TY - JOUR. T1 - The embryonic lethality of homozygous lethal yellow mice (A(y)/A(y)) is associated with the disruption of a novel RNA-binding protein. AU - Michaud, E. J.. AU - Bultman, S. J.. AU - Stubbs, L. J.. AU - Woychik, R. P.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - Lethal yellow (A(y)) is a mutation at the mouse agouti (a) locus that is associated with an all-yellow coat color, obesity, diabetes, tumors in heterozygotes, and preimplantation embryonic lethality in homozygotes. Previously, we cloned and characterized the wild-type agouti gene and demonstrated that it expresses a 0.8-kb mRNA in neonatal skin. In contrast, A(y) expresses a 1.1-kb transcript that is ectopically overexpressed in all tissues examined. The A(y) mRNA is identical to the wild-type a transcript for the entire coding region, but the 5-untranslated sequence of the a gene has been replaced by novel sequence. Here, we demonstrate that the novel 5 sequence in the A(y) mRNA corresponds to the 5-untranslated sequence of ...

The agouti gene regulates the differential production of eumelanin (black or brown) and phaeomelanin (yellow) pigment granules by melanocytes in the hair follicles of mice. The original nonagouti (a) allele, which confers a predominantly black coat color, has been shown to revert to two other more dominant agouti alleles, black-and-tan (a(t)) and white-bellied agouti (Aw), with an exceptionally high frequency. The a(t) and Aw alleles confer phenotypes in which the pigmentation is not uniformly distributed over the dorsal and ventral surfaces of the animal; in both cases the ventral surface of the animal is markedly lighter than the dorsal surface due to an increase in phaeomelanin production. To understand the unusually high reversion rate of a to a(t) or Aw, and to decipher the molecular events associated with the different pigmentation patterns associated with these three agouti alleles, we have characterized a, a(t) and Aw at the molecular level. Here, we report that insertions of 11, 6,

Repetitive elements (REs) have the potential to actively interfere with the normal transcription of genes located in their immediate vicinity along the chromosome. The Mammalian Genome Group originally described one of the first instances of how a RE can interfere with the normal expression of a gene. In this case, a promoter on the long terminal repeat (LTR) of an an intracisternal A particle (IAP) element, located within an intron, was demonstrated to hijack the normal regulated expression of the agouti gene in the skin. The finding was ultimately shown to result in the ubiquitous expression of the agouti protein which, in turn, was associated with a yellow coat color, obesity, and type II diabetes in mice (1, 2). Most notably, the group also previously showed that the ability of the IAP to hijack the expression of agouti is dependent upon the epigenetic status of the IAP: methylation of the IAP to suppress its ability to influence agouti expression (2). Moreover, other groups have ...

dentification of the fundamental polypeptide difference between yellow (Ay/-, Avy/-) and non-yellow mice is important for biomedical research because of the influence of the yellow genotype on normal and neoplastic growth and obesity. The complexity of the yellow mouse syndrome makes attainment of this objective dependent on the separation of those pleiotropic enzyme differences which are secondary, and depend on the background genome, from those which are primary, and depend primarily on the agouti locus genotype.-Four of nine hepatic enzyme activities assayed simultaneously differed between eight-week-old yellow (Ay/-, Avy/-) and non-yellow (A/-, a/a) male inbred and F1 hybrid mice. Among these four, only cytoplasmic malic enzyme activity was elevated in all yellow mice, as compared with the non-yellow sibs, regardless of background genome. Glucokinase, serine dehydratase, and tyrosine α-ketoglutarate transaminase activities were also changed in yellow mice, but these alterations depended ...

Most Agouti viable yellow (A vy ) mice display constitutive expression of agouti protein, which acts as an inverse agonist at the melanocortin receptor 4 (Mc4r), resulting in adult-onset obesity as well as an altered sensitivity to some drugs of abuse. We investigated the influence of excessive agouti expression on open-field locomotor response to daily 0.5 mg/kg (-)-freebase nicotine injections in 27 early adolescent and 27 young adult male A vy /a and a/a mice, and assessed the effects of nicotine administration (0.5 mg/kg) followed by open-field testing on serum corticosterone levels in a separate group of 25 young adult male A vy /a and a/a mice. Young adult A vy /a mice displayed pronounced nicotine-induced hypolocomotion (a 24% reduction in distance traveled) compared to their a/a littermates. Early adolescent A vy

Production of yellow versus black pigment in dogs is controlled by three genes: Mc1r, Agouti, and CBD103. Dogs carrying wild-type alleles for all three genes have a yellow coat resulting from Agouti antagonism of Mc1r signaling in melanocytes (yellow Great Dane, top). Dogs carrying a loss-of-function mutation at Mc1r have a yellow coat, regardless of their genotype at Agouti or CBD103 (yellow Labrador Retriever, middle). Dogs carrying wild-type alleles for Mc1r and Agouti, together with the dominant black allele of CBD103 (KB) have a black coat resulting from the interaction between a beta-defensin and Mc1r (black Curly Coated Retriever, bottom ...

Much of the modern understanding of equine coat color genetics is owed to the work of Dr. Ann T. Bowling of the University of California, Davis and of Dr. Phillip Sponenberg of Virginia Polytechnic Institute. Modern discussions of horse coat color genetics are based on the distinction between red and non-red coats, a factor determined by a single gene. More detailed discussions of coat color all refer to the differing effects of separate genes on these base coat colors.[3] Coat color alleles affect melanin, the pigment or coloring of the coat. There are two chemically distinct types of melanin: pheomelanin, which is perceived as red to yellow color, and eumelanin, is perceived as brown to black. All coloration genes in mammals affect either the production or distribution of these two chemicals. Alleles affecting melanocytes (pigment cells) do not alter the pigment chemicals themselves but rather by acting on the placement of pigment cells produce distinct patterns of unpigmented pink skin ...

Perhaps one of the most interesting aspects of the melanocortin system is that it has two endogenous antagonists, agouti and AGRP. These proteins are unique in that no inhibitory proteins have been identified for any of the seven-transmembrane receptor family. Agouti and AGRP are paracrine signaling molecules, which are endogenous antagonists of the MCRs (13). Of physiological significance, agouti and AGRP have MCR subtype selectivity (Table 1). Interestingly, agouti and AGRP both have a cysteine-rich COOH-terminal domain. Although the structure of agouti has not been resolved, nuclear magnetic resonance studies demonstrate that the cysteine residues in AGRP adopt a structural motif called an inhibitor cystine knot (32). This motif is common to invertebrate toxins, but in mammals this structure is unique to AGRP and, presumably, agouti. Another commonality is that agouti and AGRP have both been shown in vitro to be inverse agonists (33). Thus they have the potential in vivo to regulate their ...

Mice harboring the hCD2-iCre transgene have the human CD2 promoter and locus control region (LCR) directing expression of an optimized variant of Cre recombinase (iCre) to T cells and B cells (all B cell and T cell progenitors) and mice may be useful for generating conditional mutations in T cells and B cells. Because of the integration site of the transgene, the hCD2-iCre transgene is linked to the agouti coat color genes.

This study examined the effect of glutathione on the in vivo depigmenting potency of N-acetyl-4-S-cysteaminylphenol (N-acetyl-4-S-CAP) in black and yellow mice after multiple intraperitoneal injections on 10 consecutive days. In black mice (C57BL/6J, a/a), N-acetyl-4-S-CAP showed dose-dependent depigmenting potency (0.5, 1.0, and 2.0 mmol/kg), which was in parallel to the tissue eumelanin content (98%, 28%, and 3% of controls, respectively) and to the tissue glutathione content (94%, 85%, and 76%, respectively). In lethal yellow mice (C57BL/6J, Ay/a), only a dose of 2.0 mmol/kg showed the color change of hair to dark, not to white as seen in black mice. This was reflected by the decrease of pheomelanin content (56%) and the increase of eumelanin content (28% of black mice). The simultaneous administration of N-acetyl-cysteine, which up-regulated glutathione content, completely abolished the depigmenting potency of N-acetyl-4-S-CAP, whereas administration of buthionine sulfoximine, which depleted ...

Results: One week after the AMI operation, serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities in both AMI and N+AMI group were significantly higher than those in the sham group, but there were no significant differences between AMI and N+AMI mice. Contents of inducible nitric oxide synthase (iNOS) in the noninfarct area of the left ventricle in the N+AMI mice were significantly higher than those in the AMI mice, with no difference in the infarct area. Coagulation necrosis in the cardiomyocytes was observed in both AMI and N+AMI mice; however, it was less severe in the N+AMI mice. Western blot analyses showed that nitrite pretreatment resulted in up-regulation of antiapoptotic factors Bcl-2 and p21waf1/cip1 signal proteins, but down-regulation of the proapoptotic factor Bax signal protein. Furthermore, nitrite pretreatment also showed significant alleviation of AMI-induced signal protein expressions of inflammatory factors of NF-KB and oxidative factors of Hsp 70 and HO-1 ...

For example, some mice have an epigenetic modification that alters the expression of the agouti gene: adult mice that are affected are yellow-furred, obese and diabetic, while genetically identical mice are sleek, brown-furred and healthy. This epigenetic modification is inherited from the mother, and can be affected by the chemicals the mother is exposed to during pregnancy, such as the nutritional supplements folic acid and vitamin B12, and bisphenol A, a chemical used in the manufacture of plastics. And its not just the mothers diet and chemical exposure during pregnancy that affects expression of agouti - epigenetic changes caused by diet can be passed on to grandchildren.. And while most of the research has focused on mice, for obvious ethical and practical reasons, data has been emerging that humans are similarly affected. For example, the detailed records of births, deaths and harvests in Sweden have been used to look at how the availability of food affects lifespan of subsequent ...

Extension Series (E): Em, E, Ebr, e. But newer reseach indicates that dominant black As does not belong in the Agouti series at all - and this is consistent with other mammals which also share the Agouti series, none of which has a dominant phaeomelanin suppressor like As at the top of the series. This research also indicates that brindle (Ebr in the old system) and dominant black form a separate series of at least 3 alleles, which we will call K (for blacK): K=dominant black, kbr=brindle, k=normal. Finally, we have removed Em (black mask) and placed it in its own separate series which we call Super Extension (Se); again this agrees with current research.. So in this genetic configuration, we have used ...

Though Oriolus chinensis (above) would win hands down in terms of sporting a bright, yellow coat, its common name is the Black-naped Oriole. Of course, in its juvenile state, the back of its head (or nape) is still a sulphuric yellow. Talk about being misleading. :) Anyway, this was another bird that kicked me into a frenzy. I still remembered catching sight of it initially at the top of the Macarthur Palms (read as Mac-Arthur) as it was in the process of picking and swallowing the ripe fruits. Skittish by a sudden human presence, it immediately flew down to a drain below. By this time, I was tingling with excitement as I was pretty certain I have never seen the likes of this bird in my life (the truth wasnt revealed till I showed the picture to LK). By then I was straining to either stay in the spot to observe the bird or go back into my friends room and grab my camera, I decided on the latter whilst cursing (blast it, of all times my camera wasnt there when I needed it) and hoping ...

Cytokines are a diverse groups of small signal proteins that act like hormones to turn on genes in blood cells and cells of the immune system. In COVID-19 the production of cytokines can be over-stimulated to produce a cytokine storm that activates immune cells producing all kinds of severe, sometimes lethal, effects. There are dozens of different cytokines but they all act in a similar manner. Each one binds to a receptor on the membrane of a target cell and this stimulates the cytoplasmic side of the receptor to activate a transcription factor that enters the nucleus and turns on a specific set of genes. The activation step requires phosphorylation just like dozens of other signalling pathways. (See Morris et al. (2018) for a recent review ...

The agouti signaling protein (ASIP or the agouti protein) and its neuropeptide homolog the agouti-related protein (AgRP) are paracrine signaling molecules that act as inverse agonists at distinct subsets of melanocortin receptors. ASIP antagonizes the binding of α-melanocyte stimulating hormone (α-MSH) to melanocortin 1 receptor (MC1R), switching melanin synthesis from eumelanin (black/brown) to phaeomelanin (red/yellow). The effect of ASIP on pigment type-switching is responsible for a variety of coat color patterns accross a broad range of mammalian species. AgRP is involved in energy balance and acts normally at the MC3R and MC4R to control body weight regulation and metabolism [1,2]. Sequence similarity between ASIP and AgRP is confined to their Cys-rich C-terminal domains, which are also responsible for melanocortin receptor binding activity in vitro. Approximately 40 residues in length, there are ten cysteine residues in the C-terminal domain that form a network of five disulfide bonds ...

Interferon-gamma (IFN-gamma) and interleukin-17 (IL-17) have been involved in the pathogenesis of experimental autoimmune encephalomyelitis (EAE). We have carried out a follow-up study of the expression and production of these cytokines, as well as of cells expressing these cytokines during the course of active EAE in Dark Agouti (DA) rats. As a result, IL-17, but not IFN-gamma expression and production had the peak value in draining lymph nodes (DLN) during the induction phase of the disease, and in spinal cords (SC) at the onset of clinical signs of the disease, and then declined toward the resolution of the disease. Also, a significant proportion of IFN-gamma/IL-17 double-positive cells was observed in SC of DA rats in active EAE. Importantly, the highest proportion of IL-17 single positive and double-positive cells, but not of IFN-gamma single positive cells, was observed at the onset of the disease. The observed difference in the kinetics of IFN-gamma and IL-17 expression during active EAE ...

Chinchilla in most small animals is a c-locus mutation, meaning that it is a partial albino. In rats the situation is quite difficult, and chinchilla is a fairly difficult variety to breed due to the interaction of marking and colour genes needed in order to produce the perfect chinchilla.. Colour-wise, black pigment on a chinchilla rat is exactly the same as an agouti, but the unique colour comes from the removal of all of the yellow pigment. This makes the bands that would be red on an agouti a white or pearl-white colour, so the rat becomes a combination of grey and black hairs ticked with white, with black guard hairs.. The genes for removing the yellow pigment in chinchillas only work in combination with a gene for white markings, which is why chinchilla rats are a marked variety. A chinchilla rat has one copy of this spotting gene - a rat with two copies is either never born, or born as a black eyed white type which dies very young.. Genetics: Agouti, with at least one copy of the fading ...

A bit of history: The demise of the inkwell began in the 1880s, with the invention of the first practical fountain pen by Lewis Waterman. Not only did Watermans writing instrument carry its own supply of ink, the flow of the ink was emitted in a regular, controllable stream. In 1939, Liszlo Biro, a proofreader from Hungary patented the first ballpoint pen. Eighteen years later the U.S. Post Office would replace all straight pens and inkwells with the much improved ballpoint. After centuries of use, the inkwell virtually disappeared from daily life. Inkwells also illustrate the class distinctions ...

The first group, published in Nature, included a dominant black coat color allele into their stem cells, then placed the embryos into white mice, giving them an initial visual check. If the young were black, they had to have come from the stem cells. When the first black baby mouse was born, further DNA tests confirmed that Tiny (as he was named) had indeed arisen from the iPS line. It took them over 250 developing embryos before they achieved a live mouse. Out of the 37 stem cell lines created, 3 produced live mice, and out of a total of 624 injected embryos from the best cell line, they got only 22 live births. Thats a success rate of only 3.5 ...

There are many varieties of guinea pig, each with different coat types and colours. The four main breeds are: 1. English Self, which is one colour all over with a smooth, short coat. There are 8 different colours: Self Black, Pink-eyed White, Black-eyed White, Self Cream (champagne cavies), Self Golden, Self Chocolate, Self Beige, Self Lilac (pale dove grey).. 2. Dutch, Agouti, Himalayan, Roan, Dalmatian and Tortoiseshell & White are all smooth marked guinea pigs. Dutch guineas are white with a coloured rump and cheek patches of the same colour, leaving a white blaze down the nose. Agouti guineas are ticked, they have two different coloured bands in their hair, making them look speckled. Himalayan guineas are a bit like Siamese cats, with creamy bodies and brown or black noses and feet. Babies are born pure white and the markings develop later on. Roan guineas are spotty, with mixed black and white hairs and a black head and feet. Dalmatianguineas are also spotty, but have Dutch-type head ...

After electroporation of your construct and selection of ES clones we will give you duplicate 96-well plates containing 5-10ug of DNA from each of about 200 clones. You will analyze these clones using PCR and/or southern blot to determine which have homologously recombined in the correct location on the chromosome (targeted). Usually 1-20% of the clones will be targets.. We can karyotype your best lines, and then inject two of these lines of ES cells into blastocysts. We usually inject 8-12 ES cells (129-derived or 129/Bl6-derived which are agouti in color) into each C57Bl6 (black in color) blastocyst. We implant about 100 injected blastocysts into several pseudopregnant foster mothers over the course of one week of injections. Of the pups born, we generally get at least 5 good chimeric males that are at least 80% agouti. This indicates that most of the mouse is made up of the injected targeted ES cells rather than the black host.. We then breed these chimeric males back to C57Bl6 females to ...

The interplay of gene flow, genetic drift, and local selective pressure is a dynamic process that has been well studied from a theoretical perspective over the last century. Wright and Haldane laid the foundation for expectations under an island-continent model, demonstrating that an island specific beneficial allele may be maintained locally if the selection coefficient is larger than the rate of migration of the ancestral allele from the continent. Subsequent extensions of this model have provided considerably more insight into the conditions under which such a beneficial allele may be maintained, lost, or fixed. Yet, connecting theoretical results with empirical data has proven challenging, owing to a lack of information on the relationship between genotype, phenotype, and fitness. Here, we examine the demographic and selective history of deer mice in and around the Nebraska Sand Hills, a system in which variation at the Agouti locus affects cryptic coloration that in turn affects the ...

The interior is finished in a stunning gloss varnished combination of mahogany trim and Swiss pear wood panels. The cabin sole is gloss varnished teak with Swiss pear wood stripes and the overhead is white laminate bonded to Divinycell closes cell foam (for acoustic and thermal insulation) and held in place with removable mahogany battens..

The large raised saloon windows have custom Oceanair pleated shades housed in custom mahogany valences below windows. Natural ventilation is plentiful through the opening portlights and hatches as well as the dorades bringing fresh air into the boat even when the hatches ...

Instead of masking the effects of another gene, a gene can modify the expression of a second gene. In mice, coat color is controlled by the B gene. The B allele conditions black coat color and is dominant to the b allele that produces a brown coat. The intensity of the color, either black or brown is controlled by another gene, the D gene. At this gene, the dominant D allele controls full color whereas the recessive d allele conditions a dilute or faded expression of the color expression at the B gene. Therefore, if a cross is made among mice that are BdDd, the following phenotypic distribution will be seen: ...

Obesity alters adipose tissue metabolic and endocrine function and leads to an increased release of fatty acids, hormones, and proinflammatory molecules that contribute to obesity associated complications. To further characterize the changes that occur in adipose tissue with increasing adiposity, we profiled transcript expression in perigonadal adipose tissue from groups of mice in which adiposity varied due to sex, diet, and the obesity-related mutations agouti (Ay) and obese (Lepob). We found that the expression of 1,304 transcripts correlated significantly with body mass. Of the 100 most significantly correlated genes, 30% encoded proteins that are characteristic of macrophages and are positively correlated with body mass. Immunohistochemical analysis of perigonadal, perirenal, mesenteric, and subcutaneous adipose tissue revealed that the percentage of cells expressing the macrophage marker F4/80 (F4/80+) was significantly and positively correlated with both adipocyte size and body mass. ...
