Two previously reported non‐synonymous coding single nucleotide polymorphisms (SNPs) of bovine stearoyl‐CoA desaturase (delta‐9‐desaturase) (SCD) (c.878C>T) and fatty acid synthase (FASN) (g:17924A>G) were assessed for their associations with 72 individual and 12 groups of fatty acids in brisket adipose tissue of 223 Canadian commercial cross‐bred beef steers. It was found that the ‘CC’ genotype of the SCD SNP was significantly associated with lower concentrations of saturated fatty acids (SFA) including 10:0, 14:0 and 20:0, higher concentrations of monounsaturated fatty acids including 9c‐14:1, 12c‐16:1 and 13c‐18:1, higher concentrations of polyunsaturated fatty acids (PUFA) including 9c,15c‐18:2, 10c,12c‐18:2, 11c,13t‐18:2 and 12c,14t‐18:2, but lower concentrations of other PUFA of 9c,13t/8t,12c and 20:2n‐6 (P < 0.05). The ‘AA’ genotype of the FASN SNP was significantly associated with higher concentrations of SFAs of 10:0, 12:0, 13:0, 14:0 and 15:0, lower concentrations of unsaturated fatty acids of 9c‐18:1 and 20:3n‐6, and higher concentrations of unsaturated fatty acids of 9c‐14:1 and 12c‐16:1 (P < 0.05). Significant epistatic effects between the SCD and FASN SNP genotypes were also found for several fatty acids including 10:0, 23:0, 6t/7t/8t‐18:1, 12t‐18:1, 13t/14t‐18:1, 16t‐18:1, total trans18:1 and 9c,13t/8t,12c‐18:2 (P < 0.05). These results further suggest that SCD and FASN are strong candidate genes influencing fatty acid composition in beef cattle.  相似文献

Objective: To survey the present state of undergraduate teaching in the domain of gerodontology in Germany, Switzerland and Austria. Study participants: All universities of Austria (A), Germany (D) and Switzerland (CH). Protocol: A questionnaire on undergraduate teaching in gerodontology was mailed to all Deans (A: n = 3; CH: n = 4; D: n = 31) and all independent departments except paediatric dentistry and orthodontics (A: n = 11; CH: n = 15; D: n = 111). Results: The questionnaires were completed and returned by 29 Deans (A: n = 2; CH: n = 4; D: n = 23) and 102 departments (A: n = 7; CH: n = 8; D: n = 87). In Austria, gerodontology is a very small component of the dental curriculum and the Deans did not want this to be increased. Most German universities claimed to teach some aspects of gerodontology to undergraduate students and 87.4% of the Deans voted for separate lectures in gerodontology. In Switzerland, gerodontology seems well established. The results of questionnaires from the independent departments revealed that in all three countries lectures were more prevalent (A: n = 0; CH: n = 4; D: n = 6) than practical training in nursing homes (A: n = 0; CH: n = 3; D: n = 6). Conclusion: Considering the demographical shift which is leading to an increasing proportion of elderly in the population, the weighting of gerodontology in the undergraduate dental curriculum should be considered for revision in Austria and Germany.  相似文献

RpoN is a σ54 factor regulating essential virulence gene expression in several plant pathogenic bacteria, including Pseudomonas syringae and Pectobacterium carotovorum. In this study, we found that mutation of rpoN in the fire blight pathogen Erwinia amylovora caused a nonpathogenic phenotype. The E. amylovora rpoN Tn5 transposon mutant rpoN1250::Tn5 did not cause fire blight disease symptoms on shoots of mature apple trees. In detached immature apple fruits, the rpoN1250::Tn5 mutant failed to cause fire blight disease symptoms and grew to population levels 12 orders of magnitude lower than the wild‐type. In addition, the rpoN1250::Tn5 mutant failed to elicit a hypersensitive response when infiltrated into nonhost tobacco plant leaves, and rpoN1250::Tn5 cells failed to express HrpN protein when grown in hrp (hypersensitive response and pathogenicity)‐inducing liquid medium. A plasmid‐borne copy of the wild‐type rpoN gene complemented all the rpoN1250::Tn5 mutant phenotypes tested. The rpoN1250::Tn5 mutant was prototrophic on minimal solid and liquid media, indicating that the rpoN1250::Tn5 nonpathogenic phenotype was not caused by a defect in basic metabolism or growth. This study provides clear genetic evidence that rpoN is an essential virulence gene of E. amylovora, suggesting that rpoN has the same function in E. amylovora as in P. syringae and Pe. carotovorum.  相似文献

The role of p300 in DNA damage response is unclear. To understand how ATM-dependent phosphorylation of p300 affects its function in response to DNA damage, we present evidence that S106 of p300, which is phosphorylated by ATM, regulates stability of NBS1 and recruitment into damaged DNA, possibly leading to regulation of DNA repair. Non-phosphorylatable p300 (S106A) destabilized NBS1 and decreased NBS1–p300 interaction. The recruitment of NBS1 into damaged DNA was impaired in the presence of S106A. Also, a dominant negative p300 lacking enzymatic activity induced destabilization of NBS1, suggesting that its acetyltransferase is required for NBS1 stability. These results indicate that phosphorylation of p300 can regulate NBS1-mediated DNA damage response, and that these events occur in an acetylation-dependent manner.

Sinorhizobium meliloti infects leguminous plants resulting in a nitrogen-fixing symbiosis. Free living cells accumulate poly(3-hydroxybutyrate) (PHB) as carbon and energy source under imbalanced growth conditions. The cphA1 7120 gene encoding a cyanophycin (CGP) synthetase of Anabaena sp. PCC7120 in plasmids pVLT31::cphA1 7120 and pBBR1MCS-3::cphA1 7120 was expressed in the wild-type S. meliloti 1021 and in a phbC-negative mutant generated in this study. Expression of cphA1 7120 and accumulation of CGP in cells were studied in various media. Yeast mannitol broth (YMB) and pBBR1MCS-3::cphA1 7120 yielded the highest CGP contents in both S. meliloti 1021 strains. Supplying the YMB medium with isopropyl-β-D-thiogalactopyranoside, aspartic acid, and arginine enhanced CGP contents about 2.5- and 2.8-fold in S. meliloti 1021 (pBBR1MCS-3::cphA1 7120) and S. meliloti 1021 phbCΩKm (pBBR1MCS-3::cphA1 7120), respectively. Varying the nitrogen-to-carbon ratio in the medium enhanced the CGP content further to 43.8% (w/w) of cell dry weight (CDW) in recombinant cells of S. meliloti 1021 phbCΩKm (pBBR1MCS-3::cphA1 7120). Cells of S. meliloti 1021 (pBBR1MCS-3::cphA1 7120) accumulated CGP up to 39.6% in addition to 12.1% PHB (w/w, of CDW). CGP from the S. meliloti strains consisted of equimolar amounts of aspartic acid and arginine and contained no other amino acids even if the medium was supplemented with glutamic acid, citrulline, ornithine, or lysine. CGP isolated from cells of S. meliloti 1021 (pBBR1MCS-3::cphA1 7120) and S. meliloti 1021 phbCΩKm (pBBR1MCS-3::cphA1 7120) exhibited average molecular weights between 20 and 25 kDa, whereas CGP isolated from Escherichia coli S17-1 (pBBR1MCS-3::cphA1 7120) exhibited average molecular weight between 22 and 30 kDa. Co-expression of cyanophycinase from Anabaena sp. PCC7120 encoded by cphB1 7120 in cphA1 7120-positive E. coli S17-1, S. meliloti 1021, and its phbC-negative mutant gave cyanophycinase activities in crude extracts, and no CGP granules occurred. A higher PHB content in S. meliloti 1021 (pBBR1MCS-3::cphB1 7120::cphA1 7120) in comparison to the control indicated that the cells used CGP degradation product (β-aspartate-arginine dipeptide) to fuel PHB biosynthesis.  相似文献

Summary The products of 11 switching (swi) genes are required for efficient mating-type (MT) switching in homothallic (h 90) strains of Schizosaccharomyces pombe. The MT region of h 90 comprises three cassette genes: the expression site mat1: 1 and two silent loci, mat2: 2 and mat3: 3. Besides reducing MT switching, the swi6 mutation leads to deletions in the MT region caused by intrachromosomal cross-overs between two paired cassettes. These deletions only arise if DNA double-strand breaks are present at mat1: 1, which initiate MT switching. Furthermore, swi6 allows meiotic recombination in the K region, a region of 16 kb between mat2: 2 and mat3: 3; in wild-type strains no recombination occurs in K. swi6 also allows the simultaneous expression of two different cassettes in the same haploid cell. Thus swi6 may have an influence on the general chromatin structure in the MT region.  相似文献

Dietary restriction (DR) is the only environmental intervention known to extend adult lifespan in a wide variety of animal models. However, the genetic and cellular events that mediate the anti-aging programs induced by DR remain elusive. Here, we used the nematode Caenorhabditis elegans to provide the first in vivo evidence that a thioredoxin (TRX-1) regulates adult lifespan extension induced by DR. We found that deletion of the gene trx-1 completely suppressed the lifespan extension caused by mutation of eat-2, a genetic surrogate of DR in the worm. However, trx-1 deletion only partially suppressed the long lifespan caused by mutation of the insulin-like receptor gene daf-2 or by mutation of the sensory cilia gene osm-5. A trx-1::GFP translational fusion expressed from its own promoter in ASJ neurons (Ptrx-1::trx-1::GFP) rescued the trx-1 deletion-mediated suppression of the lifespan extension caused by mutation of eat-2. This rescue was not observed when trx-1::GFP was expressed from the ges-1 promoter in the intestine. In addition, overexpression of Ptrx-1::trx-1::GFP extended lifespan in wild type, but not in eat-2 mutants. trx-1 deletion almost completely suppressed the lifespan extension induced by dietary deprivation (DD), a non-genetic, nutrient-based model of DR in the worm. Moreover, DD upregulated the expression of a trx-1 promoter-driven GFP reporter gene (Ptrx-1::GFP) in ASJ neurons of aging adults, but not that of control Pgpa-9::GFP (which is also expressed in ASJ neurons). We propose that DR activates TRX-1 in ASJ neurons during aging, which in turn triggers TRX-1-dependent mechanisms to extend adult lifespan in the worm.  相似文献
