In response to replication stress, a phospho-signaling cascade is activated and required for coordination of DNA repair and replication of damaged templates (intra-S phase checkpoint). How phospho-signaling coordinates the DNA replication stress response is largely unknown. We employed state-of-the-art liquid chromatography tandem mass spectrometry (LC-MS/MS) approaches to generate high-coverage and quantitative proteomic and phospho-proteomic profiles during replication stress in yeast, induced by continuous exposure to the DNA alkylating agent methyl methanesulfonate (MMS). We identified 32,057 unique peptides representing the products of 4,296 genes, and 22,061 unique phosphopeptides representing the products of 3,183 genes. 542 phosphopeptides (mapping to 339 genes) demonstrated an abundance change of ≥ 2-fold in response to MMS. The screen enabled detection of nearly all of the proteins known to be involved in the DNA damage response, as well as many novel MMS-induced phosphorylations. We ...

One of the most crucial tasks for a cell to ensure its long term survival is preserving the integrity of its genetic heritage via maintenance of DNA structure and sequence. While the DNA damage response in the yeast Saccharomyces cerevisiae, a model eukaryotic organism, has been extensively studied, much remains to be elucidated about how the organism senses and responds to different types and doses of DNA damage. We have measured the global transcriptional response of S. cerevisiae to multiple doses of two representative DNA damaging agents, methyl methanesulfonate (MMS) and gamma radiation. Hierarchical clustering of genes with a statistically significant change in transcription illustrated the differences in the cellular responses to MMS and gamma radiation. Overall, MMS produced a larger transcriptional response than gamma radiation, and many of the genes modulated in response to MMS are involved in protein and translational regulation. Several clusters of coregulated genes whose responses varied

Alkylating agents induce cytotoxic DNA base-adducts. In this thesis I provide evidence to suggest that Saccharomyces cerevisiae Tpa1 protein is involved in DNA alkylation repair. Little is known about Tpa1 as a repair protein beyond the initial observation from a high throughput analysis indicating that deletion of TPA1 causes methyl methane sulfonate (MMS) sensitivity in Saccharomyces cerevisiae. Using purified Tpa1, I demonstrate that wild type Tpa1 repairs both single and double-stranded methylated DNA and mutation of the amino acid residues involved in cofactor binding abolishes Tpa1 DNA repair activity. In this thesis I also investigate genetic interaction of Tpa1. I also demonstrate that Tpa1 could complement alkB function and rescue the MMS sensitivity of alkB deficient E.coli strain, HK82. Experimental data proves that deletion of TPA1 along with base excision repair (BER) pathway DNA glycosylase MAG1 renders the tpa1 ∆ mag1 ∆ double mutant highly susceptible to methylation-induced ...

MMS induces diverse rII mutations from a wild-type background in bacteriophage T4. About 56% are base pair substitutions, about 30% are frameshift mutations, and the remainder is a miscellaneous set of rapidly reverting or leaky mutants of unknown composition; but deletions were not detected. MMS-induced forward mutation is sharply reduced by the mutations px and y, which also reduce ultraviolet, photodynamic and γ-ray mutagenesis and increase killing by all of these agents. Thus, many of the mutations arise via the T4 WXY system. The induction of G:C → A:T transitions was detected even in a px or y background using sensitive reversion tests, and the few forward rII mutations that were induced from this background also behaved like transition mutations. Thus, some MMS-induced mutations arise independently of the WXY system, perhaps as a result of the (rather weak) ability of MMS to alkylate the O6 position of guanine.. ...

Pancreatic β-cells are able to repair themselves after some sublethal injuries in vitro. However, little is known of the nature of the repair mechanisms active in these cells. This study examined the expression of growth arrest and DNA damage-inducible genes gadd 153 and gadd 45 in pancreatic rat islets and in the clonal insulin secretory HIT-T15 cells. Rat pancreatic islets were exposed in vitro to the alkylating agents streptozocin or methyl methanesulfonate, or to the cytokine recombinant interleukin-1 β. Islet exposure to STZ or MMS reduced insulin release by 40-50% over the next 4 h, whereas exposure to rIL-1 β induced a 60% increase in insulin release over the same period. Both gadd 153 and gadd 45 mRNA were detectable in rat islets, and their levels were increased twofold after STZ exposure, whereas MMS induced a fivefold increase in gadd 153 and a twofold increase in gadd 45 mRNA. Islet exposure to rIL-1β did not affect the expression of gadd 153 or gadd 45. HIT cells exposed to STZ ...

The reason why lots of herpes cases remain unattended is that some people do not have any noticeable indications. About 80 % of people carrying the virus are unaware of it resulting in the high rate of annual transmission. In his book Rare Earths Forbidden Cures, Dr. Your body has a lack of oxygen. A short flair last year responded to 3 days of mms treatment and all has been well for over one year. It is important to consume healthy meals to enhance the body immune system to help in fighting the virus. When advising a mineral cleansing program, a specialist might suggest both partners partake in the program due to the fact that there are high chances both partners are infected despite signs and symptoms visibility.. Research shows that 200 mg daily is efficient. But if theres one thing we all know about the U.S. Admittedly, however, there is a solution.

In a gene trap screen we recovered a mouse mutant line in which an insertion generated a null allele of the Brd4 gene. Brd4 belongs to the Fsh/Brd family, a group of structurally related proteins characterized by the association of two bromodomains and one extraterminal domain. Members of this family include Brd2/Ring3/Fsrg1 in mammals, fs(1)h in Drosophila, and Bdf1 in Saccharomyces cerevisiae. Brd4 heterozygotes display pre- and postnatal growth defects associated with a reduced proliferation rate. These mice also exhibit a variety of anatomical abnormalities: head malformations, absence of subcutaneous fat, cataracts, and abnormal liver cells. In primary cell cultures, heterozygous cells also display reduced proliferation rates and moderate sensitivity to methyl methanesulfonate. Embryos nullizygous for Brd4 die shortly after implantation and are compromised in their ability to maintain an inner cell mass in vitro, suggesting a role in fundamental cellular processes. Finally, sequence ...

Ayurveda, the traditional Indian system of medicine has given great emphasis to the promotion of health. Rasayana is one of the eight branches of Ayurveda which refers to rejuvenant therapy. It has been reported that rasayanas have immuno-modulatory, antioxidant and antitumor functions, however, the genotoxic potential and modulation of DNA repair of many rasayanas have not been evaluated. The present study assessed the role of Brahmarasayana (BR) on Ethyl methanesulfonate (EMS)-and Methyl methanesulfonate (MMS)-induced genotoxicity and DNA repair in in vivo mouse test system. The mice were orally fed with BR (5 g or 8 mg / day) for two months and 24 h later EMS or MMS was given intraperitoneally. The genotoxicity was analyzed by chromosomal aberrations, sperm count, and sperm abnormalities. The results have revealed that BR did not induce significant chromosomal aberrations when compared to that of the control animals (p |0.05).

TY - JOUR. T1 - Analysis of heat-labile sites generated by reactions of depleted uranium and ascorbate in plasmid DNA. AU - Wilson, Janice. AU - Young, Ashley. AU - Civitello, Edgar R. AU - Stearns, Diane M. PY - 2014. Y1 - 2014. N2 - The goal of this study was to characterize how depleted uranium (DU) causes DNA damage. Procedures were developed to assess the ability of organic and inorganic DNA adducts to convert to single-strand breaks (SSB) in pBR322 plasmid DNA in the presence of heat or piperidine. DNA adducts formed by methyl methanesulfonate, cisplatin, and chromic chloride were compared with those formed by reaction of uranyl acetate and ascorbate. Uranyl ion in the presence of ascorbate produced U-DNA adducts that converted to SSB on heating. Piperidine, which acted on DNA methylated by methyl methanesulfonate to convert methyl-DNA adducts to SSB, served in the opposite fashion as U-DNA adducts by decreasing the level of SSB. The observation that piperidine also decreased the gel shift ...

Yes, I have tried MMS. I read all about it first, mainly from Jim Humblew website, whose website seems to be the origin & creation of MMS. I thought Id give it a go....I agreed to do it with someone who was terminally ill, as a way of giving them moral & encouragement, so that they didnt feel they were going it alone, as it were. So we both started a course of MMS together...I got up to 7 drops & had two bouts of serious nausea, that I can only describe as psychological/mental nausea, it lasted most of the day, & was most unpleasant. I dropped down a drop, of MMS & continued, though did not proceed further than 7 drops as the nausea was putting me off big time...this was an apparent indication it was working. I cant realy say I gave it a fir trial though. Also the friend who tried it, was also having chemotherapy aswell, so it wasnt really a clear indication of its failure or success. She made great progress in her healing, though sadly not a full recovery. The chemo led to further ...

The tumour suppressor protein p53 is a critical protein in the DNA damage checkpoint pathway. It acts as a transcription factor that is involved in initiating the apoptotic pathway; disruption of this pathway can lead to various forms of cancer. Due to its importance in cancer prevention, p53 has been extensively studied, though only a small fraction of these studies have been in non-mammalian models. Some previous studies of p53 expression and regulation in lower vertebrate species have shown potential differences in its control, in comparison to the better characterized mammalian pathways. These differences emphasize the need to further investigate its mechanism of action in lower vertebrate models. To evaluate its biomarker potential for aquatic toxicology studies, two rainbow trout cell lines (RTbrain-W1 and RTgill-W1) were used in dose response experiments using DNA damage checkpoint inducing agents: bleomycin, hydroxyurea, and methyl methanesulfonate. For our studies, a rainbow trout ...

Why should yeast have a specific IMP 5-nucleotidase? One possibility is that Isn1p could be involved in scavenging IMP toxic derivatives or analogs. Our attempts to document such an effect were unsuccessful : the isn1 knock-out mutant, grown in the presence of several purine analogs (8-azaadenine, 6-chloropurine, 8-azaguanine, 6-mercaptopurine, 2,6-diaminopurine...), did not show any growth alteration compared to the isogenic wild-type strain (data not shown). Alternatively, Isn1p could play some role in DNA repair. Indeed, transcriptome analysis revealed that ISN1 transcription increased three folds when cells were treated with methyl methanesulfonate, a DNA damaging agent [17], and furthermore, Isn1p co-purified with Mlh1p [18], a protein involved in mismatch repair [19]. It is therefore tempting to propose that Isn1p could for example be involved in removing dIMP residues resulting from deamination of dAMP. However, while the mutagenic effect of dIMP has been documented [20], this ...

The overproduction of the ClpYQ protease leads to the suppression of two lon mutant phenotypes, MMS sensitivity and capsule overproduction, dependent on two different Lon substrates, SulA and RcsA. Furthermore, MMS resistance correlates with a failure to accumulate SulA, consistent with the rapid degradation of SulA when ClpYQ is overproduced. Both subunits of the ClpYQ protease are necessary for SulA degradation. In vitro, both subunits are required for the ATP-dependent degradation of casein (25). Khattar independently identified ClpYQ in a search for multicopy suppressors of the sensitivity of lon mutants to the SOS inducer nitrofurantoin (26).. The overlap in substrate specificity between Lon and ClpYQ is observed not only for overproduced ClpYQ but also for the protease produced at normal physiological levels. SulA is more stable in lon clpQand lon clpY double mutants than in the lonsingle mutant. At elevated temperatures, this additional stability correlates with increased MMS sensitivity. ...

Here, we demonstrate that OTUD4 may serve as a master regulator of alkylation damage resistance through stabilization of the human AlkB homologues. A number of distinct lines of evidence support this role for OTUD4. First, OTUD4 interacts specifically with ALKBH2 and ALKBH3 and encodes a K48‐specific DUB (Fig 1). Consistently, ALKBH3 is subjected to K48‐linked ubiquitination and proteasomal degradation (Fig 2A-D). OTUD4 antagonizes ALKBH3 ubiquitination and stabilizes both ALKBH2 and ALKBH3 in vivo (Fig 2E-H). ALKBH3 protein levels do not correlate well with ALKBH3 mRNA levels in various tumor cell lines but do correlate with OTUD4 levels (Supplementary Fig S2). Finally, overexpression of ALKBH3 in PC‐3 cells, which depend primarily on ALKBH3 instead of ALKBH2 for alkylation damage resistance, is sufficient to rescue alkylation damage sensitivity upon loss of OTUD4 (Fig 7G).. What is most striking is that we find OTUD4 catalytic activity to be apparently dispensable for its stabilization ...

Polymerase α is an essential enzyme mainly mediating Okazaki fragment synthesis during lagging strand replication. A specific point mutation in Schizosaccharomyces pombe polymerase α named swi7-1, abolishes imprinting required for mating-type switching. Here we investigate whether this mutation confers any genome-wide defects. We show that the swi7-1 mutation renders cells hypersensitive to the DNA damaging agents methyl methansulfonate (MMS), hydroxyurea (HU) and UV and incapacitates activation of the intra-S checkpoint in response to DNA damage. In addition we show that, in the swi7-1 background, cells are characterized by an elevated level of repair foci and recombination, indicative of increased genetic instability. Furthermore, we detect novel Swi1-, -Swi3- and Pol α- dependent alkylation damage repair intermediates with mobility on 2D-gel that suggests presence of single-stranded regions. Genetic interaction studies showed that the flap endonuclease Fen1 works in the same pathway as Pol ...

The ubiquitin E1, E2, and E3 ligase enzymes are the enzymatic core of the ubiquitination pathway. The E2-E3 complex interacts with the substrate, catalyzing ubiquitin addition to the substrate. Thus, the expression, activity, localization, and selectivity of ubiquitin E2s and E3s are important parameters that can serve to regulate ubiquitination. The E2-E3 combination used in the ubiquitination reaction can also influence the fate of the substrate through determining the extent and nature of ubiquitin addition. The majority of substrates observed to date are modified by the attachment of a Lys-48-linked ubiquitin chain, which targets the substrate for degradation by the 26S proteasome. Substrates modified with other types of polyubiquitin chains linked via ubiquitin Lys-6, -11, -29, and -63, or modified with a single ubiquitin, face different or unknown fates. For example, the heterodimeric E2 UBC13/methyl methane sulfonate sensitivity 2 functions with the RING E3 TNF receptor-associated factor ...

The Toxic Substances Control Act mandates the testing of industrial chemicals for which insufficient evidence of safety exists. One of the more critical areas in chemical carcinogenesis testing is a dependable approach to confirmatory tests (tier 2) of identified positives at a screening level (tier 1). The present work was undertaken as part of a systematic evaluation of a series of short-term in vitro and in vivo tests which possess properties thought desirable for tier 2 testing. Experiments were designed to determine whether the mouse skin responds to initiating doses of carcinogens selected from the major carcinogen classes administered by four routes, oral, IP, Sub Q and topical. Experiments to date include testing of diethylnitrosamine, urethane, benzene, benzo(a)pyrene, DMBA, aflatoxin B1, methylmethane sulfonate, azobenzene, FANFT and lead acetate. Two weeks following application of the initiating doses of each carcinogen a 20 week promotion schedule involving the application of lug of ...

The instructions given here are for the original, and what I like to call, Classic Protocol 1000. If you do further research you will find that we and many other people have tried various versions of Protocol 1000 over the years. While most all of the slight variations of Protocol 1000 have been successful, according to reports we have received from around the world the success has never been as good as the original protocol of mixing the dose fresh every hour. Protocol 1000 is taking a maximum of 3 drops of activated MMS (MMS1) in 4 ounces/120 ml of water once each hour, for eight consecutive hours, every day, for three weeks or until well. Do not start out at 3 drops an hour. Try to build up to 3 drops slowly. If your body does not tolerate an increase of drops, stick with what works best for you. Your health may be recovered taking less than 3 drops in each dose. Some people have recovered their health taking 1 or 2 drops per hour, and in rare cases even less. It is best to start out slow and ...

DNA dsb represent a severe type of damage that can be provoked in cell nuclei by exposure to ionizing radiation and also to chemicals such as etoposide, methylmethane sulphonate and bleomycin. Both radiation and chemical agents induce a variety of other DNA lesions such as base and sugar modifications, and single-strand breaks mostly mediated by the formation of highly reactive oxygen radicals (Iliakis, 1991). Although dsb are perhaps the lesions that most strongly threaten cell survival, it is likely that damaged cells seek to repair all DNA lesions produced by the oxygen radicals, thus activating several DNA repair pathways (Wood, 1996). Therefore, by using these DNA damaging agents, it might be difficult to analyze exclusively the repair of DNA dsb. On the other hand, it is desirable to have an in vitro system to study the repair of dsb produced in an environment as close as possible to the cell nucleus.. We used prokaryotic restriction enzymes (REs) in order to introduce solely dsb in the ...
