(Submitter supplied) Carbon dioxide (CO2) sensing, transport, and metabolism play a pivotal role in survival and proliferation of pathogenic microbes infecting human host from natural environments due to the drastic difference of CO2 levels. Carbonic anhydrases (CAs) are not only key CO2-metabolic enzymes catalyzing reversible interconversion between CO2 and bicarbonate (HCO3-), but also important CO2-signaling modulators. more...

(Submitter supplied) A family of APSES transcription factor is known to be fungal-specific transcriptional regulators and play important roles in governing growth, differentiation, and virulence of diverse fungal pathogens. Yet none of APSES-like transcription factors have been identified and investigated in a basidiomycetous fungal pathogen, Cryptococcus neoformans. In the present study we discovered an APSES-like transcription factor, Msa1 (Mbp1/Swi4-like APSES protein 1), as one of novel flucytosine-responsive genes (total 194 genes) identified through comparative transcriptome analysis of C. more...

(Submitter supplied) AP-1 like transcription factors play evolutionarily conserved roles in oxidative stress responses as redox sensors in eukaryotes. In this study, we aim to elucidate the regulatory mechanism of an atypical yeast AP-1 like protein, Yap1, in the stress response and virulence of Cryptococcus neoformans. YAP1 expression was induced not only by oxidative stresses, such as H2O2 and diamide, but also by other environmental stresses, such as osmotic and membrane destabilizing stresses. more...

(Submitter supplied) The cAMP-pathway plays a central role in regulation of growth, differentiation, and virulence of human pathogenic fungi, including Cryptococcus neoformans. Three major upstream signaling regulators of the adenylyl cyclase (Cac1), Ras, Aca1 (Adenylyl cyclase-associated protein 1) and G-alpha subunit protein (Gpa1), have been identified to control the cAMP-pathway in C. neoformans, but their functional relationship remains elusive. more...

(Submitter supplied) Thermotolerance is a crucial virulence attribute for Cryptococcus neoformans, which causes fatal fungal meningitis in humans. A protein kinase, Sch9, suppresses the thermotolerance of C. neoformans but its regulatory mechanism remains unknown. Here we elucidated the Sch9-dependent and -independent signaling networks for modulating the thermotolerance of C. neoformans through a genome-wide transcriptome analysis and reverse genetics approaches. more...

(Submitter supplied) Thermotolerance, a key factor essential for the virulence of pathogenic fungi including Cryptococcus neoformans, remains largely unexplored in terms of its underlying mechanism. In this study, our findings demonstrate that Set3C, a widely distributed and conserved histone deacetylase complex, is required for thermotolerance in Cryptococcus neoformans. Specifically, the deletion of the core subunit Set302, responsible for the integrity of the complex, results in a significant reduction in the growth ability under high stress and the viability at extreme temperature. more...

(Submitter supplied) Purpose: To identify the downstream gene sets regulated by Mpk1p in C. neoformans normal and Tunicamycin-treated conditions, we compared the RNA-seq based transcriptional profiles. Methods: Total RNA was isolated according to the RNeasy Mini Kit (Qiagen) and all procedure for RNA sequencing were conducted by ebiogen. The mRNA was isolated by using the Poly(A) RNA Selection Kit (LEXOGEN) and isolated mRNAs were used for the cDNA synthesis. more...

(Submitter supplied) WD40 motif-containing Msi1-like (MSIL) proteins play pleiotropic cellular functions as a negative regulator of the Ras/cAMP-pathways and a component of chromatin assembly factor-I (CAF-I), and yet have not been studied in fungal pathogens. Here we identified and characterized an MSIL protein, Msl1, in Cryptococcus neoformans, which can cause fatal meningoencephalitis in humans. Notably, Msl1 was not a functional ortholog for the yeast Msi1 but played pleiotropic roles in C. more...

(Submitter supplied) Cryptococcus neoformans is an opportunistic basidiomycete pathogen that is a major etiological agent of fungal meningoencephalitis leading to more than 180,000 deaths worldwide annually. For this pathogen, the polysaccharide capsule is a key virulence factor, which interferes with the phagocytosis by host innate immune cells, but its complex signaling networks remain elusive. In this study, we systematically analyzed capsule biosynthesis and signaling networks by using C. more...
