This technique is useful for studying interactions of molecules and PROTEIN FOLDING.Energy Transfer: The transfer of energy of a given form among different scales of motion. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed). It includes the transfer of kinetic energy and the transfer of chemical energy. The transfer of chemical energy from one molecule to another depends on proximity of molecules so it is often used as in techniques to measure distance such as the use of FORSTER RESONANCE ENERGY TRANSFER.Luciferases, Renilla: Luciferases from RENILLA that oxidizes certain LUMINESCENT AGENTS to cause emission of PHOTONS.Luminescent Measurements: Techniques used for determining the values of photometric parameters of light resulting from LUMINESCENCE.Renilla: A genus of bioluminescent marine invertebrates in the family Renillidae, order Pennatulacea, class ANTHOZOA. It contains Renilla LUCIFERASE which oxidizes coelenterazine resulting in LUMINESCENCE.Luminescence: Emission of LIGHT when ELECTRONS return to the electronic ground state from an excited state and lose the energy as PHOTONS. It is sometimes called cool light in contrast to INCANDESCENCE. LUMINESCENT MEASUREMENTS take advantage of this type of light emitted from LUMINESCENT AGENTS.Luminescent Proteins: Proteins which are involved in the phenomenon of light emission in living systems.

Gene transfer may result in genetically transformed cells and individual organisms.Cell Line: Established cell cultures that have the potential to propagate indefinitely.Recombinant Fusion Proteins: Recombinant proteins produced by the GENETIC TRANSLATION of fused genes formed by the combination of NUCLEIC ACID REGULATORY SEQUENCES of one or more genes with the protein coding sequences of one or more genes.Biosensing Techniques: Any of a variety of procedures which use biomolecular probes to measure the presence or concentration of biological molecules, biological structures, microorganisms, etc., by translating a biochemical interaction at the probe surface into a quantifiable physical signal.GTP-Binding Protein alpha Subunits, Gi-Go: A family of heterotrimeric GTP-binding protein alpha subunits that were originally identified by their ability to inhibit ADENYLYL CYCLASES. Members of this family can couple to beta and gamma G-protein subunits that activate POTASSIUM CHANNELS. The Gi-Go part of the name is also spelled Gi/Go.Quantum Dots: Nanometer sized fragments of semiconductor crystalline material which emit PHOTONS. The wavelength is based on the quantum confinement size of the dot. They can be embedded in MICROBEADS for high throughput ANALYTICAL CHEMISTRY TECHNIQUES.COS Cells: CELL LINES derived from the CV-1 cell line by transformation with a replication origin defective mutant of SV40 VIRUS, which codes for wild type large T antigen (ANTIGENS, POLYOMAVIRUS TRANSFORMING). They are used for transfection and cloning. (The CV-1 cell line was derived from the kidney of an adult male African green monkey (CERCOPITHECUS AETHIOPS).)Receptors, Adrenergic, beta-2: A subclass of beta-adrenergic receptors (RECEPTORS, ADRENERGIC, BETA). The adrenergic beta-2 receptors are more sensitive to EPINEPHRINE than to NOREPINEPHRINE and have a high affinity for the agonist TERBUTALINE.

Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed)Protein Structure, Tertiary: The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.Signal Transduction: The intracellular transfer of information (biological activation/inhibition) through a signal pathway. 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.Protein Structure, Quaternary: The characteristic 3-dimensional shape and arrangement of multimeric proteins (aggregates of more than one polypeptide chain).Cell Membrane: The lipid- and protein-containing, selectively permeable membrane that surrounds the cytoplasm in prokaryotic and eukaryotic cells.Protein Conformation: The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).Immunoprecipitation: The aggregation of soluble ANTIGENS with ANTIBODIES, alone or with antibody binding factors such as ANTI-ANTIBODIES or STAPHYLOCOCCAL PROTEIN A, into complexes large enough to fall out of solution.Protein Transport: The process of moving proteins from one cellular compartment (including extracellular) to another by various sorting and transport mechanisms such as gated transport, protein translocation, and vesicular transport.Embryo Transfer: The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.Fluorescent Dyes: Agents that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.Bacterial Proteins: Proteins found in any species of bacterium.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Radioligand Assay: Quantitative determination of receptor (binding) proteins in body fluids or tissue using radioactively labeled binding reagents (e.g., antibodies, intracellular receptors, plasma binders).Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Cyclic AMP: An adenine nucleotide containing one phosphate group which is esterified to both the 3'- and 5'-positions of the sugar moiety. It is a second messenger and a key intracellular regulator, functioning as a mediator of activity for a number of hormones, including epinephrine, glucagon, and ACTH.CHO Cells: CELL LINE derived from the ovary of the Chinese hamster, Cricetulus griseus (CRICETULUS). The species is a favorite for cytogenetic studies because of its small chromosome number. The cell line has provided model systems for the study of genetic alterations in cultured mammalian cells.Luciferases, Firefly: Luciferases from FIREFLIES, usually Photinus, that oxidizes FIREFLY LUCIFERIN to cause emission of PHOTONS.Endocytosis: Cellular uptake of extracellular materials within membrane-limited vacuoles or microvesicles. ENDOSOMES play a central role in endocytosis.Receptor, PAR-1: A thrombin receptor subtype that couples to HETEROTRIMERIC GTP-BINDING PROTEINS resulting in the activation of a variety of signaling mechanisms including decreased intracellular CYCLIC AMP, increased TYPE C PHOSPHOLIPASES and increased PHOSPHOLIPASE A2.Receptor, PAR-2: A G-protein-coupled, proteinase-activated receptor that is expressed in a variety of tissues including ENDOTHELIUM; LEUKOCYTES; and the GASTROINTESTINAL TRACT. The receptor is activated by TRYPSIN, which cleaves off the N-terminal peptide from the receptor. The new N-terminal peptide is a cryptic ligand for the receptor. The uncleaved receptor can also be activated by the N-terminal peptide present on the activated THROMBIN RECEPTOR and by small synthetic peptides that contain the unmasked N-terminal sequence.

Proteins are the elementary machinery of life, and their functions are carried out mostly by molecular interactions. Among those interactions, protein-protein interactions (PPIs) are the most important as they participate in or mediate all essential biological processes. However, many common methods for PPI investigations are slightly unreliable and suffer from various limitations, especially in the studies of dynamic PPIs. To solve this problem, a method called Bioluminescence Resonance Energy Transfer (BRET) was developed about seventeen years ago. Since then, BRET has evolved into a whole class of methods that can be used to survey virtually any kinds of PPIs. Compared to many traditional methods, BRET is highly sensitive, reliable, easy to perform, and relatively inexpensive. However, most importantly, it can be done in vivo and allows the real-time monitoring of dynamic PPIs with the easily detectable light signal, which is extremely valuable for the PPI functional research. This review will take a
The mild neuroinflammation hypothesis of schizophrenia was introduced by Bechter in 2001.It has been hypothesized that a hypofunction of glutamatergic signaling via N-methyl-n-aspartate receptors (NMDARs) and hyperactivation of dopamine D2 receptors play a role in schizophrenia. The triplet puzzle theory states that sets of triplet amino acid homologies guide two different receptors towards each other and contributes to the formation of a receptor heteromer. It is therefore proposed that putative NMDAR- C-C chemokine receptor type 2 (CCR2), NMDAR- C-X-C chemokine receptor type 4 (CXCR4) and NMDAR- Interleukin 1 receptor type II (IL1R2) heteromers can be formed in the neuronal networks in mild neuroinflammation due to demonstration of Gly-Leu-Leu (GLL), Val-Ser-Thr (VST) and/or Ser-Val-Ser (SVS) amino acid homologies between these receptor protomers. This molecular process may underlie the ability to produce symptoms of schizophrenia in mild neuroinflammation. In this state volume transmission is
G protein-coupled receptors (GPCRs) are well recognized as being able to activate several signaling pathways through the activation of different G proteins as well as other signaling proteins such as beta-arrestins. Therefore, understanding how such multiple GPCR-mediated signaling can be integrated constitute an important aspect. Here, we applied bioluminescence resonance energy transfer (BRET) to shed more light on the G protein coupling profile of trypsin receptor, or protease-activated receptor 2 (PAR2), and its interaction with beta-arrestin1. Using YFP and Rluc fusion constructs expressed in COS-7 cells, BRET data revealed a pre-assembly of PAR2 with both Galphai1 and Galphao and a rapid and transient activation of these G proteins upon receptor activation. In contrast, no preassembly of PAR2 with Galpha12 could be detected and their physical association can be measured with a very slow and sustained kinetics similar to that of beta-arrestin1 recruitment. These data demonstrate the coupling of
Bioluminescence resonance energy transfer (BRET) is a well-established method for investigating protein-protein interactions. Here we present a BRET approach to monitor ligand binding to G protein-coupled receptors (GPCRs) on the surface of living cells made possible by the use of fluorescent ligands in combination with a bioluminescent protein (NanoLuc) that can be readily expressed on the N terminus of GPCRs.. ...
V. Viviani et al. [Biochemistry 38 (1999) 8271] were the first to succeed in cloning the red-emitting enzyme from the South American railroad worm, which is the only bioluminescent organism known to emit a red-colored light. The application of red bioluminescence has been our goal because the transmittance of longer-wavelength light is superior to that of the other colors for visualization of biological functions in living cells. Now, different color luciferases, which emit with wavelength maxima ranging from 400 to 630 nm, are available and are being used. For example, based on different color luciferases, Nakajima et al. developed a tricolor reporter in vitro assay system based on these different color luciferases in which the expression of three genes can be monitored simultaneously. On the other hand, bioluminescence resonance energy transfer (BRET) is a natural phenomenon caused by the intermolecular interaction between a bioluminescent protein and a fluorophore on a second protein, ...
Bouvier also pioneered the use of bioluminescence resonance energy transfer (BRET) for the study of protein-protein interactions and signalling activity in living cells. In addition to the development of screening assays that are now used for drug discovery, this methodology revealed the oligomeric nature of GPCRs and the role of higher order protein complexes in the spatio-temporal regulation of signal transduction under normal and pathological conditions. These tools and new concepts provide the foundation to elucidate how the macromolecular architecture and arrangement of signalling molecules provide the selectivity and fidelity to assure the appropriate propagation of information in cells ...
Adrenergic receptors (ARs) mediate the physiological effects of epinephrine and norepinephrine. There are nine AR subtypes, with three subfamilies (α1, α2, and β) comprised of three subtypes each. These receptors are Family A (rhodopsin-like) GPCRs, in contrast to the GABAB and T1R taste receptors, which belong to GPCR Family C. β2AR is the most widely-expressed AR subtype and was the focus of a number of early studies that provided key evidence in support of the notion of GPCR dimerization. β2AR homodimerization has been demonstrated via 1) coimmunoprecipitation of differentially tagged versions of the receptor (Hebert et al., 1996), 2) functional studies demonstrating rescue of a constitutively desensitized form of the receptor (Hebert et al., 1998), and 3) bioluminescence resonance energy transfer between versions of the receptor with distinct fluorescent proteins fused to the cytoplasmic carboxyl-termini (Angers et al., 2000). More recent work has demonstrated that mutation of a ...
Understanding the component stoichiometry of the T cell antigen receptor (TCR) triggering apparatus is essential for building realistic models of signal initiation. Recent studies suggesting that the TCR and other signaling-associated proteins are preclustered on resting T cells relied on measurements of the behavior of membrane proteins at interfaces with functionalized glass surfaces. Using fluorescence recovery after photo-bleaching, we show that, compared with the apical surface, the mobility of TCRs is significantly reduced at Jurkat T cell/glass interfaces, in a signaling-sensitive manner. Using two biophysical approaches that mitigate these effects, bioluminescence resonance energy transfer and two-color coincidence detection microscopy, we show that, within the uncertainty of the methods, the membrane components of the TCR triggering apparatus, i.e. the TCR complex, MHC molecules, CD4/Lck and CD45, are exclusively monovalent or monomeric in human T cell lines, implying that TCR ...
Nanoparticles have been extensively used for inflammation imaging and photodynamic therapy of cancer. However, the major translational barriers to most nanoparticle-based imaging and therapy applications are the limited depth of tissue penetration, inevitable requirement of external irradiation, and poor biocompatibility of the nanoparticles. To overcome these critical limitations, we synthesized a sensitive, specific, biodegradable luminescent nanoparticle that is self-assembled from an amphiphilic polymeric conjugate with a luminescent donor (luminol) and a fluorescent acceptor [chlorin e6 (Ce6)] for in vivo luminescence imaging and photodynamic therapy in deep tissues. Mechanistically, reactive oxygen species (ROS) and myeloperoxidase generated in inflammatory sites or the tumor microenvironment trigger bioluminescence resonance energy transfer and the production of singlet oxygen (1O2) from the nanoparticle, enabling in vivo imaging and cancer therapy, respectively. This self-illuminating ...
Bret Michaels will return to the stage tonight, much to the delight of his fans worldwide -- but weve learned his doctor is not crazy about the comeback…
A heteroreceptor is a receptor regulating the synthesis and/or the release of mediators other than its own ligand. Heteroreceptors are receptors that respond to neurotransmitters, neuromodulators, or neurohormones released from adjacent neurons or cells; they are opposite to autoreceptors, which are sensitive only to neurotransmitters or hormones released by the cell in whose wall they are embedded. Norepinephrine can influence the release of acetylcholine from parasympathetic neurons by acting on α2 adrenergic (α2A, α2B, and α2C) heteroreceptors. Acetylcholine can influence the release of norepinephrine from sympathetic neurons by acting on muscarinic-2 and muscarinic-4 heteroreceptors. CB1 negatively modulates the release of GABA and glutamate, playing a crucial role in maintaining a homeostasis between excitatory and inhibitory transmission. Glutamate released from an excitatory neuron escapes from the synaptic cleft and preferentially affects mGluR III receptors on the presynaptic ...

CB1 receptor je presinaptički heteroreceptor koji moduliše otpuštanje neurotransmitera kad je aktiviran. On funkcioniše na način koji je zavistan od doze, stereoselektivan i senzitivan na pertuzijski toksin.[3] CB1 receptor aktiviraju kanabinoidi, prirodno formirani u telu (Endokanabinoidi) ili uneseni kao kanabis ili srodno sintetičko jedinjenje.. Iz istraživanja proizilazi da je većina CB1 receptora spregnuta sa Gi/o proteinima. Pri aktivaciji, CB1 receptor deluje prvenstveno putem aktivacije Gi, čime se snižava intracelularna cAMP koncentracija putem inhibicije enzima za njegovu produkciju, adenilat ciklaze, i povišava koncentracija mitogenom-aktivirane proteinske kinaze (MAP kinaze). Alternativno, u nekim retkim slučajevima aktivacija CB1 receptora može da bude spregnuta sa Gs proteinima, koji stimulišu adenilat ciklazu.[2] Poznato je da cAMP služi kao sekundarni glasnik koji se spreže sa mnoštvom jonskih kanala, uključujući unutrašnje ispravljajuće kalijumske kanale ...

Insulin receptor substrates (IRS)-5 and -6 are two recently identified members of the IRS family. We investigated their roles as insulin receptor substrates and compared them with Src-homology-2-containing (Shc) protein, a well-established substrate. Bioluminescence resonance energy transfer (BRET) experiments showed no interaction between the receptor and IRS-5, while interaction with IRS-6 was not enhanced by insulin. By contrast, Shc showed an insulin-induced BRET response, as did a truncated form of IRS-1 (1-262). While Shc was heavily phosphorylated after stimulation of the insulin receptor, IRS-5 and -6 showed very weak phosphorylation levels. These results suggest that, although these two adaptors have previously been proposed as substrates for the insulin receptor, they are poor substrates for the insulin receptor. This calls into question their relevance to insulin signalling.
Green fluorescent proteins (GFPs) and calcium-activated photoproteins of the aequorin/clytin family, now widely used as research tools, were originally isolated from the hydrozoan jellyfish Aequora victoria. It is known that bioluminescence resonance energy transfer (BRET) is possible between these proteins to generate flashes of green light, but the native function and significance of this phenomenon is unclear. Using the hydrozoan Clytia hemisphaerica, we characterized differential expression of three clytin and four GFP genes in distinct tissues at larva, medusa and polyp stages, corresponding to the major in vivo sites of bioluminescence (medusa tentacles and eggs) and fluorescence (these sites plus medusa manubrium, gonad and larval ectoderms ...

The "Celebrity Apprentice 3" season finale began with the two teams led by Bret Michaels and Holly Robinson Peete trying to complete their tasks. Â In the end, even though Bret Michaels looked a bit overwrought because of an approaching deadline and the camera equipment he needed to shoot his commercials for his ad campaign running late, both teams got their ad campaigns together and presented their products to be reviewed by Snapple. Â But who would Donald Trump hire? Â Who would walk away the winner of "Celebrity Apprentice"?. Bret Michaels, working for the American Diabetes Association, was in attendance in his jeans and everpresent bandana, even though he had some highly publicized medical problems in the past several weeks (most of the "Celebrity Apprentice" was filmed before Bret Michaels experienced his series of hospitalizations).

PreExhastion Study: I think the results that you are finding are logical. In terms of structural engineering, when a single truss members reaches its max stress, the other truss members must pick up the extra load. In the case of a bench press where the triceps and chest form a force couple, if you pre-exhaust the pecs, then the body compensates by working the triceps harder. In the case of the squat, by pre-exhausting the hamstrings, you would expect more activation in the quads to compensate. I think the studies that describe a set to failure also back this up in terms of activation in stages of the various types of muscle fibers.. ...

Calling matches with Jerry Lawler and Vince McMahon over the years:. "I had no idea what the franchise Monday Night Raw was going to eventually mean what it has. I worked with Vince [McMahon] and Jerry Lawler. That was new. Three men in a booth was new for me. Not being the lead guy was new. It was a great, refreshing start. A reboot. At that time, I came from a chaotic WCW with all the changes in management. It was a relief to work for a company where you could get a straight answer from the decision-maker. I loved that part of it.". Working with "Macho Man" Randy Savage and calling 1-2-3 Kid vs. Bret Hart:. "I worked with Randy Savage, which is never easy. I loved his talent. I loved his passion, but he had to trust you. I think he had trust issues, but he was damn sure talented. He and I called the 1-2-3 Kid and Bret Hart. To many in the crowd, Im sure they thought it would be an easy Bret Hart win and that this young guy, Sean Waltman, wouldnt have a chance. It was one of the classic ...

The formation of membrane heterogeneities, e.g., lipid domains and pores, leads to a redistribution of donor (D) and acceptor (A) molecules according to their affinity to the structures formed and the remaining bilayer. If such changes sufficiently influence the Förster resonance energy transfer (FRET) efficiency, these changes can be further analyzed in terms of nanodomain/pore size. This paper is a continuation of previous work on this theme. In particular, it is demonstrated how FRET experiments should be planned and how data should be analyzed in order to achieve the best possible resolution. The limiting resolution of domains and pores are discussed simultaneously, in order to enable direct comparison. It appears that choice of suitable donor/acceptor pairs is the most crucial step in the design of experiments. For instance, it is recommended to use DA pairs, which exhibit an increased affinity to pores (i.e., partition coefficients KD,A | 10) for the determination of pore sizes with radii
Optical sensors and methods are disclosed. The resonance energy transfer between a donor and acceptor pair on a surface is monitored. The change in resonance energy transfer as a function of the change in refractive index of a sensing area disposed between the donor and acceptor pair is utilized to provide various sensing methods and structures.
It doesnt seem like OBrien has done enough to lose the job, but Bielema has spoken highly of Stave since preseason camp. "I think any of the quarterbacks … would admit that Joel has the best arm out of all of them, strength-wise (and) ability to throw the football," Bielema said. "Hes got great composure. "I think the one thing you can count on with Joel is what you called and what you expect to see, the reactions … whether its pre-snap reads (or) whether its reads within the play. "Joels pretty educated. Now, obviously, hes only got one half under his belt … so thats the part thats the unknown." Stave wasnt asked to do much, completing only 2 of 6 passes for 15 yards. He had great field position his first two series, but his first drive, starting at midfield, was sabotaged by a holding call on first down. The next series started at the Utah State 42 and consisted of six straight runs by Montee Ball, resulting in a touchdown. The four series in the fourth quarter were all backed ...
