A fractionated cell extract that maintains a biological function. A subcellular fraction isolated by ultracentrifugation or other separation techniques must first be isolated so that a process can be studied free from all of the complex side reactions that occur in a cell. The cell-free system is therefore widely used in cell biology. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p166)
The biosynthesis of PEPTIDES and PROTEINS on RIBOSOMES, directed by MESSENGER RNA, via TRANSFER RNA that is charged with standard proteinogenic AMINO ACIDS.
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.
Established cell cultures that have the potential to propagate indefinitely.
The rate dynamics in chemical or physical systems.
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.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION.
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.

Bcl-2 regulates amplification of caspase activation by cytochrome c. (1/7010)

Caspases, a family of specific proteases, have central roles in apoptosis [1]. Caspase activation in response to diverse apoptotic stimuli involves the relocalisation of cytochrome c from mitochondria to the cytoplasm where it stimulates the proteolytic processing of caspase precursors. Cytochrome c release is controlled by members of the Bcl-2 family of apoptosis regulators [2] [3]. The anti-apoptotic members Bcl-2 and Bcl-xL may also control caspase activation independently of cytochrome c relocalisation or may inhibit a positive feedback mechanism [4] [5] [6] [7]. Here, we investigate the role of Bcl-2 family proteins in the regulation of caspase activation using a model cell-free system. We found that Bcl-2 and Bcl-xL set a threshold in the amount of cytochrome c required to activate caspases, even in soluble extracts lacking mitochondria. Addition of dATP (which stimulates the procaspase-processing factor Apaf-1 [8] [9]) overcame inhibition of caspase activation by Bcl-2, but did not prevent the control of cytochrome c release from mitochondria by Bcl-2. Cytochrome c release was accelerated by active caspase-3 and this positive feedback was negatively regulated by Bcl-2. These results provide evidence for a mechanism to amplify caspase activation that is suppressed at several distinct steps by Bcl-2, even after cytochrome c is released from mitochondria.  (+info)

C/EBPalpha regulates generation of C/EBPbeta isoforms through activation of specific proteolytic cleavage. (2/7010)

C/EBPalpha and C/EBPbeta are intronless genes that can produce several N-terminally truncated isoforms through the process of alternative translation initiation at downstream AUG codons. C/EBPbeta has been reported to produce four isoforms: full-length 38-kDa C/EBPbeta, 35-kDa LAP (liver-enriched transcriptional activator protein), 21-kDa LIP (liver-enriched transcriptional inhibitory protein), and a 14-kDa isoform. In this report, we investigated the mechanisms by which C/EBPbeta isoforms are generated in the liver and in cultured cells. Using an in vitro translation system, we found that LIP can be generated by two mechanisms: alternative translation and a novel mechanism-specific proteolytic cleavage of full-length C/EBPbeta. Studies of mice in which the C/EBPalpha gene had been deleted (C/EBPalpha-/-) showed that the regulation of C/EBPbeta proteolysis is dependent on C/EBPalpha. The induction of C/EBPalpha in cultured cells leads to induced cleavage of C/EBPbeta to generate the LIP isoform. We characterized the cleavage activity in mouse liver extracts and found that the proteolytic cleavage activity is specific to prenatal and newborn livers, is sensitive to chymostatin, and is completely abolished in C/EBPalpha-/- animals. The lack of cleavage activity in the livers of C/EBPalpha-/- mice correlates with the decreased levels of LIP in the livers of these animals. Analysis of LIP production during liver regeneration showed that, in this system, the transient induction of LIP is dependent on the third AUG codon and most likely involves translational control. We propose that there are two mechanisms by which C/EBPbeta isoforms might be generated in the liver and in cultured cells: one that is determined by translation and a second that involves C/EBPalpha-dependent, specific proteolytic cleavage of full-length C/EBPbeta. The latter mechanism implicates C/EBPalpha in the regulation of posttranslational generation of the dominant negative C/EBPbeta isoform, LIP.  (+info)

Interaction of inflammatory cells and oral microorganisms. II. Modulation of rabbit polymorphonuclear leukocyte hydrolase release by polysaccharides in response to Streptococcus mutans and Streptococcus sanguis. (3/7010)

The release of lysosomal hydrolases from polymorphonuclear leukocytes (PMNs) has been postulated in the pathogenesis of tissue injury in periodontal disease. In the present study, lysosomal enzyme release was monitored from rabbit peritoneal exudate PMNs exposed to Streptocccus mutans or Streptococcus sanguis. S. mutans grown in brain heart infusion (BHI) broth failed to promote significant PMN enzyme release. S. sanguis grown in BHI broth, although more effective than S. mutants, was a weak stimulus for promotion of PMN hydrolase release. Preincubation of washed, viable S. mutans in sucrose or in different-molecular-weight dextrans resulted in the ability of the organisms to provoke PMN release reactions. This effect could bot be demonstrated with boiled or trypsinized S. mutans or with viable S. sanguis. However, when grown in BHI broth supplemented with sucrose, but not with glucose, both S. mutans and S. sanguis triggered discharge of PMN enzymes. The mechanism(s) whereby dextran or sucrose modulates PMN-bacterial interaction may in some manner be related to promotion of microbial adhesiveness or aggregation by dextran and by bacterial synthesis of glucans from sucrose.  (+info)

Acetyl-CoA:1-O-alkyl-2-lyso-sn-glycero-3-phosphocholine acetyltransferase is directly activated by p38 kinase. (4/7010)

Acetyl-CoA:1-O-alkyl-2-lyso-sn-glycero-3-phosphocholine acetyltransferase, along with phospholipase A2, is a key regulator of platelet-activating factor biosynthesis via the remodeling pathway. We have now obtained evidence in human neutrophils indicating that this enzyme is regulated by a specific member of the mitogen-activated protein kinases, namely the p38 kinase. We earlier demonstrated that tumor necrosis factor-alpha (TNF-alpha) as well as N-formyl-methionyl-leucyl-phenylalanine treatment leads to increased phosphorylation and activation of p38 kinase in human neutrophils. Strikingly, in the present study these stimuli increased the catalytic activity of acetyltransferase up to 3-fold, whereas 4-phorbol 12-myristate 13-acetate, which activates the extracellular-regulated kinases (ERKs) but not p38 kinase, had no effect. Furthermore, a selective inhibitor of p38 kinase, SB 203580, was able to abolish the TNF-alpha- and N-formyl-methionyl-leucyl-phenylalanine-induced activation of acetyltransferase. The same effect was not observed in the presence of an inhibitor that blocked ERK activation (PD 98059). Complementing the findings in intact cells, we have shown that recombinant, activated p38 kinase added to microsomes in the presence of Mg2+ and ATP increased acetyltransferase activity to the same degree as in microsomes obtained from TNF-alpha-stimulated cells. No activation of acetyltransferase occurred upon treatment of microsomes with either recombinant, activated ERK-1 or ERK-2. Finally, the increases in acetyltransferase activity induced by TNF-alpha could be ablated by treating the microsomes with alkaline phosphatase. Thus acetyltransferase appears to be a downstream target for p38 kinase but not ERKs. These data from whole cells as well as cell-free systems fit a model wherein stimulus-induced acetyltransferase activation is mediated by a phosphorylation event catalyzed directly by p38 kinase.  (+info)

Terreic acid, a quinone epoxide inhibitor of Bruton's tyrosine kinase. (5/7010)

Bruton's tyrosine kinase (Btk) plays pivotal roles in mast cell activation as well as in B cell development. Btk mutations lead to severe impairments in proinflammatory cytokine production induced by cross-linking of high-affinity IgE receptor on mast cells. By using an in vitro assay to measure the activity that blocks the interaction between protein kinase C and the pleckstrin homology domain of Btk, terreic acid (TA) was identified and characterized in this study. This quinone epoxide specifically inhibited the enzymatic activity of Btk in mast cells and cell-free assays. TA faithfully recapitulated the phenotypic defects of btk mutant mast cells in high-affinity IgE receptor-stimulated wild-type mast cells without affecting the enzymatic activities and expressions of many other signaling molecules, including those of protein kinase C. Therefore, this study confirmed the important roles of Btk in mast cell functions and showed the usefulness of TA in probing into the functions of Btk in mast cells and other immune cell systems. Another insight obtained from this study is that the screening method used to identify TA is a useful approach to finding more efficacious Btk inhibitors.  (+info)

A multisubunit acetyl coenzyme A carboxylase from soybean. (6/7010)

A multisubunit form of acetyl coenzyme A (CoA) carboxylase (ACCase) from soybean (Glycine max) was characterized. The enzyme catalyzes the formation of malonyl CoA from acetyl CoA, a rate-limiting step in fatty acid biosynthesis. The four known components that constitute plastid ACCase are biotin carboxylase (BC), biotin carboxyl carrier protein (BCCP), and the alpha- and beta-subunits of carboxyltransferase (alpha- and beta-CT). At least three different cDNAs were isolated from germinating soybean seeds that encode BC, two that encode BCCP, and four that encode alpha-CT. Whereas BC, BCCP, and alpha-CT are products of nuclear genes, the DNA that encodes soybean beta-CT is located in chloroplasts. Translation products from cDNAs for BC, BCCP, and alpha-CT were imported into isolated pea (Pisum sativum) chloroplasts and became integrated into ACCase. Edman microsequence analysis of the subunits after import permitted the identification of the amino-terminal sequence of the mature protein after removal of the transit sequences. Antibodies specific for each of the chloroplast ACCase subunits were generated against products from the cDNAs expressed in bacteria. The antibodies permitted components of ACCase to be followed during fractionation of the chloroplast stroma. Even in the presence of 0.5 M KCl, a complex that contained BC plus BCCP emerged from Sephacryl 400 with an apparent molecular mass greater than about 800 kD. A second complex, which contained alpha- and beta-CT, was also recovered from the column, and it had an apparent molecular mass of greater than about 600 kD. By mixing the two complexes together at appropriate ratios, ACCase enzymatic activity was restored. Even higher ACCase activities were recovered by mixing complexes from pea and soybean. The results demonstrate that the active form of ACCase can be reassembled and that it could form a high-molecular-mass complex.  (+info)

Mos positively regulates Xe-Wee1 to lengthen the first mitotic cell cycle of Xenopus. (7/7010)

Several key developmental events occur in the first mitotic cell cycle of Xenopus; consequently this cycle has two gap phases and is approximately 60-75 min in length. In contrast, embryonic cycles 2-12 consist only of S and M phases and are 30 min in length. Xe-Wee1 and Mos are translated and degraded in a developmentally regulated manner. Significantly, both proteins are present in the first cell cycle. We showed previously that the expression of nondegradable Mos, during early interphase, delays the onset of M phase in the early embryonic cell cycles. Here we report that Xe-Wee1 is required for the Mos-mediated M-phase delay. We find that Xe-Wee1 tyrosine autophosphorylation positively regulates Xe-Wee1 and is only detected in the first 30 min of the first cell cycle. The level and duration of Xe-Wee1 tyrosine phosphorylation is elevated significantly when the first cell cycle is elongated with nondegradable Mos. Importantly, we show that the tyrosine phosphorylation of Xe-Wee1 is required for the Mos-mediated M-phase delay. These findings indicate that Mos positively regulates Xe-Wee1 to generate the G2 phase in the first cell cycle and establish a direct link between the MAPK signal transduction pathway and Wee1 in vertebrates.  (+info)

The retinoblastoma protein alters the phosphorylation state of polyomavirus large T antigen in murine cell extracts and inhibits polyomavirus origin DNA replication. (8/7010)

The retinoblastoma tumor suppressor protein (pRb) can associate with the transforming proteins of several DNA tumor viruses, including the large T antigen encoded by polyomavirus (Py T Ag). Although pRb function is critical for regulating progression from G1 to S phase, a role for pRb in S phase has not been demonstrated or excluded. To identify a potential effect of pRb on DNA replication, pRb protein was added to reaction mixtures containing Py T Ag, Py origin-containing DNA (Py ori-DNA), and murine FM3A cell extracts. We found that pRb strongly represses Py ori-DNA replication in vitro. Unexpectedly, however, this inhibition only partially depends on the interaction of pRb with Py T Ag, since a mutant Py T Ag (dl141) lacking the pRb interaction region was also significantly inhibited by pRb. This result suggests that pRb interferes with or alters one or more components of the murine cell replication extract. Furthermore, the ability of Py T Ag to be phosphorylated in such extracts is markedly reduced in the presence of pRb. Since cyclin-dependent kinase (CDK) phosphorylation of Py T Ag is required for its replication function, we hypothesize that pRb interferes with this phosphorylation event. Indeed, the S-phase CDK complex (cyclin A-CDK2), which phosphorylates both pRb and Py T Ag, alleviates inhibition caused by pRb. Moreover, hyperphosphorylated pRb is incapable of inhibiting replication of Py ori-DNA in vitro. We propose a new requirement for maintaining pRb phosphorylation in S phase, namely, to prevent deleterious effects on the cellular replication machinery.  (+info)

In this study, we present a novel technique for the synthesis of complex prokaryotic and eukaryotic proteins by using a continuous-exchange cell-free (CECF) protein synthesis system based on extracts from cultured insect cells. Our approach consists of two basic elements: First, protein synthesis is performed in insect cell lysates which harbor endogenous microsomal vesicles, enabling a translocation of de novo synthesized target proteins into the lumen of the insect vesicles or, in the case of membrane proteins, their embedding into a natural membrane scaffold. Second, cell-free reactions are performed in a two chamber dialysis device for 48 h. The combination of the eukaryotic cell-free translation system based on insect cell extracts and the CECF translation system results in significantly prolonged reaction life times and increased protein yields compared to conventional batch reactions. In this context, we demonstrate the synthesis of various representative model proteins, among them cytosolic

N2 - Cell-free hemoglobin-synthesizing systems from erythrocytes of 4- and 17-day chick embryos have been developed. These systems have been used to investigate possible structural and functional differences in factors involved in protein synthesis obtained from these different developmental stages. Each cell-free system consists of three major cellular fractions i.e., the S-100 supernatant, the salt-washed ribosomes, and the 0.5 m KCl ribosomal wash. When the ribosomal wash fraction from one developmental stage is included in a cell-free system containing ribosomes and S-100 supernatant from the other developmental stage, a drastic reduction in the kinetics of [3H]leucine incorporation into globin products is observed, when compared to the homologous control cell-free systems.

Engineered antibodies are key players in therapy, diagnostics and research. In addition to full size immunoglobulin gamma (IgG) molecules, smaller formats of recombinant antibodies, such as single-chain variable fragments (scFv) and antigen binding fragments (Fab), have emerged as promising alternatives since they possess different advantageous properties. Cell-based production technologies of antibodies and antibody fragments are well-established, allowing researchers to design and manufacture highly specific molecular recognition tools. However, as these technologies are accompanied by the drawbacks of being rather time-consuming and cost-intensive, efficient and powerful cell-free protein synthesis systems have been developed over the last decade as alternatives. So far, prokaryotic cell-free systems have been the focus of interest. Recently, eukaryotic in vitro translation systems have enriched the antibody production pipeline, as these systems are able to mimic the natural pathway of antibody
The primary objective of our work was to find a practical solution to the limitations of GPCR expression imposed by heterologous systems. Although relatively large amounts of membrane proteins can be potentially produced in cellular systems, usually a small proportion becomes associated to the membrane [22]. Particularly, GPCRs are confronted to a complex array of trafficking signals, post-translational modifications, and transport systems before reaching the final destination, the plasma membrane. In addition, differences in the lipid bilayer composition and maximal tolerated membrane protein loads can additionally affect the correct insertion, folding, and yield of recombinant GPCRs.. In order to overcome these difficulties, we developed a cell-free expression system supplemented with planar membranes [15]. Although, the approach excels in expressing soluble membrane protein products, it fails to produce functional GPCRs. We favor the absence of a functional translocon machinery embedded in ...
Multicopper oxidases (MCOs) are broadly distributed in all kingdoms of life and perform a variety of important oxidative reactions. These enzymes have potential biotechnological applications; however, the applications are impeded by low expression yields in traditional recombinant hosts, solubility issues, and poor copper cofactor assembly. As an alternative to traditional recombinant protein expression, we show the ability to use cell-free protein synthesis (CFPS) to produce complex MCO proteins with high soluble titers. Specifically, we report the production of MCOs in an Escherichia coli-based cell-free transcription-translation system. Total yields as high as 1.2 mg mL-1 were observed after a 20-h batch reaction. More than 95% of the protein was soluble and activity was obtained by simple post-CFPS addition of copper ions in the form of CuSO4. Scale-up reactions were achieved from 15 to 100 μL without a decrease in productivity and solubility. CFPS titers were higher than in vivo expression ...
Malaria is a major public health burden and developing the next generation of anti-malarials is vital to control the spread of disease. Protein arrays, which can investigate binding of many proteins to various probes simultaneously, are becoming an important tool in the drug development process. Results from protein arrays can be affected by the sample purity, as high amounts of protein from the translation system can mask positive interactions on the arrays. The results would be improved by separating the malarial protein from the translation system proteins. However, purifying the hundreds of proteins for arrays using traditional affinity fusion tags is extremely time-consuming. To reduce the time required to produce protein samples at the desired purity, enrichment schemes were developed that covalently attach a small molecule to the proteins in the wheat cell-free expression system. After translation, separation matrices with high specificity for the small molecule modification were added to ...

The simulation you build in this lesson will not explicitly simulate the carriers in a power and free system. Carriers are the objects that latch onto the dogs of the power and free chain. Usually there are a fixed number of carriers in a system, and they loop around within it. The items that need to be moved in the system are loaded onto available carriers, which then take them to their desired destination.. Admittedly, not simulating the carriers in a power and free system can be justifiably considered a critical oversimplification. Varying the total number of carriers in a system, and their proper distribution, can have huge impacts on overall throughput. However, since the purpose of this tutorial is just to learn how to use FlexSims power and free features, carriers will be left out. This simulation model will assume that carriers are available to pick up items when they are needed.. In FlexSim, enabling power and free operation for a given conveyor or conveyors essentially causes them to ...

The M species (medium sized) dsRNA (1.1-1.4 x 10(6) daltons) isolated from a toxin-producing yeast killer strain (K+R+) and three related, defective interfering (suppressive) S species dsRNAs of the yeast killer-associated cytoplasmic multicomponent viral-like particle system were analyzed by in vitro translation in a wheat germ cell-free protein synthesis system. Heat-denatured M species dsRNA programmed the synthesis of two major polypeptides, M-P1 (32,000 daltons) and M-P2 (30,000 daltons). M-P1 has been shown by the criteria of proteolytic peptide mapping and cross-antigenicity to contain ihe 12,000 dalton polypeptide corresponding to the in vivo produced killer toxin, thus establishing thiat it is the M species dsRNA which carries the toxin gene. An M species dsRNA obtained from a neutral strain (K-R+) also programmed the in vitro synthesis of a polypeptide identical in molecular weight to M-P1, thus indicating that the cytoplasmic determinant of the mutant neutral phenotype is either a simple
Abstract:. Cell-free expression is a key technology for the production of difficult proteins such as membrane proteins or toxins. Complexity of protein synthesis is reduced to the basic translation process and yields in preparative scales of even critical proteins can routinely be obtained [Haberstock et al Prot Expr Purific 2012]. We use a library of well-defined home-made lysates for our expression reactions, having modified proteome compositions adjusted according to special applications. The open nature of cell-free reactions furthermore allows to design target-specific expression environments by supplying ligands, substrates, chaperones or hydrophobic environments for the efficient folding and solubilization of synthesized proteins [Henrich et al FEBS Lett 2015; Hein et al J Eng Life Sci 2014; Schwarz et al Nat Prot 2007]. While the development of basic cell-free expression protocols can relatively fast established, the optimization of product quality in view of complete folding, disulfide ...

Cell-free protein synthesis is a powerful method to explore the structure and function of membrane proteins and to analyze the targeting and translocation of proteins across the ER membrane. Developing a cell-free system based on cultured cells for the synthesis of membrane proteins could provide a highly reproducible alternative to the use of tissues from living animals. We isolated Sf21 microsomes from cultured insect cells by a simplified isolation procedure and evaluated the performance of the translocation system in combination with a cell-free translation system originating from the same source. The isolated microsomes contained the basic translocation machinery for polytopic membrane proteins including SRP-dependent targeting components, translocation channel (translocon)-dependent translocation, and the apparatus for signal peptide cleavage and N-linked glycosylation. A transporter protein synthesized with the cell-free system could be functionally reconstituted into a lipid bilayer. In addition

Aceptado el 11 de abril de 2005.. ABSTRACT. Every day, new proteins are discovered and the need to understand its function arises. Human proteins have a special interest, because to know its role in the cell may lead to the design of a cure for a disease. In order to obtain such information, we need enough protein with a high degree of purity, and in the case of the human proteins, it is almost impossible to achieve this by working on human tissues. For that reason, the use of expression systems is needed. Bacteria, yeast, animals and plants have been genetically modified to produce proteins from different species. Even cell free systems have been developed for that purpose. Here, we briefly review the options with their advantages and drawback, and the purification systems and analysis that can be done to gain understanding on the function and structure of the protein of interest..

Genomics-based target identification and screening using cell free systems has been the dominating principle in cancer drug discovery during the recent decade [6]. As an alternative to this approach the use of phenotype-cell-based screening may provide some distinct advantages [35]. We here performed a conditional screen with the aim of identifying compounds that are cytotoxic to multidrug resistant myeloma cells. A chemically diverse compound library was used for this purpose. The screening hit RH02104/VLX40 was the only compound that fulfilled the pre-determined criteria of a SI less than 50% in myeloma 8226/Dox40 and more than 50% in parental RPMI 8226 cells. In validation experiments VLX40 was found the difference was, albeit statistically significant, small. It can not be excluded that subtle differences in drug uptake and proliferation characteristics of the cell lines, not related to drug transporters, could contribute to the difference observed.. For exploration of mechanisms of action ...

The cell-free DNA (cfDNA) is always present in plasma, and it is biomarker of growing interest in prenatal diagnostics as well as in oncology and transplantology for therapy efficiency monitoring. But does this cfDNA have a physiological role? Here we show that cfDNA presence and clearance in plasma of healthy individuals plays an indispensable role in immune system regulation. We exposed THP1 cells to healthy individuals plasma with (NP) and without (TP) cfDNA. In cells treated with NP, we found elevated expression of genes whose products maintain immune system homeostasis. Exposure of cells to TP triggered an innate immune response (IIR), documented particularly by elevated expression of pro-inflammatory interleukin 8. The results of mass spectrometry showed a higher abundance of proteins associated with IIR activation due to the regulation of complement cascade in cells cultivated with TP. These expression profiles provide evidence that the presence of cfDNA and its clearance in plasma of healthy
Assay of cell-free DNA in blood offers an approach to assessment of tumor DNA. We sought to determine whether Epstein-Barr virus (EBV) DNA in cell-free blood is also a good surrogate for the presence of tumor DNA in children with Hodgkin lymphoma, as it is in adults, and whether it correlates with pediatric outcomes. Pediatric patients enrolled in a Childrens Oncology Group trial (AHOD0031) were studied at baseline and at 8 days after the initiation of treatment. At baseline, EBV DNA in cell-free blood correlated with the presence of EBV in tumor, and EBV DNA 8 days after the initiation of therapy predicted inferior event-free survival ...

Areas covered: We review the advantages and disadvantages of different cell-free protein arrays, with an emphasis on the methods ...
In vitro biosystems can be easily controlled and accessed without membranes.[16] Notably, in work leading to a Nobel prize the Nirenberg and Matthaei experiment used a cell-free system, of the cell extract-based type, to incorporate chosen amino acids tagged radioactively into synthesized proteins with 30S extracted from E. coli.[12][22] More recent studies, such as the study done by Spirin et al. with prokaryotic and eukaryotic version of their cell-free translation system, have also synthesized proteins with increased production, incorporating techniques like continuous flow to add materials and remove products.[23] With such advances in yield, productivity applications have been expanded, such as the synthesis of fusion proteins to potentially serve as vaccines for B-cell lymphomas.[24] Additionally, cell-free protein synthesis is becoming a new alternative choice for fast protein synthesis.[6]. ...
Nowadays, biotechnological processes play a pivotal role in target protein production. of different classes of proteins. Eukaryotic cell-free systems harboring endogenous microsomal structures for the synthesis of functional membrane proteins and posttranslationally altered proteins are of particular interest BMS-509744 for future applications. Therefore, we present current developments in cell-free protein synthesis based on translationally active CHO cell extracts, underlining the high potential of this platform. We present novel results highlighting the optimization of protein yields, the synthesis of numerous difficult-to-express proteins and the cotranslational incorporation of non-standard amino acids, which was exemplarily exhibited by residue specific labeling of the glycoprotein Erythropoietin and the multimeric TNFRSF9 membrane protein KCSA. Introduction Nowadays, production of recombinant proteins plays a pivotal role in the pharmaceutical industry. In particular, genetically designed ...
Autori: Bogdan Bancia Editorial: 2009.. Rezumat:. The three-dimensional structure determination of proteins represents an important step towards understanding their biological function and thus their roles in living organisms. Using a combination of multidimensional NMR techniques three different biomolecules were analyzed in the present study, E. coli peptidyl - prolyl cis-trans isomerase PpiB, proinsulin connecting peptide and DnaG-C. 15N-HSQC spectra were recorded of PpiB which had been expressed without further purification in a cell-free expression system with amino acid selective isotope labelling. Comparison of spectra before and after ultrafiltration indicated that labelled metabolic by-products are of low molecular weight. Therefore, the labelled protein signals are easily distinguished from those of metabolites. The structure analysis of the proinsulin connecting peptide included the assignment of 1H, 13C and 15N NMR resonances using 2D NMR, measurement of T1 (1H) relaxation times and ...
Cytokinesis, when two daughter cells are physically separated from one another, is the final stage of cell division. How dividing cells signal where the cleavage furrow should be during cytokinesis has long interested cell biologists. A major stumbling block to probing the underlying mechanisms has been the lack of a cell-free and fully controllable experimental system.. In a new paper appearing in Science (10 October 2014, Science 346 (6206):244-247), Phuong Nguyen and Aaron Groen, along with their colleagues at Harvard Medical School (Boston, MA), have reconstituted the organization of cytokinesis signaling outside living cells, using a the cell-free Xenopus system. The authors examined the biophysics involved in spatial signaling during cytokinesis using powerful imaging techniques, taking advantage of microtubule cytokinesis zones that they assembled on the surface of a microscope slide. These cytokinesis zones are relatively large (~20 mm) in the large Xenopus egg (c. 10x larger than ...
TY - JOUR. T1 - Cell-free synthesis of acetylcholine receptor polypeptides. AU - Mendez, Bernadita. AU - Valenzuela, Pablo. AU - Martial, Joseph A.. AU - Baxter, John D.. PY - 1980. Y1 - 1980. N2 - Messenger RNA coding for acetylcholine receptor peptides has been identified. This polyadenylate [poly(A)+]RNA from Torpedo californica directs, in a cell-free system, the synthesis of peptides 60,000, 51,000, 49,000 41,000, and 35,000 daltons which account for approximately 2 percent of the total synthesized proteins. The results suggest that several different messenger RNAs code for the receptor subunits. These proteins react specifically to antiserum to native acteylcholine receptor, suggesting that the primary translational product has conformational features similar to the native receptor. Further, the results support the idea that there is posttranslational modification of receptor subunits as the molecular weights of the cell-free synthesized proteins differ from those of purified receptor ...

The T7 bacteriophage RNA polymerase (T7 RNAP) serves as a model for understanding RNA synthesis, as a tool for protein expression, and as an actuator for synthetic gene circuit design in bacterial cells and cell-free extract. T7 RNAP is an attractive tool for orthogonal protein expression in bacteria owing to its compact single subunit structure and orthogonal promoter specificity. Understanding the mechanisms underlying T7 RNAP regulation is important to the design of engineered T7-based transcription factors, which can be used in gene circuit design. To explore regulatory mechanisms for T7 RNAP-driven expression, we developed a rapid and cost-effective method to characterize engineered T7-based transcription factors using cell-free protein synthesis and an acoustic liquid handler. Using this method, we investigated the effects of the tetracycline operators proximity to the T7 promoter on the regulation of T7 RNAP-driven expression. Our results reveal a mechanism for regulation that functions ...
The 5´terminal m7G cap present on most eukaryotic mRNAs promotes translation in vitro at the initiation level. For most RNAs, elimination of the cap structure causes a loss of stability, especially against exonuclease degradation, and a decrease in the formation of the initiation complex of mRNAs for protein synthesis. Certain prokaryotic mRNAs containing a 5´ terminal cap structure are translated as efficiently as or more efficiently than eukaryotic mRNAs in a eukaryotic cell-free protein synthesizing system. Also a cap requirement has been observed for splicing eukaryotic substrate RNAs. A method for efficient in vitro synthesis of capped RNA using E. coli RNA polymerase primed with m7G(5´ )ppp(5´ )G or m7G(5´ )ppp(5´ )A has been developed by Contreas et al.

Cell-free DNA as a diagnostic marker for cancer: current insights Samanta Salvi,1 Giorgia Gurioli,1 Ugo De Giorgi,2 Vincenza Conteduca,2 Gianluca Tedaldi,1 Daniele Calistri,1 Valentina Casadio1 1Biosciences Laboratory, 2Department of Medical Oncology, Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) IRCCS, Meldola, Italy Abstract: The increasing knowledge of the molecular pathogenesis of cancer and the rapid development of new molecular techniques are promoting the study of early molecular alterations involved in cancer development in body fluids. Specific genetic and epigenetic alterations could be found in plasma, serum, and urine cell-free DNA (cfDNA) and could potentially be used as diagnostic biomarkers for several types of cancers. This review focuses on the role of cfDNA in diagnosis: a PubMed search was performed by selecting papers according to journal impact factor and robustness of statistical analysis. A comprehensive evaluation of

The detection of tumor-derived cell-free DNA in plasma is one of the most promising directions in cancer diagnosis. The major challenge in such approach is how to identify the tiny amount of tumor DNAs out of total cell-free DNAs in blood. Here we propose an ultrasensitive cancer detection method, termed CancerDetector, using the DNA methylation profiles of cell-free DNAs. The key of our method is to probabilistically model the joint methylation patterns of multiple adjacent CpG sites on an individual sequencing read, in order to exploit the pervasive nature of DNA methylation for signal amplification. Therefore, CancerDetector can sensitively identify a trace amount of tumor cfDNAs in plasma, at the level of individual reads. We evaluated CancerDetector on the simulated data, and showed a high concordance of the predicted and true tumor burden. Testing CancerDetector on real plasma data demonstrated its high sensitivity and specificity in detecting tumor DNAs. In addition, the predicted tumor ...

STRO-001 was developed with Sutros proprietary cell-free protein synthesis and site-specific conjugation platforms, which facilitate multiple rounds of antibody and ADC optimization, said Dr. Arturo Molina, a medical oncologist and Sutros chief medical officer.. Sutros Xpress CF+™ platform enables it to produce novel ADCs that directly target cancer cells and avoid a toxic bystander effect on adjacent healthy cells, he added.. Unlike conventional cell-based expression systems, Sutros technology isolates a cells protein production machinery into a cell-free extract, Xtract CF™, which includes all the necessary biochemical components for energy production, transcription and translation. The Xpress CF+™ platform further supports incorporation of non-natural amino acids in specific positions in the protein of interest, allowing for site-specific conjugation of cytotoxins and the creation of homogeneous ADCs. This process is capable of producing single proteins at large scale within ...
A rapid method for gene expression analysis, PURExpress® is a novel cell-free transcription/translation system reconstituted from the purified components necessary for E. coli translation. The relative nuclease-free and protease-free nature of the PURExpress platform preserves the integrity of DNA and RNA templates/ complexes and results in proteins that are free of modification and degradation. Transcription and translation are carried out in a one-step reaction, and require the mixing of only two tubes. With results available in a few hours, PURExpress saves valuable laboratory time and is ideal for high throughput technologies.
The purpose was to investigate total cell-free DNA (cfDNA) in colorectal cancer (CRC) patients during treatment with second-line chemotherapy and in healthy controls and patients with different comorbidities. Patient treated with second-line irinotecan for metastatic CRC (n = 100), a cohort of healthy controls with and without comorbidity (n = 70 and 100, respectively) were included. cfDNA was quantified by an in-house developed quantitative polymerase chain reaction from plasma samples drawn prior to the first cycle of chemotherapy and at time of progression. cfDNA levels were significantly higher in CRC compared to controls, with a clear capability for discriminating between the groups (receiver operation curve analysis; area under the curve 0.82, p , 0.0001). Patients with high levels had a shorter survival from irinotecan compared to those with lover levels. The cohort independent upper normal limit divided patients into high and low risk groups. The progression-free survival (PFS) was 2.1 ...
