Project description:In S. cerevisiae, the phosphate starvation (PHO) responsive transcription factors Pho4 and Pho2 are jointly required for induction of phosphate response genes and survival in phosphate starvation conditions. In the related human commensal and pathogen C. glabrata, Pho4 is required but Pho2 is dispensable for survival in phosphate-limited conditions and is only partially required for inducing the phosphate response genes. This reduced dependence on Pho2 evolved in C. glabrata and closely related species. Pho4 orthologs that are less dependent on Pho2 induce more genes when introduced into the S. cerevisiae background, and Pho4 in C. glabrata both binds to more sites and induces more genes with expanded functional roles compared to Pho4 in S. cerevisiae. We used Chromatin-ImmunoPrecipitation with exonucleas followed by high-throughput sequencing (BioChIP-seq) to identify the binding locations of Pho4 from both S. cerevisiae and C. glabrata in the S. cerevisiae background lacking the negative regulator Pho80, and either with or without Pho2.

Project description:Eukaryotic transcription activators stimulate the expression of specific sets of target genes through recruitment of co-activators such as the RNA polymerase II-interacting Mediator complex. We previously identified an activator-targeted ~85 amino acid three-helix bundle KIX domain in the human MED15 Mediator subunit that is structurally conserved in Gal11 Mediator subunits in fungi. The Gal11 KIX domain is engaged by pleiotropic drug resistance transcription factor (Pdr1) orthologues, key regulators of the multidrug resistance (MDR) pathway in S. cerevisiae and in the clinically important human pathogen Candida glabrata. Drug-resistant clinical isolates of C. glabrata most commonly harbour point mutations in Pdr1 that render it constitutively active, suggesting that this transcriptional activation pathway may represent a lynchpin in C. glabrata MDR. We have now carried out sequential biochemical and in vivo high-throughput screens to identify small molecule inhibitors of the interaction of the C. glabrata Pdr1 activation domain with the C. glabrata Gal11A KIX domain. The lead compound (iKIX1) inhibits Pdr1-dependent gene activation in both S. cerevisiae and C. glabrata and re-sensitizes drug-resistant C. glabrata to effective azole antifungal concentrations in vitro and in animal models for disseminated and urinary tract C. glabrata infection.

Project description:Candida glabrata is a human-associated opportunistic fungal pathogen. It shares its niche with Lactobacillus spp. in the gastrointestinal and vaginal tract. In fact, Lactobacillus species are thought to competitively prevent Candida overgrowth. We investigated the molecular aspects of this antifungal effect by analyzing the interaction of C. glabrata strains with Limosilactobacillus fermentum. From a collection of clinical C. glabrata isolates, we identified strains with different sensitivities to L. fermentum in coculture. We analyzed the variation of their expression pattern to isolate the specific response to L. fermentum. C. glabrata-L. fermentum coculture induced genes associated with ergosterol biosynthesis, weak acid stress, and drug/chemical stress. L. fermentum coculture depleted C. glabrata ergosterol. The reduction of ergosterol was dependent on the Lactobacillus species, even in coculture with different Candida species. We found a similar ergosterol-depleting effect with other lactobacillus strains (Lactobacillus crispatus and Lactobacillus rhamosus) on Candida albicans, Candida tropicalis, and Candida krusei. The addition of ergosterol improved C. glabrata growth in the coculture. Blocking ergosterol synthesis with fluconazole increased the susceptibility against L. fermentum, which was again mitigated by the addition of ergosterol. In accordance, a C. glabrata Derg11 mutant, defective in ergosterol biosynthesis, was highly sensitive to L. fermentum. In conclusion, our analysis indicates an unexpected direct function of ergosterol for C. glabrata proliferation in coculture with L. fermentum.

Project description:Transcriptional profiling of Candida glabrata zap1Δ and zap1Δ::ZAP1 strains, comparing cells grown under planktonic and biofilm-inducing conditions. Goal was to analyse the effect of ZAP1 deletion in the transcriptomic profile of C. glabrata biofilm cells (in comparision to planktonic cells), under acidic conditions, in order to study the function of the Zap1 transcription factor in C. glabrata biofilm matrix production.

Project description:The goal of the current study was to identify differentially-expressed genes upon CgSNF2 deletion, as well as, upon macrophage internalization in C. glabrata wild-type (wt) and Cgsnf2Δ strains. For this study, RNA samples were collected from RPMI-grown and macrophage-internalized cells of C. glabrata wild-type and Cgsnf2Δ strains at 2 h and 10 h post-infection. Comparative transcriptome analysis shows the differential regulation of 1419 genes in C. glabrata wild-type cells upon macrophage internalization, whereas the CgSNF2 deletion leads to altered regulation of 935 genes in C. glabrata wild-type cells.
