Abstract

Complex human diseases such as metabolic disorders, cancer, neurodegenerative diseases, and mitochondrial dysfunctions arise from the biochemical or genetic defects in various cellular processes. Therefore, it is important to understand which metabolic processes are affected by which cellular impairment. Because genome-wide screening of mutant collections (haploid/diploid deletion library) provides important clues for the understanding of conserved biological processes and for finding potential target genes, we screened the haploid mutant collection of Schizosaccharomyces pombe with wortmannin that inhibits phosphatidylinositol-3-kinase signaling. Using genome-wide screening, we determined that 52 mutants were resistant to this chemical. When 52 genes that are deleted in these mutants were grouped in 41 different biological processes, we found that 37 of them have human orthologues and 4 genes were associated with human metabolic disorders. In addition, when we examined the pathways in which these 52 genes function, we determined that 9 genes were related to phosphorylation process. These results might provide new insights for better understanding of certain human diseases.
