CAR-dependent and CAR-independent pathways of adenovirus vector-mediated gene transfer and expression in human fibroblasts. (1/7311)

Primary fibroblasts are not efficiently transduced by subgroup C adenovirus (Ad) vectors because they express low levels of the high-affinity Coxsackie virus and adenovirus receptor (CAR). In the present study, we have used primary human dermal fibroblasts as a model to explore strategies by which Ad vectors can be designed to enter cells deficient in CAR. Using an Ad vector expressing the human CAR cDNA (AdCAR) at high multiplicity of infection, primary fibroblasts were converted from being CAR deficient to CAR sufficient. Efficiency of subsequent gene transfer by standard Ad5-based vectors and Ad5-based vectors with alterations in penton and fiber was evaluated. Marked enhancement of binding and transgene expression by standard Ad5 vectors was achieved in CAR-sufficient fibroblasts. Expression by AdDeltaRGDbetagal, an Ad5-based vector lacking the arginine-glycine-aspartate (RGD) alphaV integrin recognition site from its penton base, was achieved in CAR-sufficient, but not CAR-deficient, cells. Fiber-altered Ad5-based vectors, including (a) AdF(pK7)betagal (bearing seven lysines on the end of fiber) (b) AdF(RGD)betagal (bearing a high-affinity RGD sequence on the end of fiber), and (c) AdF9sK betagal (bearing a short fiber and Ad9 knob), demonstrated enhanced gene transfer in CAR-deficient fibroblasts, with no further enhancement in CAR-sufficient fibroblasts. Together, these observations demonstrate that CAR deficiency on Ad targets can be circumvented either by supplying CAR or by modifying the Ad fiber to bind to other cell-surface receptors.  (+info)

Prevention of collagen-induced arthritis by gene delivery of soluble p75 tumour necrosis factor receptor. (2/7311)

Collagen type II-induced arthritis (CIA) in DBA/1 mice can be passively transferred to SCID mice with spleen B- and T-lymphocytes. In the present study, we show that infection ex vivo of splenocytes from arthritic DBA/1 mice with a retroviral vector, containing cDNA for the soluble form of human p75 receptor of tumour necrosis factor (TNF-R) before transfer, prevents the development of arthritis, bone erosion and joint inflammation in the SCID recipients. Assessment of IgG subclass levels and studies of synovial histology suggest that down-regulating the effector functions of T helper-type 1 (Th1) cells may, at least in part, explain the inhibition of arthritis in the SCID recipients. In contrast, the transfer of splenocytes infected with mouse TNF-alpha gene construct resulted in exacerbated arthritis and enhancement of IgG2a antibody levels. Intriguingly, infection of splenocytes from arthritic DBA/1 mice with a construct for mouse IL-10 had no modulating effect on the transfer of arthritis. The data suggest that manipulation of the immune system with cytokines, or cytokine inhibitors using gene transfer protocols can be an effective approach to ameliorate arthritis.  (+info)

Deletion of multiple immediate-early genes from herpes simplex virus reduces cytotoxicity and permits long-term gene expression in neurons. (3/7311)

Herpes simplex virus type 1 (HSV-1) has many attractive features that suggest its utility for gene transfer to neurons. However, viral cytotoxicity and transient transgene expression limit practical applications even in the absence of viral replication. Mutant viruses deleted for the immediate early (IE) gene, ICP4, an essential transcriptional transactivator, are toxic to many cell types in culture in which only the remaining IE genes are expressed. In order to test directly the toxicity of other IE gene products in neurons and develop a mutant background capable of longterm transgene expression, we generated mutants deleted for multiple IE genes in various combinations and tested their relative cytotoxicity in 9L rat gliosarcoma cells, Vero monkey kidney cells, and primary rat cortical and dorsal root neurons in culture. Viral mutants deleted simultaneously for the IE genes encoding ICP4, ICP22 and ICP27 showed substantially reduced cytotoxicity compared with viruses deleted for ICP4 alone or ICP4 in combination with either ICP22, ICP27 or ICP47. Infection of neurons in culture with these triple IE deletion mutants substantially enhanced cell survival and permitted transgene expression for over 21 days. Such mutants may prove useful for efficient gene transfer and extended transgene expression in neurons in vitro and in vivo.  (+info)

Treatment of lysosomal storage disease in MPS VII mice using a recombinant adeno-associated virus. (4/7311)

Mucopolysaccharidosis type VII (MPS VII) is a lysosomal storage disease caused by a genetic deficiency of beta-glucuronidase (GUS). We used a recombinant adeno-associated virus vector (AAV-GUS) to deliver GUS cDNA to MPS VII mice. The route of vector administration had a dramatic effect on the extent and distribution of GUS activity. Intramuscular injection of AAV-GUS resulted in high, localized production of GUS, while intravenous administration produced low GUS activity in several tissues. This latter treatment of MPS VII mice reduced glycosaminoglycan levels in the liver to normal and reduced storage granules dramatically. We show that a single administration of AAV-GUS can provide sustained expression of GUS in a variety of cell types and is sufficient to reverse the disease phenotype at least in the liver.  (+info)

Astrocyte-specific expression of tyrosine hydroxylase after intracerebral gene transfer induces behavioral recovery in experimental parkinsonism. (5/7311)

Parkinson's disease is a neurodegenerative disorder characterized by the depletion of dopamine in the caudate putamen. Dopamine replacement with levodopa, a precursor of the neurotransmitter, is presently the most common treatment for this disease. However, in an effort to obtain better therapeutic results, tissue or cells that synthesize catecholamines have been grafted into experimental animals and human patients. In this paper, we present a novel technique to express tyrosine hydroxylase (TH) in the host's own astrocytes. This procedure uses a transgene in which the expression of a TH cDNA is under the control of a glial fibrillary acidic protein (GFAP) promoter, which confers astrocyte-specific expression and also increases its activity in response to brain injury. The method was tested in a rat model of Parkinson's disease produced by lesioning the striatum with 6-hydroxydopamine. Following microinjection of the transgene into the denervated striatum as a DNA-liposome complex, expression of the transgene was detected by RT-PCR and TH protein was observed specifically in astrocytes by using double-labeling immunofluorescence for GFAP and TH coupled with laser confocal microscopy. Efficacy was demonstrated by significant behavioral recovery, as assessed by a decrease in the pharmacologically induced turning behavior generated by the unilateral denervation of the rat striatum. These results suggest this is a valuable technique to express molecules of therapeutic interest in the brain.  (+info)

High level inhibition of HIV replication with combination RNA decoys expressed from an HIV-Tat inducible vector. (6/7311)

Intracellular immunization, an antiviral gene therapy approach based on the introduction of DNA into cells to stably express molecules for the inhibition of viral gene expression and replication, has been suggested for inhibition of HIV infection. Since the Tat and Rev proteins play a critical role in HIV regulation, RNA decoys and ribozymes of these sequences have potential as therapeutic molecular inhibitors. In the present study, we have generated several anti-HIV molecules; a tat-ribozyme, RRE, RWZ6 and TAR decoys and combinations of decoys, and tested them for inhibition of HIV-1 replication in vitro. We used T cell specific CD2 gene elements and regulatory the HIV inducible promoter to direct high level expression and a 3' UTR sequence for mRNA stabilization. We show that HIV replication was most strongly inhibited with the combination TAR + RRE decoy when compared with the single decoys or the tat-ribozyme. We also show that the Tat-inducible HIV promoter directs a higher level of steady-state transcription of decoys and inhibitors and that higher levels of expression directly relate to increased levels of inhibition of HIV infection. Furthermore, a stabilization of the 3' end of TAR + RRE inhibitor transcripts using a beta-globin 3' UTR sequence leads to an additional 15-fold increase in steady-state RNA levels. This cassette when used to express the best combination decoy inhibitor TAR + RRE, yields high level HIV inhibition for greater than 3 weeks. Taken together, both optimization for high level expression of molecular inhibitors and use of combinations of inhibitors suggest better therapeutic application in limiting the spread of HIV.  (+info)

Thyroid hormone effects on Krox-24 transcription in the post-natal mouse brain are developmentally regulated but are not correlated with mitosis. (7/7311)

Krox-24 (NGFI-A, Egr-1) is an immediate-early gene encoding a zinc finger transcription factor. As Krox-24 is expressed in brain areas showing post-natal neurogenesis during a thyroid hormone (T3)-sensitive period, we followed T3 effects on Krox-24 expression in newborn mice. We analysed whether regulation was associated with changes in mitotic activity in the subventricular zone and the cerebellum. In vivo T3-dependent Krox-24 transcription was studied by polyethylenimine-based gene transfer. T3 increased transcription from the Krox-24 promoter in both areas studied at post-natal day 2, but was without effect at day 6. An intact thyroid hormone response element (TRE) in the Krox-24 promoter was necessary for these inductions. These stage-dependent effects were also seen in endogenous Krox-24 mRNA levels: activation at day 2 and no effect at day 6. Moreover, similar results were obtained by examining beta-galactosidase expression in heterozygous mice in which one allele of the Krox-24 gene was disrupted with an inframe Lac-Z insertion. However, bromodeoxyuridine incorporation showed mitosis to continue through to day 6. We conclude first, that T3 activates Krox-24 transcription during early post-natal mitosis but that this effect is extinguished as development proceeds and second, loss of T3-dependent Krox-24 expression is not correlated with loss of mitotic activity.  (+info)

Reversal of hyperlipidaemia in apolipoprotein C1 transgenic mice by adenovirus-mediated gene delivery of the low-density-lipoprotein receptor, but not by the very-low-density-lipoprotein receptor. (8/7311)

We have shown previously that human apolipoprotein (apo)C1 transgenic mice exhibit hyperlipidaemia, due primarily to an impaired clearance of very-low-density lipoprotein (VLDL) particles from the circulation. In the absence of at least the low-density-lipoprotein receptor (LDLR), it was shown that APOC1 overexpression in transgenic mice inhibited the hepatic uptake of VLDL via the LDLR-related protein. In the present study, we have now examined the effect of apoC1 on the binding of lipoproteins to both the VLDL receptor (VLDLR) and the LDLR. The binding specificity of the VLDLR and LDLR for apoC1-enriched lipoprotein particles was examined in vivo through adenovirus-mediated gene transfer of the VLDLR and the LDLR [giving rise to adenovirus-containing (Ad)-VLDLR and Ad-LDLR respectively] in APOC1 transgenic mice, LDLR-deficient (LDLR-/-) mice and wild-type mice. Remarkably, Ad-VLDLR treatment did not reduce hyperlipidaemia in transgenic mice overexpressing human APOC1, irrespective of both the level of transgenic expression and the presence of the LDLR, whereas Ad-VLDLR treatment did reverse hyperlipidaemia in LDLR-/- and wild-type mice. On the other hand, Ad-LDLR treatment strongly decreased plasma lipid levels in these APOC1 transgenic mice. These results suggest that apoC1 inhibits the clearance of lipoprotein particles via the VLDLR, but not via the LDLR. This hypothesis is corroborated by in vitro binding studies. Chinese hamster ovary (CHO) cells expressing the VLDLR (CHO-VLDLR) or LDLR (CHO-LDLR) bound less APOC1 transgenic VLDL than wild-type VLDL. Intriguingly, however, enrichment with apoE enhanced dose-dependently the binding of wild-type VLDL to CHO-VLDLR cells (up to 5-fold), whereas apoE did not enhance the binding of APOC1 transgenic VLDL to these cells. In contrast, for binding to CHO-LDLR cells, both wild-type and APOC1 transgenic VLDL were stimulated upon enrichment with apoE. From these studies, we conclude that apoC1 specifically inhibits the apoE-mediated binding of triacylglycerol-rich lipoprotein particles to the VLDLR, whereas apoC1-enriched lipoproteins can still bind to the LDLR. The variability in specificity of these lipoprotein receptors for apoC1-containing lipoprotein particles provides further evidence for a regulatory role of apoC1 in the delivery of lipoprotein constituents to different tissues on which these receptors are located.  (+info)

Effective generation of transgenic pigs and mice by linker based sperm-mediated gene transfer. | BMC Biotechnology | Full TextEffective generation of transgenic pigs and mice by linker based sperm-mediated gene transfer. | BMC Biotechnology | Full Text
Transgenic animals have become valuable tools for both research and applied purposes. The current method of gene transfer, microinjection, which is widely used in transgenic mouse production, has only had limited success in producing transgenic animals of larger or higher species. Here, we report a linker based sperm-mediated gene transfer method (LB-SMGT) that greatly improves the production efficiency of large transgenic animals. The linker protein, a monoclonal antibody (mAb C), is reactive to a surface antigen on sperm of all tested species including pig, mouse, chicken, cow, goat, sheep, and human. mAb C is a basic protein that binds to DNA through ionic interaction allowing exogenous DNA to be linked specifically to sperm. After fertilization of the egg, the DNA is shown to be successfully integrated into the genome of viable pig and mouse offspring with germ-line transfer to the F1 generation at a highly efficient rate: 37.5% of pigs and 33% of mice. The integration is demonstrated again by FISH

Development of an safe and efficient in vivo gene delivery method is indispensable for molecular biology research and the progress in the following gene therapy. Over the past few years, hydrodynamic gene delivery with naked DNA has drawn increasing interest in both research and potential clinic applications due to its high efficiency and low risk in triggering immune responses and carcinogenesis in comparison to viral vectors. This method, involving intravenous injection (i.v.) of massive DNA in a short duration, gives a transient but high in vivo gene expression especially in the liver of small animals. In addition to DNA, it has also been shown to deliver other substance such as RNA, proteins, synthetic small compounds and even viruses in vivo. Given its ability to robustly mimic in vivo hepatitis B virus (HBV) production in liver, hydrodynamic gene delivery has become a fundamental and important technology on HBV studies in our group and many other groups.

Neutralizing antibodies (NAbs) against adeno-associated viruses (AAVs) are known to interfere with AAV vector-mediated gene transfer by intravascular delivery. Consequently, gene transfer studies in non-\human being primates may well forecast the effectiveness of gene transfer in humans. Indeed, gene transfer studies using a fresh type of vector have been carried out in rhesus macaques.12,13 The effects from these studies provided the basis for recent hemophilia B gene therapy clinical tests employing an AAV8 vector.13,14,15,16 Gene transfer in mice using AAV vectors results in excellent transduction efficiency.

Gene transfer techniques are an important tool in studies of gene function as well as in the clinical evaluation of new treatments. In research the most important impact of efficient transient and stable gene transfer methods is the generation of new cell lines or animal models for the basic research of protein functions. Many of these methods are based on utilization of viruses as means to target and deliver genes into appropriate cells. Alternatively, recent advances in the RNAi-methodology enable the same delivery method to be used to efficiently silence specific genes in cells.. Successful work with sophisticated viral methods requires special expertise and strict safety considerations both of which are found at all of the biocenters in Finland.. ...

Somatic Gene Therapy | Universitätsklinikum UlmSomatic Gene Therapy | Universitätsklinikum Ulm
We develop new treatment methods for currently incurable disorders. We use and develop techniques for viral and non-viral gene transfer (vectors), which allow to efficiently introduce nucleic acids (DNA, RNA) into body cells. Vector-mediated gene transfer should either help to treat specific diseases (somatic gene therapy) or to prevent them as in the case of infectious diseases (genetic vaccination)..

TY - JOUR. T1 - Cationic lipid-based gene delivery systems. T2 - Pharmaceutical perspectives. AU - Mahato, Ram I.. AU - Rolland, Alain. AU - Tomlinson, Eric. PY - 1997. Y1 - 1997. N2 - Gene delivery systems are designed to control the location of administered therapeutic genes within a patients body. Successful in vivo gene transfer may require (i) the condensation of plasmid and its protection from nuclease degradation, (ii) cellular interaction and internalization of condensed plasmid, (iii) escape of plasmid from endosomes (if endocytosis is involved), and (iv) plasmid entry into cell nuclei. Expression plasmids encoding a therapeutic protein can be, for instance, complexed with cationic liposomes or micelles in order to achieve effective in vivo gene transfer. A thorough knowledge of pharmaceutics and drug delivery, bio-engineering, as well as cell and molecular biology is required to design optimal systems for gene therapy. This mini-review provides a critical discussion on cationic ...

The File Transfer Protocol July 8, 1972 the specified data socket, and it is the servers responsibility to initiate the data connection and data transfer in accordance with the specified data connection parameters. It should be noted that the data socket need not be in the same HOST that initiates the FTP commands via the TELNET connection, but the user or his user-FTP process must ensure a listen on the specified data socket. A practical example of such file transfer to third HOSTs is a maxi-HOST user (who may actually be a TIP user) whishing to transmit a file to or from an I/O device attached to a TIP. It should also be noted that two data connections, one for send and the other for receive, may exist simultaneously. The protocol requires that the TELNET connections be open while data transfer is in progress. It is the responsibility of the user to close the TELNET connections when finished using the FTP service. The server may abort data transfer if the TELNET connections are closed. III. ...

Klinische Studie und experimentelle Untersuchungen zur nicht-viralen Gentherapie solider TumorenKlinische Studie und experimentelle Untersuchungen zur nicht-viralen Gentherapie solider Tumoren
Cancer is one leading causes of death worldwide. Gene therapy belongs to the promising options for treatment of malignant tumors. The non-viral gene therapy is known as safer alternative to the viral gene therapy. For non-viral gene transfer the vector and the transfer technology are of crucial importance. As part of this work a clinical trial was performed to assess efficiency and safety of the non-viral jet-injection. It was shown, that this technology can be used safely in a clinical setting. As a result of this clinical trial we concluded, that vector safety and especially efficiency need further improvements. Based on this optimized non-viral vectors (minicircle, MIDGE) were compared with each other and their respective parental plasmids. The MIDGE vector showed the highest transgene expression due to increased transcription. In preparation of a clinical trial the combined treatment of hTNF-alpha gene transfer and Vindesine chemotherapy was analyzed. Again, the MIDGE vector showed the ...

File Transfer Protocol, FTP - RedorbitFile Transfer Protocol, FTP - Redorbit
Image Caption: Illustrates the FTP connection between a Client and a Server, using the PASV command. Credit: Michael Lorer/Wikipedia (CC BY-SA 3.0). File transfer protocol (FTP) is the protocol of transferring files from one host to another host usually over the Internet. This protocol is normally done by authentication by the user entering a username and password. However, some servers (hosts) allow anonymous connection, which in most cases allows limited access to the site.. The first FTP applications were called command-line applications that were developed before computers used graphical user interfaces (GUIs). The later FTP applications shipped with most operating systems still use the command-line concept but is integrated other applications on the PC.. The original FTP was published on April 16 1971, and replaced in June 1980. The current protocol was released in October 1985. Updates to the current FTP were done in June 1997 with security extensions, and in September 1998 with IPv6 ...

Systemic Delivery of Therapeutic Genes in DMD Models - Muscular DystrophySystemic Delivery of Therapeutic Genes in DMD Models - Muscular Dystrophy
To date efficient widespread expression in skeletal and cardiac muscles has not been demonstrated in large animal models of DMD. Intravascular delivery of AAV vectors demonstrated the proof of concept in mdx mice by restoring functional correction of skeletal muscle, diaphragm and heart disease (Bostick et al. 2009; Gregorevic et al. 2006; Wang et al. 2005). In normal neonate dogs, injection of AAV-9 resulted in expression of a reporter gene, in a dose-dependent manner, in widespread skeletal muscle but not in the heart (Yue et al. 2008). In another study, AAV-6 was the most efficient vector serotype in cardiac gene transfer following percutaneous transendo-cardial delivery to normal adult dogs (Bish et al. 2008). In both studies, no cellular immune responses were observed. More studies are required to determine whether these results could address safety scale-up issues in DMD dogs using a relevant therapeutic transgene, and whether the potential risk of immune responses to the vector and/or ...

There is an ongoing, intensive search for novel therapies to improve the prognosis of patients with the most common and aggressive form of primary brain cancer, glioblastoma multiforme (GBM). Gene transfer is one such approach. Early gene-transfer studies with replication incompetent vectors showed this approach to be generally safe, but ineffective due to limited transduction of the tumor. More recently gene transfer has been attempted with oncolytic, replicating viruses. However these viruses are rapidly cleared by the immune system. To overcome these shortcomings of previous gene transfer protocols, Toca 511 has been developed utilizing a Retroviral Replicating Vector (RRV). This platform has the following potential advantages: 1) The vector only infects dividing cells, 2) The virus stably integrates into the genome of the tumor cells allowing for the potential for long-term control of the tumor, 3) The virus is not intrinsically oncolytic and is not cleared from the tumor by the immune ...

Scientific Protocols - Efficient Viral Gene Transfer to Rat Hearts In VivoScientific Protocols - Efficient Viral Gene Transfer to Rat Hearts In Vivo
Cardiac gene transfer represents a unique strategy to alter the expression of specific genes in the heart that may result in alterations in contractile function. This approach allows us to investigate the role of these pathways on cardiac disease pathogenesis and progression. In rodents, cardiac gene transfer has been achieved predominantly by direct injection into the myocardium or perfusion of an isolated coronary segment. Either approach results in focal overexpression of the transgene and is therefore unlikely to effectively modulate global cardiac function. Here, we provide a gene transfer method that results in global transduction of the heart. We used this technique to demonstrate in vivo that beneficial effects of SUMO1 in the setting of heart failure are dependent on SERCA2a.. ...

Human gene therapy is another medical application that is gaining wide acclaim. In essence, it is the transfer of genetic information into patient tissues and organs. As a result, diseased defective copies of genes can be eliminated or their normal functions rescued. Moreover, the procedure can provide new functions to cells. For Example, to combat cancer and other diseases, the insertion of a gene that causes the production of immune system mediator proteins can be introduced. By this therapy, countless genetic disease could have potential cures further down the road. There are two paths to Gene therapy. The first path is direct transfer of genes into the patient. The second path is the use of living cells as vehicles to transport the genes of interest. These two paths both have certain advantages and disadvantages. Direct gene transfer is the most simplistic way of administering the gene of choice. There are two methods to direct gene transfer. The first method is the process in which genes ...

RNAi technology has another key advantage. Scientists need very small doses of siRNA to carry out their experiments; only a small number of the molecules need to enter a cell to exert their silencing effect. On the other hand, says Hagstrom, the real bottleneck is that you have to get siRNA into cells. Thats not particularly difficult for cells in vitro. But transfecting siRNA into cells in vivo presents a more serious challenge. Mirus, a company that specializes in gene transfer technologies, has developed TransIT-TKO to carry out the task in vitro. Our formulation is a combination of a polymer and an amphipathic polyamine, says Hagstrom. were very far along with the technology for in vitro transfection.

In the second procedure, protoplasts were plated immediately after PEG treatment in a 2ml slab of 0.6% low melting agarose (Paszty and Lurquin, BioTechniques 5:716, 1987) in growth medium with 6% mannitol and 25% CM which was then overlaid with less than 0.5ml liquid growth medium also containing 6% mannitol and 25% CM. After 2 weeks, the slabs were sectioned and placed as above on solid nonselective growth medium for additional proliferation of cells for 7d before selection. Rapid growth of discrete microclusters was observed during this second round of growth on nonselective agar. These microclusters are called colonies since the original aggregates of PEG- treated protoplasts were maintained as unique entities embedded in agarose. This plating method does not allow further division into sib aggregates during growth on nonselective medium. Further, it is also possible that each original cluster of PEG-treated cells may have ...

Because these sensors can be introduced by gene transfer techniques, they may extract neuronal signals from an intact brain more efficiently than conventional organic dyes.

Efficient gene transfer by vectors that can be easily delivered to target organs is desirable in clinical gene therapy. We tested the hypothesis that intracoronary infusion of the nitric oxide donor nitroprusside would increase the efficiency of adenovirus vector-mediated gene transfer to the heart. Intracoronary delivery of an adenovirus encoding murine adenylyl cyclase type VI (Ad.AC(VI)) was performed in adult pigs with and without simultaneous intracoronary infusion of nitroprusside. Animals were killed 12-14 days after Ad.AC(VI) delivery and myocardial adenylyl cyclase activity was measured. Addition of nitroprusside during intracoronary infusion of Ad.AC(VI) was associated with a 4-fold increase in cAMP-generating capacity in the left ventricle. Transgene expression was confirmed by immunoblotting. Intracoronary nitroprusside produced mild dose-dependent changes in blood pressure and heart rate during infusion. Intracoronary nitroprusside infusion is a safe and effective means to increase ...

Approaches to Blocking the Immune Response to Gene Transfer with Viral Vectors | Frontiers Research TopicApproaches to Blocking the Immune Response to Gene Transfer with Viral Vectors | Frontiers Research Topic
Viral vectors are superior tools for gene therapy and as a genetic vaccine platform because viruses have evolved to efficiently infect and transfer their genomes to cells. Several impressive successes in viral vector-based gene therapies have been reported in humans, including restoration of vision in patients with Lebers congenital amaurosis by retinal gene transfer and cures for severe immune deficiencies by gene transfer to hematopoietic stem cells. However, the mammalian immune system has evolved in parallel to fend off invading pathogens such as viruses. Innate and antigen-specific adaptive immune responses against viral vectors and therapeutic transgene products pose serious hurdles for successful gene therapy. Pre-existing immunity in humans, resulting from prior exposure to the parent virus that forms the basis for the gene transfer vehicle may be derived from, often prevents efficient gene transfer. This problem also reduces our ability to use certain vectors for genetic vaccination or in anti

Uptake Pathways and Subsequent Intracellular Trafficking in Nonviral Gene Delivery | Pharmacological ReviewsUptake Pathways and Subsequent Intracellular Trafficking in Nonviral Gene Delivery | Pharmacological Reviews
The successful delivery of therapeutic genes to the designated target cells and their availability at the intracellular site of action are crucial requirements for successful gene therapy. Nonviral gene delivery is currently a subject of increasing attention because of its relative safety and simplicity of use; however, its use is still far from being ideal because of its comparatively low efficiency. Most of the currently available nonviral gene vectors rely on two main components, cationic lipids and cationic polymers, and a variety of functional devices can be added to further optimize the systems. The design of these functional devices depends mainly on our understanding of the mechanisms involved in the cellular uptake and intracellular disposition of the therapeutic genes as well as their carriers. Macromolecules are internalized into cells by a variety of mechanisms, and their intracellular fate is usually linked to the entry mechanism. Therefore, the successful design of a nonviral gene ...

Enhanced transfection efficacy of polyethylenimine by surface modification with arginine, lysine, and leucine - StrathprintsEnhanced transfection efficacy of polyethylenimine by surface modification with arginine, lysine, and leucine - Strathprints
The potential of gene therapy is currently limited by the lack of delivery systems able to efficiently carry therapeutic DNA to their site of action. Non-viral vectors are receiving increasing attention as gene delivery vehicles due to the limitations associated with viral vectors in terms of safety and immunogenicity. Unfortunately, their use is hampered by their lower transfection efficacy compared with viral systems. The present study investigates the possibility of improving transfection by grafting amino acids onto the surface of a non-viral gene delivery system. We chose to use the amino acids arginine, lysine, and leucine because they have been reported to enhance transportation into cells (1-3). As a model delivery system, we chose to use the polymer polyethylenimine (PEI), because it has been widely used for non-viral transfection in vitro and in vivo and combines strong DNA compaction capacity with an intrinsic endosomolytic activity known as the proton sponge effect (4-5). It is ...

Tissue-Specific Gene Delivery via Nanoparticle CoatingTissue-Specific Gene Delivery via Nanoparticle Coating
The use of biomaterials for gene delivery can potentially avoid many of the safety concerns with viral gene delivery. However, the efficacy of polymeric gene delivery methods is low, particularly in vivo. One significant concern is that the interior and exterior composition of polymeric gene delivery nanoparticles are often coupled, with a single polymer backbone governing all functions from biophysical properties of the polymer/DNA particle to DNA condensation and release. In this work we develop electrostatically adsorbed poly(glutamic acid)-based peptide coatings to alter the exterior composition of a core gene delivery particle and thereby affect tissue-specificity of gene delivery function in vivo. We find that with all coating formulations tested, the coatings reduce potential toxicity associated with uncoated cationic gene delivery nanoparticles following systemic injection. Particles coated with a low 2.5:1 peptide:DNA weight ratio (w/w) form large 2 μ sized particles in the presence of ...

Hypertext Transfer Protocol -- HTTP/1.0Hypertext Transfer Protocol -- HTTP/1.0
The Hypertext Transfer Protocol (HTTP) is an application-level protocol with the lightness and speed necessary for distributed, collaborative, hypermedia information systems. HTTP has been in use by the World-Wide Web global information initiative since 1990. This specification reflects common usage of the protocol referred to as HTTP/1.0. This specification describes the features that seem to be consistently implemented in most HTTP/1.0 clients and servers. The specification is split into two sections. Those features of HTTP for which implementations are usually consistent are described in the main body of this document. Those features which have few or inconsistent implementations are listed in Appendix D. Practical information systems require more functionality than simple retrieval, including search, front-end update, and annotation. HTTP allows an open-ended set of methods to be used to indicate the purpose of a request. It builds on the discipline of reference provided by the Uniform ...

Oestradiol enhances tumour regression induced by B7-I/IL-2 adenoviral gene transfer in a murine model of breast cancerOestradiol enhances tumour regression induced by B7-I/IL-2 adenoviral gene transfer in a murine model of breast cancer
The majority of breast cancers are oestrogen dependent and although current treatment strategies have improved, approximately 50% of the patients will develop metastasis. New treatments that result in long-term systemic immunity are therefore being developed. We have previously shown that adenoviral gene transfer of B7-I/IL-2 to murine breast cancer induces a high rate of complete turnout regression and systemic immunity. Since oestrogens not only affect breast cancer but also have been shown to modulate immune function and secretion of immune-regulatory cytokines, we explored whether administration of oestradiol altered the immune response induced by an adenoviral vector expressing B7-I/IL-2. An oestrogen-dependent murine breast cancer tumour was used in ovariectomised mice, supplemented either oestradiol or placebo. We report the somewhat unexpected finding that intratumoral injection of adenovirus expressing B7-I/IL-2 induces complete turnout regression in 76% of oestradiol-supplemented mice, ...

Inherited retinal degenerative diseases are a clinically promising focus of adeno-associated virus (AAV)-mediated gene therapy. These diseases arise from pathogenic mutations in mRNA transcripts expressed in the eyes photoreceptor cells or retinal pigment epithelium (RPE), leading to cell death and structural deterioration. Because current gene delivery methods require an injurious subretinal injection to reach the photoreceptors or RPE and transduce just a fraction of the retina, they are suitable only for the treatment of rare degenerative diseases in which retinal structures remain intact. To address the need for broadly applicable gene delivery approaches, we implemented in vivo-directed evolution to engineer AAV variants that deliver the gene cargo to the outer retina after injection into the eyes easily accessible vitreous humor. This approach has general implications for situations in which dense tissue penetration poses a barrier for gene delivery. A resulting AAV variant mediated ...

Gene therapy is recognized as a medical approach for the treatment of diseases that are difficult to cure, such as tumors. Several viral and non-viral carriers for gene transfer have been developed for either in vivo or ex vivo/in vitro use [1-4]. The most important viral carriers, characterized in laboratory studies and clinical trials, have been inactivated retroviruses, adenoviruses, adeno-associated viruses, and herpes viruses. These viruses show relatively high transfection efficiency, but have some clinical safety problems. On the other hand, non-viral methods of gene delivery, including cationic lipofection, calcium phosphate precipitation, gene guns, and injection of naked DNA, generally show low transfection efficiency but are not pathogenic [1-4]. However, there is another serious issue regarding the present gene delivery methodologies. Almost all the gene delivery methods currently developed have insufficient ability to specifically recognize and target diseased cells and to ...

Molecular basis of Agrobacterium-mediated gene transfer into mammalian cells | ScholarBank@NUSMolecular basis of Agrobacterium-mediated gene transfer into mammalian cells | [email protected]
A novel system for detection of gene transfer between A. tumefaciens and mammalian cells was established. Using this system, Agrobacterium was found to be able to deliver DNA located on its plasmid and chromosome into human cells. Agrobacterium is actively involved in this process; such a kind of DNA transfer might occur widely between bacteria and mammalian cells. The frequency of such a gene transfer was approximately 10-4-10-5 transformants per recipient. Our data showed that this DNA transfer is dependent upon Agrobacterium and independent of its virulence genes. The polymerization of actin played an important role in Agrobacterium internalization and subsequent gene transfer into mammalian cells. In addition, an Agrobacterium sensor protein ChvG was found to be important for the gene transfer into both plant and mammalian cells. The data suggested that ChvG was involved in the regulation of acid-inducible genes and might function as a global sensor protein that can directly or indirectly ...

Since its discovery, evidence that siRNA was able to act as an RNA interference effector, led to its acceptation as a novel medicine. The siRNA approach is very effective, due to its catalytic mechanism, but still the limitations of its cellular delivery should be addressed. One promising form of non-viral gene delivery system is liposomes. The variable and versatile nature of the lipids keeps the possibility to upgrade the liposomal structure, which makes them suitable for encapsulation and delivery of drugs. However, to avoid the limitation of fast release for the hydrophilic drug, we previously designed viscous core liposomes. We aimed in this work to evaluate if these viscous core liposomes (NvcLs) could be of interest for siRNA encapsulation. Then, we sought to add a limited amount of positive charges to provide cell interaction and transfection. Cationic lipid dimyristoylaminopropylaminopropyl or the polymer poly(ethylenimine) were incorporated in NvcL to produce positively charged viscous ...

Glucocorticoid Priming of Nonviral Gene Delivery to hMSCs Increases Tr by Andrew Hamann, Tyler Kozisek et al.Glucocorticoid Priming of Nonviral Gene Delivery to hMSCs Increases Tr by Andrew Hamann, Tyler Kozisek et al.
Human mesenchymal stem cells (hMSCs) are under study for cell and gene therapeutics because of their immunomodulatory and regenerative properties. Safe and efficient gene delivery could increase hMSC clinical potential by enabling expression of transgenes for control over factor production, behavior, and differentiation. Viral delivery is efficient but suffers from safety issues, while nonviral methods are safe but highly inefficient, especially in hMSCs. We previously demonstrated that priming cells with glucocorticoids (Gcs) before delivery of DNA complexes significantly increases hMSC transfection, which correlates with a rescue of transfection-induced metabolic and protein synthesis decline, and apoptosis. In this work, we show that transgene expression enhancement is mediated by transcriptional activation of endogenous hMSC genes by the cytosolic glucocorticoid receptor (cGR) and that transfection enhancement can be potentiated with a GR transcription-activation synergist. We demonstrate that the

This quote is deeply troubling. Genome sequencing did not reveal a new mechanism of evolution. And it is thus also inaccurate to say it would not have been discovered any other way. Lateral gene transfer was studies for many many many years before the first genome sequence was determined. Certainly, comparative genome analysis helped reveal the extent of gene transfer but it is seriously inaccurate to say it revealed a new mechanism of evolution. Here for example is a link to a google search for the specific phrase lateral gene transfer in papers published prior to 1995. And here is one for the phrase horizontal gene transfer ...

Enhancing gene delivery with nanoparticles could ultimately lead to a cure for AlzheimersEnhancing gene delivery with nanoparticles could ultimately lead to a cure for Alzheimers
A number of neurodegenerative disorders, such as Parkinsons or Alzheimer Disease, may potentially be treated by gene therapy, i.e. the delivery of therapeutic genes to neurons. Currently, the most common carrier molecules to deliver the therapeutic gene to the patients target cells are viruses that have been genetically altered to carry normal human DNA. Overall gene delivery efficiency is typically low for nonviral vectors. New research undertaken at The Johns Hopkins University offers a systematic approach to understanding the gene delivery process in neurons and explores the intracellular barriers to nonviral gene delivery and possible ways to improve their effectiveness.

Mucosal IFN-gamma gene transfer inhibits pulmonary allergic responses in mice. | The Journal of ImmunologyMucosal IFN-gamma gene transfer inhibits pulmonary allergic responses in mice. | The Journal of Immunology
Th2 cytokines are associated with the airway inflammation and hyperreactivity in allergic asthma and are potential targets for developing novel therapies. The efficacy of a mucosal cytokine-gene transfer approach was examined in a mouse model for allergic asthma. We showed first that mucosal IFN-gamma gene transfer results in a significant expression of IFN-gamma in the pulmonary epithelium. Significantly, this approach inhibits both Ag- and Th2-cell-induced pulmonary eosinophilia and airway hyperreactivity. These findings suggest that mucosal IFN-gamma gene transfer is effective in modulating pulmonary allergic responses and provides a basis for developing a novel therapeutic approach. ...

Immunotherapy of malignancy by in vivo gene transfer into tumors. | PNASImmunotherapy of malignancy by in vivo gene transfer into tumors. | PNAS
The immune system confers protection against a variety of pathogens and contributes to the surveillance and destruction of neoplastic cells. Several cell types participate in the recognition and lysis of tumors, and appropriate immune stimulation provides therapeutic effects in malignancy. Foreign major histocompatibility complex (MHC) proteins also serve as a potent stimulus to the immune system. In this report, a foreign MHC gene was introduced directly into malignant tumors in vivo in an effort to stimulate tumor rejection. In contrast to previous attempts to induce tumor immunity by cell-mediated gene transfer, the recombinant gene was introduced directly into tumors in vivo. Expression of the murine class I H-2Ks gene within the CT26 mouse colon adenocarcinoma (H-2Kd) or the MCA 106 fibrosarcoma (H-2Kb) induced a cytotoxic T-cell response to H-2Ks and, more importantly, to other antigens present on unmodified tumor cells. This immune response attenuated tumor growth and caused complete ...

Calcium-crosslinked LABL-TAT complexes effectively target gene delivery to ICAM-1 expressing cellsCalcium-crosslinked LABL-TAT complexes effectively target gene delivery to ICAM-1 expressing cells
Targeted gene delivery using non-viral vectors is a highly touted scheme to reduce the potential for toxic or immunological side effects by reducing dose. In previous reports, TAT polyplexes with DNA have shown relatively poor gene delivery. The transfection efficiency has been enhanced by condensing TAT/DNA complexes to a small particle size using calcium. To explore the targetability of these condensed TAT complexes, LABL peptide targeting intercellular cell-adhesion molecule-1 (ICAM-1) was conjugated to TAT peptide using a polyethylene glycol (PEG) spacer. PEGylation reduced the transfection efficiency of TAT, but TAT complexes targeting ICAM-1 expressing cells regained much of the lost transfection efficiency. Targeted block peptides properly formulated with calcium offer promise for gene delivery to ICAM-1 expressing cells at sites of injury or inflammation. ...

Definition of environment in regard to interaction with genotypes can be widen to include sexes and major genes. Interaction of sexes with genotypes has been found in meat-type chickens under extreme environmental conditions. In this case, sexes are regarded as environments. Interaction of sexes with environments has been also reported. It appears that overall efficiency of broiler production can be improved by placing males in more optimal environments, and females in less optimal ones. Interaction of major genes for disease resistance with genotypes, i.e., genetic background was found to affect their level of expression. This type of interaction is essential to the utilization of gene transfer technology; an appropriate method for its analysis is described ...

One realization that has come from comparing multiple bacterial genome sequences, including multiple isolates from the same species, is that gene transfer is an important force in bacterial genome evolution. In the laboratory gene transfer is essential for the study of bacteria and for learning more about all living organisms. Three processes in bacteria can broadly define the transfer of DNA: transformation, transduction, and conjugation. This chapter focuses on the many genetic tools available to manipulate the genetic content of Escherichia coli. A DNA molecule that does not have its own origin of replication must integrate into either the host chromosome or another autonomously replicating element such as an endogenous plasmid. In E. coli a modified derivative of the bacteriophage T4 offers some advantages for transduction in that it packages twice as much DNA as P1 and also is less sensitive to capsules found on many pathogenic strains of E. coli. Transformation of bacteria by use of either

The matrix is preferably in the form of a microparticle such as a microsphere (where the gene is dispersed throughout a solid polymeric matrix) or microcapsule (gene is stored in the core of a polymeric shell), a film, an implant, or a coating on a device such as a stent. The size and composition of the polymeric device is selected to result in favorable release kinetics in tissue. The size is also selected according to the method of delivery which is to be used, typically injection or administration of a suspension by aerosol into the nasal and/or
