Microarray analyses of C. albicans sak1 deletion mutant in complex liquid medium (YPD)

ABSTRACT: Sak1 (orf19.3840) of Candida albicans was found to be a kinase which phosphorylates and thereby activates Snf1, a highly conserved regulator of nutrient stress responses. Accordingly, a sak1 deletion mutant failed to grow on many alternative (i.e., non-glucose) carbon sources, but also showed a filamentation defect upon growth under glucose limitation and exhibited reduced virulence. To better define the effects of Sak1 on C. albicans metabolic adaptations, these transcriptional analyses were performed in complex medium, using a sak1 deletion mutant in comparison to the wild type.

The metabolic flexibility of the opportunistic fungal pathogen Candida albicans is important for colonisation and infection of different host niches. Complex regulatory networks, in which protein kinases play central roles, link metabolism and other virulence-associated traits, such as filamentous growth and stress resistance, and thereby control commensalism and pathogenicity. By screening a protein kinase deletion mutant library that was generated in the present work using an improved SAT1 fli ...[more]

Response of Candida albicans to taurocholate

Project description:Presence of taurocholate (TC), a constituent of bile, confers resistance of Candida albicans to antifungals like Caspofungin and Amphotericin B. Transcriptional profiles in presence and absence of TC were compared to determine whether an upregulation of known resistance genes is responsible for this effect. No upregulation was found, and the resistance seemed to be rather based on a direct interaction of TC with the antifungals.

Microarray experiment of Candida albicans candidalysin mutants in yeast and hypha morphology

Project description:The effect of the deletion of the hyphae-associated toxon of Candida albicans, camdidalysin, on yeast and hyphae tramscriptomes was tested with different mutants. Tested strains include the wild type (SC5314), deletion mutants of candidalyin and of ECE1 (the gene encoding the polyprotein that includes candidalysin) and an ECE1 revertant strain. Each were tested in yeast- and in hypae-supporting growth conditions.

Severe alkaline pH stress induces a glucose starvation-related transcriptional response in S. cerevisiae

Project description:Alkaline pH stress invokes in S. cerevisiae a potent and fast transcriptional response that includes many genes repressed by glucose. Certain mutants in the glucose-sensing and response pathways, such as those lacking the Snf1 kinase, are sensitive to alkalinization. We show that addition of glucose to the medium improves growth of wild type cells at high pH, fully abolish the snf1 alkali-sensitive phenotype and attenuates high pH-induced Snf1 phosphorylation at Thr210. The elm1 mutant, lacking one of the three upstream Snf1 kinases (tos3, elm1 and sak1), is markedly alkali sensitive, whereas the phenotype of the tos3 elm1 sak1 strain is even stronger than that of snf1 cells and it is not fully rescued by glucose supplementation. DNA microarray analysis reveals that about 75% of genes induced at short term by high pH are also induced by glucose scarcity. Snf1 mediates, in full or in part, the activation of a significant subset (38%) of short-term alkali-induced genes, including those coding high-affinity hexose transporters and phosphorylating enzymes. Induction of genes encoding enzymes involved in glycogen (but not trehalose) metabolism is largely dependent of the presence of Snf1. Therefore, the function of Snf1 in adaptation to glucose scarcity appears crucial for alkaline pH tolerance. Incorporation of micromolar amounts of iron and copper to a glucose-supplemented medium result in an additive effect and allows near normal growth at high pH, thus indicating that these three nutrients are key limiting factors for growth in an alkaline environment. We identified the changes in the expression profiles caused by alkalinization of the medium (pH8 vs. pH5.5 for 10 min) in several strains: wild type cells (4 chips), snf1 mutant cells (4 chips) We also identified the transcriptomic changes that occur after glucose deprivation (0.05% vs 2% for 15 min) in: wild type cells (2 chips) snf1 mutant cells (2 chips) Total: 12 chips

Multiple phosphorylation sites regulate the activity of the repressor Mig1 in Candida albicans

Project description:The highly conserved heterotrimeric protein kinase SNF1 is important for metabolic adaptations in the pathogenic yeast Candida albicans. A key function of SNF1 is to inactivate the repressor protein Mig1 and thereby allow the expression of genes that are required for the the utilization of alternative carbon sources when the preferred carbon source glucose is absent or becomes limiting. However, how SNF1 controls Mig1 activity in C. albicans has remained elusive. Using a phosphoproteomic approach, we found that Mig1 is phosphorylated at multiple serine residues. Replacement of these serine residues by nonphosphorylatable alanine residues strongly increased the repressor activity of Mig1 in cells lacking a functional SNF1 complex, indicating that additional protein kinases are involved in the regulation of Mig1. Unlike wild-type Mig1, whose levels strongly decreased when the cells were grown on sucrose or glycerol instead of glucose, the levels of a mutant Mig1 protein lacking nine phosphorylation sites remained high under these conditions. Despite the increased protein levels and the absence of multiple phosphorylation sites, cells with a functional SNF1 complex could still sufficiently inhibit the hyperactive Mig1 to enable wild-type growth on alternative carbon sources. In line with this, phosphorylated forms of the mutant Mig1 were still detected in the presence and absence of a functional SNF1, demonstrating that Mig1 contains additional, unidentified phosphorylation sites and that downstream protein kinases are involved in the control of Mig1 activity by SNF1.

Chemical genomics study of Snf1 as a gene repressor

Project description:The Snf1 kinase plays a critical role in recalibrating cellular metabolism in response to glucose depletion. Hundreds of genes show changes in expression levels when the SNF1 gene is deleted. However, cells can adapt to the absence of a specific gene when grown in long term culture. Here we apply a chemical genetic method to rapidly and selectively inactivate a modified Snf1 kinase using a pyrazolopyrimidine inhibitor. By allowing cells to adjust to a change in carbon source prior to inhibition of the Snf1 kinase activity, we identified a set of genes whose expression increased when Snf1 was inhibited. Prominent in this set are genes that are activated by Gcn4, a transcriptional activator of amino acid biosynthetic genes. Deletion of Snf1 increased Gcn4 protein levels without affecting its mRNA levels. The increased Gcn4 protein levels required the Gcn2 kinase and Gcn20, regulators of GCN4 translation. These data indicate that Snf1 functions upstream of Gcn20 to regulate control of GCN4 translation.
