Abstract

Introduction: The reversibility of biological processes is an important challenge in the study of environmental pollutants and also natural and artificial radiation. There are many pieces of evidence about the reversible and irreversible effects of UV radiation on the human body. Assessment of the reversibility of UV laser effects on Saccharomyces cerevisiae was the aim of this study. Methods: Gene expression alteration in S. cerevisiae samples radiated by a 30s UV laser for 15, 30, and 60 minutes post-radiation times were investigated via network analysis to explore time-dependent reversible alteration in the gene expression profiles of the samples. Results: 19 differentially expressed genes (DEGs) were identified as targeted genes for the samples which were harvested 60 minutes after radiation; network analysis revealed no significant alteration in biological processes. Conclusion: It can be concluded that the gross effects of the UV laser on S. cerevisiae samples disappear after 60 minutes of radiation.

Keywords: Network analysis; Post-radiation time; Radiation; Repair; Saccharomyces cerevisiae.
