(Submitter supplied) In this study, we have investigated Mediator function in the human fungal pathogen C. albicans. An initial screening of conditionally regulated Mediator subunits showed that the Med7 of C. albicans was not essential, in contrast to the situation noted for Saccharomyces cerevisiae. While loss of CaMed7 did not lead to loss of viability under normal growth conditions, it dramatically influenced the pathogen’s ability to grow in different carbon sources, to form hyphae and biofilms, and to colonize the gastrointestinal tracts of mice. more...

(Submitter supplied) Analysis of the role of the Candida dubliniensis Telomeric (TLO) genes and MED3, encoding subunits of Mediator, in regulating transcription The transcriptional response of a Candida dubliniensis TLO1/TLO2 double (null) mutant was analysed. Reintegrant strains harboring TLO1 or TLO2 were compared to this null mutant to elucidate the individual role of each ORF. The role of MED3 was compared also.

(Submitter supplied) Morphogenetic transitions are prevalent in the fungal kingdom. For a leading human fungal pathogen, Candida albicans, the capacity to transition between yeast and filaments is key for virulence. For the model yeast Saccharomyces cerevisiae, filamentation enables nutrient acquisition. A recent functional genomic screen in S. cerevisiae identified Mfg1 as a regulator of morphogenesis that acts in complex with Flo8 and Mss11 to enable transcriptional responses crucial for filamentation. more...

(Submitter supplied) Biofilm development by Candida albicans requires cell adhesion for the initial establishment of the biofilm and the continued stability after hyphal development occurs; however, the regulation of the process has not been fully established. Using chromatin immunoprecipitation coupled to microarray analysis (ChIP-chip) we have characterized a regulon containing the Mcm1p factor that is required for the initial surface adhesion during biofilm formation. more...

(Submitter supplied) Candida albicans is the most common opportunistic fungal pathogen of humans and is also a benign member of the gastrointestinal (GI) tract microbiota. Morphological transitions and metabolic regulation are critical for C. albicans to adapt to the changing host environment. We generated a library of central metabolic pathway mutants in the tricarboxylic acid (TCA) cycle, and investigated the functional consequences of these gene deletions on C. more...

(Submitter supplied) Skn7 is a conserved fungal heat shock factor-type transcriptional regulator. It participates in maintaining cell wall integrity and regulates the osmotic/oxidative stress response (OSR) in S. cerevisiae, where it is part of a two-component signal transduction system. Here, we comprehensively address the function of Skn7 in the human fungal pathogen Candida albicans. We provide evidence reinforcing functional divergence, with loss of the cell wall/osmotic stress-protective roles and acquisition of the ability to regulate morphogenesis on solid medium. more...

(Submitter supplied) Cap1p, a transcription factor of the basic region-leucine zipper family, regulates oxidative stress response (OSR) in Candida albicans. Alteration of its C-terminal cysteine-rich domain (CRD) results in Cap1p nuclear retention and transcriptional activation. To better understand the function of Cap1p in C. albicans, we used genome-wide location profiling (ChIP-on-chip) to identify its transcriptional targets in vivo. more...

(Submitter supplied) Cap1p, a transcription factor of the basic region-leucine zipper family, controls the oxidative stress response in Candida albicans. It was shown that alteration of the C-terminal cysteine-rich domain (CRD) of Cap1p results in nuclear retention and constitutive transcriptional activation. To further characterize the function of Cap1p in C. albicans, we used genome-wide location profiling (ChIP-on-chip), allowing the identification of Cap1p-transcriptional targets in vivo. more...

(Submitter supplied) To study the transcriptome in developing heart controlled by the intact Mediator complex. RNA-seq analysis was performed on RNA extracted from hearts of Med30 cKO and control littermates at E10.5. From this analysis, 10,637 genes were expressed in both mutant and control cardiomyocytes. Of these, 31 genes were significantly upregulated, and 45 genes were significantly downregulated (log2fold > 1, adjusted p value < 0.05) in mutant cardiomyocyte relative to controls. more...

(Submitter supplied) The ATAC histone acetyl-transferase (HAT) and the Mediator coactivator complexes regulate independent and distinct steps during transcription initiation and elongation. Here we report the identification of a new stable molecular assembly formed between the ATAC and the Mediator complex in mouse embryonic stem cells. Moreover, we identify LUZP1 as a subunit of this meta coactivator complex (MECO). Finally, we demonstrate that MECO regulates a subset of RNA polymerase II transcribed non-coding RNA genes. more...

(Submitter supplied) Background : Candida albicans is a diploid pathogenic fungus not yet amenable to routine genetic investigations. Understanding aspects of the regulation of its biological functions and the assembly of its protein complexes would lead to further insight into the biology of this common disease-causing microbial agent. Results: We have developed a toolbox allowing in vivo protein tagging by PCR-mediated homologous recombination with TAP, HA and MYC tags. more...

(Submitter supplied) The yeast Mediator complex can be divided into three modules, designated Head, Middle and Tail. Tail comprises the Med2, Med3, Med5, Med15 and Med16 protein subunits, which are all encoded by genes that are individually non-essential for viability. In cells lacking Med16, Tail is displaced from Head and Middle. However, inactivation of MED5/MED15 and MED15/MED16 are synthetically lethal, indicating that Tail performs essential functions as a separate complex even when it is not bound to Middle and Head. more...
