From population genetics theory, elevating the mutation rate of a large population should progressively reduce average fitness. If the fitness decline is large enough, the population will go extinct in a process known as lethal mutagenesis. Lethal mutagenesis has been endorsed in the virology literature as a promising approach to viral treatment, and several in vitro studies have forced viral extinction with high doses of mutagenic drugs. Yet only one empirical study has tested the genetic models underlying lethal mutagenesis, and the theory failed on even a qualitative level. Here we provide a new level of analysis of lethal mutagenesis by developing and evaluating models specifically tailored to empirical systems that may be used to test the theory. We first quantify a bias in the estimation of a critical parameter and consider whether that bias underlies the previously observed lack of concordance between theory and experiment. We then consider a seemingly ideal protocol that avoids this ...

Undergraduates are often familiar with textbook examples of human mutations that affect coding regions and the subsequent disorders, but they may struggle with understanding the implications of mutations in the regulatory regions of genes. We have designed a laboratory sequence that will allow students to explore the effect random mutagenesis can have on protein function, expression, and ultimately phenotype. Students design and perform a safe and time-efficient random mutagenesis experiment using error-prone rolling circular amplification of a plasmid expressing the inducible fusion protein glutathione S-transferase (GST)-mCherry. Mutagenized and wild-type control plasmid DNA, respectively, are then purified and transformed into bacteria to assess phenotypic changes. While bacteria transformed with the wild type control should be pink, some bacterial colonies transformed with mutagenized plasmids will exhibit a different color. Students attempt to identify their mutations by isolating plasmid from
Site-directed mutagenesis of a sequence to make specific, targeted changes to double stranded DNA. Based on optimised protocols, BaseGene is able to create mutations in virtually every DNA fragment. This is a valuable tool for studying DNA or protein structure and function. Site-directed or random mutagenesis can be applied to any DNA-fragment cloned into a plasmid vector. We can help you to introduce a range of mutations, varying from point mutations to deletions or insertions.. ...
If you have plan to use commercial kits, another choice for short way for your research is use of mutagenesis service company. I realized the mutagenesis cost using commercial kit is never cheap! My estimate is $200 ~ 250 per one mutagenesis reaction using kit (one kit rexn., $20 + purified two primers, $150 + three clone sequencing, $30 + subcloning reagent, $30 : SM, media, agar plate, buffer, tube, tips --- and time). Besides, purchasing kit for just one or two mutant generation is money wasting because remaining kit reagents are useless. Recent biotech companies provide rapid and precise mutagenesis service in affordable prices. Some people in our lab use Mutagenex Inc. (USA) and I found other companies offering in low price ...
Mutations occur when a DNA strand is damaged and the cells own repair mechanism mends the damage so that the end result is different from what it looked like to start with. The mutations thus arise through the organisms own system; regardless of whether it is a spontaneous mutation, a mutation with traditional methods, to which the EU court refers to having shown a history of safe use, or new improved methods of refinement. Since spontaneous mutations as well as mutagenesis through traditional methods have demonstrated safe use, it cannot be interpreted otherwise than that all mutagenesis involving a breach in the DNA strand and mutation induced through the organisms repair system do not cause any safety problems. It is not possible to distinguish in a crop the technique used for mutagenesis, and thus the exception in the GMO Directive must apply regardless of the mutagenesis technique used. In the judgment, it has been decided primarily to review recital 17 in combination with Annex IB of ...

Yesterday Cindy presented the results of her Masters rotation project, which she carried out in our lab over the past couple of months. During the rotation, she worked with Lennart to develop and optimize a new gene excision protocol. Not all details can be revealed yet, but it looks like we can cut long sequences surprisingly early and efficiently!. As was also recognized in Cindys exam presentation, she completed a considerable amount of work. She also became a lively part of the lab - so that time passed too fast, again, and her next rotation period is coming up. We wish the best of luck and exciting results!. ...

In an era when everyone in pop, electronic, hip hop and rock seem to be drinking from the same stream, as Flemons put it, going backwards is one way to cast off the burden of influence. Not that anyone is completely free. But Flemons influence is the songster Papa Charlie Jackson - who youve probably never heard of - as opposed to the iconic bluesman Robert Johnson, so he can adapt the material to his own needs without anyone being the wiser.. Flemons musical interests are voracious. Before helping to cement the legacy of Piedmont black string-band music, he made a scholarly discipline of learning about jug-band music, blues, jazz, old country and early rock and roll. And his choice of homely acoustic instruments - banjo, guitar, harmonica, bones and fife - disguises the fact that hes a killer musician. Although he considers himself a traditionalist, in the sense that he recognizes that theres a right way and a wrong way to play music, hes gotten free in a way that few of his ...

TY - JOUR. T1 - Unraveling innate immunity using large scale N-ethyl-N-nitrosourea mutagenesis. AU - Hoebe, Kasper. AU - Beutler, B.. PY - 2005/5. Y1 - 2005/5. N2 - With the mouse genome almost entirely sequenced and readily accessible to all who wish to examine it, the challenge across most biological disciplines now lies in the decipherment of gene and protein function rather than in the realm of gene identification per se. In the field of innate immunity, forward genetic methods have repeatedly been applied to identify key sensors, adapters, and effector molecules. However, most spontaneous mutations that affect innate immune function have been mapped and cloned, and the need for new monogenic phenotypes has been felt evermore keenly. N-Ethyl-N-nitrosourea (ENU) mutagenesis is an efficient tool for the creation of aberrant monogenic innate immune response phenotypes. In this review, we will discuss the potential of the forward genetic approach and ENU mutagenesis to identify new genes and new ...
As the human genome project approaches completion, the challenge for mammalian geneticists is to develop approaches for the systematic determination of mammalian gene function. Mouse mutagenesis will be a key element of studies of gene function. Phenotype-driven approaches using the chemical mutagen ethylnitrosourea (ENU) represent a potentially efficient route for the generation of large numbers of mutant mice that can be screened for novel phenotypes. The advantage of this approach is that, in assessing gene function, no a priori assumptions are made about the genes involved in any pathway. Phenotype-driven mutagenesis is thus an effective method for the identification of novel genes and pathways. We have undertaken a genome-wide, phenotype-driven screen for dominant mutations in the mouse. We generated and screened over 26,000 mice, and recovered some 500 new mouse mutants. Our work, along with the programme reported in the accompanying paper, has led to a substantial increase in the mouse mutant

Rational design of the recombinant T1 lipase gene by saturation mutagenesis on the oxyanion Gln114 was successfully carried out to afford a library of twenty lipase variants. The objective of the study was to investigate the impact of a single point saturation mutagenesis at the oxyanion Gln114 on the enzymatic behavior and enantioselectivity of T1 lipase. Furthermore, the effect of such mutation in the active site of T1 lipase has never been studied. The selection of the mutation site was based on the close proximity of Gln114 residue to the catalytic machinery and is intimately involved in the substrate-enzyme interaction. It was hypothesized that the mutation could invoke substantial changes in the catalytic efficiency and enantioselectivity of T1 lipase. Computational assessment using YASARA, FoldX and Voronoia 1.0, found significant variations in potential energy, total cavity and protein compactness. It was anticipated that Q114L and Q114M are more stable than T1 lipase. Profiling of the ...
Increased mutation rates under stress allow bacterial populations to adapt rapidly to stressors, including antibiotics. Here we evaluate existing models for the evolution of stress-induced mutagenesis and present a new model arguing that it evolves as a result of a complex interplay between direct selection for increased stress tolerance, second-order selection for increased evolvability and genetic drift. Further progress in our understanding of the evolutionary biology of stress and mutagenesis will require a more detailed understanding both of the patterns of stress encountered by bacteria in nature and of the mutations that are produced under stress. © 2013 Macmillan Publishers Limited.

Drug resistance is an almost inevitable consequence of cancer therapy and ultimately proves fatal for the majority of patients. In many cases this is the consequence of specific gene mutations that have the potential to be targeted and re-sensitize the tumor. The means therefore to saturate the genome with point mutations and that avoids chromosome or nucleotide sequence context bias would open the door to identify all possible drug resistance mutations in cancer models. Here we describe such a method for elucidating drug resistance mechanisms using genome-wide chemical mutagenesis allied to next-generation sequencing. We show that chemically mutagenizing the genome of cancer cells dramatically increases the number of drug-resistant clones and allows the detection of both known and novel drug resistance mutations. We have developed an efficient computational process that allows for the rapid identification of involved pathways and druggable targets. Such a priori knowledge would greatly empower ...
GENETAILOR SITE DIRECTED MUTAGENESIS PDF - Site-specific mutagenesis techniques, also known as site-directed mutagenesis .. GeneTailor Site-Directed mutagenesis system (Invitrogen. I have designed
The concept of lethal mutagenesis has been developed as a means of curing viral infections and has also been used to explain the action of some antiviral drugs. Although mutation is the basis for adaptation and survival, especially in the presence of antiviral drugs, most mutations are detrimental and the theory of lethal mutagenesis holds that an infecting population can be pushed to extinction by an overwhelmingly high mutation rate. Chemical mutagens have been used to increase error rates in a number of RNA viruses including HIV-1 and HCV and have been found to significantly reduce viral titres and, in some cases, achieve extinction. For example, the antiviral activity of the ribonucleoside analogue 5-azacytidine (5-AZC) against HIV-1 has been attributed primarily to an increase in mutant frequency consistent with lethal mutagenesis caused by incorporation of 5-AZC into viral DNA.. A team of researchers from the University of Texas at Austin have now raised serious concerns about the ...
Site-specific mutagenesis techniques are aimed at the precise substitution, insertion or deletion of any coding sequence in vitro. More recently, however, such precise alterations are also being developed for in vivo gene/genome modifications. These techniques are revolutionizing our understanding of the genetic and molecular mechanisms in several biological systems, which could lead to the development of new enzymes, therapeutics as well as improved agricultural applications. ...

Large-scale sequencing of human cancer genomes and mouse transposon-induced tumors has identified a vast number of genes mutated in different cancers. One of the outstanding challenges in this field is to determine which genes, when mutated, contribute to cellular transformation and tumor progression. To identify new and conserved genes that drive tumorigenesis we have developed a novel cancer model in a distantly related vertebrate species, the zebrafish, Danio rerio. The Sleeping Beauty (SB) T2/Onc transposon system was adapted for somatic mutagenesis in zebrafish. The carp ß-actin promoter was cloned into T2/Onc to create T2/OncZ. Two transgenic zebrafish lines that contain large concatemers of T2/ OncZ were isolated by injection of linear DNA into the zebrafish embryo. The T2/OncZ transposons were mobilized throughout the zebrafish genome from the transgene array by injecting SB11 transposase RNA at the 1-cell stage. Alternatively, the T2/OncZ zebrafish were crossed to a transgenic line that

Prior to the implementation of more sophisticated genetic techniques, mutagenesis was often performed using simple chemical mutagens including N-methyl-N-nitro-N-nitroso-guanidine (MMNG) and ethyl methane sulfonate (EMS) . The basic approach involves exposing a population of cells to a controlled dose of mutagen, to generate progeny that carry random genetic mutations The application of this technique has traditionally been limited by two important considerations First, it often proves difficult to strike a balance between efficiency and selectivity; exposure to the mutagen must be carefully controlled in order to maximize the frequency of single mutations Second, it should be noted that chemical mutagenesis is random; the experimenter needs to select or identify mutants of interest from a large pool of random mutants. For more detailed information on the background and procedures involved in chemical mutagenesis, we refer the reader to Miller (1992) The basic protocols that have been described ...

N2 - Background: DNA repair is essential to counteract damage to DNA induced by endo- and exogenous factors, to maintain genome stability. However, challenges to the faithful discrimination between damaged and non-damaged DNA strands do exist, such as mismatched pairs between two regular bases resulting from spontaneous deamination of 5-methylcytosine or DNA polymerase errors during replication. To counteract these mutagenic threats to genome stability, cells evolved the mismatch-specific DNA glycosylases ...
Deletion of the I265-F268 and T271-K277 regions in the large lumenally exposed loop of the CP47 protein are known to lead to a loss of photoautotrophic growth. Here, these regions have been investigated by combinatorial mutagenesis and pseudorevertant mapping. No single amino-acid residue in the I265-F268 region was found to be critical for function, but a large hydrophobic residue at position 267 and preferentially an aromatic residue at position 268 appeared to be required for photoautotrophic growth. Starting from an obligate photoheterotrophic mutant lacking the T271-K277 region, photoautotrophic pseudorevertants were generated with short in-frame tandem repeats near the site of the original deletion, partially or fully restoring the length of the original protein. These pseudorevertants were sensitive to oxygen indicating that the T271-K277 region may provide PS II stability and/or protection against oxygen-dependent photoinactivation. Pseudorevertants with much improved photoautotrophic ...
Axons damaged by acute injury, toxic insults, or neurodegenerative diseases execute a poorly defined autodestruction signaling pathway leading to widespread fragmentation and functional loss. Here, we describe an approach to study Wallerian degeneration in the Drosophila L1 wing vein that allows for analysis of axon degenerative phenotypes with single-axon resolution in vivo. This method allows for the axotomy of specific subsets of axons followed by examination of progressive axonal degeneration and debris clearance alongside uninjured control axons. We developed new Flippase (FLP) reagents using proneural gene promoters to drive FLP expression very early in neural lineages. These tools allow for the production of mosaic clone populations with high efficiency in sensory neurons in the wing. We describe a collection of lines optimized for forward genetic mosaic screens using MARCM (mosaic analysis with a repressible cell marker; i.e., GFP-labeled, homozygous mutant) on all major autosomal arms (

Type 2 diabetes mellitus (T2DM) is the leading disorder of metabolism worldwide, and it is predicted to affect more than 330 million people over the next quarter century, generating increasing social and economic burdens. At the pathophysiological level, T2DM arises from a combination of resistance to the hormone insulin and insufficient production of insulin by the endocrine pancreas. T2DM is a polygenic disorder, and many of the genes involved are still unknown. N-ethyl-N-nitrosourea (ENU)-mutagenesis is a forward genetic approach that can be used to identify genes that can be mutated to cause a phenotype of interest. In an effort to identify genes that play a role in regulating blood glucose levels we performed an ENU screen in mice. Recessive and dominant screens were performed, and we identified fourteen lines of mice with evidence for heritable hyperglycemia. Glucokinase (Gck) was a candidate gene, and so we sequenced for Gck mutations in most of the fourteen lines. We identified two lines ...
Full realization of the value of the loxP-flanked alleles generated by the International Knockout Mouse Consortium will require a large set of well-characterized cre-driver lines. However, many cre driver lines display excision activity beyond the intended tissue or cell type, and these data are frequently unavailable to the potential user. Here we describe a high-throughput pipeline to extend characterization of cre driver lines to document excision activity in a wide range of tissues at multiple time points and disseminate these data to the scientific community. Our results show that the majority of cre strains exhibit some degree of unreported recombinase activity. In addition, we observe frequent mosaicism, inconsistent activity and parent-of-origin effects. Together, these results highlight the importance of deep characterization of cre strains, and provide the scientific community with a critical resource for cre strain information.

A) DNA sequence analysis of a library encoded by six cycles of codon addition, optimized to provide unbiased representation. Six cycles of ProxiMAX randomization were undertaken as described in Supplementary Figure S2 (at http://www.biochemsoctrans.org/bst/041/bst0411189add.htm), using right-handed hairpins (Supplementary Table S3 at http://www.biochemsoctrans.org/bst/041/bst0411189add.htm) as donors and an amplicon of pUC19 as the acceptor, with optimized mixtures of 18 codons adjusted to reflect the sequence bias illustrated in Supplementary Figure S2(B). The resulting library was analysed by DNA sequencing, using a MiSeq DNA sequencer according to the manufacturers instructions. Data represent the analysis of 286684 sequences of the correct length, which represented 79.9% of the entire library. Bars represent the frequency of each codon from each cycle of saturation mutagenesis. The broken line depicts the target representation for each codon. Further analysis of the library can be found in ...

ENU mutagenesis is a forward genetics strategy in which random mutagenesis and phenotypic screening is used to identify genes based on the phenotype induced when they are mutated
Our results indicate that growth of HIV in tissue culture in the presence of 5-OH-dC results in the loss of the HIV population and in the accumulation of G → A substitutions. In seven of nine serial experiments, a precipitous decline in viral infectivity occurred over serial passage. This result contrasts with simultaneous incubations carried out in the absence of a nucleoside analog; in a total of 28 control cultures in which the supernatant was serially transferred from 7 to as many as 34 times, the replication of HIV was never abolished, nor was the viral titer diminished by more than 90%. Furthermore, abolishment of HIV titer was not observed with nine other deoxynucleoside analogs so far tested. We detected 97 new 5-OH-dC-induced mutations in 53,000 nucleotides (bottom of Table 3). Assuming that these mutations were evenly distributed throughout an HIV genome containing 10,000 nucleotides, then each proviral DNA obtained immediately prior to lethality contains approximately 18 ...
