Glucocorticoids mediate the enhanced expression of intestinal type II arginase and argininosuccinate lyase in postweaning pigs. (1/123)

Arginine metabolism is enhanced in the small intestine of weanling pigs, but the molecular mechanism(s) involved is not known. The objectives of this study were to determine the following: 1) whether glucocorticoids play a role in induction of intestinal arginine metabolic enzymes during weaning; 2) whether the induction of enzyme activities was due to increases in corresponding mRNA levels; and 3) the identity of the arginase isoform(s) expressed in the small intestine. Jejunum was obtained from 29-d-old weaned pigs that were or were not treated with 17-beta-hydroxy-11beta-(4-dimethylaminophenyl)17alpha-(prop- 1-ynyl)es tra-4,9-dien-3-one (RU486, an antagonist of glucocorticoid receptors), or from age-matched suckling pigs. Activities and mRNA levels for type I and type II arginases, argininosuccinate synthase (ASS) and argininosuccinate lyase (ASL) were determined. Activities of arginase, ASL and ASS increased by 635, 56 and 106%, respectively, in weanling pigs, compared with suckling pigs. RU486 treatment attenuated the increase in arginase activity by 74% and completely prevented the ASL induction in weanling pigs, but had no effect on ASS activity. Pig intestine expresses both type I and type II arginases. On the basis of immunoblot analyses, there was no significant difference in levels of intestinal type I arginase among these three groups of pigs, indicating that changes in arginase activity were due only to type II arginase. The mRNA levels for type II arginase and ASL increased by 135 and 198%, respectively, in weanling pigs compared with suckling pigs, and this induction was completely prevented by RU486. In contrast, ASS mRNA levels did not differ between suckling and weanling pigs. These results suggest that intestinal type II arginase, ASS and ASL are regulated differentially at transcriptional and post-translational levels and that glucocorticoids play a major role in the induction of type II arginase and ASL mRNAs in the small intestine of weanling pigs.  (+info)

Competitive inactivation of a double-strand DNA break site involves parallel suppression of meiosis-induced changes in chromatin configuration. (2/123)

In Saccharomyces cerevisiae, DNA double-strand breaks (DSBs) initiate meiotic recombination at open sites in chromatin, which display a meiosis-specific increase in micrococcal nuclease (MNase) sensitivity. The arg4 promoter contains such a DSB site. When arg4 sequences are placed in a pBR322-derived insert at HIS4 (his4 :: arg4 ), the presence of strong DSB sites in pBR322 sequences leads to an almost complete loss of breaks from the insert-borne arg4 promoter region. Most of the MNase-sensitive sites occurred at similar positions in insert-borne and in normal ARG4 sequences, indicating that hotspot inactivation is not a consequence of changes in nucleosome positioning. However, a meiosis-specific increase in MNase hypersensitivity was no longer detected at the inactive insert-borne arg4 DSB site. Elimination of pBR322 sequences restored DSBs to the insert-borne arg4 promoter region and also restored the meiotic induction of MNase hypersensitivity. Thus, the meiotic induction of MNase hypersensitivity at the DSB sites is suppressed and activated in parallel to DSBs themselves, without changes in the underlying DNA sequence or nucleosome positioning. We suggest that meiosis-specific changes in chromatin at a DSB site are a signal reflecting a pivotal step in DSB formation.  (+info)

Use of a recombination reporter insert to define meiotic recombination domains on chromosome III of Saccharomyces cerevisiae. (4/123)

In Saccharomyces cerevisiae, meiotic recombination is initiated by DNA double-strand breaks (DSBs). DSBs usually occur in intergenic regions that display nuclease hypersensitivity in digests of chromatin. DSBs are distributed nonuniformly across chromosomes; on chromosome III, DSBs are concentrated in two "hot" regions, one in each chromosome arm. DSBs occur rarely in regions within about 40 kb of each telomere and in an 80-kb region in the center of the chromosome, just to the right of the centromere. We used recombination reporter inserts containing arg4 mutant alleles to show that the "cold" properties of the central DSB-deficient region are imposed on DNA inserted in the region. Cold region inserts display DSB and recombination frequencies that are substantially less than those seen with similar inserts in flanking hot regions. This occurs without apparent change in chromatin structure, as the same pattern and level of DNase I hypersensitivity is seen in chromatin of hot and cold region inserts. These data are consistent with the suggestion that features of higher-order chromosome structure or chromosome dynamics act in a target sequence-independent manner to control where recombination events initiate during meiosis.  (+info)

(CA/GT)(n) microsatellites affect homologous recombination during yeast meiosis. (5/123)

One of the most common microsatellites in eukaryotes consists of tandem arrays of the dinucleotide GT. Although the study of the instability of such repetitive DNA has been extremely fruitful over the last decade, no biological function has been demonstrated for these sequences. We investigated the genetic behavior of a region of the yeast Saccharomyces cerevisiae genome containing a 39-CA/GT dinucleotide repeat sequence. When the microsatellite sequence was present at the ARG4 locus on homologous chromosomes, diploid cells undergoing meiosis generated an excess of tetrads containing a conversion of the region restricted to the region of the microsatellite close to the recombination-initiation double-strand break. Moreover, whereas the repetitive sequence had no effect on the frequency of single crossover, its presence strongly stimulated the formation of multiple crossovers. The combined data strongly suggest that numerous recombination events are restricted to the initiation side of the microsatellite as though progression of the strand exchange initiated at the ARG4 promoter locus was impaired by the repetitive sequence. This observation corroborates in vitro experiments that demonstrated that RecA-promoted strand exchange is inhibited by CA/GT dinucleotide tracts. Surprisingly, meiotic instability of the microsatellite was very high (>0.1 alterations per tetrad) in all the spores with parental and recombinant chromosomes.  (+info)

Guanidine hydrochloride induced reversible dissociation and denaturation of duck delta2-crystallin. (6/123)

The tetrameric delta2-crystallin from duck lens exhibits a reversible dissociation-denaturation process in solutions containing guanidine hydrochloride (GdnHCl). Sigmoidal or biphasic curves for the dissociation/denaturation processes, obtained using different methods of structural analysis, as a function of GdnHCl concentration were not coincidental with each other. delta2-crystallin in 0.91 M GdnHCl existed primarily as a monomer, which had no endogenous argininosuccinate lyase activity. After dilution of the GdnHCl-treated protein, the monomers reassociated into tetramers with concomitant recovery of enzyme activity. The sigmoidal recovery of enzyme activity demonstrates a cooperative hysteretic reactivation process. When the concentration of GdnHCl was higher than 1.2 M, various partially unfolded soluble forms of delta2-crystallin were produced from the dissociated monomers as shown by size-exclusion chromatography. The formation of a partially unfolded intermediate during the dissociation-denaturation process is proposed.  (+info)

Regulation of diaphragmatic nitric oxide synthase expression during hypobaric hypoxia. (7/123)

Nitric oxide (NO) is normally synthesized inside skeletal muscle fibers by both endothelial (eNOS) and neuronal (nNOS) nitric oxide synthases. In this study, we evaluated the influence of hypobaric hypoxia on the expression of NOS isoforms, argininosuccinate synthetase (AS), argininosuccinate lyase (AL), and manganese superoxide dismutase (Mn SOD) in the ventilatory muscles. Rats were exposed to hypobaric hypoxia ( approximately 95 mmHg) from birth for 60 days or 9-11 mo. Age-matched control groups of rats also were examined. Sixty days of hypoxia elicited approximately two- and ninefold increases in diaphragmatic eNOS and nNOS protein expression (evaluated by immunoblotting), respectively, and about a 50% rise in diaphragmatic NOS activity. In contrast, NOS activity and the expression of these proteins declined significantly in response to 9 mo of hypoxia. Hypoxia elicited no significant alterations in AS, AL and Mn SOD protein expression. Moreover, the inducible NOS (iNOS) was not detected in normoxic and hypoxic diaphragmatic samples. We conclude that diaphragmatic NOS expression and activity undergo significant adaptations to hypobaric hypoxia and that iNOS does not participate in this response.  (+info)

Accumulation of arginine precursors in Escherichia coli: effects on growth, enzyme repression, and application to the forward selection of arginine auxotrophs. (8/123)

The accumulation or ornithine, citrulline, and possibly acetylornithine by Escherichia coli K-12 arginineless mutants provided with acetylarginine as source of arginine causes severe growth inhibition. This occurs under conditions where comparable derivatives of E. coli W (Bollon and Vogel, 1973) show little or no growth inhibition. The same conditions, which have been reported to cause noncorrelative synthesis of acetylornithinase and argininosuccinase in E. coli W (Bollon and Vogel, 1973), do not alter the correlative pattern of enzyme synthesis observed in E. coli K-12. Moreover, previously reported effects of ornithine and citrulline on repression of the arginine regulon in E. coli W are not observed in the K-12 strains examined. The bearing of these observations on possible differences between the mechanism of enzyme repression operating in the two types of strains cannot yet be fully evaluated; it is, however, clear that considerable care should be exercised before extrapolating the results obtained with one type of strain to the other one. The particularly strong inhibition of acetylarginine utilization exerted by ornithine in E. coli K-12 allows the forward selection of several classes of arginine auxotrophs from strains deficient in carbamoylphosphate biosynthesis and thus capable of ornithine accumulation. Possible applications of this technique to the genetic analysis of the bipolar argECBH operon are discussed.  (+info)

Pathogenic variants in the argininosuccinate lyase (|i|ASL|/i|) gene have been shown to cause argininosuccinate lyase deficiency (ASLD); therefore, sequencing analysis offers advantages for prenatal testing and counseling in families afflicted with this condition. Here, we performed a genetic analysis of an ASLD patient and his family with an aim to offer available information for clinical diagnosis. The research subjects were a 23-month-old patient with a high plasma level of citrulline and his unaffected parents. Whole-exome sequencing identified potential related|i| ASL|/i| gene mutations in this trio. Enzymatic activity was detected spectrophotometrically by a coupled assay using arginase and measuring urea production. We identified a novel nonsynonymous mutation (c.206A>G, p.Lys69Arg) and a stop mutation (c.637C>T, p.Arg213∗) in|i| ASL|/i| in a Chinese Han patient with ASLD.

Argininosuccinate synthase 1 is an intrinsic Akt repressor transactivated by p53 | Science AdvancesArgininosuccinate synthase 1 is an intrinsic Akt repressor transactivated by p53 | Science Advances
Although accumulating evidence highlights the importance of p53-mediated metabolism in tumor suppression (2, 47), the mechanisms by which p53 drives dynamic nutrient status in harmony with canonical p53 functions remain poorly understood. Here, we show that p53 activates the penultimate step of de novo arginine synthesis pathway through the direct induction of the rate-limiting enzyme ASS1. Furthermore, we demonstrate that ASS1 deficiency induced anomalous Akt phosphorylation, resulting in rendering cells more susceptible to genotoxic stress.. Although we have demonstrated that p53 drives the de novo arginine synthesis pathway via ASS1 induction under genotoxic conditions, argininosuccinate lyase (ASL), which directly produces arginine from argininosuccinate, was not induced by p53 in HCT116 cells. These results suggest that ASS1 is the sole node connecting p53 to the de novo arginine synthesis pathway. Because ASS1 is a rate-limiting enzyme of the de novo arginine synthesis pathway, ASS1 ...

Pegylated arginine deiminase (ADIPEG20) which degrades arginine to citrulline and ammonia has been used clinically and partial responses and stable disease have been noted with minimal toxicity. In order to improve the therapeutic efficacy of ADI-PEG20, we have combined ADI-PEG20 with a DNA damaging agent, cisplatin. We have shown that the combination of the two drugs together significantly improved the therapeutic efficacy when compared to ADI-PEG20 alone or cisplatin alone in 4 melanoma cell lines, regardless of their BRAF mutation. ...

Argininosuccinate synthetase (ASS), an integral enzyme to synthesize arginine is usually down regulated in many tumors including hepatocellular carcinoma (HCC). only occurs in SNU398 and SNU387, and not in HepG2 and Huh-1 (ASS(+)) cells, purchase EPZ-5676 and it is partly because of reduced anti-apoptotic protein X-linked inhibitor of apoptosis proteins (XIAP), myeloid leukemia cell differentiation proteins (Mcl-1) and B-cell lymphoma-2 (Bcl-2). Significantly, insufficient ASS also affects important enzymes in pyrimidine synthesis (carbamoyl-phosphate synthetase2, aspartate transcarbamylase and dihydrooratase (CAD) and thymidylate synthase (TS)) and malate dehydrogenase-1 (MDH-1) in TCA routine. ADI-PEG20 treatment reduced these enzymes and produced them more purchase EPZ-5676 susceptible to 5-FU. Transfection of ASS restored these enzymes and abolished the awareness to mixture and ADI-PEG20 treatment. General, our data claim that ASS affects multiple enzymes involved with 5-FU sensitivity. ...

For example, the fact that methylation-dependent silencing of argininosuccinate synthetase (ASS1) [40], a rate-limiting enzyme involved in the biosynthesis of arginine, has been implicated in therapeutic resistance in several cancer types including renal cell carcinoma, hepatocellular carcinoma, malignant melanoma, glioblastoma multiforme, and platinum-resistant epithelial. ovarian cancer suggests a role for demethylating agents in these ASS1 drug-resistant find more cancers [41]. Nevertheless, despite their current nonspecific promiscuity, epigenetic agents may act on most or all tumor types, since aberrant methylation and deacetylation patterns are a hallmark of cancer cells. In particular, several of the anticancer agents described in this review activate and upregulate p53, which itself affects multiple targets [19]. Following genotoxic stress. in response to traditional therapeutic strategies such as cisplatin, doxorubicin, 5-fluorouracil, fludarabine, mitoxantrone, etoposide, or X-ray ...

Argininosuccinic Aciduria - NORD (National Organization for Rare Disorders)Argininosuccinic Aciduria - NORD (National Organization for Rare Disorders)
Treatment may require the coordinated efforts of a team of specialists. Pediatricians, neurologists, geneticists, dieticians, and physicians who are familiar with metabolic disorders may need to work together to ensure a comprehensive approach to treatment. Occupational, speech language, and physical therapists may be needed to treat children with developmental disabilities. Genetic counseling is recommended for affected individuals and their families.. The treatment of argininosuccinic aciduria is aimed at preventing excessive ammonia from being formed or from removing excessive ammonia during a hyperammonemic episode. Long-term therapy combines dietary restrictions and the stimulation of alternative methods of converting and excreting nitrogen from the body (alternative pathways therapy).. Dietary restrictions in individuals with argininosuccinic aciduria are aimed at limiting the amount of protein intake to avoid the development of excess ammonia. However, enough protein must be taken in by ...

Argininosuccinate lyase deficiency (ASLD; also known as argininosuccinic aciduria) is the second most common urea cycle disorder (UCD) and accounts for 15-20% of all disorders of ureagenesis. Individuals with ASLD can have unique clinical and physiologic characteristics as compared to other UCDs. Previous work from the members of the UCDC have shown that in spite of having fewer episodes of hyperammonemia as compared to those with proximal blockade of the urea cycle, individuals with ASLD can develop intellectual and learning disabilities. Neurocognitive deficits have been observed even in individuals without any documented hyperammonemia. Furthermore, hepatic abnormalities including hepatomegaly, hepatic injury, fibrosis and even frank cirrhosis, and vascular issues like hypertension are well known in the disorder. Previous work from the members of the UCDC has demonstrated a tissue- and molecular-specific role for ASL in the generation of NO. ASL is not only required for the synthesis of ...

Mutations and polymorphisms in the human argininosuccinate synthetase (ASS1) gene - Zurich Open Repository and ArchiveMutations and polymorphisms in the human argininosuccinate synthetase (ASS1) gene - Zurich Open Repository and Archive
Citrullinemia type I is an autosomal recessive disorder that is caused by a deficiency of the urea cycle enzyme argininosuccinate synthetase (ASS1). Deficiency of ASS1 shows various clinical manifestations encompassing severely affected patients with fatal neonatal hyperammonemia as well as asymptomatic individuals with only a biochemical phenotype. This is a comprehensive report of all 87 mutations found to date in the ASS1 gene on chromosome 9q34.1. A large proportion of the mutations (n=27) are described here for the first time. Mutations are distributed throughout exons 3 to 15, most of them being identified in exons 5, 12, 13, and 14. The mutation G390R in exon 15 is the single most common mutation in patients with the classical phenotype. Certain mutations clearly link to specific clinical courses but the clinical phenotype cannot be anticipated in all patients. This update presents a survey of the correlation between mutations in the ASS1 gene and the respective clinical courses as ...

In the linear pathway (Figure 1A), GLU is converted to acetylglutamate (Ac-GLU) by N-acetylglutamate synthase (NAGS, encoded by argA) which is inhibited by ARG through negative feedback regulation [36],[39]. Sequential catalytic reactions catalyzed by the next three enzymes, N-acetylglutamate kinase (NAGK, encoded by argB), N-acetylglutamate semialdehyde dehydrogenase (encoded by argC) and N-acetylornithine transaminase (encoded by argD), which are common in the three pathways (Figure 1), yield N-acetylornithine (Ac-ORN) [34]. The next step, which distinguishes the linear pathway from the other two pathways, is deacetylation of Ac-ORN by AOase to yield ORN [40],[41]. The next and final steps are carried out by ornithine carbamoyltransferase (OTC or OTCase, encoded by argF), argininosuccinate synthase (encoded by argG) and argininosuccinate lyase (encoded by argH), which finally yield ARG [35]. This pathway has been found in a few species such as Myxococcus xanthus [41] and E. coli [36].. In many ...

Pancreatic cancer is a leading cause of cancer-related deaths in the world with a 5-year survival rate of less than 6%. Currently, there is no successful therapeutic strategy for advanced pancreatic cancer, and new effective strategies are urgently needed. Recently, an arginine deprivation agent, arginine deiminase, was found to inhibit the growth of some tumor cells (i.e., hepatocellular carcinoma, melanoma, and lung cancer) deficient in argininosuccinate synthetase (ASS), an enzyme used to synthesize arginine. The purpose of this study was to evaluate the therapeutic efficacy of arginine deiminase in combination with gemcitabine, the first line chemotherapeutic drug for patients with pancreatic cancer, and to identify the mechanisms associated with its anticancer effects. In this study, we first analyzed the expression levels of ASS in pancreatic cancer cell lines and tumor tissues using immunohistochemistry and RT-PCR. We further tested the effects of the combination regimen of arginine deiminase

I feel like one huge swollen tonsil. Like my eustachian tubes (etruscan tubes? I cant spell yoostayshun) are on fire. The back of my throat has rabid bats roosting in it, dropping guano....burning guano, down my esophagus. And to make it even more annoying, this has been slowly slowwwwwwly coming on for two damn weeks.…

Nana Life: KIDS! ARGH!Nana Life: KIDS! ARGH!
I voted yesterday morning. Got my civic duty done. I love our little county... such sweet people, always friendly... everyone greets you with a smile and it makes every little errand or chore completely pleasant. I asked the election officials how many registered voters we have in our county... they said 14,000. So if that gives you an idea of what a small town this is... conversely... when we lived in Duval County, Florida... there are 1.1 million registered voters. This is why ... everywhere you go... you run into someone you know. If not for tourists, wed never have traffic. but we appreciate the tourists... they stimulate the economy, right ...

And by that time, Im past him and spend the rest of my ride home going back and forth in this way. Im sick of it. Maybe one day I should just come stand next to you and do the same thing, or when I forget my wallet, ask you for some change. Argh.. 3. Apple basket Pirates. Back off. Seriously. If you understand that analogy, great. If not, and you want to, just ask. 4. Two dimensional thinkers. Im used to being around people who, when faced with a problem or something they dont understand, try and figure it out on their own before asking everyone around them to do it for them. Those people are three dimensional thinkers-I would even go so far as to say they are multi-dimensional thinkers. Two dimensional thinkers make zero effort to figure something out on their own and hand it off to other people. Oh. This doesnt work. Rather than making an effort to be intelligent and solve the problem myself, Ill just call ten other people and make them do it for me because Im intellectually lazy. Im ...

So glad she does not have the flu. I know the anxiety you are having. It sounds like A has a lot of extra health issues that make having the flu a lot of extra work and even more scary. Same with M. I am constantly questioning what I am doing in order to help her stay healthy. I cant keep her in a bubble but when it is all over her school I can keep her home. Does that do any good in the long run since these outbreaks could go on and then there are different viruses anyway that can send her into CVS and then to the hospital. Sigh. Argh. I go around and around about it. ...

Have you ever had a day like this? Overslept. Didnt accomplish what I wanted. Things in the house broke. My phone kept sticking and not letting me type. ARGH! Drivers on the rainy roads drove crazy (that may have been because of my grumpy mood). I basically flailed on the edge of losing it all day long. Continue Reading…. ...
