Identification of differentially expressed genes in yeast Saccharomyces cerevisiae cells with inactivated Mmf1p and Hmf1p, members of proteins family YERO57c/YJGF

摘要

We used differential display analysis of mRNA to investigate the differences between gene expression in wild-type (wt) yeast Saccharomyces cerevisiae cells and mutated ones with disrupted activity of genes MMF1 and HMF1, members of the YERO57c/YJGF family. Reverse transcription-polymerase chain reaction (RT-PCR) analysis was performed to determine the differences in the degree of expression of 14 specific transcripts in normal and mutated yeast cells. Obtained data demonstrate that disruption of genes encoding proteins Mmf1p, Hmf1p (or both of them) result in the correlative variation of expression level of the target 12 genes both in the cells with changed phenotype (mmf1 and mmf1 hmf1) and in the cells retaining w.t. shape and growth rate (wt cells, hmf1). Metabolic processes and cellular pathways have been indicated for Mmf1p and Hmf1p based on the different profiles of the expression of 14 genes in mmf1, hmf1 yeast S. cerevisiae cells.
