The molecular basis of multiple vector insertion by gene targeting in mammalian cells. (2/4747)

Gene targeting using sequence insertion vectors generally results in integration of one copy of the targeting vector generating a tandem duplication of the cognate chromosomal region of homology. However, occasionally the target locus is found to contain >1 copy of the integrated vector. The mechanism by which the latter recombinants arise is not known. In the present study, we investigated the molecular basis by which multiple vectors become integrated at the chromosomal immunoglobulin mu locus in a murine hybridoma. To accomplish this, specially designed insertion vectors were constructed that included six diagnostic restriction enzyme markers in the Cmu region of homology to the target chromosomal mu locus. This enabled contributions by the vector-borne and chromosomal Cmu sequences at the recombinant locus to be ascertained. Targeted recombinants were isolated and analyzed to determine the number of vector copies integrated at the chromosomal immunoglobulin mu locus. Targeted recombinants identified as bearing >1 copy of the integrated vector resulted from a Cmu triplication formed by two vector copies in tandem. Examination of the fate of the Cmu region markers suggested that this class of recombinant was generated predominantly, if not exclusively, by two targeted vector integration events, each involving insertion of a single copy of the vector. Both vector insertion events into the chromosomal mu locus were consistent with the double-strand-break repair mechanism of homologous recombination. We interpret our results, taken together, to mean that a proportion of recipient cells is in a predetermined state that is amenable to targeted but not random vector integration.  (+info)

Adventitial delivery minimizes the proinflammatory effects of adenoviral vectors. (3/4747)

PURPOSE: Adenovirus-mediated arterial gene transfer is a promising tool in the study of vascular biology and the development of vascular gene therapy. However, intraluminal delivery of adenoviral vectors causes vascular inflammation and neointimal formation. Whether these complications could be avoided and gene transfer efficiency maintained by means of delivering adenoviral vectors via the adventitia was studied. METHODS: Replication-defective adenoviral vectors encoding a beta-galactosidase (beta-gal) gene (AdRSVnLacZ) or without a recombinant gene (AdNull) were infused into the lumen or the adventitia of rabbit carotid arteries. Two days after infusion of either AdRSVnLacZ (n = 8 adventitial, n = 8 luminal) or AdNull (n = 4 luminal), recombinant gene expression was quantitated by histochemistry (performed on tissue sections) and with a beta-gal activity assay (performed on vessel extracts). Inflammation caused by adenovirus infusion was assessed 14 days after infusion of either AdNull (n = 6) or vehicle (n = 6) into the carotid adventitia. Inflammation was assessed by means of examination of histologic sections for the presence of neointimal formation and infiltrating T cells and for the expression of markers of vascular cell activation (ICAM-1 and VCAM-1). To measure the systemic immune response to adventitial infusion of adenovirus, plasma samples (n = 3) were drawn 14 days after infusion of AdNull and assayed for neutralizing antibodies. RESULTS: Two days after luminal infusion of AdRSVnLacZ, approximately 30% of luminal endothelial cells expressed beta-gal. Similarly, 2 days after infusion of AdRSVnLacZ to the adventitia, approximately 30% of adventitial cells expressed beta-gal. beta-gal expression was present in the carotid adventitia, the internal jugular vein adventitia, and the vagus nerve perineurium. Elevated beta-gal activity (50- to 80-fold more than background; P <.05) was detected in extracts made from all AdRSVnLacZ-transduced arteries. The amount of recombinant protein expression per vessel did not differ significantly between vessels transduced via the adventitia (17.1 mU/mg total protein [range, 8.1 to 71.5]) and those transduced via a luminal approach (10.0 mU/mg total protein [range, 3.9 to 42.6]). Notably, adventitial delivery of AdNull did not cause neointimal formation. In addition, vascular inflammation in arteries transduced via the adventitia (ie, T-cell infiltrates and ICAM-1 expression) was confined to the adventitia, sparing both the intima and media. Antiadenoviral neutralizing antibodies were present in all rabbits after adventitial delivery of AdNull. CONCLUSION: Infusion of adenoviral vectors into the carotid artery adventitia achieves recombinant gene expression at a level equivalent to that achieved by means of intraluminal vector infusion. Because adventitial gene transfer can be performed by means of direct application during open surgical procedures, this technically simple procedure may be more clinically applicable than intraluminal delivery. Moreover, despite the generation of a systemic immune response, adventitial infusion had no detectable pathologic effects on the vascular intima or media. For these reasons, adventitial gene delivery may be a particularly useful experimental and clinical tool.  (+info)

Excess of high activity monoamine oxidase A gene promoter alleles in female patients with panic disorder. (4/4747)

A genetic contribution to the pathogenesis of panic disorder has been demonstrated by clinical genetic studies. Molecular genetic studies have focused on candidate genes suggested by the molecular mechanisms implied in the action of drugs utilized for therapy or in challenge tests. One class of drugs effective in the treatment of panic disorder is represented by monoamine oxidase A inhibitors. Therefore, the monoamine oxidase A gene on chromosome X is a prime candidate gene. In the present study we investigated a novel repeat polymorphism in the promoter of the monoamine oxidase A gene for association with panic disorder in two independent samples (German sample, n = 80; Italian sample, n = 129). Two alleles (3 and 4 repeats) were most common and constituted >97% of the observed alleles. Functional characterization in a luciferase assay demonstrated that the longer alleles (3a, 4 and 5) were more active than allele 3. Among females of both the German and the Italian samples of panic disorder patients (combined, n = 209) the longer alleles (3a, 4 and 5) were significantly more frequent than among females of the corresponding control samples (combined, n = 190, chi2 = 10.27, df = 1, P = 0.001). Together with the observation that inhibition of monoamine oxidase A is clinically effective in the treatment of panic disorder these findings suggest that increased monoamine oxidase A activity is a risk factor for panic disorder in female patients.  (+info)

Mapping the genetic determinants of pathogenicity and plaque phenotype in swine vesicular disease virus. (5/4747)

A series of recombinant viruses were constructed using infectious cDNA clones of the virulent J1'73 (large plaque phenotype) and the avirulent H/3'76 (small plaque phenotype) strains of swine vesicular disease virus to identify the genetic determinants of pathogenicity and plaque phenotype. Both traits could be mapped to the region between nucleotides (nt) 2233 and 3368 corresponding to the C terminus of VP3, the whole of VP1, and the N terminus of 2A. In this region, there are eight nucleotide differences leading to amino acid changes between the J1'73 and the H/3'76 strains. Site-directed mutagenesis of individual nucleotides from the virulent to the avirulent genotype and vice versa indicated that A at nt 2832, encoding glycine at VP1-132, and G at nt 3355, encoding arginine at 2APRO-20, correlated with a large-plaque phenotype and virulence in pigs, irrespective of the origin of the remainder of the genome. Of these two sites, 2APRO-20 appeared to be the dominant determinant for the large-plaque phenotype but further studies are required to elucidate their relative importance for virulence in pigs.  (+info)

Intranasal delivery of recombinant parvovirus-like particles elicits cytotoxic T-cell and neutralizing antibody responses. (6/4747)

We previously demonstrated that chimeric porcine parvovirus-like particles (PPV:VLP) carrying heterologous epitopes, when injected intraperitoneally into mice without adjuvant, activate strong CD4(+) and CD8(+) T-cell responses specific for the foreign epitopes. In the present study, we investigated the immunogenicity of PPV:VLP carrying a CD8(+) T-cell epitope from the lymphocytic choriomeningitis virus (LCMV) administered by mucosal routes. Mice immunized intranasally with recombinant PPV:VLP, in the absence of adjuvant, developed high levels of PPV-specific immunoglobulin G (IgG) and/or IgA in their serum, as well as in mucosal sites such as the bronchoalveolar and intestinal fluids. Antibodies in sera from mice immunized parenterally or intranasally with PPV:VLP were strongly neutralizing in vitro. Intranasal immunization with PPV:VLP carrying the LCMV CD8(+) T-cell epitope also elicited a strong peptide-specific cytotoxic-T-cell (CTL) response. In contrast, mice orally immunized with recombinant PPV:VLP did not develop any antibody or CTL responses. We also showed that mice primed with PPV:VLP are still able to develop strong CTL responses after subsequent immunization with chimeric PPV:VLP carrying a foreign CD8(+) T-cell epitope. These results highlight the attractive potential of PPV:VLP as a safe, nonreplicating antigen carrier to stimulate systemic and mucosal immunity after nasal administration.  (+info)

Detection and induction of equine infectious anemia virus-specific cytotoxic T-lymphocyte responses by use of recombinant retroviral vectors. (7/4747)

Cytotoxic T lymphocytes (CTL) appear to be critical in resolving or reducing the severity of lentivirus infections. Retroviral vectors expressing the Gag/Pr or SU protein of the lentivirus equine infectious anemia virus (EIAV) were constructed and used to evaluate EIAV-specific CTL responses in horses. Three promoters, cytomegalovirus, simian virus SV40, and Moloney murine sarcoma virus (MoMSV) long terminal repeat (LTR), were used, and there was considerable variation in their ability to direct expression of Gag/Pr and SU. Vectors expressing EIAV proteins under the direction of MoMSV LTR and using the gibbon ape leukemia virus (GALV) Env for internalization were efficient at transducing equine kidney (EK) target cells and were effective targets for EIAV-specific CTL lysis. CTL from EIAV-infected horses caused lysis of retroviral vector-transduced EK cells expressing either Gag/Pr or SU in an ELA-A-restricted manner. In contrast, lysis of recombinant vaccinia virus-infected EK cells expressing Gag/Pr and SU/TM was often non-LA-A restricted. Five horses were immunized by direct intramuscular injection with a mixture of retroviral vectors expressing Gag/Pr or SU, and one responded with EIAV-specific CTL. This result indicates that retroviral vector stimulation of CTL in horses needs to be optimized, perhaps by inclusion of appropriate cytokine genes in the constructs. However, the studies demonstrated that retroviral vector-transduced target cells were very effective for in vitro dissection of EIAV-specific CTL responses.  (+info)

Reovirus virion-like particles obtained by recoating infectious subvirion particles with baculovirus-expressed sigma3 protein: an approach for analyzing sigma3 functions during virus entry. (8/4747)

Structure-function studies with mammalian reoviruses have been limited by the lack of a reverse-genetic system for engineering mutations into the viral genome. To circumvent this limitation in a partial way for the major outer-capsid protein sigma3, we obtained in vitro assembly of large numbers of virion-like particles by binding baculovirus-expressed sigma3 protein to infectious subvirion particles (ISVPs) that lack sigma3. A level of sigma3 binding approaching 100% of that in native virions was routinely achieved. The sigma3 coat in these recoated ISVPs (rcISVPs) appeared very similar to that in virions by electron microscopy and three-dimensional image reconstruction. rcISVPs retained full infectivity in murine L cells, allowing their use to study sigma3 functions in virus entry. Upon infection, rcISVPs behaved identically to virions in showing an extended lag phase prior to exponential growth and in being inhibited from entering cells by either the weak base NH4Cl or the cysteine proteinase inhibitor E-64. rcISVPs also mimicked virions in being incapable of in vitro activation to mediate lysis of erythrocytes and transcription of the viral mRNAs. Last, rcISVPs behaved like virions in showing minor loss of infectivity at 52 degrees C. Since rcISVPs contain virion-like levels of sigma3 but contain outer-capsid protein mu1/mu1C mostly cleaved at the delta-phi junction as in ISVPs, the fact that rcISVPs behaved like virions (and not ISVPs) in all of the assays that we performed suggests that sigma3, and not the delta-phi cleavage of mu1/mu1C, determines the observed differences in behavior between virions and ISVPs. To demonstrate the applicability of rcISVPs for genetic studies of protein functions in reovirus entry (an approach that we call recoating genetics), we used chimeric sigma3 proteins to localize the primary determinants of a strain-dependent difference in sigma3 cleavage rate to a carboxy-terminal region of the ISVP-bound protein.  (+info)

Introduction. The use of recombinant DNA technology can only benefit humans Recombinant DNA technology is the combining of the DNA from one organism with DNA from another organism. There are many steps in creating recombinant DNA. It begins with the isolation of a gene of interest. This gene is cut using restriction enzyme which will cut the gene in a particular place. A vector is taken and cut open with the same restriction enzyme as the gene was cut with. A vector is a piece of DNA that is capable of growth. Common vectors are of that of a bacterial plasmid. Once vector and gene have been cut they are joined at their sticky ends by using DNA ligase. The viruses and transgenic bacteria used as vectors in the recombinant DNA technology could undergo mutilation which could produce a new pathogen which we wont be able to control. Recombinant DNA technology can have many benefits to humans; one of these benefits is the process of gene therapy. Gene therapy is a way of treating disease by either ...

Introduction. Andrew Scarborough Definitions of Recombinant DNA technology Recombinant DNA technology, or genetic engineering, is artificially manipulating and modifying nucleic acid molecules to modify an organism or population of organisms, using a wide range of techniques and often involving heredity and reproduction. Some of the genetic engineering techniques involved in humans and animals include artificial insemination, in vitro fertilization (e.g., test-tube babies), sperm banks, cloning, and gene manipulation. The subject of genetic engineering, or recombinant DNA technology, is a difficult subject to take on because of the complex, ethical values surrounding the subject. Genetic engineering has advanced the understanding of many theoretical and practical aspects of gene function and organization. Saying that the use of recombinant DNA can only benefit humans may be correct in some ways, however there are many known negative sides to the argument of whether it should be carried out or ...

The vector DNA (plasmid) containing the new genes must now be inserted into host cells. The cells are made porous to DNA by a number of techniques and become transformed as they take up the recombinant DNA molecule. A group of genetically identical cells, all containing the same recombinant DNA molecule are called clones. The unique gene recombination now may be replicated and expressed by these cells. The students will simulate recombinant DNA techniques and make a polyvalent vaccine paper model. The term polyvalent refers to the ability of a single virus to impart immunity to another, unrelated virus. Immunity is developed against foreign antigens which are molecules that are not recognized as self. For viruses, antigens are often the protein coat. If the gene for the major antigen of one virus is spliced or cloned into a second nonvirulent virus and that antigen is expressed (the protein is made) then this recombinant virus will immunize a host against both. To date several antigens have ...

Step 3 Link the DNA fragment to be cloned to the cloning vector to yield a recombinant DNA. Recombinant DNA, the general name for taking a piece of one strand of DNA and combining it with another strand is sometimes referred to as a chimera. By combining two or more different strands of DNA by using the enzyme DNA ligase scientists are able to create a new strand of DNA. The most common recombinant process involves combining DNA of two different organisms. The ability to produce recombinant DNA molecules has not only revolutionized the study of genetics, but has laid the foundation for much of the biotechnology industry.

Recombinant DNA is used in vaccines that involve the direct injection of genetic material into the human body. This genetic material is in the form of a plasmid, or loop of DNA, from the foreign antigen that is the target of the vaccination. After it is injected through our muscle tissue, our cells take in the DNA and begin to produce the foreign proteins encoded in the plasmids. These proteins promote our bodies´ immune responses to the targeted antigen. DNA vaccinations could become less costly to produce, are potentially safer and are theoretically longer lasting than alternative forms of vaccinations. ...
Not all cells take up the recombinant DNA. Geneticists want only cells that have been transformed with the recombinant DNA. In order to do this they select cells that have taken up the DNA by killing cells that have not.

When the bacteria grow, they produce human insulin, and since they can reproduce about once every 20 minutes, it does not take too long before there are millions and millions of bacteria producing insulin!

We have previously described the purification of a heparin binding growth factor from adult bovine brain named heparin affin regulatory peptide (HARP), which was identical to an uterus derived growth factor named pleiotrophin and to a developmentally regulated neurite promoting factor named heparin-binding growth associated molecule. However, for yet unclear reasons, the mitogenic activity of this purified polypeptide following isolation from animal tissue extracts is a subject of controversy, due to conflicting and irreproducible data when produced by recombinant DNA technologies in E. coli or insect cells. The purified protein was inactive in mitogenic assays but the natural molecule was active in assay of neurite outgrowth. In order to clarify these conflicting results and to obtain a recombinant protein free from other contaminating heparin-binding growth factors, we have cloned human cDNA encoding human HARP, engineered its expression in NIH 3T3 cells and characterised the resulting ...

This is the second of six programs in the FJCs Science in the Courtroom series. Professor Edward S. Mocarski, Jr., of Stanford University Medical School, builds upon his lecture in Part One of the series (Core Concepts of Microbiology) by explaining the basic recombinant DNA and gene-cloning methods used in the field of biotechnology. Mocarski explains how the universality of the genetic code makes it possible for scientists to recombine DNA, that is, take DNA from one organism and move it into another. He also explains how recombinant DNA concepts are used in the expression of human proteins into bacteria, a process in which a human coding sequence is taken and inserted into a bacterial context, allowing the bacteria to produce abundant supplies of a foreign protein (foreign to the bacteria) that can be of commercial and therapeutic use.. ...

Experiments using phage lambda provided early insights into important molecular mechanisms, including genetic recombination and the control of gene expression. Before recombinant DNA technology, the use of lambda, most particularly lambda transducing phages, illustrated the importance of cloning bacterial genes, already providing some insight into how to use cloned genes to advantage. Subsequently, lambda made significant contributions to recombinant DNA technology, including the early generation of genomic and cDNA libraries. More recently, lambda genes associated with recombination have enabled techniques referred to as recombineering to be developed. These techniques permit the refined manipulation, including mutation, of foreign genes in Escherichia coli and their subsequent return to the donor organism. ...
During the last few decades, techniques for manipulating eukaryotic as well as prokaryotic DNA have witnessed a remarkable development. There are three main phases of the development of these techniques, which include recombinant DNA technology and gene cloning; polymerase chain reaction and DNA chips and microarrays. Using recombinant DNA technology, we can isolate and clone single copy of a gene or a DNA segment into an indefinite number of copies, all identical. This became possible, because bacteria, phages and plasmids reproduce in their usual style, even after insertion of foreign DNA, so that the inserted DNA also replicates faithfully with the parent DNA. This technique is called gene cloning. It involves the production of a large number of identical DNA molecules from a single ancestral DNA molecule. The essential characteristic of gene cloning is that the desired gene or DNA fragments must be selectively amplified resulting in a large increase in copy number of selected DNA sequences. ...

Recombinant DNA technology, joining together of DNA molecules from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry. Since the focus of all genetics is the gene, the fundamental goal of laboratory geneticists is to isolate, characterize, and manipulate genes. Although it is relatively easy to isolate a sample of DNA from a collection of cells, finding a specific gene within this DNA sample can be compared to finding a needle in a haystack. Consider the fact that each human cell contains approximately 2 metres (6 feet) of DNA. Therefore, a small tissue sample will contain many kilometres of DNA. However, recombinant DNA technology has made it possible to isolate one gene or any other segment of DNA, enabling researchers to determine its nucleotide sequence, study its transcripts, mutate it in highly specific ways, and reinsert the modified sequence into a living organism. ...

A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known as recombinant DNA technology, use DNA molecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes. Transgenic organisms, a subset of GMOs, are organisms which have inserted DNA that originated in a different species.. ...

For the third year of the program (Vienna, 2011), 16 parents initially expressed an interest in the child care services, but at the actual meeting, only four children under the age of 2 years were registered. The conference site had a beautiful garden/park where the children could play. The resulting recombinant DNA technology became one of the most active branches of molecular biology because it allows the manipulation of the genetic sequences that determine the basic characters of organisms. Ladders are sometimes called also called molecular weight size markers. Normally, a small sample of the genetic material is loaded into a well, a small indentation built into the top of the gel. Generally, it is used for DNA. Molecular biology, the study of the biochemical and molecular processes within cells, especially the processes of DNA replication, RNA transcription, and protein translation, has been widely adopted in toxicology.

Background: The concept of transferring genes to tissues for clinical applications has been discussed for nearly half a century. The exponential increase in our ability to manipulate the genetic material of a cell via recombinant DNA technology has brought this goal closer to realization. The original perception that gene therapy should be considered only for a few major organs as a means of treating life-threatening disorders that are refractory to conventional treatment has changed. There are many non-life-threatening conditions that adversely affect a patients quality of life, for which there are no effective treatments. The lack of suitable treatment has permitted morbidity to become a rational basis for extending the scope of gene therapy. In the past few years, remarkable progress has been made in the field of gene therapy. While considerable problems remain, thus impeding the routine clinical use of gene transfer, gene therapy will have a pervasive and significant impact on areas that ...
Vaccines were first introduced more than 200 years ago and have since played a key role in the reduction of morbidity and mortality caused by infectious diseases. Many of the safest and most effective vaccines in use today are based on attenuated live viruses, as they mimic a live infection without causing disease. However, it is not always practical to take this approach, such as when it may not be safe to do so (e.g., for viruses that cause chronic infections such as HIV) or may not be feasible to manufacture (e.g., for viruses that do not grow well in cell culture such as HCV). In addition, it may preferable in some cases to target immune responses toward specific antigens from the pathogen, rather than the entirety of the genome. In these cases, subunit vaccines consisting of antigens purified from the pathogen or produced by recombinant DNA technology are being developed. However, highly purified proteins are typically not inherently immunogenic, as they usually lack the means to directly
One of the goals of modern biology is to analyze the molecular structure and gain a fuller understanding of how cells, tissues, organs, and entire organisms function, both in a normal state and under pathologic conditions. Significant progress has been made in molecular studies of metabolism pathways, gene expression, cellular signaling, and organ development in human beings. The advent of recombinant DNA technology, polymerase chain reaction (PCR) techniques, and completion of the Human Genome Project are positively affecting human society by not only broadening our knowledge and understanding of disease development but also by bringing about necessary changes in disease treatment. ...
