The chemiluminescent assay of menadione-catalysed H2O2 production by living mammalian cells was proposed to be useful for rapid food safety evaluation. The tested foods were extracted with water, ethanol and dimethylsulfoxide, and each extract was incubated with NIH3T3, Neuro-2a and HepG2 cells for
Entomopathogenic fungi are predisposed to ROS induced by heat and UV-A radiation when outside the insect host. When inside the host, they are subject to phagocytic cells that generate ROS to eliminate invading pathogens. The oxidative stress tolerance of the entomopathogenic fungi Aschersonia
The MuS1 gene is highly homologous to many stress-related proteins in plants. Here, we characterized whether a new candidate gene, MuS1, is related to multiple stress tolerance in yeast as it is in plants. Transgenic yeast strain expressing MuS1 were more resistant to hydrogen peroxide, menadione,
Elevated tolerance to UV-B radiation and heat may be induced in conidia produced on fungi exposed during mycelial growth to sublethal stresses other than heat or UV-B. This is due to a phenomenon referred to as 'cross-protection'. Several mechanisms are associated with this increased conidial
FvatfA from the maize pathogen Fusarium verticillioides putatively encodes the Aspergillus nidulans AtfA and Schizasaccharomyces pombe Atf1 orthologous bZIP-type transcription factor, FvAtfA. In this study, a ΔFvatfA deletion mutant was constructed and then genetically complemented with the fully
α-Solanine and α-chaconine are well-known potato toxins, but the mechanism of the synergistic cytotoxic effect of these alkaloids has been little clarified. This study confirmed their synergistic cytotoxic effects on C6 rat glioma cells by three different cell viability tests, namely WST-1
