Description:
Heavy metal recovery from biosorbents is of major importance in the assessment of competitiveness of biosorption processes. Several desorption agents (H"2SO"4, HNO"3, HCl, CH"3COOH and EDTA) were tested for the selection of the optimal elution conditions for Cr(III) recovery from Saccharomyces cerevisiae cells. Sorption time was optimised as it plays an important role in the sorption-desorption process, being shown that a 30min sorption period is the best option to ensure metal removal from solution and good recovery from biosorbent. The optimal contact time with desorption agents was also studied, as long exposures to these ones may cause cell damage, affecting biosorbent metal uptake capacity in subsequent sorption cycles. Each eluant was analysed in terms of its desorption capacity and its effect on the biomass metal uptake capacity in multiple sorption-desorption cycles. Considering the effectiveness of chromium desorption from loaded biomass, it was possible to conclude that H"2SO"4 (pH~1) was the most effective eluant tested, accomplishing the highest Cr(III) recovery from S. cerevisiae in three consecutive sorption/desorption cycles. Regarding the damage caused by acid treatment on S. cerevisiae cells, assessed by the reduction on metal uptake capacity after elution, it was possible to observe that sulphuric acid was the most harmful eluant causing long term negative effects in metal uptake. By the time the experiments were interrupted (nearly 26h of continuous cycles) biomass uptake capacity was reduced to about 77% of the value reached before acid treatment. ... Read more

Description:
Homologous recombination between dispersed repeated genetic elements is an important source of genetic variation. In this review, we discuss chromosome rearrangements that are a consequence of homologous recombination between transposable elements in the yeast Saccharomyces cerevisae. The review will be divided into five sections: (1) Introduction (mechanisms of homologous recombination involving ectopic repeats), (2) Spontaneous chromosome rearrangements in wild-type yeast cells, (3) Chromosome rearrangements induced by low DNA polymerase, mutagenic agents or mutations in genes affecting genome stability, (4) Recombination between retrotransposons as a mechanism of genome evolution, and (5) Important unanswered questions about homologous recombination between retrotransposons. This review complements several others [S. Liebman, S. Picologlou, Recombination associated with yeast retrotransposons, in: Y. Koltin, M.J. Leibowitz (Eds.), Viruses of Fungi and Simple Eukaryotes, Marcel Dekker Inc., New York, 1988, pp. 63-89; P. Lesage, A.L.

Description:
DNA lesions can stall or block high-fidelity polymerases, thus inhibiting replication. To bypass such lesions, low-fidelity translesion synthesis (TLS) polymerases can be used to insert a nucleotide across from the lesion or extend from a lesion:base mispair. When DNA repair is compromised in Saccharomyces cerevisiae, spontaneous DNA lesions can lead to a novel mutational event in which a frameshift is accompanied by one or more base pair substitutions. These ''complex frameshifts'' are dependent upon the TLS polymerase Pol@z, and provide a mutational signature for mutagenic Pol@z-dependent activity. In the current study, we have found that a specific subset of the Pol@z-dependent mutational events requires oxidative metabolism. These results suggest that translesion bypass of spontaneously oxidized DNA bases can be a significant source of mutagenesis in repair compromised cells. ... Read more

Description:
A solid phase extraction procedure using a yeast Saccharomyces cerevisiae immobilized in calcium alginate beads is proposed for the determination of Pd in road dust. Palladium was separated from the matrix elements by selective retention on the column at acidic pH (pH 1-1.5) followed by subsequent elution with 1ml of thiourea (TU) solution (0.3moll^-^1 TU in 0.25moll^-^1 HC1) and determination by graphite furnace atomic absorption spectrometry (GFAAS). The limit of detection was 7ngg^-^1. The method validation was performed by analysis of certified reference material SARM-7 (platinum ore). The concentration of Pd in road dust samples collected in Bialystok (Poland) determined by the evaluated method is in the range 114.2-215.5ngg^-^1. The analysis of data shows inhomogeneous distribution of Pd in road dust. ... Read more

Description:
In the last few years many concerns have been raised regarding the environmental safety of alkylphenol polyethoxylate surfactants (APnEOs).They are widely used in detergents, paints, herbicides and many other formulated products. It has been estimated that 60% of APnEOs end up in the aquatic environment; they are biodegradable and transformed into alkylphenols, such as nonylphenol and octylphenol that are hydrophobic and tend to accumulate. In the present study, acute and chronic aquatic toxicity and the estrogenic activity of the following eight alkylphenols were assessed: 4-nonylphenol, 4-octylphenol, 4-nonylphenol-10-ethoxylate, 4-tert-octylphenol, POE (1 to 2)-nonylphenol, POE (6)-nonylphenol, POE (3)-tert-octylphenol and POE (9 to 10)-tert-octylphenol. The toxic potential was measured on the crustaceans Daphnia magna and Ceriodaphnia dubia, while the estrogenic activity was determined by using the YES-test with the strain Saccharomyces cerevisiae RMY326. The results showed that the exposure of crustaceans to the eight xenoestrogens investigated caused both acute and chronic effects. The EC50 values found for C. dubia at 48h were compared to D. magna at 24h and, gave a first indication about the toxic activity of the compounds investigated, that is better expressed in the long-term. In fact, chronic data showed a strong increase in toxicity with EC50 values one or two orders of magnitude lower than the acute values. The results of the YES-test showed that nonylphenol, octylphenol and 4-tert-octylphenol were the most estrogenic and the bioassay was able to detect their estrogenicity at very low concentrations (ng-@mg/l). ...

Description:
Genetic integrity depends upon the precision of all pathways that manipulate DNA. DNA repair mechanisms prevent mutations and aberrant recombination events by removing DNA damage. DNA topoisomerases maintain favorable nucleic acid topology for replication, transcription, and chromosome segregation. However, topoisomerases can also become trapped on DNA at sites of damage, and thereby, might alter the efficiency of DNA repair. The activities of the three nuclear DNA topoisomerases (Top1, Top2, and Top3) in the yeast Saccharomyces cerevisiae were examined for their influence upon the nucleotide excision repair (NER) of DNA damage induced by ultraviolet (UV) irradiation. A 10-20% increase in the global genomic repair (GGR) of cyclobutane pyrimidine dimers (CPDs) was observed with impaired Top1 or Top2 function. The GGR of 6-4 photoproducts (6-4PPs) and the strand-specific removal of CPDs from the yeast RPB2 gene were unaffected by the loss of topoisomerase activity. Even though the deletion of TOP3 conferred UV sensitivity, neither the GGR nor the strand-specific repair of UV-induced DNA damage was compromised in top3@D yeast. Top1 and Top2 in DNA complexes near CPDs may inhibit GGR recognition of these lesions and produce protein-linked DNA breaks, resulting in CPD repair by an alternate pathway. While the physiological role of topoisomerase association with DNA damage has yet to be determined, these enzymes do not play a direct role in the NER pathways for removing UV-induced lesions in yeast. ...

Description:
Essential oils (EOs) extracted from medicinal plants such as Origanum compactum, Artemisia herba alba and Cinnamomum camphora are known for their beneficial effects in humans. The present study was undertaken to investigate their possible antigenotoxic effects in an eukaryotic cell system, the yeast Saccharomyces cerevisiae. The EOs alone showed some cytotoxicity and cytoplasmic petite mutations, i.e. mitochondrial damage, but they were unable to induce nuclear genetic events. In combination with exposures to nuclear mutagens such as 254-nm UVC radiation, 8-methoxypsoralen (8-MOP) plus UVA radiation and methylmethane sulfonate (MMS), treatments with these EOs produced a striking increase in the amount of cytoplasmic petite mutations but caused a significant reduction in revertants and mitotic gene convertants induced among survivors of the diploid tester strain D7. In a corresponding rho^0 strain, the level of nuclear genetic events induced by the nuclear mutagens UVC and 8-MOP plus UVA resulted in the same reduced level as the combined treatments with the EOs. This clearly suggests a close relationship between the enhancement of cytoplasmic petites (mitochondrial damage) in the presence of the EOs and the reduction of nuclear genetic events induced by UVC or 8-MOP plus UVA. After MMS plus EO treatment, induction of these latter events was comparable at least per surviving fraction in wildtype and rho^0 cells, and apparently less dependent on cytoplasmic petite induction. Combined treatments with MMS and EOs clearly triggered switching towards late apoptosis/necrosis indicating an involvement of this phenomenon in EO-induced cell killing and concomitant decreases in nuclear genetic events. After UVC and 8-MOP plus UVA plus EO treatments, little apoptosis and necrosis were observed. The antigenotoxic effects of the EOs appeared to be predominantly linked to the induction of mitochondrial dysfunction. ... Read more

Description:
Saccharomyces cerevisiae DNA polymerase delta (Pol@d) is a heterotrimeric enzyme consisting of Pol3 (the catalytic subunit), Pol31 and Pol32. New pol31 alleles were constructed by introducing mutations into conserved amino acid residues in all 10 identified regions of Pol31. Six novel temperature-sensitive (ts) or cold-sensitive (cs) alleles, carrying mutations in regions III, IV, VII, VIII or IX, conferred a range of defects in the response to replication stress or DNA damage. Deletion of SGS1, RAD52, SRS2, MRC1 or RAD24 had a deleterious effect only in combination with those pol31 alleles that had a phenotype as single mutants, suggesting a requirement for recombination and checkpoint functions in processing the DNA lesions or structures that form as a consequence of replication with a defective Pol@d. In contrast, deletion of POL32 negatively affected the growth of almost all pol31 mutants, suggesting an important role for all conserved amino acids of Pol31 in maintaining the integrity of Pol@d complex structurally, at least in the absence of the third subunit. Surprisingly, deletions of RAD18 and MGS1 aggravated the temperature sensitivity conferred by most ts or cs alleles and specifically suppressed the hys2-1 and hys2-1-like mutations of POL31. Deletion of RAD5 or MMS2 had an effect on pol31 ts/cs mutants similar to that of RAD18, whereas deletion of RAD30 or REV3 had no effect. We propose that Rad18/Rad5/Mms2 and Mgs1 are required to promote replication when forks are destabilized or stalled due to defects in Pol@d. These data are consistent with the biochemical activity of the human Mgs1 orthologue, which binds and stimulates Pol@din vitro. We also demonstrate that Mgs1 interacts physically with Pol31 in vivo. Moreover, regions I and VII of Pol31, which are specifically sensitive to high levels of Mgs1 and PCNA, could be sites of interaction. ... Read more

Description:
Previous analyses of both Thermus aquaticus MutS homodimer and Saccharomyces cerevisiae Msh2-Msh6 heterodimer have revealed that the subunits in these protein complexes bind and hydrolyze ATP asymmetrically, emulating their asymmetric DNA binding properties. In the MutS homodimer, one subunit (S"1) binds ATP with high affinity and hydrolyzes it rapidly, while the other subunit (S"2) binds ATP with lower affinity and hydrolyzes it at an apparently slower rate. Interaction of MutS with mismatched DNA results in suppression of ATP hydrolysis at S"1-but which of these subunits, S"1 or S"2, makes specific contact with the mismatch (e.g., base stacking by a conserved phenylalanine residue) remains unknown. In order to answer this question and to clarify the links between the DNA binding and ATPase activities of each subunit in the dimer, we made mutations in the ATPase sites of Msh2 and Msh6 and assessed their impact on the activity of the Msh2-Msh6 heterodimer (in Msh2-Msh6, only Msh6 makes base specific contact with the mismatch). The key findings are: (a) Msh6 hydrolyzes ATP rapidly, and thus resembles the S"1 subunit of the MutS homodimer, (b) Msh2 hydrolyzes ATP at a slower rate, and thus resembles the S"2 subunit of MutS, (c) though itself an apparently weak ATPase, Msh2 has a strong influence on the ATPase activity of Msh6, (d) Msh6 binding to mismatched DNA results in suppression of rapid ATP hydrolysis, revealing a ''cis'' linkage between its mismatch recognition and ATPase activities, (e) the resultant Msh2-Msh6 complex, with both subunits in the ATP-bound state, exhibits altered interactions with the mismatch. ...

Description:
The Mre11-Rad50-Xrs2 complex in Saccharomyces cerevisiae has roles in the intra-S checkpoint, homologous recombination, non-homologous end joining, meiotic recombination, telomere maintenance and the suppression of gross chromosomal rearrangements (GCRs). The discovery of mutations in the genes encoding the human homologues of two MRX subunits that underlie the chromosome fragility syndromes, Ataxia telangiectasia-like disorder and Nijmegen breakage syndrome suggest that the MRX complex also functions in suppression of GCRs in human cells. Previously, we demonstrated that the deletion mutations in each of the MRX genes increased the rate of GCRs up to 1000-fold compared to wild-type rates. However, it has not been clear which molecular function of the MRX complex is important for suppression of GCRs. Here, we present evidence that at least three different activities of the MRX complex are important for suppression of GCRs. These include the nuclease activity of Mre11, an activity related to MRX complex formation and another activity that has a close link with the telomere maintenance function of the MRX complex. An activity related to MRX complex formation is especially important for the suppression of translocation type of GCRs. However, the non-homologous end joining function of MRX complex does not appear to participate in the suppression of GCRs. ... Read more

Product Description
Webster's bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people. They do so from a linguistic point of view, and in the case of this book, the focus is on "Saccharomyces," including when used in literature (e.g. all authors that might have Saccharomyces in their name). As such, this book represents the largest compilation of timeline events associated with Saccharomyces when it is used in proper noun form. Webster's timelines cover bibliographic citations, patented inventions, as well as non-conventional and alternative meanings which capture ambiguities in usage. These furthermore cover all parts of speech (possessive, institutional usage, geographic usage) and contexts, including pop culture, the arts, social sciences (linguistics, history, geography, economics, sociology, political science), business, computer science, literature, law, medicine, psychology, mathematics, chemistry, physics, biology and other physical sciences. This "data dump" results in a comprehensive set of entries for a bibliographic and/or event-based timeline on the proper name Saccharomyces, since editorial decisions to include or exclude events is purely a linguistic process. The resulting entries are used under license or with permission, used under "fair use" conditions, used in agreement with the original authors, or are in the public domain. ... Read more

Description:
Aneuploidy is the most frequent aberration observed in tumor cells, and underlies many debilitating and cancer-prone congenital disorders. Aneuploidy most often arises as a consequence of chromosomal non-disjunction, however, little is known about the genetic and epigenetic factors that affect the chromosomal segregation process. As many cancer-prone syndromes are associated with defects in DNA repair pathways we decided to investigate the relationship between DNA repair in mutation avoidance pathways, namely base and nucleotide excision, and mismatch repair (MMR), and aneuploidy in the yeast Saccharomyces cerevisiae. Isogenic haploid and diploid DNA repair deficient yeast strains were constructed, and spontaneous levels of intra- and inter-chromosomal recombination, forward mutation, chromosome gain, and loss were measured. We show that the nucleotide excision repair (NER) pathway is required for accurate chromosomal disjunction. In the absence of Rad1, Rad2, or Rad4, spontaneous levels of chromosome XV gain were significantly elevated in both haploid and diploid mutant strains. Thus, chromosome gain may be an additional cancer predisposing event in NER deficient patients. ... Read more
