Previously we found that this disadvantageous side effect can be counteracted by menadione sodium bisulfite (MSB) induced oxidative stress treatment. The fungus specific protein phosphatase Z1 (CaPpz1) has a pivotal role in oxidative stress response of Candida albicans and was proposed as a potential antifungal drug target. The aim of this study was to investigate the combined effects of CaPPZ1 gene deletion and MSB treatment in BM pre-treated C. albicans cultures. We found that the combined treatment increased redox imbalance, enhanced the specific activities of antioxidant enzymes, and reduced the growth in cappz1 mutant (KO) strain. RNASeq data demonstrated that the presence of BM markedly elevated the number of differentially expressed genes in the MSB treated KO cultures. Accumulation of reactive oxygen species, increased iron content and fatty acid oxidation, as well as the inhibiting ergosterol biosynthesis and RNA metabolic processes explain, at least in part, the fungistatic effect caused by the combined stress exposure. We suggest that the synergism between MSB treatment and CaPpz1 inhibition could be considered in developing of a novel combinatorial antifungal strategy accompanying steroid therapy.}, keywords = {PLASMA; RESISTANCE; GENE-EXPRESSION; SUSCEPTIBILITY; YEAST; microbiology; Fungi; glucocorticoid; Candida albicans; menadione; menadione; ATPASE; stress response; ANTIFUNGAL THERAPY; Combinatorial stress; Oxidative stress; protein phosphatase Z1; HOST COPPER}, year = {2021}, eissn = {2309-608X}, orcid-numbers = {Antal, Károly/0000-0001-8993-3314} } @article{MTMT:32089120, title = {Egy gombaspecifikus enzim, a protein foszfatáz Z jellemzése}, url = {https://m2.mtmt.hu/api/publication/32089120}, author = {Dombrádi, Viktor Béla}, journal-iso = {BIOKÉMIA}, journal = {BIOKÉMIA: A MAGYAR BIOKÉMIAI EGYESÜLET FOLYÓIRATA}, volume = {XLV}, unique-id = {32089120}, issn = {0133-8455}, year = {2021}, eissn = {2060-8152}, pages = {22-35} } @article{MTMT:31815661, title = {The phosphatome of opportunistic pathogen Candida species}, url = {https://m2.mtmt.hu/api/publication/31815661}, author = {Szabó, Krisztina and Miskei, Márton and Farkas, Ilona and Dombrádi, Viktor Béla}, doi = {10.1016/j.fbr.2020.12.002}, journal-iso = {FUNG BIOL REV}, journal = {FUNGAL BIOLOGY REVIEWS}, volume = {35}, unique-id = {31815661}, issn = {1749-4613}, abstract = {Several Candida species, the best known example of which is Candida albicans, are opportunistic human pathogens that are responsible for frequent nosocomial infections. A worrisome aspect of the currently available treatments of candidemia is the steady development of resistance to antifungals among these potentially life threatening fungi. Under these circumstances the search for novel drug targets is a well justified research direction. We propose that the principles of signal transduction therapy by targeting protein phosphatases can be adopted as these enzymes carry out important physiological functions in Candida. We demonstrate that C. tropicalis, C. albicans, C. dubliniensis, and S. cerevisiae exhibit the largest repertoire of protein phosphatases among the investigated fungi. Together with other opportunistic pathogen Candida species and the members of the Saccharomycetales order, they expanded their phosphatome by repeated gene duplications. We noted that evolution generated a set of fungus specific phosphatases which can be targeted without the danger of causing undesirable side effects in the human body. Based on the conflicting criteria of effectiveness and selectivity, we identified and characterized 7 phosphatases that are potent virulence determinants and may be utilized as potential antifungal drug targets.
