochemistry faculty at four-year colleges and universities. Based on the results of the survey, a cluster analysis was conducted to group instructors into categories based on how they intended to develop visual literacy in their courses. A

An artificial chemistry is a chemical-like system that usually consists of objects, called molecules, that interact according to rules resembling chemical reaction rules. Artificial chemistries are created and studied in order to understand fundamental properties of chemical systems, including prebiotic evolution, as well as for developing chemical computing systems. Artificial chemistry is a field within computer science wherein chemical reactions-often biochemical ones-are computer-simulated, yielding insights on evolution, self-assembly, and other biochemical phenomena. The field does not use actual chemicals, and should not be confused with either synthetic chemistry or computational chemistry. Rather, bits of information are used to represent the starting molecules, and the end products are examined along with the processes that led to them. The field originated in artificial life but has shown to be a versatile method with applications in many fields such as chemistry, economics, sociology ...
We imaged the purified OT complex by cryo-EM and obtained a first snapshot of the complex by computer reconstruction of the micrographs," said Li, a cryo-EM expert.. In cryo-EM, he explained, samples are frozen in vitreous ice and maintained at cryogenic temperatures (-274° Fahrenheit) using liquid nitrogen while the samples are photographed in the high vacuum of an electron microscope. The sophisticated cryo-EM machine resides in Brookhaven Labs biology department. Li and his collaborators also measured the mass of the OT complex at Brookhavens Scanning Transmission Electron Microscope (STEM) facility.. The structure deciphered by the group helps to explain many biochemical phenomena observed about the enzyme complex over the past two decades. It also offers hints as to how the enzyme performs its various jobs, from recognizing the sugar molecules to be added to the protein, scanning the protein as it is formed to identify the sites where sugars should be attached, and transferring the sugar ...

In a majority of living organisms, FoF1 ATP synthase performs the fundamental process of ATP synthesis. Despite the simple net reaction formula, ADP + Pi. ATP + H2O, the detailed step-by-step mechanism of the reaction yet remains to be resolved owing to the complexity of this multisubunit enzyme. Based on quantum mechanical computations using recent high resolution X-ray structures, we propose that during ATP synthesis the enzyme first prepares the inorganic phosphate for the gamma P-O-ADP bond-forming step via a double-proton transfer. At this step, the highly conserved alpha S344 side chain plays a catalytic role. The reaction thereafter progresses through another transition state (TS) having a planar PO3- ion configuration to finally form ATP. These two TSs are concluded crucial for ATP synthesis. Using stepwise scans and several models of the nucleotide-bound active site, some of the most important conformational changes were traced toward direction of synthesis. Interestingly, as the active site

Biochemistry test refers to the chemical identification of a particular enzyme or protein in bodily fluid samples like blood or urine.
1. Although glycoproteins with less than 1% of sialic acid (fibrinogen, lipoproteins, gamma-globulins) interact electrostatically with chondromucoprotein to form insoluble complexes, interaction with glycoproteins containing larger amounts of sialic acid (orosomucoid, urine glycoprotein, seromucoid, fraction VI) was electrostatically impossible. Reasons for this are discussed. 2. The latter glycoproteins interacted with chondromucoprotein after mild acid hydrolysis or neuraminidase treatment, complex-formation being inversely related to their sialic acid content. 3. Complex-formation with sialic acid-deficient orosomucoid was maximum at pH3.6 and negligible above its isoelectric point of pH5, and was inhibited by Ca(2+) ions and EDTA. 4. These results are discussed in relation to the carbohydrate composition and biological activities of euglobulin fractions, and of complexes formed by adding chondromucoprotein to abnormal plasmas which may contain sialic acid-deficient glycoproteins owing to ...
The analytical goals inferred desirable by a group of clinicians for the imprecisions of a wide range of analytes have been studied by survey. The goals required have not in general become more stringent in the past decade and are not as demanding as those promulgated by laboratory professionals. Clinical biochemistry laboratories can now attain analytical imprecisions which satisfy the general demands of clinicians except for analyses of calcium and of low levels of glucose. The lack of published data on analytical goals does not allow wide comparison of criteria for performance standards with the results of this study.. ...
The permeable rocks of the upper oceanic basement contain seawater-sourced fluids estimated to be ~ 2% of the global ocean volume. This represents a very large potential subsurface biosphere supported by chemosynthesis. Recent collection of high integrity samples of basement fluid from the sedimented young basaltic basement on the Juan de Fuca Ridge flanks, off the coasts of Vancouver Island (Canada) and Washington (USA), and subsequent chemical analyses permit numerical modeling of metabolic redox reaction energetics. Here, values of Gibbs free energy for potential chemolithotrophic net reactions were calculated in basement fluid and in zones where basement fluid and entrained seawater may mix; the energy yields are reported both on a per mole electrons transferred and on a per kg of basement fluid basis. In pure basement fluid, energy yields from the anaerobic respiration processes investigated are anemic, releasing , 0.3 J/kg basement fluid for all reactions except methane oxidation by ferric ...

The identification of kinetic models for multiphase reaction systems is complex due to the simultaneous effect of chemical reactions and mass transfers. The extentbased incremental approach simplifies the modeling task by transforming the reaction system into variant states called vessel extents, one for each rate process. This transformation is carried out from the measured numbers of moles (or concentrations) and requires as many measured species as there are rate processes. Then, each vessel extent can be modeled individually, that is, independently of the other dynamic effects. This paper presents a modified version of the extent-based incremental approach that can be used to identify multiphase reaction systems in the presence of instantaneous equilibria. Different routes are possible depending on the number and type of measured species. The approach is illustrated via the simulated example of the oxidation of benzyl alcohol by hypochlorite in a batch reactor.. ...

Methylation? What exactly is methylation? It is an overlooked, extremely important biochemical reaction and an essential biochemical reaction that takes place in every single cell of our body. Without methylation, we would cease to exist. It is estimated that a billion methylation reactions occur in our bodies every second! It is probably the second most important biochemical reaction in the human body besides oxidative reactions which are responsible for producing energy in our cells. Furthermore, the methylation process in our bodies is interlinked to several other important biochemical reactions. As a matter of fact, you can think of these biochemical pathways as a machine that contains several gears that intermesh with each other. If one gear is not functioning or out of line it effects all the other gears. So, essentially if the methylation cycle or pathway is not working properly it has widespread effects in the function of the body and can have multiple symptoms that go along with this ...

BACKGROUND: Updated National Academy of Clinical Biochemistry (NACB) Laboratory Medicine Practice Guidelines for the use of tumor markers in the clinic have been developed. METHODS: Published reports relevant to use of tumor markers for 5 cancer sites--testicular, prostate, colorectal, breast, and ovarian--were critically reviewed. RESULTS: For testicular cancer, alpha-fetoprotein, human chorionic gonadotropin, and lactate dehydrogenase are recommended for diagnosis/case finding, staging, prognosis determination, recurrence detection, and therapy monitoring. alpha-Fetoprotein is also recommended for differential diagnosis of nonseminomatous and seminomatous germ cell tumors. Prostate-specific antigen (PSA) is not recommended for prostate cancer screening, but may be used for detecting disease recurrence and monitoring therapy. Free PSA measurement data are useful for distinguishing malignant from benign prostatic disease when total PSA is |10 microg/L. In colorectal cancer, carcinoembryonic antigen is
Mass spectrometry (MS) has become an important tool in studying biological systems. One application is the identification of proteins and peptides by the matching of peptide and peptide fragment masses to the sequences of proteins in protein sequence databases. Often prior protein separation of complex protein mixtures by 2D-PAGE is needed, requiring more time and expertise than instructors of large laboratory classes can devote. We have developed an experimental module for our Biochemistry Laboratory course that engages students in MS-based protein identification following protein separation by one-dimensional SDS-PAGE, a technique that is usually taught in this type of course. The module is based on soybean seed storage proteins, a relatively simple mixture of proteins present in high levels in the seed, allowing the identification of the main protein bands by MS/MS and in some cases, even by peptide mass fingerprinting. Students can identify their protein bands using software

The irreducibly complex biochemical systems that I have discussed in this book did not have to be produced recently. It is entirely possible, based simply on an examination of the systems themselves, that they were designed billions of years ago and that they have been passed down to the present by the normal processes of cellular reproduction. Perhaps a speculative scenario will illustrate the point. Suppose that nearly four billion years ago the designer made the first cell, already containing all of the irreducibly complex biochemical systems discussed here and many others. (One can postulate that the designs for systems that were to be used later, such as blood clotting, were present but not turned on. In present-day organisms plenty of genes are turned off for a while, sometimes for generations, to be turned on at a later time.) Additionally. suppose the designer placed into the cell some other systems for which we cannot adduce enough evidence to conclude design. The cell containing the ...

Normal, proliferation-competent cells may monitor their environment and react properly to perturbation accurately, whether its a lack of neighbours or an inflammatory stimulus. Tumor cells either proliferate or wont perish where so when they ought never to, which obviously indicates they have problems in responding or detecting with their environment. Thus, a massive amount of work has truly gone into determining the signaling pathways that may cause a proliferative response as well as the biochemical systems root these pathways. Much less function has centered on understanding the higher-order reasoning of the pathways as well as the jobs played by every one of the components within an integrated program. Quite simply, we usually do not actually know how cells procedure details and make decisions and therefore cannot anticipate how any provided molecular modification will alter what a cell does.

TY - JOUR. T1 - Rapid conversion of glycerol to lactic acid under alkaline hydrothermal conditions, by using a continuous flow reaction system. AU - Shimanouchi, Toshinori. AU - Ueno, Shouhei. AU - Shidahara, Kazuki. AU - Kimura, Yukitaka. PY - 2014. Y1 - 2014. N2 - A rapid conversion of glycerol to lactic acid (lactate) could be successfully achieved under alkaline hydrothermal conditions, by using a continuous flow reaction system. A rapid conversion by a continuous flow-type reaction system made it possible to achieve the reaction under high-temperature conditions without side reactions. The rapid conversion and high reaction yield (reaction: 2min; yield: 90%) resulted from the rapid temperature-shift advantageous for the inhibition of side reactions..

A rapid conversion by a continuous flow-type reaction system made it ...
To see the link with the standard DEB model (with which most contributions in this issue deal), it helps to realize that DEB models for dividing unicellular organisms represent both a simplification and an extension. Biomass is (formally) partitioned into one structure and a number of reserves that is typically equal to the types of substrates (CQ nutrients) that are taken up independently from the environment; substrates are converted to reserves and mobilized reserves are used for all other metabolic needs (maintenance, growth, maturation). The metabolic pools (reserves, structure) are supposed to have a constant chemical composition (strong homeostasis). Cells growing in (chemically) constant environments do not change in composition (weak homeostasis). The requirement for weak homeostasis fully specifies the mobilization fluxes (Sousa et al. 2008). After subtraction of the reserve-specific somatic maintenance costs, the remaining fluxes are converted to structure using the merging rules of ...
