AU - Mannan, Ahmad A. AU - Kierzek, Andrzej M. AU - McFadden, Johnjoe. AU - Shimizu, Kazuyuki. PY - 2010/11/19. Y1 - 2010/11/19. N2 - BackgroundIt is quite important to simulate the metabolic changes of a cell in response to the change in culture environment and/or specific gene knockouts particularly for the purpose of application in industry. If this could be done, the cell design can be made without conducting exhaustive experiments, and one can screen out the promising candidates, proceeded by experimental verification of a select few of particular interest. Although several models have so far been proposed, most of them focus on the specific metabolic pathways. It is preferred to model the whole of the main metabolic pathways in Escherichia coli, allowing for the estimation of energy generation and ...

In the first commercial application of this technique, OMT, a private biotechnology company developing a new rat-based human antibody platform, used Sangamos ZFNs to knock out the gene encoding rat immunoglobulin M (IgM), an important gene for rat antibody production. Inactivation of rat IgM expression is the first step in generating rats that exclusively express human antibodies encoded by transgenic human immunoglobulin genes. "Creating a knockout rat was the biggest challenge OMT faced", said Dr. Roland Buelow, CEO of OMT and a senior author of the paper. "Inactivation of endogenous rat antibody expression is essential for human antibody expression in genetically engineered animals. To solve this problem, we used ZFN technology in an application that has the potential to revolutionize genetic engineering of animals ...
Background Ganglioside biosynthesis occurs through a multi-enzymatic pathway which at the lactosylceramide step is branched into several biosynthetic series. Lc3 synthase utilizes a variety of galactose-terminated glycolipids as acceptors by establishing a glycosidic bond in the beta-1,3-linkage to GlcNaAc to extend the lacto- and neolacto-series gangliosides. In order to examine the lacto-series ganglioside functions in mice, we used gene knockout technology to generate Lc3 synthase gene B3gnt5-deficient mice by two different strategies and compared the phenotypes of the two null mouse groups with each other and with their wild-type counterparts. Results B3gnt5 gene knockout mutant mice appeared normal in the embryonic stage and, if they survived delivery, remained normal during early life. However, about 9% developed early-stage growth retardation, 11% died postnatally in less than 2 months, and adults tended to die in 5-15 months, demonstrating splenomegaly and notably enlarged lymph nodes. ...

As to your second point, I would say yes, but. Yes, it does only prove that theyre necessary to fish. But we do produce a whole lot of them - it seems odd that our bodies would waste the amino acids/etc to make a ton of something that has no use whatsoever. Of course, trying the same trick with human embryos is unethical, so its hard to be certain how they might be utilized in us. Mice arent exactly people, and the studies which show a lack of use generally are knockout studies - which means that if they havent actually IDed the right gene, the mice could still be making PrPs that are different. The fact that such a valuable use in a vertebrate model has been identified suggests that we might still have uses for the PrPs.. ...
Background Reverse-engineering gene networks from expression profiles is a difficult problem for which a multitude of techniques have been developed over the last decade. The yearly organized DREAM challenges allow for a fair evaluation and unbiased comparison of these methods. Results We propose an inference algorithm that combines confidence matrices, computed as the standard scores from single-gene knockout data, with the down-ranking of feed-forward edges. Substantial improvements on the predictions can be obtained after the execution of this second step. Conclusions Our algorithm was awarded the best overall performance at the DREAM4 In Silico 100-gene network sub-challenge, proving to be effective in inferring medium-size gene regulatory networks. This success demonstrates once again the decisive importance of gene expression data obtained after systematic gene perturbations and highlights the usefulness of graph analysis to increase the reliability of inference.

books about bacteria gene knockout - posted in Microbiology: Hi! I want to do gene knockout in a G(+) bacteria. I am new in this field, and would like to start with reading. I didnt find any article about gene KO in this bacteria. Would you please recommend some books/ chapters that give systemic introductions about gene knockout in bacteria? Thanks very much!
Animals. The contractile performance was studied in five young (9-14 wk of age) male TR-α1-deficient mice and five wild-type control animals of the same age and weight (28-35 g). The force-frequency relationship (see below) was studied also in muscles from four female TR-α1-deficient mice and four wild-type control mice of the same age and weight. The TR-α1-deficient mice represent a cross between the SV-129/OLa and BALB/c (30). Contractile studies were performed on four male TR-β-deficient (12) and four control mice of the same age and weight as above. This group of mice has a mixed 129/Sv and C57Bl/6J genetic background, and was generated from TR-β+/ − heterozygote backcrosses. The wild-type mice were obtained from crosses of heterozygote TR-α1- or TR-β-deficient mice. The two homozygote wild-type strains were bred in parallel with the respective knockout strains. Thus the knockout strains have the same genetic background as their respective knockout strains: 129/Ola and BALB/c for ...
The graph above shows the effect of 3% DMSO on YBR033W. From the data represented the average doubling rate for the YBR033W knockout strain without DMSO was 634 minutes. When DMSO is added the average doubling time increased to 1292 minutes. This shows that 3% DMSO did add stress to this knockout strain. The average doubling time of WT:BY4735 without DMSO was 514 minutes. The average doubling rate for WT:BY4735 with DMSO was 1529 minutes. If we compare the average doubling rate of WT:BY4735 with DMSO to YBR033W with DMSO we can see that without the YBR033W gene the yeast was able to grow more quickly under DMSO induced stress. ...

A gene knockout (abbreviation: KO) is a genetic technique in which one of an organisms genes is made inoperative ("knocked out" of the organism). However, KO can also refer to the gene that is knocked out or the organism that carries the gene knockout. Knockout organisms or simply knockouts are used to study gene function, usually by investigating the effect of gene loss. Researchers draw inferences from the difference between the knockout organism and normal individuals. The KO technique is essentially the opposite of a gene knock-in. Knocking out two genes simultaneously in an organism is known as a double knockout (DKO). Similarly the terms triple knockout (TKO) and quadruple knockouts (QKO) are used to describe three or four knocked out genes, respectively. However, one needs to distinguish between heterozygous and homozygous KOs. In the former, only one of two gene copies (alleles) is knocked out, in the latter both are knocked out. ...

Nix is a pro-apoptotic gene that is regulated by Histotoxic hypoxia. It expresses a signaling protein related to the BH3-only family. This protein induces autophagy, an intracellular function by which cytoplasmic components are delivered to the lysosome to be broken down and used elsewhere or excreted from the cell.[1] This protein is important in development because it allows cells to have a consistent store of cellular components.[2] It also holds an important role in the differentiation and maturation of erythrocytes and lymphocytes by the process of mitophagy with the help of its regulator BNIP3.[3] Using a gene knockout technique in mice, scientists have been able to attribute this pruning of mitochondria and induction of cellular necrosis to the expression of the Nix gene.[1]. Not only does it hold a role in the differentiation of these immune and oxygen-carrying cells, but it also affects the development and maintenance of heart tissue. It has been found to be a cause of pathologic ...

Previous work on identifying the molecular mechanisms mediating plant-pathogen interactions and reciprocal host responses have little emphasis on developing models that closely resemble host-microbe interaction in planta. This work establishes an amalgamated model of interaction wherein successful pathogens elicit and overcome host defenses activated by microbial signatures and virulence factors. Using a hydroponic co-cultivation model, we assessed the responses of Arabidopsis thaliana Col-0 to Agrobacterium tumefaciens C58 to ameliorate limitations of previous approaches. Comparisons of differential gene expression between directly and indirectly affected host sites by microarray analysis revealed both reactive and pro-active defense responses, respectively. Selected homozygous single-gene knockouts for proactive defenses show variable A. tumefaciens root surface attachment and root secretion profiles. Studying host-microbe responses using hydroponics may improve priming of cash crops against pathogens
CompoZr Zinc Finger Nuclease (ZFN) Technology is a novel system for rapid creation of targeted gene knockouts, genomic insertions or gene editing in eukaryotic systems. ZFNs are highly efficient pairs of custom nucleases designed and made by Sigma-Aldrich to target your gene or genomic sequence of interest. ZFNs (mRNA or plasmid formats) are delivered to cells by transfection methods or to embryos by microinjection. Upon cleavage of the target site, endogenous cellular processes are harnessed to produce targeted mutations that result in gene knockout.
