Expression data from dietary restricted budding yeast

ABSTRACT: Dietary restriction (also known as caloric/calorie restriction; CR) extends the lifespan of species from all three eukaryotic kingdoms. The restriction of the diet interferes directly with the aging process by triggering a tightly controlled genetic program where specific sets of genes are either upregulated downreguled. We used microarray-technology to detail the global program of gene expression underlying the anti-aging effect of dietary restriction and identified distinct classes of up- and down-regulated genes. In order to apply dietary restriction in budding yeast we cultured cells on a reduced glucose medium (0.5% vs. 2.0%), which is known as moderate DR regimen. We then compared mRNA expression of yeast cells cultured under dietary restricted (0.5% glucose) and ad libitum (2.0% glucose) conditions.

Time-course expression data during assurance of the chronological longevity by caloric restriction in budding yeast

Project description:Caloric restriction (CR) is the only non-genetic intervention to retard aging and increase longevity in a variety of species. It is important to understand the fundamental mechanism by which CR extends lifespan that remains elusive. Owing to well-established genomic tools and convenience of culture system, we used a single cell organism, Saccharomyces cerevisiae, to clarify the mechanisms of CR. In order to identify genes responsible for CR-mediated longevity, we performed microarray experiments across the longevity assurance time-points. Since the CR-treated cells obtained the longevity potential around 12 hours after inoculation and the strength of potential gradually increased up to 48 hours, we concluded that the changes across these time-points must be a critical need for assurance of longevity by CR. For preparation of total RNA, yeast cells under control (2% glucose) and CR (0.5% glucose) conditions were harvested at 12h, 18h, 24h and 48h after inoculation. After total RNA extraction, we performed Affymetrix Yeast GeneChip 2.0 array for biological triplicate repeats according to the manufacturer's instructions.

Nuclear tRNA sequestering slows aging by a mechanism similar to dietary restriction

Project description:Dietary restriction (DR) is the best-characterized intervention for slowing aging, and reduced signaling through the target of rapamycin (TOR) kinase is believed to be one of the key mechanisms by which DR extends life span in organisms from yeast to mammals. Here we describe a role for nuclear sequestration of tRNA in yeast replicative life span (RLS) extension from DR. DR causes the nuclear tRNA exporter Los1 to become depleted from the nucleus by a mechanism that requires the DNA damage response factor Rad53, and deletion of LOS1 or overexpression of RAD53 is sufficient to extend RLS. We further report that activation of the nitrogen responsive transcription factor Gln3 is the primary mechanism by which DR extends RLS. Gln3 is activated by both branches of the DR response and is required for life span extension. Overexpression of Gln3 extends RLS by approximately 50%. In order to identify potential factors acting to modulate longevity downstream of Los1, we used microarray analysis to compare the gene expression profiles of wild type and LOS1 knockout cells under non-restricted conditions cultured overnight prior to RNA isolation.

Transcriptome profiling reveals a novel role for Trichostatin A in antagonizing histone chaperone Chz1 mediated telomere anti-silencing.

Project description:The histone chaperones play an important role in chromatin assembly and disassembly during replication and transcription. We assessed the global roles of histone chaperones in Saccharomyces cerevisiae. Microarray transcriptional analyses indicate that histone chaperones have their own specific target genes, and various histone chaperones have partially overlapping functions during transcriptional regulation. Histone deacetylase inhibitor TSA and histone chaperones Asf1, Vps75 and Rtt106 can function in parallel pathways to regulate transcription. Moreover, TSA can specifically antagonize histone chaperone Chz1-mediated telomere anti-silencing. This study demonstrates that a mutual cross-talk mechanism exists between histone chaperones and histone deacetylation in transcriptional regulation. All yeast strains used in this study are listed in the paper (Table S1). CHZ1, NAP1, ASF1, VPS75 and RTT106 genes were deleted individually by homologous recombination in BY4742 (WT) by using a previously described in (Wan, Y. et al. MCB, 2009) PCR-based procedure. The strains were cultured at 30°C in YPD (1% yeast extract, 2% peptone, 2% glucose) media. For TSA treatments, WT and deletion mutants were grown to mid-log phase (OD600=0.5), TSA (Sigma-Aldrich) was then added to the yeast cultures at a final concentration of 10 ?M and cells were cultured for additional hour.Total RNA was isolated by hot acid phenol extraction protocol as previously described in Wan, Y. et al. MCB, 2009. Microarray labeling and hybridization reactions were performed as previously described in Wan, Y. et al. MCB, 2009 and Wan, Y. et al. NAR, 2010. Two color microarrays, comparing RNA from the experimental conditions (deletion mutations grown in YPD, WT and deletion mutations grown in YPD with TSA treatment) to RNA from the control WT cells grown in glucose-containing medium (YPD), were performed using Agilent whole-genome S. cerevisiae arrays.

Natural variation in the yeast glucose-signaling network reveals a new role for the Mig3p transcription factor

Project description:The Crabtree effect, in which fermentative metabolism is preferred at the expense of respiration, is a hallmark of budding yeast’s glucose response and a model for the Warburg effect in human tumors. While the glucose-responsive transcriptional repressors Mig1p and Mig2p play well-characterized roles in the Crabtree effect, little function for the related Mig3p transcription factor has been uncovered despite numerous investigations of laboratory yeast strains. Here we studied a wild isolate of Saccharomyces cerevisiae to uncover a critical role for Mig3p that has been lost in S288c-derived laboratory strains. We found that Mig3p affects the expression of hundreds of glucose-responsive genes in the oak strain YPS163, both during growth under standard conditions and upon ethanol treatment. Our results suggest that Mig3p may act as a multifunctional activator/repressor that plays separate roles under standard versus stress conditions, but this function has been largely lost in the lab strains. Population analysis suggests that the lab strain, and several wild strains, harbor mutations that diminish Mig3p function. Thus, by expanding our attention to multiple genetic backgrounds, we have uncovered an important missing link in a key metabolic response. We performed a series of microarray experiments comparing the gene expression response of unstressed or EtOH stressed wild-type or mig3∆ strains in either the BY4741 or YPS163 background (biological triplicates). We also compared gene expression for in reciprocal hemizygous strains (YPS163/BY4741mig3∆ and YPS163mig3∆/BY4742; biological duplicates). Lastly, we measured the gene expression of BY4741 over-expressing BY_MIG3 via galactose induction (biological triplicates).

Xylose metabolism in Candida utilis

Project description:A recombinant C. utilis strain expressing Candida shehatae xylose reductase K275R/N277D (NADH-preferring), C. shehatae xylitol dehydrogenase and Pichia stipitis xylulokinase produce ethanol from xylose. Here, we report the transcriptional-profiling in the engineered C. utilis strain grown on xylose using DNA microarray. Transcriptome analysis indicated that expression of genes encoding the tricarboxylic acid cycle, respiration enzymes and the ethanol consumption were increased significantly when cells were cultivated on xylose. Gene expression in Candida utilis cells grown on glucose or xylose was measured at 10.5 and 24 hours, respectively. Two or three independent experiments were performed at each time for each experiment.

Acetylation of histone H4 at lysine 44 facilitates meiotic recombination by creating accessible chromatin [ChIP-seq]

Project description:Meiotic recombination hotspots are associated with histone post-translational modifications and open chromatin. However, it remains unclear how histone modifications and chromatin structure directly regulate meiotic recombination. Here, we identify acetylation of histone H4 at Lys44 (H4K44ac) as a new histone modification, occurring on the nucleosomal lateral surface. We show that H4K44ac is specific to yeast sporulation, rising during yeast meiosis and displaying genome-wide enrichment at recombination hotspots in meiosis. The H4K44 residue is required for normal meiotic recombination, for normal levels of double strand breaks during meiosis, and for optimal sporulation. Non-modifiable substitution H4K44R results in reduced MNase digestion and decreased binding of recombination-associated proteins at hotspots. Our results show that H4K44ac creates an accessible chromatin environment for key proteins to facilitate meiotic recombination. One sample, H4K44ac chIP from 4hrs sporulation yeast and one background H4 chIP from the same, two replicates each Two replicates each of H3K4me3 and H3K56ac chIP-seq in WT and H4K44->R mutant yeast, with two replicates of H3 chIP-seq in each genetic background Two replicates each of Rad51 chIP-seq in WT and H4K44->R mutant yeast with a single replicate of accompanying input DNA in each genetic background

Microarray analysis for the Mode-of-Action study of resveratrol in fission yeast

Project description:An increasing number of studies have shown that the promising compound resveratrol treats multiple diseases, such as cancer and aging; however, the resveratrol mode-of-action (MoA) remains largely unknown. Here, by virtue of multiple omics approaches, we adopted fission yeast as a model system with the goal of dissecting the common MoA of the anti-proliferative activity of resveratrol. Fission yeast was chosen as the model because of the following reasons: fission yeast is a terrific model to investigate the cell cycle and cell shape; the yeast belongs to the âCrabtree Positiveâ yeast kingdom, which possesses features similar to the âWarburg Effectâ of cancer cells such that the fission yeast prefers to conduct fermentation with glucose as the carbon source for energy production ; many omics tools and datasets are available for the systematic exploration of the drugâs effects at different concentration. This experiment uses microarray analysis with the aim of exploring transcriptional modulation after natural product resveratrol treatment at the IC50 drug concentration, in fission yeast S.pombe.
