Project description:Transcript analyses of cisplatin and Sky1 effects in Saccharomyces cerevisiae

Project description:In this study, we used Saccharomyces cerevisiae to investigate the effects of GRX deletion on yeast chronological life span (CLS). Deletion of Grx1 or Grx2 shortened yeast CLS. Quantitative proteomics revealed that GRX deletion increased cellular ROS levels to activate Ras/PKA signal pathway. Our results provided new insights into mechanisms underlying aging process.

Project description:Ixr1 is a Saccharomyces cerevisiae HMGB protein that regulates the transcription of genes related to the response to changes normoxia-hypoxia, oxidative stress response or in the readaptation of catabolic and anabolic fluxes during oxygen limitation. Besides, Ixr1 binds to cisplatin-DNA adducts with high affinity. It is known that cancerous cells usually acquire resistance against the drug after the initial treatment, thus limiting its effectiveness. Yeast has been used as an easy-handled eukaryotic model to find genes related to cisplatin responsiveness and IXR1 is one among those that increase sensitivity. In this work, transcriptome analyses have been done to understand the regulatory roles of Ixr1 in absence or presence of cisplatin. Ixr1 behaves in yeast as a master regulator of other transcriptional factors, which respond to external stimuli and control cell growth, and proliferation. Diverse approaches including qPCR, ChIP and measure of 18S and 25S rRNAs confirm a function of Ixr1 in the control of ribosome biogenesis. Furthermore, several connections between this control, the TOR signaling pathway and cisplatin resistance in ixr1Δ mutants were found.

Project description:Sky1 is a Saccharomyces cerevisiae rich serine-arginine (SR) protein-specific kinase and its enzymatic activity is essential in the cytotoxicity caused by cisplatin, although the molecular mechanisms supporting this function are not understood. We present a transcriptome analysis discriminating between RNA changes induced by cisplatin which are dependent or independent of the Sky1 function.

Project description:Saccharomyces cerevisiae is an excellent microorganism for industrial succinic acid production, but high succinic acid concentration will inhibit the growth of Saccharomyces cerevisiae then reduce the production of succinic acid. Through analysis the transcriptomic data of Saccharomyces cerevisiae with different genetic backgrounds under different succinic acid stress, we hope to find the response mechanism of Saccharomyces cerevisiae to succinic acid.

Project description:To understand the gene expression in Saccharomyces cerevisiae under fermentative and respiraotry conditions, we perfomred the genome-wide gene expression profiling for the log-phase cells of S. cerevisiae wild type, sef1 deletion, and hyperactive SEF1-VP16 mutants under the YPD and YPGly conditions.

Project description:Sky1 is a Saccharomyces cerevisiae rich serine-arginine (SR) protein-specific kinase and its enzymatic activity is essential in the cytotoxicity caused by cisplatin, although the molecular mechanisms supporting this function are not understood. We present a transcriptome analysis discriminating between RNA changes induced by cisplatin which are dependent or independent of the Sky1 function. The S. cerevisiae strain W303 (MATa ade2-1 can1-100 leu2-3,112 trp1-100 ura3- 52) and its derivative W303-M-NM-^Tsky1 previously described (RodrM-CM--guez- Lombardero et al., 2012) have been used in these analyses. Biological replicates of cultures and treatments were run in triplicate. The yeast cells were pre-cultured over night in 10mL of complete synthetic medium (SD) prepared as previously described (Zitomer and Hall, 1976). The following day the cells were inoculated at initial OD600 of 0.4 in 70 mL SD and grown in 250 mL Erlenmeyer flasks at 30 M-BM-:C and with agitation at 250 rpm. When cells reached OD600 of 0.6, the cultures from each strain were divided in two aliquots of 25 mL (control and cisplatin treatment). A stock solution of cisplatin 6 mM in dimethyl sulfoxide (DMSO) was prepared and the drug was added to the treated cultures at a final concentration of 600 microM. An equivalent volume of DMSO was added to the control cultures. The treatment was done at 30M-BM-:C and with agitation at 250 rpm during four hours in darkness. RNA was extracted from a number of cells corresponding to OD600 of 3 with the AurumTM Total RNA Mini Kit (Bio-Rad) and following the manufacturerM-bM-^@M-^Ys instructions. The RIN parameter (RNA Integrity Number) evaluated with the 2100 was near to the value 9 in all the samples. Three different RMA analyses were performed: Analysis 1: GSM1008483-GSM1008488 Analysis 2: GSM1008489-GSM1008494 Analysis 3: GSM1008495-GSM1008500
