Project description:The SCH9 null strain has smaller cell size, grows at a slower rate and survives three times longer than wide-type yeast. This study aims to dissect the mechanisms that lead to the yeast life span extension of sch9-delta. We measure gene expression profiles of the S. cerevisiae wild type and the long-lived sch9∆ strain every 12 hours from 12 to 120 hours. At each time point, one sample is hybridized to one Affymetrix GeneChip Yeast 2.0 array. In total, ten time points are measured for each strain. When we perform a check of the data quality, all arrays look normal except the 120-hour sch9∆ array. Thus we abandon this array in the further data analysis.

Project description:The Target Of Rapamycin (TOR) protein is a Ser/Thr kinase that functions in two distinct multiprotein complexes: TORC1 and TORC2. These conserved complexes regulate many different aspects of cell growth in response to intra- and extracellular cues. Here we report the first bona fide substrate of yeast TORC1: the AGC-kinase Sch9. Six amino acids in the c-terminus of Sch9 are directly phosphorylated by TORC1. Phosphorylation of these residues is lost upon rapamycin-treatment as well as carbon- or nitrogen-starvation and transiently reduced following application of osmotic, oxidative or thermal stress. TORC1-dependent phosphorylation is required for Sch9 activity and replacement of residues phosphorylated by TORC1 with Asp/Glu renders Sch9 activity TORC1-independent. Sch9 is required for TORC1 to properly regulate ribosome biogenesis, translation initiation and entry into G0 phase, but not expression of Gln3-dependent genes. Our results suggest that Sch9 functions analogously to the mammalian TORC1 substrate S6K1 rather than the mTORC2 substrate PKB/Akt. Keywords: time course, cell type.

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:This study explores the connection between changes in gene expression and the genes that determine strain survival during suspension culture, using the model eukaryotic organism, Saccharomyces cerevisiae. The Saccharomyces cerevisiae homozygous diploid deletion pool, and the BY4743 parental strain were grown for 18 hours in a rotating wall vessel, a suspension culture device optimized to minimize the delivered shear. In addition to the reduced shear conditions, the rotating wall vessels were also placed in a static position or in a shaker in order to change the amount of shear stress on the cells. Keywords: shear stress, time course

Global transcriptional analysis of rapamycin response was conducted on cells expressing either a wild-type, Sch9(WT), or TOR-independent allele of Sch9, Sch9(2D3E). Reference samples used were cells collected immediately prior to rapamycin treatment for the respective cell genotypes. Test samples were collected 20, 30, 60, 90, 120, and 180min post rapamycin treatment.
