Transcription profiling of wild type and hog1 Candida albicans subjected to environmental stresses that are known to activate the Hog1 Stress-activated Protein Kinase

Project description:Based on studies in S. pombe (Chen et al., 2003), we predicted that conditions which activate C. albicans Hog1 would result in the induction of a common set of genes that are regulated by this SAPK (Smith et al., 2004). Hence in this study we compared the global transcriptional responses of wild-type and hog1 C. albicans cells to environmental stresses that are known to activate the Hog1 SAPK. We compared the homozygous hog1/hog1 null mutant (JC50) with the isogenic HOG1 reintegrant (hog1/hog1/HOG1: JC52) because this controlled for any secondary mutations that might have been introduced during the construction of the null mutant. We have shown that this reintegrant is indistinguishable from its parental wild-type strain RM1000 (HOG1/HOG1) with respect to their stress phenotypes (Smith et al., 2004) and their expression of stress genes (Supplementary Data). Three conditions were chosen for transcript profiling: osmotic stress imposed by 0.3 M NaCl, oxidative stress imposed by 5 mM H2O2, and heavy metal stress imposed by 0.5 mM CdSO4. Each of these treatments stimulates the phosphorylation and nuclear accumulation of this Hog1 SAPK within a 10-min time frame (Smith et al., 2004). Furthermore, significant differences in stress regulated gene expression are observed within this time scale (Enjalbert et al., 2003; Smith et al., 2004). Hence, we analyzed the C. albicans transcriptome after a 10-min exposure to each stress condition. Although some stress genes might be missed by analyzing a single time point, most C. albicans stress genes are induced within 10 min (Enjalbert et al., 2003). At least four independent biological replicates were analyzed for each condition

Hog1 bypasses stress-mediated down-regulation of transcription by PolII redistribution and chromatin remodeling

Project description:Cells are subjected to dramatic changes on gene expression upon environmental changes. Stress causes a general down-regulation of gene expression together with the induction of a set of stress-responsive genes. Genome wide localisation studies showed major changes on Pol II localisation towards stress-responsive genes in contrast to housekeeping genes. Pol II relocalisation requires of the Hog1 SAPK, which also associates at stress-responsive loci. Chromatin structure was not significantly altered upon stress except for those genes that displayed Hog1 association. Together, Hog1 serves to bypass the general down-regulation of gene expression by targeting RNA Pol II machinery and inducing chromatin remodeling at stress-responsive loci. Hog1 and Pol II ChIP-Seq and Mnase-Seq experiments in both strains WT and Hog1 mutant, for 2 conditions: Exposed and not exposed to osmostress

Nuclear Localization of Hog1 MAPK is Not Necessary for Resistance to Hyperosmotic Stress

Project description:In budding yeast, this signaling pathway— the high-osmolarity glycerol (HOG) response —culminates in dual phosphorylation and nuclear translocation of the MAPK, Hog1 (ortholog of mammalian p38/SAPK). Induction of at least 50 genes requires nuclear Hog1, implying that transcriptional up-regulation is necessary to cope with hyperosmotic stress. Contrary to this expectation, we found that cells lacking the karyopherin (Nmd5) required for Hog1 nuclear import or in which Hog1 was permanently anchored at the plasma membrane(HOG1-CCAAX) (or both) withstood hyperosmotic challenge by three different solutes (1 M sorbitol, KCl or NaCl). In cells where activated Hog1 is excluded from the nucleus, there was little change in transcriptional program after exposure to hyperosmotic shock (comparable to hog1∆ cells), as judged by examining several diagnostic mRNAs and by global transcript measurements using microarrays. Systematic genetic analysis ruled out the need for any transcription factor known to be influenced by Hog1 (Hot1, Msn2, Msn4, Sko1 and Smp1). Keywords: Time course of stress response gene expression array
