Transcriptional repression by the Drosophila giant protein: cis element positioning provides an alternative means of interpreting an effector gradient. (1/8283)

Early developmental patterning of the Drosophila embryo is driven by the activities of a diverse set of maternally and zygotically derived transcription factors, including repressors encoded by gap genes such as Kruppel, knirps, giant and the mesoderm-specific snail. The mechanism of repression by gap transcription factors is not well understood at a molecular level. Initial characterization of these transcription factors suggests that they act as short-range repressors, interfering with the activity of enhancer or promoter elements 50 to 100 bp away. To better understand the molecular mechanism of short-range repression, we have investigated the properties of the Giant gap protein. We tested the ability of endogenous Giant to repress when bound close to the transcriptional initiation site and found that Giant effectively represses a heterologous promoter when binding sites are located at -55 bp with respect to the start of transcription. Consistent with its role as a short-range repressor, as the binding sites are moved to more distal locations, repression is diminished. Rather than exhibiting a sharp 'step-function' drop-off in activity, however, repression is progressively restricted to areas of highest Giant concentration. Less than a two-fold difference in Giant protein concentration is sufficient to determine a change in transcriptional status of a target gene. This effect demonstrates that Giant protein gradients can be differentially interpreted by target promoters, depending on the exact location of the Giant binding sites within the gene. Thus, in addition to binding site affinity and number, cis element positioning within a promoter can affect the response of a gene to a repressor gradient. We also demonstrate that a chimeric Gal4-Giant protein lacking the basic/zipper domain can specifically repress reporter genes, suggesting that the Giant effector domain is an autonomous repression domain.  (+info)

A conserved motif in goosecoid mediates groucho-dependent repression in Drosophila embryos. (2/8283)

Surprisingly small peptide motifs can confer critical biological functions. One example is the WRPW tetrapeptide present in the Hairy family of transcriptional repressors, which mediates recruitment of the Groucho (Gro) corepressor to target promoters. We recently showed that Engrailed (En) is another repressor that requires association with Gro for its function. En lacks a WRPW motif; instead, it contains another short conserved sequence, the En homology region 1 (eh1)/GEH motif, that is likely to play a role in tethering Gro to the promoter. Here, we characterize a repressor domain from the Goosecoid (Gsc) developmental regulator that includes an eh1/GEH-like motif. We demonstrate that this domain (GscR) mediates efficient repression in Drosophila blastoderm embryos and that repression by GscR requires Gro function. GscR and Gro interact in vitro, and the eh1/GEH motif is necessary and sufficient for the interaction and for in vivo repression. Because WRPW- and eh1/GEH-like motifs are present in different proteins and in many organisms, the results suggest that interactions between short peptides and Gro represent a widespread mechanism of repression. Finally, we investigate whether Gro is part of a stable multiprotein complex in the nucleus. Our results indicate that Gro does not form stable associations with other proteins but that it may be able to assemble into homomultimeric complexes.  (+info)

Inhibition of doxorubicin toxicity in cultured neonatal mouse cardiomyocytes with elevated metallothionein levels. (3/8283)

Controversial results have been reported regarding whether metallothionein (MT) functions in doxorubicin (DOX) detoxification in the heart. To determine unequivocally the role of MT in cardiac protection against the toxicity of DOX, ventricular cardiomyocytes isolated from 1- to 3-day neonatal transgenic mice with high levels of cardiac MT and from nontransgenic control animals were applied. On the 6th day of culturing, MT concentrations in the transgenic cardiomyocytes were about 2-fold higher than those in the nontransgenic cells. DOX was added directly into the cultures. Compared with nontransgenic controls, transgenic cardiomyocytes displayed a significant (p <.05) resistance to DOX cytotoxicity, as measured by morphological alterations, cell viability, and lactate dehydrogenase leakage from the cells. This cytoprotective effect of MT correlated with its inhibition of DOX-induced lipid peroxidation. These observations demonstrate unequivocally that elevation of MT concentrations in the cardiomyocytes of 2-fold higher than normal provides efficient protection against DOX toxicity.  (+info)

Human nerve growth factor beta (hNGF-beta): mammary gland specific expression and production in transgenic rabbits. (4/8283)

Transgenic rabbits carrying gene constructs encoding human nerve growth factor beta (hNGF-beta) cDNA were generated. Expression of hNGF-beta mRNA was restricted to the mammary gland of lactating rabbits. Western Blot analysis revealed a polypeptide of 13.2 kDa in the milk of transgenic animals. hNGF-beta was purified from the milk by a two-step chromatographic procedure. Electrospray mass spectroscopy analysis of purified hNGF-beta depicted a molecular weight of 13,261 Da per subunit. The biological activity of the hNGF-beta was tested using PC12W2 cells and cultures of dorsal root ganglion neurons from chicken embryos. Crude defatted milk from transgenic animals and purified hNGF-beta demonstrated full biological activity when compared to commercial recombinant hNGF-beta.  (+info)

Aging-specific expression of Drosophila hsp22. (5/8283)

hsp22 is among the least abundantly expressed Drosophila heat shock (hs) genes during both development and heat stress. In contrast, hsp22 was found to be the most abundantly expressed hs gene during Drosophila aging. During aging, hsp22 RNA was induced 60-fold in the head, with somewhat lower level induction in abdomen and thorax. Induction of the other hs gene RNAs was 150-fold, with particularly abundant expression in eye tissue. Aging-specific induction of hsp22 was reproduced by hsp22:lacZ fusion reporter constructs in transgenic flies. Analysis of specific promoter mutations in transgenic flies indicated that functional heat shock response elements are required for hsp22 induction during aging. Finally, comparison of hsp22 RNA and protein expression patterns suggests that aging-specific expression of hsp22 is regulated at both the transcriptional and the posttranscriptional levels. Aging-specific induction of hsp22 is discussed with regard to current evolutionary theories of aging.  (+info)

Transgenic rabbits as models for atherosclerosis research. (6/8283)

Several characteristics of the rabbit make it an excellent model for the study of lipoprotein metabolism and atherosclerosis. New Zealand White (NZW) rabbits have low plasma total cholesterol concentrations, high cholesteryl ester transfer protein activity, low hepatic lipase (HL) activity, and lack an analogue of human apolipoprotein (apo) A-II, providing a unique system in which to assess the effects of human transgenes on plasma lipoproteins and atherosclerosis susceptibility. Additionally, rabbit models of human lipoprotein disorders, such as the Watanabe Heritable Hyperlipidemic (WHHL) and St. Thomas' Hospital strains, models of familial hypercholesterolemia and familial combined hyperlipidemia, respectively, allow for the assessment of candidate genes for potential use in the treatment of dyslipoproteinemic patients. To date, transgenes for human apo(a), apoA-I, apoB, apoE2, apoE3, HL, and lecithin:cholesterol acyltransferase (LCAT), as well as for rabbit apolipoprotein B mRNA-editing enzyme catalytic poly-peptide 1 (APOBEC-1), have been expressed in NZW rabbits, whereas only those for human apoA-I and LCAT have been introduced into the WHHL background. All of these transgenes have been shown to have significant effects on plasma lipoprotein concentrations. In both NZW and WHHL rabbits, human apoA-I expression was associated with a significant reduction in the extent of aortic atherosclerosis, which was similarly the case for LCAT in rabbits having at least one functional LDL receptor allele. Conversely, expression of apoE2 in NZW rabbits caused increased susceptibility to atherosclerosis. These studies provide new insights into the mechanisms responsible for the development of atherosclerosis, emphasizing the strength of the rabbit model in cardiovascular disease research.  (+info)

Production of donor-derived offspring by transfer of primordial germ cells in Japanese quail. (7/8283)

We transfused concentrated primordial germ cells (PGCs) of the black strain (D: homozygous for the autosomal incomplete dominant gene, D) of quail into the embryos of the wild-type plumage strain (WP: d+/d+) of quail. The recipient quail were raised until sexual maturity and a progeny test of the putative germline chimeras was performed to examine the donor gamete-derived offspring (D/d+). Thirty-one percent (36/115) of the transfused quail hatched and 21 (13 females and 8 males) of them reached maturity. Five females and 2 males were germline chimeras producing donor gamete-derived offspring. Transmission rates of the donor derived gametes in the chimeric females and males were 1.8-8.3% and 2.6-63.0%, respectively. Germline chimeric and the other putative chimeric males were also test-mated with females from the sex-linked imperfect albino strain (AL: d+/d+, al/W, where al indicates the sex-linked imperfect albino gene on the Z chromosome, and W indicates the W chromosome) for autosexing of W-bearing spermatozoa: No albino offspring were born.  (+info)

The Caenorhabditis elegans lim-6 LIM homeobox gene regulates neurite outgrowth and function of particular GABAergic neurons. (8/8283)

We describe here the functional analysis of the C. elegans LIM homeobox gene lim-6, the ortholog of the mammalian Lmx-1a and b genes that regulate limb, CNS, kidney and eye development. lim-6 is expressed in a small number of sensory-, inter- and motorneurons, in epithelial cells of the uterus and in the excretory system. Loss of lim-6 function affects late events in the differentiation of two classes of GABAergic motorneurons which control rhythmic enteric muscle contraction. lim-6 is required to specify the correct axon morphology of these neurons and also regulates expression of glutamic acid decarboxylase, the rate limiting enzyme of GABA synthesis in these neurons. Moreover, lim-6 gene activity and GABA signaling regulate neuroendocrine outputs of the nervous system. In the chemosensory system lim-6 regulates the asymmetric expression of a probable chemosensory receptor. lim-6 is also required in epithelial cells for uterine morphogenesis. We compare the function of lim-6 to those of other LIM homeobox genes in C. elegans and suggest that LIM homeobox genes share the common theme of controlling terminal neural differentiation steps that when disrupted lead to specific neuroanatomical and neural function defects.  (+info)

Because Ras signaling is frequently activated by major hepatocellular carcinoma etiological factors, a transgenic zebrafish constitutively expressing the krasV12 oncogene in the liver was previously generated by our laboratory. Although this model depicted and uncovered the conservation between zebrafish and human liver tumorigenesis, the low tumor incidence and early mortality limit its use for further studies of tumor progression and inhibition. Here, we employed a mifepristone-inducible transgenic system to achieve inducible krasV12 expression in the liver. The system consisted of two transgenic lines: the liver-driver line had a liver-specific fabp10 promoter to produce the LexPR chimeric transactivator, and the Ras-effector line contained a LexA-binding site to control EGFP-krasV12 expression. In double-transgenic zebrafish (driver-effector) embryos and adults, we demonstrated mifepristone-inducible EGFP-krasV12 expression in the liver. Robust and homogeneous liver tumors developed in 100% ...
In the present study, we have successfully generated and characterized a transgenic pig expressing INS-SNAP and demonstrate its suitability for the in vivo labeling of insulin SGs. We provide a strategy to overcome two major limitations of β cell research: the translational gap between rodents and humans and ex vivo experiments for insulin turnover using isolated pancreatic islets. We generated a transgenic pig as a model system, since it closes this translational gap. Pigs are akin to humans in the anatomy of their gastrointestinal tract and the morphology and function of the pancreas (20). Furthermore, it has been demonstrated that the structure and composition of pig pancreatic islets is much closer to human than to rodent islets (25), although some morphological and functional differences in islets between humans and pigs were reported (26, 27). Moreover, the molecular and developmental signatures of pig and human islets and β cells are also more similar to each other than those of human ...

P-glycoproteins can cause multidrug resistance in mammalian tumor cells by active extrusion of cytotoxic drugs. The natural function of these evolutionarily conserved, membrane-bound ATP binding transport proteins is unknown. In mammals, P-glycoproteins are abundantly present in organs associated with the digestive tract. We have studied the tissue-specific expression of Caenorhabditis elegans P-glycoprotein genes pgp-1 and pgp-3 by transformation of nematodes with pgp-lacZ gene fusion constructs in which the promoter area of the pgp genes was fused to the coding region of lacZ. Expression of pgp-1 and pgp-3, as inferred from pgp-lacZ transgenic nematodes, was confined to the intestinal cells. The expression patterns of both genes were virtually indistinguishable. Quantitative analysis of pgp mRNA levels during development showed that pgp-1, -2, and -3 were expressed throughout the life cycle of C.elegans, albeit with some variation indicating developmental regulation. The expression of P-glycoprotein
Claudin 5 as a prominent TJ protein is a consistent feature between the BBB and blood-CSF barrier (Bill and Korzh, 2014). Here we have used this feature to create an in vivo model for real-time analysis of the development, structure and function of the BBB and CP by generating a transgenic zebrafish line that expresses EGFP under the claudin 5a promoter. The high homology and synteny with human, the conservation along the teleost lineage and the previous characterisation of Claudin 5a in zebrafish makes cldn5a a logical candidate (Abdelilah-Seyfried, 2010; Xie et al., 2010; Zhang et al., 2012).. We show that developmental expression of cldn5a:EGFP is restricted to, and starts in both CPs and the midline at 1 dpf, thereby narrowing down the previously shown whole-mount in situ hybridizations (Zhang et al., 2010). The presence of Claudin 5a at the CPs at 1 dpf coincides with the inflation of the ventricles (Zhang et al., 2010, 2012) and corroborates its role in this process. Claudin 5a is crucial ...

The study is the first to document the rise of mutations that make mosquitoes resistant to a gene drive, due to natural selection. These findings will allow researchers to make better predictions of how a gene drive will proceed and to improve the design of future gene drives to decrease the likelihood of resistance.. Tony Nolan adds: Reducing the numbers of mosquito vectors has been the most effective tool to date for the control of malaria, so self-sustaining gene drives designed with this purpose have great potential. However gene drives are not a silver bullet and just like antibiotics can select for resistance in bacteria, gene drives can be susceptible to resistance at their target site. The novelty of this study is not that resistance emerges - we have been planning strategies to deal with this from the start - but that it documents the way it emerges and the way it is selected over generations. This work will help a lot in planning for and managing the emergence of ...

One of the main concerns over gene drive is its potential long‐term effects. The designated effects on the targeted populations will be fast-within a few years-while long‐term effects on ecosystems may take decades to appear and are extremely unpredictable. The time frame of gene drive perfectly fits the economic development strategies dominant today in agribusiness, with a focus on short‐term return on investments and disdain for long‐term issues. The current economical system based on productivity, yields, monoculture, and extractivism [7] is a perfect match for the operating mode of gene drive. In addition, agri‐food industry decision centers are rarely located near the production sites. They will be inclined to disregard the ecological long‐term risks as they only concern local human populations in their exploited lands. Gene drive then becomes an issue of environmental justice.. The scarce use of gene drive, if concerted, cautious and controlled, may not cause any ecological ...

During vertebrate embryogenesis, the cranial neural crest (CNC) forms at the neural plate border and subsequently migrates and differentiates into many types of cells. The transcription factor Snai2, which is induced by canonical Wnt signaling to be expressed in the early CNC, is pivotal for CNC induction and migration in Xenopus. However, snai2 expression is silenced during CNC migration, and its roles at later developmental stages remain unclear. We generated a transgenic X. tropicalis line that expresses enhanced green fluorescent protein (eGFP) driven by the snai2 promoter/enhancer, and observed eGFP expression not only in the pre-migratory and migrating CNC, but also the differentiating CNC. This transgenic line can be used directly to detect deficiencies in CNC development at various stages, including subtle perturbation of CNC differentiation. In situ hybridization and immunohistochemistry confirm that Snai2 is re-expressed in the differentiating CNC. Using a separate transgenic Wnt reporter line
The African Unions High-Level Panel on Emerging Technologies identified gene drive mosquitoes as a priority technology for malaria elimination. The first field trials are expected in 5-10 years in Uganda, Mali or Burkina Faso. In preparation, regional and international actors are developing risk governance guidelines which will delineate the framework for identifying and evaluating risks. Scientists and bioethicists have called for African stakeholder involvement in these developments, arguing the knowledge and perspectives of those people living in malaria-afflicted countries is currently missing. However, few African stakeholders have been involved to date, leaving a knowledge gap about the local social-cultural as well as ecological context in which gene drive mosquitoes will be tested and deployed. This study investigates and analyses Ugandan stakeholders hopes and concerns about gene drive mosquitoes for malaria control and explores the new directions needed for risk governance.

In the past decade, researchers have engineered an array of new tools that control the balance of genetic inheritance. Based on CRISPR technology, such gene drives are poised to move from the laboratory into the wild where they are being engineered to suppress devastating diseases such as mosquito-borne malaria, dengue, Zika, chikungunya, yellow fever and West Nile. Gene drives carry the power to immunize mosquitoes against malarial parasites, or act as genetic insecticides that reduce mosquito populations.. Although the newest gene drives have been proven to spread efficiently as designed in laboratory settings, concerns have been raised regarding the safety of releasing such systems into wild populations. Questions have emerged about the predictability and controllability of gene drives and whether, once let loose, they can be recalled in the field if they spread beyond their intended application region.. Now, scientists at the University of California San Diego and their colleagues have ...
Scientists have issued a call to ensure that the use of gene drives in conservation will only affect local populations. Gene drives promote the inheritance of a particular genetic variant to increase its frequency in a population. In conservation, a gene drive could spread infertility and ultimately eliminate a pest population.
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
A number of other respondents have brought up developments in gene drives (e.g. development of mammalian gene drive systems). In 2018 ETC Group released an overview report on the application of gene drive systems to agriculture (See Forcing the Farm: which we hereby submit for consideration of new developments in the field. Our research show that there is increasing work on application of gene drive systems to agricultural pests (Especially insects and aphids) as well as to applying gene drive as a breeding tool for livestock. To date we cannot identify successful use of CRISPR gene drive systems in plants (although perhaps others on this forum can correct that) or any working examples of so called local or controllable gene drive systems beyond theoretical models. Given that some of these theoretical ideas are advanced in policy fora as if they exist I think it may be important for the moderators in their summary of this forum to also point to and ...

He has led the movement to shine the spotlight, says Marc Lipsitch, an epidemiologist at Harvard University involved in biosafety issues. Its not that common to be at the beginning of your career and already be thinking of the moral, ethical, and policy implications.. A gene drive is a genetic addition made to a mosquito or other organism that is able to spread through a population of animals in the wild and potentially act as a doomsday gadget, driving it out of existence. The technology presents challenges not only because it could extinguish a species but because by its very nature it can spread widely, including as the result of a lab accident..

Gene drive systems distort the rule that there is a 50:50 chance of a gene copy being passed on. This promotes the inheritance of a particular copy of a gene from the parent to offspring. When coupled to a genetic trait that affects an individuals survival or ability to reproduce, it becomes a powerful tool that can be used for population control or even local elimination.
In lab populations of genetically engineered mosquitoes, mutations arose that blocked the gene drive’s spread and restored female fertility.

Public fears and concerns towards transgenic plant or animal have been there for years even though the scientific expects in China, at least, acclaimed that they are safe. The reason why people are afraid of transgenic technology and furthermore reject it is that public people dont know it at all, or have limited understanding.. You must have read lots of articles explaining why transgenic technology is safe, or on the other hand, dangerous. And here I believe current products of transgenic technology in your daily life are safe and healthy, because most of them are protein product indeed. It is the exogenous genes are translocated and expressed in the host, but the outcome is protein according to the known central dogma, hence the protein cannot hybridize with your genome so that you will not be mutated to Rice-Man. No need to panic.. ...

Gene drive is a mechanism that can promote the preferential inheritance of a beneficial genetic trait, thereby increasing its prevalence in a population. A variety of gene drive mechanisms occur in nature that can cause specific genetic elements to spread throughout populations in varying degrees. Researchers have long sought to harness these naturally occurring gene drive mechanisms to prevent the transmission of mosquito or other insect-borne diseases that pose some of societys most intractable public health problems.. ...
Energy homeostasis is accomplished through a highly integrated and redundant neurohumoral system. Recently, novel molecular mediators and regulatory pathways for feeding and body weight regulation have been identified in the brain and the periphery. Because of the multitude and complexity of disturbances in energy intake, expenditure, and partitioning that are associated with obesity, it has been difficult to determine which abnormalities are causative versus less important phenomena that are consequences of the altered neuroendocrine and metabolic milieu. Transgenic technology has provided new opportunities to modify the complex body weight-regulating system and to assess the relative importance of the individual components. Observations of mutant mice have shed new light on the understanding of energy homeostasis equation. Once created, transgenic animal models may be useful in assessing the efficacy or determining the mode of action of potential new therapeutic agents. However, the ...

Currently, there is no other whole-animal reporter for epigenetic regulation established in any vertebrate. The inventors generated this novel zebrafish line using a transgene construct containing dazl gene silencing sequences (CpG island) fused to a destabilized GFPd2 gene driven by the ubiquitously expressing ef1alpha promoter. The resulting transgenic line permits detailed tissue- or cellular- level visualization of dynamic changes in GFPd2 expression in response to changes in DNA methylation or downstream epigenetic regulation in developing or adult animals. GFPd2 is off in the fertilized egg but turns on during early development, peaking at approximately 24 hours post-fertilization, and is then rapidly and ubiquitously silenced. The reporter is off in adults, except in particular stages of germline development in the gonads. Experimental treatments or genetic mutants that interfere with epigenetic silencing result in global or tissue-specific reactivation of GFPd2 expression. The ...

Y1 - 2008/7/1. N2 - Glycosylation of recombinant proteins is of particular importance because it can play significant roles in the clinical properties of the glycoprotein. In this work, the N-glycan structures of recombinant human Factor IX (tg-FIX) produced in the transgenic pig mammary gland were determined. The majority of the N-glycans of transgenic pig-derived Factor IX (tg-FIX) are complex, bi-antennary with one or two terminal N -acetylneuraminic acid (Neu5Ac) moieties. We also found that the N-glycan structures of tg-FIX produced in the porcine mammary epithelial cells differed with respect to N-glycans from glycoproteins produced in other porcine tissues. tg-FIX contains no detectable Neu5Gc, the sialic acid commonly found in porcine glycoproteins produced in other tissues. Additionally, we ...
CRISPR gene drive has recently been proposed as a promising technology for population management, including in conservation genetics. The technique would consist in releasing genetically engineered individuals that are designed to rapidly propagate a desired mutation or transgene into wild populations. Potential applications in conservation biology include the control of invasive pest populations that threaten biodiversity (eradication and suppression drives), or the introduction of beneficial mutations in endangered populations (rescue drives). The propagation of a gene drive is affected by different factors that depend on the drive construct (e.g. its fitness effect and timing of expression) or on the target species (e.g. its mating system and population structure). We review potential applications of the different types of gene drives for conservation. We examine the challenges posed by the evolution of resistance to gene drives and review the various molecular and environmental risks associated with

Our lab studies the alternative splicing of pre-mRNAs. In Drosophila, alternative splicing plays a central role in sex determination. We have been using the sex-determination system to study factors that influence alternative splicing and to determine the mechanisms by which they do so. Several of the proteins we are studying belong to the serine/arginine-rich (SR) family of splicing factors. These proteins usually bind to sequences located within exons, known as exonic splicing enhancers (ESEs) and activate nearby splice sites. We have found that an SR factors can repress splicing when bound within an intron. Using in vitro splicing assays and Drosophila genetics we are determining how splicing activation and repression differ. A second interest of the lab is in genetic models for muscular dystrophy. Recently we have developed a transgenic Drosophila model for facioscapulohumeral muscular dystrophy (FSHD) a poorly understood late-onset disease that affects specific muscle groups in humans. We ...

This study has demonstrated that microparticle bombardment is a simple and efficient technique for generating stable transgenic lines in C. elegans. We have found that a substantial proportion of the transgenic lines generated by microparticle bombardment contain a low number of copies of the transforming DNA integrated into a chromosome, resulting in stable transmission of the transgenic DNA over many generations. A critical factor in the success of this microparticle bombardment transformation strategy is the use of a selectable cotransformation marker to identify rare transformed animals within the population of bombarded animals and their descendants. For the experiments described in this article, we bombarded unc-119 mutants with plasmids containing an unc-119 rescuing fragment and were able to identify transformed animals based on their ability to survive starvation and on their non-Unc phenotype.. In some cases, the unc-119 gene may be an unsuitable cotransformation marker due to ...
The epicardium is the mesothelial outer layer of the vertebrate heart. It plays an important role during cardiac development by, among other functions, nourishing the underlying myocardium, contributing to cardiac fibroblasts and giving rise to the coronary vasculature. The epicardium also exerts key functions during injury responses in the adult and contributes to cardiac repair. In this article, we review current knowledge on the cellular and molecular mechanisms underlying epicardium formation in the zebrafish, a teleost fish, which is rapidly gaining status as an animal model in cardiovascular research, and compare it with the mechanisms described in other vertebrate models. We moreover describe the expression patterns of a subset of available zebrafish Wilms tumor 1 transgenic reporter lines and discuss their specificity, applicability and limitations in the study of epicardium formation ...

In a crowded auditorium at New Yorks Cold Spring Harbor Laboratory in August, Philipp Messer, a population geneticist at Cornell University, took the stage to discuss a powerful and controversial new application for genetic engineering: gene drives.. Gene drives can force a trait through a population, defying the usual rules of inheritance. A specific trait ordinarily has a 50-50 chance of being passed along to the next generation. A gene drive could push that rate to nearly 100 percent. The genetic dominance would then continue in all future generations. You want all the fruit flies in your lab to have light eyes? Engineer a drive for eye color, and soon enough, the fruit flies offspring will have light eyes, as will their offspring, and so on for all future generations. Gene drives may work in any species that reproduces sexually, and they have the potential to revolutionize disease control, agriculture, conservation and more. Scientists might be able to stop mosquitoes from spreading ...

Despite wide academic and commercial interest in the actions of GLP-1, attempts to identify the cellular targets of GLP-1 are hampered by the lack of specificity of antibodies to GLP1R. Our development of a new transgenic mouse model expressing Cre recombinase driven by the glp1r promoter provides an antibody-independent method for the identification and characterization of live cells expressing glp1r, using floxed fluorescent reporter strains. The results illuminate not only which tissues exhibited glp1r fluorescence but also those that did not.. Establishing definitively that the GLP1R protein is produced by all glp1r-fluorescent cells will be important, because our use of Cre recombinase results in a permanent activation of the fluorescent reporters, even in cells that no longer express the receptor as well as in the progeny of cells that have once expressed glp1r. Where neurones were identified, we were able to confirm expression of GLP1R protein by demonstrating functional responsiveness to ...

LONDON (Reuters) - Rodents have joined mosquitoes in the cross-hairs of scientists working on a next-generation genetic technology known as gene drive to control pests.. Researchers in Scotland said on Tuesday they had developed two different ways to disrupt female fertility in rats and mice, building on a similar approach that has already been tested in the lab to eliminate malaria-carrying mosquitoes.. So-called gene drives push engineered genes through multiple generations by over-riding normal biological processes, so that all offspring carry two copies. Usually, animals would receive one copy of a gene from the mother and one from the father.. The technique is extremely powerful but also controversial, since such genetically engineered organisms could have an irreversible impact on the ecosystem.. Concerns about the proliferation of mutant species have led some to call for a gene drive ban, but Bruce Whitelaw of the University of Edinburghs Roslin Institute believes that would be short ...

Naturally occurring mutations involving the nervous system have provided virtually all of our current understanding of the genetic regulation of neural development (Caviness and Rakic, 1978). The difficulty of isolating the corresponding genes, however, has precluded a molecular analysis of these mutants. Insertional mutagenesis, induced by microinjection of DNA into fertilized ova to produce transgenic animals, provides a molecular tag that marks the site of the mutational event. In this article, we describe a transgenic neurological mutation, designated wocko (Wo), which disrupts the development of the inner ear. These mutant mice display a dominant behavioral phenotype that consists of circling, hyperactivity, and head tossing, reminiscent of the shaker/waltzer class of mutants, and they display a recessive homozygous sublethal phenotype. Anatomical analyses showed that both structural and neural components of the vestibular system were disrupted, while analyses of mutant fetuses showed that ...

This is an important issue for anyone involved in using murine models of retinal degeneration. It turns out that contamination of Rd8 mutation in the B6 mice is more wide spread than the C57BL/6N mice. Labs worldwide are going to have to reassess their data due to this mutation and all reviewers will ask about this in the immediate future. The genotyping analysis of a variety of vendor lines is described in this paper by Mary J. Mattapallil, Eric F. Wawrousek, Chi-Chao Chan, Hui Zhao, Jayeeta Roychoudhury, Thomas A. Ferguson, and Rachel R. Caspi. The take home message is that the rd8 mutation is in the C57BL/6N strain which is used worldwide to produce transgenic and knockout models. The implications for non-vision labs are not as clear, but for vision labs, substantial disease can be present unrelated to another specific disease gene and will need to be accounted for.. ...

  • The EU has established a legal framework regulating GM food and feed derived products as well as the release of living GMOs into the environment in order to ensure a high level of protection of human and animal health, and the environment. (
  • EFSA's role is to independently assess and provide scientific advice to risk managers on any possible risks of GMOs for human and animal health and the environment and to propose appropriate measures to mitigate the risks. (
  • The basic assumption of this type of comparative assessment, which is required under current EU legislation for all GMOs submitted for market authorisation, is that food and feed from conventionally-bred animals have a history of safe use and therefore can serve as a baseline for the risk assessment of food and feed derived from GM animals. (
  • As with other genetically modified organisms (GMOs), first genetic engineers must isolate the gene they wish to insert into the host organism. (
  • The basic assumption of the comparative assessment, which is the risk assessment approach for all GMOs laid down in EU legislation, is that non-GM animals serve as a baseline with respect to environmental safety. (
  • [3] In Canada and the USA labeling of GM food is voluntary, [4] while in Europe all food (including processed food ) or feed which contains greater than 0.9% of approved GMOs must be labelled. (
  • In addition to the danger of accidental human ingestion of plants modified to include the Bt gene in their genome, there are some other concerns surrounding GMOs , as well. (
  • 1 This same article claims 'that genetically modified organisms (GMOs) are a major contributor to the sharply deteriorating health of Americans. (

  • It would make a lot of us feel more comfortable, especially with their recent efforts to prevent labeling of genetically engineered food (as well as labels designating a food does not contain GMOs. (
  • According to the World Health Organization , "genetically modified organisms (GMOs) can be defined as organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination. (
  • GMOs are used to produce many medications and genetically modified foods and are widely used in scientific research and the production of other goods. (
  • This should not be confused with the more general way in which "GMO" is used to classify genetically altered organisms, as typically GMOs are organisms whose genetic makeup has been altered without the addition of genetic material from an unrelated organism. (
  • Genetically Modified Organisms, or GMOs, are genetically modified plants, animals, or microorganisms whose genetic information has been modified by DNA-editing methods such as DNA splicing or gene modification. (
  • Within the European Union (EU), the use of genetically modified organisms (GMOs) in food production is not widely applied and accepted. (
  • Genetically modified lactic acid bacteria (GM-LAB) can be considered as a different class of GMOs, and the European Union is preparing regulations for the risk assessment of genetically modified microorganisms. (
  • Since these procedures are not yet implemented, the current risk assessment procedure is shared for GMOs derived from micro organisms, plants, or animals. (
  • Within the United States of America there is not much public resistance towards the use of genetically modified organisms, GMOs ( Box 1 ), in food. (
  • 2 Nonetheless, a careful analysis of both industry and independent studies does demonstrate significant harm to animals fed GMOs. (
  • Plant GMOs are regulated by the US Department of Agriculture's Animal and Plant Health Inspection Service under the Plant Protection Act. (
  • The United States does not have any federal legislation that is specific to genetically modified organisms (GMOs). (

  • Scientists genetically modified a bizarre-looking Mexican salamander, which is considered a transformed Aztec god in ancient mythology. (
  • While clones are exact copies of an animal, genetically engineered animals are manipulated by scientists to bring about a change in their characteristics. (
  • GE animals are created when scientists insert a gene from one species of animal into the DNA of another animal to reprogram some of its characteristics. (
  • Science has made a ton of advancements in changing animal DNA, especially with CRISPR, a genome editing tool that allows scientists to edit genomes with unprecedented precision. (
  • Scientists have across-the-board injected animals like rhesus monkeys, mice, pigs and naked mole rats with glowing jellyfish DNA in various experiments. (

  • Drawing on her father's clinical notes, and the work of scientists like Dr. Don Huber , professor emeritus in plant pathology at Purdue University, Leah Dunham outlines some of the ways in which humans are adding to the suffering of farm animals by feeding them a glyphosate -tainted, GMO diet. (
  • The U.S. government has deemed GM foods safe, but not all scientists agree. (
  • Scientists promise that producing genetically modified foods would solve this problem. (

  • Soon after, scientists were inserting genes into mouse embryos to produce transgenic animals for research. (
  • In relation to organ transplants, scientists have developed a genetically engineered pig with the aim of reducing rejection of pig organs by human recipients Genetically engineered farm animals can be created to enhance food quality 9. (
  • Scientists have created a genetically modified milk that lacks a key protein involved in triggering allergies - an impressive technical feat that won plaudits in the biotechnology world. (
  • Scientists genetically engineered cow cells to suppress the gene for a protein in whey - called beta-lactoglobulin, or BLG - that is present in cow milk but not in human milk. (
  • The calf is now about 11 months old, and the scientists intend to breed it next year so they can analyze the milk more extensively, said study coauthor Stefan Wagner, an animal geneticist at AgResearch. (
