Effect of plasma irradiation for an application of plasma medicine has been investigated, and active species generated in plasma probably play an important part in a reaction between plasma and biological subjects relating to living organisms. In this study, gene expression variation of yeast, Saccharomyces cerevisiae, treated by floating-electrode dielectric barrier discharge (FE-DBD) as an atmospheric plasma source was analyzed by DNA microarray method. As a result, it has been found that the variance of gene expression caused by FE-DBD plasma irradiation was detected. The variance of gene expression will be investigated by using a data on a biochemical pathways for analyzing a detail about effect of plasma irradiation to living organisms.
